对将来进行假设主要有三种情况：

1,if条件从句是谓语用动词过去式,则后面的主句是情态动词加动词原形

例：If I came tomorrow ,we would have the meeting.

2,if条件从句是were to形式,则后面的主句也是情态动词加动词原形

例：If it were to rain tomorrow ,the meting would be put off.

3,if条件从句是should do形式,则后面的主句可以用情态动词加动词原形,也可以用祈使句（但注意,祈使句仅适用于前面从句是should do形式的）

例：If it should rain tomorrow,don't expect me./I would not go there.

如果他再努力些，就能通过考试了。（事实：没有努力）

If I were you， I'd wear a shirt and tie.

如果我是你，我就会穿衬衫和领带。(事实：我并不是你）

2、表示与过去事实相反的情况

从句：If+主语+had+done

主句：主语+should/would/might/could+have done

eg：If I had got there earlier，I should/would have met her.

如果我早到那儿，我就会见到她。（事实：去晚了）
