We can walk there if

6、 we cant find a bus . E.g. If it rains tomorrow ,we will not go to the zoo. E.g. 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。E.g. 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
