    在lest that, for fear that, in case that等引导的表示消极意义的目的状语从句中,常常用到虚拟语气,结构用should+动词原形,且should能省略。例如:I keep some candle in the house in case that electric power should fail.

    由would rather/sooner, would sooner, had rather, would just as soon, would prefer等结构引导的虚拟语气,其句型结构是这样的:如果与过去事实相反,用"would rather/sooner...谓语动词用had done";如果与现在、将来事实相反,用"would rather/sooner...谓语动词用did"。

    如果使用虚拟语气,在so that, in order that所引导的目的状语从句中,从句中的谓语为:can/could/may/might/will/would/should+do.比如:He goes closer to the speaker so that he can hear him clearer./He read the letter carefully in order that he should not miss a word.

    当insist意为"坚持某种动作"时,才需要用虚拟语气。如果它的意思是"坚持某种观点,某个事实",就不需要用虚拟语气了。比如:He insists he is a student.这个语句表示的是事实,因此在这个语句中不能使用虚拟语气。
