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

試題分析：句意：這本書我已經(jīng)借了兩周了，現(xiàn)在我必須歸還它。borrow是非延續(xù)性動詞，用于現(xiàn)在完成時態(tài)時不能和時間段連用。可用延續(xù)性動詞keep代替borrow。
點評：非延續(xù)性動詞向延續(xù)性動詞的轉(zhuǎn)變熟記一下幾個：
leave --- be away,  borrow --- keep,   buy --- have,  begin/start --- be on,      die --- be dead, leave --- be away from, fall asleep --- be asleep
