特殊疑问句的助动词和系动词.
when was the house built?为什么不改成
when did the house build?
而且BUILD是实义动词啊,怎么能加系动词呢?
还有怎么决定什么时候用DO什么时候用系动词呢?
那既然是被动语态，为什么不变成when does the house was built or when the house was built?
when was the house built?为什么不改成
when did the house build?

答案
be + 过去分词 是被动语态的结构
when was the house built?
The house was built in 1997.
当主语是动作的承受者时,用被动语态加系动词
do+ 动词原形
when did the house build?是个错的.
应该是When did they build the house?
when was the house built?
The house was built in 1997.
当主语是动作的承受者时,用被动语态加系动词
do+ 动词原形
when did the house build?是个错的.
应该是When did they build the house?
