20.我想知道会议是否开始近10分钟了.
I wonder whether the meeting has been on for almost ten minutes or not..

分析 I wonder whether the meeting has been on for almost ten minutes or not.

解答 答案:I wonder whether the meeting has been on for almost ten minutes or not.这里是宾语从句,主句是我想知道用一般现在时,I wonder,从句的时态不受限制,引导词是wherther是否,末尾加上or not,这里是说会议是否开始近10分钟了.开始这个动作发生在过去,持续到现在用现在完成时have/has+过去分词,主语是the meeting 单数,故用has,这里是说开始了近十分钟用时间状语for almost ten minutes 一段时间,此时的动词不能用短暂性的动词begin,而用be on表状态,be的过去分词是been,故答案是I wonder whether the meeting has been on for almost ten minutes or not.

点评 这里是宾语从句的呈现,时态语序连接词我们一一考虑,这里要注意现在完成时中需要用延续性动词和一段时间连用.
