Question

【题目】On the second floor there are two rooms，________is used as a meeting room.

A．the larger of which

B．one of them

C．the larger one of that

D．the largest of which

Answer 1

【答案】A。

【解析】句意：在二楼有两个房间，其中较大的那个被用作会议室。句中没有连接词，可知逗号后为定语从句，the larger of which＝and the larger of them＝and the larger of the two rooms。B项变为and one of them才正确；定语从句中，若介词置于引导词前，则不能用that而用which，所以C项也不正确。
