　　More than half of teachers in a UK survey said they thought plagiarism from the Internet is a problem.

　　Some students who steal essays (论文)wholesale from the Web, they said, are so lazy they don't even bother to take the advertisements off the cut-and-pasted text.

　　Fifty-eight percent of the teachers interviewed in the Association of Teachers and Lecturers (ATL) questionnaire had come across plagiarism among their pupils.

　　Gill Bullen from Itchen College in Southampton said, "pieces handed in by two students were identical (同样的) and significantly better than either of them could have done."，"Not only that, the essays handed in didn't quite answer the title question I had set."

　　A teacher from Leeds said, "I had one piece of work so blatantly (明目张胆地) 'cut and pasted' that it still contained adverts from the Web page."

　　Connie Robinson from Stockton Riverside College, Stockton, said, "With less able students it is easy to spot plagiarism as the writing style changes mid-assignment, but with more able students it is sometimes necessary for tutors to carry out Internet research to identify the source of the plagiarism."

　　Mary Bousted, general secretary of the ATL, said, "Teachers are struggling under a mountain of cut-and-pasting to spot (看出) whether work was the student's own or plagiarism."

　　She called for robust policies to combat plagiarism, and asked for help from exam boards and the government in providing resources and techniques to detect cheats.

　　But there was another side.

　　"I have found once students clearly understand what plagiarism is, its consequences and how to reference correctly so they can draw on published works, plagiarism becomes less of a problem," said Diana Baker from Emmanuel College, Durham.

　　"I think the majority of students who engage in plagiarism do it more out of ignorance (出于无知) than the desire to cheat. They really want to succeed on their own merit."

　　29. Gill Bullen’s words show that ▲ .

　　A. students can write their own homework easily

　　B. students didn’t write the essays themselves properly

　　C. the essays matched the title question correctly

　　D. students can do better than they have expected

　　A. It is easy for teachers to recognize (识别) plagiarism.

　　B. The assignments handed in by two students may be identical.

　　C. Teachers know whether the work is the student’s work or plagiarism.

　　D. A large number of students don’t know that plagiarism is cheating.

　　31. According to Paragraph 2 some students are so lazy that they don’t ▲ .

　　A. bother to remove the advertisements

　　B. want to steal the whole essay

　　C. check the mistakes on the Internet

　　D. bother to do the work of cutting and pasting

　　Which part of the world has the most nearsighted students? Just look around you–it’s East Asia. Nine in ten school leavers in major East Asian cities are nearsighted, according to the BBC. Experts say books and video games are not to blame. East Asian students, they say, aren’t getting enough sunlight.

　　People become nearsighted because their eyeballs grow out of shape and light entering their eyes cannot focus correctly. The body can produce a chemical called dopamine (多巴胺) to stop eyeballs from changing shape. And guess what scientists have just discovered? Sunlight can help our bodies produce more dopamine, reported AFP.

　　According to the study, primary school students in Singapore spend only 30 minutes outdoors every day; in Australia, by contrast, kids spend about three hours a day outside. As a result, fewer children in Australia are nearsighted–only 10 percent, compared with 90 percent in Singapore.

　　“Children in East Asia basically go to school，go home and stay inside. They study and they watch television,” Ian Morgan of the Australian National University told AFP.

　　But being a bookworm or a couch potato does not directly harm the eyes, added Morgan. “As long as they get outside, it doesn’t seem to matter how much study they do,” he explained. “There are some kids who study hard and get outside and play hard and they are generally fine. The ones who are at major risk are the ones who study hard and don’t get outside. As a result of massive (巨大的) educational pressures and the construction (构成) of a child’s day, the amount of time they spend outside in bright light is “minimized.”

　　Experts suggest children should stay outside for two to three hours every day. This can include time spent in the playground and walking to and from school.

　　32. What is the main reason for the large number of nearsighted students in East Asia, according

　　to scientists?

　　A. Too much reading or gaming. B. Lack of sunlight.

　　C. Genetic reasons. D. Lack of exercise.

　　33. What can we learn from Paragraph 2?

　　A. Dopamine is a chemical that causes eyeballs to grow out of shape.

　　B. Dopamine can stop light entering the eyes from focusing correctly.

　　C. Spending time in the sun can make the loss of dopamine in the body.

　　D. The more dopamine a person has in their body, the better eyesight he or she has.

　　34. According to Morgan, what kind of people are most likely to suffer from nearsightedness?

　　A. Those who like watching TV.

　　B. Those who take exercise regularly.

　　C. Those who study hard and play hard outdoors.

　　D. Those who stay indoors studying all day.

　　35. The word “minimized” probably means “ ▲ ”.

　　A. reduced as much as possible B. made better use of

　　C. taken little notice of D. attached much importance to
