题型:不详难度:来源:
Dolphins and sharks are showing up in surprisingly shallow
water just off the Florida coast. Mullets, crabs, rays and small
fish gather by the thousands off an Alabama pirer. Birds covered in
oil are crawling deep into marshes (沼泽), never to be seen again.
Marine scientists studying the effects of the BP disaster(英国石油公司漏油事件)are seeing
some strange phenomena. Fish and other wildlife seem to be fleeing the oil out in the Gulf and clustering in cleaner waters along the coast in a trend that some researchers see as a potentially troubling sign. The animals" presence close to shore means their usual habitat is badly polluted, and the crowding could result in mass die-offs as fish run out of oxygen. Also, the animals could easily be captured by their enemies.
The nearly two-month-old spill(漏油)has created an environmental disaster in US history as tens of millions of gallons have flown into the Gulf of Mexico ecosystem. Scientists are seeing some unusual things as they try to understand the effects on thousands of species of marine life.
For nearly four hours Monday, a three-person crew with Greenpeace cruised past delicate
islands and mangrove-dotted inlets in Barataria Bay off southern Louisiana. They saw dolphins by the dozen frolicking(嬉戏)in the oily sheen(光泽)and oil-tinged pelicans feeding their young. But they spotted no dead animals.
"I think part of the reason why we"re not seeing more yet is that the impacts of this crisis are
really just beginning," Greenpeace marine biologist John Hocevar said.
The counting of dead wildlife in the Gulf is more than an academic exercise; the deaths will
help determine how much BP pays in damages.

Which gender is the most talkative? No matter what you answer, you are partially right.
A recent Gallup Poll showed that both men and women believe that women possess the gift of talking and some even believe women are biologically built for conversation, but all of that is challenged in a research published in the November issue of Personality and Social Psychology Review.
In a recent research by Campbell Leaper and Melanie Ayres, they collected all of the available evidence from decades of scientific study and systematically combined the findings into an overall picture of the differences between men and women regarding talkativeness.
They found a small but reliable tendency(趋势) for men to be more talkative than women in certain cases, such as when they were conversing with their wives or with strangers. Women talked more to their children and to their college classmates.
The type of speech was also explored in the research. The researchers discovered that, with strangers, women were generally more talkative when it came to using speech to ensure her connection to the listener, while men’s speech focused more on an attempt to influence the listener. With close friends and family, however, there was very little difference between genders in the amount of speech.
60.This passage mainly talks about a research conducted by _______ .
A. Gallup Poll       B. Personality and Social Psychology Review

B. Men are born more talkative than women.
C. Women and men are talkative in different cases.
D. Women are no more talkative than men.
62.The underlined word gender means _______.
A. people       B. nationality  C. culture       D. sex
63.Talking with strangers, ________.
A. women are more talkative than with people they know
B. men are more talkative than with their wives
C. women prefer to listen more rather than speak more
D. men speak a lot to have their opinions accepted

Books are not Nadia Konyk"s thing. Her mother brings them home from the library, but Nadia rarely shows interest. Instead, like so many other teenagers, Nadia, 15, is addicted to the Internet. She regularly spends at least six hours a day in front of the computer, spending most of her time reading and commenting on stories written by other users. Her mother, Deborah Konyk, would prefer that Nadia read books for a change.
As teenagers" scores on reading tests have declined, some argue that the hours spent surfing the Internet are the enemy of reading—destroying a precious common culture that exists only through the reading of books. Critics have warned that electronic media would destroy reading.
Others say the Internet has created a new kind of reading. The Web inspires a teenager like Nadia, who might otherwise spend most of her leisure time watching television, to read and write. What is different now, some literacy experts say, is that spending time on the Web engages viewers with text.
Web supporters believe that strong readers on the Web may eventually surpass those who rely on books. Reading five Web sites, experts say, can be more enriching than reading one book. "It takes a long time to read a 400-page book," said Spiro. "In a tenth of the time," he said, the Internet allows a reader to "cover a lot more of the topic from different points of view."
Some literacy experts say that reading itself should be redefined. Interpreting videos or pictures, they say, may be as important a skill as analyzing a novel or a poem. "Kids are using sound and images so they have a world of ideas to put together," said Donna Alvermann, a professor of literacy education at the University of Georgia. "Books aren"t out of the picture, but they"re only one way of experiencing information in the world today."
Next year, the Organization for Economic Cooperation and Development, which gives reading, math and science tests to 15-year-old students in more than 50 countries, will add an electronic reading component(软件). The United States says it will not participate because an additional test would overburden schools.
小题1:Why are books not the thing of Nadia Konyk?
A.She does reading mainly through electronic media.
B.Her mother doesn’t provide her with enough books.
C.She has become addicted to playing games on the web.
D.Like many youngsters, she has lost interest in reading.
小题2:How many hours does Nadia spend in front of the computer in a week?
A.Exactly forty-two hoursB.Usually fifty hours
C.More than forty hoursD.At most thirty-six hours
小题3:Which of the following statements is correct according to the passage?
A.To search for information on the web engages viewers without text.
B.To explain videos is a technique more important than analyzing a novel.
C.Children using sound and images may lose their interest in movies.
D.People reading well online may surpass those who rely on books.
小题4:Why did the US refuse to participate in the tests with an added electronic reading component?       It is because ______.
A.the teachers and students considered it useless
B.such a test would give schools more extra work
C.they thought reading was the only way to get information
D.none of them showed interest in such an additional test

Experts say the American state of Hawaii has been invaded (入侵)by a small frog called the coqui (ko--kee). There may be millions of the small frogs in Hawaii. However, they do not belong there. They are normally found in the southeastern United States. The coqui frogs are harming Hawaii’s environment. And the extremely loud noise they make is causing problems for Hawaiian citizens and visitors.
The coqui invaders arrived in Hawaii about ten years ago. They were believed to have been brought in accidentally in shipments of plants from Florida. Their number has sharply increased. They have quickly spread around the Hawaii Islands hidden in plants.
The coqui is a brown frog about five centimeters long. During the day, the frogs hide in wet protected areas, such as under plant leaves. At night, the frogs move onto trees to feed, call to females and mates. The call of the male coqui sounds like. Ko kee! Ko kee!
In the southeastern United States, local people celebrate coqui frogs. But in Hawaii, the foreign frog has been considered as a harmful animal. The coqui frogs are a major danger to Hawaii’s environmental system. The frogs eat thousands of insects (昆虫)every night. These insects are important for the reproduction of plants. The insects also are important food for Hawaii’s native rare birds. The frogs also are affecting the tourism industry in Hawaii. Increasing numbers of hotels, visitors and local people have been annoyed by the loud calls made by male coqui frogs to female frogs. At night, the noise often makes it difficult for people to sleep.
The frogs do not have any natural enemies in Hawaii to reduce their population size. The warm weather permits them to lay eggs all year long. There are many efforts in Hawaii designed to stop the spread of the coqui. It is a crime to transport ,sell or release(释放)the frogs there.
The Hawaii Department of Agriculture is trying to find an effective chemical that can be safely used to kill the frogs. For now, the frogs may only be caught by hand. The Hawaii Department of Agriculture says the greatest danger to the economy and environment of the state is from harmful species, like the coqui.
小题1:The statement that can best summarize the main idea of the passage is         .
A.the coqui invaders have seriously affected the tourism industry in Hawaii
B.it is not permitted to transport, sell or release the coqui frogs in Hawaii
C.the coqui invasion has serious effects on the economy and environment in Hawaii
D.great efforts have been made by the Hawaii people to kill the coqui
小题2:The coqui frogs originally arrived in Hawaii            .
A.by chanceB.at the request of all the local citizens
C.as a giftD.as goods demanded in the local market
小题3:Visitors to Hawaii don’t like the coqui frogs mainly because                 .
A.they are a big danger to the environmental system there
B.the loud noise made by the frogs bother their rest at night
C.they affect the reproduction of the local plants and insects
D.visitors could no longer see the native rare birds because of them
小题4:The two factors leading to the rapid spread of coqui frogs in Hawaii are           .
A.the frogs’ habit and the environment in Hawaii
B.the large number of the insects and the plants in Hawaii
C.the geographic location of Hawaii and its tourism industry
D.the warm weather there and the frogs’ lack of natural enemies

Teaching includes more than leadership. Some of the teacher"s time and effort is directed toward instruction, some toward evaluation(评价). But it is the teacher as a group leader who creates an effective organizational structure and good working environment so that instruction and evaluation activities can take place. A group that is totally disorganized, unclear about its goals, or constantly fighting among its members will not be a good learning group. The leadership pattern includes helping to form and keep up a positive learning environment so that instruction and evaluation activities can take place.
On the first day of class the teacher faces a room filled with individuals. Perhaps a few closely united groups and friendships already exist. But there is no sense of belonging. If teachers are successful leaders, they will help students develop a system of relationships that encourages cooperation.
Standards and rules must be set up that keep order, ensure justice, and protect individual rights, but are not against school policy. What happens when one student hurts another"s individual rights? Without clear guidelines agreeable to students, teachers, and administration(行政管理), the classroom can be in disorder. Students may break rules they did not know existed. If standards are set without opinions from the class, students may spend a great deal of creative energy in ruining the class environment, finding ways to break rules.
No matter how skillful the teacher is in uniting students and setting up a positive atmosphere, the task is never complete. Regular maintenance(保持) is necessary. Conflicts(冲突) arise. The needs of individual members change. A new kind of learning task requires a new organizational structure. Sometimes out pressures such as holidays, upcoming tests or athletic contests, or family troubles cause pressure in the classroom. One task for the teacher is to bring back a positive environment by helping students deal with conflicts, changes and pressure.
