The building at the street corner is the hospital _____ last year.

Question

A. where I stayed B. Which I stayed on
C. that I stayed D. what I stayed

选哪个，为何？

Answer 1

A 定语从句如果不少主语，宾语，表语成分， 则要用关系副词
I stayed last year 并不缺少以上成分， 所以用关系副词where
B答案把on改成in也可以

Answer 2

选A.考察定语从句。where I stayed 作定语，修饰the school. stay 是不及物动词，不需要宾语。所以用关系副词。而school 是地点名词，对应的副词是where.所以选择where I stayed.
