知識(shí)梳理知識(shí)梳理一、現(xiàn)在進(jìn)行時(shí)的用法現(xiàn)在進(jìn)行時(shí)表示現(xiàn)在正在進(jìn)行或正在發(fā)生的動(dòng)作，也可以表示當(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。句型結(jié)構(gòu)是：be+ving形式（現(xiàn)在分詞）。標(biāo)志時(shí)間詞：now，look，listen，over there，look at，Its+時(shí)間等。二、現(xiàn)在分詞的變化規(guī)則1一般情況下，在動(dòng)詞詞尾加ing。如：gogoing,playplaying,eateating 2.以不發(fā)音的字母e結(jié)尾的動(dòng)詞，去e再加ing。如：writewriting,comecoming,taketaking 3.以重讀閉音節(jié)結(jié)尾，且詞尾只有一個(gè)輔音字母的動(dòng)詞，雙寫(xiě)最后這個(gè)輔音字母再加ing。如：runrunning,swimswimming,shopshopping 4.以ie結(jié)尾的動(dòng)詞，將ie改為y,再加ing。如：diedying,lielying三、現(xiàn)在進(jìn)行時(shí)的句型結(jié)構(gòu)1肯定句：主語(yǔ)+be動(dòng)詞(am/are/is)+ving+其他.如：I am washing my hands now.Look！Jack is listening to music.Tom and his brother are doing their homework.It is nine oclock.The children are having class.2.否定句：主語(yǔ)+be動(dòng)詞(am/are/is)+not+ving+其他.如：I am not(Im not)washing my hands now.The children are not(arent)playing over there.Its six past ten.Tom is not(isnt)having dinner.3.一般疑問(wèn)句：Is/Are/Am+主語(yǔ)+ving+其他？如：Are you watching TV now?Yes,I am./No,I am not.Is the girl playing the piano?Yes,she

boys(sing).解析:本題考查填動(dòng)詞的適當(dāng)形式，必須要弄清楚句子的時(shí)態(tài)。第1小題中的時(shí)間詞now，第2小題中的Listen 都表示動(dòng)作正在發(fā)生，都要用現(xiàn)在進(jìn)行時(shí)；同時(shí)，注意ving 之前一定要根據(jù)主語(yǔ)的形式加上相應(yīng)的be動(dòng)詞。答案：1.is drawing 2.are singing舉一反三 1.寫(xiě)出下列動(dòng)詞的現(xiàn)在分詞形式。(1)sing _ (2)dance _ (3)write _(4)shop _ (5)put _ (6)die _ 2.單項(xiàng)填空。()(1)Mum and I

解析:本題考查現(xiàn)在進(jìn)行時(shí)的句型轉(zhuǎn)換，要以be動(dòng)詞為中心進(jìn)行變化。第1小題改否定句，只要在be動(dòng)詞之后加not;第2小題是對(duì)進(jìn)行時(shí)狀態(tài)下的活動(dòng)提問(wèn)，用“What doing?”，注意be動(dòng)詞要與主語(yǔ)的數(shù)保持一致。第3小題要將原句中的謂語(yǔ)動(dòng)詞換成“is+現(xiàn)在分詞”，因?yàn)檫@才是現(xiàn)在進(jìn)行時(shí)的正確形式。答案：1.Sarah is not(isnt)answering the phone.2.What are they doing？3.She is
