19) ____ mainly for the invention of the telephone,Alexander Graham Bell devoted his life to helping the deaf.
A) He is remembered B) While being remembered
C) To be remembered D) Though remembered
为什么选D
答
用排除法,如果选A,前半部分是完整的句子后半部分也是完整的句子,中间没有连接词,不对
选B 语法不对,被动语态省略,be部分一起省略,要不就用完整的句子
选C To be remembered 表将来,不和题意
所以选D 被动语态省略形式的用法,如果主语是一致的,省略主语,be部分也一起省略,只要连接词和分词,这句话的意思是,尽管贝尔因为电话发明被众人所记,但他倾其一生都在为失聪者服务.
