I also realize that only those who bring happiness for others can be truly happy. So I often take part in activities concerning public welfare. I once went to a barren mountain village with my classmates. We taught the kids there who could not afford school. While showing them how broad and how civilized the outer world is, I was deeply touched by their eagerness to learn, their honesty and their purity. I couldn't control my tears on the day when we left. The precious experience with the poor kids made me aware of the responsibility on the shoulders of us, future teachers.

Besides study and social practice, there are entertainments as well. I do body building every day, hoping to keep healthy and energetic. We also write a play and put it on in our spare time.

Campus life is the most splendid time. But different people have different choices. The majority of students cherish their beautiful season and cherish the hope that one day they'll become outstanding. But there are indeed some students still under ignorance. They gather together for eating, drinking or playing cards. They're busy in searching for a girlfriend or a boyfriend. They forget completely about their mission as college students and the hope of their motherland.

Finally, I do hope everybody can try their best to become a worthy citizen of the country. I do hope everybody can become the backbone of our nation and make great contributions to society!

Like a child endlessly asking, we humans, throughout history, have been continually demanding what we desire from nature. We enjoy the comfort and beauty of our furniture, yet we never bother to think about the serious soil erosion caused by deforestation. We take it for granted that we must warm ourselves in winter times, yet we seldom realize the burning away of precious natural resources. We appreciate all the prosperity from the development of modern industry, yet few would give the slightest consideration to the global air and water pollution caused by industrial wastes. Our ruthless exploitation has permanently impaired our mother earth. As we tragically learned from last summer's floods. we cannot continue our carelessness.

Finally, standing here at the threshold of the 21st century, we cannot help thinking of our posterity. Nature is not only the mother of the present generation, but also the mother of the generations to come. How severely our descendents will criticize us if we leave them a barren and lifeless mother? How much more they will appreciate us if we give them a world of harmony to inherit? Let us start respecting and caring for nature from now on. Let us start the campaign of creating a mutually beneficial relationship between people and nature right from this moment. With this new start, I firmly believe, that our children, and our children's children will live in a brand new age of green trees, clean air, crystal water, blue sky and an even more promising world!

After the arduous military training, I get absolutely absorbed in my studies. The classes given by the teachers are excellent. They provide us with information not only from our textbooks but from many other sources as well. They easily arouse my insatiable desire to take in as much as I can.

Frankly speaking, at first I had some difficulty following the teachers. However, through my own efforts and thanks to my teachers' guidance, I made remarkable progress. Now I've benefited a lot from lectures and many other academic reports.

Learning is a long process; I'll keep exploring in the treasure house of knowledge to enrich myself. This summer I got out of the ivory tower and entered the real world. A publishing house offered me a part'time job in compilation and revision.

At the beginning I was belittled by my colleagues. But they were really surprised when I translated seven English articles over 5,000 words on only one day. Gradually, they began to look at me with respectful eyes. In their opinion I turned out to be a useful and trustworthy colleague.

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 exists in 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!

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，总能表现出青春的活力„„„

一旦青春的天线倒下，你的灵魂即为玩世不恭之雪、悲观厌世之冰覆盖;即使你年方

20.其实你已垂垂老也。而只要你青春的天线高高耸起，就可以随时接收到乐观的电波-----即使你年过八旬，行将就木，而你却仍然拥有青春，你仍然年轻。

谢谢!

since the quality of honesty applies to all behaviors, one cannot refuse to consider factual information, for example, in an unbiased manner and still claim that one's knowledge, belief or position is an attempt to be truthful. such a belief is clearly a product of one's desires and simply has nothing to do with the human ability to know. basing one's positions on what one wants — rather than unbiased evidence gathering — is dishonest even when good intentions can be cited — after all even hitler could cite good intentions and intended glory for a select group of people. clearly then, an unbiased approach to the truth is a requirement of honesty.

because intentions are closely related to fairness and certainly affect the degree of honesty/dishonesty, there is a wide spread confusion about honesty--and a general belief that being dishonest means that one always correctly understands if their behavior is either honest or dishonest. self-perception of our morality is non-static and volatile. it's often at the moment we refuse to consider other perspectives that there is a clear indication we are not pursuing the truth, rather than simply and exclusively at the moment we can muster up evidence that we are right. socrates had much to say about truth, honesty and morality, and explained that if people really understood that their behavior was wrong — then they simply wouldn't do it — by definition. unfortunately, honesty in the western tradition has been marginalized to specific instances — perhaps because a thorough understanding of honesty collides with ideologies of all types. ideologies and idealism often exaggerate and suppress evidence in order to support their perspectives — at the expense of the truth. this process erodes the practice and understanding of honesty. to an ideologist the truth quite often becomes insignificant, what matters most are their ideals and what ever supports their desires to enjoy and spread those ideals.

There was a man who had seven sons, but he had no daughter, greatly though he longed for one. At last his wife told him that they could again expect a child and, sure enough, when it was born it was a baby girl. There was great rejoicing, but the child was weak and puny, so weak that it had to be christened at once. The father told one of the boys to go quickly to the spring and fetch christening water; the other six ran along with him, and because each of them wanted to be the first to dip the jug into the well, it fell in and sank. So there they stood and didn't know what to do, and none of them dared go home. When they didn't come back their father got impatient and said:" I'll wager they've been playing some game again and forgotten all about it, the godless brats." He was afraid the little girl would have to die unbaptized, and in his rage he cried out:" I wish those boys would all turn into ravens." He'd scarcely spoken the words when he heard a whirring of wings in the air overhead, looked up and saw seven coal-black ravens flying away.

The environment of the world has been damaged by the human beings for so many years without much recent years,however,more and more nations have begun to preserve the environment as they have realized the importance of it.

The nature has given us so much,but look at what we have done in return for its sands upon thousands of trees have been cut down,including some precious species. Numerous rivers and lakes have been drained only to set up modern buildings. Priceless wildlife has turned into delicious dishes on the air is being befouled by the smoke from the chimneys of the plants...

All this irritates the nature ,which results in the shortage of valuable resources,air pollution,countless acres of lands becoming deserts,unately,many countries have got to know the seriousness of the problem and take active measures to preserve the sincerely hope that all the peo;le in the world willtake part in the campaign and join hands to protect the nature.

dear teacher, dear students:

hello everybody!

my topic today is "making the self-confidence."

thomas edison once said: "confidence is the first secret of success." yes, in life, we can not do without self-confidence everywhere. a person without faith, is bound to be abandoned by the society of a person, a person has been abandoned by successful, one was abandoned by the people themselves! therefore, we can say without hesitation: self-confidence is a person's soul!

self-confidence does not equal arrogance. it is a determination, has the power over life and death. never blindly self-confidence, it is hard honing the ability of the condensed. ability is like the crown, it is only mounted on a self-confident fengyun sparkling diamonds, will become eye-catching and gorgeous. similarly, there is no ability to foil, and let confidence no matter how brilliant, but also like the loss of green flowers, value greatly reduced.

i believe we all heard of "with confidence" the idiom story! good at the northern song painter painting paper with bamboo, when pen to paper without thinking each time they claimed a life-like bamboo map. how did he do it? it turned out that his daily observation of the bamboo hut, seasons, his unshakeable. over time, the length of bamboo thickness, leaf shape color, he is familiar with the heart, naturally, put the bamboo painted superb.

this is the power of self-confidence!

good morning everybody. it is true that most of us value honesty highly. however, nowadays we often confront confidence crisis such as cheating, overcharging, fake commodities and so on. i think that we should be honest because being honest is not only beneficial to ourselves but also to others and the whole society. the reasons can be listed as tly, only honest people can be truly respected by the others and can make more friends over a long period of time.

secondly, honesty, which is the traditional virtue of the chinese people, can make our life easier and more harmonious. thirdly, honesty can make our society more stable. a case in point is that singapore, a society featuring trustworthiness and integrity, has a comparatively low criminal rate.

responsbility can be understood in many ways. for the parents , they have had the responsibility for caring for and fostering their children since the birth of their teachers,both in kindergartens and colleges,they also should be responsible for the study and life of their students,that is to say,teahers are the second parents of children somewhile.

for us,as a friend of others,it is our responsibility to help our friends when they are in trouble or faced with difficulties. each one has the different responsibily based on their roles but we must take it for granted that we are responsible for the society.

that is all ,thank you .

学习如何说不

我们都被教导说，我们应该要帮助别人。这是应该做的事，而且这样做会使我们受人欢迎。它甚至会为我们赢得一些回报。但是，我们必须要实际一点。我们不能答应每一个要求。如果我们这么做，我们就一定会失败或发疯。有时候我们确实没有时间去帮忙。既然如此，我们就必须知道如何有礼貌地说不。

当我们需要说不的时候，有个办法我们可以试试。首先，我们应该要说实话。假如我们真的办不到某件事，我们就应该说不。第二，我们应该记得要客气地拒绝对方的要求。我们必须清楚地表达，但态度也必须真诚并且表示同情。一个真正的朋友会谅解的。最后，我们不必为了说不而觉得有罪恶感。有时候拒绝别人才是我们应该做的事。它可以替我们自己和别人，都省下许多麻烦。总而言之，我们无法一直取悦每个人。拒绝请求是人生的一部分。

Why does football get people into a frenzy?

Who is your idol? It may be Napoleon, Picasso, or Michael Jackson. But who is my idol? Can you guess? It is Ronaldo. He is the No. 1 super star of football.

Football is a game in which 22 people chase one ball around a large field. The aim of the game is to get the ball into the net to score.

After all, it’s such an easy game, and yet people go crazy mad over it. The answer lies in two facts. One is the game itself. Sometimes it is beyond any description. Football is a game of passes and techniques, passion and love, more importantly, unity is the key---the whole team working as one, united they will never be defeated.

The European’s style. of play is like a Waltz, the Brazilian like a Samba, and the passionate Argentineans play as if they are doing a Tango. Football is so unpredictable, so unbelievable. You will never know who will win until the last minute. Especially when suddenly there is a goal, the fans who have been sitting on the edge of their seats, will be wild with joy and excitement; and the losers with disappointed hearts will despair over their teams.

The other is of course the super stars. Each one has his own personality, just like my idol Ronaldo. When he smiles, we all smile with him. Who can forget that buck-toothed smile, or that unique hairstyle. during the 20xx World Cup. Ronaldo was born to a poor family. He has set an example to children who can’t afford a pair of shoes, but have talent and a passion for football. He gives them confidence and hope of a better future.

Football is the game that wins everyone’s heart and the best game ever invented.

Soy food good for women

Women who ate soy regularly as children have a lower risk of breast cancer, American researchers report. And men who eat fish several times a week have a lower risk of colon cancer, a second team of researchers have told the American Association for Cancer Research.

The studies add to a growing body of evidence about the role of diet in cancer. Cancer experts now believe that up to two-thirds of all cancers come from lifestyle factors such as smoking, diet and lack of exercise.

The US National Cancer Institute and researchers at the University of Hawaii found that women who ate the most soy-based foods, such as tofu and miso, when aged 5 to 11, reduced their risk of developing breast cancer by 58 per cent. It was not clear how soy might prevent cancer, though compounds in soy called isoflavones have estrogen-like effects.

A second study showed that men who ate fish at least five times a week had a 40 per cent lower risk of developing colorectal cancer compared with men who ate fish less than once a week.

Many kinds of fish are rich in omega-3 fatty acids, which interfere with the cyclooxygenase-2 or COX-2 enzyme. COX-2 affects inflammation, which may play a role in tumour growth.

据美国研究人员报告，儿童时期经常吃豆类食品的女性患乳腺癌的风险较小。另一组研究人员则向美国癌症研究协会提出，一周吃几次鱼的男性患结肠癌的几率较小。

这两项研究进一步证明了饮食对于防癌的作用。癌症防治专家认为，在所有种类的癌症中，多达三分之二都是由吸烟、节食及缺乏锻炼等不健康的生活方式造成的。

美国全国癌症研究所和夏威夷大学的研究人员发现，在5岁至11岁时经常吃豆腐、味噌等豆类食品的女性患乳腺癌的几率要低58%。至于豆类食品为什么可以防癌还不清楚，不过大豆中所含的名叫异黄酮的化合物具有雌性激素的作用。

另一项研究表明，一周吃鱼至少五次的男性患结肠癌的风险要比那些一周都吃不到一次鱼的男性低40%。很多鱼类中所富含的Omega-3脂肪酸能够抑制环氧化酶2的活性。环氧化酶2会引起发炎，这可能会刺激肿瘤的生长。

a window is opened up at the crack of dawn, beside which one man is overlooking the the mess of buildings outside, breathing the fresh air cosily. but just after a little while, he steps to his seat, staring at the computer screen till the night. this man is very likely a programmer.

there is a man who concentrates on his computer, but doesn’t care about however he dresses, or even whether he washes his face. there is a man who has a good knowledge of computer language, but has a low eq and makes a bad relationship with others.

there is a man who stays at home and does his own work by himself day and night, but just has few friends.

these images shown above probably are what people think of

programmers as, in fact, programmers indeed give us a bad impression sometimes. however, people just have a partial understanding of programmers’ life, not to mention that they can know the fun of programming. there is no doubt that programs affect all aspects of our lives in an obvious or potential way, especially they are reflected in electronic products that we use nowadays.

when you are so proud of possessing an iphone, you’d better

remember that it is the program that makes you get confidence to show off the advanced mobile phones thoroughly.

when you take advantage of computers to cope with problems in life, you’d better remember that it is the program that makes you seek the convenience of computer.

when you needn’t worry about hot summer and cold winter owing to an air-conditioner, you’d better remember that it is the program that makes you share the machine’s intelligent.

when you release your pressure by playing varies of online games, you’d better remember that it is the program that makes you enjoy the great entertainment in life.

as people’s thoughts control their bodies, computer programs play a leading role in the modern times. both social progress and human evolution depend on the computer programs. in the practical application, a software consists of different programs and then

combines with hardware to develop into a high-tech electronic product. there are many kinds of electronic products found everywhere in our daily life. nearly all the time do we make use of these products to conduct our passion.

yes, it is definitely right that programming is a hard work because of its special characteristics---complicated, time-wasted,

logical. to make a program needs our continual patient and confidence, and we should accept failure again and again in most cases. but once you go into further understanding of computer programs, you will be surprised at the programs’ wander. in detail, through programming a heap of date or a computing model can be easily solved we expected, such as a number wanted, or the model’s parameters. the magical power of program appeals to all the programmers, certainly including me.

it is of great convenience for us to simplify or model our complex questions by programming. furthermore, studying and using programs can enforce us to form our ability of analyzing and logic.
