题目内容
18.从小时候起,我就一直梦想着当一名医生.Ever since I was a child,Ihave dreamed about becoming a doctor..
分析 从小时候起,我就一直梦想着当一名医生.
解答 答案:have dreamed about becoming a doctor.
根据状语从句Ever since I was a child可知主句的谓语动词用现在完成时态.表示"从小时候起,我就一直梦想着当一名医生."
点评 考查现在完成时态.
现在完成时态由"have/has+过去分词"构成,主要有两个含义:①表示动作发生在过去,但与现在的情况有联系,有时无时间状语,有时和一些表示不确定的过去时间状语连用,如:many times,just,yet,ever,never,already,before,so far,by now等连用. ②表示从过去某一时间开始一直延续到现在并还可能继续延续下去的动作,用于延续性动词,且句中常带有表示一段时间的时间状语,如:for two months,so far等.
