Question

The rules require that ______you only one guest to the dinner. But they requires______

A．will bring; reforming	B．should bring; to reform
C．bring; reforming	D．have brought; to be reformed

Answer 1

D

C require用作 “要求,命令”时, 后接宾语从句, 要用should +动词原形, should可以省略; require用作“需要”时, 后接动词的-ing形式, 主动形式表示被动意义, 相当于动词不定式的被动结构。
