这题为什么用过去进行时?
完形填空:
The Taj Mahal ______(build) in the seventeenth century for the emperor Shah Jehan.我填的是built 而答案是was built 这是被动语态吗?
The Taj Manal which ______(begin) in 1632 and ______(complete) in 1654 ______(cost) a fortune.我填的是 began;completed;cost 而答案是was begun;(was) completed;cost 为什么用过去进行时而不用过去式?
被动语态的构成是:be+过去分词
但begin的过去分词是began啊!
