Step 3  Grammar summary

含有if引导的条件状语从句的复合句

if引导的条件状语从句，可以放在主句之前，也可以放在主句之后。放在主句之前时用逗号隔开。

If he doesn’t work hard, he will fail the exams.

他如果不努力学习，就会考试不及格。

We can take a walk if the snow stops. 如果雪停了，我们可以去散步。

[注意]

在含if引导的条件状语从句的复合句中，如果主句是一般将来时，从句通常用一般现在时表将来。助记口诀：时间条件，主将从现。（时间：时间状语从句）

[拓展]

Girl: The problem is I fall asleep very late, and in the morning when I have to get up and go to school, I’m too tired!

Doctor: Yes, that’s a problem. And you do need enough sleep when you’re still growing.
