怎么区别after作连词还是介词比如Tears came to his eyes( )A.after hearing the newsB.after he heard the news
应该选B!
在这题中,考点是"用非谓语动词做状语的前提是,非谓语动词的逻辑主语要和主句的主语一致!"
本题中,主句的主语是tears,而tears 是不可能做hearing 的逻辑主语的,因为tears 是不可能做hear 这个词的主语的,"眼泪是不可能听的",而"能听的"只能是"人".主句的主语和非谓语动词的逻辑主语不一致,所以不能直接使用非谓语,必须用从句的方式,将另一个主语讲清楚,所以B选项里的AFTER是连词,而不是介词
