语法精讲The -ing Form(3)—Used as Adverbial 动词ing形式（3）—作状语 1.动词ing形式作状语，表示时间、原因、结果、条件、让步、方式、伴随等，其逻辑主语必须与句子的主语保持一致，必须与句子的主语有逻辑上的主谓关系，且分词表示的动作是次要动作。 Hearing the news,he got excited.(表时间) Be careful when crossing the street.（表时间） Father died,leaving us nothing.（表结果） Being ill,she went home.（表原因） 2.若分词的动作发生在谓语动词以前，则分词使用完成式：having done。 Having finished his homework,he went home. Having been bitten by a snake,she was frightened at it. 3.动词ing形式的否定形式，在动词ing之前加not。 Not having received his reply,I rang him again. 4.有些动词ing形式，在句中作状语，不受上下文的影响，称作独立成分。 Generally speaking,he can arrive on time. Judging from his looks,he is honest. Considering what he said,he told a lie. 5.如分词的逻辑主语不再是句子的主语，而是另有一个，且直接放在了分词的前面，这就是独立主格结构，在句中同样可作状语。 |
