Whilewalkinginthegarden,hehurthisleg.在花园里散步时他伤了腿。
分词作时间状语,如果先与主动词的动作,且强调先后,要用havingdone。
Havingfinishedhishomework,hewentout.
=Ashehadfinishedhishomework,hewentout.
___areply,hedecidedtowriteagain.
A.NotreceivingB.ReceivingnotC.NothavingreceivedD.Havingnotreceived
答案C.本题考查分词的时态与分词的否定式。根据题意判断,分词的动作(接信)发生在谓语动词的动作(决心再写信)之前,因此用分词的完成式。分词的否定式的构成为not+分词,故选C。该句可理解为:Becausehehadnotreceivedareply,hedecidedtowriteagain.
