~~Who broke the window ? ~~Jack____
A was
B does
C did
D had
~~Who broke the window ? ~~Jack____
A was
B does
C did
D had
选C.
首先确定用过去式,因为前面有broke,则排除B项。
另外broke是实义动词,回答不能用be动词,则排除A项。
而D项,如果补充完整为Jack had broken the window,时态不对,不是过去完成时,没有过去参照的时间。
故选C项,符合题意,补充完整为Jack broke the window.
选C,这是一个省略的回答,完整的应是:Jack broke the window.这里的did代指broke the window.
望采纳
