请老师讲解一下有if在时,后面什么时候用一般时,什么时候用将来时
解题思路: if引导的条件状语从句
解题过程:
if引导的条件状语从句中:①if意为“如果”,这种句子用来谈论事物的影响,后果。②从句用一般现在时,主句用一般将来时,③从句可放在主句前或主句后,从句置于主句前时,须用逗号与主句隔开,反之则不用逗号。注意:if后面跟的是从句 。
如:If it doesn't rain tomorrow,we will go there by bike.如果明天不下雨,我们就骑自行车去那里。
we will go there by bike是主句用的是一般将来时,而 it doesn't rain tomorrow是从句用一般现在时。
I can see the doctor quickly if I get there early,.如果我早早地到那里,我就可以快点看病。
I can see the doctor quickly是主句用的是一般将来时,而 I get there early是从句用一般现在时。
再如:1.If I get up late, I will be late for school.
2.If I don't finish my homework, I won't go to bed.
最终答案:略
