2、English ａｎｄ　English Community1 There is no doubt that English is a useful language. The people who speak English today make up the largest speech community in the world with the exception of speakers of Chinese. 2 A speech community is similar to other kinds of communities. The people who make up the community share a common language. Often they live side by side, as they do in a neighborhood, a village, ｏｒa city. More often they form a whole country. National boundaries, however, are not always the same as the boundaries of a speech community. A speech community is anyｇｒｏｕｐof people who speak the same language no matter where they happen to live. 3 We may say that anyone who speaks English belongs to the English speech community. Fｏｒconvenience, we may divide the speakers into two groups: one in which the speakers use English as their native language, the other in which the speakers learn English as a second language fｏｒthe purpose of education, commerce, ａｎｄ　so on. 4 Learning a second language extends one\'s vision ａｎｄ　expands the mind. The history ａｎｄ　literature of a second language record the real ａｎｄ　fictional lives of people ａｎｄ　their culture; a knowledge of them adds to our ability to understａｎｄ　ａｎｄ　to feel as they feel. Learning English as asecond language provides another means of communication through which the window of the entire English speech community becomes a part of our heritage. Paragraph 2____【单选题】

A.Threat Posed by English

B.Definition ofa Speech Community

C.Benefits ofLeaming a Second Language

D.Advantages of Learning Chinese

E.Two Groups ofthe English Speech Community

F.A Widely Used Language

正确答案:B

答案解析:文章第2段主要讲的是什么是a speech community，即a speech community的定义。

3、The orangutanAmong all the animals, the ape is most like human beings. Both people ａｎｄ　apes have the similar brain structure, the similar nerve system, ａｎｄ　the similar kind of blood. There are four kinds of apes: the chimpanzee (黑猩猩), the orangutan (猩猩), the gorilla (大猩猩), ａｎｄ　the gibbon (长臂猿). They live in the deep forests ａｎｄ　warm tropical regions of Africa ａｎｄ　of Southeast Asia, including Indonesia. All apes are covered with brown, reddish-brown, ｏｒblack hair everywhere on their bodies except their faces, feet, ａｎｄ　hands. Their hands each have four fingers ａｎｄ　a thumb that helps them grip things the way our thumbs help us. But they also have a thumb on each foot instead of a big toe. Thus they can hold things with their feet also. Having short, weak legs, apes do not walk on the ground very much. However, their arms are very strong. This enables them to swing from branches ａｎｄ　travel very quickly from tree to tree. These animals live in small family groups that move from place to place in search of vegetables ａｎｄ　fruits. They also eat eggs, small animals, nuts, ａｎｄ　insects. When they are tired, they build nests in the trees. But they rarely sleep there fｏｒmore than a night ｏｒtwo. Then they move on to look fｏｒmore food. There are some differences among the following three kids of apes. The gibbon is never more than three feet high ａｎｄ　weight only about fourteen pounds. The gorilla grows to be six feet tall ａｎｄ　weight up to 600 pounds. The orangutan is smaller than the gorilla. It stands three to five feet tall ａｎｄ　weight up to 200 pounds. Chimpanzees are the smartest of all apes. They can be taught to sit at a table ａｎｄ　eat, to dress themselves, ａｎｄ　to do things that human children can do. What does the first paragraph tell us?【单选题】

A.The ape looks like human beings most.

B.People ａｎｄ　the ape think alike.

C.People ａｎｄ　the ape behave alike.

D.The ape is the most intellectual animal in the world.

正确答案:A

答案解析:由文章首句可知，在自然界中，猿与人最相似，故选A。

4、Citizen ScientistsUnderstanding how nature responds to climate change will require monitoring key life cycle event-flowering, the appearance of leaves, the first frog calls of the spring all around the world. But ecologists can\'t be everywhere so they\'re turning to non-scientists, sometimes called citizen scientists, fｏｒhelp. Climate scientists are not present everywhere. Because there are so many places in the world ａｎｄ　not enough scientists to observe all of them, they\'re asking fｏｒyour help in observing signs of climate change across the world. The citizen scientist movement encourages ordinary people too observe a very specific research interest-birds, trees, flowers budding, etc. ａｎｄ　send their observations to a giant ｄａｔａｂａｓｅ to be observed by professional scientists. This helps a small number of scientists track a large amount of data that they would never be able to gather on their own. Much like citizen journalists helping large publications cover a hyper-local beat, citizen scientists are ready fｏｒthe conditions where they live. All that\'s needed to become one is a few minutes each day ｏｒeach week to gather data ａｎｄ　send it in. Aｇｒｏｕｐof scientists ａｎｄ　educators launched an organization last year called the National Phenology Network. "Phenology" is what scientists call the study of the timing of events in nature. One of the group\'s first efforts relies on scientists ａｎｄ　non-scientists alike to collect data about plant flowering ａｎｄ　leafing every year. The program, called Project BudBurst, collects life cycle data on a variety of common plants from across the United States. People participating in the project which is open to everyone record their observations on the Project BudBurst website. "People don\'t have to be plant experts, they just have to look around ａｎｄ　see what\'s in their neighborhood," says Jennifer Schwartz, an education consultant with the project. "As we collect this data, we\'ll be able to make an estimate of how plants ａｎｄ　communities of plants ａｎｄ　animals will respond as the climate changes. "What are citizen scientists asked to do?【单选题】

A.To develop a specific research interest ａｎｄ　become professional scientists.

B.To send their research observations to a professional ｄａｔａｂａｓｅ.

C.To increase their knowledge about climate change.

D.To keep a record of their research observations.

正确答案:B

答案解析:根据send their observations to a giant ｄａｔａｂａｓｅ to be observed by professional scientists可知。

5、Better Control of TB Seen if a Faster Cure is FoundThe World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis. Most times, the infection remains inactive. But each year about eight million people develop active cases of TB, usually in their lungs. Two million people die of it. The disease has increased with the spread of AIDS ａｎｄ　drug-resistant forms of tuberculosis. Current treatments take at least six months. Patients have to take a combination of several antibiotic drugs daily. But many people stop as soon as they feel better. Doing that can lead to an infection that resists treatment. Public health experts agree that a faster-acting cure fｏｒtuberculosis would be more effective. Now a study estimates just how effective it might be. A professｏｒof international health at Harvard University led the study. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean fewer infectious patients who can pass on their infection to others. The researchers developed a mathematical model to examine the effects of a two-month treatment plan. They tested the model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. ａｎｄ　it might prevent about twenty-five percent of TB deaths. The model shows that these reductions would take place between two thousａｎｄ　twelve ａｎｄ　two thousａｎｄ　thirty. That is, if a faster cure is developed ａｎｄ　in wide use by two thousａｎｄ　twelve. The World Health Organization developed the DOTS program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make sure they continue treatment. Earlier this year, an international partnership of organizations announced a plan to expａｎｄ　the DOTS program. The ten-year plan also aims to finance research ______ new TB drugs. The four most common drugs used now are more than forty years old. The Global Alliance fｏｒTB Drug Development says its long-term goal is a treatment that could work in as few as ten doses.【单选题】

A.with

B.to

C.onto

D.into

正确答案:D
