Question

英语选择,
It is essential that these application forms _______ back as early as possible.
A) must be sent B) will be sent C) are sent D) be sent

Answer 1

It is essential that sth.should +动词原形,
是虚拟语气,这边省略了should
例如It is demanded / necessary / a pity + that…结构中的主语从句的谓语动词要用should 加动词原形,should 可省略.
所以选 D
