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.

The professor gave orders that the test ____before 5:30.
A．be finished B．will finish C．will be finished D．shall finish
【答案】A

考点：考查虚拟语气的用法。
点评：本题难度适中。虚拟语气是高中阶段的重难点之一，虚拟语气的情况复杂，形式多样，需要考生牢记它们的不同的用法，再根据不同的语境分析句子应该用哪种情况的虚拟。这里是order当“命令”讲时，它的宾语及同位语从句都是用should+动词原形。这里考生容易误选C。
即学即练：If he ________ that he _________ to work there, everything would be OK now.
A. insisted; be sent B. insisted; was sent
C. had insisted; be sent D. had insisted; was sent
解析：C。句意：考查虚拟语气在insist从句中的用法。若insist表示“坚持要求做某事”,从句中应用should+动词原形, should可省略；若insist表示“坚持说，坚持认为”,则从句需根据句意选择合适的时态。句意为：如果他坚持要求被派往那儿的话，现在一切都好了。事实上并非如此。故选C。
In our town, wood can ___________ a fire.
A．be used to make B．be used to making
C．use to make D．used to making
【答案】A
【详解】考查固定短语和被动语态。句意：在我们镇上，木头可以用于生火。木头是被用来生火，sth. be used to do意为“某物被用来做某事”，to后跟的是动词不定式，而be used to doing意为“习惯于做某事”，CD两项是错误短语，因此空格处是be used to make，故选A。

A．needn’t have been finished
B．shouldn’t have finished
C．could have been finished
D．must have finished
【答案】C
【详解】考查情态动词和虚拟语气。句意：这个项目本来是可以在上个月完成，但是不幸的是，因为财政问题，它不得不被延期。根据“but unfortunately it had to be prolonged because of the financial problem”及句意可知，此处表示“上个月本可以完成，但没完成”。主语The project与finish是动宾关系，故用被动语态，故用could have been finished表示“本可以被完成，却没有被完成”，故选C。

C．evaluated D．encouraged
【答案】C

The accident which left 15 people on board dead ________ if both the angry female passenger and the bus driver had kept calm.
A．should have avoided B．should be avoided
C．could have avoided D．could have been avoided
【答案】D

A．Can B．Should C．Must D．Would情态动词被动
要点点睛：
情态动词的被动语态：情态动词+be done
虚拟语气：require引导宾语从句，谓语动词用(should )+v.
注意在表示建议、要求、命令以及坚持等词后的宾语从句中要用should+动词的虚拟语气，其中should可以省略。
情态动词+ have done结构：
对过去进行推测
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.
Another worker wouldn't have acted like that.

情态动词是近几年高考的热点，它们的用法非常多，需要考生平时多做练习加以巩固。这里需要区分它们的用法及意义。

(2)表示请求或许可 “可以” 例如：Can I help you 要我帮忙吗
(3)表示猜测 “可能” 例如：Where can she go now 她可能到哪里去了呢
2. may 的用法：
(1)表示请求或允许 “可以”“准许” 例如：May I go home, please
(2)表示可能性 “可能”也许” 例如：I think it may rain this afternoon.
注：might为may的过去式，但也可以代替may，语气较为婉转客气或更加不肯定。

注意：①must开头的疑问句，其否定回答通常用don’t have to 或needn’t，而不用mustn’t。
例如：—Must I finish my homework first
—No, you don’t have to/ needn’t.
②can 和 must在表推测时，can一般否定句中，而must 常用于肯定句中。
