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.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。

还要注意前后时态一致原则if 条件状语从句的时态练习一．在正确的答案下划一条线。
