    We can slow down aging. That is the message Dr. Shen Ziyin wants to give the world. And the Chinese doctor claims that he has found an answer to the problems of aging. His solution is a herbal medicine（草药）to slow the process of aging.

        Dr. Shen Ziyin has been trained in Western medicine. At the same time he studied traditional Chinese medicine. And, he has been working for the past forty years to put together the best of both and find a cure for aging. He has taken a hint from the ancient Chinese medicine system called “Shen”.

        According to Shen, it is the kidney（肾脏）which adjusts the functioning of the body as well as its aging process. It is responsible for the level of activity that the human bodies go through. Studies conducted by Dr. Shen show that herbal medicine based on the Shen system slows the aging process, says a report in the Telegraph newspaper. We notice that when people grow old, they have reduced strength, loss of hair, backache, weakness, wrinkles and so on. This happens because when people grow old, their bodies produce T-cells. These T-cells contain a particular substance called Fas. Fas makes the cells in the body destruct themselves.

        So the only way to slow down aging is to slow the production of T-cells in the body. This can happen if people eat low calorie food. Then the body is not active enough to produce extra T-cells. But, is going hungry all the time a good price to pay for staying young? This is where Dr. Shen’s herbal medicine comes in. But how effective it will be, only time can tell.

    1.How did Dr. Shen find the solution to the problem of aging?

        A. By studying Western medicine.

        B. By learning traditional Chinese medicine.

        C. By combining both Western and Chinese medicine.

        D. By doing research on both Western and Chinese people.

    2.What plays the most important role in keeping people young according to Shen?

        A. Medical treatment.

        B. Positive life attitude.

        C. People’s good kidney.

        D. Level of people’s activity.

    3.The reason why people become old is that     .

        A. their bodies produce T-cells

        B. they become weaker and weaker

        C. they have reduced strength, loss of hair

        D. their bodies are unable to fight diseases

    4.We can probably learn from the passage that     .

        A. producing more low calorie food allows people to keep young

        B. it remains unknown how effective Dr. Shen’s herbal medicine is

        C. people should try to quicken the production of T-cells in the body

    D. the more Chinese herbal medicine people drink, the better for health

    What would life be like without rich, creamy, mouthwatering, melt-in-your-mouth chocolate?

    Life would be bitter for most Americans. They spend about $13 billion a year buying all sorts of chocolate treats.

    However, for the African children who toil under slavelike conditions on cacao plantations, life is not sweet. The cacao bean is the main ingredient in the chocolate. According to a 2002 survey by the International Institute of Tropical Agriculture and the US Agency for International Development, about 284,000 children work in dangerous conditions on cacao farms in western Africa.

    More than half those children are younger than 14. Many were sold into forced labor to work 12 hours or more a day on the cacao plantations.

    A number of international organizations, including several African governments, recently began a program to eliminate(消除) child labor on cacao plantations. Under the program, government officials will remove children from abusive working situations while teaching farmers about child labor issues.

    The program will also make borrowing money easier for cacao farmers. Officials hope farmers will use the money to invest in their farms and hire paid laborers.

    1.The cacao bean is the main ingredient in _______.

    A．treats

    B．coffee

    C．chocolate

    D．cigarettes

    A．About 284,000.

    B．About 142,000.

    C．About 467,000.

    D．About 876,000.

    3.From the passage, you can reasonably conclude that _______.

    A．cacao farms in western Africa rely heavily on child labor

    B．children in Africa know how to make the best chocolate

    The library is one of the most popular places at a western university. Students turn to it for research, conversations about class, and many other services.

    Compared with Chinese libraries, college libraries, college libraries in the US and UK tent to offer more resources. A postgraduate at Yale University can borrow as many as 225 books at a time.

    In addition to borrowing books, there are online and electronic resources. These include a database search of popular and academic material, such as LexisNexis Academic, which offer items from newspapers and magazines.

    Although books and articles are the items that students ask for most frequently, some libraries provide audio and video recordings, maps and sheet music （活页乐谱）. At some schools, teachers and tutors put electronic copies of their teaching PPTs on the library Web to give easier access for students.

    Another useful service in Western college libraries is the Interlibrary Loan. This allows a student at one school to borrow books from another school. The loan request is make through the student’s college library, which gets the book, gives it to the user, and arranges for its return.

    Technology has brought more services to students and has made libraries attractive. Some universities have services for students to send messages through the computer or mobile texts to ask the library staff for information.

    Earlier this year, Harvard University introduced a new Scan and Deliver service, allowing students to make requests for parts of books and articles. Requests made through the system are handled by library staff. The student receives and e-mail with an Internet link to the scanned pages. The service is free and all material comes within four days.

    It used to be that libraries didn’t allow food or drinks. But that rule is changing and many of them now contain a café so students can spend as much time as they want in the library.

    Actually, some US university libraries are now all-night affairs, or have at least one study room open all night.

    1. In Western college libraries a postgraduate can ______.

    A. have a free drink or a meal

    B. borrow as many books as they want

    C. access not only books but other study resources

    D. ask questions and get answers from their tutors

    2. LexisNexis Academic is the name of ______.

    A. a database

    B. a library

    C. a university

    D. a guide

    3. How can a college student borrow books from other college’s libraries?

    A. By going to these libraries.

    B. By getting them through the Internet.

    C. By sending messages through the computer or mobile texts.

    D. By borrowing them through their own library.

    4. Which of the following statements is TRUE?

    A. Chinese library services are better than western ones.

    B. Library staff play an important role in college library service.

    C. Postgraduates can post their own PPTs to the library website.

    D. 24-hour services are adopted in all western libraries nowadays.

    Butter is bad for you—so is margarine（人造黄油）．Coffee raises blood pressure, but may protect against cancer．Alcohol is okay, but only if it's wine．The confusing studies on what is safe to eat and drink are enough to make it impossible for anyone to understand what "good food" is．

    Take the margarine-butter debate for example．Studies that linked fat—found mostly in animal products such as meat and butter—with cancer and heart disease sent millions rushing to buy margarine．But then another study found that people who ate a lot of margarine also had high levels of heart disease．For those who have a firm faith in science, this seems to be the end of the world．

    But many doctors point out that their advice has never been conflicting．For years, and in various countries, they have recommended eating less fat．

    People in western countries such as Britain and the United States get about 40 percent of their calories from fat．Doctors say this should be around 30 or even 25 percent,

    "We must try to reduce total fat," said Dr．Robert Richardson of the University of Edinburgh, who has been studying the effects of fat on human health for years．

    "We need to go to more such food as bread, in particular brown bread, and more fruit and vegetables．"

    Fresh produce may not be so safe, either．Last month the British Government advised consumers to peel their pears before eating, while many Americans briefly avoided apples because of fears over an insect killing chemical．

    But Dr．Arnold, a British scientist, said any risk of such poisoning would be outweighed by the costs of not eating plant foods．

    "On balance, if you were to put both risks against each other, the advice has to be eating as much fruit and vegetable daily as possible," she said．

    In general, doctors conclude, variety truly is the best policy．"The general advice is pretty much the same advice that doctors have been talking about for a long time—a varied diet, a mixture of foods and not too much of any one," Arnold said．

    1.In which section of the magazine are you most likely to find this passage?

        A．Arts and Culture                     B．Entertainment    

        C．Nature                               D．Health

    2.The British Government advised consumers to peel their pears before eating because ________．

        A．it found that there were insects on the pears

        B．it wanted consumers to avoid insect, killing chemicals

        C．the skin of pears was found to be bad for people's health

        D．it was a bad habit not to peel them

    3.The underlined word "outweigh" （Para. 8） means " __________．"

        A．to be heavier than usual or allowed                      B．to be more dangerous than

        C．to be greater in value or importance than                D．to be considered less important than

    4.What can we infer from the passage?

        A．Many doctors say that their advice has never been conflicting．

        B．Science provides answers to all our questions．

        C．We should peel our pears before eating．

        D．We should eat plant foods despite the risk of poisoning．
