()the letter ,i went out to post it.A.writing B.having written C.to write D.written

()the letter ,i went out to post it.A.writing B.having written C.to write D.written
b 这里前半句表示时间状语用having表示已完成并且作为非谓语因为句中已经有谓语went 了
所以去掉 d
并且要表示在 went out 发生之前所以选b 排除A C

B. having written

答案选B.having written为什么呀？根据一致原则状语从句的主语只有和主句一致的时候，才能省略。由he went out to post it（主句）可以知道he 是主语，所以与letter是主动关系排除a,d 又因为状语从句中主句用过去式，从句用现在完成时。所以c。a选项怎么表示被动关系呀？还有现在完成时应该是have done啊？怎么是having done？...
