4、asif,asthough,would(had)rather(that)引导的从句须用虚拟语气，如：

Heactsasifnothinghadhappened.

Iwouldratheryoudidn’ttellhim.

3、wish的用法

IwishIwereapopsinger.(=IamsorryIamnotapopsinger..)

IwishIhadneverstoppedteaching.(=IamsorryIstoppedteaching.)

Iwishthey’dletusgetsomesleep.

注意：wish与hope接宾语从句的区别在于：hope表示一般可以实现的希望，宾语从句用陈述语气。wish表示很难或不大可能实现的希望,宾语从句用虚拟语气。试比较：

(1)Wehopetheywillcome,(Wedon’tknowiftheycancome.)

(2)Wewishtheycouldcome,(Weknowtheyarenotcoming.)

2、Itis(was)+necessary,apity等+that引导的从句须用虚拟语气，其句子结构如下：

Itisimportantthatyou(should)followthedoctor’sorders.

Itisrightthatyoushouldhavedoneyourhomework.

1、Suggest,advise等动词之后宾语从句须用虚拟语气，其句子结构如下：

注意：在此结构中that不可省略；should省不省均可。

He suggested that they(should) stop smoking.

上述动词的名词形式出现时，that引导的从句仍用虚拟语气。

He made are quest that they (should)stop smoking.

如果that引导的从句所表达的内容是事实，也可用陈述语气。

Heinsiststhatheisright.

3.有时条件从句中的动作和结果从句中的动作发生的时间不一致，如：

If he had followed the doctor’s advice, he would be quite all right now.

If I were you ,I would have gone home.

省掉if的条件从句结构：

Had you asked me, I would have told you.(=If you had asked me,…)

2.有时虚拟条件不用条件从句而用不定式、分词、介词、名词、连接词或定语从句来表示，如：

A true friend would not do such a thing.

(=If he were a true friend, he...)

(=If there were no water,…)

(=If you hadn’ t helped me,…)

IfI’ddnownthatitwasgoingtorain,Iwouldneverhavegoneforawalkinthecountry.

Ifyoushouldlose,whatwouldyoudo?

IfIweretoseehertomorrow,Iwouldtellherthetruth.

Ifyouwenttherenexttime,youwouldseewhatImean.

Ifhadthetime,JohnwouldmakeatriptoChinatoseetheGreatWall.

IfIwereyou,Iwouldgiveupdrinkingimmediately.
