1、現(xiàn)在進(jìn)行時(shí)詳解和習(xí)題大家知道,謂語(yǔ)的動(dòng)詞用來(lái)表示動(dòng)作(情況)發(fā)生時(shí)間的各種形式稱(chēng)為時(shí)態(tài)?,F(xiàn)在進(jìn)行時(shí)表示:1、現(xiàn)在(說(shuō)話的瞬間)正在進(jìn)行或發(fā)生的動(dòng)作,強(qiáng)調(diào)“此時(shí)此刻”。e.g.Heisreading.Theyaretalkingnow. 2、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。e.g.Theyareworkingthesedays. 3、某些動(dòng)詞的現(xiàn)在進(jìn)行時(shí),表預(yù)定的計(jì)劃或即將發(fā)生的動(dòng)作。e.gIamcoming. 其結(jié)構(gòu)為be+現(xiàn)在分詞.現(xiàn)在分詞的變法有 1、一般在動(dòng)詞詞尾加上-ing,e.g.jumping 2、以不發(fā)音字母e結(jié)尾的動(dòng)詞,先去e,再加-ing.e.g
2、having,writing3、如果末尾是一個(gè)元音字母和一個(gè)輔音字母,雙寫(xiě)末尾的輔音字母,再加ing,如:run-running,stop-stoppingsit-sittingget-gettingforget-forgettingbegin-beginning4、以ie結(jié)尾的動(dòng)詞,改ie為y加ing,die--dying??lie--lying 其句式變換都在be上做文章?!.g.Heisbuyingabike. Ishebuyingabike? Heisn’tbuyingabike. 一般由look,listen,引起的祈使句及now,atthismoment等時(shí)間狀語(yǔ)做標(biāo)
3、志?!”M管現(xiàn)在進(jìn)行時(shí)比較簡(jiǎn)單,但在做題過(guò)程中也常會(huì)犯一些錯(cuò)誤,常見(jiàn)的錯(cuò)誤:一、把動(dòng)詞變成現(xiàn)在分詞形式易出錯(cuò) 例:1、Theyareswiming.(swim) 2、Jennyisplaiing(play)football. 答案:1.swimming2.playing 解析:動(dòng)詞變現(xiàn)在分詞可有如下口訣:“一添一去y不變”.“一添”指雙寫(xiě)規(guī)則;“一去”指去掉不發(fā)音字母e規(guī)則;“y不變”指要與名詞變復(fù)數(shù)區(qū)分開(kāi)?! 《?、丟掉be動(dòng)詞或忘記把動(dòng)詞變成現(xiàn)在分詞 例:1、Look,twochildrenflying.(fly)akiteinthepark. 2、LiMingisn’tr
4、ead(notread)abookinbednow. 答案:1areflying2isn’treading 解析:現(xiàn)在進(jìn)行時(shí)肯定句的結(jié)構(gòu)規(guī)律為:“be+現(xiàn)在分詞,缺一不可”。這一點(diǎn)必須牢記?! ∪?、對(duì)動(dòng)詞或動(dòng)詞詞組提問(wèn)時(shí)丟掉doing 例:1、Thestudentsaresingingintheroom.(對(duì)劃線部分提問(wèn)) Whatarethestudentsintheroom? 答案:Whatarethestudentsdoingintheroom? 解析:現(xiàn)在進(jìn)行時(shí)態(tài)中對(duì)動(dòng)作提問(wèn)可記住此句式“What+be+主語(yǔ)+doing+其它?” 或簡(jiǎn)寫(xiě)為“What......d
5、oing......”?句式?! ∷?、現(xiàn)在進(jìn)行時(shí)態(tài)的選擇疑問(wèn)句中易忽視or后用現(xiàn)在分詞形式 例:孩子們?cè)谂苓€是在跳? Arethechildrenrunningorjump? 答案:Arethechildrenrunningorjumping? 解析:or連接的是兩個(gè)并列成分,動(dòng)詞形式須一致。 自我檢測(cè) ?。ㄒ唬?、單選(20分;3分鐘)1、Look!He_____theirmotherdothehousework.
