虚拟语气英语中有三种不同的语气:陈述语气,祈使语气和虚拟语气。
虚拟语气表示说话人的主观愿望、猜测、建议或与事实不符的假设等,也可以表示可能性较小的情况或不可能发生的情况,而不是客观存在的事实。
虚拟语气是由句中谓语动词的特殊形式表现出来的。
1、虚拟语气用于条件状语从句中(非真实条件句)1)表示与现在事实相反的情况构成方式:If I were not busy today,I should go with you. 如果我今天有空,我会同你一起去的。
If I had any money with me, I could lend you some. 如果我带钱了,我就会借给你些。
(事实:没有带钱)If he studied harder, he might pass the exam. 如果他再努力些,就能通过考试了。
(事实:没有努力)注:主句的主语为第一人称时,主句中也可用should。
但是美语中一律用would。
might 表示“可能”,可用于主句中的所有人称。
2)表示与过去事实相反的情况构成方式:If I had got there earlier,I should/could have met her. 如果我早到那儿,我就会见到她。
(事实:去晚了)If he had taken my advice,he would not have made such a mistake. 如果他听我的劝告的话,就不会犯这样的错误了。
(事实:没有听我的话)3)表示与将来相反的情况构成方式:If he should come here tomorrow, I would talk to him. 如果他明天来这儿的话,我就跟他谈谈。
(事实:来的可能性很小)If there were a heavy snow next Sunday, we would not go skating.如果下周日下大雪,我们就不能去滑冰了。

如:If it doesn’t rain tomorrow, I will go for a picnic。
假若明天不下雨,我就去野餐.Oil floats if you pour it on water. 你如把油倒在水里,油就浮起来。
虚拟条件句所表的假设则是不可能或不大可能发生或实现的,句中的条件从句与结果主句皆须用虚拟语), 主句的谓语用should (would, might, could)+动词原形。
如:If it were not raining, we should go for a picnic.如果现在不下雨的话,我们就出去野餐了。

)If he came here, he might be able to help you. 如果他来这,他就能够帮助你了。

与现在事实相反的假设通常使用if+主语+助动词的过去式(如were。
did。
had)+动词原形,主句则使用XXX动词原形。
例如:If I had time。
I would XXX。
如果我有时间,我会参加会议。
与过去或将来事实相反的假设则有三种形式:①if+主语+动词过去式;②if+主语+wereto+动词原形;③if+主语+should+动词原形(注意不能是would)。
主句同样使用XXX动词原形。
例如:If you had taken my advice。
you would not have failed in the exam。
如果你听了我的建议,你就不会在考试中失败了。
在错综时间条件句中,动词形式要根据表示时间的状语从句作出相应的调整。

如果我还有上学的机会,我会更加努力研究。
