《高中英语》 选修(模块）6-5.1 Period 4 grammar Review the usage of –ing form. Examine the sentences beloew and discuss in what way the structures similar to each other and in what way they are different Looking carefully at the ground, I made my way to the edge of the crater. The –ing form used as an adverbial Having experienced quite a few earthquakes in Hawaii already, I didn’t take much notice. Having + past participle (the perfect –ing form) to refer to an action that took place before the time expressed by main verb. 小结-ing 形式的用法 1. –ing 形式作状语 用法 例句 时间 Walking along the street, I met Mary. (= While I was walking along the street….)在街上走的时候，我遇到了玛丽。 原因 Being tired , I stopped to take a rest. (= Because I was tired, ….)因为疲倦，我停下来休息。 条件 Turning to the left, you will find the schoo. (= If you turn to the left, ….)向左走，你就会找到那个学校 让步 Knowing where I live, he never come to see me .(= Though he knows where I live, ….)尽管他知道我的住处，但从不来看我。 伴随 I stood there, waiting for her. (= …, and waited for her.)我站在那儿等她。 结果 It rained heavily, causing severe flooding in the area.(= It rained heavily so that it caused severe flooding in the area.)在这个地方雨下的如此大，以至引发了洪灾。 2. –ing形式的完成式 句型 主动 Having +p.p. …, 主语+谓语 被动 (Having been)+p.p. …, 主语+谓语 用法 –ing形式的完成式所表示的时间在谓语动词之前 表示被动可直接用过却分词 例句 Having finished my work, I went home. (= After I had finished my work, ….)工作做完只后，我就回家了。 例句 (Having been) written in haste, the book has some faults. 这本书因仓促写成，所以有些缺憾。 3. 使用-ing形式需注意的几个问题。 分词(短语)作状语时，其逻辑主语必须与 句子的主语一致。如果不一致，必须用独 立主格结构来表示，也就是在分词前面加 上它的逻辑主语。 My wife had a long talk with Sally, explaining why she didn’t want the children to play together我妻子与莎莉 谈了很长时间，解释她为什么不想让孩子 们在一起玩。(现在分词explaining是句子 主语my wife做的动作，它们之间是主动 关系,即explaining的逻辑主语，就是句子 的主语my wife 。) The train having gone,we had to wait another day.（the train逻辑主语 + having gone 既为独立主格结构） 分词短语做状语时，前面可以加上连词或 介词，但是分词短语和句子之间不能用并列连词(如but，and)，因为并列连词接的是两个并列成分，而分词短语只是全句的一个状语部分。分词和主句之间可用逗号。 例如: 误: Having been told many times，but
