求虚拟语气的用法,特别是should型虚拟。

一.should 在含有条件的虚拟语气中的运用

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。

I’d e too if I had time to spare.

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 the hurricane had happened during the daytime there

would have beenmore deaths.

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 I were to met him tomorrowshould, I should ask him about

it.

controlling unit would cut off the fuel oil supply.

二.should在宾语从句中的运用.

1)某些动词后所接宾语从句中的谓语动词要求用虚拟语气,用来
