动词-ing形式作状语;一、动词-ing形式的时态、语态及意义;动词;Hearing the news, they immediately set off. 听到这个消息，他们立即出发了。 Having written a letter, I listened to music for a while. 写完信后，我听了一会儿音乐。 Having been held back by the traffic jam, she couldnt get there on time. 她被交通阻塞耽搁了，无法准时到达那里。;二、动词-ing形式作状语的种类 现在分词作状语时，表示的动作是主语动作的一部分，用来修饰谓语动词，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。 ;1．表时间 Walking in the park, she saw an old friend. ＝ When she was walking in the park, she saw an old friend. 在公园散步时，她看到一个老朋友。 Having finished the work, he went out to meet his friends. ＝ After he finished the work, he went out to meet his friends. 完成工作后，他出去会朋友了。 如果强调两个动作同时发生，分词前可加when或while。;Be careful when crossing the street. 过马路时一定要小心。 Dont mention this while talking to him. 与他交谈时不要提这件事。;[考题印证1];2．表原因 Having traveled to many places, he knows a lot. ＝ Since he has traveled to many places，he knows a lot. 到过很多的地方去旅游，他知道的很多。 Being ill, he was sent to hospital. ＝ Because he was ill, he was sent to hospital. 由于生病，他被送往医院。;[考题印证2];3．表伴随或方式 He sent me an e-mail, hoping to get further information. ＝ He sent me an e-mail, and (he) hoped to get further information. 他给我发了封电子邮件，希望得到更多的消息。;[考题印证3];3－2 ________around the fire, the tourists danced with the local people. A．Gather B．To gather C．Gathering D．To be gathering 解析：选 。考查非谓语动词。句意：旅游者和当地的居民围着篝火一起跳舞。主语the tourists和动词gather 是逻辑上的主动关系，故用现在分词短语作伴随状语，故C项正确。;4．表条件 Going there by plane, youll arrive tomorrow morning. ＝ If you go there by plane, youll arrive tomorrow morning. 如果你乘飞机去那里的话，明天早上就会到。 5．表让步 Having been told many times, he still made the same mistake. ＝ Though he had been told many times, he still made the same mistake. 尽管告诉他许多次了，他仍旧犯同样的错误。;6．表结果(必然结果) The train was caught in heavy snow, thus causing the delay. ＝ The train was caught in heavy snow and caused the delay. 火车遇上了大雪，因此造成了耽搁。;[考题印证4];解析：选 。考查非谓语动词。 句意：中国又建了一些高速公路，这使得人们从一个地方到另一个地方旅行更容易了。making 是现在分词，在句中作结果状语。不定式表示偶然性很强或意想不到的结果，所以C项不合题意。;三、使用动词-ing形式需注意的几个问题 1．动词-ing形式作状语时，其逻辑主语必须与句子的 主语一致。
