题目内容
1.________ several times,the young scientist still kept on doing his experiments.( )A. | Failed | B. | Having been failed | ||
C. | Having failed | D. | To fail |
分析 在经历了几次失败后,这名年轻的科学家仍然坚持做实验.
解答 答案是C.本题考查现在分词完成式;题干中需要的是非谓语动词做时间状语,主语the young scientist 和fail之间的主动关系,用现在分词,排除A和B;动词不定式表示将来,本题中动作已经发生,排除D;现在分词完成式表示分词的动作在谓语动词之前已经发生或完成;根据语境,"先失败",然后才有"继续坚持",故用现在分词完成式,答案是C.
点评 首先判断选项中的动词在句中是以谓语还是非谓语形式出现,然后根据选项在句中的功能结合非谓语的基本用法做出合理的判断.要关注常见非谓语动词的搭配.
