Our teacher insisted that we ____ in class. A. not to talk B. don't talk C. should not talk D. not talk
郑孝通编著的《“高中英语”重点·难点纵横谈》(二)(中国科技大学出版社,p.61)在解答上道题时说：
“insist that...，后面可以加 should，也可省略，动词用原形。但用在 should not 时，则不能省略 should”。
由此看来,上题的唯一正确答案,只能是 C(should not talk)。请问果真是这样吗?
上面的解释把两种不同的结构混同为一种结构了。实际上，在上面的 that 从句中使用现在虚拟式和 should 结构都是正确的。在使用第一种结构时，that 从句如为否定句，则否定词 not 应放在动词之前，例如：
-
They insisted that we not eat meat. 他们坚持不让我们吃肉。
-
Jean's uncle insists that he not stay in this hotel. 琼的叔父坚持不住这家旅馆。
由此可见,上道题中的选择项 D(not talk) 也同样是正确的。
请做下面的英语试题：
-
Mike's uncle insists ____ in this hotel. A. staying not B. not to stay C. that he would not stay D. that he not stay(全国四级,00.1-52)
-
It was recommended that passengers ____ smoke during the flight. A. not B. need not C. could not D. would not(全国英语专业四级,94-58)
