____ an answer,I decided to write him again.

题目
____ an answer,I decided to write him again.
A.Not to have received
B.Not being received
C.Having not received
D.Not having received
答案
not having done是非谓语动词中正确的用法,用作状语比较多,如
Not having heard from him,she decided to write another letter
have not done 是谓语动词完成时的否定形式,一般没有having not done
所以排除C
此句前后是主动关系主语都是I 所以排除B
根据时态来说 我是在没有接到回复之后再写信故用完成时态 所以排除A
综上,此题答案为D
如果还有哪里不清楚我愿意继续解答
