题目内容
19.I won't go to his birthday party unless tomorrow.( )A. | inviting | B. | being invited | C. | invited | D. | invitation |
分析 除非受到邀请,否则我不会参加他明天的生日聚会.
解答 答案:C
句中unless连接条件状语从句;从句中省略了相同的主语和系动词,即unless I am invited,是被动语态,要用过去分词来构成.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.
