_____in the regulation that you should not tell other people

此题是05年上海高考第38题 答案是C
38__________ in the regulations that you should not tell other people the password of your e-mail account.
A.What is required B.What requires C.It is required D.It requires
此题考察的是主语从句的应用.it做的是形式主语,逻辑主语为 that you should not tell other people the password of your email account.要是选A的话What is required句子做的是真实主语,后面的结构应该是in the regulation IS that you should not tell other people the password of your email account.显然这道题当中并无is,所有只有C符合答案~!

选C
翻译：守则要求不要告诉别人你的电子邮箱账户的密码。
是It is that形式的定语从句。
选A的话要在that you should……之前加is，否则句子缺少谓语动词。

c,按规定要求，你不得告诉其他人你的电子邮箱帐户密码

C呗！
