关于if虚拟语气的一个句子
一、判断是真实条件句还是非真实条件句。
只有在非真实条件句中才使用虚拟语气。
通过句子意思,看假设的条件是否能够实现,能够实现是真实条件句,不能使用虚拟语气;假设的条件不能实现则是非真实条件句,要用虚拟语气:①与过去事实相反,在从句中用过去完成时形式表示。
②与现在事实相反,在从句中用过去一般时形式表示。
③与将来事实可能相反,在从句中用过去将来时形式表示。
二、表示与现在事实相反的情况。
其句子结构为:从句:if+ 主语+ 动词的过去式(be 用were) + ……主句:主语+would (should, could , might) + 动词原形+ ……例:1.If I were you, I would go with him.2.If the weather were fine, I would go there.如果天气好,我去那儿。
(事实天气不好)3.If I were you, I would read it again.如果我是你的话,我再读一遍。
(事实上我不是你)4.If time permitted, I would write it again.如果时间允许的话,我再写一遍。
(事实上时间不允许)5.If it weren’t snowing, we wouldn’t stay in the house.要是现在不下雪的话,我们就不会待在屋里。
(事实上现在下雪)6.What would I do if I were in your place?要是我处于你地位我会怎么办
(事实上我不在你的位置上)7.If he hurried, he could catch the first bus.他要是快点能够赶上头班公共汽车。
(可是他不着急)8.If it weren’t for your help, we would get into trouble.如果没有你们的帮助,我们就会陷入困境。
(而事实上得到了你们的帮助)9.If we had the manpower, we could open up even more land.如果有人力,我们还能开更多的荒地.10. If I were you, I would go with him.(从句If I were you, 主句I would go with him.)11. If I were you, I should buy it.(从句用过去式动词were,主句用动词原形buy)12. If I had time, I would study French.(如果有时间,我会学习法文。
)(从句用过去式动词had,主句用动词原形study)13. If she knew English, she would not ask me for help.(如果她懂英文,她就不必要我帮了。
)(从句用过去式动词knew, 主句用动词原形ask)注意:如果动作在进行中,主句要用:主语+ would be + 进行式动词+ ……14. If they were here, he would be speaking to them now.(从句用过去式动词were, 主句用would be speaking)
if条件句一定要用虚拟语气么
If 引导的是条件状语从句件状语从句分两种:真件句,非真实条件句者就是“虚拟语气”。
你的这句话If you work hard,you will succeed 是真实条件句,可能实现的事情,不是虚拟。
虚拟的意思是:对不可能情况的假设,比如,如果我是你,我就如何如何。
我永远不可能是你。
虚拟。
再比如:如果今天晚上就是世界末日,剩下的时间你要做点什么
如果现在我们站在火星上,.....如果天上下的不是雨(实际情况现在正在小雨),而是火....以上这些情况,就都用虚拟语气了。
虚拟语气if 解释一下这句话(*悬赏*)
1. 当if后面接一般现在时的动词时,表示对将来的一种推测. if sb do sth sb will\\\/shall do sth. If you go with me, you shall be rewarded. 2. 当if后面接一般过去时的动词时,则是一种虚拟语气. if sb did sth sb would\\\/should do sth. If I didn't make that mistake, I would't have suffered such a failure. 3. 当if后面接什么时态都可以时,if为“是否”的意思,句子为宾语从句. sb do sth if sb do sth. He said if rain was stop. 由if引导的条件状语从句,时态应该是主将从现,就是说主句用一般将来时,而从句用一般现在时表示将来。
例如 If it doesn't rain tomorrow, I will visit my former school. 这里从句就用一般现在时。
当然if引导的从句也可以用虚拟语气 例如If I got up early in the morning, I wouldn't miss the train.
