She is singing an English song.聽,她正在唱英語歌.Look at the picture. The children are flying kites in the park.看這幅圖.那些孩子正在公園放風(fēng)箏.We are making model planes these days.這些天我們在做飛機(jī)模型.It's 6:30 now. I am getting up. 現(xiàn)在是6：30.我正在起床. 編輯本段句型分析1.一般疑問句是將be移到主語前面,句末加問號,讀升調(diào).be+主語+doing sthAre they putting up the scaffolding? Yes, they are. / No, they aren' he showing a foreign guest round the city? Yes, he is. / No, he isn'.否定句式是在be動(dòng)詞后加not.主語+be+not+doing sthI am not isn't runnig or the students aren't playing football. 編輯本段使用場合1.當(dāng)句中出現(xiàn)的表示時(shí)間的詞是now, at the moment (此刻、現(xiàn)在)等時(shí),表示句子要說明的是現(xiàn)在正在發(fā)生的事,動(dòng)詞應(yīng)用現(xiàn)在進(jìn)行時(shí).Linda's brother is watching TV in his bedroom now.琳達(dá)的哥哥現(xiàn)在正在他的臥室里看電視.We're far from home. What are our parents doing at the moment?我們現(xiàn)在遠(yuǎn)離家,我們的父母此刻在干什么呢?2.當(dāng)句中出現(xiàn)的時(shí)間狀語是these days, this week, this month等時(shí),如果句子所要表達(dá)的意義是在這一階段正在發(fā)生的事,則動(dòng)詞應(yīng)用現(xiàn)在進(jìn)行時(shí).These days we are helping the farmers work on the farm. 這些天我們在農(nóng)場幫農(nóng)民們干活.They're having a test this week. 這一周他們在進(jìn)行一次考試.Mr Cheng is visiting our village this month. 這個(gè)月程先生在我們村訪問.3.在句中出現(xiàn)了Look, Listen, Can't you see? 等暗示詞時(shí),說明后面謂語動(dòng)詞的動(dòng)作正在發(fā)生,該動(dòng)詞應(yīng)用現(xiàn)在進(jìn)行時(shí).Look! Maria and Tom are dancing under the tree.看!瑪麗亞和湯姆正在樹下跳舞.Listen! Our English teacher is singing the popular English song.聽!我們英語老師正在唱那首流行的英文歌曲.Many children are swimming in the river. Can't you see?許多小孩在河里游泳,你難道看不見嗎?4.注意根據(jù)上下文的暗示,句子的謂語動(dòng)詞可能應(yīng)用現(xiàn)在進(jìn)行時(shí).— Where is Mr Wang?王先生在哪兒?— Oh, he is reading a newspaper in the office. 噢,他正在辦公室看報(bào).（問句詢問王先生在哪兒,應(yīng)說明他現(xiàn)在在哪兒,故答句應(yīng)說明他現(xiàn)在正在做的事,用現(xiàn)在進(jìn)行時(shí).）—Is that boy Jack?那個(gè)男孩是杰克嗎?— No,Jack is doing his homework in the classroom. 不是,杰克正在教室做作業(yè)呢.（答句中說明的杰克做作業(yè)的情況應(yīng)發(fā)生在現(xiàn)在,應(yīng)用現(xiàn)在進(jìn)行時(shí).） 編輯本段注意事項(xiàng)1.在英語中,并不是所有的動(dòng)詞都要使用正在進(jìn)行時(shí).例如一些表示狀態(tài)和感覺的動(dòng)詞,一般不用進(jìn)行時(shí)態(tài),而是用現(xiàn)在一般時(shí)表示.例如：I hear someone singing. 我正聽見有人唱歌.Do you see anyone over there? 你看到那里有什么人嗎?What does he think of it? 他覺得這怎么樣?如果這些詞使用正在進(jìn)行時(shí)態(tài),句子帶有某種感情色彩.例如：Are you seeing someone off? 你在給誰送行嗎?They are hearing an English talk. 他們在聽一個(gè)英語報(bào)告.2.現(xiàn)在進(jìn)行時(shí)還有另外一種含義,即它們能表達(dá)即將發(fā)生的事情,相當(dāng)于一般將來時(shí).能夠用來表示將來狀況的動(dòng)詞有：arrive, come, do, get, go, have, leave, meet, play, return, see, spend, start, stay, wear, work等.We are leaving on Friday.我們星期五出發(fā).Are you going anywhere tomorrow?你明天準(zhǔn)備去哪兒?A foreign guest is giving a lecture this afternoon.今天下午一個(gè)外國客人將給我們作報(bào)告.Are you staying here till next week? 你打算在這里呆到下個(gè)星期嗎?在表示將來的情況下,特別是be going to do sth. 這種結(jié)構(gòu),已經(jīng)沒有多少“去”的意思了,幾乎就是用來表達(dá)“將要、打算”做什么事情.例如：It is going to be rather cold tomorrow.明天很可能非常冷.She is not going to speak at the meeting.她不打算在那個(gè)會(huì)上發(fā)言.3.當(dāng)其與always、forever、continually、constantly 等副詞連用時(shí)表示重復(fù)的動(dòng)作,而這種動(dòng)作可能使人不滿,厭倦或滿意.例如：①She is perpetually interfering in my affairs.她老是干預(yù)我的事. （不滿）②The students are making progress constantly.學(xué)生們在不斷進(jìn)步. （滿意）現(xiàn)在進(jìn)行時(shí)的標(biāo)志有很多,如：listen,look,now,these days,Be quiet!/Don't talk等等. 編輯本段特殊情況1.有些動(dòng)詞從結(jié)構(gòu)來看是現(xiàn)在進(jìn)行時(shí),但卻是表示將要發(fā)生的事,而不表示動(dòng)作現(xiàn)在正在進(jìn)行.這些動(dòng)詞往往是一些表示位置移動(dòng)變化的動(dòng)詞,如：go , come , leave , fly , move, start, begin , arrive, , stay, return等.Next month my family is moving to Beijing.下個(gè)月,我家就要搬到北京去了.(搬的動(dòng)作并非現(xiàn)在發(fā)生,而將在下個(gè)月發(fā)生.)My aunt is leaving for Shanghai at eleven o'clock tomorrow morning.明天早上十一點(diǎn)我嬸嬸將離開去上海.2.并不是所有動(dòng)詞都有進(jìn)行時(shí),一些動(dòng)詞一般在句中不能用現(xiàn)在進(jìn)行時(shí)態(tài),而應(yīng)用一般現(xiàn)在時(shí).這些動(dòng)詞往往是等表示情感狀態(tài)、知覺認(rèn)識、愿望或短暫性的動(dòng)詞.例如：see（明白）,know, want, like, hear, have(有), think, hope, hate等.3.在時(shí)間、條件狀語從句中,有時(shí)可用現(xiàn)在進(jìn)行時(shí)代替一般將來時(shí).When you are passing my way,please drop in.你什么時(shí)候路過我家,請進(jìn)來坐. 編輯本段被動(dòng)語態(tài)現(xiàn)在進(jìn)行時(shí)現(xiàn)在進(jìn)行時(shí)由主動(dòng)語態(tài)變被動(dòng)語態(tài)時(shí)應(yīng)注意以下一些問題：1.也像其它時(shí)態(tài)由主動(dòng)語態(tài)變被動(dòng)語態(tài)一樣,首先弄清楚用現(xiàn)在進(jìn)行時(shí)的句子中哪些可以由主動(dòng)語態(tài)變?yōu)楸粍?dòng)語態(tài).我們知道,在簡單句的五個(gè)基本句型中,有三個(gè)基本句型(S V O,S V o O,S V O C)可以由主動(dòng)語態(tài)變?yōu)楸粍?dòng)語態(tài)；有兩個(gè)基本句型(S V,S V P)不能由主動(dòng)語態(tài)變?yōu)楸粍?dòng)語態(tài).所以,當(dāng)這三個(gè)基本句型(S V O,S V InO DO,S V O OC)的謂語動(dòng)詞用了現(xiàn)在進(jìn)行時(shí)時(shí)才有可能由主動(dòng)語態(tài)變?yōu)楸粍?dòng)語態(tài).例如：They are studying the milu deer at the research centre.(S V O)→The milu deer are being studied at the research is teaching the boy a lesson.(S V InO DO)→The boy is being taught a he is making the girl laugh.(S V O OC)→Now the girl is being made to laugh.還應(yīng)注意到一些動(dòng)詞很少用于被動(dòng)語態(tài),因此這些動(dòng)詞在句子謂語用了現(xiàn)在進(jìn)行時(shí)時(shí)也常沒有被動(dòng)語態(tài).如：We are having supper now.一般不能變?yōu)镾upper is being had now..2.及物動(dòng)詞現(xiàn)在進(jìn)行時(shí)由主動(dòng)語態(tài)變被動(dòng)語態(tài)時(shí)有三種句式：①主語(第一人稱單數(shù)I) am being 過去分詞 其他成分；②主語(第二人稱單、復(fù)數(shù)you,第一人稱復(fù)數(shù)we和第三人稱復(fù)數(shù)they等) are being 過去分詞 其他成分；③主語(第三人稱單數(shù) he,she,it等) is being 過去分詞 其他成分.所以,當(dāng)句子謂語動(dòng)詞用了現(xiàn)在進(jìn)行時(shí)由主動(dòng)語態(tài)變被動(dòng)語態(tài)時(shí)謂語動(dòng)詞要由原來作賓語變?yōu)橹髡Z時(shí)的名(代)詞的數(shù)來決定,從上面三種句式中選擇合適的一種句式.例如：They are collecting money for the broadband project.→Money is being collected for the broad-band are not protecting some animals well enough.→Some animals are not being protected well .當(dāng)變?yōu)橹髡Z的原來的賓語(名/代詞)有較長的動(dòng)詞不定式短語(復(fù)合結(jié)構(gòu))、介詞短語、從句修飾或有補(bǔ)足語時(shí),動(dòng)詞不定式短語、介詞短語、從句和補(bǔ)足語等,一般都仍然保留在原來的位置上.例如：They are revising the laws to protect the rights of women and children.→The laws are being revised to protect the rights of women and are writing a report about the negative effects of cell phones in school.→A report is being written about the negative effects of cell phones in are keeping a sick milu deer alive at the centre.→A sick milu deer is being kept alive at the centre(by scientists).4.如果用在現(xiàn)在進(jìn)行時(shí)的句子中的謂語動(dòng)詞是動(dòng)詞短語或習(xí)慣用語,那么這個(gè)動(dòng)詞短語或習(xí)語只把動(dòng)詞變?yōu)楸粍?dòng)語態(tài),其他部分保持不變.例如：The parents are taking good care of their test-tube baby.→Their test-tube baby is being taken good care of(by the parents).5.當(dāng)用了現(xiàn)在進(jìn)行時(shí)的句子結(jié)構(gòu)是"S V In O DO"句型時(shí),既可以把間接賓語變?yōu)楸粍?dòng)句的主語,也可以把直接賓語變?yōu)楸粍?dòng)句的主語,但如果是后者,可根據(jù)動(dòng)詞的習(xí)慣用法,把間接賓語改寫為to或for引起的介詞短語.例如：George is sending his friend's phone texts and friend's phone is being sent texts and pictures(by George).Texts and pictures are being sent to his friend's phone(by George).She is making Toma new is being made a new new coat is being made for .用了現(xiàn)在進(jìn)行時(shí)的句子由主動(dòng)語態(tài)變?yōu)楸粍?dòng)語態(tài)后,原來充當(dāng)主語的名/代詞(特別是人稱代詞)在一般情況下可以省略掉,如果有必要強(qiáng)調(diào)時(shí)可用by表示,常放在句子后面.例如：They are adding new functions to the functions are being added to the phones(by them).Scientists are studying the life of the milu deer at life of the milu deer is being studied at present by .當(dāng)用了現(xiàn)在進(jìn)行時(shí)的句子由主動(dòng)語態(tài)變?yōu)楸粍?dòng)語態(tài)后,其否定式的構(gòu)成主要把not放在謂語動(dòng)詞中第一個(gè)助動(dòng)詞(am ,are或is)后面構(gòu)成,而疑問式的構(gòu)成則是把句子謂語動(dòng)詞的第一個(gè)助動(dòng)詞(am,are或is)移到句子前(第一個(gè)字母要大寫),然后在句子后面加上問號而成.例如：New nature parks are being started in nature parks are not being started in China.(否定式)Milu deer are being sent to China from milu deer being sent to China from Britain?(疑問式)如果是特殊疑問句還要在這個(gè)助詞前面加上適當(dāng)疑問詞.例如：Why is money being collected? 編輯本段與一般現(xiàn)在時(shí)區(qū)別一般現(xiàn)在時(shí)表示經(jīng)常性動(dòng)作,現(xiàn)在進(jìn)行時(shí)表示現(xiàn)在或現(xiàn)階段正在發(fā)生的動(dòng)作.例如：He studies hard. 他（經(jīng)常）努力學(xué)習(xí).He is studying hard. 他（此刻或現(xiàn)階段）正在努力學(xué)習(xí).一般現(xiàn)在時(shí)表示現(xiàn)在發(fā)生的動(dòng)作,現(xiàn)在進(jìn)行時(shí)表示眼前看得見的動(dòng)作.例如：Boats pass under the bridge. 船從橋下穿過.The boat is passing under the bridge.船正從橋下穿過. 編輯本段基本用法（1）表示（說話瞬間）正在進(jìn)行或發(fā)生的動(dòng)作.（2）也可表示當(dāng)前一段時(shí)間內(nèi)的活動(dòng)或現(xiàn)階段正在進(jìn)行的動(dòng)作. （二）謂語構(gòu)成：be (am/ is/ are)+v-ing （動(dòng)詞的現(xiàn)在分詞）I’m watching TV ’re playing football.（三）現(xiàn)在分詞的構(gòu)成.（1）一般情況下在動(dòng)詞詞尾加→going ask →asking look→looking（2）以不發(fā)音的e結(jié)尾的動(dòng)詞,去掉e加 →having take→taking make→making write→writing（3）以一個(gè)輔音字母結(jié)尾的重讀閉音節(jié),雙寫最后一個(gè)字母,再加→getting sit→sitting put→putting run→runningswim→swimming begin→beginning shop→shopping（四）現(xiàn)在進(jìn)行時(shí)態(tài)的肯定式、否定式、疑問式及簡略回答.（1）肯定式：be+v-ing She is singing in the next room.（2）否定式：be+not+v-ing The students aren’t cleaning the room.（3）一般問句：be動(dòng)詞提前.肯定答語Yes,主語+be,否定答語No,主語+be you playing the computer game? Ye
