5、udy. 尽管被许多人嘲笑，他还是继续他的研究。 表方式或伴随情况。过去分词作方式状语或表示伴随情况，用来说明动作发生的背景或情况。一般情况下，分词所表示的动作和谓语动词所表示的动作同时发生，它可在句首、句末，间或在句中。 Seated at the table, my father and I were talking about my job. 我和父亲坐在桌子旁边讨论着我的工作问题。The old man,deeply moved, thanked the boys again and again. 老人被深深地感动了，一遍又一遍地感谢孩子们。 注意：在使用过去分词作状语时要特别注意过去

6、分词的逻辑主语一定是句子的主语，其逻辑主语与过去分词的关系是被动关系。下面的例子就可以说明这个问题。同样conj+非谓语动词单独使用时，非谓动词的逻辑主语与句子的主语须相一致。If given enough time, we finished the work.If (we are) given enough time, Hearing the sad news, tears came down to the girls eyes. 正：When she heard the news,_from the top of the building, the school looks beautif
