_____a reply,he decided to write a sixth letter.
A.Not receiving B.Not to receive
C.Not having received D.Having not received
是C还是D,为什么
A.Not receiving B.Not to receive
C.Not having received D.Having not received
是C还是D,为什么
C~根据后面的过去时，前面就是完成时。ing形式的从句。not提前！
C 动名词的否定式,not应该放在前面
应该是D吧，not要放在have和done之间，而且C读起来很别扭啊
当然是D.
你可以试把not去掉，意思刚好相反。
然后再把having received变成have received.
have received 的反意是have not received. not have received,语法不通。
再变，having not received.这就可以了。
