　　My fellow and my friends；

　　Once I read a piece of news report. It says， ＂A middle school student in a remote mountainous area was doing his revision at home one day. His brother， whose age excelled school age， was playing and drawing on the paper with his elder brother＇s pencil at his side. Suddenly the younger brother raised his head thoughtfully， his little eyes were winking， and said to his brother seriously， ＂When will it thirty-second， brother？＂ The elder brother looked at his innocent younger brother and said with a smile， ＂What are you going to do on that thirty-second？＂ ＂Papa promised me to send me to school，＂ said his younger brother. His brother， the middle school student looked at his lovely brother and his heart seemed to be stitched with needles. My God！ My parents were working day and night in order to be able to afford my schooling. They were exhausted. How could they afford my younger brother＇s schooling？ Oh， thirty-second ...

　　My dear friends， hearing this， didn＇t you feel sorry for them？ We share the same native land， the same blue sky under the sun. Why cannot they be given lesson at school， sitting in the bright and big classroom？ We are used to saying that education goes first before vitalizing the country. But now the country＇s fiscal solvency and material resources are not ample enough. What should we do？ It requires that we should be of one heart and exert our efforts for our motherland.

　　同胞们，朋友们：

　　我曾看过这样一则报道：＂某边远山区一个中学生，一天在家复习功课，一旁的已过入学年龄的小弟弟拿他的铅笔在纸上写着、涂着、画着，突然若有所思地仰起小脸，眨巴几下小眼睛，认真地问：＇哥哥，什么时候才到32号呀？＇这位中学生看看天真的小弟弟，笑着逗他：＇32号你要干啥？＇＇爸爸说，到32号才能送我去上学。＇中学生望着可爱的小弟弟，内心针扎般难受：天哪，父母为了供自己上学，整日操劳，身体都累垮了，哪还有能力再送弟弟上学？啊！32号......＂

　　朋友们，当你听了这个故事，你不感到痛心吗？同在一片故土上，同在一片蓝天下，为什么他们不能坐在宽敞明亮的教室里去读书？我们常说：国家要振兴，教育须先行。而我国的财力、物力都不宽裕，怎么办？这就需要全社会的人齐心协力为国家分忧，为国家出力！

　　Good morning ladies and gentleman. My name is Miller. I’d like to talk to you today about the topic of Traffic Jams in Shanghai. The purpose of this talk is to analysis the problem of traffic jams and try to make some advices in my view. I shall only take about four minutes of your times. I’ve divided my presentation into three parts.

　　First. Status. Yesterday, I went to XuJiaHui. I start my route at 1:00pm. When I arrived home, it was 8:00pm. I only use nearly 3 hours on shopping. That means I almost waste 4 hours on the way. That is the Traffic Jams Status in Shanghai.

　　Second. Reasons. I found that the traffic management is the most serious problem in the traffic system. In some important crossroads, there are no enough traffic police to do the traffic grooming. It’s irrational. We paid so much taxes, but we cannot comfort what we should get. For example, on the overhead, two cars had made a traffic accident. This leaded the traffic jams. We had not see the traffic police from start to end. It took me nearly 10 minutes on the overhead. It was happened yesterday.

　　Third. To solve it. What I can advice is just add more traffic polices in the important crossroads. It’s the most useful way to solve the traffic jams. Because yesterday when we nearly went out the overhead, the speed was increased obviously. We found several traffic polices in the crossroad. They commanded cars and then the traffic went well.

　　That brings me to the end of my presentation. Let me just run over the key points again. Traffic jams was made by several resources. To solve it, we can depend on the traffic police. But for ourselves, to drive more carefully, more reasonably, maybe is another way to decrease the traffic jams.

　　Thank you for your attention. Any questions?

　　One possible version:

　　Boys and girls:

　　We high school students do have some growing pains, but we can get rid of them correctly and wisely. First of all, some of us are upset about their figures and looks. Personally, I argue that it is one's inner beauty that really matters. That is why we needn't care about it.

　　Second, when we are misunderstood by our teachers, parents or even classmates, we can find a proper time to have a heart-to-heart talk with them, as communication is the best way to remove misunderstandings. Some of us complain they have few true friends. Being open-minded and ready to help others will surely gain popularity among peers.

　　Third, we may fall behind others, which makes us stressed. Determined to work efficiently, we can overcome any difficulty. If necessary, we may turn to the teachers for help.

　　Last, some of us don't have much pocket money, so they feel unhappy. Isn't it strange? So long as we have some, that's enough. We high school students should learn to save, as saving is a good virtue of the Chinese, shouldn’t we?

　　That's all. Thank you.

　　A man went to an insurance office to have his life insured. The manager of the office asked him how old his parents were when they died.

　　“Mother had a bad heart and died at the age of thirty. Father died of tuberculosis when he was thirty-five.”

　　“I am very sorry,”said the manager,“we cannot insure your life as your parents were not healthy.”

　　As the man was leaving the office, depressed, he met a clerk, who had overheard the conversation.

　　“You must not be so frank and tell the truth,”said the clerk,“no office will insure you if you speak like that. Use your imagination a little.”

　　The man went to another office and was shown into the manager's room.

　　“Well, young man, how old were your parents when they died?”

　　hello everyone!

　　This year's November 9 is fire awareness day. The theme of this activity is "enhancing the fire safety responsibility and fire safety awareness of the whole people". When it comes to fire fighting, students will naturally think of the creepy word "fire". For the primary school students in our campus, how to escape and save themselves in case of fire? To solve this problem, fire experts introduced the ten methods of escape and self rescue in case of fire in public gathering places.

　　Please listen carefully:

　　First, we should understand and be familiar with the environment. When you walk into shopping malls, hotels, restaurants, song and dance halls and other public places, you should pay attention to the location of emergency exits, emergency exits and fire extinguishers, so as to evacuate and extinguish fire in time in case of accidents. Second, evacuate quickly. Once you hear the fire alarm or realize that you are surrounded by fire, you should immediately try to evacuate.

　　Third, protect the respiratory system. Towel or napkin cloth, mask, clothes, etc. can be used to cover the mouth and nose tightly during escape, otherwise there will be the risk of poisoning and suffocation of respiratory system soft tissue burned by hot air. Fourth, evacuate from the passageway. Such as evacuation stairs, fire elevators, outdoor evacuation stairs, etc. Windows, balconies, roofs, lightning wires, downpipes, etc. can also be considered for escape.

　　Fifth, use ropes to slide. Use a strong rope or tear the curtains, sheets and bedding into strips, screw them into ropes, wet them with water, and tie them to the firm heating pipes, window frames and bedsteads. The trapped people slide one by one along the rope to the next floor or ground.

　　The sixth floor is the low floor jump off, which is applicable to the second floor. Before jumping, throw some soft items such as quilts, pillows, mattresses and coats to the ground for "soft landing", and then hold the window with your hands, droop and slide naturally, so as to shorten the jumping height.

　　Seventh, we should use equipment. Commonly used are descent device, life bag, net, air cushion, soft ladder, slide rod, slide platform, guide rope, life-saving gangway, etc.

　　8. Temporary asylum. When there is no way to escape, the toilet can be used to temporarily make it difficult. When taking refuge, spray the fire doors and windows with water to wet all combustibles in the room and prolong the time. During the period of temporary asylum, take the initiative to contact the outside world in order to be rescued as soon as possible.

　　9. Using signs to guide people out of danger. Signs such as "emergency exit", "emergency exit", "safety passage", "fire alarm telephone" and brief escape direction are set on the walls, ceilings, doors and corners of public places. The trapped people can escape in order according to the direction indicated by the signs, which can solve the "urgent need".

　　10. we should promote self-interest. We should resolutely stop the behavior of disregarding the life and death of others and the phenomenon of front hugging and back crowding. Only orderly and rapid evacuation can minimize casualties.

　　There are still a lot of common sense about fire safety. Please log in to "China fire protection network" and other relevant websites at home or with the permission of your computer teacher this week to learn more about fire safety.

　　Thank you!

　　What I'd like to do today is talk about one of my favorite subjects, and that is the neuroscience of sleep.

　　Now, there is a sound -- (Alarm clock) -- aah, it worked -- a sound that is desperately, desperately familiar to most of us, and of course it's the sound of the alarm clock. And what that truly ghastly, awful sound does is stop the single most important behavioral experience that we have, and that's sleep. If you're an average sort of person, 36 percent of your life will be spent asleep, which means that if you live to 90, then 32 years will have been spent entirely asleep.

　　Now what that 32 years is telling us is that sleep at some level is important. And yet, for most of us, we don't give sleep a second thought. We throw it away. We really just don't think about sleep. And so what I'd like to do today is change your views, change your ideas and your thoughts about sleep. And the journey that I want to take you on, we need to start by going back in time.

　　"Enjoy the honey-heavy dew of slumber." Any ideas who said that? Shakespeare's Julius Caesar. Yes, let me give you a few more quotes. "O sleep, O gentle sleep, nature's soft nurse, how have I frighted thee?" Shakespeare again, from -- I won't say it -- the Scottish play. [Correction: Henry IV, Part 2] (Laughter) From the same time: "Sleep is the golden chain that ties health and our bodies together." Extremely prophetic, by Thomas Dekker, another Elizabethan dramatist.

　　But if we jump forward 400 years, the tone about sleep changes somewhat. This is from Thomas Edison, from the beginning of the 20th century. "Sleep is a criminal waste of time and a heritage from our cave days." Bang. (Laughter) And if we also jump into the 1980s, some of you may remember that Margaret Thatcher was reported to have said, "Sleep is for wimps." And of course the infamous -- what was his name? -- the infamous Gordon Gekko from "Wall Street" said, "Money never sleeps."

　　What do we do in the 20th century about sleep? Well, of course, we use Thomas Edison's light bulb to invade the night, and we occupied the dark, and in the process of this occupation, we've treated sleep as an illness, almost. We've treated it as an enemy. At most now, I suppose, we tolerate the need for sleep, and at worst perhaps many of us think of sleep as an illness that needs some sort of a cure. And our ignorance about sleep is really quite profound.

　　Why is it? Why do we abandon sleep in our thoughts? Well, it's because you don't do anything much while you're asleep, it seems. You don't eat. You don't drink. And you don't have sex. Well, most of us anyway. And so therefore it's -- Sorry. It's a complete waste of time, right? Wrong. Actually, sleep is an incredibly important part of our biology, and neuroscientists are beginning to explain why it's so very important. So let's move to the brain.

　　Now, here we have a brain. This is donated by a social scientist, and they said they didn't know what it was, or indeed how to use it, so -- (Laughter) Sorry. So I borrowed it. I don't think they noticed. Okay. (Laughter)

　　The point I'm trying to make is that when you're asleep, this thing doesn't shut down. In fact, some areas of the brain are actually more active during the sleep state than during the wake state. The other thing that's really important about sleep is that it doesn't arise from a single structure within the brain, but is to some extent a network property, and if we flip the brain on its back -- I love this little bit of spinal cord here -- this bit here is the hypothalamus, and right under there is a whole raft of interesting structures, not least the biological clock. The biological clock tells us when it's good to be up, when it's good to be asleep, and what that structure does is interact with a whole raft of other areas within the hypothalamus, the lateral hypothalamus, the ventrolateral preoptic nuclei. All of those combine, and they send projections down to the brain stem here. The brain stem then projects forward and bathes the cortex, this wonderfully wrinkly bit over here, with neurotransmitters that keep us awake and essentially provide us with our consciousness. So sleep arises from a whole raft of different interactions within the brain, and essentially, sleep is turned on and off as a result of a range of

　　Okay. So where have we got to? We've said that sleep is complicated and it takes 32 years of our life. But what I haven't explained is what sleep is about. So why do we sleep? And it won't surprise any of you that, of course, the scientists, we don't have a consensus. There are dozens of different ideas about why we sleep, and I'm going to outline three of those.

　　The first is sort of the restoration idea, and it's somewhat intuitive. Essentially, all the stuff we've burned up during the day, we restore, we replace, we rebuild during the night. And indeed, as an explanation, it goes back to Aristotle, so that's, what, 2,300 years ago. It's gone in and out of fashion. It's fashionable at the moment because what's been shown is that within the brain, a whole raft of genes have been shown to be turned on only during sleep, and those genes are associated with restoration and metabolic pathways. So there's good evidence for the whole restoration hypothesis.

　　What about energy conservation? Again, perhaps intuitive. You essentially sleep to save calories. Now, when you do the sums, though, it doesn't really pan out. If you compare an individual who has slept at night, or stayed awake and hasn't moved very much, the energy saving of sleeping is about 110 calories a night. Now, that's the equivalent of a hot dog bun. Now, I would say that a hot dog bun is kind of a meager return for such a complicated and demanding behavior as sleep. So I'm less convinced by the energy conservation idea.

　　But the third idea I'm quite attracted to, which is brain processing and memory consolidation. What we know is that, if after you've tried to learn a task, and you sleep-deprive individuals, the ability to learn that task is smashed. It's really hugely attenuated. So sleep and memory consolidation is also very important. However, it's not just the laying down of memory and recalling it. What's turned out to be really exciting is that our ability to come up with novel solutions to complex problems is hugely enhanced by a night of sleep. In fact, it's been estimated to give us a threefold advantage. Sleeping at night enhances our creativity. And what seems to be going on is that, in the brain, those neural connections that are important, those synaptic connections that are important, are linked and strengthened, while those that are less important tend to fade away and be less important.

　　Okay. So we've had three explanations for why we might sleep, and I think the important thing to realize is that the details will vary, and it's probable we sleep for multiple different reasons. But sleep is not an indulgence. It's not some sort of thing that we can take on board rather casually. I think that sleep was once likened to an upgrade from economy to business class, you know, the equiavlent of. It's not even an upgrade from economy to first class. The critical thing to realize is that if you don't sleep, you don't fly. Essentially, you never get there, and what's extraordinary about much of our society these days is that we are desperately sleep-deprived.

　　So let's now look at sleep deprivation. Huge sectors of society are sleep-deprived, and let's look at our sleep-o-meter. So in the 1950s, good data suggests that most of us were getting around about eight hours of sleep a night. Nowadays, we sleep one and a half to two hours less every night, so we're in the six-and-a-half-hours-every-night league. For teenagers, it's worse, much worse. They need nine hours for full brain performance, and many of them, on a school night, are only getting five hours of sleep. It's simply not enough. If we think about other sectors of society, the aged, if you are aged, then your ability to sleep in a single block is somewhat disrupted, and many sleep, again, less than five hours a night. Shift work. Shift work is extraordinary, perhaps 20 percent of the working population, and the body clock does not shift to the demands of working at night. It's locked onto the same light-dark cycle as the rest of us. So when the poor old shift worker is going home to try and sleep during the day, desperately tired, the body clock is saying, "Wake up. This is the time to be awake." So the quality of sleep that you get as a night shift worker is usually very poor, again in that sort of five-hour region. And then, of course, tens of millions of people suffer from jet lag. So who here has jet lag? Well, my goodness gracious. Well, thank you very much indeed for not falling asleep, because that's what your brain is craving.

　　One of the things that the brain does is indulge in micro-sleeps, this involuntary falling asleep, and you have essentially no control over it. Now, micro-sleeps can be sort of somewhat embarrassing, but they can also be deadly. It's been estimated that 31 percent of drivers will fall asleep at the wheel at least once in their life, and in the U.S., the statistics are pretty good: 100,000 accidents on the freeway have been associated with tiredness, loss of vigilance, and falling asleep. A hundred thousand a year. It's extraordinary. At another level of terror, we dip into the tragic accidents at Chernobyl and indeed the space shuttle Challenger, which was so tragically lost. And in the investigations that followed those disasters, poor judgment as a result of extended shift work and loss of vigilance and tiredness was attributed to a big chunk of those disasters.

　　So when you're tired, and you lack sleep, you have poor memory, you have poor creativity, you have increased impulsiveness, and you have overall poor judgment. But my friends, it's so much worse than that.

　　(Laughter)

　　If you are a tired brain, the brain is craving things to wake it up. So drugs, stimulants. Caffeine represents the stimulant of choice across much of the Western world. Much of the day is fueled by caffeine, and if you're a really naughty tired brain, nicotine. And of course, you're fueling the waking state with these stimulants, and then of course it gets to 11 o'clock at night, and the brain says to itself, "Ah, well actually, I need to be asleep fairly shortly. What do we do about that when I'm feeling completely wired?" Well, of course, you then resort to alcohol. Now alcohol, short-term, you know, once or twice, to use to mildly sedate you, can be very useful. It can actually ease the sleep transition. But what you must be so aware of is that alcohol doesn't provide sleep, a biological mimic for sleep. It sedates you. So it actually harms some of the neural proccessing that's going on during memory consolidation and memory recall. So it's a short-term acute measure, but for goodness sake, don't become addicted to alcohol as a way of getting to sleep every night.

　　Another connection between loss of sleep is weight gain. If you sleep around about five hours or less every night, then you have a 50 percent likelihood of being obese. What's the connection here? Well, sleep loss seems to give rise to the release of the hormone ghrelin, the hunger hormone. Ghrelin is released. It gets to the brain. The brain says, "I need carbohydrates," and what it does is seek out carbohydrates and particularly sugars. So there's a link between tiredness and the metabolic predisposition for weight gain.

　　Stress. Tired people are massively stressed. And one of the things of stress, of course, is loss of memory, which is what I sort of just then had a little lapse of. But stress is so much more. So if you're acutely stressed, not a great problem, but it's sustained stress associated with sleep loss that's the problem. So sustained stress leads to suppressed immunity, and so tired people tend to have higher rates of overall infection, and there's some very good studies showing that shift workers, for example, have higher rates of cancer. Increased levels of stress throw glucose into the circulation. Glucose becomes a dominant part of the vasculature and essentially you become glucose intolerant. Therefore, diabetes 2. Stress increases cardiovascular disease as a result of raising blood pressure. So there's a whole raft of things associated with sleep loss that are more than just a mildly impaired brain, which is where I think most people think that sleep loss resides.

　　So at this point in the talk, this is a nice time to think, well, do you think on the whole I'm getting enough sleep? So a quick show of hands. Who feels that they're getting enough sleep here? Oh. Well, that's pretty impressive. Good. We'll talk more about that later, about what are your tips.

　　So most of us, of course, ask the question, "Well, how do I know whether I'm getting enough sleep?" Well, it's not rocket science. If you need an alarm clock to get you out of bed in the morning, if you are taking a long time to get up, if you need lots of stimulants, if you're grumpy, if you're irritable, if you're told by your work colleagues that you're looking tired and irritable, chances are you are sleep-deprived. Listen to them. Listen to yourself.

　　What do you do? Well -- and this is slightly offensive -- sleep for dummies: Make your bedroom a haven for sleep. The first critical thing is make it as dark as you possibly can, and also make it slightly cool. Very important. Actually, reduce your amount of light exposure at least half an hour before you go to bed. Light increases levels of alertness and will delay sleep. What's the last thing that most of us do before we go to bed? We stand in a massively lit bathroom looking into the mirror cleaning our teeth. It's the worst thing we can possibly do before we went to sleep. Turn off those mobile phones. Turn off those computers. Turn off all of those things that are also going to excite the brain. Try not to drink caffeine too late in the day, ideally not after lunch. Now, we've set about reducing light exposure before you go to bed, but light exposure in the morning is very good at setting the biological clock to the light-dark cycle. So seek out morning light. Basically, listen to yourself. Wind down. Do those sorts of things that you know are going to ease you off into the honey-heavy dew of slumber.

　　Okay. That's some facts. What about some myths?

　　Teenagers are lazy. No. Poor things. They have a biological predisposition to go to bed late and get up late, so give them a break.

　　We need eight hours of sleep a night. That's an average. Some people need more. Some people need less. And what you need to do is listen to your body. Do you need that much or do you need more? Simple as that.

　　Old people need less sleep. Not true. The sleep demands of the aged do not go down. Essentially, sleep fragments and becomes less robust, but sleep requirements do not go down.

　　And the fourth myth is, early to bed, early to rise makes a man healthy, wealthy and wise. Well that's wrong at so many different levels. (Laughter) There is no, no evidence that getting up early and going to bed early gives you more wealth at all. There's no difference in socioeconomic status. In my experience, the only difference between morning people and evening people is that those people that get up in the morning early are just horribly smug.

　　(Laughter) (Applause)

　　Okay. So for the last part, the last few minutes, what I want to do is change gears and talk about some really new, breaking areas of neuroscience, which is the association between mental health, mental illness and sleep disruption. We've known for 130 years that in severe mental illness, there is always, always sleep disruption, but it's been largely ignored. In the 1970s, when people started to think about this again, they said, "Yes, well, of course you have sleep disruption in schizophrenia because they're on anti-psychotics. It's the anti-psychotics causing the sleep problems," ignoring the fact that for a hundred years previously, sleep disruption had been reported before anti-psychotics.

　　So what's going on? Lots of groups, several groups are studying conditions like depression, schizophrenia and bipolar, and what's going on in terms of sleep disruption. We have a big study which we published last year on schizophrenia, and the data were quite extraordinary. In those individuals with schizophrenia, much of the time, they were awake during the night phase and then they were asleep during the day. Other groups showed no 24-hour patterns whatsoever. Their sleep was absolutely smashed. And some had no ability to regulate their sleep by the light-dark cycle. They were getting up later and later and later and later each night. It was smashed.

　　So what's going on? And the really exciting news is that mental illness and sleep are not simply associated but they are physically linked within the brain. The neural networks that predispose you to normal sleep, give you normal sleep, and those that give you normal mental health are overlapping. And what's the evidence for that? Well, genes that have been shown to be very important in the generation of normal sleep, when mutated, when changed, also predispose individuals to mental health problems. And last year, we published a study which showed that a gene that's been linked to schizophrenia, which, when mutated, also smashes the sleep. So we have evidence of a genuine mechanistic overlap between these two important systems.

　　Other work flowed from these studies. The first was that sleep disruption actually precedes certain types of mental illness, and we've shown that in those young individuals who are at high risk of developing bipolar disorder, they already have a sleep abnormality prior to any clinical diagnosis of bipolar. The other bit of data was that sleep disruption may actually exacerbate, make worse the mental illness state. My colleague Dan Freeman has used a range of agents which have stabilized sleep and reduced levels of paranoia in those individuals by 50 percent.

　　So what have we got? We've got, in these connections, some really exciting things. In terms of the neuroscience, by understanding the neuroscience of these two systems, we're really beginning to understand how both sleep and mental illness are generated and regulated within the brain. The second area is that if we can use sleep and sleep disruption as an early warning signal, then we have the chance of going in. If we know that these individuals are vulnerable, early intervention then becomes possible. And the third, which I think is the most exciting, is that we can think of the sleep centers within the brain as a new therapeutic target. Stabilize sleep in those individuals who are vulnerable, we can certainly make them healthier, but also alleviate some of the appalling symptoms of mental illness.

　　So let me just finish. What I started by saying is take sleep seriously. Our attitudes toward sleep are so very different from a pre-industrial age, when we were almost wrapped in a duvet. We used to understand intuitively the importance of sleep. And this isn't some sort of crystal-waving nonsense. This is a pragmatic response to good health. If you have good sleep, it increases your concentration, attention, decision-making, creativity, social skills, health. If you get sleep, it reduces your mood changes, your stress, your levels of anger, your impulsivity, and your tendency to drink and take drugs. And we finished by saying that an understanding of the neuroscience of sleep is really informing the way we think about some of the causes of mental illness, and indeed is providing us new ways to treat these incredibly debilitating conditions.

　　Jim Butcher, the fantasy writer, said, "Sleep is God. Go worship." And I can only recommend that you do the same.

　　Thank you for your attention.

　　(Applause)

　　1.Agree or disagree: There is nothing that young people could teach old people.

　　In ancient times, young people should never teach old people. Old people know much more than young because they have undergone many things in their life. They lead us to the right way. Sometimes, it regarded impolite for young to teach old. But that does not mean young people really have nothing to teach old people, especially in this high-developed times. Young people usually learn things fast and learn more. They always have a smart head for new things. Therefore, young people can teach the olds how to use computer and cellphone, how to dance and so on. Also, I think old people can learn younger passion and energetic for life. That will be a good thing.

　　2.Should pets be allowed in university dormitories?

　　In my opinion, by no means should pets be allowed in dormitories. To be honest, I've been thinking in my mind to have a pet in my dorm. Lovely pets will bring much joy to our daily life. But I eventually didn't do that. Why? Because it is something selfish and irresponsible. Dormitory is a place where several people live together. To a certain degree, it is a public place. We can't just comply with our own desire while ignore other roommates?feeling. Having a pet in dorm can be troublesome or even annoying. It may make the room dirty and even in a mess. What't worse, some people are allergic to certain animals. Also, people's rest can be guaranteed. Some people may say that we could choose a mild and little pet such as fishes. In this case, if your roommates don't reject, I think it is acceptable.

　　Nothing is difficult if you put your heart on it. Nothing is easy if you don’t try your best.

　　We often hear people say, "Never give up." This can be encouraging words and words of determination. A person who believes in them will keep trying to reach his goal no matter how many times he fails. In my opinion, the quality of determination to succeed is an important one to have. Therefore, I believe that we should never give up.

　　One reason is that if we give up too easily, we will rarely achieve anything. It is not unusual for us to fail in our first attempt at something new, so we should not feel discouraged and should try again. Besides, if we always give up when we fail, we will not be able to develop new skills and grow as people. Another reason we should never give up is that we can learn from our mistakes only if we make a new effort. If we do not try again, the lesson we have learned is wasted. Finally, we should never give up because as we work to reach our goals, we develop confidence, and this confidence can help us succeed in other areas of our lives.

　　Probably the greatest example of persistence is Abraham Lincoln. Born into poverty, Lincoln was faced with defeat throughout his life. He lost eight elections, twice failed in business and suffered a nervous breakdown.

　　He could have quit many times - but he didn't and because he didn't quit, he became one of the greatest presidents in the history of our country.

　　Lincoln was a champion and he never gave up.

　　In short, it is important that we don’t give up when working for our goals. Whether we succeed in the end or not, we will learn something, and what we learn will help us to become better, more confident people. Furthermore, if we give up, we have no chance of attaining our goals, but if we keep trying, there is always a chance that we will succeed one k you very much!

　　Good morning, ladies and gentlemen, I’m very glad to make a speech here. Today my topic is “I love you, China.”

　　Since the day I was born, I began to have a proud name—Chinese. Since the day I began to talk, the most beautiful sentence I’ve ever learnt has been “I love you, China!”

　　I love you, China, and I’m so proud of being a Chinese. I’m proud that I’ve got the beautiful yellow skin, black eyes and black hair. I’m also proud that I speak the most beautiful language in the world—Chinese.

　　I love you, China, for I can feel the deep love you give me every day, every minute. Last year, I got an opportunity to visit the United States of America. During my staying there, my father’s boss once invited my family to dinner. While at , he looked at me and asked: “Little boy, how long have you been in America?” “About a month,” I answered, “How lucky you are!” he said, “If you were living in China, how could you learn such perfect English?” I smiled and told him proudly that all the students in China are able to learn English at school. I saw his surprised eyes and said to myself, “I’m proud of you, China ”

　　Dear teachers and students,

　　hello everyone! Today, the topic of my speech is "cherish life, safe life".

　　I know that most of the students will sing songs such as "peace to you" and "peace to a good man's life" to pray for success and peace; I believe that students understand the thinking of life contained in the words of "peace is blessing", "peace is gold"; I am sure that all the students have expressed good wishes to their parents, relatives, classmates and friends with auspicious words such as "peace, health, happiness and smooth". Yes, safety is more important than Mount Tai. It has always been the most basic lifeline for individuals, families, collectives and society. It is also the most important guarantee line for individuals to enjoy life and collectives to maintain stability.

　　At present, there are many casualties caused by ideological, psychological and behavioral deviations among primary and secondary school students, which expose the common safety risks of current students in ideology, psychology and behavior. One by one shocking, blood and tears intertwined tragedy can not help but make people sigh, fear, but also sounded the alarm for our safety.

　　"Life", what a vivid word“ "Safety" is such an old topic“ Happiness is such a wonderful state. Students: one person is safe, the whole family is happy; Life is supreme and safety is the key; Safety first, prevention first. Only in safety can life keep its vitality forever, and only in safety can happiness have its charm forever. Safety has built our beautiful home and become a link between relatives and friends. On the issue of safety, we must not be paralyzed or lucky. On the issue of safety, we must guard against and be alert. We must be alert to thinking, comply with the rules and be cautious in action; It is necessary to establish a high sense of safety. Everyone stresses safety, always and everything; It is necessary to build a great wall of safety for thought, behavior and life.

　　Perhaps many students will think that safety only refers to the safety of the body, even the physical health and not hurt; I think as long as my body is healthy and can move freely, it is called safety. I don't think that's all about security. Even a man with a sound physique, if his moral level is low, his ability to distinguish right from wrong is not strong, and if he is confused, he has the suspicion of forming a clique and drinking; If he shows his loyalty and causes trouble, he not only likes to go with the flow, but also wants to make trouble; What this shows is the problem of ideological security. Just as in the previous week, there were several fights between classmates, as well as events on the court. Basketball game should be a game of friendship and style, but there are so many students fighting for the win and lose, which makes the relationship between students tense. It's not hard to imagine that it's very difficult to be a good person all one's life with such unsafe thoughts. In addition, if a person with a sound physique indulges in the spiritual opium of bad books and online games, and sucks every day and everywhere, he can't help but wander and think about it in class; Late at night can not help but to cross the wall bubble Internet cafes stay up all night; If he is infatuated with the sentimental feelings of young boys and girls prematurely, he will search for sorrow and hatred without any reason, be crazy and stupid, be crazy and crazy, and even be jealous and resentful, and become a beauty. This shows the safety problem of behavior. With such unsafe behavior, it is also very difficult to read a good book steadily and smoothly.

　　Whether it is personal safety, ideological safety or behavioral safety, they all have one common characteristic, that is, the cruelty of the result. Traffic accidents, swimming and drowning accidents, sports accidents, and occasional accidents of chasing and fighting during recess. The light ones can hurt the physique, and the heavy ones can endanger the life. Their consequences are cruel. However, the deformity of ideology and morality and the deviance of behavior are more terrible than the unsound physique.

　　Zang Kejia wrote in the poem some people: "some people live, but they have died." I think that those who lose their healthy spiritual pursuit, lose their right direction of life, and have a living body are the products of incomplete thinking? At best, this "product" can only be a machine that endlessly absorbs and digests the blood and sweat of parents. It can only become a waste in the long river of social development, and even a dangerous substance endangering social development.

　　Dear teachers and students, we all live in a close relationship interwoven by family affection, morality, responsibility, obligation and so on. So the individual is not just the individual. Everyone's present is connected with the future, everyone's own is connected with the family, and everyone's honor and disgrace are connected with the whole. For the growth of individuals, for the happiness of families, for the whole of honor and disgrace, let's build a great wall of safety for our thoughts, behaviors and lives, and be good people. Only good people can live a safe life; I wish a good man a safe life.

　　If I speak in the tongues of men and of angels, but have not love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but have not love, I am nothing. If I give all I possess to the poor and surrender my body to the flames, but have not love, I gain nothing.

　　Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs.

　　Love does not delight in evil but rejoices with the truth. It always protects, always trusts, always hopes, always perseveres.

　　Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away. For we know in part and we prophesy in part, but when perfection comes, the imperfect disappears. When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put childish ways behind me. Now we see but a poor reflection as in a mirror; then we shall see face to face. Now I know in part; then I shall know fully, even as I am fully known. And now these three remain: faith, hope and love. But the greatest of these is love.

　　It hurts to love someone and not be loved in return. But what is more painful is to love someone and never find the courage to let that person know how you feel.

　　A sad thing in life is when you meet someone who means a lot to you, only to find out in the end that it was never meant to be and you just have to let go.

　　The best kind of friend is the kind you can sit on a porch swing with, never say a word, and then walk away feeling like it was the best conversation you've ever had.

　　It's true that we don't know what we've got until we lose it, but it's also true that we don't know what we've been missing until it arrives.

　　It takes only a minute to get a crush on someone, an hour to like someone, and a day to love someone but it takes a lifetime to forget someone. Don't go for looks; they can deceive. Don't go for wealth, even that fades away. Go for someone who makes you smile because it takes only a smile to make a dark day seem bright.

　　Dream what you want to dream; go where you want to go; be what you want to be, because you have only one life and one chance to do all the things you want to do.

　　Always put yourself in the other's shoes. If you feel that it hurts you, it probably hurts the person too.

　　A careless word may kindle strife; a cruel word may wreck a life; a timely word may level stress; a loving word may heal and bless.

　　The happiest of people don't necessarily have the best of everything they just make the most of everything that comes along their way.

　　Love begins with a smile, grows with a kiss, ends with a tear. When you were born, you were crying and everyone around you was smiling. Live your life so that when you die, you're the one smiling and everyone around you is crying.

　　There was once a guy who suffered from cancer, a cancer that can?'t be cured. He was 18 years old and he could die anytime. All his life, he was stuck in his house being taken cared by his mother. He never went outside but he was sick of staying home and wanted to go out for once. So he asked his mother and she gave him permission.

　　He walked down his block and found a lot of stores. He passed a CD store and looked through the front door for a second as he walked. He stopped and went back to look into the store. He saw a beautiful girl about his age and he knew it was love at first sight. He opened the door and walked in, not looking at anything else but her. He walked closer and closer until he was finally at the front desk where she sat.

　　She looked up and asked, “Can I help you?”

　　She smiled and he thought it was the most beautiful smile he has ever seen before and wanted to kiss her right there.

　　He said, “Uh… Yeah… Umm… I would like to buy a CD.”

　　He picked one out and gave her money for it.

　　"Would you like me to wrap it for you?” she asked, smiling her cute smile again.

　　He nodded and she went to the back. She came back with the wrapped CD and gave it to him. He took it and walked out of the store.

　　He went home and from then on, he went to that store every day and bought a CD, and she wrapped it for him. He took the CD home and put it in his closet. He was still too shy to ask her out and he really wanted to but he couldn't. His mother found out about this and told him to just ask her. So the next day, he took all his courage and went to the store as usual. He bought a CD like he did every day and once again she went to the back of the store and came back with it wrapped. He took it and when she wasn't looking, he left his phone number on the desk and ran out…

　　One day the phone rang, and the mother picked it up and said, “Hello?”

　　It was the girl! The mother started to cry and said, “You don?'t know? He passed away yesterday…”

　　The line was quiet except for the cries of the boy's mother. Later in the day, the mother went into the boy?'s room because she wanted to remember him. She thought she would start by looking at his clothes. So she opened the closet.

　　She was face to face with piles and piles and piles of unopened CDs. She was surprised to find all these CDs and she picked one up and sat down on the bed and she started to open one. Inside, there was a CD and as she took it out of the wrapper, out fell a piece of paper. The mother picked it up and started to read it. It said: Hi… I think U R really cute. Do u wanna go out with me? Love, Jocelyn.

　　The mother was deeply moved and opened another CD…

　　Again there was a piece of paper. It said: Hi… I think U R really cute. Do u wanna go out with me? Love, Jocelyn.

　　Love is… when you?'ve had a huge fight but then decide to put aside your egos, hold hands and say, “I Love You.”

　　about six years ago i decided that i would learn arabic, which turns out to be a supremely logical language. to write a word or a phrase or a sentence in arabic is like crafting an equation, because every part is extremely precise and carries a lot of information. that's one of the reasons so much of what we've come to think of as western science and mathematics and engineering was really worked out in the first few centuries of the common era by the persians and the arabs and the turks.
