[单项选择]Passage Four

S. intelligence agencies are being drawn into the debate over whether the United States is imminently threatened by a deadly outbreak of bird influenza and whether the Bush administration has adequately prepared for such an epidemic. Over the last two weeks, the administration has held bird flu briefings classified "Top Secret/Sensitive Compartmented Information" for members of both houses of Congress. A counterterrorism official indicated that the intelligence community is also studying whether it would be possible for terrorists to somehow exploit the avian flu virus and use it against the United States, though there is no evidence that terrorists have in any way tried to do so. The World Health Organization is warning that if a pandemic (a disease for which ther

[单项选择]Passage Four
You have been badly injured in a car accident. It is necessary to give you a blood transfusion because you lost a great deal of blood in the accident. However, special care must be taken in selecting new blood for you. If the blood is too different from your own, the transfusion could kill you.
There are four basic types of blood; A, B, AB and O. A simple test can indicate a person’s blood type. Everybody is born with one of these four types of blood. Blood type, like hair color and height, is inherited from parents.
Because of substances contained in each type, the four groups must be transfused carefully. Basically, A and B cannot be mixed. A and B cannot receive AB, but AB may receive A or B. O can give to any other group, hence it is often called the universal donor. For the opposite reason, AB sometimes called the univ
A. Getting Blood and Plasma
B. Special Blood and Colors
C. Human Blood Types
D. The Blood Bank of a Hospital

Passage Four

There are two basic ways to see growth: one as a product, the other as a process. People have generally viewed personal growth as an external result or product that can easily be identified and measured. The worker who gets a promotion, the student whose grades improve, the foreigner who learns a new language - all these are examples of people who have measurable results to show for their efforts.
By contrast, the process of personal growth is much more difficult to determine, since by definition it is a journey and not the specific signposts or landmarks(路标) along the way. The process is not the road itself, but rather the attitudes and feelings people have, their caution or courage, as they encounter new experiences and unexpected obstacles(障碍). In this process, the journey never really ends; there are al
A. he has given up his smoking habit
B. he has made great efforts in his work
C. he is interested in making anything new
D. he has tried to determine where he is on his journey
[单项选择]Passage Four
Unless you have visited the southern United States, you probably have never heard of kudzu. Kudzu, as any southern farmer will sadly tell you, is a super-powered weed. It is a strong climbing vine. Once it gets started, kudzu is almost impossible to stop. It climbs to the tops of the tallest trees. It can cover large buildings. Whole barns and farm houses have been known to disappear from view. It has even been said to engulf small, slow-moving children, but that is probably an exaggeration. Still, wherever it grows, its thick, twisting vines are hard to remove.
Kudzu was once thought to be a helpful plant. Originally found in Asia, it was brought to America to help fight erosion. It was planted where its tough roots, which grow up to five feet long, could help hold back the soil. But the plant soon spread to places where it wasn’t wanted. Farmers now have to fight to keep it from eating up all the nutrients in the soil and killing other plants.
A. kudzu
B. farming
C. the South
D. soil erosion
[单项选择]Passage Four
Many tourists must have dreamed of owning a small house in a foreign country -- perhaps on a stretch of lonely coast -- to which they could return year after year to enjoy the sun and the sea. Others, with even bigger ideas and a lot more money to spend, think of buying hotels. In any case, it is absolutely essential to know a great deal about the value of property, otherwise the buyer may be at the mercy of(由……摆布) dishonest agents.
Some tourists, however, are so foolish that they really deserve to be cheated by agents. We would consider a person mad if he walked into a museum and asked to "buy" a great work of art. Though no one has told us, we all know that certain things can never be sold, no matter how much money is offered. Yet, nearly every year since 1944, a buyer has been found for the Colosseum (古罗马圆形剧场) in Rome. The f
A. indifferent
B. concerned
C. defensive
D. scornful
