---I am sorry to have kept you ___________.
---It doesn"t matter. I"ve just come.

A．wait

B．waited

C．waiting

D．to wait

答案

解析

试题分析：句意：非常抱歉让你久等了。没关系，我刚刚来。keep 后接双宾语keep sb doing让某人一直做某事，故选C.
点评：keep sb/sth doing（使某人/某物处于一种持续的动作）；keep+adj 这种结构是“主语”保持某种不变/持续的状态；keep +双宾语如果宾语和宾语补足语之间是主动关系用doing的形式，如果是被动关系用done的形式。
