when was the house built?是对的吗?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 did the house build?

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?
be + 过去分词 是被动语态的结构
do+ 动词原形
be动词和助动词do不能并存,只能有一样
被动语态
主语+be+过去分词
