in the regulations is that you other people the password of your e-mail account.
A. What is required; not tell
B. As is required; shouldn’t tell
C. It is required; not tell
D. It requires; shouldn’t tell

(答案→)A. What is required; not tell B. As is required; shouldn’t tell C. It is required; not tell D. It requires; shouldn’t tell解析：考查主语从句和虚拟语气。本题第一空是what所引导的主语从句what is required in the regulation，what在句中做主语。因为第一空中有动词require，后面的从句要使用“should+动词原形”构成的虚拟语气，should可以省略。句意：在规则中北要求的是你不应该告诉别人你的邮箱的密码。故A正确。
