17.-When did you buy the computer?
-I have ______ this computer for 5years,but it still works well.(  )
A.boughtB.haveC.had

分析 --你什么时间买的这台电脑?
--我已经买了5年了,但是它的性能仍然良好.

解答 答案C  buy意为"买",是非延续动词,不能和一段时间连用.have意为"拥有",是延续性单词,可以和一段时间连用.根据时间状语"for 5years"说明电脑是五年前买的,一直到现在还拥有这台电脑,所以要用现在完成时,所以要用have的过去分词had.故选C.

点评 首先要掌握哪些动词是延续性单词,哪些动词是非延续动词,再结合时间状语,选择相应的动词.
