考点一:if 引导的条件状语从句

【考例】 If_________, I will go.

A. he doesn’t come B. he won’t come C. he will come D. he is coming

if 引导的条件状语从句。If是连词,所连接的句子 叫条件状语 从句,表示假设或条件,意思是 “ 如果…的话”,用法如下:

1、表示假设,表示将会发生和可能发生的事,或进行提醒警告。

用法:

(1)条件状语从句通常由连词if引导,意为“如果、假如”,主句不能用be going to表示将来,而应该用shall,will。 如: If you go to the party, you will meet Uncle Zhang.

I’ll ask the teacher for help if I don’t understand.

(2)if “如果”,引导条件状语从句,主句用一般将来时,从句则用一般现在时。如:

If it rains tomorrow, we won’t go there. 如果明天下雨,我们就不去那了。

(3)若主句是祈使句,if引导的条件状语从句仍用____________时态。

Put up your hand if you have any questions to ask.

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“是否”相当于 whether,引导宾语从句,时态需根据语境确定。

如:I don't know if it will rain tomorrow. 我不知道明天是否会下雨。

2. 表示真实条件、客观真理、自然现象、定理定义 . 民 间谚语等,句型是:

If + 句子 (一般现在时 ),+ 主句 ( 一般现在时).

例: If you study hard ,you are sure to succeed .

If you put ice in a warm place ,it turns into water .
