Think about: singing, seen 和to finish的主语是谁？
注意：
非谓语动词作状语时，前面没有名词，但他 们的逻辑主语就是句子主语！→这个灰常重 要！ 如果不是句子主语，需在非谓动前加上它自 己的主语。（独立主格结构）→这个不太重 要=。=
再注意：易考到的被动表示主动的非谓语动 词作状语。
一、作用：表示时间、原因、方式、条件、 结果、目的等。 二、含义： doing：主动，进行； done：被动，完成; to do：主动，将来。 三、位置 灵活，句首、句中、句末均可。 分词作状语常搭配逗号。
1. He walked down the hill, singing gently to himself. 2. Seen from the hilltop, the river looks like a beautiful blue ribbon. 3. To finish the task in time, we have to work together day and night.
总的来说，当状语从句的主语和主句主语相 同时，可以用非谓语动词作状语，便可以 省略一个主语了。 例： 被周亮帮助，我在英语方面进步了很多。 Helped by Zhou Liang, I do much better in English learning.
Practice

三、位置： 紧挨着所修饰的名词。
