题目内容
20.On flight would be delayed,we made other arrangements.( )A. | being informed | B. | informed | C. | informing | D. | having informed |
分析 我们一知道航班延误了,就做了其它安排.
解答 答案:B 句中有逗号分隔,没有连词,要用非谓语动词;inform与主语we之间构成动宾关系,且句意表达的是事实,要用过去分词形式.故选B.
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.
