二、在表示建议、命令、要求、忠告等动词的后面的宾语从句中的虚拟语气

由于这些动词本身隐含说话者的主观意见，认为某事应该或不应该怎样，这些词语后面的“that”从句应用虚拟语气，且均以“should+动词原形”表示这种语气，但事实上“should”常被省略，故此从句中谓语动词用原形，常用的此类动词有：

表示“要求”的：ask, desire, request, demand, require, beg

表示“提议、劝告、建议”的：move, prpose, suggest, recommend, advise, vote

表示“决定、命令”的：decide, order

表示“主张”的：maintain, urge

表示“同意、坚持”的：consent, insist

例如：

1.The doctor suggested that he (should) try to lose his weight.

2.He insisted that we (should ) tell him the news.

3.When I suggested that he try shaving cream, he said, “The razor and water do the job. ”(当我建议他用刮胡膏时，他说“剃刀和水就行了”。)

4.He pursued various theories for several days until I suggested we take the toy apart to see how it did work. (他费了几天功夫寻找理论根据，直到我建议拆开看看它是如何转动的。)

5.One can suggest that students should spend two or three years in an English?speaking country. (我们建议学生应在说英语的国家呆上两三年。)

在表示命令、建议、要求等一类动词后面的从句中虚拟语气很普遍，其结构如：

order, suggest, propose, require, demand, request, insist, command, insist +... (should) do

6.I suggest that we (should) hold a meeting next week.

7.He insisted that he (should ) be sent there.

但注意：在insist 后的从句中, 如果是坚持自己, 用陈述语气, 坚持别人做什么事情, 用虚拟语气.

8.she insists that she is right.

9.she insisted that I should finish the work at once.

或者说，suggest, insist不表示建议或坚持要某人做某事时，即它们用于其本意暗示、表明、坚持认为时，宾语从句用陈述语气。

10.The guard at gate insisted that everybody obey the rules.　

判断改错:

(错)11.　You pale face suggests that you (should) be ill.

(对)12.　Your pale face suggests that you are ill.

(错)13.　I insisted that you ( should) be wrong.

(对)14.　I insisted that you were wrong.

例题分析：15.It is politely requested by the hotel management that radios ______ after 11 o"clock at night.

A. were not played B. not be played

C. not to play D. did not play

全句意思是：“旅馆管理部门恳请客人晚上11点后不要打开收音机”。句中的谓语动词request（请求）所引出的从句应当用虚拟语气，即动词原形或“should＋动词原形”。本句的主语从句中，主语radio是谓语动词play 的客体，谓语应当用被动语态。所以，答案是C) not be played。在上述这类句子中不能用动词过去时形式表示虚拟语气，所以A)不正确。选项B) not to play是动词带to的不定式，不能在句中作谓语。选项D)did not play也是动词play的过去时形式，同样不能在本句中作为虚拟语气来使用。而且，它是主动语态形式，而本题要用被动语态。

练习：

16). The chairman requested that .

［A］the members studied more carefully the problem

［B］the problem was more carefulnessly studied

［C］with more carefulness the problem could be studied

［D］the members study the problem more carefully

17). The committee recommends that the matter at the next meeting .

［A］would be discussed

［B］will be discussed

［C］be discussed

［D］may be discussed

18). The doctor insisted that his patient .

［A］that he not work too hard for three months

［B］take it easy for three months

［C］taking it easy inside of three months

［D］to take some vacations for three months

三、在expect, believe, think, suspect等动词的否定或疑问形式后的宾语从句中的虚拟语气

在expect, believe, think, suspect等动词的否定或疑问形式后的宾语从句中，我们经常用“should＋动词原形(或完成形式)”，表示惊奇，怀疑，不满等。

I never thought that he should be such a brave young soldier.

我们从来没想到他是个如此勇敢的小战士。

练习：

1) that the time will soon be ripe for intervention in Iran，they would be faced by a large army?

［A］It is believed

［B］Should they believe

［C］They would believe

［D］If they would believe

2) I think it advisable that he for Tokyo soon.

［A］will leave

［B］may leave

［C］leave

［D］leaves
