2、would(could/should/might)动词原形 If she knew English，she wouldnt ask me for help. 如果她懂英语的话，她不会找我帮忙的。 If I were you，I would go to hospital. 如果我是你，我会去医院的。 If I had known her number，I would have called her. 如果我知道她的电话号码的话，我就给她打电话了。 If it were to snow this evening，they would not go out. 如果今晚下雪，他们将不出去了。 注意：(

3、1)在书面语中，如果虚拟条件从句中有were，助动词had或should，可以把if省略，而把这几个词放到主语之前，构成倒装结构。 Were it necessary，I might resign. 如果需要的话，我可以辞职。 Should they have patience，they could do the work well. 如果他们有耐心的话，他们就可能把这项工作做好。 Had he worked harder，he would have got through the exams. 他当时要是学习努力点的话，就会通过这些考试了。 Were she to move right no

4、w，she would get there on Sunday. 她要是马上动身的话，星期天就可以到那儿了。 (2)当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，被称为“错综时间条件句”，动词的形式要根据它所表示的时间做出相应的调整。 If you had followed my advice just now，you would be better now. 如果你刚才接受我的建议，你现在会好些。 If you had studied hard before，you would be college student now. 如果你从前努力学习，你现在会是一名大学生。 无“条

5、件”虚拟语气句子 无“条件”是指没有if或I wish等引起表条件的句子，而是用其他形式表现出来，如介词、形容词、名词、代词、连词、动词、分词、从句或上下文等。常用来表示“无条件”的词有：with；without，but for，or，but，otherwise，even，in case of，what if(如果将如何/倘若)。 But for your help，we couldnt have succeeded. 要不是你的帮助，我们是不会成功的。 She wasnt feeling well，otherwise she wouldnt have left the meeting so

7、I wish she had taken my advice. 那时她要是听我的话就好了。 (2)用在表示建议、愿望、命令等词后的宾语从句中。常见的动词有：suggest，advise，propose，mand，request，insist，remend等，宾语从句中谓语动词用should动词原形，should可以省略。 She insisted that the seats (should) be booked in advance. 她坚持要预订座位。 He demands that he (should) be told everything. 他要求将一切告诉他。 注意：如果上述动词作
