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.
