八年级下册英语第五单元知识点整理
一，课文重难点讲解：
1. If you go to the party, you'll have a good time.
条件状语从句常由从属连词if,unless等引导。

和时间状语从句一样，条件状语从句用一般现在时而不用将来时，尤其注意主语为第三人称单数时，动词使用单数形式。

if引导的条件状语从句的结构：if+一般现在时，主语+将来时。

If you ask him, he will help you.
If it rains tomorrow, we won't go to the park.
I'll go with you if I'm free.
2. I think I'm going to wear jeans to the party.
If you do, the teacher won't let you in.
（1）do用作代动词，代替上文的动词部分“wear jeans to the party”,为避免重复。

Windows let in light and air.
You must keep the door closed. Don't let the dog in.
