The boy insisted that he（should）go back alone．这孩子坚持要一个人回去。
2．凡是由“It is（was）requested（ordered，suggested，desired，decided等）that…”引导的名词性主语从句中，其谓语部分的should可以省略。例如：

It is desired that the bridge（should）be built in
two years．要求两年内建成这座桥。
It has been decided that the meeting（should）be held
tomorrow已经决定会议明天举行。

It is necessary that our college students（should）master a foreign language．
我们大学生掌握一门外语是很必要的。
4．凡是主句中有以suggest，proposal，order，idea，plan，news，motion，demand等名词后面所带的表语从句或同位语从句中，其谓语部分的should可以省略。例如：

tomorrow．你建议我们明天去参观长城，他们正讨论。
5．凡是由lest（以免；免得），in case（以防）和 for fear that（生怕，唯恐）引导的目的状语从句中，其谓语部分should可以省略。例如：

English．她现在很勤 奋，生怕英语不及格。

虚拟语气用来表示假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气通过谓语动词的特殊形式来表示。英语中的语气分为陈述语气、祈使语气、虚拟语气三类。虚拟语气表示说话者做出的假设并非事实，或难以实现的，甚至表达相反的概念。另外表示主观愿望或表达某种强烈的感情时，也用虚拟语气。
在表示假想的虚假的、与事实相反的或难以实现的情况时用虚拟语气，表示主观愿望或某种强烈情感时，也用虚拟语气。即当一个人说话时欲强调其所说的话是基于自己的主观想法，愿望，假想，猜测，怀疑或建议，而不是根据客观实际，就用虚拟语气。主要是英语语法的一种表达。

If I’d left sooner，I’d have been on time.要是我早点动身，我就准时到了。(但我动身太迟了)
