考查“情态动词 +完成式 ”。句意:如果愤怒的女乘客和巴士司机保持冷静,这起导致 15 人

accident 和谓语动词 avoid 之间是被动关系,结合句意可知答案为 【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 beforeha nd.

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. “ woul +d 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. Another worker wouldn't have acted like that.

must have done 用法辨析

the

”表示对过

【解析】

试题分析:考查情态动词用法。

Shouldn t have done 本不应该做某事,实际上却做了(虚

拟语气);couldn ' t have don 不可能做某事(对过去情况的推测); needn' t have done

不需要做某事,实际上却做了(虚拟语气);句意:我的姐姐昨天下午在街上遇见了他, 所以他不可能去听了你的演讲。故 B 正确。

过去 .]

The temperature must have dropped to below zero last night, because the water is frozen all over. 昨夜的温度肯定降到零度以下,因为水都冻住了。

如果 “ must + have +过去分词 ”句型与 by now 连用,还可以表示对现在完成的动作和状态的 肯定推测,但实质上还是指所推测的过去的动作。例如:

They started early this morning; they must have arrived by now. 他们今晨很早就出发

了,现在 肯定已经到了。

中国学生的常见病句是: They...; they certainly have arrived. 病句的句义是 “他们当然已经到 达了。 ”(这不是对过去的肯定推测,而是断定动作已经完成。)

6.would 可以表达过去常常做的事,过去习惯发生的动作: Pirates would bury gold in a cave. 海盗们常常把黄金藏在山洞中。 We would take a walk along the river. 我们过去常常

沿河散步。

3. would 后接 like 、 love 、mind 等动词,表示要求、邀请、希望或询问,此时不是说过去, 而是

吗?

Would you mind coming with us? 你介意和我们一起吗? 比如

D . needn ' t have attended

事。should have done 本应该做而实际未做。
