问题补充:
Nowadays people are more concerned about the environment they live.
A. what
B. which
C. when
D. where
答案:
A. what
B. which
C. when
(答案→)D. where
解析:句意:如今,人们更加担忧他们生活的环境。该复合句包含一个定语从句,其先行词为the environment,且关系词在从句中作live的地点状语,故用关系副词where。而which为关系代词,在定语从句中作主语或者宾语;when为关系副词,需在定语从句中作时间状语。定语从句中关系词无what。
【考点定位】考察定语从句关系词用法。
