题目内容
11.I found them ______ at a table,_______ in thought.( )A. | seated; losing | B. | seated; lost | ||
C. | seating; losing | D. | seating; lost |
分析 我发现他们坐在桌旁陷入沉思中.
解答 答案:B 句中found后接复合宾语,即find sb done;seat与them之间构成动宾关系,要用表示被动的过去分词;be lost in thought陷入沉思.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.
