if引导的条件状语从句
引导条件状语从句最常用的连词是if,常见的if条件状语从句表示在某条件下,某事很可能发生,条件是可能存在的,主句中某种情况发生的概率也是很高的。

1.if引导的条件状语从句的构成。
构成:“主句+if引导的条件状语从句”或“if引导的条件状语从句+主句”。在含有条件状语从句的复合句中,如果主句在前,从句在后,主从句之间不用标点;如果要强调从句的内容,则把从句放在主句的前面,这时主从句之间要用逗号隔开。
I will go to his birthday party if he invites me.
=If he invites me,I will go to his birthday party.如果他邀请我,我将去他的生日宴会。
2.if引导的条件状语从句的时态。
在一般情况下,如果主句谓语动词表示将来的意义,从句谓语动词用一般现在时表示将来。常见的有以下几种:
(1)主句是一般将来时。
You will be late for school if you get up late.
如果你起晚了,上学将会迟到。
If it rains tomorrow,we won’t go to the Great Wall.如果明天下雨,我们就不去长城。
(2)主句的谓语动词是want,hope,wish等词。
I hope to visit her if I’m free.
如果我有空,我希望去拜访她。
(3)主句的谓语动词含can,may,must等情态动词。
If I finish my homework,I can watch TV.
如果我完成了我的家庭作业,就可以看电视。
(4)主句是祈使句。
Don’t forget to lock the door if you are the last one to leave.如果你最后一个离开,别忘了锁门。
