优质解答：

1.

虚拟现在时表示与现在事实相反的假设,其if 从句的谓语形式用动词的过去式(be 一般用were),主句用would/ should/ could/ might

+动词原形.If places were alike,there would be little need for

geographers.如果各个地方都一样,就不需要地理学家了.

2.

虚拟过去时是表示与过去事实相反的假设,if 从句的谓语形式用过去完成时即had＋过去分词,主句用would / should / could / might +

have +过去分词.If he had known your address yesterday,he would have telephoned

you.

3.

虚拟将来时是表示对将来实现的可能性很小的或不确定的假设.If从句的谓语形式用一般过去式或用were to / should +动词原形,主句用would /

should/could/ might +动词原形.If he were to leave today,he would get there by
