it還是he

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

此題應(yīng)選C。第a. 句填代詞 he，是因為前面一句用了Jim這一身份和性別都很明確的名詞；第b. 句填代詞it，是因為前面一句了someone這一指代不明確的代詞。

一般說來, 在指代身份或性別明確的人時, 通常要根據(jù)情況用代詞he/she；若是指代身份或性別不明的人, 則用代詞it：

I don’t know who it is. 我不知道那是誰。
