高中英语语法|虚拟语气

1.       规则虚拟:即含if 从句的复合句,表示与事实相反。(见表格)

时间

if从句

主句

对将来

Did(were) / were to + do / should + do

would / could / might / should + do

对现在

did(were)

同上

对过去

had done

would / could / might / should + have done

 

注意:

1) 交叉时间虚拟:即主、从句不在同一时间,注意各自的时态。

2) 虚拟中的倒装:如if从句中含should, had, were等,可将其置于句首,且省略if

3) 介短、副词代替if从句:如without, but for, in the absence of (如果没有), or, otherwise

2. 表示建议要求、劝告、命令类词 + 名从中的虚拟,从句动词:(should) do

  适用词群:advise, demand, desire, , insist, order, propose, recommend, require, suggest, urge等及其它们的名词、形容词、过去分词等,后跟名从。

   注意:当insist为“坚持已发生或存在的事实”,suggest为“暗示、表明”时,要用陈述语气,即实际时态。

3. wish等词 + 从句:从句时态向后退一格: 即表示现在用did / were / was; 表示过去用had done

适用词群:wish, as if /though, If only(要……就好了), would rather, It is (about / high) time 等。

4. 情态动词 + have done 表虚拟:

should / ought to have done 本应该做(实际没做,含“责备”之意)

could / might have done 本可以做(实际未做)

needn’t have done 本没必要做 (实际做了)

would like / love to have done   

would rather have done        本来想要做某事(

had better have done            未做)

mean/intend to have done          

 

5. 句型:

1) If it were not for…, I would / should / might / could + do

    “要不是……,我现在就……。”(对现在的虚拟)

   If it had not been for…, I would / should / might / could + have done.

    “要不是……,我当时就……。”(对过去的虚拟)

2) It is important / necessary / natural / strange /essential…+ 从句

     It is a shame / pity / no wonder…+ 从句.

     以上从句谓语动词皆为:(should) do

3) had hoped / expected / intended / planned /…+ to do 本希望 / 打算做……(但未做成)
