練習(xí)題-動(dòng)詞三單形式變化

動(dòng)詞第三人稱(chēng)單數(shù)形式變化練習(xí)題動(dòng)詞的第三人稱(chēng)單數(shù)形式是英語(yǔ)語(yǔ)法中的一個(gè)基礎(chǔ)知識(shí)點(diǎn)，也是日常使用和各類(lèi)英語(yǔ)測(cè)試中頻繁出現(xiàn)的考查點(diǎn)。掌握好這一變化規(guī)則，對(duì)于構(gòu)建正確的句子至關(guān)重要。本文將簡(jiǎn)要回顧相關(guān)規(guī)則，并提供針對(duì)性的練習(xí)題，幫助讀者鞏固和深化理解。規(guī)則回顧在一般現(xiàn)在時(shí)中，當(dāng)主語(yǔ)是第三人稱(chēng)單數(shù)（he,she,it，以及單個(gè)的人名、地名、事物名稱(chēng)等）時(shí)，謂語(yǔ)動(dòng)詞需要使用其第三人稱(chēng)單數(shù)形式。其變化規(guī)則主要如下：1.一般情況：直接在動(dòng)詞原形后加-s。例如：work→works,play→plays,eat→eats。2.以s,x,ch,sh或o結(jié)尾的動(dòng)詞：加-es。例如：pass→passes,fix→fixes,watch→watches,wash→washes,go→goes,do→does。*注意：少數(shù)以o結(jié)尾的動(dòng)詞只加-s，如：photo→photos,piano→pianos，但這類(lèi)詞在動(dòng)詞中相對(duì)少見(jiàn)，常見(jiàn)的需要加-es的動(dòng)詞如go,do,echo等需重點(diǎn)記憶。3.以輔音字母加y結(jié)尾的動(dòng)詞：先將y改為i，再加-es。例如：study→studies,fly→flies,worry→worries。*注意：若詞尾是“元音字母+y”，則直接加-s。例如：play→plays,enjoy→enjoys。4.不規(guī)則變化：英語(yǔ)中還有少數(shù)動(dòng)詞的第三人稱(chēng)單數(shù)形式是不規(guī)則的，需要特別記憶。最常見(jiàn)的如：have→has。練習(xí)題一、寫(xiě)出下列動(dòng)詞的第三人稱(chēng)單數(shù)形式請(qǐng)根據(jù)上述規(guī)則，寫(xiě)出下列動(dòng)詞的第三人稱(chēng)單數(shù)形式：1.speak2.like3.teach4.wash5.guess6.mix7.go8.do9.study10.carry11.fly12.cry13.play14.enjoy15.have16.make17.take18.give19.get20.forget二、用所給動(dòng)詞的適當(dāng)形式填空請(qǐng)根據(jù)句子主語(yǔ)的人稱(chēng)和數(shù)，用括號(hào)內(nèi)動(dòng)詞的第三人稱(chēng)單數(shù)形式填空：1.Sheoften______(read)booksintheevening.2.Myfatherusually______(drink)coffeeinthemorning.3.Thesun______(rise)intheeastand______(set)inthewest.4.Thiscat______(like)tosleeponthesofa.5.Healways______(brush)histeethtwiceaday.7.Thefactory______(produce)manydifferentproducts.8.She______(watch)TVforanhoureverynight.9.Theboy______(try)hisbesttosolvetheproblem.10.Water______(boil)at100degreesCelsius.11.He______(do)hishomeworkcarefullyeveryday.12.Mymother______(wash)thedishesafterdinner.14.She______(study)Englishveryhard.15.Thebird______(sing)beautifullyinthetree.三、改錯(cuò)(下列句子中動(dòng)詞第三人稱(chēng)單數(shù)形式有錯(cuò)誤，請(qǐng)找出并改正)1.Hegotoschoolbybuseveryday.2.Shedoherhomeworkintheafternoon.3.Thedogchasethecatacrossthegarden.4.MybrotherwatchTVeveryevening.5.Thisshopsellfreshvegetables.6.Hehavealotoffriends.7.Shestudyveryhardforherexams.8.Thesunriseinthemorning.9.Myfatherwashhiscareveryweekend.參考答案一、寫(xiě)出下列動(dòng)詞的第三人稱(chēng)單數(shù)形式1.speaks2.likes3.teaches4.washes5.guesses6.mixes7.goes8.does9.studies10.carries11.flies12.cries13.plays14.enjoys15.has16.makes17.takes18.gives19.gets20.forgets二、用所給動(dòng)詞的適當(dāng)形式填空1.reads2.drinks3.rises,sets4.likes5.brushes7.produces8.watches9.tries10.boils11.does12.washes13.has14.studies15.sings三、改錯(cuò)1.go→goes2.do→does3.chase→chases4.watch→watches5.sell→sells6
