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 “ 如果…

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 句,表示假设或条件,意思是 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。 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。 条件从句 If+一般现在时, If he comes, 主句 主语+shall/will+动词原形 he will take us to the zoo.

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 . 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 .

针对练习: ( )1There is going to _________ a soccer match next sunday. If it __________, we’ll have to cancel(取消) it. a. be; will rain b. have; will rain c. be; rains d. have; rains ( )

2.If she _________ harder, she will catch up with us soon. a. study b. studies c. will study d. studied ( )

3.I’m waiting for my mother. __________, i’ll go shopping alone. a. If she comes b. If she will come c. If she doesn’t come d. If she didn’t come ( )

4.I don’t know if he __________ to the party. If he _________, I’ll tell you. a. comes; comes b. will come; will come c. comes; will come d. will come; comes ( )

5. If you don’t go to the party this friday, __________. a. he will, too b. he won’t, either c. he does, too d. he doesn’t, either 二、用所给动词的适当形式填空 1. We ____________ (not go) for a picnic if it rains this sunday.
