If you ask him, he will help you. E.g. If you have finished the homework you can go home. （2）另外，If从句还可以表示不可能实现的条件或根本不存在的条件，也就是一种虚拟的条件或假设。从句多用一般过去或过去完成时，表示对现在或过去的一种假设。E.g. If I were you, I would invite him to the party. E.g. I would have arrived much earlier if I had not been caught in the traffic. 另外还要注意if条件句的时态搭配有以下几种情况：（1） if 从句用一般现在时，主句用一般将来时，e.g. If he runs, hell get there in time. （2）if 从句用一般现在时，主句用may/might/can, E.g. If it stops snowing, we can go out. (3) if 从句用一般现在时，主句用must/should, E.g. If you want to lose weight, you must/should eat less bread. (4) if 从句用一般现在时，主句用一般现在时，E.g. If you heat ice, it turns to water. （也可用will turn） (5) if 从句用现在进行时，主句用一般将来时，E.g. If you are looking for Peter, youll find him upstairs. （6） if 从句用现在完成时，主句用一般将来时，E.g. If you have finished dinner, Ill ask the waiter for the bill. 巧记if用法口诀：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。单项选择( ) 1.
