名词性从句中的虚拟语气的用法解析

名词性从句中的虚拟语气

当名词性从句（主语从句、宾语从句、表语从句和 同位语从句）中的
谓语动词使用了某种特殊形式或者该从句使用了某些具有特定意义的名
词、形 容词或分词时，可以使用虚拟语气。

1. 主语从句
(1) It is important that she (should) cooperate with us
It was unnecessary that he (should) get here so early.
He says it is fortunate that she (should) take the first
prize.
It is strange that he (should) leave without telling us.
It is surprisingamazingpleasing that she(should) win over
her mother.
在“it + be + adj. + that clause ”的句型中，形容词表示“必须
的”、“重要的”、“适 当的”、“自然的”、“不可能的”、“紧迫的”等意义时，
主语从句常用虚拟语气。这类形容词还有a dvisable, desirable, essential,
impossible, natural, possible等。形容词表示“惊讶的”、“失望的”、“懊
悔的”等意义时， 主语从句常用虚拟语气。形容词是dreadful（可怕的），
funny等词时，这种句型中的主语 从句也可用陈述语气。

（2）It is ordered that the classroom (should) be kept in order.

1

It is desired that every student (should) obey the school
rules
It is suggested that we (should) start the work at once.


表示“命令”、“建议”、“要求”意义的动词，如advise, arrange, demand,
propose, recommend, request, require等用被动语态时，主语从句要
用虚拟语气。
2. 宾语从句
（1）He insisted that all of us (should) be there on time by any
means.
The teacher suggested we (should) clean the blackboard after
class.
表示“要求”、“建议”、“命令”等意义的动词后的宾语从句要用虚拟
语气。这类动词包括insist, desire, request, order, propose,
command, advise, recommend, demand, suggest等。这些动词后面的
宾语从句中用“（should）+ 动词原形”构成虚拟语气。

注意：当insist 表示“坚持认为”和suggest表示“表明； 暗示”，
其后的宾语从句中不用虚拟语气。例如：
The look on his face suggested that he was quite satisfied with
what I had done for him.

2

He insisted that was honest.
(2) I wish I could fly.（用一般过去时表示与现在事实相反的愿望）
I wish I had known it before. (用过去完成时表示过去未实现的
愿望，即与过去事实相反的愿望)

I wish you would stay a little longer. (用“would + 动词
原形”表示对将来的愿望) Wish 后的宾语从句常用虚拟语气。Wish
后面宾语从 句中的虚拟语气，要按“后退一步法”处理从句中谓语动
词的时态。

注意：表示何 时的愿望，与那个事实相反，不能以主句时态为判断依
据，而应根据从句的意义判断。

（3） I would rather you did not make any comment on the issue
for the time being.
Would not you rather your child went to bed early? 短语would
rather后面的宾语从句中常用虚拟语气。在这种结构中，从句中的谓
语 动词通常用过去式表示对现在的虚拟，用过去完成时表示对过去的
虚拟。

3．表语从句
My suggestion is that the old houses (should) be pulled down.

3

The old man’s request is that his children (should) give him
some money to live on every month.
句子主语是表示“愿望”、“劝告”、“建议”、“主张”、“决定 ”等
行为动词派生出的同根名词时，表语从句常用虚拟语气“（should+） 动
词原形”结构。这类名词有suggestion, proposal, request, advice,
decision, requirement等。

4. 同位语从句
What do you think of Mr Li’s proposal that we (should) have
a get—together next Friday?
My wish that a teaching building (should) be built here will
soon come true. 同位语从句中用虚拟语气的情况与表语从句类似。从句的先行词
是表示“愿望”、“劝告”、“建议 ”、“主张”、“命令”、“决定”等行为
动词派生出来的同根名词时，同位语从句常用虚拟语气“（s hould+） 动
词原形”结构。这类名词与上面所讲的表语从句中的一样。
补充： It is (high) time that the child went to bed.
在it is (high) time + (that)从句中，从句中的谓语动词通常
用过去时（或should+动词原形）表示虚拟。
