现在分词作状语时，表示的动作是主语动作的一部分，用来修饰谓语，常表示动作发生的时间、原因、条件、结果、方式、伴随、让步等情况，并可以转换成相应的状语从句或并列句。 二、规则 动词 形式 意义 以do为例 一般式 (not) doing 主动式 (not)doing 与句子主语构成逻辑上的主谓关系，与谓语动作同时发生，或基本上同时发生 被动式 (not)being done 与句子主语构成逻辑上的动宾关系，且与谓语动作同时发生 以do为例 完成式 (not) having done 主动式(not) having done 与句子主语构成逻辑上的主谓关系，先于谓语动作发生 被动式(not) Having been done 与句子主语构成逻辑上的动宾关系，且先于谓语动作发生 (一)现在分词作状语的用法 现在分词(短语)在句中作状语来修饰谓语动词或整个句子，表示动作发生的时间、原因、条件、结果、方式、让步或伴随状况。 1．作时间状语 现在分词作时间状语时，常放在句首，相当于一个时间状语从句。 *Hearing the noise, I turned round. ＝When I heard the noise, I turned round. 听到响声我转过身去。 2．作原因状语 现在分词作原因状语时，相当于一个原因状语从句，也可以放在句首。 *Having lived in the village for years, I know everyone quite well. ＝Because I have lived in the village for years, I know everyone quite well. 因为在这个村里住了很多年，所以我熟悉每个人。 3．作条件状语 现在分词作条件状语时，相当于一个if引导的条件状语从句。 *Working hard, you'll certainly succeed. ＝If you work hard, you'll certainly succeed. 只要努力学习，你肯定会成功的。 4．作结果状语 现在分词作结果状语时，通常放在句末，中间用逗号隔开，表示自然而然、意料之中的结果，分词前可接thus。 *More highways have been built in China, making it much easier for people to travel from one place to another. 中国建了很多高速公路，这使人们从一个地方到另一个地方变得更容易了。 ◆[微点拨] 现在分词作结果状语，是随着谓语动词的发生而产生的自然结果，其逻辑主语往往是前面整个句子所描述的情况，前面有时候可以加thus。而不定式作结果状语常表示出乎意料的结果，有时候前面可以加only。 5．作让步、方式和伴随状语 现在分词作让步、方式和伴随状语时，说明动作发生的背景和情况。作伴随状语时，表示分词的动作和主句的动作同时发生，此时它可转换成并列句。 *Mary sat by the window of the classroom, reading a book. ＝Mary sat by the window of the classroom and read a book. 玛丽坐在教室的窗边读一本书。 (二)现在分词作状语的注意事项 1．现在分词的时态 现在分词作状语时，要注意分词的时态，是用现在分词的一般式(doing)，还是用完成式(having done)。 当现在分词的动作与谓语动词的动作同时发生时，用分词的一般式；当现在分词的动作发生在谓语动词的动作之前时，用分词的完成式。 *Walking in the street, I met an old friend of mine. 我正在大街上行走时，遇到了一位老朋友。(walking和谓语动词met同时发生) *Having finished the letter, he went to post it. 他写完信后就把它寄了出去。(having finished 是先发生的，went是后发生的) 2．现在分词的语态 使用现在分词的主动式还是被动式，这主要取决于现在分词和句子主语之间的关系。句子的主语就是分词的逻辑主语。 *Having been shown around the factory, they were very happy. 被领着参观了工厂后，他们很高兴。(现在分词的被动式) *Having finished his homework, he went to bed. 完成了作业后，他上床睡觉。(现在分词的主动式) 3．现在分词作状语时，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多时间，解释她为什么不想让孩子们在一起玩。(explaining是句子主语My wife做出的动作，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. 火车已经离开了，我们只好再等一天。 (The train having gone为独立主格结构) 4．现在分词的否定式是在分词短语前面加上not, never等否定词。 *Not knowing how to find the subway, I asked a policeman for help. 我不知道怎样找到地铁，就去找警察帮忙。 5．现在分词作评注性状语 有些现在分词在句中没有逻辑主语，它们往往作为句子的评注性状语来修饰整个句子，表明说话者的态度、观点等。如：generally speaking一般来说，judging by/from从……判断，speaking of说到……，talking of谈到……，frankly speaking坦白地说，considering.../taking... into consideration考虑到……，providing...如果……，supposing...假如……等。 *Judging from his behaviour, he must be mad. 从他的行为来判断，他一定是疯了。 *Taking the weather into consideration, we put off the sports meeting. 考虑到天气情况，我们推迟了运动会。 ◆[针对训练] Ⅰ.完成句子 1．　Standing on the top of the mountain　， I could see the whole city.＝When I stood on the top of the mountain, I could see the whole city. 站在山顶上，我能看到整个城市。 2．　Hearing the noise　， I turned round.＝When I heard the noise, I turned round. 听到响声我转过身去。 3．　Being too young　， he couldn't join the army.＝ Because he was too young, he couldn't join the army. 因为太年轻，所以他不能参军。 4．　Working hard　， you'll succeed. ＝ If you work hard, you'll succeed. 如果努力工作，你就会成功的。 5．　Admitting what she said　， I still think that she hasn't tried her best.＝ Although/Though I admit what she said, I still think that she hasn't tried her best. 尽管承认她所说的话，但我仍然认为她没有尽最大的努力。 6．He walked down the river, 　singing softly to himself　.＝ He walked down the river and sang softly to himself. 他沿着河流一边走，一边轻轻地哼着歌。 7．His parents died in the war, 　leaving him an orphan　.＝ His parents died in the war so that he was orphaned. 他的父母在战争中死了，以致他成了孤儿。 8．　Not seeing John　， I asked where he was＝As I

mistake. 虽然被告诉过好多次了，但杰克仍然重复犯同样的错误。 Ⅱ.语法填空 1．　Tasting　 (taste) sweet, this kind of apples was soon sold out at a high price. 2．John watched curiously, 　thinking　 (think) that the woman seemed a little
