Sectin Ⅱ　Discvering Useful Structures
语法点拨英语中分词分为现在分词和过去分词两种。现在分词由“动词＋-ing”形式构成，在句子中可以作定语、表语、宾语补足语和状语。现在分词的基本形式如下：现在分词一般式常表示该动作与句子谓语动作同时发生，而现在分词的完成式则表示该动作发生在谓语动作之前。
动词-ing形式作宾语补足语和状语
一、动词-ing形式作宾语补足语动词-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。(2019·江苏高考)A Mexican farmer was surprised t see smke rising frm a small part f his land.一位墨西哥农民惊讶地发现从他的一小块地里冒出了烟。I felt my heart beating vilently when I was seeing the 70th anniversary f fundatin f the Peple's Republic f China.我看中华人民共和国成立70周年庆典的时候，感到心潮澎湃。
1．动词-ing形式在感官动词后作宾语补足语在see，hear，feel，watch，ntice等感官动词后，用动词的-ing形式构成复合宾语，表示一个正在进行的主动的动作，强调一个过程或一种状态。In the crwded cafe, I heard a friendly vice saying, “Yu can share my table.”在一个拥挤的咖啡馆，我听到一个友好的声音在说：“你可以和我坐一桌。”He saw a girl wandering n the street this time yesterday.他昨天这个时候看到一个女孩正在街上闲逛。
在see，hear，feel，watch，ntice等感官动词后，既可用动词的-ing形式构成复合宾语，也可用省略t的不定式构成复合宾语，两者之间有一定的区别。用动词的-ing形式时，表示动作正在进行；用省略t的不定式时，表示动作发生了，即动作的全过程结束了。Tday n my way hme, I saw a man running alng the street hurriedly.今天在我回家的路上，我看到一个男人正匆忙从街上跑过。I saw him enter the rm and take smething away.我看到他进入房间，并带着东西离开了。
完成句子①I _________ a thief stealing mney frm the ld wman's pcket yesterday.昨天我注意到一个小偷正在从那位上年纪的女士口袋里偷钱。②She ________________________ at the dr.她听到有人在敲门。
heard smene kncking
③He ________________________________.他看见一个女孩上车把车开走了。④Can yu __________________ the sng in the next rm?你能听见她在隔壁唱歌吗？
saw a girl get n the car and drive ff
hear her singing
2．动词-ing形式在使役动词宾补结构中的使用使役动词have接现在分词作宾语补足语，表示“让……一直做某事”。It's cld.We shuld have the fire burning all the time.天气冷。我们应该让火一直燃烧着。I wn't have yu running abut in the rm.我不允许你在房间里跑来跑去。
(1)have/get＋宾语＋dne，dne是过去分词作宾语补足语。包括两层意思：①让别人去做某事He will have/get the cmputer repaired tmrrw.他明天让人给他修电脑。②(主语)遭受到(意外的损失或不幸)He had/gt his cmputer stlen the ther day.前几天他的电脑被偷了。
(2)have＋宾语＋d sth.意思是“让某人去干某事”Mther has me g t the shp t buy sme fruit.妈妈让我去商店买一些水果。
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 infrmed f children's perfrmance in the kindergarten by sharing vides n WeChat.许多老师通过在微信上分享视频让家长知晓孩子们在幼儿园的表现。
单句语法填空①Mr. Smith suggested a gd way t have her written English ________ (imprve) in a shrt perid.②Dn't leave the water _________(run) while yu brush yur teeth.③Mther has the little girl ______(play) the pian this afternn.④He needed t have sme paperwrk ___________(deliver) acrss the cuntry the next day.
delivered
3．现在分词在with复合结构中的应用在with复合结构中，现在分词充当宾语补足语，表动作“正在进行”。Singing “Yu dn't knw lve, Fa Hai”， she threw the trtise int the river, with tears filling her eyes.她唱着《法海你不懂爱》，把那只乌龟扔进了河里，眼里满是泪水。
(2019·全国卷Ⅰ)Des Kilimanjar deserve its reputatin as a crwded muntain with lines f turists ruining the atmsphere f peace?乞力马扎罗山是一座拥挤的山，挤满了成群的游客，破坏了它宁静的气氛，它应得这样的声誉吗？
在with的复合结构中，也可以使用不定式和过去分词作宾语补足语。All the afternn he wrked with the dr lcked.整个下午他都锁着门在房里工作。I can't g ut with all these clthes t wash.要洗这些衣服，我无法出去了。
单句语法填空①I lve my schl with students _________(wrk) hard t realize their dreams and teachers _________(help) us like ur parents.②(2019·江苏高考)China's image is imprving steadily, with mre cuntries _____________(recgnize) its rle in internatinal affairs.③With Christmas _____________(apprach), a Christmas party will be held in the schl.
recgnizing
appraching
二、动词-ing形式作状语动词-ing形式可以作状语，修饰动词，在句中表示时间、原因、结果、条件、让步、行为方式或伴随情况等。-ing形式作时间、原因、条件、让步状语时多位于句首；作结果、伴随情况状语时常位于句末。Swallwing Little Red Hat, the wlf went t bed and slept.大灰狼吞下了小红帽，然后上床睡觉了。(时间状语)I feel prud knwing yur interest in Chinese histry.得知你对中国历史感兴趣我很高兴。(原因状语)
1．动词-ing形式表示时间。Walking in the park，she saw an ld friend.＝When/While (she was) walking in the park，she saw an ld friend.当她在公园里散步时，她看到了她的一个老朋友。(2019·全国卷Ⅰ)Hearing these stries, I'm skeptical abut the place.(＝When I heard these stries...)当我听到这些故事的时候，我对这个地方有点怀疑。

6．动词-ing形式表示行为方式、伴随情况或补充说明。He lay n the grass, staring at the sky fr a lng time.(＝ stared at the sky fr a lng time.)他躺在草地上，长时间地望着天空。7．作方式状语He came running back t tell me the news.他跑回来告诉我这个消息。
非谓语动词作状语时，如果提供的动词不能和句子中的主语保持一致，动词-ing形式必须有自己的逻辑主语，通常由名词或人称代词(主格)来担任，这就是独立主格结构。The last bus having gne, we had t walk hme.末班车已经开走了，我们不得不走回家。(having gne的逻辑主语是the last bus，而不是we)Weather permitting, the ftball match will be played n Friday.天气允许的话，足球赛将在周五举行。(permitting的逻辑主语是time，而不是the ftball match)
