题目内容
12.________ to Anne's birthday party,Mr.Brown is now searching shop after shop for a nice present for her.( )A. | Having invited | B. | Having been invited | ||
C. | Have been invited | D. | Being invited |
分析 受邀参加Anne的生日聚会,布朗先生现在正在一家店一家店地给她挑选礼物.
解答 答案:B
句中有逗号分隔,没有连词,要用非谓语动词;invite与主语Brown构成动宾关系,要用表示被动的过去分词;句意表达的invite动作发生在search动作之前,要用分词的完成式作原因状语.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.
