篇1：虚拟语气课件虚拟语气课件
Ⅰ用以表示虚拟条件的虚拟语气
1. 用if条件从句表示的虚拟条件，是虚拟条件最普通的方式。
① 虚拟现在时表示与现在事实相反的假设，其if 从句的谓语形式用动词的过去式(be 一般用were)，主句用would/ should/ could/ might +动词原形，例如：If I were in your position I would marry her.
② 虚拟过去时是表示与过去事实相反的假设，if 从句的谓语形式用过去完成时即had＋过去分词，主句用would / should / could / might + have +过去分词，例如：If it had not rained so hard yesterday we could have played tennis.
③ 大多数的虚拟条件句属于上面三种情况的一种，但并不排除存在条件和后果中，一个和现在情况相反，另一个和过去情况相反，例如：If you had followed what the doctor said, you would not have been so painful now.这个句子在高中出现频率颇高。
④ 但是，如果后果用了虚拟语气，而条件却用陈述语气，这种用法是错的。
2. 除了表示虚假条件外，if从句还可以表示对将来的推测，由于是将来还没有发生的，所以谈不上是真实的还是虚假的，只能说这个事情发生的可能性有多大。一般情况下，可以用陈述语气的'if从句来表示对一个未来事实的推测，这个事实是完全可能发生的。If从句的谓语形式用一般过去式或用were to / should +动词原形，主句用would / should /could/ might +动词原形，例如：Jean doesn't want to work right away because she thinks that if she were to get a job she probably wouldn't be able to see her friends very often.
3. 有时可以把含有助动词、情态动词、be或have的虚拟条件句中的连词if 省去，而将had , should, were 等词提到主语之前，即用倒装结构,这时候，如果出现not等否定词，否定词需放在主语后面。这种结构在口语中很少使用，但频频出现在各类考试中出现，例如：If it had not rained so hard yesterday we could have played tennis.→Had it not rained so hard yesterday, we could have played tennis.
4. 大多数的虚拟条件通过上面所讲的两种方法表达，但在个别句子中也可以通过介词without和介词短语but for表达，副词otherwise等表达出来。例如：We didn't know his telephone number; otherwise we would have telephoned him.值得注意的是，包含but for的句子，谓语动词必定要用虚拟形式，但包含without等短语的句子，谓语动词未必一定要用虚拟语气。
5. 有时虚拟条件不是明确地表达出来，而在蕴含在用but引导的从句里，于是便出现了有谓语动词是虚拟语气的主句加上谓语动词是陈述语气的but从句构成的并列复合句，例如I would have hung you but the telephone was out of order.在这样的句子里，如果主句没有用虚拟语气，或者从句用了虚拟语气，都是错的。
Ⅱ用在宾语从句中的虚拟语气
1. 在表示愿望的动词wish后的宾语从句中，需用虚拟语气。（wish后的that 常省略），根据主句时态，从句谓语时态相应退后一位，例如：How she wished his family could go with him.
2. 在具有愿望、请求、建议、命令等主观意愿的动词(desire, demand, advice, insist, require, suggest, propose, order, recommend, decide …) 后的宾语从句中需用虚拟语气。谓语动词用(should) +动词原形。值得注意的是，如果宾语从句的动词是否定的，否定词not的位置应在动词之前，而不是动词之后。例如：The head nurse insisted that the patient not be move.另外，如suggest表达“暗示”，insist表示“坚持某种说法”时，后面的从句不用虚拟语气，例如：Her pale face suggests that she is ill.或He insisted that he did not kill the boy.
除此之外，上述动词也要求用虚拟式
① 在It is+上述动词的过去分词，其后所跟的主语从句中，如It is suggested that pupils wear school uniforms.
② 在上述动词相应的名词形式作主语+连系动词，其后的表语从句中，例如His suggestion was that classed be re-scheduled.
③ 在对上述动词相应的名词进行解释的同位语从句中，如：The workers raised the demand that their pay be increased to cope with the inflation.
3. would （had）rather , would sooner也用来表达主观愿望，它们之后的宾语从句中需用虚拟语气。谓语动词用过去式表示现在或将来，用过去完成式表示与过去事实相反，例如：I would rather he went right now.
Ⅲ其他形式的虚拟语气
1. it is +necessary等形容词后，that主语从句中虚拟形式使用，这类形容词包括necessary, important, essential, imperative, urgent, preferable, vital, advisable等，例如It is necessary that you listen to the teacher carefully.或者It is essential that you be able to pronounce every single word correctly.
2. 在It's (high/about) time 之后的定语从句中需用虚拟语气。谓语动词用过去式，例如It is high time that you went to school
3. 虚拟语气在as if / as though 引导的方式状语从句中的应用（谓语动词形式与wish后的宾语从句基本相同）表示与现在事实相反或对现在情况有怀疑，谓语动词用过去式。例如：He felt as if he alone were responsible for what had happened. 表示过去想象中的动作或情况，谓语动词用过去完成式。
4. 在lest 引导的状语从句中，谓语动词多用虚拟语气，(should )+ 动词原形。例如： The mad man was put in the soft-padded cell lest he injure himself.
5. 在if only 引起的感叹句中需用虚拟语气。谓语动词用过去式或过去完成式。例如： Look at the terrible situation I am in! if only I had followed your advice.
篇2：虚拟语气1.虚拟语气在条件句中的用法
(1)若表示与现在事实相反的假设，则条件从句中用过去式，主句中用过去将来式（would，should，could，might + 动词原形）；
(2)若表示某事将来实现的可能性不大，则条件从句中用should + 动词原形也可用“were to+动词原形”或用过去式动词。如：
I would certainly go if I had time．（现在）
If it should rain，we wouldn't go out.（将来
（3）若表示与过去事实相反的假设，从句中用过去完成式，主句中用过去将来完成式（should，would，could，might + have + 过去分词）。如：
If I had set off a little earlier， I would have caught the train．
She would / might have come if she hadn't been so busy．
If I hadn't taken your advice，I would have made a bad mistake．
（4）含有虚拟语气的条件状语从句中，如有had，should，were 这三个词的话，在正式或书面语言中可将if省略，再将句子的主语和谓语动词实行全部倒装或部分倒装。如：
Had they time（=If they had time），they would certainly come and help us．
Should it be fine（=If it should be fine），we would go for an outing．
Were I go（=If I were you）， I would go．
（4）若主句从句所指的时间不一致，即条件从句表示与过去事实相反，主句表示与现在事实相反；或者条件从句表示与现在事实相反，主句表真实情况，则从句中应采用与具体时间相对应的虚拟形式。如：
If it had rained last night（过去），It would be very cold today（现在）．
If I had taken your advice（过去），I should have no trouble with the work now（现在）．
2．虚拟语气在宾语从句中的用法
在动词suggest，order，demand，propose，request，command，insist等后的宾语从句中，用虚拟语气（即Should+动词原形或只用动词原形）来表示愿望、建议、命令、请求等。在动词wish /would rather后的宾语从句中，用过去式表示与现在事实不符，用过去完成式表示与过去事实不符。如：

答案与详解
1．A．条件句表示与现在事实相反的虚拟。
2．B．条件句表示与过去事实的虚拟。
3．A．条件句表示与未来事实的虚拟。
4．B．条件句表示与未来事实的相反。
5．C．条件句表示与现在事实的虚拟。
6．D．条件句表示与现在事实的虚拟。
7．B．这个句子中含有一个省略if，把助动词提前到主语they之前的虚拟条件句，该条件句表示对过去情况的假设，而主句中by the time they were finished 表明主句也应该是对过去发生的情况的假设，因而应该选（B）would have lost为正确答案。
8．（D）这道题目是一个混合虚拟语气的句子。条件句省略了if，把助词had提前到主语前面，表示对过去情况的假设，而主句中now表明了对现在情况的假设，所以应选would(should, could, might)+动词原形这种表达形式。四个选项中只有（D）是正确表达形式，故为正确答案。
9．（D）until recently，因此（D）是正确答案，而主句是隐含的对现在情况的假设，该句是一个混合虚拟条件句。
10．（B）假设的情况有时不是用一个条件句表示，而是隐含在一个由介词如but for、but that、without, 由连词but、副词otherwise 、比较级、形容词、独立主格等表示的上下文中。本句主句表示对过去情况的假设，但事实上由于英语考试而没有去成，即若不是因为英语考试，我本可以去听音乐会，所以应选But for为正确答案。
11．（C）题目中的第一句话表示的是现在真实的情况，而第二句话中所要表达的是应该做但事实上没有做的事，这种情况导致第一句话中真实情况的发生，故If only条件句假设的是过去一种情况，因此应该用had +过去分词，所以正确答案是（C）。
12．D．注意主句now表示现在的时间状语，所以主句是对现在虚拟，从句是对过去虚拟。
13．A．从句对过去的虚拟。
14．B．从句表示虚拟，而主句是事实。
17．（D）本道题目的前半句话是对过去情况的一种假设，但事实上并没有发生，而事实上没有发生的真实原因是句子的后半部分由but引导的转折句所表述的真实。因而but所引导的句子中应该用表示志过去事实相符合的表陈述的时态，即一般过去时。
18．（B）此题要求在if从句中选择适当的动词形式，以主句中的动词apologize(抱歉)来看，if从句中表达的内容应该是过去做的事，因此可以排除（A），因为（A）是现在时。（C）中should+have+过去分词结构表示本来应该做却没有做的事，在此不合题意。（D）选项中的might+have+过去分词表示对过去发生的事情很不肯定的猜测，它表达的内容还不能成为事实，所以藉此道歉真是不知从何说起，因此此处也不合题意。（B）had offended表示当时已经发生了的动作。这是复杂条件句：apologize 是现在，而条件句是表示对过去假设的条件句。
19．（A）该句也是一个复杂条件句（或称作混合虚拟条件句）。条件句表示对过去情况的假设，而主句表示对现在情况的假设，但事实上却与此相反，所以正确答案应该是（A）。
20．（A）as if引导的从句要求用虚拟语气，表示同时或将来的情况，动词要用过去式（be动词用were）或would(could等)+动词原形，本句话中指的是当时的情况，所以要用过去式，故（A）是正确答案。
21．D． 22．D． 23．C． 24．A． 25．D．
26．（B）had not occurred表示对过去的虚拟，条件句中要用过去完成式，主句中要用should(would, could, might)+动词原形的过去分词。
27．（B）had hoped是常见的要求其后的宾语从句用虚拟语气的句型,虚拟语气would+动词原形。
28．（C）表示对过去情况的假设，主句动词形式为would(should, could, might)+have+过去分词，条件句为过去完成式，if可以省略，但要把had提前主语前面。（B），（D）的表达不符合英语表达习惯，所以（C）是正确答案。
29．（A）suggest后面的从句要用虚拟语气形式，其形式为should（可以省略）+动词原形。
30．A．表示与现在相反的虚拟。
31．A．as though引导的与过去相反的虚拟。
32．D．felt是过去式，所以该句是由as though引导的与过去相反的虚拟。
33．D．as if引导的与现在事实相反的虚拟。
34．A．as if引导的与过去相反的虚拟。
35．C．
36．（D）would rather后接从句要求用虚拟语气，形式为过去式，表示对现在或将来的假设，或为过去完成式表示对过去的情况的假设。
37．（C）who引导的定语从句中的现在完成时表示动作业已发生，所以主句中表示的虚拟是针对已经发生了的行为，所以应该用过去完成式表示对过去的虚拟。
38．（B）
39．（C）这是一人含蓄虚拟条件句，通过介词短语without,表示潜在的一种假设，而主句中的情况也早已经发生，所以是对过去情况的一种假设，因此用would not have been achieved这一形式。
40．（D）连so that引导的从句中要求用虚拟语气，表示一种假设，形式为might+动词原形。
41．（B）It is time that是一种要求从句用虚拟语气的常见句型。虚拟语气形式为动词的过去式。
42．（C）
43．（C）otherwise用来表示一种含蓄的虚拟假设，因为是对过去(yesterday)的情况的假设，所以应该用would have come形式。
44．（B）所给的四个选项中没有一个表示对未来的情况的虚拟的形式should+动词原形，或是were to do，因此可以断定if引导的条件句在这里最真实的条件句，用一般现在时表示一般将来时，故（B）是正确答案。
45．（A）这是一个混合虚拟语气的句子，if条件句表示的是对过去情况的假设，而主句是对现在（now）的情况的假设，故用would tell形式。
46．C． 47．C． 48．C．
49．B．would rather引导的虚拟语气其谓语用过去式。
50．D．would as soon引导的虚拟语气，其谓语动词也用过去式.
51．B． 52．B． 53．B． 54．B．
55．C．注意单词otherwise引导虚拟语气。
56．C．同上。
57．A．注意词组for fear that
58．A．注意without
59．C． 60．C． 61．D． 62．B． 64．A． 65．D．
