It can serve in a sentence as the attribute, the predicative or the object complement. The verb-ing form can be used to indicate that two actions are happening at the same time. It has a perfect form. We should learn to identify its functions in different sentene. （一）Serve as the attribute (作定語(yǔ)) Attribute is a noun or an adjective that comes before a noun and describes it. If it is a phrase, it comes after the noun it modifies. Usually we can change it into an attributive clause. (作定語(yǔ)用的現(xiàn)在分詞如果是單詞，一般放在被修飾詞的前面；如果是現(xiàn)在分詞短語(yǔ)，則放在被修飾詞的后面，相當(dāng)于一個(gè)定語(yǔ)從句。) 如： There is a waiting taxi around the corner. Let’s go and take it. =>There is a taxi which is waiting around the corner. Let’s go and take it. 拐彎處有一輛出租車等在那兒。我們?nèi)コ俗伞? I like the room facing south. =>I like the room which is facing south. 我喜歡這間朝南的房間 (We can provide the students with more examples if necessary. Then have the students read Point 1 in Part 1 on Page 28 again.) （二）Serve as the predicative (作表語(yǔ)) Predicative is an adjective that comes after a linking verb. (現(xiàn)在分詞作表語(yǔ)時(shí)，多表示主語(yǔ)所具有的特征。一般跟在連系動(dòng)詞be, get, become, look, sound, feel, keep, remain, grow, seem, appear等后面。) 如： The story I heard from him yesterday sounded very frightening. 我昨天從他那兒聽(tīng)到的故事聽(tīng)起來(lái)非?？植馈? My brother’s job is designing new buildings. 我哥哥的工作是設(shè)計(jì)大樓。 (We can provide the students with more examples if necessary. Then ask the students to read Point 2 on Page 28.) （三）Serve as the object complement (作賓語(yǔ)補(bǔ)足語(yǔ)) An object complement is an adjective or a noun that relates to and describes the objects of a sentence. (現(xiàn)在分詞?？捎迷趙atch, see, hear, feel, find, get, keep, notice, have等詞后面作賓語(yǔ)補(bǔ)足語(yǔ)。) 如： He kept me waiting for a long time. 他讓我等了很久。 We heard someone singing in the next room. 我們聽(tīng)見(jiàn)有人在隔壁房間里唱歌。 (We can provide the students with more examples if necessary. Then have the students read Point 3 on Page 28.) （四）verb-ing phrase can be a verb-ing on its own. There can also be an object and / or adverbial after the verb-ing. Verb-ing phrases can express the time, the reason, the result, and the condition. Sometimes we can change verb-ing phrases into adverbial clauses. (現(xiàn)在分詞短語(yǔ)通?？梢詥为?dú)使用，也可以在其后面跟賓語(yǔ)和狀語(yǔ)，用來(lái)表示時(shí)間、原因、結(jié)果、條件、方式或伴隨情況等。通常可以轉(zhuǎn)換成相對(duì)應(yīng)的狀語(yǔ)從句。) 1．Express the time (表示時(shí)間) We can use clauses introduced by when and after to rewrite phrases showing the time. 如： Hearing the good news, he jumped with joy. =>After he heard the good news, he jumped with joy. 聽(tīng)到這個(gè)好消息，他高興地跳了起來(lái)。 Asking around, I found there were no students taking their mobile phones to that school. =>When I asked around, I found there were no students who took their mobile phones to that school. 當(dāng)向周圍的學(xué)生詢問(wèn)時(shí)，我發(fā)現(xiàn)他們沒(méi)人帶手機(jī)到學(xué)校。 2．Express the reason (表示原因) We can use clauses introduced by because to rewrite phrases showing the reason. 如： He went to the company with two of his designs, hoping to get a job there. =>He went to the company with two of his designs, because he hoped to get a job there. 他帶著兩張?jiān)O(shè)計(jì)去了那家公司，希望能在那兒找到一份工作。 Having no money in his pocket, he put down the book unwillingly. =>Because he had no money in his pocket, he put down the book unwillingly. 因?yàn)榭诖餂](méi)有錢(qián)，他不情愿地放下了書(shū)。 3．Express the result (表示結(jié)果) We can use as a result to rewrite phrases showing the result. 如： The car ran at an amazing speed, knocking into the wall. =>The car ran at an amazing speed. As a result, it knocked into the wall. 汽車以驚人的速度開(kāi)著，結(jié)果撞到了墻上。 Her mother died in 1966, leaving her with four younger brothers and sisters. =>Her mother died in 1966. As a result, she left her with four younger brothers and sisters. 1966年她母親死了，拋下她和四個(gè)弟妹。 4．Express the condition (表示條件) We can use clauses introduced by if to rewrite phrases showing the condition. 如： Turning to the left, you’ll find the post office there. =>If you turn to the left, you’ll find the post office there. 向左轉(zhuǎn)，你就能找到郵局。 Working hard, you will achieve your goal. =>If you work hard, you will achieve your goal. 努力工作，你會(huì)實(shí)現(xiàn)目標(biāo)。 (We can provide the students with more examples if necessary. Then have the students read Points 1-4 in Part 1 on Page 30.) 5．表示方式、伴隨情況或補(bǔ)充說(shuō)明等。Verb-ing can be used after verbs like stand, sit, and lie to show that the two actions are happening at the same time. 如： My father sat at the table, reading China Daily. =>My father sat the table, and read China Daily. 我父親坐在桌子旁，看《中國(guó)日?qǐng)?bào)》。 Please fill in the form, giving your name, address, etc. =>Please fill in the form, and give your name, address, etc. 請(qǐng)把這張表格填一下，寫(xiě)下你的姓名、住址等。 注意： 1．A verb-ing has a perfect form “having done” to show this verb happens before the main verb. And it also has its passive voice form “being done” and its perfect form “having been done”. (現(xiàn)在分詞有其完成時(shí)形式having done，表示其動(dòng)作先于主句謂語(yǔ)動(dòng)詞發(fā)生；也有其被動(dòng)形式being done及其完成時(shí)形式having been done。) 如： Having finished his homework, the boy watched TV for a short while. =>After the boy had finished his homework, he watched TV for a short while. 完成作業(yè)后，男孩看了會(huì)兒電視。 Being punished by his father, the boy felt sad. =>Because he was punished by his father, the boy felt sad. 由于受到了父親大懲罰，男孩感到很難過(guò)。 (We can provide the students with more examples if necessary. Then have the students read Part 3 on Page 28.) 2．We can also use the pattern conjunction + conjunction + verb-ing to express the time. (連詞when, whenever, while, once 和until通常可以加現(xiàn)在分詞短語(yǔ)，用來(lái)表示時(shí)間。) 如： He often keeps a dictionary at hand while learning English. =>He often keeps a dictionary at hand while he is learning English. 學(xué)英語(yǔ)時(shí)，他通常手頭會(huì)放一本詞典。 (We can provide the students with more examples if necessary. Then have the students read Part 2 on Page 30.) 3．Not should be put before the verb-ing to create its negative form. (現(xiàn)在分詞的否定式是由not+現(xiàn)在分詞構(gòu)成的。) 如: Not having received an answer, I wrote to him again. =>Because I hadn’t received an answer, I wrote to him again. 因?yàn)闆](méi)有收到回信，我又給他寫(xiě)了信。 (We can provide the students with more examples if necessary. Then have the students read Part 4 on Page 30.) 4．The understood subject of a verb-ing clause is usually the same as the subject of the main clause. (現(xiàn)在分詞短語(yǔ)作狀語(yǔ)時(shí)，它的邏輯主語(yǔ)一般應(yīng)與句子的主語(yǔ)一致。但有時(shí)它也可以有自己獨(dú)立的邏輯主語(yǔ)，這種結(jié)構(gòu)稱為獨(dú)立主格結(jié)構(gòu)或懸垂結(jié)構(gòu)。它通常用來(lái)表示伴隨的動(dòng)作或情況，有時(shí)還可表示時(shí)間、原因或條件等。) 如： They came into the classroom, talking and laughing. =When they came into the classroom, they talked and laughed. 他們走進(jìn)教室，邊說(shuō)邊笑。 So many people being absent, we decided to put off the meeting. 這么多人缺席，我們決定會(huì)議延期舉行。 Time permitting, we’ll go to visit a senior school. 時(shí)間允許的話，我們將參觀一所高中 (We can provide the students with more examples if necessary.
