" if " 引导的条件状语从句" if " 引导的条件状语从句的用法,现在总结一下:if 条件句不一般,几个要点记心间;条件句,放在前,逗号要放句中间。
条件句表可能，主句多用将来时；条件句表事实，主句常用现在时。
在if 引导的条件状语从句中，如果从句谈论的是一个有可能发生的事实及其产生的相关的结果，主句用一般将来时态，从句用一般现在时态。
如：We can walk there if we can't find a bus .If it rains tomorrow，we will not go to the zoo.What will you do if you find a panda in danger.如果if 条件句谈论的是重复发生和预示要发生的情景和事件，则主从句大多用一般现在时态。
如：If bears are in danger，they attack people.注意：在if 引导的条件状语从句中，if 和条件句位置灵活，可直接放在主句后面，若if 条件句放句首，从句后面要加逗号，和主句隔开。
