那个时期，虎鲸(当时被称为“杀手”)帮助捕鲸人在每年须鲸迁徙时捕捉须鲸。
该句是复合句。when引导定语从句修饰time；在when引导的定语从句中，主语是the killer whales，谓语动词是helped；help后接动词原形catch作宾补；that引导的定语从句修饰the baleen whales。2．On the afternoon I arrived at the station，as I was sorting out my accommodation，I heard a loud noise coming from the bay.(P20)
在我到达捕鲸站的那个下午，在整理床铺的时候，听到从海湾那边传来一声巨响。
该句是复合句。介词短语on the afternoon 作时间状语，且后接定语从句I arrived at the station；as 引导了时间状语从句，主句中谓语动词hear后接宾语a loud noise和作宾补的现在分词短语coming from the bay。3．We ran down to the shore in time to see an enormous animal opposite us throwing itself out of the water and then crashing down again.(P20)
我们及时赶到岸边，看到在我们对面的一个庞大的动物猛力跃出水面，然后又坠落到水里。
本句中，不定式to see... 作结果状语，而see后又接了两个并列的现在分词短语throwing...和crashing...作宾补。4．I had already heard that George didn't like being kept waiting，so even though I didn't have the right clothes on, I grabbed my boots and raced after him.(P20)
我早就听说乔治不喜欢被留守，所以尽管我还没来得及把衣服穿好，也不得不抓起我的靴子跟着他跑出去。
(1)该句是一个并列复合句，so连接两个并列的句子，后一分句是一主从复合句。
(2)even though/if“即使；纵然；尽管”是从属连词，连接让步状语从句。Even if I have to walk all the way，I'll get there.
即使我得一路走着去，我也要走到那里。
Even though it was raining，we had to go out.
尽管那时正下着雨，我们还是得外出。5．A few minutes later，there was no Tom，so George started beating the water with his oar and there was Tom，circling back to the boat，leading us to the hunt again.(P20)
几分钟之后，汤姆不见了，于是乔治开始用桨拍打水面。汤姆出现了，转回到船边，又领着我们前往捕猎处。
该句是复合句。在so引导的结果状语从句中，由and连接了两个并列的句子，在and后的句子中又含有两个现在分词短语circling...和leading...作状语。6．It took over half an hour to get the boat back to James，and when we approached him，I saw James being held up in the water by Old Tom.(P21)
我们花了半个多小时才使船回到詹姆斯身边，当我们靠近他时，我发现他在水里正被老汤姆举起。
It took over...Old Tom.是个复合句，and 连接了两个并列的句子；第一个句子it作形式主语，真正的主语是不定式短语to get the boat back to James；在第二个句子中含有when引导的时间状语从句。(1)这是一个It takes (sb.) some time/sth.to do sth.的固定句式，take意为“花费、需要”，take前也可用具体名词作主语。
It takes Tom three hours to do his homework every day.
汤姆每天要用3个小时的时间做作业。 拓展：
It takes sb. ...to do sth.
做某事需要花费某人(的时间、精力等)
It costs sb.some money to do sth.
做某事需花费某人多少钱
sb.spends some money/time(in) doing sth.
某人花费时间/金钱做某事
sth.costs sb.some money
某物花费了某人多少钱sth.costs some money
某物价值多少
sb.pays some money for sth.
某人为某物付多少钱
sb.buys sth.for some money
某人花多少钱买某物 (2)being held up in the water by Old Tom 在句中作James的补足语，是see sb.being done结构。
As we drew closer，I could see a whale being attacked by a pack of about six other killers.
当我们接近时，我看见一头鲸鱼正被六头虎鲸围攻。课后双基训练 (学生用书P45)

—You can take ________you think is best to get along with you.
A．Whom; whomever

A．interviewed B．leaped
C．witnessed D．harnessed
答案与解析：C　句意：那位警察，曾经多次亲临险境，最终在执行任务时为事业献出了生命。witness“目睹，见证”。interview“面试；采访”；leap“跳，跳过”；harness“治理，控制”。由句意可知正确答案为C项。4．The new tourist hotel will have ________for more than one thousand people.

答案与解析：D　句意：虽然我比马莉从家动身晚，但是我比她提前到达晚会。in front of 指位置上在前；prior to 指时间、顺序在前；preceding为形容词，在前的，先前的；ahead of (时间性的)在……之前。6．This is a difficult problem，________ it is very interesting.
A．on other hand B．at the same time
C．in the meantime D．at all times
答案与解析：B　本题考查短语辨析，从题目前后的意思来分析有转折的含义，而C项意为“在……期间”，D项意为“无论何时”都不符合题意，A项有较强的干扰性，但是其正确表达形式应为on the other hand。7．During the Civil War thousands of people ________ the country.
A．fled B．escaped
C．ran away D．got away
答案与解析：A　不难看出空白处要填入表示“逃离”意义的词语，在所给选项中A项可用作及物动词，B、C、D三项后均应加上介词from才对。8．Why must you ________when we are having a heated discussion about our travel plan?
A．drag him behind B．drag this subject in
C．drag him D．drag on
答案与解析：B　本题是一个理解句子和词组意义的题，几个选项似乎都可以填入句中，但仔细分析就可以看出B项最佳，即最能与句意相符。句意：当我们正热烈讨论旅行计划时，你为什么要把这个话题扯进来呢？9．Walking in the forest, he felt________ by the world.
A．abandoning B．abandoned
C．to abandon D．abandonment
答案与解析：B　很显然句意含有“他感到被抛弃”的意思，故应选择表示被动含义的过去分词。10．My little brother was obviously in some kind of trouble, but I really didn't know how to ________.
A．figure him out B．sort him out
C．help him out D．take him out
答案与解析：C　句意：我小弟弟很明显有了某种麻烦，可我却真的不知如何帮他。help sb. out“帮助某人解决困难”。figure sb. out“弄明白，看透，理解某人”；sort sb. out“妥善处理；加以分类”；take sb. out“带某人出去”故答案应为C项。Ⅳ.完形填空

C. representative D. person
答案与解析：C　作者参加英语写作竞赛，是代表全班参加的，用representative表示“代表”。
2. A. proud B. delighted
C. nervous D. surprised
答案与解析：D　由于没有想到会有这种情况，所以作者“吃惊”得说不出话。3. A. get B. be
C. lose D. fall
答案与解析：D　 fall short of是固定搭配，意思是“低于预料、预期”。
4. A. promises B. expectations
C. dreams D. words
答案与解析：B　和上一空的fall short of连在一起，表示“不辜负某人的期望”。5. A. success B. beater
C. winner D. victory
答案与解析：C　既然参加竞赛，那就希望能够在竞赛中成为“获胜者”因此用winner。
6. A. memorized B. copied
C. read D. wrote
答案与解析：A　根据常识，学习英语需要“记忆”词汇、句型结构和语法规则。7. A. grammar B. phrase
C. pattern D. term

8. A. remembered B. prepared
C. started D. completed
答案与解析：B　从语境看，作者想表达时间过得快，还没做好“准备”。9. A. besides B. except
C. except for D. as well as
答案与解析：B　上文提到“我”没准备好，而别的选手看上去都做好了准备，因此此处是指不包括我在内，所以用except。若用besides表示除了我准备好了，别人也准备好了，显然不符合语境，可排除。10. A. easy B. nervous
C. interested D. unconfident
答案与解析：A　既然说其他选手都准备好了，那么他们也应该是easy“轻松的”，而不应该是nervous“紧张的”和unconfident“没有信心的”。
11. A. problem B. idea
C. topic D. theme
答案与解析：C　根据后面引号内的句子可以判断，此空格是指这篇作文的主题topic。theme侧重指论文、演讲、文学或文艺作品中的主题，较正式，因而不符合语境，可排除。12. A. writers B. teachers

答案与解析：A　writers block是一个写作术语，意思是“写作的瓶颈”，表示作者在写作时遇到了问题。
13. A. persuaded B. told
C. encouraged D. calmed
答案与解析：D　根据前面的描述，感到紧张，和下面的“took a deep breath”，说明作者在使自己“镇定”下来。14. A. with B. towards
C. at D. for
答案与解析：D　for the topic是指“为这一主题……”，for表示目的。
15. A. another B. the other
C. other D. others
答案与解析：C　前面没有范围限制，而且是做定语，所以用other。16. A. approaching B. accessing
C. finishing D. ending
答案与解析：A　因为下文说到speed up my writing，说明the finishing time并没有结束，而是“接近，临近”。approach可表示时间、空间上的接近，而access主要表示行为上接近，因此此处应用approaching。17. A. thanks for B. due to
C. as a result D. on account
答案与解析：B　这里是说明我没有写完的原因。C项和D项不论意思对否，从语法上看都缺少介词of。thanks for不表示“由于，因为”。
18. A. of which B. which
C. whose D. that
答案与解析：C　此空考查语法知识，空格后面部分是定语从句，从句中缺少定语， 所以用whose引导。19. A. However B. As a result
C. Worse still D. Although
答案与解析：D　分析前后两句的逻辑关系可以看出，前一句表示的是让步。A项不能直接引导让步状语从句，B、C两项都不引导从句，因此只能用although。
20. A. smell B. touch
C. sense D. realize
答案与解析：C　sense指“通过感官意识到”，就是我们通常说的“感觉到”。Ⅴ.阅读理解
A
Every June，on the night before summer arrives, our children are given bowls and asked to collect pieces of nature that remind them of the coming season. They leave those bowls on the front porch (门廊) and we go for a walk. When we return we find fairies(仙女)have changed the bowls into ice creams.“When are the fairies coming？”six－year－old Anna were asking all last June with expectation. Meanwhile, Jim, nine, was getting wise to fairies and such silly things. He said he would understand it, during our walk, Mom or Dad would forget something and return home.
Jim had everything figured out. The evening arrived, beautiful and pleasant. The children collected leaves and blades of grass and pebbles. We set their bowls on the front porch and took off on our walk. But midway round the block, I said that I had forgotten my keys and needed to go back. Jim smiled a knowing smile. “Oh wait，”I added. “I found them! I don't have to go back.” As we continued on our way，Jim was beginning to get a bit puzzled.
Near our house，I warned that the fairies might not have arrived yet—and that we might need to go around a few more blocks. Jim seemed to relax. Yes，he said，they probably hadn't come.Yet when we reached the porch, the bowls were in the same place we had left them—filled with ice creams.
Anna accepted all this with complete delight. But Jim was astonished，speechless. He looked up at me, at his dad, then looked around the neighbourhood in amazement.
Jim was quiet the entire evening. I kissed Anna and him goodnight and put them into bed. But at 2 am, Jim crawled into bed next to me. “Mommy，”he whispered. “I can't sleep.You have to tell me，Mommy. How did you do it？”By the time a child is nine, you need to answer a direct question with a direct answer. So I told him I had asked a neighbour to help us. After we left on our walk, she had stolen over to our house and changed the bowls. Jim smiled and thanked me for telling him. Then he hugged me and fell asleep.1. The purpose of the activity described in the passage probably is________.
A. to see off the last spring
B. to celebrate the coming summer
C. to teach the kids to love nature
D. to give the children lovely food
答案与解析：B　细节理解题。这项家庭活动是为了庆贺夏季的到来。由短文的首句Every June, on the night before summer arrives, our children are given bowls and asked to collect pieces of nature that remind them of the coming season.得出。2. Who believed in the fairies?
A. The writer. B. Anna.
C. Jim. D. The neighbour.
答案与解析：B　归纳题。九岁的儿子已经不再相信仙女之类的事了，只有六岁的女儿安娜还殷切地盼望着仙女的到来。由第二段和倒数第三段Anna accepted all this with complete delight.归纳得出。3. Why did Jim smile a knowing smile when his mother said she had forgotten her keys and needed to go back?
A. He thought his mother found an excuse to go back home to change the bowls into ice creams.
B．He laughed at his mother for her carelessness.
C．He believed his mother was making a joke with them.
D．He was happy to see her mother in trouble.
答案与解析：A　推测题。母亲找借口要回家，吉姆会心地一笑，因为他不相信会有仙女，都是父母悄悄回家做的。4. Jim was surprised when he came back home seeing the ice creams because________.
A. he had to believe there could be fairies
B. he didn't know why his sister was stupid enough to believe all this
C．he thought his parents must have cheated them
D．he had thought the bowls couldn't have been changed as his parents hadn't had a chance to play the trick
答案与解析：D　推测题。这次吉姆的父母没有机会回家。B
What do you know about the sea? We know that it looks very pretty when the sun is shining on it. We also know that it can be very rough when there is a strong wind. What other things do we know about it?The first thing to remember is that the sea is very big. When you look at the map of the world you will find there is more water than land. The sea covers three quarters of the world.
The sea is also very deep in some places. It is not deep everywhere. Some parts of the sea are very shallow. But in some places the depth of the sea is very great. There is one spot，near Japan, where the sea is nearly 11 kilometers deep! The highest mountain in the world is about 9 kilometers high. If that mountain were put into the sea at that place，there would be 2 kilometers of water above it! What a deep place!If you have swum in the sea, you know that it is salty. You can taste the salty. Rivers, which flow into the sea，carry salt from the land into the sea. Some parts of the sea are more salty than other parts. There is one sea, called the Dead Sea, which is very salty. It is so salty that swimmers cannot sink! Fish cannot live in the Dead Sea!In most parts of the sea，there are plenty of fishes and plants. Some live near the top of the sea，and others live deep down. There are also millions of tiny living things that float in the sea. These floating things are so small that it is hard to see them. Many fish live by eating these.
The sea can be very cold. Divers, who go deep down in the sea, know this. On the top the water may be warm. When the diver goes downwards, the sea becomes colder and colder. Another thing happens. When the diver goes deeper，the water above presses down on him. It squeezes(压榨) him.Then the diver has to wear clothes made of metal. But he cannot go very deep. Some people who wanted to go very deep used a very strong diving ship! They went down to the deepest part of the sea in it. They went down to a depth of eleven kilometers!5. When does the sea look beautiful?
A. When it is calm.
B. When the weather is fine.
C. When there is a strong wind.
D. When there is a storm.
答案与解析：B　从第一段的“We know that it looks very pretty when the sun is shining on it.”看出。“The weather is fine.”和“The sun is shining.”是相同的。6. Why does the author cite(引用) the sea somewhere near Japan?
A．To show that the sea in some place is very deep.
B．To show that the sea in some place is very rough.
C. To show that its depth is 9 kilometers greater than the height of the highest mountain.
D．To show that its depth is 11 kilometers greater than the height of the highest mountain.答案与解析：A　从第三段的“But in some places the depth of the sea is very great.”“What a deep place！”看出是强调海洋的深度。7. Which of the following statements about the Dead Sea is NOT true?
A. There are plenty of fishes in it.
B. It is a safe place for swimmers.
C. It is extremely salty.
D. No fish can be found in it.
答案与解析：A　从第四段的“Fish cannot live in the Dead Sea！”看出the Dead Sea里有大量的鱼是错误的。8．Why can't people go very deep in the sea?
A. Because the deepest part of the sea is very cold.
B. Because the deepest part of the sea is very rough.
C. Because the pressure of water at great depths is unendurable(无法忍受的)．
D. Because the deepest part of sea is very salty.答案与解析：C　在最后一段的“When the diver goes deeper，the water above presses down on him. It squeezes him.Then the diver has to wear clothes made of metal.”中，press(挤压)和squeeze(压榨)与题干中的pressure of water和unendurable吻合起来。C
“The noise made by boats of whale watching tourists may be causing communication problems for the animals, ”British researchers said last week.Whale－watching is a popular tourist activity in places where groups of killer whales(虎鲸) live. Every day，dozens of boats filled with tourists go to watch the beautiful animals. Unfortunately, the engines of the boats make a lot of noise，and that may be causing problems for the whales，according to a report in the US science magazine Nature.The whales travel in groups, and communicate with each other through sonic(声波的) calls that some scientists refer to as singing. The sounds of the boat engines may be creating too much background noise for the whales to be able to hear each other.
The researchers listened to recordings of whale calls made between 15 and 25 years ago, before whale watching became popular. These were compared to more recent recordings.They found that the animals have started to sing for longer than they used to, like a person shouting to a friend across a noisy room.
It is believed that the whales are trying to communicate hunting or breeding(繁殖) information. Scientists said that，if this is prevented，the future of the world's whale population could be in danger.“Animals become slow in mind and repeat themselves in noisy areas，” said Volker Deecke, a Canadian biologist. “They have to say things twice or three times in order to be understood.”
The killer whales studied were living off the coast of northwestern America. The number of killer whales in this area has been falling for several years, but scientists are not sure why.9. The passage mainly tells us________.
A．the problems of whale－watching
B. how killer whales communicate with each other
C. the reduced population of killer whales caused by whale－watching
D. hearing problems of the killer whales caused by whale－watching答案与解析：D　主旨归纳题。概括文章第一段可得出答案。观鲸船的噪音给虎鲸的信息交流造成了麻烦。A项所涉范围过大；B项仅仅是文章的细节；C项与原文信息不符，因为文章最后说明虎鲸数量下降的原因不明。10. Now in a noisy background，the killer whales have to________.
A.sing in a louder voice
B.sing longer
C. travel in smaller groups
D. get nearer to each other
答案与解析：B　细节理解题。文章第五段说明，因为受噪音干扰，现在虎鲸“唱”的时间比原来长。11. Scientists believe that killer whales sing to________.
A. warn each other of dangers
B. keep in the same group
C. send useful information
D. enjoy themselves
答案与解析：C　细节理解题。文章倒数第三段有说明，虎鲸的“唱歌”是为了交流捕食或繁殖信息。12. From the passage, we can feel that the author is________.
A. angry B. hopeful
C. worried D. disappointed
答案与解析：C　推理判断题。文章介绍观鲸船的噪音给虎鲸的交流造成了困难，从文章最后的叙述看，虎鲸数量在下降，而科学家也不明白其中原因，因此显然作者对虎鲸的生存状况感到“担忧”。
