人教版七年級(jí)英語(yǔ)語(yǔ)法重點(diǎn)突破練習(xí)七年級(jí)是英語(yǔ)學(xué)習(xí)打基礎(chǔ)的關(guān)鍵時(shí)期，語(yǔ)法則是構(gòu)建英語(yǔ)知識(shí)體系的重要支柱。本練習(xí)聚焦人教版七年級(jí)英語(yǔ)核心語(yǔ)法點(diǎn)，通過(guò)針對(duì)性的梳理與實(shí)戰(zhàn)演練，幫助同學(xué)們夯實(shí)基礎(chǔ)，提升運(yùn)用能力。請(qǐng)同學(xué)們?cè)诰毩?xí)過(guò)程中認(rèn)真思考，及時(shí)總結(jié)，真正做到學(xué)以致用。一、名詞的數(shù)與格要點(diǎn)點(diǎn)撥：名詞是表示人、事物、地點(diǎn)或抽象概念的詞。我們首先要掌握名詞的單復(fù)數(shù)變化規(guī)則，特別是不規(guī)則變化（如man-men,child-children）。其次，名詞所有格用于表示所屬關(guān)系，單數(shù)名詞通常加's，復(fù)數(shù)名詞以s結(jié)尾的只加'，不以s結(jié)尾的加's。實(shí)戰(zhàn)演練1.用所給名詞的適當(dāng)形式填空。*Therearethree_______(book)onthedesk.*Ihavetwo_______(foot).*Thisismy_______(sister)bag.*The_______(teacher)officeisoverthere.2.單項(xiàng)選擇。*Lookatthe_______.Theyareplayinghappily.A.childB.childsC.childrenD.childrens*Thisis_______room.A.LucyandLilyB.Lucy'sandLily'sC.LucyandLily'sD.LucysandLilys二、be動(dòng)詞的用法要點(diǎn)點(diǎn)撥：be動(dòng)詞（am,is,are）是我們最早接觸的動(dòng)詞之一，也是使用頻率極高的詞。其基本用法是：我(I)用am，你(you)用are，is連著他(he)、她(she)、它(it)。單數(shù)名詞用is，復(fù)數(shù)名詞全用are。變否定，be后not；變疑問(wèn)，be提句首。實(shí)戰(zhàn)演練1.用be動(dòng)詞的適當(dāng)形式填空。*I_______astudent.Myname_______LiMing.*They_______fromBeijing.Theirparents_______teachers.*_______thisyourpencil?Yes,it_______.*Thebooks_______ontheshelfyesterday,butnowthey_______notthere.(提示：雖然七年級(jí)下冊(cè)才重點(diǎn)學(xué)過(guò)去時(shí)，但此處可簡(jiǎn)單理解yesterday用was/were)2.句型轉(zhuǎn)換（改為否定句和一般疑問(wèn)句，并作肯定/否定回答）。*Tomisintheclassroom.否定句：_________________________________一般疑問(wèn)句：_____________________________肯定回答：_______________________________否定回答：_______________________________三、情態(tài)動(dòng)詞can的用法要點(diǎn)點(diǎn)撥：情態(tài)動(dòng)詞can表示“能，會(huì)”，其后接動(dòng)詞原形。它沒(méi)有人稱(chēng)和數(shù)的變化。否定形式是can't(cannot)，疑問(wèn)形式是將can提到主語(yǔ)之前。實(shí)戰(zhàn)演練1.用can或can't填空。*I_______swim,butI_______skate.It'stoodifficult.*_______youspeakEnglish?Yes,I_______.*He_______playthepianoverywell.2.根據(jù)中文提示完成句子。*我會(huì)唱歌和跳舞。I______________and_______.*她不會(huì)打籃球。She______________basketball.四、指示代詞this,that,these,those要點(diǎn)點(diǎn)撥：this（這個(gè)）和these（這些）指離說(shuō)話人較近的人或物；that（那個(gè)）和those（那些）指離說(shuō)話人較遠(yuǎn)的人或物。this/that后接單數(shù)名詞，these/those后接復(fù)數(shù)名詞。在回答主語(yǔ)是this/that的疑問(wèn)句時(shí)，常用it代替；回答主語(yǔ)是these/those的疑問(wèn)句時(shí)，常用they代替。實(shí)戰(zhàn)演練1.單項(xiàng)選擇。*_______ismypen._______areyourpencils.A.This;ThatB.These;ThoseC.This;TheseD.That;This*—What's_______overthere?—It'sabike.A.thisB.thatC.theseD.those*—Are_______yourbooks?—Yes,theyare.A.thisB.thatC.theseD.it2.根據(jù)圖片提示，用this/that/these/those完成對(duì)話。(假設(shè)有兩張圖片，近處一張有幾只貓，遠(yuǎn)處一張有幾只狗)*A:Whatare_______(近處圖片上的貓)?B:_______arecats.*A:Whatare_______(遠(yuǎn)處圖片上的狗)?B:_______aredogs.五、物主代詞要點(diǎn)點(diǎn)撥：物主代詞表示所屬關(guān)系，分為形容詞性物主代詞和名詞性物主代詞。形容詞性物主代詞（my,your,his,her,its,our,your,their）相當(dāng)于形容詞，后面必須接名詞。名詞性物主代詞（mine,yours,his,hers,its,ours,yours,theirs）相當(dāng)于名詞，可以獨(dú)立使用，后面不接名詞。實(shí)戰(zhàn)演練1.用括號(hào)內(nèi)所給詞的適當(dāng)形式填空。*Thisis_______(I)book._______(you)isonthedesk.*—Isthis_______(she)ruler?—No,_______(she)isblue.Thisis_______(he).*Theseare_______(we)bags._______(they)areblack.2.單項(xiàng)選擇。*—Whosepenisthis?—It's_______.A.myB.mineC.ID.me*Thisisnot_______kite._______isred.A.her;HerB.hers;HerC.her;HersD.hers;Hers六、一般現(xiàn)在時(shí)要點(diǎn)點(diǎn)撥：一般現(xiàn)在時(shí)是英語(yǔ)中最基本的時(shí)態(tài)之一，表示經(jīng)常性、習(xí)慣性的動(dòng)作或存在的狀態(tài)。當(dāng)主語(yǔ)是第三人稱(chēng)單數(shù)（he,she,it或單個(gè)的人/物）時(shí)，謂語(yǔ)動(dòng)詞要用第三人稱(chēng)單數(shù)形式，通常是在動(dòng)詞原形后加-s或-es（如like-likes,go-goes,watch-watches）。其否定形式和疑問(wèn)形式要借助助動(dòng)詞do/does。實(shí)戰(zhàn)演練1.用括號(hào)內(nèi)所給動(dòng)詞的適當(dāng)形式填空。*Tomoften_______(play)footballafterschool.*I_______(get)upatsixeverymorning.*She_______(notlike)bananas.*_______yourfather_______(read)newspaperseveryday?2.句型轉(zhuǎn)換。*TheyplaybasketballonSundays.(改為否定句)They______________basketballonSundays.*HewatchesTVintheevening.(改為一般疑問(wèn)句，并作否定回答)_______he_______TVintheevening?No,he_______.參考答案與解析（部分典型題）一、名詞的數(shù)與格1.books,feet,sister's,teachers'(解析：book的復(fù)數(shù)直接加s；foot的復(fù)數(shù)是不規(guī)則變化feet；單數(shù)名詞的所有格加's；以s結(jié)尾的復(fù)數(shù)名詞所有格只加')2.C(children是child的復(fù)數(shù)),C(LucyandLily's表示兩人共有的)二、be動(dòng)詞的用法1.am,is;are,are;Is,is;were,are(解析：最后一句yesterday提示用過(guò)去式were，now提示用are)2.Tomisn'tintheclassroom.IsTomintheclassroom?Yes,heis.No,heisn't.三、情態(tài)動(dòng)詞can的用法1.can,can't;Can,can;can2.cansing,dance;can'tplay四、指示代詞1.C;B;C2.these,They;those,They(解析：回答these/those用they)五、物主代詞1.my,Yours;her,hers,his(或hispen)2.B;C(解析：第一空后無(wú)名詞，用名詞性物主代詞mine；第二空后無(wú)名詞，用名詞性物主代詞hers)六、一般現(xiàn)在時(shí)1.plays(Tom是三單);get(I非三單);doesn'tlike(she是三單，否定用doesn't+原形);Does,read(your
