问题补充:
He suggested the person referred put into prison.
A. is
B. be
C. should be
D. to be
答案:
A. is
B. be
C. should be
(答案→)D. to be
解析:考查词组和虚拟语气:主句的谓语是 suggest宾语从句用虚拟语气: that sb. should do sth. 其中that 和should 可以省略。句子中referred to 是过去分词作定语,修饰the person ,be put into prison是宾语从句的谓语部分,省略了should,句意:他建议被提到的人被送进监狱。选D。
