a. Jim is at the door. __________ wants to see you.

b. Someone is at the door. __________ must be Jim.

A. That,It                        B. It,He                        C. He,It                        D. Who,He

【分析】此题应选C。第a. 句填代词 he,是因为前面一句用了Jim这一身份和性别都很明确的名词;第b. 句填代词it,是因为前面一句了someone这一指代不明确的代词。

一般说来,在指代身份或性别明确的人时,通常要根据情况用代词he / she;若是指代身份或性别不明的人,则用代词it:

I don’t know who it is. 我不知道那是谁。
