为什么有的宾语从句中要用虚拟语气

Question

如题所述

Answer 1

E.虚拟语气在宾语从句中:
1.记住: 这些动词后面接的宾语从句:表示愿望(wish),建议(suggest, advice, propose. recommend),要求(demand ,request, require, insist),命令(order, command)等.此时无论主语是什么，谓语都要用should + do构成, should可以省略.
如：They demanded that the right to vote(should) be given to every adult man.(他们要求给予每个成年男子选举权。)
又如：Rose insisted that the girl (should) be sent to hospital.罗斯坚决要求这个女孩要被送往医院。
再如：He ordered that the students wash the clothes every week by themselves.
他要求学生每周都要自己洗衣服.

注意：记住: insist/suggest各有两种意思, 要用不同的语气
insist表示“坚决要求”时，用虚拟形式，而表示“坚持说”时，用陈述语气，表示事实。
suggest表示 “建议”时，用虚拟形式；而表示“表明、暗示”时，用陈述语气。
例句：
The teacher suggested that we (should) clean the blackboard after class.
老师建议我们课后把黑板擦了。
Her face suggested that she was still angry with her husband.
她的脸色表明她和她的丈夫还很生气。
He insisted that all of us should be there on time by any means.
他坚持要我们大家想尽办法按时去那儿。
He insisted that he was right.他坚持说他是对的。

2. wish 接宾语从句有三种情况:
1).若表示现在: 动词用过去式；2).若表示过去: 动词用过去完成式(had done)；3).若表示将来: 用情态动词(would/could) +do
例句:
① I wish she would be on my side. 我希望她能站在我一边.
② I wish I were 30 years younger. 我但愿自己能年轻三十岁.
③ I wish (that) you would get a good job. 但愿你能找到一个好职业.
④ He wished he hadn’t done it. 他想要是他没这样做该多好.

A.在would rather(宁愿)引导的的宾语从句中：
该句型表示“宁愿、宁可”，语气较为委婉。当从句表示现在或将来的时间时，谓语动词要用一般过去时；表示过去时间时，要用过去完成时。
E.g. I would rather they left on an early train.(表现在)
I would rather he hadn't told me about it.(表过去)

请注意对比：would rather do A than do B.宁愿做A也不愿做B。
如：He would rather walk to school than go to school by bus.
