Question

I          this book for two weeks. I have to return it now.

A．borrowed

B．have borrowed

C．kept

D．have kept

Answer 1

D

试题分析：句意：这本书我已经借了两周了，现在我必须归还它。borrow是非延续性动词，用于现在完成时态时不能和时间段连用。可用延续性动词keep代替borrow。
点评：非延续性动词向延续性动词的转变熟记一下几个：
leave --- be away,  borrow --- keep,   buy --- have,  begin/start --- be on,      die --- be dead, leave --- be away from, fall asleep --- be asleep
