Soy food good for womenWomen 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。
If you're middle-aged and your memory's not what it used to be, check the bathroom 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 it's also possible that substances produced by fat cells, such as the hormone leptin, have direct effects on the brain. The study compared mental abilities to body mass index (BMI), a 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 less faced 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 Warwick's 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 less than 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 mass index, 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。

As food is to the body, so is learning to the mind. Our bodies grow and muscles develop with the intake of adequate nutritious food. Likewise, we should keep learning day by day to maintain our keen mental power and expand our intellectual capacity. Constant learning supplies us with inexhaustible fuel for driving us to sharpen our power of reasoning, analysis, and judgment. Learning incessantly is the surest way to keep pace with the times in the information age, and an infallible warrant of success in times of uncertainty. Once learning stops, vegetation sets in. It is a common fallacy to regard school as the only workshop for the acquisition of knowledge. On the contrary, learning should be a never-ending process, from the cradle to the grave. With the world ever changing so fast, the cease from learning for just a few days will make a person lag behind. What's worse, the animalistic instinct dormant deep in our subconsciousness will come to life, weakening our will to pursue our noble ideal, sapping our determination to sweep away obstacles to our success and strangling our desire for the refinement of our character. Lack of learning will inevitably lead to the stagnation of the mind, or even worse, its fossilization, Therefore, to stay mentally young, we have to take learning as a lifelong career. 学习之于心灵，就像食物之于身体一样。
摄取了适量的营养食物，我们的身体得以生长而肌肉得以发达。
同样地，我们应该日复一日不断地学习以保持我们敏锐的心智能力，并扩充我们的智力容量。
不断的学习提供我们用不尽的燃料，来驱使我们磨利我们的推理、分析和判断的能力。
持续的学习是在信息时代中跟时代并驾齐驱的最稳当的方法，也是在变动的世代中成功的可靠保证。
一旦学习停止，单调贫乏的生活就开始了。
视学校为汲取知识的唯一场所是种常见的谬误。
相反地，学习应该是一种无终止的历程，从生到死。
由于世界一直快速地在变动，只要学习停顿数日就将使人落后。
更糟的是，蛰伏在我们潜意识深处的兽性本能就会复活，削弱我们追求高贵理想的意志，弱化我们扫除成功障碍的决心，而且扼杀我们净化我们人格的欲望。
缺少学习将不可避免地导致心灵的停滞，甚至更糟地，使其僵化。
因此，为了保持心理年轻，我们必须将学习当作一生的事业。
2．heavy schoolwork【课业繁重】 In my opinion, the schoolwork now being assigned to high school students is too heavy. While it is true that students need to study, they need other things as well if they are to grow into healthy and well-rounded adults. High should be allowed more time for play. Playing is not wasting time, as some think. It gives them physical exercise, and also exercise their imagination. Which tends to be stifled by too much study. Finally, the pressure put on high school students by excessive schoolwork can cause serious stress, which is unhealthy physically and mentally. I do not advocate the elimination of schoolwork. I do think, however, that a reduction of the current heavy load would be beneficial to students and to the society as a whole. 我认为目前高中生的课业实在太重了，虽然说学生的确应当念书，但是要想长大成为健全的人，他门还需要一些其它的东西，所以应该给高中生较多从事娱乐的时间。
娱乐并不如某些人所想的，是在浪费时间，它可以让学生锻炼身体，发挥被繁重课业扼杀的想象力。
此外，繁重的课业加诸在高中生身上的压力可能引起严重的情绪紧张，这对身心都有害。
我并非主张废除学校课业，但是我认为减轻目前繁重的课业对于学生和整个社会都是有益的。
3．Time【时间】 Lost time is never found again. This is something which I learned very clearly last semester. I spent so much time fooling around that my grades began to suffer. I finally realized that something had to be done. It was time for a change. Now I have a new plan for using my time wisely. I have set my alarm clock ahead half an hour. This will give me a head start on the day. I have also decided to keep a log of what I do and when I do it. Looking back on what I’ve done will give me some ideas on how to reorganize my time. 时光一去不复返，这是我上学期清楚学到的教训。
我浪费很多时间四处游荡，以致于我的成绩开始退步。
最后我终于了解到我必须有所作为；该是痛改前非的时候了。
现在我有一个明智运用时间的新方法。
我已将闹钟早拨半小时，这将使我这一天的作息提前开始。
我也决定将我所做的一切及做这些事的时间记录下来。
回顾我所做的事情会启发我如何重新安排我的时间。
4．Work and Play【工作与娱乐】 Work and play do not contradict each other; in fact, they complement each other. As the saying goes, All work and no play makes Jack a dull boy. A life burdened with work leads you nowhere, for you would get tired and bored with your daily routine work. On the other hand, proper recreation will relieve the tension and discomfort of our monotonous life because it offers you various ways to let out your pent-up emotions. What I usually do to relax after school is jogging and seeing movies. Usually I don't spare time for exercise, but I value the physical education class at school. Jogging several rounds in the field certainly relieves the day's pressure. On weekends, I'll catch the morning movie for my visual enjoyment. I feel revived and energetic for another week's work-load. 工作与娱乐并不互相冲突，事实上，它们之间的关系还相辅相成。
有句格言说：「整日工作而没有休闲娱乐，会令人变得沉闷乏味。
」被工作重担压得喘不过气来的生活，将使你一事无成，因为你将对一成不变的例行公事感到厌烦。
由另一方面来说，适度的娱乐活动能提供各种管道，来渲泄你被压抑的情绪，减轻单调生活中的紧张与不悦。
放学之后，我最常做的休闲活动，便是慢跑与看电影。
通常我并不特地拨出时间来做运动，但是我很重视学校的体育课。
在操场上慢跑几圈，无疑地可以减轻一天的压力。
在周末时，我都去看早场电影，享受视觉飨宴。
如此一来，我将有如再生般的充沛活力，去面对下一星期的工作量。
5．My first Job【我的第一份工作】 My first job was at a cramming school. It was three years ago when I just graduated from junior high school and finished the entrance examination. since I had nothing to do that summer, I decided to find a job, tasting the joy of independence. I was responsible for answering the telephone and taking the message. I worked eight hours a day, six days a week. The work was not difficult nor heavy to me and I guess I did well. The most delighted thing was perhaps that I could spend the money I earned all by myself. 我的第一份工作是在一家补习班做事。
那是三年前我刚从国中毕业，考完联考时的事了。
既然我那整个夏天都闲着没事，倒不如找份差事，尝尝独立赚钱的快乐。
我负责接听电话且纪录留言的工作。
我一天工作八小时，一星期工作六天。
那份工作对我而言既不困难亦不沉重，所以我想我还满称职的。
而最令人快乐的事大概莫过于花全部由自己赚来的钱了
6．My Favorite Sports【我最喜爱的运动】 Sports help everyone to keep healthy, happy, and efficient. So I pay special attention to games, especially table-tennis. Table tennis is my favorite game. I play it almost every day. Table-tennis is an ideal game us because it brings the whole body into action. It strengthens our muscles, expands our lungs, promotes the circulation of the blood, and causes a healthy action of the skin. Besides, it is very amusing and does not cost us much money. Table-tennis is very moderate; it is not so rough as football. It is an indoor game and can be played even on rainy days. Thus, it is my favorite kind of exercise. 运动能帮助每一个人保持健康、快乐和有效率。
所以我特别重视运动，特别是桌球，桌球是我最喜欢的运动。
我几乎每天玩。
桌球对我们而言，是一项理想的运动，因为它可以使我们全身运动，它可以增强我们的肌肉，扩张我们的肺部，促进血液循环，并且使肌肤产生健康作用，此外，它很有趣而且所费不多。
桌球是相当温和适中的，它不像足球那么粗野。
它是一种室内运动，甚至在下雨天也能玩。
因此，桌球是我最喜爱的一种运动。
One day, a father and his little son were going home. At this age, the boy was interested in all kinds of things and was always asking questions. Now, he asked, What's the meaning of the word 'Drunk', dad? Well, my son, his father replied, look, there are standing two policemen. If I regard the two policemen as four then I am drunk. But, dad, the boy said, there's only ONE policeman! 醉酒 一天，父亲与小儿子一道回家。
这个孩子正处于那种对什么事都很感兴趣的年龄，老是有提不完的问题。
他向父亲发问道：“爸爸，‘醉’字是什么意思
” “唔，孩子，”父亲回答说，“你瞧那儿站着两个警察。
如果我把他们看成了四个，那么我就算醉了。
” “可是，爸爸， ”孩子说，“那儿只有一个警察呀
”
关于好习惯的英语演讲稿
HabitLike everyone else, I have good and bad habits. Most of my habits don’t have a very serious effect on my daily life. Unfortunately, one of them does. I am a procrastinator. I always put off doing things until the last possible moment. I picked up this bad habit from my brother. This habit really causes me problem, especially when I have many assignments due^ about the same time. My life seems to run in cycles of leisurely heaven and incredibly frantic hell. I wish I could get rid of this terrible habit.这种难度可以吗，需要的话可以帮你续写，短消息我
党在我心中英语演讲稿 不要太难的 时间不要太长了about5,6分钟
名人励志英语演讲稿Most people would like to be popular with others, but not everyone can achieve this goal. What is the secret to popularity? In fact, it is very si-mp-le. The first step is to improve our appearance. We should always make sure that we stay in good shape and drewell. When we are healthy and well-groomed, we will not only look better but also feel better. In addition, we should smile and appear friendly. After all, our facial expression is an important part of our appearance. If we can do this, people will be attracted to our good looks and impressed by our confidence.Another important step is developing more consideration for others. We should always put others first and place their interests before our own. It's also important to be good listeners; in this way people will feel comfortable enough to confide in us. However, no matter what we do, we must not gossip. Above all, we must remember to be ourselves, not phonies. Only by being sincere and respectful of others can we earn their respect. If we can do all of the above, I am sure popularity will come our way.如何才能受人欢迎大部分的人都想受人欢迎，但是并非每个人都能达到目标。
受欢迎的秘诀何在?事实上是很简单的。
步骤一，先改善我们的外表。
我们得确保自己很健康，并且穿着体面。
当我们既健康又穿戴整齐时，不仅看起来更有精神，自己也会觉得好多了。
此外，我们要保持微笑并表现得很友善。
毕竟，脸部表情是外观很重要的一环。
如果我们能做到这一点，别人会被我们的美好外表所吸引，并对我们的自信印象深刻。
另一个重要步骤，就是培养对别人的体贴。
永远以他人为重，并把别人的利益放在自己的利益之前。
当个好听众也是很重要的;如此一来，别人才能很自在地对我们吐露心事。
然而，不管我们做什么事，绝对不要说闲言闲语。
最重要的是，要做自己，不要当虚伪的人。
只有对人真诚又尊重时，才能赢得他人的尊敬。
如果我们能做到以上几点，我相信受人欢迎是指日可待的事。
Strive for balance in life 努力保持生活的平衡by Brain Dyson 布莱恩•戴森(可口可乐公司总裁)Imagine life as a game in which you are juggling some five balls in the air. You name them----work, family, health, friends and spirit and you’re keeping all of these in the air. You will soon understand that work is a rubber ball. If you drop one it, it will bounce back. But the other four balls—family, health, friends, and spirit—are made of glass. If you drop one of those, they will be irrevocably scuffed, marked, nicked, damaged or even shattered. They will never be the same.You must understand that and strive for balance in your life. How?Don’t undermine your worth by comparing yourself with others. It is because we are different that each of us is special.Don’t set your goals by what other people deem important. Only you know what is best for you.Don’t take for granted the things closest to your heart. Cling to them as they were your life, for without them, life is meaningless.Don’t let your life slip through your fingers by living in the past or for the future. By living your life one day at a time you live ALL the days of your life.Don’t give up when you still have something to give. Nothing is really over until the moment you stop trying.Don’t be afraid to admit that you are lethan perfect. It is this fragile thread that binds us to each together.Don’t be afraid to encourage risks. It is by taking chances that we learn how to be brave.Don’t shut love out of your life by saying it’s impossible to find. The quickest way to receive love is to give; the fastest way to lose love is to hold it too tightly, and the best way to keep love is to give it wings.Don’t run through life so fast that you forget not only where you’ve been, but also where you are going.Don’t forget, a person’s greatest emotional need is to feel appreciated.Don’t be afraid to learn. Knowledge is weightless, a treasure you can always carry easily.Don’t use time or words carelessly. Neither can be retrieved.Life is not a race, but a journey to be savored each step of the way. Yesterday is history, tomorrow is a mystery, and today is gift…… that’s why we call it the present.想象生命是一种往空中抛五个球的游戏，你把这五个球分别取名为：工作、家庭、朋友和心灵，而且你要努力不让它们落地。
你很快会了解到工作是一个橡皮球，如果你让它落地了，它还是会反弹起来。
但是，家庭、健康、朋友和心灵这四个球是用玻璃做成的。
如果你让它们掉到地上，它们将会不可避免地遭到磨损，留下印记、划痕，摔破甚至碎落一地。
它们将永远不会跟以前一样。
你必须了解这个道理，并且努力保持生活的平衡。
但要怎么才做得到呢?不要拿自己和他人比较而贬低自己的价值。
正是因为我们彼此不同，所以每个人才很特别。
不要因为别人看重哪些东西而把它们设定为自己的目标。
只有你才知道什么最适合自己。
不要将最亲密的人视为理所当然。
好好珍惜他们，就像是你的生命一样，因为没有他们，生命将失去意义。
不要让你的生命总在留恋过去或是遥想未来中流逝。
如果你活在每个当下，你就活出了人生的精彩。
当你还能给予的时候别轻言放弃。
只要你不放弃，万事皆有可能。
不要害怕承认你并非完美。
我们正是藉由这脆弱的细丝紧密地联系在一起。
不要害怕遇到危险。
我们正是在冒险中学会勇敢的。
不要以真爱难求为借口而紧闭心扉。
找到爱最快的方法就是给予你的爱;失去爱最快的方法就是紧紧地守着你的爱不放;维系爱最好的方法就是给爱一双翅膀。
不要匆忙地走完你的一生，以至于忘了自己到过哪里，要往哪里去。
不要害怕学习。
知识不会成为负担，是你可以轻松携带的珍宝。
不要漫不经心地蹉跎光阴或信口开河。
时间与话语都是收不回来的。
生活不是一场赛跑，而是每一步都需要体味的旅程。
昨天已成历史，明天还未可知，而今天则是一份礼物：那就是我们为什么称它为“当下”(译注：此处是双关语present的另一个意思是“礼物”)的原因。
