the good news, they went wild with joy.(When they heard the good news, they went wild with joy.) 听到这个好消息，他们高兴得发了狂。原因Getting up late, he missed the early train.(Because he got up late, he missed the early train.)由于起床晚了，他没有赶上早班火车。条件Turning to the left, you will find the school.(If you turn to the left, you will find the school.) 向左拐，你就会发现那所学校。让步Knowing where I live, he never comes to see me.(Although he knows where I live, he never comes to see me.) 尽管知道我住哪里，但他从来也没有来看我。结果The boy fell off his bike, breaking his left arm.(The boy fell off his bike so that he broke his left

tired, he couldnt walk any further.Although he worked as hard as he could, he didnt pass the exam.Working as hard as he could, he didnt pass the exam.二、动词ing形式的时态和语态1在逻辑上，当动词ing形式表示的动作和句子谓语动词表示的动作(几乎)同时发生时用一般式；当动词ing形式表示的动作发生在句子谓语动词之前时用完成式。 Seeing the stranger coming towards him, little Tom ran away as fast as he could.看见陌生人朝他走来，小汤姆尽可能快地跑开了。( see和run几乎同时发生)Having studied English for three years, he could read brief stories in English.由于学习了三年英语，他能用英语读简单的故事。(study发生在read之前)2在逻辑上，当句子的主语执行动词ing形式表示的动作时，动词ing形式用主动式；当句子的主语承受动词ing形式表示的动作时，动词ing形式用被动式。 He listened to the tape, making notes now and then.他听着磁带，偶尔记笔记。(he执行make表示的动作)Being called by a stranger, he realized what had happened. 由于一个陌生人打电话，他意识到出事了。(he承受call表示的动作) 即时训练2用动词ing形式完成句子Having written an important letter(写完一封重要的信后), I listened

though/although等。“从属连词动词ing形式”可以视为状语从句的省略。Dont talk while having dinner (while you are having dinner)吃饭时不要说话。Though working hard(Though he worked hard), he couldnt earn enough money to pay off his debt.尽管努力工作，他也不能挣到足够的钱还清债务。2动词ing形式的否定形式是在其前加not或never。She was puzzled, not knowing what had happened.她迷惑了，不知道发生了什么。Not having tried his best, he failed in the exam.由于没有尽最大努力，他这次考试没通过。3动词ing形式与不定式作结果状语时的比较动词ing形式作结果状语，表示自然而然的结果。而不定式作结果状语则表示出乎意料的结果，且常与only 连用。He ran all the way, reaching the school out of breath.他跑了一路，到达学校时上气不接下气。Yesterday I went to see him, only to learn that he had gone abroad two days ago.昨天我去看他，结果了解到他两天前已经去了国外。4动词ing形式与独立主格结构作状语时的比较动词ing形式作状语时，其逻辑主语要与主句的主语相一致，如果不一致，通常要在动词ing形式前加上它自己的逻辑主语，这种带逻辑主语的动词ing形式被称为独立主格结构。Arriving at the station, he found the train had left.到达车站时，他发现火车已经开走了。(he是arriving的逻辑主语)She walked along the path, her daughter following close behind.她沿着小路走，其女儿跟在后面。(following的逻辑主语是her daughter，而不是句子的主语she)5有少数动词ing形式并不表示句子主语的动作，而是表示说话人的态度，被称作独立成分，它不受句子主语的限制。常见的有：generally speaking一般来说；judging from/by根据来判断；considering考虑到，鉴于；supposing假设等。Generally speaking, the more you practise, the more skillfully you can write in English.一般来说，你练习越多，用英语写作就越熟练。即时训练3用动词ing形式完成句子Although working hard from morning till night(虽然从早到晚拼命干), his father didnt get enough food.Not knowing how to deal
