I+am+v-ing

we/you/they+are+v-ing

he/she/it+is+v-ing

定義：現(xiàn)在進(jìn)行時(shí)表示現(xiàn)在或當(dāng)前一般時(shí)間正在進(jìn)行的動(dòng)作。

【No.1】現(xiàn)在進(jìn)行時(shí)的構(gòu)成

現(xiàn)在進(jìn)行時(shí)由"be+v-ing"構(gòu)成。be應(yīng)為助動(dòng)詞，初學(xué)者最容易漏掉，它應(yīng)與主語(yǔ)的人稱和數(shù)保持一致?！綨o.2】現(xiàn)在進(jìn)行時(shí)的應(yīng)用當(dāng)句子中有now時(shí)，常表示動(dòng)作正在進(jìn)行，這時(shí)要用現(xiàn)在進(jìn)行時(shí)。如：

Theyareplayingbasketballnow.現(xiàn)在他們正在打籃球。

(2)以look,listen開(kāi)頭的句子，提示我們動(dòng)作正進(jìn)行，這時(shí)要用現(xiàn)在進(jìn)行時(shí)。如：Listen！SheissinginganEnglishsong.聽(tīng)，她正在唱英語(yǔ)歌。

【No.3】現(xiàn)在進(jìn)行時(shí)的變化

肯定句式：主語(yǔ)+be(am,is,are)+現(xiàn)在分詞+其它.

否定句式：主語(yǔ)+be(am,is,are)+not+現(xiàn)在分詞+其它.

一般疑問(wèn)句：Be(am,is,are)+主語(yǔ)+現(xiàn)在分詞+其它？

特殊疑問(wèn)句：疑問(wèn)詞+be(am,is,are)+主語(yǔ)+現(xiàn)在分詞+其它？

對(duì)現(xiàn)在進(jìn)行時(shí)的特殊疑問(wèn)句的回答，它不可以用Yes或No直接作答，要根據(jù)實(shí)際情況回答。

有一些特殊變化(或者說(shuō)以ie為結(jié)尾的重讀閉音節(jié)的動(dòng)詞)的現(xiàn)在分詞〔有3個(gè)〕,:lying—lie,dying―dietying―tie這些以ie結(jié)尾要去e再把I變y再加ing．隨堂練習(xí)在橫線上寫出下列動(dòng)詞的現(xiàn)在分詞形式。carry______eat______burn______send______rain______become______argue______escape______live______lie______die______begin______put______sit______請(qǐng)改正句子中錯(cuò)誤的地方。Iwatchingtelevision._________________________Heislistentomusic._________________________Theyareeatlunch._________________________Sheiswritealetter._________________________YeQingisshop._________________________用所給動(dòng)詞的正確形式填空。Ada:Hi,Bob.Bob:Hi,Ada.What__________________(you/do)Ada:We__________________(play)atthebeach.Grace__________________(fish)andIvan__________________(swim).Bob:What__________________(Johnny/do)?Ada:He__________________(listen)themusic.Therearelotsofpeoplehere.CarolandTed__________________(play)volleyball.JennyandHenry__________________(play)theguitar.AndDora__________________(eat)icecream.Bob:__________________(you/have)agoodtime?Ada:Yes,we__________________(be).Dad,seeyoulater.4、單選1.Look!Peter________TVhappily,buthisparentsarebusyinthekitchen.A.iswatchingB.watchesC.watchedD.willwatch——MayIspeaktotheprincipal?——Sorry,he_______ameetingnow.CanItakeamessage?A.ishavingB.hadC.hasD.willhaveWhereisSally?Hermother_______forhereverywhere.A.looksB.lookedC.islookingD.waslooki
