名词性从句与特定句型中的虚拟语气
一、表示“建议、命令、要求”的动词后宾语从句
在表示建议(suggest, advise)、命令(order, command)、要求(demand, require, request)、坚持(insist)等动词后的宾语从句及同位语从句中,谓语动词使用 (should) + 动词原形:
- The doctor suggested that he (should) get more rest.
- It is demanded that all students (should) attend the meeting.
二、其他常见虚拟句型
- wish 后的宾语从句:
- 与现在相反:用一般过去时(I wish I knew the answer.)
- 与过去相反:用过去完成时(I wish I had met you earlier.)
- 与将来相反:用
would / could + do
- as if / as though 引导的从句:从句情况非真实时用虚拟语气。
- It is (high) time that + 主语 + 过去式 / should do:意为“该是做某事的时候了”。
