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.
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校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校
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。

scale, researchers warned, suggesting overweight people tend to score more poorly on tests of memory than their thinner peers do.
the findings suggest that a heavier weight in middle age may mean a higher risk of dementia later in life.
reporting in the journal neurology, the researchers speculated that higher rates of cardiovascular disease or diabetes might help explain the link. but its also possible that substances produced by fat cells, such as the hormone leptin, have direct effects on the brain.
measurement of weight in relation to height used to define overweight and obesity. a bmi of 25 or more indicates overweight, and 30 or more is obese.
the study also investigated the relationships between bmi and cognitive function in 2,223 healthy men and women between the ages of 32 and 62 in france through the use of four cognitive tests.
the study found a higher bmi was associated with lower cognitive test scores. results from a test involving word memory recall show people with a bmi of 20 remembered an average of nine out of 16 words, while people with a bmi of 30 remembered an average of seven out of 16 words.
研究人员提醒，如果你已步入中年，发现自己的记忆力不如从前，那么你得小心体重了。研究表明，超重的人记忆测试的得分要比较瘦的人低。
研究发现，体重偏大的中年人今后患老年痴呆症的可能性较大。
研究报告在《神经学》期刊上发表，研究人员推断，心血管疾病及糖尿病的高发现象可以解释其中的原因。此外，脂肪细胞所产生的物质，如瘦体激素，对大脑有直接影响。 此项研究将调查对象的智力与体重指数进行了对比。体重指数指的是身高和体重之间的比例，主要用来衡量一个人是否偏胖或肥胖。体重指数为25或25以上的人偏胖，达到30或30以上的人则为肥胖。
研究人员还对体重指数和认知功能间的关系进行了研究，他们在法国对2223位年龄在32岁至62岁间的健康男女进行了认知测试。
研究发现，体重指数越大，认知测试的得分越低。其中一项单词记忆的测试结果表明，在16个单词中，体重指数为20的人平均能记住9个，而体重指数为30的人平均只能记住7个。
people who do not get enough sleep are more than twice as likely to die of heart disease, according to a large british study released monday.
although the reasons are unclear, researchers said lack of sleep appeared to be linked to increased blood pressure, which is known to raise the risk of heart attacks and stroke.
a 17-year analysis of 10,000 government workers showed those who cut their sleep from seven hours a night to five or lefaced a 1.7-fold increased risk of death from all causes and more than double the risk of cardiovascular death.
the findings highlight a danger in busy modern lifestyles, francesco cappuccio, professor of cardiovascular medicine at the university of
warwicks medical school, told the annual conference of the british sleep society in cambridge.
a third of the population of the uk and over 40 percent in the us regularly sleep lethan five hours a night, so it is not a trivial problem, he told reporters.
previous research has highlighted the potential health risks of shift work and disrupted sleep. but the study by cappuccio and colleagues, which was
supported by british government and us funding, is the first to link duration of sleep and mortality rates.
the study looked at sleep patterns of participants aged 35-55 at two points in their lives - 1985-88 and 1992-93 - and then tracked their mortality rates until 2004. the results were adjusted to take account of other possible risk factors such as initial age, sex, smoking and alcohol consumption, body maindex, blood pressure and cholesterol.
cappuccio said it was possible that longer sleeping could be related to other health problems such as depression or cancer-related fatigue.
in terms of prevention, our findings indicate that consistently sleeping around seven hours per night is optimal for health, he said.
(agencies) 本周一公布的一项大规模英国调查表明，睡眠不足的人死于心脏病的几率是睡眠充足者的两倍多。
目前其中的原因尚不清楚，但研究人员称，睡眠不足会导致血压升高，从而增大患心脏病和中风的风险。
一项针对1万名政府职员、长达17年的跟踪调查表明，每晚睡眠时间从七个小时减少到五个小时或更少的人因各种原因而死亡的几率是睡眠正常者的1.7倍，而且死于心血管疾病的风险也增加了1倍多。
沃里克大学医学院的心血管药物学教授弗朗西斯哥?卡普西奥在英国睡眠学会在剑桥召开的一年一度的研讨会上说，这一研究成果揭示了忙碌的现代生活中潜在的危险。
他在接受记者采访时说：“三分之一的英国人以及超过40%的美国人每晚的睡眠时间常常达不到五个小时，所以这个问题不可小视。”
此前有调查发现轮班及睡眠中断会对健康产生潜在威胁。但卡普西奥及其同事的这项调查则首次揭示了睡眠时间长短与死亡率之间的关系。该调查由英国政府和美国基金提供资助。 该调查对年龄在35岁至55岁之间的人在1985年至1988年以及1992年至1993年两个阶段的睡眠模式进行了探究，并对这一人群截至2004年的死亡率进行了追踪。
调查还考虑到了调查对象的初始年龄、性别、是否吸烟喝酒、体重指数、血压及胆固醇指标等其它可能的风险因素。
卡普西奥说，睡眠时间过长也可能导致如抑郁症及癌因性疲乏等其它健康问题。他说：“就预防而言，我们的研究结果表明，每晚睡眠时间持续保持在七小时左右最益于身体健康。

i believe in our future
honorable judges, fellow students:
good afternoon!
recently, ther is a heated debate in our society. the college students are the beneficiaries of a rare privilege, who receive exceptional education at
extraordinary places. but will we be able to face the challenge and support ourselves against all odds? will we be able to better the lives of others? will we be able to accept the responsibility of building the future of our country?
the cynics say we care for nothing other than grades; and we neglect the need for character cultivation. but again, the cynics are wrong. we care deeply for each other, we cherish freedom, we treasure justice, and we seek truth. last week, thousands of my fellow students had their blood type tested in order to make a contribution for the children who suffer from blood cancer.
as college students, we are adolescents at the critical turning point in our lives. we all face a fundamental choice: cynicism or faith, each will profoundly impact our future, or even the future of our country. i believe in all my fellow classmates. though we are still inexperienced and even a little bit childish. i believe that we have the courage and faith to meet any challenge and take on our responsibilities. we are preparing to assume new responsibilities and tasks, and to use the education we have received to make our world a better place. i believein our future. 我对未来充满信心
尊敬的评委，各位同学：
下午好！
最近，社会上有一场很激烈的争论。大学生是一种稀有特权的享有者，在很棒的地方接受高
等教育。但是，我们能面对挑战而无所畏惧吗？我们能够改善他人的生活吗？我们能够承担建设祖国未来的重任吗？
怀疑论者说大学生是被宠坏的一代，一丁点挫折都受不了。但是他们错了，我所看到的大学生正在努力的学习独立生活。我们互相帮助打扫卫生，一起上街砍价购物，一起参加兼职工作来赚零花钱。
怀疑论者说我们除了成绩什么都不关心，从而忽略了性格的培养。但是，他们又错了。我们彼此关心，我们向往自由，我们珍惜公正，我们追求真理。上个星期，很多我的同学去验血，为了给患血癌的孩子贡献自己的力量。
作为大学生，我们是处在人生分水岭的青年。我们都面临一个重要的选择：怀疑人生还是相信自己，每一种都会给我们的人生带来重大的影响，甚至影响我们祖国的未来。我相信我们的同学们，虽然我们依然缺乏经验，甚至有些志气，但是我相信我们有勇气和自信来面对生活的挑战并承担我们的责任。我们正努力准备接受新的任务，用我们所学习的知识将世界变得更美好。我对我们的未来充满信心。

change the ingredients of your life
so my dear friend, if faith, hope, love, endurance are added to your life, you will find the confidence to conquer your limitation and embrace new challenges. and hopefully with my speech included, you will have a fantastic speech contest.改变生活的味道
这是一杯白开水，平淡无味，对吧？可是加上点糖呢，他尝起来会有甜味；如果加的是苏打水，味道就会变苦。人生同样如此——个中滋味在于我们的选择。
善待他人，你会拥有朋友；但如果充满恶意，则会多个敌人。将爱赋予一堆红砖，你会拥有一个家；用仇恨来浇铸这堆红砖，就会铸成一座集中营。
因此亲爱的朋友们，不要抱怨人生乏味，世间无望。不喜欢生活的味道，那就换一换生活的调料吧！
三年前，我重达100多公斤，这给我带来了很多尴尬和挫折：体育课老是不及格，总被女孩们嘲笑，更不敢当众发表意见。幸而由于祖母的鼓励，我不在消极人生，而是充满自信。她曾经说过：“孩子，如果体形无法改变，为什么不把它看做自己独特的风格呢？” 我开始这样来审视人生，通过改变生活的视角，我信心大增地去改变我的人生，很快就发现一个崭新的世界。
朋友们，将信念，希望，爱意和忍性溶入生命，你就会找到自信，克服缺点，迎接人生新的挑战。最后我的演讲包括在内，希望你会看到一场精彩的演讲比赛。

when two cultures meet, there may be things in one culture, which do not fit into the tradition of the other. when this happens, we need to learn to understand and respect the customs of another culture. then there are certain things some people may not
like. to this, i will say, if you do not like it, please try to tolerate it. to learn to tolerate what you personally don’t like is a great virtue at a time when different cultures mix and merge. before us, there are two rivers, eastern and western cultures. at present, they may run in different courses. but eventually, they will converge into the vast sea of human culture.
right now, i can see peoples of eastern and western cultures, standing side by side,
singing the olympic theme song: we are hand in hand, heart to heart, together we will shape a beautiful tomorrow! thank you!
让我们共同感受东西方的融合
吉卜林说过:东方是东方，西方是西方，二者永不相聚。但是一个世纪后的今天，东西方相汇了! 它们相聚在经济领域，它们相聚在教育领域，它们相聚在艺术的殿堂。有人争论说:这种融合需要我们在东方和西方之间做出选择，但我却坚信最美好的未来在于东方和西方创造性的融合。我们可以将西方的思想，观念和技术变为我们自己所用的东西。我喜爱京剧和河南豫剧，因为它们经常使我想起自己是谁。但我也热衷于流行音乐，特别是英文歌曲。于是我将东方的旋律和西方的语言结合到了一起，它叫做西方版的河南豫剧。
当两种文化相结合的时候，也许一方的文化中的某些东西不适应另一方的传统文化。当此种情况出现时，我们需要试着理解并接受另一种文化中的风俗习惯。然而，也许有些东西你并不喜欢，对于此，我可以说，如果你不喜欢它，请试着去容忍它。当两种文化融合的时候，试着去容忍你个人不喜欢的东西是一种美德。
在我们面前有两条河流，东方文化和西方文化。现在，它们也许正朝着不同的方向流去。但是最终它们将汇合到人类文化的海洋里。
就在此时此刻，我看见东方和西方的人肩并肩的站在一起，高唱奥林匹克主题曲:我们手拉手，心靠着心，共同创造美好的明天!

farewell, indifference
who was the most well-known figure in china last month? it’s ma jiajue—the college student who murdered 4 of his roommates. many people attributed his crime to his poverty and deficient education. in my opinion, his crime also has much to do with his classmates’ indifference.
indifference is a terrible disease in today’s colleges and the whole society. it’s not rare that two students who have studied together for 4 years have never spoken to each other. it’s not rare that a student who has been absent from clafor several days is not noticed at all. it’s also not rare that a student who has severe psychological problems is not cared about at all.
some people may say ‘what the students with psychological problems like ma jiajue need is not care but psychotherapy.” however, when people are ill, what they need most is not only medical treatment, but also care from people around them. every smile and every caring word will bring sunshine to their life.篇三：2016大学五分钟英语演讲稿
