题目内容
11.我们镇上没有人知道这台机器人他买了多久.No one in our town knowshow long he has had the robot.
分析 how long he has had the robot.
解答 答案:how long he has had the robot.作为know的宾语从句,how long多久,作为引导词,后加陈述语序,主句是一般现在时,从句时态不受限制,表示买buy发生在过去,持续了一段时间,故用现在完成时have/has+过去分词,buy短暂性动词不能与how long连用,故换成have,主语he故has,have过去分词had,故答案是how long he has had the robot.
点评 本题旨在考查宾语从句这一语法,做这类题时,要从三方面考虑:一、选准连接词 二、连接词后紧跟从句的主语 三、若主句是过去时,从句要改为相对应的过去时
