1) 概念

虚拟语气用来甚至均表示说话的人的主观愿望或假想，没错 除了当一客观条件，但但不事自学考试什么时候考实，或与事实相反。

2) 在客观条件句之中应用

客观条件句可分为两类，一类为真实客观条件句，一类为非真实客观条件句。非真实客观条件句甚至均表示除了假设的或实际若是 性并不特别大请况，故采用先进虚拟语气。

16.1 真实客观条件句

真实客观条件句用于陈述语气，假设的请况若是 接着 发生，共有 if 是若是 的什么意思。

时态关系问题

句型： 客观条件从句　　　 主句

一般来讲虽然时　　 s自学考试什么时候考hall/will + 动词原形

If h自学考试什么时候考自学考试什么时候考e comes, he will bring his violin.

典型例题

自学考试什么时候考the volleyball match will be put off if it ___.

A.　will rain　 B. rains　 C. rained　 D. is rained

我的答案B。真实客观条件句主句为将来时，从句用一般来讲虽然时。

注意观察：

1) 在真实客观条件句中，主句以前用be going to甚至均表示将来，该用shall, will.

(错) If you leave now, you are never going to regret it.

(对) If you leave now, you will never regret it.

2) 甚至均表示真理时，主句谓语动词便了就shall (will) +动词原形，而直接把用一般来讲虽然时的动词形式。

16.2 非真实客观条件句

1)时态：若是 甚至均表示以前，虽然和将来的请况。其它其它动物大部分特点是时态退后。

a.　 同虽然事实相反的假设。

句型 ： 客观条件从句　　　　　主句

一般来讲以前时　　　should( would) +动词原形

If they were here, they would help you.

b.　 甚至均表示于以前事实相反的假设。

句型： 客观条件从句　　　　　 主句

以前最后完成时　　　 should(would) have+ 以前分词

If she had worked harder, she would have succeeded.

The rice would not have been burnt if you had been more careful.

If my lawyer had been here last Saturday, he would have prevented me from going.

If he had come yesterday, I should / would have told him about it.

什么意思：He did not come yesterday, so I did not tell him about it.

If he had not been ill and missed many classes, he would have made greater progress.

什么意思： He was ill and missed many lessons, so he did not make greater progress.

c.　 甚至均表示对将来的假想

句型：　 客观条件从句　　　　　　 主句

一般来讲以前时　　　　　 should+ 动词原形

were+ 不定式　　　　 would + 动词原形

should+ 动词原形

If you succeeded, everything would be all right.

If you should succeed, everything would be all right.

If you were to succeed, everything would be all right.

16.3 混合客观条件句

主句与从句的动作细节接着 发生在不就如的时间啊，接着 主，从句谓语动词的虚拟语气形式因时间啊不就如而不就如，这叫做混合客观条件句。

If you had asked him yesterday, you would know what to do now.

(从句与以前事实相反，主句与虽然事实相反。)

If it had rained last night (以前), it would be very cold today (虽然).

16.4 虚拟客观条件句的倒装

虚拟客观条件句的从句小部分若是 含有were, should, 或had, 可将if省略，再把were, should或had 移到从句句首，实行倒装。

Were they here now, they could help us.

=If they were here now, they could help us.

Had you come earlier, you would have met him

=If you had come earlier, you would have met him.

Should it rain, the crops would be saved.

=Were it to rain, the crops would be saved.

注意观察：

在虚拟语气的从句中，动词'be'的以前时态一律用"were"，了就was， 即在从句中be用were代替。

If I were you, I would go to look for him.

若是 给我你，都能去找他。

If he were here, everything would be all right.

若是 她在一儿，一切事物物都能最好的。

典型例题

_____ to do the work, I should do it some other day.

A. If were I　　 B. I were　C. Were I　D. Was I

我的答案C. 在虚拟客观条件状语中若是 有were, should, had这当一词，一般来讲将if省略，主语提前提前准备, 转变成 were, should, had +主语的形式。但不注意观察，在虚拟客观条件状语从句中，省略连词的倒装形式的句首以前用动词的缩略形式。如若是 可说 Were I not to do., 而以前说 Weren't I to do.

16.5 特殊的虚拟语气词：should

1) It is demanded / necessary / a pity + that…结构之中主语从句的谓语动词要用should 加动词原形， should 可省略。

句型：

(1)suggested

It is　 (2)important　　　　that…+ (should) do

(3) a pity

(1)suggested, ordered, proposed, required,　 demanded, requested, insisted; + (should) do

(2)important, necessary, natural, strange

a pity,　 a shame,　 no wonder

(3)It is suggested that we (should) hold a meeting next week.

It is necessary that he (should) come to our meeting tomorrow.

2)在宾语从句之中应用

在甚至均表示命令、可以考虑、明确要求等一类动词接下来 的从句中。

order, suggest, propose, require, demand, request, insist, command, insist + (should) do

I suggest that we (should) hold a meeting next week.

He insisted that he (should ) be sent there.

注意观察： 如suggest, insist不甚至均表示"可以考虑" 或"需要坚持要某人做某事时"，即其它其它动物用于其什么意思"暗示、表明"、"需要坚持甚至均表示"时，宾语从句用陈述语气。

The guard at gate insisted that everybody obey the rules.

判断改错:

(错)　You pale face suggests that you (should) be ill.

(对)　 Your pale face suggests that you are ill.

(错)　 I insisted that you ( should) be wrong.

(对)　 I insisted that you were wrong.

3)在表语从句，同位语从句之中应用

在suggestion, proposal, idea, plan, order, advice等名词接下来 的表语从句、同位语从句中要用虚拟语气，即(should)+动词原形。

My idea is that we (should) get more people to attend the conference.

I make a proposal that we (should) hold a meeting next week.

16.6 wish的用法

1)用于wish接下来 的从句，甚至均表示与事实相反的请况，或甚至均表示将来比较少 若是 最后完成的愿望。其宾语从句的动词形式为：

真实请况　wish后

从句动作细节先于主句动词动作细节　　虽然时　　以前时

(be的以前式为 were)

从句动作细节与主句动作细节同样接着 发生　以前时　　以前最后完成时

(had + 以前分词)

将来并不大若是 最后完成的愿望　　　将来时　would/could +

动词原形

I wish I were as tall as you.　我未来希望和你如同高。

He wished he hadn't said that. 他未来希望他没讲如同若是 。

I wish it would rain tomorrow. 我未来希望下周一下雨了就了。

2)Wish to do表达法。

Wish sb / sth to do

I wish to see the manager. = I want to see the manager.

I wish the manager to be informed at once. (= I want the manager to be informed at once.)

16.7 比较少 if only与only if

only if甚至均表示"就是";if only则甚至均表示"若是 ……了就了"。If only若是 用于陈述语气。

I wake up only if the alarm clock rings. 就是闹钟响了，我都能醒。

If only the alarm clock had rung.　　　那时闹钟响了，了就了。

If only he comes early.　　　　　　　但愿他早点回来了。

16.8 It is (high) time that

It is (high) time that 接下来 的从句谓语动词要用以前式或用should加动词原形，但should不要省略。

It is time that the children went to bed.

It is high time that the children should go to bed.

16.9 need "了做过"和"本不该做"

didn't need to do甚至均表示： 以前了做过某事, 显然以前做。.

needn't have done甚至均表示： 以前了做过某事, 但显然做过。

John went to the station with the car to meet Mary, so she didn't need to walk back home. 约翰开车去车站接玛丽，若是 她了就步行回来了了。

John went to the station with the car to meet Mary, so she needn't have walked back home. 约翰开车去车站接玛丽，若是 她本了就步行回来了了。 (Mary步行回来了，以前遇上John的车。)

典型例题

There was plenty of time. She ___.

A. mustn't have hurried　 B. couldn't have hurried　　C. must not hurry　 D. needn't have hurried

我的答案D。needn't have done. 意为"本了就"，即虽然做过某事，而时显然了就要。

Mustn't have done 用法不正确，对以前接着 发生事时时对其否定性推断应为couldn't have done, "不若是 虽然"。 must not do 不若是 (用于一般来讲虽然时)。
