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.

據美國研究人員報告，兒童時期經常吃豆類食品的女性患乳腺癌的風險較小。另一組研究人員則向美國癌症研究協會提出，一周吃幾次魚的男性患結腸癌的幾率較小。

這兩項研究進一步證明了飲食對於防癌的作用。癌症防治專家認為，在所有種類的癌症中，多達三分之二都是由吸煙、節食及缺乏鍛煉等不健康的生活方式造成的。

美國全國癌症研究所和夏威夷大學的研究人員發現，在5歲至11歲時經常吃豆腐、味噌等豆類食品的女性患乳腺癌的幾率要低58%。至於豆類食品為什麼可以防癌還不清楚，不過大豆中所含的名叫異黃酮的化合物具有雌性激素的作用。

另一項研究表明，一周吃魚至少五次的男性患結腸癌的風險要比那些一周都吃不到一次魚的男性低40%。

很多魚類中所富含的Omega-3脂肪酸能夠抑制環氧化酶2的活性。環氧化酶2會引起發炎，這可能會刺激腫瘤的生長。
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.

研究人員提醒，如果你已步入中年，發現自己的記憶力不如從前，那麼你得小心體重了。研究表明，超重的人記憶測試的得分要比較瘦的人低。

研究發現，體重偏大的中年人今後患老年痴呆症的可能性較大。

研究報告在《神經學》期刊上發表，研究人員推斷，心血管疾病及糖尿病的高發現象可以解釋其中的原因。此外，脂肪細胞所產生的物質，如瘦體激素，對大腦有直接影響。

此項研究將調查對象的智力與體重指數進行了對比。體重指數指的是身高和體重之間的比例，主要用來衡量一個人是否偏胖或肥胖。體重指數為25或25以上的人偏胖，達到30或30以上的人則為肥胖。

研究人員還對體重指數和認知功能間的關系進行了研究，他們在法國對2223位年齡在32歲至62歲間的健康男女進行了認知測試。

研究發現，體重指數越大，認知測試的得分越低。其中一項"單詞記憶"的測試結果表明，在16個單詞中，體重指數為20的人平均能記住9個，而體重指數為30的人平均只能記住7個。

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) 本周一公布的一項大規模英國調查表明，睡眠不足的人死於心臟病的幾率是睡眠充足者的兩倍多。

目前其中的原因尚不清楚，但研究人員稱，睡眠不足會導致血壓升高，從而增大患心臟病和中風的風險。

一項針對1萬名政府職員、長達17年的跟蹤調查表明，每晚睡眠時間從七個小時減少到五個小時或更少的人因各種原因而死亡的幾率是睡眠正常者的1.7倍，而且死於心血管疾病的風險也增加了1倍多。

沃里克大學醫學院的心血管葯物學教授弗朗西斯哥•卡普西奧在英國睡眠學會在劍橋召開的一年一度的研討會上說，這一研究成果揭示了忙碌的現代生活中潛在的危險。

他在接受記者采訪時說：「三分之一的英國人以及超過40%的美國人每晚的睡眠時間常常達不到五個小時，所以這個問題不可小視。」

此前有調查發現輪班及睡眠中斷會對健康產生潛在威脅。但卡普西奧及其同事的這項調查則首次揭示了睡眠時間長短與死亡率之間的關系。該調查由英國政府和美國基金提供資助。

該調查對年齡在35歲至55歲之間的人在1985年至1988年以及1992年至1993年兩個階段的睡眠模式進行了探究，並對這一人群截至2004年的死亡率進行了追蹤。

調查還考慮到了調查對象的初始年齡、性別、是否吸煙喝酒、體重指數、血壓及膽固醇指標等其它可能的風險因素。

卡普西奧說，睡眠時間過長也可能導致如抑鬱症及癌因性疲乏等其它健康問題。

他說：「就預防而言，我們的研究結果表明，每晚睡眠時間持續保持在七小時左右最益於身體健康。」

❸ 關注四級英語的實訓報告總結

抓語篇學習、重閱讀能力
從近幾年的高考試題來看，死記硬背，強化訓練，沉湎專於「題海戰術」屬是難以出好成績的。將中心和重心放在單項選擇上是不合時宜的。因此，要根據自己的實際情況，制定出切實可行的復習計劃。做到按部就班，有條不紊，循序漸進。其中，語篇學習最應引起學生的足夠重視。

高三課本中文章題材廣、內容新穎，知識覆蓋面寬。因此，學生應充分利用高三課本中的閱讀材料，從文章的內容、文章的結構、作者的觀點、態度及相關的背景知識巧妙設置問題，不斷提高自己的閱讀能力，開拓知識視野。同時，文章的新穎內容還可以提高學生對英語的學習興趣。

June 17th , 2006
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．記敘文 例：A Welcome Back Celebration
1.楊玲生病，情緒低落.
2.班上同學准備cheer her up.
3.舉辦一場歡迎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.

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．口語作文
例：工作總結演講
1. 簡述上周五系學生會搞的一次以環保為主題的到某一湖區拾trash的活動。
2. 上述活動的效果及存在的問題。
3. 你的建議。
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(加強)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．圖表作文

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. 近幾年來越來越多的學生選擇留學

2. 出現這種現象的原因

3. 這種現象可能帶來的影響

四級模考參考範文：

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.
