题目内容
15.-Ah,Anita.Is the design for the conference center ready?-I _____ on it for over a month,but I haven't finished it yet.( )
A. | worked | B. | had worked | ||
C. | have been working | D. | was working |
分析 --啊哈,Anita.会议中心的设计好了吗?
--我已经专注于这项工作一个多月,但是还没有完成.
解答 答案是C.本题考查现在完成进行时.由问句中的动词时态判断询问的是"现在的情况",所以排除A、B和D;现在完成进行时表示表示从过去某时开始到现在这一段时间里一直延续着的动作还在继续进行;根据答句中的"I haven't finished it yet."可知,设计还在进行中,故选C.
点评 完成进行时的解题首先要理解其时态的基本用法--表示从过去某时开始到现在这一段时间里一直延续着的动作,特别关注其"在进行中"的特征;然后在语境中寻找动作的时间依据进行判断.
