中考书面表达写作指导:虚拟语气语法
一.虚拟语气用于条件状语从句中
1. 表示与现在事实相反或不可能发生:条件状语从句:一般过去时(虚拟语气中be→were)主句用:would(should, could, might)+动词原形。
If we had time now, we would read it again.
If I were you, I would work hard.
2. 表示与过去事实相反或不可能发生:条件状语从句:had+过去分词;主句:would(should, could, might)+have+过去分词。
If he had taken my advice, he would have succeeded in the test.
If I had known your telephone number then, I would have called you.
3. 表示与将来的事实可能相反或不可能发生:条件状语从句:①一般过去时②should +动词原形③were to+动词原形;主句:would(should, could, might)+动词原形。
If it should rain, the crops would be saved.
If it w ……此处隐藏551个字……glish well as if he had studied in America.
He learns English so hard as if he would go abroad.
2.在it is (high) time that …句型中也用虚拟语气,从句常用过去式,有时也用should +动词原形,表示早该做而没做的事,含建议的意味。
It is time that we went home.
P.S.此句型中,注意与‘It/This is the +序数词+time that+现在完成式的区别。
This is the first time that I have been here.
3.would rather后接动词原形,但接从句时要用虚拟语气(宁愿,但愿)。
Would rather +主语+一般过去时(表示与现在或将来相反)
Would rather +主语+过去完成时(表示与过去相反)
I’d rather he didn’t go now.
I’d rather you hadn’t done it.
4. if only后接从句也用虚拟语气,其形式与wish的用法一致。
5. 动词hope, intend, mean, plan, want, think等词用过去完成的形式,表示的意思为‘本想,本打算,本认为’
He had meant to buy the furniture last week, but it rained.
(他上周本打算去买那件家具,但却下雨了)
