1.楼主看错答案了吧,正确答案是C,而不是B.
It is/was essential that从句 这个固定句型中,要求that从句必须使用虚拟语气,即从句谓语由“should do sth”构成,且should可以省略.
即 C be sent = should be sent
2.B
根据句意可知,它是对过去动作的虚拟.
根据语法规定,if从句使用过去完成时,而主句谓语使用would/could/might have done sth结构.
过去完成时的否定形式即为:hadn't done sth
3.D
同样,固定句型it's decided that从句中,that从句使用虚拟语气,即从句谓语由should do sth构成,should可以省略.
D should not be allowed 还可以写成:not be allowed
