He was often seen _________ with charity work last year.
A．to helpB．helpedC．helpingD．help
A

試題分析：see后面賓語可以接現(xiàn)在分詞,不帶to的不定式和過去分詞作賓語補足語,不過含義不同. see sb. doing 表示看見某人正在做某事;see sb. do 表示看見某人做過某事;see sb. done 表示看見某人被…句意:去年(有人)經(jīng)�？匆娝麕椭壬茍F體工作.結合語境可知本句指的是看見他做過某事.在被動語態(tài)中,省略的不定式符號要加上,故選A.
點評：此類題型主要是確定句子主語與謂語動詞的關系。如果是主動關系則用主動語態(tài)，反之如果是動賓關系，則用被動語態(tài)。注意一些接不帶to的不定式做賓語補足語的動詞用作被動語態(tài)時，不定式符號to要加上。
