七年級英語語法重點(diǎn)鞏固練習(xí)親愛的同學(xué)們，七年級是英語學(xué)習(xí)打基礎(chǔ)的關(guān)鍵時(shí)期，而語法則是構(gòu)建這座語言大廈的重要基石。扎實(shí)掌握語法知識，不僅能幫助我們更準(zhǔn)確地理解和運(yùn)用英語，也能為未來的學(xué)習(xí)鋪平道路。這份鞏固練習(xí)旨在回顧我們本學(xué)期學(xué)過的核心語法點(diǎn)，希望大家能認(rèn)真對待，通過練習(xí)查漏補(bǔ)缺，真正做到學(xué)以致用。一、代詞(Pronouns)代詞是我們?nèi)粘＝涣髦蓄l繁使用的詞類，它能避免名詞的重復(fù)，讓表達(dá)更簡潔。核心回顧：*人稱代詞：分為主格(I,you,he,she,it,we,you,they)和賓格(me,you,him,her,it,us,you,them)。主格通常作句子的主語，賓格則作動(dòng)詞或介詞的賓語。*物主代詞：分為形容詞性物主代詞(my,your,his,her,its,our,your,their)和名詞性物主代詞(mine,yours,his,hers,its,ours,yours,theirs)。形容詞性物主代詞后需跟名詞，名詞性物主代詞可獨(dú)立使用，相當(dāng)于“形容詞性物主代詞+名詞”。鞏固練習(xí)：1.Thisisnotmybook.______(I)isonthedesk.2.Myparentsareteachers.______(They)workinamiddleschool.3.Couldyoupleasepass______(I)thepen?It'sonyourleft.4.—Isthisredbag______(you)?—No,itisn't.______(I)isblue.5.Lookatthecat.______(It)tailisverylong.二、Be動(dòng)詞的用法(TheVerb"Be")Be動(dòng)詞是英語中最基礎(chǔ)也最常用的動(dòng)詞之一，它的形式會(huì)根據(jù)主語和時(shí)態(tài)發(fā)生變化。核心回顧：*一般現(xiàn)在時(shí)中，be動(dòng)詞有三種形式：am,is,are。*I用am。*He,She,It及單數(shù)名詞用is。*You,We,They及復(fù)數(shù)名詞用are。*其否定形式是在后面加not(isnot=isn't,arenot=aren't,amnot無縮寫)。*一般疑問句是將be動(dòng)詞提到句首。鞏固練習(xí)：1.Mybrother______(be)astudent.He______(benot)ateacher.2.______(be)youfromBeijing?Yes,I______.3.Thebooks______(be)ontheshelf.Where______(be)thepen?4.—______(be)thisyourruler?—No,it______.It______(be)Tom's.5.We______(be)goodfriends.They______(be)inthesameclass,too.三、名詞的單復(fù)數(shù)(SingularandPluralNouns)名詞有單數(shù)和復(fù)數(shù)之分，表示一個(gè)人或事物用單數(shù)，表示兩個(gè)或更多用復(fù)數(shù)。核心回顧：*規(guī)則變化：*一般情況下加-s(e.g.,book→books)。*以s,x,ch,sh結(jié)尾的加-es(e.g.,bus→buses,box→boxes)。*以輔音字母+y結(jié)尾的，變y為i再加-es(e.g.,baby→babies)。*以f/fe結(jié)尾的，變f/fe為v再加-es(e.g.,knife→knives,leaf→leaves)(部分特殊)。*不規(guī)則變化：需要特殊記憶(e.g.,man→men,child→children,foot→feet,mouse→mice,sheep→sheep,fish→fish)。鞏固練習(xí)：1.Therearethree______(boy)intheplayground.2.Ihavetwo______(knife)andsome______(tomato).3.Howmany______(class)arethereinyourgrade?4.Lookatthose______(woman).Theyare______(teacher).5.Helikeseating______(potato)and______(fish).四、情態(tài)動(dòng)詞can/may/must(ModalVerbs)情態(tài)動(dòng)詞表示說話人的語氣或情態(tài)，如能力、許可、必須等。它們后面跟動(dòng)詞原形。核心回顧：*can:表示“能，會(huì)”（能力）或“可以”（許可，口語中）。否定can't/cannot。*may:表示“可以”（許可，較正式）或“可能”（推測）。否定maynot。*must:表示“必須，一定”（義務(wù)或肯定推測）。否定mustn't(禁止)/needn't(不必)。鞏固練習(xí)：1.I______(can)swim,butI______(cannot)fly.2.______(may)Iborrowyourdictionary?Sure,hereyouare.3.You______(must)bequietinthelibrary.You______(mustnot)talkloudly.4.—______(can)heplaythepiano?—Yes,he______.He______(play)verywell.5.We______(must)finishourhomeworkontime.五、介詞(Prepositions)介詞用于表示名詞或代詞與句中其他詞的關(guān)系，如時(shí)間、地點(diǎn)、方向等。核心回顧：*時(shí)間介詞：at(具體時(shí)刻,節(jié)日)，in(年,月,季節(jié),泛指上午/下午/晚上)，on(具體某一天,具體某一天的上午/下午/晚上)。*地點(diǎn)介詞：in(在…里面/大地方)，on(在…上面,接壤)，under(在…下面)，behind(在…后面)，beside(在…旁邊)，between(在…兩者之間)，near(在…附近)。*其他常用介詞：with(和…一起,用某種工具)，for(為了,給)，from(來自)，about(關(guān)于)。鞏固練習(xí)：1.WehaveEnglishclass______9:00______themorning.2.Mybirthdayis______July5th.Iusuallygetpresents______myparents.3.Thecatis______thechair.Theballis______thechair,sothecatcan'tseeit.4.Ioftengotoschool______foot,butsometimes______bike.5.Thereisamap______China______thewall.六、一般現(xiàn)在時(shí)(SimplePresentTense)一般現(xiàn)在時(shí)表示經(jīng)常性、習(xí)慣性的動(dòng)作或狀態(tài)，或客觀真理。核心回顧：*動(dòng)詞形式：*主語是第一人稱(I,we)、第二人稱(you)、第三人稱復(fù)數(shù)(they)及復(fù)數(shù)名詞時(shí)，用動(dòng)詞原形。*主語是第三人稱單數(shù)(he,she,it)及單數(shù)名詞時(shí)，動(dòng)詞要加-s或-es(規(guī)則類似名詞復(fù)數(shù))。*標(biāo)志性時(shí)間狀語：often,usually,always,sometimes,everyday/week/month/year,onSundays等。*否定句和疑問句通常借助助動(dòng)詞do/does(第三人稱單數(shù)用does)。鞏固練習(xí)：1.Tomusually______(get)upat6:30inthemorning.2.Myparents______(watch)TVeveryevening.3.She______(notlike)playingbasketball.She______(like)swimming.4.______yourbrother______(go)toschoolbybus?5.Theearth______(go)aroundthesun.七、現(xiàn)在進(jìn)行時(shí)(PresentContinuousTense)現(xiàn)在進(jìn)行時(shí)表示此時(shí)此刻或現(xiàn)階段正在進(jìn)行的動(dòng)作。核心回顧：*構(gòu)成：be動(dòng)詞(am,is,are)+動(dòng)詞的現(xiàn)在分詞(V-ing)。*動(dòng)詞現(xiàn)在分詞構(gòu)成：*一般加-ing(e.g.,play→playing)。*以不發(fā)音的e結(jié)尾的，去e加-ing(e.g.,make→making)。*重讀閉音節(jié)結(jié)尾，且末尾只有一個(gè)輔音字母的，雙寫這個(gè)輔音字母再加-ing(e.g.,run→running,swim→swimming)。*標(biāo)志性時(shí)間狀語：now,look,listen,atthemoment等。鞏固練習(xí)：1.Listen!Someone______(sing)inthenextroom.2.I______(do)myhomeworknow.I______(notplay)games.3.What______they______(do)overthere?They______(play)football.4.Look!Thebird______(fly)inthesky.5.Mymother______(cook)dinnerinthekitchenatthemoment.---參考答案（請同學(xué)們先獨(dú)立完成，再對照答案檢查哦！）一、代詞1.Mine2.They3.me4.yours,Mine5.Its二、Be動(dòng)詞的用法1.is,isn't/isnot2.Are,am3.are,is4.Is,isn't/isnot,is5.are,are三、名詞的單復(fù)數(shù)1.boys2.knives,tomatoes3.classes4.women,teachers5.potatoes,fish(或fishes,指不同種類的魚時(shí))四、情態(tài)動(dòng)詞can/may/must1.can,can't/cannot2.May3.must,mustn't4.Can,can,plays5.must五、介詞1.at,in2.on,from3.on,under(答案不唯一，合理即可，如：beside,behind)4.on,by
