5、ful!小心!Dont forget to close the window.别忘了关窗。Open the door, please.请打开门。虚拟语气表示动作或状态不是客观存在的事实，而是说话人的主观愿望、假设或推测等。如：I were you, I should study English.如果我是你，我就学英语了。I wish you could go with me.但愿你能同我们一起去。May you succeed!祝您成功!（二）虚拟语气在条件从句中的用法条件句有两类，一类是真实条件句，一类是虚拟条件句。如果假设的情况是有可能发生的，就是真实条件句。在这种真实条件句中的谓语用陈述

10、定(有可能)得救。(4)主、从句的动作发生时间不一致的情况有时条件从句中的动作和主句中的动作发生的时间不一致，这时动词的形式要根据它所表示的时间加以调整。If you had listened to the doctor,you would be all right now.如果你当初听了医生的话，身体现在就好了。(从句动作指过去，主句动作指现在)If you had practised speaking English more, you would be able to speak it fluently.如果你多练习讲英语，现在就能讲得很流利了。省略连词if在书面语中，如果虚拟条件从句中
11、有were，had或should，可以把if省略，而把这几个词放到主语之前，构成主谓倒装。如：Should he come(If he should come), tell him to ring me up.他要是来了，让他给我打个电话。Were I you(If I were you),I would not do it.我要是你，就不做这事。Had he been more careful(If he had been more careful), such mistakes could have been avoided.如果他细心些，这些错误本来是可以避免的。在虚拟条件句中，省略连词
12、的倒装形式，其句首不能用助动词的缩略否定式。如我们可以说：Were it not for the expense, I would go to Paris. 但不能说： Werent it for the expense,I would go to Paris.用介词短语代替条件状语从句有时假设的情况并不用条件从句表示出来，而是通过介词短语来表示。如：Without air(If there were no air), there would be no living things.如果没有空气的话，就不会有生物了。But for your help(If it hadnt been for
13、your help)I couldn?t have done it.要是没有你的帮助，我就不可能完成这件事。假设的情况有时可以通过上下文或其他方式表现出来。如：I was busy that day. Otherwise I would have gone there with them. (If I hadnt been busy that day, I would have gone there with them. )我那天很忙，否则，我就和他们一起去那儿了。(如果我那天不忙的话，我就)I would have finished the work, but I have been ill
