I think the photo_____by my Uncle George.A to be taken B has taken C was taken为什么不选B
问题描述：
I think the photo_____by my Uncle George.
A to be taken B has taken C was taken为什么不选B
答
主语是Photo，这里一定是被动语态，就算用完成时态，也是has been taken.A中加介词to一看就是错的
答
photo 与my uncle 是动宾关系，应该用被动呀！选C
B项没有道理，为什么要用完成时态？
答
因为 这句是被动语态
换成正常的语序应该是
I think my Uncle George took the photo.
你把它变成被动语态就是 I think the photo was taken by my Uncle George
而且照片是过去拍的,所以还是个过去式
只有照片被叔叔拍,你要是学B 就是照片拍叔叔,照片是没有那个能力的.
答
take的动作不是主语photo发出的,故用被动式,选C吧!
