It looks as if it___ rain.going to 请问这是对什么时候的虚拟?

问题描述:

It looks as if it___ rain.going to 请问这是对什么时候的虚拟?

这个没有用到虚拟语气.
句子的意思是天看上去要下雨了,用将来时.怎么看出来不是虚拟?为什么这句就用虚拟了she looks as if she would cry.虚拟语气是表示说的话不是事实,或不可能发生,只是一种愿望、假设或建议等。she looks as if she would cry和It looks as if it___ rain. look是感官动词,作系动词用,所以它后面跟的句子是表语从句。虽然as if也是虚拟语气在状语从句中的引导词,如:People treat me as if I were a dangerous person.你可以发现这句用了虚拟语气,因为主句和从句的时态是不一致的。虚拟语气的标志是主从句的时态不一致。she looks as if she would cry.那这句时态前后也不一致,是虚拟?不是,虽然前后不一致,但是这句是表语从句,有would是语气委婉。
