if条件句

if条件句：条件句用于陈述语气，表示假设的情况可能发生，其中 if 是“如果”的意思，引导条件状语从句，if从句用一般现在时，主句则用一般将来时。 （主将从现） 构成

if从句

主句（主将从现） 1.一般将来时： 主语＋shall/will+V原 2.主句是祈使句

3.主句含有情态动词Can, may , must等词 4.主句含有want, hope , wish 等表愿望的词 I will be busy. call me please.

he will take us to the zoo. please let me know. I may take a trip.

一般现在时：

时态

主+be(is/am/are)+其它（名/形）。 主+V原+其它。

主（三单）+V（三单）+其它。

If I am an teacher, If you come back,

例句

If he comes， If you can come, If I have much money

注意：在与if条件句连用的主句中我们一般用will 表示将来时，而不用be going to 表示将来时。

PS：在when（当…时候）, after, before 等引导的时间状语从句中，如果主句为一般将来时，从句要用一般现在时表示将来（主将从现）。

如： I will call you when I reach Canada. 我一到加拿大就给你打电话。
