第二部分阅读理解(共两节,满分50分)

第一节阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出

最佳选项,并在答题卡上将该项涂黑。(共20小题;每小题2分,共40分)

A

It was a winter morning, just a couple of weeks before Christmas 2005. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.

The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries(食品杂货),saving us from having to walk long distances from where we live.

I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.

People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience

has had a spreading effect in our lives because it strengthened our faith in humanity(人性)as a whole. And it has influenced(影响)us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.

41. Why was the bike so important to the couple?

A. The man’s job was bike racing.

B. It was their only possession.

C. It was a nice Kona 18 speed.

D. They used it for work and daily life.

42. We can infer from the text that ____________.

A. the couple worked 60 hours a week.

B. people were busy before Christmas

C. the stranger brought over the bike

D. life was hard for the young family.

43. How did people get to know the couple’s problem?

A. From radio broadcasts.

B. From a newspaper.

C. From TV news.

D. From a stranger.

44. What do the couple learn from their experience?

A. Strangers are usually of little help.

B. One should take care of their bike.

C. News reports make people famous.

D. An act of kindness can mean a lot.

B

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.

Although there are many different types of food, some animals spend their lives eating only one type. The giant panda(大熊猫)eats only one particular type of bamboo(竹子). Other animals eat only one type of food even when given the choice. A kind of white butterfly(蝴蝶)will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet(多样化饮食). The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.

Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much

sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.

45. We can infer from the text that humans and animals _________.

A. depend on one sense in choosing food

B. are not satisfied with their food

C. choose food in similar ways

D. eat entirely different food

46. Which of the following eats only one type of food?

A. The white butterfly.

B. The small bird.

C. The bear.

D. The fox.

47. Certain animals change their choice of food when ___________.

A. the season changes

B. the food color changes

C. they move to different places

D. they are attracted by different smells

48. We can learn from the last paragraph that __________.

A. food is chosen for a good reason

B. French and British food is good

C. some people have few choices of food

D. some people care little about healthy diet C

It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can’t fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.

Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He

thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain. Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys’ blood back to the monkeys’ brains. When the brain’s temperature was 10℃, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.

49.The biggest difficulty in operating on the damaged brain is that ____.

A. the time is too short for doctors

B. the patients are often too nervous

C. the damage is extremely hard to fix

D. the blood-cooling machine might break down

50.The brain operation was made possible mainly by ____.

A. taking the blood out of the brain

B. trying the operation on monkeys first

C. having the blood go through a machine

D. lowering the brain’s temperature

51.With Dr. White’s new idea, the operation on the damaged brain ____.

A. can last as long as 30 minutes

B. can keep the brain’s blood warm

C. can keep the patient’s brain healthy

D. can help monkeys do different jobs

52.What is the right order of the steps in the operations?

a. send the cooled back to the brain

b. stop the blood to the brain

c. have the blood cooled down

d. operate on the brain

A. a, b, c, d

B. c, a, b, d

C. c, b, d, a

D. b, c, d, a

Lying in the sun on a rock, the cougar(美洲豹)saw Jeb and his son, Tom before they saw it. Jeb put his bag down quickly and pulled his jacket open with both hands, making himself look big to the cougar, It worked. The cougar hesitated, ready to attack Jeb, but ready to forget the whole thing, too.

Jeb let go of his jacket, grasped Tom and held him across his body, making a cross. Now the cougar’s enemy looked even bigger, and it rose up, ready to move away, but unfortunately Tom got scared and struggled free of Jeb.

―Tom, no‖ shouted his father.

But Tom broke and ran and that’s the last thing you do with a cougar. The second Tom broke free, Jeb threw himself on the cougar, just as it jumped from the rock. They hit each other in mid-air and both fell, The cougar was on Jeb in a flash, forgetting about Tom, which was what Jeb wanted.

Cougars are not as big as most people think and a determined man stands a chance, even with just his fists. As the cougar’s claws(爪子)got into his left shoulder, Jeb swung his fist at its eyes and hit hard. The animal howled(吼叫)and put its head back. Jeb followed up with his other fist. Then out of the corner of his eye. Jeb saw Tom. The boy was running back to help his father.

―Knife, Tom,‖ shouted Jeb.

The boy ran to his father’s bag, while Jeb started shouting as well as hitting, to keep the cougar’s attention away from Tom. Tom got the knife and ran over to Jeb. The cougar

was moving its head in and out, trying to find a way through the wall Jeb was making out of his arms. Tom swung with the knife ,into the cougar’s back. It howled horribly and ran off into the mountains.

The whole fight had taken about thirty seconds.

53.Why did Jeb pull his jacket open when hesaw the cougar?

Hunting

The days of the hunter are almost over in India. This is partly because there is practically

nothing left to kill, and partly because some steps have been taken, mainly by banning tiger-shooting, to protect those animals which still survive.

Some people say that Man is naturally a hunter. I disagree with this view. Surely out earliest forefathers, who at forest possessed no weapons, spent their time digging for roots, and were no doubt themselves often hunted by meat-eating animals.

I believe the main reason why the modern hunter kills is that he thinks people will admire his courage in overpowering dangerous animals. Of course, there are some who truly believe that the killing is not really the important thing, and that the chief pleasure lies in the joy of the hunt and the beauties of the wild countryside There are also those for whom hunting in fact offers a chance to prove themselves and risk death by design; these men go out after dangerous animals like tigers, even if they say they only do it to rid the countryside of a threat. I can respect reasons like these, but they are clearly different from the need to strengthen your high opinion of yourself.

The greatest big-game hunters expressed in their writings something of these finer motives(动机).One of them wrote.

―You must properly respect what you are after and shoot it cleanly and on the animal’s own territory(领地)。You must fix forever in your mind all the wonders of that particular day. This is better than letting him grow a few years older to be attacked and wounded by his own son and eventually eaten, half alive, by other animals, Hunting is not a cruel and senseless killing – not if you respect the thing you kill, not if you kill to enrich your memories, not if you kill to feed your people.‖

I can understand such beliefs, and can compare these hunters with those who hunted

lions with spears(矛) and bravely caught them by the tail. But this is very different from many tiger—shoots I have seen, in which modern weapons were used. The so—called hunters fired from tall trees or from the backs of trained elephants. Such methods made tigers seem no more dangerous than rabbits.

57.Theere is no more hunting in India now partly because___.

A. it is dangerous to hunt there

B. hunting is already out of date

C. hunters want to protect animals

D. there are few animals left to hunt

58.The author thinks modern hunters kill mainly____.

A. to make the countryside safe

B. to earn people’s admiration

C. to gain power and influence D .to improve their health

59.What do we learn about the big-game hunters?

A. They hunt old animals

B. They mistreat animals

C. They hunt for food

D. They hunt for money

60.What is the author’s view on the tiger-shoots he has seen?

A. Modern hunters lack the courage to hunt face-to-face

B. Modern hunters should use more advanced weapons

C. Modern hunters like to hunt rabbits instead of tigers

D. Modern hunters should put their safety first

Dear Peter,

I’m writing to ask whether you are able to do me a favor.

I want to have a pen friend, hopefully a girl in her early twenties, and with interests similar to mine. In my mind, she is someone who is interested in traveling, swimming, and playing table tennis. Besides, it would be better for her to have a pet dog as I have kept one at home for some time. With such a pen friend, I think I can share with her our traveling experiences, taking care of pets, or whatever we have in common. And I believe I will improve my English by doing so and learn more about her country.

Looking forward to hearing from you soon.

Best regards,
