if 条件状语从句的时态练习
观察与思考：观察1a中含有if的句子，你发现主句和从句的特点吗？if引导的是一个条件句，主句用__________(时态)，从句用__________(时态)。

注意：在与if条件句连用的主句中我们一般用will 表示将来时，而不用be going to 表示将来时。

(1) if引导的条件句位置灵活，可直接放在主句后面。

若if引导的从句在前时，应在句中加__________(标点符号)。

(2) 如果if条件句谈论的是今后可能出现的情况，则主句大多用_______时；若if条件句谈论的是客观事实，则主句大多用_________时或含情态动词的句子。

(3) 在if条件句中通常用________时代替一般将来时表将来。
