Ⅲ. 阅读理解（共两节，满分40分）
第一节 （共15小题；每小题2分，满分30分）
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。
A
In October on the east coast of Australia migrating（迁徙）humpback whales（座头鲸）pass very close to the shore. With the help of Max Egan, we went to film them near Byron Bay. It was extremely exciting to spot the little puffs（水柱）of spray on the horizon. When migrating, the whales can be travelling at the speed of about 12 km/h and can dive under anywhere between five and forty minutes, but with many years of experience Max usually guided our boat to exactly the right place to provide us with amazing sighting. As the whales break the surface like submarines（潜水艇），the water spills off their broad dark backs and huge tails. Then, with a powerful down stroke, they dive back into the depths of the sea, leaving just a smooth glassy patch of water or “footprint” on the surface to show where they had been.
One day we had travelled up and down the shore and far out to the sea in search of whales, but the horizon was deserted. There was no report of whales in the area so we decided to test out Max's new, highly sensitive hydrophone（水中听音器）and the result was astonishing. As soon as the hydrophone was in the water, we found ourselves listening to the most beautiful voices. What may have seemed like a vast empty ocean was filled with the singing of whales.
It is the males which sing, as they migrate between feeding and breeding（养育）grounds. No one knows for sure what the purpose of these songs is, whether they are love songs to the females or warnings to other males to stay away.
It was thought that each group of humpbacks had their own song which remained regular but recent findings suggest that the whales appreciate a memorable tune（曲调）and quickly adopt any new songs they hear.
36. Which finding about whales is beyond the writer's expectation
A. The little puffs.
B. The songs of whales.
C. The travelling speed of whales.
D. The depth of the whale's dive.
37. The writer's main purpose of looking for whales is __________.
A. carrying out research on whales
B. studying the beautiful songs of whales
C. making films about whales
D. hunting whales for research
38. What's the WRONG opinion about whales according to the passage
A. Each group of humpbacks had the song of their own.
B. Whales can't sing to each other.
C. Whales aren't easy to find.
D. Whales can't dive in the sea as long as forty minutes.
B
There's no end of dangerous sports to try out in Southern Africa—bungee jumping, skydiving, water rafting. But for a new rush, how about swimming face to face with a killer shark（鲨鱼）？
The public seems interested in seeking excitement in this activity. Cape Town's aquarium has been filled with divers who want to swim with the sharks since it opened its tanks to paying visitors last month. Around 70 tourists aged between 12 and 40 have paid 275 rand（＄55） each to spend up to an hour with Maxine, Dee and Floyd.
And conservationists（自然环境保护论者）say the project should help change the damage done to the shark's image by the popular movie Jaws.
“People will always pay money to be a bit daring, ”said Paul Loetter, an aquarium diver. “Most people think every shark is dangerous, but they've got the wrong idea. ”
Each visitor can swim with the sharks and other fish that share their tank, guarded by aquarium divers armed only with a stick to keep off any over-friendly sharks.
“This is part of a communicational and educational programme to show sharks are not as bad as everyone makes out, ” said Tony McGyre, operational manager of the aquarium.
Len Compagno, head of the South African shark research centre, agreed. “It's no joke to play around with a big dog. In the same way, a three-metre-long shark could put a few holes in you, ” he said.
39. We may infer that in the movie Jaws __________.
A. sharks are hunted everywhere
B. sharks kill other sea animals
C. sharks are disappearing in the sea
D. sharks are man eaters
40. What Len Compagno said really means that __________.
A. you had better not get close to sharks
B. you needn't be too serious about sharks
C. sharks are more dangerous than big dogs
D. sharks are as friendly to people as dogs
41. The writer's purpose in writing the passage is to tell us that __________ .
A. sharks are not as bad as everyone makes out
B. people will always pay money to be a bit daring
C. there's no end of dangerous sports in Southern Africa
D. the public seems interested in seeking excitement in swimming with a killer shark
42. We can learn that Maxine, Dee and Floyd are __________.
A. workers in the aquarium
B. the aquarium's three sharks
C. conservationists
D. divers in the aquarium
C
Dolphins are not fish, but warm-blooded animals. They live in groups, and speak to each other in their own language. In this way they are like other animals, such as bees and birds. But dolphins are very different from almost all land animals. Their brains are nearly the same size as our own, and they live a long time—at least twenty or thirty years.
Like some animals, dolphins use sounds to help them find their way around. They also make these sounds to talk to each other and to help them find food. We now know they do not use their ears to receive these sounds, but the lower part of the mouth, called the jaw.
Strangely, dolphins seem to like man, and for thousands of years there have been stories about the dolphin and its friendship with people. There is a story about sailors in the 19th century. In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack. From 1871 to 1903, Jack met every boat in the area and showed it the way. Then in 1903 a passenger on a boat called The Penguin shot and wounded Jack. He recovered and for nine years more continued to guide all ships through the area—except for The Penguin.
Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them.
43. Dolphins are different from many other animals in that they __________.
A. live in groups
B. have large brains
C. are warm-blooded
D. have their own language
44. Which of the following does the dolphin use to help it find its way around
A. Its nose. B. Its ears.
C. Its mouth. D. Its eyes.
45. Why did the sailors off the coast of New Zealand look for Jack
A. He was lonely and liked to be with people.
B. They enjoyed playing with him.
C. He was seriously wounded.
D. They wanted his help.
46. By telling the story of Jack the writer wanted to show that __________.
A. dolphins are friendly and clever
B. people are cruel to animals
C. Jack is different from other dolphins
D. dolphins should be protected by law
D
Do's and Don'ts in Whale（鲸）Watching
The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnstone Strait, where killer whales are found on a daily basis each summer. It is strongly recommended that vessel（船只）operators follow these guidelines for all kinds of whales.
●Approach whales from the side, not from the front or the back.
●Approach no closer than 100 metres, then stop the boat but keep the engine on.
●Keep noise levels down—no horns, whistles or racing of engines.
●Start your boat only after the whales are more than 100 metres from your vessel.
●Leave the area slowly, gradually moving faster when you are more than 300 metres from the whales.
●Approach and leave slowly, avoiding sudden changes in speed or direction.
●Avoid disturbing groups of resting whales.
●Keep at low speeds and remain in the same direction if travelling side by side with whales.
●When whales are travelling close to shore, avoid crowding them near the shore or coming between the whales and the shore.
●Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales.
●If there is more than one vessel at the same observation spot, be sure to avoid any boat position that would result in surrounding the whales.
●Work together by communicating with other vessels, and make sure that all operators are aware of the whale watching guidelines.
47. For whom is this text written

Dear Li Hua,
I'm very glad to receive your letter two weeks before, and I have been thinking about question you asked me. In my opinion, you should go back after you finish your studies abroad. For one reason, what you are studying is badly need nowadays in our country. It will be quite easily for you to find a good job. In fact, I know a few company here in our city hope to hire people like you. For another reason, I think it will be much convenient for you to look after your parents as they were getting old. Therefore, this is only my point of view. It is up for you to make a right choice.
Yours,
Wei Fang

答案与解析
1. B 句意：很多生活方式对身体健康有如此大的危害，以至于实际上它们加快体质变弱。do harm to ...“对……有害”；第二个空为特指的用法，即特指体质变弱，故用定冠词the。
2. A 句意：地震发生之后，当地政府所做的第一件事就是为无家可归的家庭提供住处。accommodation“住处，膳宿”，符合句意。
3. A 由“I'm not using it anyhow.”可知，此处应用go ahead表示允许对方做某事。
4. D away, in, out等表示方向的副词作状语位于句首时，句子要使用部分倒装语序。此处强调的是逃跑的动作，故选D项。
5. C 句意：在不久的将来，中国将增加较小面积房屋的供应量，旨在帮助低收入家庭购买自己的住房。句子的主语China与aim之间是主动关系，故用v. -ing作状语，根据时间状语in the near future可知选C项。
6. B 句意：船长催促这项任务要在天黑前完成。urge后面的宾语从句通常用虚拟语气，即谓语用“should +动词原形”形式，should可以省略。
7. B 句意：有人发现汤姆丢失的汽车被丢弃在高速公路旁的树林里。abandon“丢弃，遗弃”，符合句意。
8. A 句意：接近市中心时，我们看到了一座大约10米高的石雕。句子的主语we与approach之间是主动关系，故用v.-ing形式作状语，表示正在进行的或主动的动作。
9. A 句意：这对夫妇已经决定推迟买车，直到他们的经济状况变得更好。hold off “拖延，推迟”，符合句意。
10. D 句意：无论什么时候她听到有人遇到麻烦，她总是去帮助他们脱离困境。help out “帮助……脱离困境”，符合句意。
11. C 句子的主语Australia与separate之间是被动关系，且separate发生在has之前，故用现在分词的完成被动式作状语。
12. A 句意：起居室既干净又整洁，做饭的餐桌已经摆好了。with复合结构的构成是“with＋宾语＋宾语补足语”，由于a dining table与lay之间是逻辑上的被动关系，所以空格处用过去分词。
13. D 空格后面不是句子，故排除C项；aware后应接介词of，故排除A项；表示“清醒，充分认识到”时，aware的修饰语应使用well，不用very，故排除B项。
14. D 第一个空用reading作伴随状语；第二个空one与profit之间是主动关系，故用v.-ing作后置定语。
15. D sharply “急剧地，急速地”, bend sharply“急转弯”，符合句意。
16. B 从下文可以得知佩里此刻想使鲨鱼游到海里，以便涉水到岸上去。
17. A 他必须在鲨鱼看到他之前游上岸。“before＋从句”表示时间。
18. B 根据上句他看到鲨鱼在翻滚玩耍可知，鲨鱼现在已不再饥饿。此题考查名词辨析，hunger“饥饿”。
19. D 此题考查动词辨析。根据常识，鲨鱼能闻到血腥味，因此应填smell。
20. C 佩里将刀子割进肉里以便流出一些血，排除A、B两项。meat为动物的肉的总称，flesh可以指人的肉体，故选C项。
21. A 血流得足够多时，佩里止血。
22. A 佩里把染了血的衬衫放到水里，用绳子拉着。pull“拉”;wrap“包裹”;connect“连接”;catch“抓住”。
23. B 用racing表示鲨鱼闻到血腥味后行动很快。根据下一句中的“raced”也可知，应选B项。
24. D 佩里领着鲨鱼游离海岸。lead sb./sth. away from...“领着某人／某物离开……”。
25. B 他自己扔下衬衫，返回海边上岸。
26. D 佩里游了一半，“这时”转过身来。
27. C cut“切；割；砍”。这条鲨鱼的速度很快，它的鳍就像把水割开一样。
28. A 后面有鲨鱼，佩里当然竭力向前游。forward“向前”；backward“向后”；upward“向上”；downward“向下”。
29. B 佩里露出头来呼吸。
30. C 此处指佩里用手指撑着使自己爬上石头，而不是用脚蹬着石头。with his fingers“用手指”。
31. D 根据鱼类常识可知，鲨鱼因血腥味和追逐而变得异常兴奋。excited“兴奋的”；interested“感兴趣的”；frightened“受惊的，受恐吓的”; disappointed“失望的”。
32. C 这条鲨鱼因用力过猛而撞到了石头上。由上文可知，鲨鱼紧追佩里，佩里爬上了岸上的礁石，鲨鱼紧随其后，自然撞上了礁石。
33. B 这条鲨鱼只是受伤，所以是被其他鲨鱼活吃了。首先排除C项。alive adj.“活着的”，在此处作伴随状语，表示被吃的时候的状态是活的；lively adj.“活泼的，活跃的，栩栩如生的”；friendly adj.“友好的，亲切的”。
34. C struggle to one's feet是固定搭配，意为“挣扎着站起来”。
35. B 尽管不饿，但是鲨鱼仍在吃着。as though“好像，仿佛”；even though “即使”；as soon as “一……就……”;as long as“只要”。
36. B 根据第二段第二句“...the result was astonishing.”可知，发现鲸鱼美妙的歌声是作者的意外收获。
37. C 根据第一段第二句“...we went to film them near Byron Bay.”可知C项正确。
38. A 由最后一段可知，原先人们认为，每一群座头鲸都有自己相对固定的歌，但这次的发现证明这种观点是错误的。
39. D 推理判断题。根据文章第三段可推断鲨鱼在电影《大白鲨》中的形象是不好的。对比现在人们敢于跟它们面对面地游泳可知，在该影片中鲨鱼对人是有伤害的，故D项最佳。
40. B 推理判断题。由最后两段可知托尼与伦恩观点一致，即：鲨鱼并非人们想象的那么坏，因此不必对鲨鱼太紧张。
41. A 写作意图题。文章讲述了人们可以在水族馆里和鲨鱼一起游泳，科学家们进一步评价，鲨鱼并不像人们认为的那么糟糕，这也正是作者的写作目的。
42. B 推理判断题。第二段讲游客与鲨鱼一起游泳，由第二段最后一句“Around 70 tourists ... spend up to an hour with Maxine, Dee and Floyd.”可知“Maxine”, “Dee”与“Floyd”是鲨鱼的名字。
43. B 细节理解题。由文章第一段最后两句可知，海豚与众不同的是它们的大脑与人脑大小接近，大于几乎所有别的动物的大脑。
44. C 细节理解题。由第二段最后一句“We now know...but the lower ... called the jaw. ”可知海豚利用下颌接收帮助它们寻路的声波。
45. D 细节理解题。由第三段倒数第三句话可知Jack可以给水手们带路。
46. A 主旨大意题。由第三段第一句“Strangely..., there have been stories about the dolphin and its friendship with people.”及全文可知A项正确。
47. C 细节理解题。由第一段最后一句“It is strongly recommended that… all kinds of whales.”可知文章是针对船只驾驶员撰写的。
48. B 细节理解题。根据第五条准则可知，船只离开观看区域时，要逐渐地加速。
49. A 细节理解题。由第八条准则可知，与鲸鱼并排前行时，船只应与之保持相同的方向。
50. D 推理判断题。准则二、四、十中分别提到离鲸鱼不要少于100米，鲸鱼离开超过100米后再开船，以及离鲸鱼100到200米的距离，由此可推断离鲸鱼最近的安全距离是100米。

Dear editor,
We have to say that the pollution is now getting worse and worse. The other day my friend and I went fishing on a riverside. We found the river so dirty and the smell so terrible that we could hardly stay there. We also found lots of rubbish and dead fish floating on the water.
It is all because a lot of factories always send waste water into it and some people throw rubbish into the river. If rivers all over the country were polluted like this, all the living things in the water would be killed and harm would be done to the people close to the rivers. We expect the river will be made clean again soon, and measures should be taken to stop polluting our surroundings.
Yours sincerely,
Wang Ning
