Most people think of zoos as safe heavens for animals, where problems such as difficulty finding food and avoiding predators (食肉動物) don’t exist. Therefore, animals in zoos should live to a ripe old age.
But that may not be true for the largest land animals on earth. Scientists have known that elephants in zoos often suffer from poor health. They develop diseases and they are even unable to have babies.
To learn more about how captivity (圈養) affects elephants, a team of international scientists compared the lifespans (壽命) of the zoo-born elephants with the lifespans of thousands of wild elephants. They also compared some Asian elephants living in zoos with some Asian elephants which work in logging camp (伐木場), over almost the same time period.
The team found that elephants born in zoos lived an average of 16.9 years, but elephants that died of natural causes lived an average of 56 years. Asian elephants followed a similar pattern. In zoos, they lived 18.9 years, while those in the logging camp lived 41.7 years.
Scientists don’t yet know why wild elephants seem to live so much better than their zoo-raised counterparts (同類). Georgia Mason, a biologist at the University of Guelph in Canada, who led the study, thinks stress and obesity (肥胖) may be to blame. Zoo elephants don’t get the same kind of exercise they would in the wild. Elephants’ social lives are also much different in zoos than in the wild, where they live in large family groups.

A．animals in zoos should live a longer life

A．to compare the lifespans of different animals

小題3:Which elephants live the longest according to the study?

A．Elephants born in zoos.

B．Elephants that live in the wild.

C．Elephants that work in logging camps.

D．Female Asian elephants in logging camps.

In 1879, a group of explorers made an incredible find. They discovered paintings of remarkable beauty on the walls of a cave in Spain. Some scientists believed that these paintings were created by early humans from the Stone Age, between ten and thirty thousand years ago. Other scientists and the public did not believe the claim, but over the years, it was proven correct. Our ancestors had incredible artistic talents.
Most of the cave art that has been discovered has been found in Spain and France. A smaller number of such caves are located in Italy, Portugal, Russia, and other countries. Scientists believe that many more caves will be discovered in the coming years, and are concentrating their efforts on Africa and the area between Europe and Asia. These two regions of the world were, populated first by humans.
Cave art was carved or painted on the walls and roofs of caves, usually near the entrance. The entrance area was probably chosen to take advantage of daylight and to allow many people to view the paintings. In some cases, the art appears much deeper in caves and requires artificial light. Evidence suggests that the artists used torches or shallow bowls in which animal fat was burned.
9.What was the response of general public to the discovery of cave art made by Stone Age people?
A. They believed it at first.
B. They did not believe it.
C. They thought it was beautiful.
D. They ignored it.
10.According to the passage, what can we conclude about animal fat?
A. It does not burn.
B. Stone Age artists used it to preserve their paintings.
C. It can be burned to produce light.
D. Stone Age artists mixed it with their food.
11.. Where do scientists expect to find more cave paintings?
A. In Central and South America.
B. In Spain and France.
C. In the places where there are caves with large openings.
D. In the regions of the world first populated by humans.
12.Where would this passage be most likely to appear?
A. In a textbook about early human history.
B. In a textbook about modern art.
C. In a dictionary.
D. In an encyclopedia entry about caves.

I fell in love with England because it was quaint (古色古香的)—all those little houses, looking terribly old fashioned but nice, like doll’s house. I loved the countryside and the pubs, and I loved London. I’ve slightly changed my mind after seventeen years because I think it’s an ugly town now.
Things have changed. For everybody, England meant gentleman, fair play, and good manners. The fair play is going, unfortunately, and so are the gentlemanly attitudes and good manners—people shut doors heavily in your face and politeness is disappearing.
I regret that there are so few comfortable meeting places. You are forced to live indoors. In Paris I go out much more, to restaurants and nightclubs. To meet friends here usually has to be in a pub, and it can be difficult to go there alone as a woman. The cafes are not terribly nice.
As a woman, I feel unsafe here. I spend a bomb on taxis because I will not take public transport after 10 p.m. I used to use it, but now I’m afraid.
The idea of family seems to be more or less non-existent in England. My family is well united and that’s typically French. In Middleses I had a neighbor who is 82 now. His family only lived two miles away, but I took him to France for Christmas once because he was always alone.
小題1:The writer doesn’t like London because she___________.
A. is not used to the life there now
B. has lived there for seventeen years
C prefers to live in an old-fashioned house
D. has to be polite to everyone she meets there
小題2: Where do people usually meet their friends in England?

A．In a café

B．In a restaurant

C．In a nightclub

D．In a pub

小題3:The underlined word “it” in Para.4 refers to__________.

A．a taxi

B．the money

C．a bomb

D．public transport

小題4:The writer took her neighbor the France for Christmas because she__________.

A．felt lonely in England	B．had never been to France
C．was from a typical French family	D．didn’t like the British idea of family

For many years, I was convinced that my suffering was due to my size. I believed that when the weight disappeared, it would take old wounds, hurts, and rejections with it.
Many weight－conscious people also mistakenly believe that changing our bodies will fix everything. Perhaps our worst mistake is believing that being thin equals being loved being special, and being cherished. We fantasize about what it will be like when we reach the long－awaited goal. We work very hard to realize this dream. Then, at last, we find ourselves there.
But we often gain back what we have lost. Even so, we continue to believe that next time it will be different. Next time, we will keep it off. Next time, being thin will finally fulfill its promise of everlasting happiness, self－worth, and, of course, love.
It took me a long while to realize that there was something more for me to learn about beauty. Beauty standards vary with culture. In Samoa a woman is not considered attractive unless she weighs more than 200 pounds. More importantly, if it’s happiness that we want, why not put our energy there rather than on the size of our body? Why not look inside? Many of us strive hard to change our body, but in vain. We have to find a way to live comfortably inside our body and make friends with and cherish ourselves. When we change our attitudes toward ourselves, the whole world changes.
小題1:The passage tries to highlight the importance of _________.

A．body size	B．attitudes toward life
C．culture difference	D．different beauty standards

小題2:What does the word “everything” in paragraph 2 mean?

A．All the problems.	B．All the properties.
C．The whole world.	D．The absolute truth.

小題3:What can be inferred about the author?

A．The author is a Samoan.

B．The author succeeded in losing weight.

C．The author has been troubled by her/ his weight.

D．The author probably got wounded in wars or accidents.

小題4:According to the author, what is the common view of those who have lost some weight first and gained it back later?

A．They feel angry about the regained weight.

B．They are indifferent to the regained weight.

C．They feel optimistic about future plans on weight control.

D．They think they should give up their future plans on weight control.

A year ago, I paid no attention to English idioms, though my teacher emphasized(強調) the importance again and again. But soon, the importance of English idioms was shown in an amusing experience.
One day, I happened to meet an Englishman on the road, and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be astonished. Gently shaking his head, shrugging his shoulders, he said, “You don’t say!” “You don’t say!” I was puzzled. I thought, perhaps this is not an appropriate topic(適當的話題). “Well, I’d better change the topic.” So I said to him. “Well, shall we talk about the Great Wall? By the way, have you ever been there?” “Certainly, everyone back home will laugh at me if I leave China without seeing it. It was magnificent.” He was deep in thought when I began to talk like a tourist guide. “The Great Wall is one of the wonders in the world. We are very proud of it.” Soon I was interrupted again by his words：“You don’t say!” I couldn’t help asking, “Why do you ask me not to talk about it?” “Well, I didn’t request you to do so, ” he answered, greatly surprised. I said, “Didn’t you say’ you don’t say？” Hearing this, the Englishman laughed to tears. He began to explain, ‘You don’t say’ actually means ‘really!’ It is an expression of surprise. Perhaps you don’t pay attention to English idioms.” Only then did I know I had made a fool of myself. Since then I have been more careful with idiomatic expressions. Remember: what the English teachers said is always right to us students.
小題1:A year ago, I paid no attention to English idioms because _______.

C．I had talked too much

D．I had to stop talking

小題3:The underlined word in the first paragraph probably means _______.

A．interesting	B．important
C．terrible	D．unlucky

小題4:Which of the following is true according to the passage？

A．The Englishman left China without seeing the Great Wall.

B．The Englishman wanted to see the Great Wall after I talked about it.

C．The Englishman wanted me to act as his guide.

After sunset on our last day at the farm I walked out into the desert. In this, the first pleasant moment for a walk after long hot hours, I thought I was the only thing out of doors. Suddenly I stopped. Before me a rattlesnake lay fixed, its head not yet drawn back to strike but only turned a little to watch what I would do. Many snakes will run away at the sight of a man but this rattlesnake felt no necessity to get out of any-body's way. He held his ground in calm watch-fullness waiting for me to show my intentions. My first aim was to take no notice of him; I had never killed an animal if I was not forced to kill. But I remembered that there were children, dogs and horses at the farm as well as men and women with thin clothes on; my duty was to kill the snake. I went back to the farm and returned with a stick. The rattlesnake had not moved; he lay like a wire but more quickly than I could stride he shot into a bush and set up his rattling, warning me by this that I had made an unreasonable attack and attempted to take his life and that if I insisted he would have no choice but to take mine if he could. For a moment I listened to this terrifying sound and then I struck into the bush with my stick and, chop-ping about, dragged him out of the bush with his back broken.
He struck once more at the stick but a moment later his neck was broken and he was soon dead although when I picked him up by the tail his mouth opened, proving that a dead snake may still bite. There was blood in his mouth and poison was dropping; it was not only a dis-gusting(令人作嘔的) sight but a pitiful one too. I dropped the body into a green bush and, as I did so, I saw him in my imagination, crawling over the sands as he might have done if I had let him go.
小題1:At the sight of the author, the rattlesnake .

A．shot into a bush

B．lay motionless but got ready to meet danger

C．drew itself up to strike

D．took no notice of his presence

小題2:The author had to kill the rattlesnake because .

A．it stood in his way

B．it attempted to take his life

C．it presented a disgusting sight

D．its presence was a danger to the people and animals at the farm

小題3:Which of the following best describes the rattlesnake?

A．It attacked man without any reason.

B．It would not attack unless it was attacked.

C．It ran away at the sight of man.

D．It exposed itself to danger.

小題4:It is implied at the end of the passage that the author____.

A．regretted having killed the snake

B．was glad that he had killed the snake

C．felt a little sorry for the snake

D．could not help thinking about the dead snake

I was bleeding now. My ears were red, my nose was broken, and the pain of failure was beginning. I had lost. It was over. The match was stopped. The world seemed to stand still for a moment as I looked at who had beaten me. “I’ve lost,” I said in m mind. “The last chance to win and I had lost.” It was the final round of wrestling. It was my last year at camp and I wanted to have an undefeated season. But now, I had lost in the tournament（錦標賽）.
My coach came over to help me up. He saw that my nose was broken and realized that the match had to be stopped. He helped me up and I got small applause from my teammates. People on the other team just stared. Coach walked me over to the locker room to work on my nose.
“I’ll stop the bleeding,” Coach Matt said. His voice was cold and empty. He had expected me to win—he knew I could have won—but now he saw it was over. I had lost.
“Hey, Steve. You did good, man, He, well, he just…” my friend Paul couldn’t find what to say.
“Forget it, man.” I said, my nose still bleeding.
“Don’t talk or it won’t stop bleeding. Just relax and breath through your mouth.” Coach Matt’s voice was still cold, but warming slowly. He was like a father to me. He had been there through all my years of wrestling, all my wins and losess , all my hopes and dreams—and now he was there, fixing my smashed nose.
“This must have happened during that last throw. You fell too much on your face. You should’ve turned and tried to escape. You gotta think more.” Coach Matt began, his voice now warm like an old friend trying to give good advice.
“I wanted this so badly.” I said.
“Maybe we can get another contest because of the nose. You can still go undefeated! You can still do it…” Paul continued.
No, I lost. Nothing was left for me to do this year. This was supposed to be the year—no loses.” I said, cutting him off before he finished.
“Steve, you did your best. Come on. Let’s go and get your medal,” Coach said. He looked at me right in the eyes. “You gave it your all. You deserved that trophy(戰利品), not the silver medal. You deserve it, but he is getting it. You really won and the whole team is proud.”
I walked up to get my medal, my head held high. I shook the hands of the judges and my opponent, took m medal and saw that, in the eyes of everyone, I had really won. No matter what trophy or medal my opponent took home, no matter what. He may have had my trophy, but he could never have my will.
