关于虚拟语气的构成
对将来的事实的虚拟语气,构成是什么 要几个例句是几个
答
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.
