问题
A series of attempts______made, he came to a successful solution of the problem.
选项
A、to be
B、had been
C、were
D、having been
答案
D
解析
该题考查独立主格结构的用法,有一定的难度。make attempts to意思是"尝试着做某事"。结合后半句的时态我们可以推知前半句的时态应当是过去完成时,同时从句中a series of attempts充当逻辑主语,故需采用被动语态。综上分析,选项D为正确答案。译文:经过了一系列的尝试之后,他终于成功地找到了解决这个问题的方法。
