问题： ____a reply, he decided to write again.

选项：

A. Not receiving

B. Receiving not

C. Not having received

D. Having not received

答案：C

解析：

本题考查非谓语动词。receive和其逻辑主语he，是”他收到“，是主动关系，故用现在分词，但主句中的again又暗示分词的动作发生在句子谓语动词之前，因此用现在分词的完成式。not必须置于分词之前，因此选C。前半句可以理解为：As/Since he hadn't received a reply, he decided to write again。本句句意为：没收到回复，他因此决定再写一封。
