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, reced 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 proced 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 ration 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。”

❸ 关注四级英语的实训报告总结

抓语篇学习、重阅读能力
从近几年的高考试题来看，死记硬背，强化训练，沉湎专于“题海战术”属是难以出好成绩的。将中心和重心放在单项选择上是不合时宜的。因此，要根据自己的实际情况，制定出切实可行的复习计划。做到按部就班，有条不紊，循序渐进。其中，语篇学习最应引起学生的足够重视。

高三课本中文章题材广、内容新颖，知识覆盖面宽。因此，学生应充分利用高三课本中的阅读材料，从文章的内容、文章的结构、作者的观点、态度及相关的背景知识巧妙设置问题，不断提高自己的阅读能力，开拓知识视野。同时，文章的新颖内容还可以提高学生对英语的学习兴趣。

Dear Xiao He,
Thank you ever so much for having invited me for the tour of Yunnan, your home province. I had a fantastic time with you and your family. Your great hospitality will be unforgettable throughout my life.
When I think of those gorgeous places of scenic beauty you showed me around, I couldn’t be more delighted. And the pineapple pie Grandma prepared for me is out of this world. I had never had so delicious food! Indeed, I am still missing your snug log-cabin, small and cozy, which was turned into my dream house in fairy land those nights.
Would you come to Harbin, my home town, some time this summer vacation? Harbin, a beautiful place frequently referred to as Oriental Paris, offers a picture of another kind. I can assure you another pleasant tour. My family and I cannot wait to see you here.
Yours,
Li Ming

September, 11
Dear President,
I am a sophomore with the Department of Law. My name is Wang Ming. I am writing to you today to intimate you with something undesirable that I have found in the University Library.
You may or may not realize how much our library, the landmark of our university or even of our town, weighs in our minds. It is a place we are most proud of and where we like to spend most of our time. In such an honorable place we have noticed recently some phenomena which hurt our eye. Some seats in the reading rooms are ‘permanently reserved vacant seats’, that is, some students “occupy” some seats they never come to use. What a terrible waste of valuable resource! Some other students are too noisy, talking among themselves, leaving mobile phone beeping anytime. And some library staff is ill-mannered and rude and not helpful most of time. These and other undesirable things have already done damage to the fame of our university and caused a lot of inconvenience to the users.
Dear President, we hope that something can be done to change and reverse the current situation. Let our cozy, comfortable, quiet, effective library come back.
Best wishes
Yours sincerely,

2．记叙文 例：A Welcome Back Celebration
1.杨玲生病，情绪低落.
2.班上同学准备cheer her up.
3.举办一场欢迎party.
Yang Ling is my fellow classmate and friend. Recently she had a terrible condition and has been hospitalized for over a month. She was depressed, sad and downhearted. She told us so many things are working against her, and she didn’t know how to change and redirect herself.
The day before she was released from hospital, we, some of her friends decided to give a surprise to cheer her up the next day. That night, she came back, shoulders bent and head fallen. She was so deep in her bad mood that she didn’t realize that her dorm is the only one in the building that is dark. She turned the key in the lock and opened the door when the room was suddenly lit like a bright day. Her eyes sparkled with delight and surprise. She saw all her classmates crowded in this tiny room. Everyone was holding something in his hand, flowers, fruits, cards, cheering, “Welcome back!” She was so moved that she burst into tears. And smile returned to her pretty face. She said “Thank you all.” heartedly.
Ever since that day, happiness and delight have stayed with her. Life is so wonderful.

3．论说文
例：Buying or Borrowing Books?
（1） 有些人认为书应该借来看

（3） 你的选择？
Buying or Borrowing Books?

Books can arm us with knowledge and information we need to make success of life. There are generally two ways in which we can have access to books: borrowing or buying. While millions are borrowing books, I still think buying them best suits me and gives me the greatest pleasure.

Many people choose to borrow books. For one thing, borrowing books can save us huge amounts of money. For another, if we borrow books from the library or friends, we normally have deadline to finish them. And consequently we can read more books in a limited time, just as a famous Chinese saying goes, “books can not be read unless borrowed.”

I believe that advantages for buying books are more obvious and compelling. Firstly, we can keep the books as long as we wish. Secondly, we can take whatever notes on the margin of the pages of the books. Finally, the process of selecting and keeping books can be a great fun.

4．口语作文
例：工作总结演讲
1. 简述上周五系学生会搞的一次以环保为主题的到某一湖区拾trash的活动。
2. 上述活动的效果及存在的问题。
3. 你的建议。
My fellow students,
Last Friday, the Students’ Union of our Department organized a clean-up project to Zhongshan Lake. The purpose of this project is to enhance(加强)the environment awareness of general public. Late in the afternoon around 4, a group of 35 volunteers went to the park where we pick up the trash(垃圾)left by some tourists. As head of the group, I would like to report to you on the event.
Actually, we did a wonderful job. When we were collecting the trash near the lake, many people paused to watch and then came to our help, showing considerable appreciation and support. But our work still left some to be desired. For one thing, since our project started late in the afternoon, hours were not long enough to attract enough people as we had predicted. For the other, lots of people passed by apparently not knowing what we were doing. But for these two drawbacks, our project could have been much better and more effective.
So, following are two of my suggestions: next time we have similar activities, try to start earlier, say in the morning. In this case we can put in more hours. And also, as we are getting along, we can put up some posters to tell people what we are doing and call their attention to environment protection. Thank you.

5．图表作文

A： staying at home
B: traveling
C: doing social investigation
D: other ways

From the two charts, we can see that in the past ten years the students who go traveling and do social investigations ring vacations have increased greatly while those who stay at home have decreased a lot.
There are several reasons for the changes. Firstly, with the development of economy, many people have become better off. Students can get financial support from their parents for traveling. Secondly, tourism has greatly developed over the past ten years. Many new scenic spots have been built and exploited. In addition, the students today are expected and encouraged to participate in facing the real world. In this way they can obtain the necessary experiences required when they go job-hunting upon graation.
From the changes in the charts, we can predict that more and more college students will make their vacations interesting and worthwhile by going to the outside world instead of staying at home.

Directions: For this part, you are allowed 30 minutes to write a short essay on the topic of Studying Abroad. You should write at least

120 words following the outline given bellow:

1. 近几年来越来越多的学生选择留学

2. 出现这种现象的原因

3. 这种现象可能带来的影响

四级模考参考范文：

Recent years have witnessed a phenomenon that more and more students swarm into foreign countries to finish their ecation.They have not considered our homeland as the unique place to enrich their knowledge any more. Instead, some excellent boys and girls whose financial condition is fine simultaneously began to pay their attention on some oversea prestigious colleges and institutions and dream to get degrees there.

There are several reasons to cause this change. First of all, with the globalization and much more frequent communications with developed countries, most of the people in China get to realize the wide gaps in many fields, especially in science and technology,between China and western countries. They thirst for studying aboard to get ready better for the fierce competition in the job-hunting market. Moreover, the life in foreign countries is usually attractive to young people and studying aboard may satisfy their curiosity.

Besides, the rapid development of our mother country and the remarkable growth in our income make going abroad to study available, which is almost impossible to average Chinese students in the past.

The move-out of our students changes our society a lot.

On one hand, being students in foreign universities will widen their view and offer them more possibility to get favorite jobs. And consequently their success will draw more latecomers to do the same thing.On the other hand, if the majority of them will not go back to China to work in the future, our fatherland will probably suffer a significant loss which may be difficult to be estimated by money.
