英语语法:虚拟语气(二)

  1. 一些要求用“过去式或过去完成式”来表示虚拟的固定句式. 过去式表示与现在事实相反;过去完成式表示与过去事实相反.它们有:
       
       
                  (1)wish + 从句
       
       
                  (2)主 + would rather + sb + V .
       
       
                  (3)It’s ( high ) time that …(只用过去时)
       
       
                  (4)If only +从句
       
       
                  2.用(should )+(原形)来表示虚拟的情况
       
       
                  虚拟语气在动词suggest, desire, require, command, propose, order, insist, request,
等表示“请求,建议,命令,要求”后面的宾语从句中用“should +动词原形”, should可以省略。
       
       
                  Note: suggest表示“表明”时不用虚拟语气.
       
       
                  All the evidence suggested that he stole the money.
       
       
                  3. 表示祝愿
       
       
                  1) wish + adj./n.
       
       
                  2) may+动词原形, 此时may只能放于句首.
       
       
                  Note: I wish that…不是表示祝愿, 但动词原形可表示祝愿.
