八年级下册Unit 5 单元笔记
I .语法小结
  . 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如果的意思。
构成
条件从句
主句
时态
If+一般现在时
主语+shall/will+动词原形
例句

he will take us to the zoo.

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shallwill
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.
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
