if 可以用来引导条件状语从句，此时，if 通常表示“假如”。 if 引导的从句既可以放在主句之前也可以放在主句之后。当从句位于主句之前时，常用逗号与主句隔开。
当一个句子中含有if 引导的条件状语从句时，主、从句的时态有如下情形：e.g. If it desn’t rain, I will g fr a picnic.如果从句表示将来要发生的事情，从句通常用___________，主句用___________，即“主将从现”原则。
如果主句中含有will, may, can, might等情态动词时，从句通常用一般现在时。e.g. Yu can g _____________. 如果你想去可以去。
如果主句是祈使句，从句通常用一般现在时。e.g. Please call me if he cmes next  Sunday. 如果他下周日过来请打电话给我。 _________________________ if ______________________________. 如果你不完成作业就不要玩电脑游戏。
yu dn’t finish yur hmewrk
Dn’t play cmputer games
如果表示的是客观事实或普遍真理，从句和主句通常都用一般现在时。e.g. If yu heat ice, it melts. 如果你加热冰，它就会融化。
