．语法小结
一. if条件句
1. 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。
2. 用法：
(1)条件状语从句通常由连词if引导，意为“如果、假如”.主句用shall或will。
行政文员If you leave now, you will never regret it.
(2)if “如果”，引导条件状语从句，if从句则用一般现在时，主句用一般将来时。以上用法简称为“主将从现”。
If it rains tomorrow, I won’t climb the hills.
If I go to college, I will never become a great soccer player.
三阶交调
注意宾语从句中的if与条件状语从句if的区别。宾语从句中的if译为“是否”,而本单元条件状语从句中的if译为“如果”
I don't know if it will rain tomorrow. If it rains, I will have to stay at home
我不知道明天是否会下雨.如果明天下雨的话，我将不得不呆在家里。
