Ladies and gentlemen, tonight we will share the topic of science and technology and life. In today's society, everyday life is inseparable from science and technology. Science and technology are everywhere, food, clothing, housing and transportation, everything. But we can not help but ask, if we leave science and technology, or one day, science and technology are out of the control of human beings, such as artificial intelligence, can our life remain stable?

Everyone wants to maintain good health, if you are healthy, then you can do you want to do anything, your family will be full of laughter, your work will be much more simple. You want to have a healthy body? Then try to do the following thing! First, you face daily smile, maintain a good mood. Take part in some sports, such as running，playing baseball. It is in a strong body. Secondly, we must pay attention to our diet, not to drink too much wine, water, every day at least eight cups of water; Deliberately not to lose weight, did you have no health benefits. Again, resulting from smoking on your own and other people is not good! To maintain good health let us do it. Others can take away our money, house, car, or even our clothes and we can survive. But if our health was taken away, we would surely die. That is why we always try to eat in a healthy way and exercise regularly. Living a long life may be a lot easier than you think. And there are some bad habit we need to get rid of 。
A report suggests 10 steps to a longer and healthier life. 1. Shun cigarette smoke, separate yourself from smokers. . Become a nag and tell anyone you know who smokes to stop. 2. Keep moving. The U. S. Department of Health and Human Services suggests every adult get at least 150 minutes of moderate aerobic activity a week. Sessions should be at least 10 minutes long. 3. Eat like an Aegean. Follow the Mediterranean diet pattern of mostly plant foods, limiting animal protein to fish and poultry, using olive oil as the principal fat and use wine in moderation. 4. Mind your body mass index. Obesity increases the risk of diabetes 20 times and substantially boosts the risk of developing high blood pressure, heart disease, stroke and gallstones. 5. Lift a glass, but only one. Alcohol's effects become more insidious as women age because the body's water-to-fat ratio declines over the years. 6. Don't run up a sleep debt. Medical evidence suggests we need seven to nine hours of sleep daily, but more than 60 percent of women regularly fall short of that goal. 7. Be your own best advocate on health issues. 8. Keep connected. Older women who remain socially active live longer and healthier lives than their solitary counterparts 9. Avoid stress. Find techniques to reduce stress and its effects. 10. Use supplements selectively. Experts agree the best way to get nutrients is through food. Only calcium and vitamin D, essential in preserving bone density, are recommended supplements. And that includes 1,200 mg of calcium and 1,000 mg of vitamin.

Such things always hurt our feelings.Parents may bring us pains, too. We think they don't understand us. They forbid us to do what interests us and force us to do what we hate. They keep telling us what to do and what not to do as is we knew noting. They don't really care what is in our mind.Later, some may suffer pains of losing love, pains of working and then of suppoting a family.Growing up seems to mean endless pains,.

We can do nothing but stand up and overcome them, even enjoy them and shoulder our responsibilities.My dear classmates, don't be afraid of growing up! Don't be afraid of pains. No pains, no gains.

跪求：三分钟英语演讲稿
环保问题: (1) As is apparently revealed in the pie charts above, forty-eight percent of people surveyed have never heard of the International No Motor Vehicle Day while fifty-seven percent are willing to give up driving on such a day. What is betrayed in the pie charts is most thought-provoking. The implied meaning of the pie charts is both disappointing and exciting. On the one hand, much necessary work still needs to be done with respect to environmental protection. The public ignorance of relevant environmental protection results from inadequate and limited popularity of environmental protection knowledge by relevant government departments at different levels. Since environmental protection is an international issue, we must constantly introduce the advanced and practical practice in other countries to our general public. Only in this way can we promote environmental protection in China. On the other hand, the enhancement of the public awareness of environmental protection is a welcome development. Over the past years, as people’s living standard improves, people attach more importance to the quality of their life. They have a better understanding of the relationship between environment and their daily life. As a result, they are more interested in following positive international models. In sum, we have got a mixed feeling toward the very fact revealed in the pie charts. In my view, necessary measures should be immediately taken to ensure a nice environment. First of all, government departments at all levels must play a more active role in popularizing international experience and practice of environmental protection. What’s more, the general public should be encouraged to participate more actively in environmental protection. Only in this way can we live in a healthy and harmonious environment.

(3)打好环保比赛、创建绿色北京 尽管2008北京奥运会离我们还有3年之遥，但有一项规模宏大的特殊比赛已经拉开了序幕。
这场比赛的参加者并非来自世界各国的体育选手，而是身处北京的每一位公民，比赛的场所就是我们身边的街区小巷。
我想大家已经想到了我所说的这项特殊比赛，这就是创建绿色北京、保护美好环境。
那么在这场环保大赛中，我们究竟要与谁一比高低
是繁华现代的洛杉矶、风光迷人的悉尼、还是古老神奇的雅典
都不是
比赛的对手就是我们自己，就是我们自身淡漠的环保意识。
几年前有幸在美国加州度过的一段时光，既让我享受了那里宜人的环境，更让我领略了当地人民高度的环保意识。
每当说到城市环保，我的眼前总会浮现出加州那蔚蓝的天空、明媚的阳光、碧绿的草地以及嬉戏在树枝间的松鼠、彩蝶和百灵鸟。
记得刚到美国时，常去爸爸工作的美国地质调查局玩耍，每次均能看到许多人骑自行车上下班，而其中一位满头白发的骑车老人，引起了我的好奇。
我问爸爸，那个爷爷为什么总骑车上班，是不是没钱买车
爸爸笑道：没钱买车
嘿，说出来吓死你，他可是世界上顶级的大科学家。
要论钱，他可以买一个车队呢。
那他咋不买车呢
骑车多累呀
他有车，但平时除非下雨或购物，一般不去开。
在美国有许多人都是环保主义者，为了节约能源和减少汽车尾气对大气的污染，他们用实际行动倡导人们尽量少开车。
而我们所居住的这座美国城市，还特别将每年的5月19日定成了'骑车上班日'，以支持和宣传这种有效的环保行为。
后来，我还在经常的搭车出行中获知了他们的另一件环保趣事：在美国的许多州，政府为了鼓励大家多坐公交车或几人合用一辆车，以节省能源和缓解交通压力，在城市内一些主干道路上开辟有专门的'钻石车道'，只有乘坐了二人或二人以上的车辆才从此通过。
美国人民这种自觉的环保意识和政府有效的环保措施使我从内心对他们充满了敬佩。
并深刻地影响了我的环保理念。
回国后，常常有人问我：美国好吗
我总会脱口而出：确实好
最好的是环境。
说句真心话，回国三、四年，美国那边同学和老师的面孔已经逐渐模糊，但加州那宜人的自然环境，却每每清晰地浮现在我的眼前，成为我最深的记忆和期盼故地重游的缘由，也成了我心目中北京环境的蓝图。
2008奥运会为我们倡导和实施北京的环保提供了契机，北京能否有朝一日也拥有象加州那样美丽的环境
答案是肯定的。
但需要我们以真正的环保之心和切实的环保行动去一步一步地实现。
从现在开始，如果每一位有车的朋友一星期可以少开一、两次车，每个让家长用车接送的同学一周能主动让家长少接送一两趟而改乘公车或骑自行车，我们就会有拥有更多的蓝天……。
只要我们每一位北京市民都能够自觉的从身边的环保小事做起，加州的蓝天、白云和绿草地就会在北京安家，美国的松鼠、彩蝶和百灵鸟就会来北京落户。
涓涓细流可以汇成滔滔江海，片片绿叶能够造就莽莽森林。
只要我们每一位北京市民都拿起手中的环保之笔，在我们所处的街头巷尾，为北京这幅美丽而古老的画卷添上自己的一抹绿色，就能使北京掩映在绿色的海洋中。
让我们一起行动起来，用我们集体的力量来打赢这场环保之赛，向全世界展现一块最大的金牌，这就是绿色北京、精彩奥运。
Win Competition of Environment Protection for Beijing Although the 2008 Olympics are still three years away, another special competition has already started in Beijing. This time, the competitors are not the athletes from all over the world, but the people living in Beijing. The special competition is not held in a stadium, but in every street and every corner of Beijing. I suppose some of you may have already guessed what the special competition is. Yes, it is the competition of protecting our environment and creating a green Beijing for the 2008 Olympic Games. Someone may ask who is our rival in this competition? The modern Los Angeles, the charming Sydney, or the historic Athens? No, none of them. The real rival is ourselves. It is our bad habits of neglecting to protect environment in our daily life. Several years ago, I was very lucky to have an opportunity to live in the United States for about two years. I not only enjoyed the beautiful environment there, but also appreciated the American people's active way of protecting their environment. Now, whenever the environment protection is mentioned, a beautiful view of California will arise in my mind: white clouds flying across the blue sky, green grassplot sprinkled with colorful flowers and small animals playing happily among the trees. I remember that at the beginning of my coming to America, I often went to my father's working place, the United States Geological Survey, to have fun. Each time I found a lot of people riding bicycles to their offices. Among the cyclists, an old man with white hair attracted my attention. Curiously, I asked my father, Why does the old man ride his bike to work every day? Doesn't he have enough money to buy a car? Father laughed, No, not because of money. Actually, he is one of the greatest scientists in the world. He can afford to buy a motorcade if he likes. He is just an environmentalist and usually doesn't drive unless going shopping, or in bad weather. In America, there are a lot of environmentalists, who actively protect their environment. For example, in Palo Alto city we are living now, there is even a bicycle-to-work day on May 19th every year to encourage people to decrease air pollution caused by cars. Later, I also learnt another interesting fact of environment protection there. In some states of America, in order to decrease air pollution, save energy and reduce traffic jams, state governments encourage people to take buses to work or to share a car among several people. They even set special diamond lanes in some main streets, which are only for the vehicles with 2 or more people. The positive actions of American people and the effective measures the American government takes in environment protection fully won my respects and deeply affected my consciousness in environment protection. When I was back in China, people often asked me: What do you think of America? I always bolt out: Wonderful, especially the beautiful environment. Frankly speaking, after several years, the faces of my American teachers and friends have gradually faded away from my mind, but the blue sky, green grass and lovely animals in California often arise in my mind, and became my dream of visiting there again. The 2008 Olympics provide us with the opportunity to publicize and practise environment protection in Beijing. Is it possible for Beijing to Is it possible for Beijing to become as beautiful as California? The answer is yes, but the dream needs every Beijing citizen's full support and active moves to accomplish. From now on, if every student who is driven to school can take bus or ride bicycle to school once a week, if every car owner goes to work in a car pool once a week, we can make a difference. If everyone can actively protect the environment in our daily life, the blue sky, green grass and lovely animals in California will appear in Beijing. Tiny streams can combine into a vast ocean, small trees can together be an immense forest. Beijing is often described as a beautiful and aged picture. If every Beijing citizen adds a trait of green on the picture, the whole Beijing will become an ocean of green. Let us unite together to win the competition of environment protection in Beijing, and present the world a big gold medal. That is Green Beijing, Great Olympics
三分钟的英语演讲稿
Ladies and Gentlemen , Good afternoon! I’m very glad to stand here and give you a short speech. today my topic is “youth”. I hope you will like it , and found the importance in your youth so that more cherish it. First I want to ask you some questions: 1、 Do you know what is youth? 2、 How do you master your youth? Youth Youth is not a time of life, it is a state of mind ; it is not rosy cheeks , red lips and supple knees, it is a matter of the emotions : it is the freshness ; it is the freshness of the deep springs of life .Youth means a temperamental predominance of courage over timidity of the appetite , for adventure over the love of ease. This often existsin a man of 60 more than a boy of 20 . Nobody grows old merely by a number of years . We grow old by deserting our ideals. Years wrinkle the skin , but to give up enthusiasm wrinkles the soul .Worry , fear , self –distrust bows the heart and turns the spirit back to dust . Whether 60 of 16 , there is in every human being ‘s heart the lure of wonders, the unfailing childlike appetite of what’s next and the joy of the game of living . In the center of your heart and my heart there’s a wireless station : so long as it receives messages of beauty , hope ,cheer, courage and power from men and from the infinite, so long as you are young . When the aerials are down , and your spirit is covered with snows of cynicism and the ice of pessimism, then you are grown old ,even at 20 , but as long as your aerials are up ,to catch waves of optimism , there is hope you may die young at 80. Thank you! 大学生英语演讲稿八译文 青春 青春不是指岁月，而是指心态。
粉嫩的脸，红润的唇，矫健的膝并不是青春。
青春表现在意志的坚强与懦弱。
想象的丰富与苍白、情感的充沛与贫乏等方面。
青春是生命深处清泉的喷涌。
青春是追求。
只有当勇气盖过怯弱、进取压倒苟安之时，青春才存在。
果如此，则60见之长者比20岁之少年更具青春活力。
仅仅岁月的流逝并不能使他们衰老。
而一旦抛弃理想和信念，则垂垂老也。
岁月只能使皮肤起皱。
而一旦丧失生活的激情，则连灵魂枯老，使人生枯如死水，毫无活力。
60岁长者也好，16岁少年也罢，每个人的内心深处都渴望奇迹，都如孩子一般眨着期待的双眼，期待着下一次，期待着生活的情趣，你我灵魂深处都有一座无线电中转站------只有你我年轻，则总能听到希望的呼唤，总能发出喜悦的欢呼，总能传达勇气的讯号，总能表现出青春的
急~
