问题补充：
---- I’m sorry .I your printer for such a long time.
---- Never mind.
A. have borrowed
B. have lent
C. have kept
D. have bought
答案：
A. have borrowed
B. have lent
(答案→)C. have kept
D. have bought
解析：borrow借入；lend借出；keep 保持，持有；buy买。句意：抱歉，我拿着你的打印机这么久了。——不必介意。英语瞬间动词不能和表示一段时间的时间状语连用，borrow，lend和buy表示瞬间动作，故选C。
