本句中should 作为情态动词,可以用来表示意外、惊喜或者在说话人看来是不可思议的,常常译为"竟会"、"居然",住的这么近的邻居居然不认识。表示意外,所以答案选C。

14.— Mum, little Ray broke his toys again!

—It doesn't matter. You see, accidents _____happen.

A.shall B.should C.must D.will

We will do our best to save the child. 我们会尽力抢救这个孩子。

I told her to stop crying, but she just wouldn’t listen. 我叫她别哭,可她就是不愿听。

注:表示请求、建议或征求对方意见时,用Would y ou…? 比用Will you…?更婉转。如:

C.can have done D.might have done

【答案】D

【解析】

【详解】

真的做了吗”,表示怀疑;need have done需要做某事,实际上却未做(表示虚拟语气);must have done一定做了某事(表示对过去发生的事情的肯定推测);might have done表示对发生过的事情的推测,意思是“可能已经”或“也许已经”,用于肯定句中。故D正确。【点睛】

本题是高考必考考点,一定要牢记句型意思。must have done过去肯定做了某事。should have done本应该做而实际未做。can’t have done过去不可能做了某事;shouldn’t have done

本不应该做而实际做了。need have done本有必要做某事而没做;needn’t have done本没有必要做某事;注意没有mustn’t have done的形式。

【点睛】

情态动词+ have done结构:

1.“must + have + 过去分词”表示对过去发生的事情或状态进行推测,语气比较坚定,通常只用于肯定句。如:It must have rained last night, for the ground is wet.

2.“can / could + have + 过去分词”表示对过去某种情况的怀疑或不确定。can和could一般用于否定句和疑问句,could的语气较can弱。如:He can't have finished the work so soon.

3.“may / might + have + 过去分词”表示对已发生的动作或存在的状态进行不肯定的推

测,might的语气比may弱一点.这种结构主要用于肯定句和否定句,疑问句改用can或could,如:They may not have known it beforehand.

4.“need + have + 过去分词”表示过去做了不必做或不需要做的事情,或过去做某事纯属多余,如:I needn't have bought so much wine—only five people came.

5.“should / ought to + have + 过去分词”表示过去本该做某事但没做,其否定式表示过去不该做某事但做了,这种句式含有不满或责备之意,ought to的语气比should强一些。如:You ought to / should have studied harder.你本应该更努力学习的。(但没有)

He oughtn't to / shouldn't have done that.他本来就不该做那件事。(可是做了)

6.“would + have + 过去分词”表示对过去的某种情况进行猜测,或本来要做某事却因某种原因未做成,通常用来说明某一情况,但不像用should或ought to那样含有责备之意。如:I guess the poet would have been about twenty when she wrote her first poem.

【答案】D

【解析】

【分析】

【详解】

考查情态动词+have done。句意:——你昨天参加实验项目的会议了吗?——是的,但我想我(本来)不需要,因为我的主管在那里。Think/suppose等宾语从句中如果有否定词时,要把从句的否定词not前移,即“否定前移”。所以not是从句中的否定词。“need have done”意为“本来有必要做而未做”;“needn’t have done”指过去本来没必要做而做了。根据上一句时间状语“yesterday”可知本句指的是过去发生的事。结合第二句“because my d irector was there(我的主管)在”可推断出,我本来不必要去。故选D。

25.Look! There are so many mistakes in your composition. You ________ have fixed full attention on it.

A.can B.should

C.need D.might

【答案】B

A.Should B.Were C.Would D.Had

【答案】A

【解析】

【分析】

【详解】

考查虚拟语气。句意:我们将对我们的计划做最后决定。如果你改变主意,请尽快通知我们。根据语境,此处用虚拟语气,表示与将来相反,从句用should+动词原形,省略if,should提前,陈述句是:If you should change your mind……。故选A。

【点睛】

虚拟语气中的倒装

当虚拟条件句中含有 were,had,should时,可以将if省略,然后将 were,had,should,移至句首:

1)If he should fail, he would kill himself.

→Should he fail, he would kill himself.

万一失败,他就会自杀。

2)If I were you, I would do it at once.

→Were I you, I would do it at once.

假若我是你,我就会马上做。

要是我能做此事,我一定会做。

3)If he had seen you yesterday, he would have asked you about it.

→Had he seen you yesterday, he would have asked you about it.

他昨天要是看到了你,他就会问你这事了。

该小题属于上述的第一种情况。should作为情态动词,有一种特殊的用法:在虚拟条件状语从句中表示与将来事实相反的虚拟语气,可以把should放在句首,即主语前,从而省略从属连词if。原来的表述为:If you should change your mind。故选A。

C.have come D.had come

【答案】A

【解析】

试题分析:本句考查的是一个含蓄的虚拟条件句,句中的or相当于if they had not gone abroad.因为前面句中使用的是were,说明这个虚拟语气是与过去事实相反,所以主句中使用的是“情态动词+have done”的形式。句意:当我们在做调查的那几个月里,他们一直在国外,否则的话他们早就来帮助我们了。故A正确。

情态动词 知识讲解

情态动词 【概念引入】 1)情态动词表示说话人对所做动作的观点或态度。如:需要、可能、意愿、怀疑等。 例如:I must go now.我现在必须得走了。 2)情态动词一般没有人称和数的变化,但是个别情态动词有时态的变化。 例如:can的过去式是could。 3)情态动词不能单独作谓语,后接动词原形共同做谓语。 例如:I can swim.我会游泳。 4)常见的情态动词有:can, may, must, have to, should, would等。 5)情态动词一般不止一个意思,它的否定式是在情态动词的后面加not,一般疑问句是将情态动词提到句首。 例如:I can’t speak French.我不会说法语。 Can you speak English?你会说英语吗? 【用法讲解】 1.can的用法。 1)表能力 We can do our homework by ourselves.我们可以自己完成作业。 He can swim well.他游泳很好。 I can play football but I can’t play the piano.我会踢足球但是我不会弹钢琴。 2)表xx You can watch TV after supper.晚饭后你可以看电视。

You can’t play basketball in the street.你不能在街上打篮球。 3)表请求 Can you help me with my math?你能帮我学数学吗? Could you lend your book to me?你能把你的书借给我吗? 注意:could 是can的过去式,但是这里并不表示过去时,而是表示委婉语气。 拓展:can 和be able to的区别 (1)情态动词can只有两种时态形式,现在式can和过去式could,而be able to有多种时态形式。在一般过去时中都表示能够时,两者可以互换。 例如:Mary can play the piano.(一般现在时) xx会弹钢琴。 She could / was able to play the piano when she was five.(一般过去时)她五岁时就会弹琴。 She has been able to play it since she was five.(现在完成时) 她自从五岁起就会弹琴了。 (2)用在过去时中,could经常表示能够做某事,事实上不一定去做,而was ?were able to则表示“过去设法做成了某事”。在否定句中两者可通用。 例如:He could swim across the English Channel. But he didn’t want to do it that day.他能游过英吉利海峡,但那天他不想游。 Yesterday I was able to get home before the heavy rain. 昨天我在下大雨前赶到了家里。 4)表示“不可能……”
