这句话我看不懂结构 不知道哪里是定语从句 哪里是先行词
27.With the development of agriculture,the people _____ village I taught before have lived a happy life.
A.who \x05B.whose \x05\x05 C.in whose D.in which
选什么 哪个是先行词 定语从句在哪边 修饰什么?谁帮我分析一下句子结构 这句话怎么拆成单句呢
谁能说得再清楚一点呢

答案

选C.
With the development of agriculture是状语,可以暂时忽略.
在the people in which village I taught before have lived a happy life.中
主句是the people have lived a happy life.
从句是I taught in the people's villiage.
先行词为the people,既然是先行词了,当然就是修饰它的了.
villiage 和 people有从属关系,用whose而不用which
同时状语in不能省.
综上,C.
