Question

—We have no idea ________.    
—It’s heard that he is Mr. Green’s son.

A．where he comes from	B．if does he live here
C．who he is	D．who is he

Answer 1

C

试题分析：— 我们不知道他是谁。 — 据说他是格林先生的儿子。A. where he comes from他来自哪里；B. if does he live here，他是否在这里住。这里if引导的从句应该用陈述语序，所以排除B；C. who he is他是谁；是陈述语序；D. who is he他是谁；是疑问句语序；根据答语可知问故选，用who提问；这里放在have no idea后是idea的同位语从句，应该用陈述语序。所以用who he is。故选C。
