【题目】Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)-either recorded or real-may even prevent elephants from damaging farmer's crops.

In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.

Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. NextLucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family.

From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.

Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.

【题目】What did your school smell like? Was it noisy or peaceful? It might not seem important, but a growing body of research suggests that smells and sounds can have an impact on learning, performance and creativity.

Bridget Shield has been conducting studies and advising people on the effects of all sorts of noises, such as traffic and sirens, as well as noise made by the children themselves. "Everything points to a harmful impact of the noise on children’s performance, in numeracy, in literacy, and in spelling,” says Shield.

Shield says the sound of “babble” the chatter of other children, is particularly distracting in the classroom.。People are very distracted by speech-particularly if it is understandable, but you’re not involved in it.” This phenomenon is also known as the irrelevant speech effect, she says, adding that “it’s a very common finding in open-plan offices as well.’’

In a series of studies published last year, Ravi Mehta found that people were more creative when the background noises were played at a medium level than when volume was low. Loud background noise, however, damaged their creativity. Ravi Mehta suggests there maybe some benefit to playing music or other sounds in an art class or other situations where creativity is the key.

Many teachers all over the world already play music to students in class. Many are inspired by the belief that hearing music can boost IQ in their tasks, the so-called Mozart effect. While the evidence actually suggests it’s a guess to say classical music boosts brainpower, researchers do think pleasant sounds before a task can sometimes lift your mood and help you perform well, says Ravi Mehta," If you like the music or you like the sound-even listening to a Stephen King novel-then you did better. It didn’t matter about the music,“ he says.

However, it’s worth considering that music is not always helpful while you’re trying to work. Trying to perform a task which involves serial recall - for instance, doing mental mathematics-will be distracted by sounds with audio variation, says Ravi Mehta. Songs with lyrics, on the other hand, are more likely to interfere(干扰)with tasks that involve languages-such as reading comprehension.

This isn’t the only sense being related to affecting learning.

1The second paragraph implies that _________.

A.general noise also has a harmful effect.

B.students are sensitive to noise.

C.some children need special sounds to do tasks.

D.children aren't affected by their own noise.

2The irrelevant speech effect refers to the fact that _________.

A.you don’t understand what others are talking

B.you are interrupted by the chatting of others

C.you are unwilling to chat with other people

D.you find what others are talking irrelevant to you

【题目】In American high schools, there is a tradition for each year's graduating class( called the seniors) to play a joke on the schoolthe Senior Prank(毕业恶作剧).

This usually happens at the end of the school year just before the seniors graduate from the school. It is an unofficial tradition. Al-though the schools don't encourage it, each year the seniors try to make their pranks the most original so that their class will be remembered in the years to come. The joke is supposed to be light-hearted(无伤大雅的)and must not do major damage to the school property .

The best prank at my high school was done several years ago. A flower called the golden poppy(金罂粟花)is the state flower of California ; the state law states that no one can cut them down once they are planted.

The seniors at my school took advantage of the law. They planted golden poppies all over the football field one night, spelling out their graduation year with the flowers ! Since the school couldn't break the law to cut down the poppies, they had to wait until the flowers died.

The greatest prank that I've ever heard was done by one of my history teachers when he was in high school. He and some of his close friends went fishing in hopes of catching big fish for their prank. They were lucky and caught a three-foot shark.

My teacher and his friends took the shark to the school at night and dumped it into the swimming pool. The next morning when students went swimming, they found a dead shark in their pool. The chlorine()in the water had killed the shark ! My history teacher always regretted that his school had put so much chlorine in the pool, or it would have been more fun if the shark was still alive the next day.

The schools won't take it seriously if the pranks don't cause too much damage. But, sometimes the school will punish the seniors for going too far with their prank. My teacher's “Shark Prank “is an example of a prank gone too far. The school had to drain (排水)the pool and have it cleaned before filling it up again, which had cost the school several thousand dollars.

【1】 The underlined word “property “means _________.

A. 资产 B. 性质 C. 道具 D. 所有权

【2】 The author implies (暗示)_________.

A. the schools encourage the seniors to play the prank

B. his history teacher was punished by the school

C. the law of California doesn't allow planting the golden poppy in the campus

D. after finding a shark in the swimming pool, the school killed it with the chlorine

【3】 We can infer(推断)from the passage that _________.

A. the “Golden Poppy Prank “is successful and well-meaning

B. the Senior Prank is an unofficial tradition

C. the school had to cut down the golden poppies at last

D. the golden poppy is the state flower of California

【4】 Which of the following is not mentioned in the passage?

A. Only the graduating class can play the Senior Prank.

B. The schools don't encourage the Senior Prank.

C. The “Golden Poppy Prank " cost the school a lot of money.

D. The “Shark Prank “is beyond the general pranks.
