题目内容
8.______to change his plans,Mark Twain worked for several years as a pilot on the steamboat.( )A. | Force | B. | Forcing | C. | Forced | D. | To force |
分析 被迫改变计划,马克吐温在蒸汽船上当了几年引航员.
解答 答案:C
句中有逗号分隔,没有连词,要用非谓语动词;force与主语Mark Twain构成动宾关系,要用被动.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.
