        1. ---What a nice MP3! How long ______ you ______ it?  ---Only two days.

          A.have, bought B.did, buy
          C.have, had D.a(chǎn)re, having

          C

          解析試題分析:句意:多么好的一個MP3。你買這個多久了?僅僅兩天。現(xiàn)在完成時可以用來表示發(fā)生在過去某一時刻的,持續(xù)到現(xiàn)在的動作(用行為動詞表示)或狀態(tài)(be動詞表示)常與for(+時間段),since(+時間點(diǎn)或過去時的句子)連用. 現(xiàn)在完成時中,非延續(xù)性動詞不能與for和since引導(dǎo)的表示一段時間的狀語連用,通常是用相應(yīng)的延續(xù)性動詞來代替。buy 對應(yīng)的延續(xù)性狀態(tài)詞是have。故選C
          考點(diǎn):考查現(xiàn)在完成時態(tài)的用法。
