For some people, the sight of a mouse can be reason to scream. For other mice, the same sight can be reason to sing.

    Mice will probably   21   sing their way to any concert, but researchers in the United States have found   22   that mice do,   23  , sing.

    Scientists already knew that mice make ultrasonic(超聲波) sounds—noises that are too high-pitched(高音的) for people to hear   24   special equipment.

    To find out whether mice put such sounds together in song-like   25  , the researchers recorded the sounds of 1 mice. Using computer   26  , they were able to separate the sounds into specific types of syllables(音節(jié)), and found the mice produced about 10 syllables per second.

    The results showed that nearly all of the mice repeated sequences(順序) of syllables in different patterns. That’s enough to meet the definition of what scientists   27   song. But not all scientists are   28  _ that what the mice are doing is   29   singing. To prove it, the researchers must show that there’s learning involved. And, they need to __  30   why the mice sing.

The Best of Friends

The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly held image (印象) of unhappy teenagers locked in their room after endless family quarrels.

An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past. “We were surprised by just how positive today’s young people seem to be about their families,” said one member of the research team. “They’re expected to be rebellious (叛逆的) and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There’s more negotiation (商議) and discussion between parents and children, and children expect to take part in the family decision-making process. They don’t want to rock the boat.”

So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me,” says 17-years-old Daniel Lazall. “I always tell them when I’m going out clubbing. As long as they know what I’m doing, they’re fine with it.” Susan Crome, who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”

Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion is not rooted in real facts. A researcher comments, “Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over.”

What is the popular image of teenagers today?

A. They worry about school.                  B. They quarrel a lot with other family members

C. They have to be locked in to avoid troubles.   . D. They dislike living with their parents.

The study shows that teenagers don’t want to ______.

A. share family responsibility              B. make family decisions

C. go boating with their family             D. cause trouble in their families

Compared with parents of 30 years ago, today’s parents______.

A. go to clubs more often with their children       B. give their children more freedom

C. care less about their children’s life             D. are much stricter with their children

According to the author, teenage rebellion ______.

 A. existed only in the 1960s                  B. is common nowadays

 C. may be a false belief                     D. resulted from changes in families

What is the passage mainly about?

A. Harmony in family.                         B. Education in family.

The Law to Keep the Oil Industry under Control

       The Norwegian Government is doing its best to keep the oil industry under control. A new law limits exploration to an area south of the southern end of the long coastline; production limits have been laid down (though these have already been raised); and oil companies have not been allowed to employ more than a limited number of foreign workers. But the oil industry has a way of getting over such problems, and few people believe that the Government will be able to hold things back for long. As on Norwegian politician said last week: “We will soon be changed beyond all recognition.”

       Ever since the war, the Government has been carrying out a programme of development in the area north of the Arctic Circle. During the past few years this programme has had a great deal of success: Tromso（特羅姆瑟[挪威北部港市]）has been built up into a local capital with a university, a large hospital and a healthy industry. But the oil industry has already started to draw people south, and within a few years the whole northern policy could be in ruins.

       The effects of the oil industry would not be limited to the north, however. With nearly 100 percent employment, everyone can see a situation developing in which the service industries and the tourist industry will lose more of their workers to the oil industry. Some smaller industries might even disappear altogether when it becomes cheaper to buy goods from abroad.

       The real argument over oil is its threat to the Norwegian way of life. Farmers and fishermen do not make up most of the population, but they are an important part of it, because Norwegians see in them many of the qualities that they regard with pride as essentially Norwegian. And it is the farmers and the fishermen who are most critical of the oil industry because of the damage that it might cause to the countryside and to the sea.

The Norwegian Government would prefer the oil industry to

A provide more jobs for foreign workers.

B slow down the rate of its development.

C sell the oil it is producing abroad.

D develop more quickly than at present.

The Norwegian Government has tried to

A encourage the oil companies to discover new oil sources.

B prevent oil companies employing people from northern Norway.

C help the oil companies solve many of their problems.

D keep the oil industry to something near its present size.

According to the passage, the oil industry might lead northern Norway to

A the development of industry.

B a growth in population.

C the failure of the development programme.

D the development of new towns.

In the south, one effect to the development of the oil industry might be

A a large reduction on unemployment.

B a growth in the tourist industry.

C a reduction in the number of existing industries.

D the development of a number of service industries.

Norwegian farmers and fishermen have an important influence because

A they form such a large part of Norwegian ideal.

B their lives and values represent the Norwegian ideal.

C their work is so useful to the rest of Norwegian society.

D they regard oil as a threat to the Norwegian way of life.

“Humans have a code of ethics (行為規(guī)范) ,” says Marc Bekoff, an animal behavior expert at the University of Colorado. “If I don’t play in a certain way, you won’t play with me. Some animals have the same code”

Scientists recently discovered that animals which live in groups, such as elephants, foxes and wolves are especially likely to follow rules. If they don’t, and each does its own thing, the group might break apart. Group members would be forced to live alone. Then they’d have a harder time hunting and raising their young.

That’s probably why a traveling wolf pack stopped and waited to let its slowly moving leader catch up. Similar social ties may have caused a captive elephant to save her friend from drowning. Selfish reasons certainly motivated the male fox, who wanted to keep playing.

Sometimes, though, animals go out of their way to do what’s right, even when there’s nothing in it for them. Nobody knows why. “It might simply feel good to be kind, just as it does for humans,” says Bekoff.

If your friend wasn’t nice to you, what would you do? Maybe you would just walk away. That’s exactly what a wild red fox did when she was play-boxing with another fox. The larger fox, a male, began pushing too hard. The little female didn’t like fighting. She ran away quietly.

“He still wanted to play,” says Marc Bekoff. So the male fox ran after his playmate, bowed down, and rolled over. His body language meant, “Don’t leave. I’ll play nicely.” The female gave him another chance, and the male wrestled more gently this time.

71 How did the little female fox show her dissatisfaction with the larger male one? (no more than 5 words)

Lose-Win is weak. It’s easy to get stepped on. It’s easy to be the nice guy. It’s easy to give in, all in the name of being a peacemaker.

     A girl named Jenny once told me about her  16  in the world of Lose-Win during her eighth-grade year before she finally broke  17 :

     My  18  with my mom all started one day  19  she said to me sarcastically (諷刺地) “Wow, you’re surely lively today.” I  20  it so literally (字面地) that then and there I decided to close off from her and never  21  back to her. So every time she would say something  22  I disagreed with her I would just say. “Okay, 23 you want, Mom.” But I really got cold quickly. And my 24 began to build. One night I talked to my mom about the school homework and she said, “Oh, that’s  25 ” and then went back to mop the floor.

     “Don’t you ever  26 ?” I thought. But I didn’t say anything and stormed off. She had no idea I was  27 upset. She would have been willing to talk to me had I  28  her bow important it was to me.

     At last I just blew up. “Mom, this has got to  29 . You tell me everything you want me to do and I just do it because it’s  30  than if fighting. Well, I’m sick of it.” This all came as a  31  to her.

     After my blow up, we felt like we were  32  all over in our relationship. But it’s getting better all the lime. We discuss things now and I always  33  my feelings with her.

     If you adopt Lose-Win as your basic  34  toward life, then people will wipe their dirty feet on you. You’ll also be  35  your true feelings deep inside. And that’s not healthy.
