题目内容
11.Have you heard of it?Firefighters rushed into a burning house,three of them unfortunately in and their lives.( )A. | catching; lost | B. | caught; lost | ||
C. | caught; losing | D. | catching; losing |
分析 你听说了吗?消防员冲进着火的房子里,其中三人被困,牺牲了.
解答 答案:C
题干中three of them与动词catch in之间是被动关系,要用过去分词;与lose之间是主动关系,要用现在分词.故选C.
点评 过去分词是非谓语动词的一种,用法很灵活,分为简单式done(表示与谓语同时或几乎同时发生的动作);完成式having been done(表示先于谓语的动作).学习时,要把握其用法特征:表示被动和完成.同时还要注意区分现在分词和不定式.
