not receiving ,not having received a reply.He decided to write again.
在这个题里not receiving ,not having received应该选啥,
not receiving ,not having received有啥不同.

Answer 1

选择not having received.
题目意思：（因为）还没有收到回复（或者说答复、回信）,他决定再写（一封信）.这里not having received是现在分词（否定式）做状语,表示原因.由于后面说“再写一封信”,所以应当是由于“直到现在还没有收到答复”,用not receiving从语法说没有问题,但是从意思上来讲不够妥当,它只是笼通地说没有什么,或者不是正在如何,并不包含“直到现在如何”的意思.而本句的原因则需要强调直到现在还没有收到.所以应当选择not having received.
其实如果注意答题技巧,这个题目不难.你可以将现在分词还原为复合句,看哪一个更妥贴.如果还原为复合句则为：Because he have not received a reply,he decided to write again.显然十分合适.
如果选择not receiving,则应当是Because he is not receiving a reply,he decided to write again.
或者Because does not receive a reply,he decided to write again.显然都不合适
