动词­ing形式置于某些及物动词和宾语之后，补充说明宾语的动作或状态。在这种情况下，及物动词通常是表示感觉和心理状态的动词或使役动词。 Eric woke up a little later when he heard children playing outside. 埃里克过了一会儿就醒了，那时他听到孩子们在外面玩耍。 When we returned to the school，we found a stranger standing at the entrance. 当我们回到学校时，我们发现一个陌生人站在入口处。 1．动词­ing形式在感官动词后作宾语补足语 在see，hear，feel，watch，notice等感官动词后，用动词­ing形式构成复合宾语，表示一个正在进行的主动的动作或一种状态。 On the bank of the river，we found him sitting on a bench，with his eyes fixed on a kite in the sky. 在河岸上，我们发现他坐在长凳上，眼睛盯着天上的风筝。 Suddenly we heard someone knocking gently on the window. 我们忽然听见有人在轻轻地敲窗户。 在see，hear，feel，watch，notice等感官动词后，既可用动词­ing形式构成复合宾语，也可用省略to的不定式构成复合宾语，两者之间有一定的区别。 (1)用动词­ing形式时，表示动作正在进行。 Today on my way home，I saw a man running along the street hurriedly. 今天我在回家的路上，看到一个男人正匆忙地从街上跑过。 (2)用省略to的不定式时，表示动作发生了，即动作的全过程结束了。 All his attention was fixed on the movie，so he didn't even notice the boss enter the room. 他所有的注意力都集中在电影上，所以他甚至没有注意到老板进了房间。 2．动词­ing形式在使役动词后作宾语补足语 在keep，get，leave，have等使役动词后作宾语补足语，表示“让……一直做某事”。 It's cold.We should have the fire burning all the time. 天气冷。我们应该让火一直燃烧着。 The firm went broke and left her looking for a new job. 公司破产了，促使她一直在找新的工作。 (1)have/get＋宾语＋done，done是过去分词作宾语补足语。意为“让别人去做某事”。 He will have/get the computer repaired tomorrow. 他明天让人给他修电脑。 (2)have ＋宾语＋do sth意思是“让某人做某事”。 Mother has me go to the shop to buy some fruit. 妈妈让我去商店买一些水果。 (3)leave(使……处于某种状态)，keep(使……保持某种状态)后一般跟分词作补足语，而不跟动词不定式。 Many teachers keep parents informed of children's performance in the kindergarten by sharing videos online. 许多老师通过在线分享视频让家长知晓孩子们在幼儿园的表现。 3．动词­ing形式在with复合结构中的使用 在with复合结构中，动词­ing形式充当宾语补足语，表示动作“正在进行”。 With the College Entrance Examination drawing near，many of us feel nervous recently. 最近，随着高考的临近，我们中有很多(学生)都感到紧张。 在with的复合结构中，也可以使用过去分词(表示被动)和不定式(表示动作未发生)作宾语补足语。 He sat there with his eyes closed. 他闭目坐在那儿。 I can't go out with all these clothes to wash. 要洗这些衣服，我无法出去了。 [即时训练1]——单句语法填空

wind _________(whistle) through the trees and howl of a distant wolf. ⑥In the crowded cafe，I heard a friendly voice ______(say)，“You can share my table.” 二、动词­ing形式作状语 动词­ing形式可以作状语，在句中表示时间、原因、结果、条件、让步、行为方式或伴随等。 动词­ing形式作时间、原因、条件、让步状语时多位于句首；作结果、伴随状语时常位于句末。 I'd like to express my different voice，hoping that this wouldn't offend you. 我想表达我不同的声音，希望这不会冒犯到你。 Hearing the news，I stood there，frozen. 听到这个消息，我站在那里，僵住了。 Looking at the towering teaching building，Eva came up with a good idea，with a smile spreading across her face. 看着高耸的教学楼，伊娃想到了一个好主意，脸上绽开了笑容。 1．动词­ing形式表示时间 Seeing students study carefully online(＝When we see students study carefully online)，we all feel delighted. 看到学生们在网课期间认真学习，我们感到非常欣慰。 2．动词­ing形式表示原因 Having missed the last bus (＝As he had missed the last bus)，Wang Ming had to take a taxi home. 错过了末班车，王明只好打车回家。 3．动词­ing形式表示结果 More highways have been built in China，making it much easier for people to travel from one place to another. 中国又建了很多高速公路，这使人们从一个地方到另一个地方的出行变得更容易了。 4．动词­ing形式表示条件 Improving his skills (＝If he improves his skills)，he will easily find a job. 如果他提高了自己的技能，他很容易就能找到工作。 5．动词­ing形式表示让步 Being tired(Although they were tired)，they went on working. 尽管很累了，可他们继续工作。 6．动词­ing形式表示行为方式、伴随或补充说明 The teacher stood there，reading a newspaper. ＝The teacher stood there，and read a newspaper.(伴随，可以转化为一个并列句) 老师站在那儿，看着报纸。 The visiting minister expressed his satisfaction with the talk，adding that he had enjoyed his stay here.(补充说明) 这位来访的部长表达了对这次会谈的认可，他还补充说他此次来访很愉快。 [即时训练2]——单句语法填空 ①_____ (be)a freshman，she tended to get lost in the 6­story maze，leaving her so helpless.(2024·浙江1月卷) ②_________(throw)a quick glance at the bus station，I noticed it was now almost deserted.(2024·新课标Ⅰ卷，读后续写) ③_______ (know) that you are interested in it，I'm pleased to tell relevant information to you. ④Newly­built wooden cottages line the street，_______ (turn) the old town into a dreamland. 三、动词­ing形式作状语的注意事项 1．动词­ing形式的时态 动词­ing形式作状语时，要注意动词­ing形式的时间性，是用动词­ing形式的一般式(doing)还是用完成式(having done)。 (1) 当动词­ing形式的动作与谓语动词的动作同时发生时,用一般式。 Walking in the street，I met an old friend of mine.(walking与谓语动词met同时发生) 走在大街上时，我遇到了一位老朋友。 (2)当动词­ing形式的动作先发生，而谓语动词的动作后发生时，用完成式。 Having lived in Beijing for many years，Carter knew the city well.(having lived是先发生，knew是后发生) 因为在北京住了多年，卡特对这个城市很熟悉。 2．动词­ing形式的否定式：not＋v.­ing; not having＋v.­ed Not knowing the way，he got lost. 由于不认路，他迷路了。 Not having made full preparations，we put off the sports meeting. 因为没有作好充分的准备，我们把运动会延期了。 3．独立成分作状语 有些动词­ing形式作状语在句中没有逻辑上的主语而独立存在，其形式的选择不受上下文的影响，表明说话者的态度、观点等，被称为评论性状语。常见的有： generally speaking　一般来说 strictly speaking　严格来说 considering.../taking...into consideration　考虑到…… supposing　假设，如果 providing　如果 assuming　假使 judging from/by　根据……来判断 Basically speaking，if you put your heart and soul into learning，English is not that difficult for you. 从根本上来说，如果你全身心地投入学习中，英语对你来说就没那么难了。 Judging from her reaction，she liked the birthday present. 从她的反应来看，她喜欢这份生日礼物。 独立主格结构 有时动词­ing形式有自己的逻辑主语，这时其逻辑主语相对于句子的主语来说是独立的，因此又叫独立主格结构，其构成形式是“名词/代词＋v.­ing”。 Time permitting，we are going to visit you tomorrow. 如果时间允许，我们明天去拜访你。 All students staring at her，Mary felt uneasy. 所有的学生都盯着她看，玛丽感到不安。 [即时训练3]——单句语法填空 ①_______________ (finish) his homework，he was playing on the playground. ②__________________(warn)by
