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 .
