having done 表示主動完成,作狀語多,作賓語也有,但少見
Having reviewed my lessons,I go to bed. 我復習完...所以主動完成
to have done 表示過去,主要是要學會區(qū)分to do
I am sorry to keep you waiting,to keep 說明你還沒讓他等,先提前打招呼
I am sorry to have kept you waitingto have kept 說明過去讓他等了,現在說對不起
還有有的動詞后面跟doing的,有的跟to do的比如說deny doing,那么就deny having done,不能說deny to have done
seem to do,那么就seem to have done,不能說seem having done以上兩個是作賓語的情況,但是having done做賓語的情況不多,to have done蠻常見的
