内 容 详 述

I. 含有条件状语从句的复合句(以do为例;S=主语)

注意事项：

1．倒装句。如果条件句中含有功能词had，should，were时，可以省去If，把功能词提前，构成倒装句。

2．错综条件句。若条件句和主句动作不存在同一个时间，则谓语形式应根据具体情况而定。

3．If there weren't/had not been + =without

4．If it were not for / If it hadn't been for = but for

5．otherwise+虚拟语气的句子

6．虚拟语气的句子，but+ 陈述事实的句子

II. 虚拟语气用在宾语从句中

sb. did (希望现在用过去式)

1. wish+that sb. had done （希望过去用过去完成式）

sb. would/should do（希望将来用过去将来）

2. would rather后的从句要用虚拟语气。

例：I would rather I hadn’t said such unkind things to you. （虚拟过去）

I'd rather you here for the answer tomorrow morning. （虚拟将来）

I’d rather you right away. (虚拟现在)

3. suggest+（that）S+should+do

表示愿望、建议、请求等主观意向的动词之后的宾语从句，谓语用should ＋动词原形，should常常省略。 这类词有：decide，demand，desire，insist，order，propose，suggest，recommend，requested， require等。 注意：

1. suggest 当“建议”讲时，其宾语从句用虚拟语气；当“暗示、表明”时，用陈述语气

2. insist 当坚持“看法或建议”时，宾语从句用虚拟语气；当坚持“某个事实”时，用陈述语气。 判断改错：（错） Your 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.

III. 虚拟语气用在主语从句中

It is demanded / necessary / a pity + that 等结构的主语从句，谓语动词用should 加动词原形，should 可省略。

IV．虚拟语气用在同位语从句中。

某些表示建议、请求、命令等主观意向的名词后同位语从句需用虚拟语气，其表达形式为(should) ＋动词原形。

这类名词常见的有：advice，suggestion，proposal（提议），order， demand，desire，request，requirement，recommendation（推荐），plan，resolution（决议）， idea等。

eg. We are all for your proposal that the discussion ( should )be put off．

V． 虚拟语气用在表语从句中。

某些表示建议、请求、命令等主观意向的名词作主语时，表语从句需用虚拟语气，其表达形式为(should) ＋动词原形。

这类名词常见的有：advice，suggestion，proposal，order， demand，desire，request，requirement，recommendation以及plan，idea，resolution等。

VI． 虚拟语气用在定语从句中

It is（about ／high）time ＋that sb.did sth/should do sth..

eg. Don't you think it's about time we went home？

注：在this is the first time ／second time that．．．句型中，从句中谓语动词用陈述语气完成时态。 eg.Is this the first time that you have visited Hongkong？

VII. 虚拟语气用在让步、方式、目的状语从句中

1．在带有even if/ even though引导的让步状语从句的主从复合句中，主句和从句都用虚拟语气，动词形

式与含有非真实条件句的虚拟语气相同。如: Even if he had been ill, he would have gone to his office. 即使生了病，他俩去办公室。

2．由as if或as though引导的状语从句表示比较或方式时。从句谓语形式为动词的过去式(be用were)

或 “had十过去分词”。如: He treated me as if I were a stranger. 他那样对待我，好像我是陌生人似的。She talked about the film as if she had really seen it. 她谈论那部影片，就好像她确实看过一样。

3．虚拟语气用在lest（唯恐、免得），for fear that及in case引导的目的状语从句中。 在由lest等引导的
