题目内容
【题目】With many cities in China dreadfully blanketed by thick haze, the environment problem is _____ Chinese people concern most nowadays.
A. what B. which
C. where D. when
【答案】A
【解析】句意:由于中国许多城市都被可怕的雾霾覆盖,环境问题是现在这中国人关注最多的问题。表语从句中缺少concern的宾语,能够在表语从句中做主语或宾语的用what。which在引导表语从句是作定语,如:The problem is which side we should take问题是我们应该站在哪一边。where在表语从句中作地点状语;when在表语从句中作时间状语。故判断选A。
