B組

1.(07湖南24)
The biggest problem for most plants，which ______ just get up and run away when threatened，is that animals like to eat them.

答案 B

解析 句意為：對于絕大多數(shù)受到威脅時不能起來就逃跑的植物來說，最大的問題是動物喜歡吃它們。Sahan’t表將來;needn’t不必，mustn’t禁止，都不正確。

2.(07陜西14)
I told your friend how to get to the hotel，but perhaps I ______ have driven her there.

答案 D

解析 本題考查情態(tài)動詞。could have done（過去）可能做過；本能夠做……；must have done（過去）肯定做過；might have done（過去）可能做過；should have done本應(yīng)該做（而事實上沒做）。由句意“我告訴你朋友該怎么去旅館，但或許我應(yīng)該開車送她去那兒?！笨芍獞?yīng)選D項。

3.(07四川24)
—What does the sign over there read?

—You ______ do anything except to be with them and be yourself.
have to to

答案 A

解析 don’t have to不必；oughtn’t to不應(yīng)當(dāng)；mustn’t禁止，不允許；can’t不可能。答語句意為：“除了與父母呆在一起和做你自己以外，你不必做任何事情。因此A項符合題意。

5.(07浙江15)
—My cat’s really fat.
—You ______ have given her so much food.
n’t n't

答案 C

解析 考查情態(tài)動詞。句意為：——我的貓真胖。——你本不應(yīng)該給她那么多食物。shouldn’t have done sth本不應(yīng)該做某事（暗含做了）。

6.(07福建25)
My MP4 player isn’t in my bag.Where ______ I have put it?

答案 A

解析 考查情態(tài)動詞。由句意“我的MP4不在我包里。我可能把它放哪兒了？”可知應(yīng)選A。can have done過去可能做過而must have done“過去肯定做過”，只能用于肯定陳述句；should have done本應(yīng)該做過（而事實上沒做）；would have done只能用于虛擬語氣。

7.(07江蘇22)
—She looks very happy.She ______ have passed the exam.
—I guess so.It’s not difficult after all.

答案 C

解析 must have passed the exam肯定是通過考試了，由前句中的“happy”和下句中的“not difficult after all”
可以推知。

8.(07山東32)
They ______ two free tickets to Canada，otherwise they’d never have been able to afford to go.
got ? got

答案 B

解析 “otherwise they’d never have been able...”這一句用了與過去事實相反的虛擬語氣；而“他們弄到了兩張去加拿大的免費票”卻是事實，故用一般過去時。

9.(06湖北31)

A.Would you be B.Should you be ?C.Could you be D.Might you be

答案 B

解析 句意為：如果你被炒了，你的醫(yī)療保險和其他利益并不會立即取消。與將來事實相反的假設(shè)，從句用答案B項。

10.(06山東30)
— May I smoke here?
— If you ______，choose a seat in the smoking section.

答案 D

解析 由本題語境可知，空白處應(yīng)表示“非得……”之意，故須用must。

11.(06江西24)
The weather turned out to be fine yesterday.I ______ the trouble to carry my umbrella with me.
have taken ? have taken
have taken ? have taken

答案 C

解析 句意為:昨天天氣不錯，我本沒有必要不怕費事帶把傘。could have done表示“本能夠做而未做”；should have done表示“本應(yīng)該做而未做”；mustn’t表示“禁止，不許”；needn’t have done表示“本不必做而做了”。take the trouble to do sth.表示“不怕費事或困難盡力做某事”。

12.(06江蘇21)
— I think I’ll give Bob a ring.
— You ______.You haven’t been in touch with him for ages.
to

答案 D

解析 本題考查情態(tài)動詞的基本用法。will用于第二人稱常用來表示命令、指示，意為“務(wù)必，必須”；may表示“可能，也許”，常用于請求許可；have to表示“不得不”；should可用于表示主觀看法、建議、勸說，意為“應(yīng)當(dāng)，應(yīng)該”。在此句中，答話者表示同意對方的想法。答語句意為：你應(yīng)該（打個電話），你好長時間沒與他聯(lián)系了。故D項符合情景要求。

13.(06廣東22)
— Must he come to sign this paper himself?
— Yes，he ______.

解析 表示要求時，肯定回答用must， 否定用needn’t。

14.(06四川32)

15.(06陜西19)
As you worked late yesterday，you ______ have come this morning.

答案 D

解析 句意為：既然你昨天工作得那么晚，今早上你就沒必要來了。從意思上顯示選擇項表示“沒必要……”。

16.(05湖北33)
If I ______ plan to do anything I wanted to，I’d like to go to Tibet and travel through as much of it as possible.
to

答案 B

解析 句意為：如果我能計劃做任何想做的事，我想去西藏盡可能地游覽一番。觀察一下句中的時態(tài)，因為都是過去時，句意表示與現(xiàn)在事實相反的虛擬語氣，因此此處應(yīng)用情態(tài)動詞的過去

時，表示的意思是“假如我們現(xiàn)在能夠……”，could表示不存在的可能性。

17.(05重慶33)
I was on the highway when this car went past followed by a police car.They ______ at least 150 kilometers an hour.
have been doing have been doing?
have done ? have done

答案 B

解析 must have done用于肯定句中，表示對過去事情的推測，意為“想必是，一定是”。否定句、疑問句中對過去情況的推測，要用can/could have done的形式。

18.(05山東34)
He paid for a seat，however，he ______ have entered free.

答案 A

解析 paid暗示時間上指的是過去，could have done用于肯定句中表示本可以做而未做的事情；肯定句中不用need have done; must have done與語境不吻合。

19.(05江西22)
—Tom is never late for work.Why is he absent today?
—Something ______ to him.
happen have happened
have happened have happened

答案 D

解析 本題考查情態(tài)動詞的用法。must have done的意思是“一定發(fā)生了某事”。由對話所提供的情景可知：湯姆從不遲到，所以他“一定有事”。因此D項正確。

20.(05安徽26)
Helen ______ go on the trip with us，but she isn’t quite sure yet.

答案 C

解析 此題考查情態(tài)動詞的用法。may表示一種可能性。如果沒有具體的語境的話，B、D兩項也可以選，但是意思就不同了。

21.(05江蘇31)
—The woman biologist stayed in Africa studying wild animals for 13 years before she returned.
—Oh，dear!She ______ a lot of difficulties!
go through go through
to have gone through have gone through

答案 D

解析 考查“情態(tài)動詞+have done”。從語境分析，表示某人一定干過某事，而且是對過去情況肯定的推測，故應(yīng)用must have done。C項相當(dāng)于should have done表示對對方的責(zé)備，意思是“應(yīng)該做而未做”，在此不符合題意。

22.(05江蘇33)
—Don’t you think it necessary that he ______ to Miami but to New York?
—I agree，but the problem is he has refused to.
not be sent;that ? be sent;that
not be sent;what not send;what

解析 not be sent是虛擬語氣，相當(dāng)于should not be sent。

23.(04重慶24)
“The interest ______ be divided into five parts，according to the agreement made by both sides，”declared the judge.

答案 D

解析 考查shall的習(xí)慣用法。shall與第二、三人稱名詞連用，表示義務(wù)，責(zé)任，決心，許諾，它可以用于條文中；should/must用于口語中。

24.(04重慶29)

25.(04全國Ⅰ29)
—Isn’t that Ann’s husband over there?
—No，it ______ be him.I am sure he doesn’t wear glasses.
’t n’t not

答案 A

解析 考查否定的推斷。can’t不可能；must not不許；won’t將不會；may not可能不。根據(jù)“I’m sure he doesn’t wear glasses（我確信他不戴眼鏡）”可知，說話者的態(tài)度是：不可

能是他。

26.(04上海28)

A. must

答案 A
