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。
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.
Good morning, my dear teachers and friends! My name is Li Binge, from class four O five. Today, I am very happy to be here. My topic is “Our School”.
My dear friends, welcome to our school! My school is very beautiful! It has a big playground. We can play and do some sports there. Near the playground, there is a garden. Many trees and flowers are there. So the air is very clean and we can hear birds singing in the trees. It is so wonderful. Our teaching buildings are around the garden and look like our teachers’ arms to welcome us. We can draw pictures in the art room on the first floor and read story-books in the library on the second floor. My classroom is on the third floor. It is clean and bright. We like to study in it. The computer room is on the fifth floor. We can sing and dance in the music room on the sixth floor. What a lot of fun! We can have lunch in the canteen near Defang Teaching Building.
In our school, our teachers work hard and help us with our lessons. We study hard and listen to teachers carefully. After class, our teachers play with us and we feel very happy.
Our school is so nice and our teachers are so kind. We all love them. Dear friends, do you like them?That's all. Thanks!
Ladies and Gentlemen, Good morning! I’m very glad to stand here and give you a short speech.
Man’s life is a process of growing up, actually I’m standing here is a growth. If a person’s life must constituted by various choices, then I grow up along with these choices. Once I hope I can study in a college in future, however that’s passed, as you know I come here, now I wonder what the future holds for me.
When I come to this school, I told to myself: this my near future, all starts here. Following I will learn to become a man, a integrated man, who has a fine body, can take on important task, has independent thought, an open mind, intensive thought, has the ability to judge right and wrong, has a perfect job.
Once my teacher said :” you are not sewing, you are stylist; never forget which you should lay out to people is your thought, not craft.” I will put my personality with my interest and ability into my study, during these process I will combine learning with doing. If I can achieve this “future”, I think that I really grow up. And I deeply believe kindred, good-fellowship and love will perfection and happy in the future.
How to say future? Maybe it’s a nice wish. Lets make up our minds, stick to it and surely well enjoy our life.
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!
good morning,dear teacher and my friends.
it’s a very intresting topic today.
i think my dad was a hero for me when i was a young child. we'd go fishing, walks, and other fun things for a kid.
every child has a good and great father, and so do i. my dad played a very important role in my daily life`````exactly speaking, in my past 16 years.
my father always stands in the center of my life， from past till now and possibly in the future.
my family was rather poor when i was in my childhood. we didn't have our own house and had to live in a shabby， small room rented from my father's factory. the room was so small that there was little space for people to walk. i didn't have my own bed and had to sleep with my parents. this is terrible both for my parents and me.
but father made this all different!he works very hard on his own business, now we have our own 2 housese,surly,i have my own he take our family so much happiness, richer and richer.
when i was little, i did everything with my dad. you could always find me sitting on his knee or walking and doing everything with him. every night he would read me a bed time story and make the voices of each character.
i learnt a lot from my daddy. i learnt to never take things to seriously and to always smile.
like many other fathers, my dad and i also has generation gap. he is not good at or even can’t work the computer. so when i sitting at the computer desk,he will say something like ‘you should pay more attention to your study’, ‘don’t waste time on the computer英语演讲稿2分钟games’ , ‘it will be bad for your eyes’ and so on. how can i- a computer fan – reduce time on computer? so i continue studying and playing on it
years pasted, my father is over 45 now. it is time for me to look after him and i am sure i will do and we will live an even better life. and i will say,i really love you dad,cause you are the hero in my mind.
thank you so much!
the footsteps of the world expo is getting closer and closer to us, civilized and harmonious call is still ringing in my ears. shanghai, china obtained the right to host the world expo , expo shanghai china will be a world event, the development of shanghai's new round of golden opportunity, as it is an important embodiment of our national spirit.
world expo is a great influence and a long history of international activities, is the largest gathering of human beings. people from around the world gathered in one place display their products and skills, boast of their hometown and motherland. expo set the culmination of human civilization, which has a unique appeal, make you feel surging.
world expo is a platform, we are the masters. she put up a platform for us to let the world know us; she built a bridge for us, so we better communicate with the world. this platform may let us display self wantonly. we are the masters here, we have to landlord, let guest experience enthusiasm and happiness.
Blue Planet
We all have a common home. She provides us with enough food, enough water and enough living room. We get everything from the nature to live better, but we donnot do anything to protect her. How the air is polluted; the earth is poisoned; water is unsafe to drink and rubbish is burying the civilization that man owns.
Our environment is being polluted faster than nature and man's present efforts can prevent. Time is bringing us more people, and more people will bring us more industry. So many trees will be cut down, and more large cities will be set up. Lots of waste material, in return, is produced and harms the environment. So some experts declare that the balance of nature is being upset, so that the very survival of man is in danger.
How can we solve this problem? The answer is that we must control the speed of growing people, forbid everyone to cut down trees and pour waste water into rivers and so on.
If we achieve this, the environment will turn very clean, and our future will be full of happiness.

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.
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!
Good morning everyone!
My name is Jie Lidi. Today, my topic is: “Confidence”. As we all know, failure is the mother of success. But What I want to say is that success is the child of confidence. Without confidence, things can become negative and uncomfortable. I remember, during an English class, I wanted to make a sentence using the word "listen". I should have said: "I listen to the Voice of America" but I was too nervous and said "I listen to the Noise of America". Everybody in the class laughed. Since then I wanted to train myself to be confident. Now, confidence makes me brave and courageous. Take this speech for example. I wanted to enter this competition, but I would feel very embarrassed if I made mistakes. Just then, I thought about my dream. My dream is to become a scientist when I grow up. If I am not confident, how can I overcome difficulties I face? If I am not confident, how can I succeed in developing myself in the future? I will do it! Today, I am making a speech in public and I feel proud and confident!
I am sure, in the future, with confidence, I will go forward-always forward. Confidence will make my dreams come true!
Thank you!
