Question

He lives in a room _______ faces the south.

A．whose windows	B．the window of which
C．whose the window	D．of which the windows

Answer 1

B

试题分析：考查定语从句，先行词是a room，句意：他住在面朝南的房子里面。定语从句可以用whose windows或the window of which及 of which the windows，但因为定语从句的谓语是faces，所以window是单数。选B。
点评：定语从句的考查主要集中在句子成分的分析。如果从句中缺少主语，宾语，表语定语使用关系动词。如果从句很完整，则使用关系副词。如果缺少定语，用whose引导定语从句，或是of which the+名词/the+名词+of which。
