初一英語(yǔ)語(yǔ)法總結(jié)
一、初一英語(yǔ)語(yǔ)法詞法
初一英語(yǔ)語(yǔ)法雖然是從簡(jiǎn)單的一些日常用語(yǔ)出發(fā)的,但語(yǔ)法中常會(huì)有一些知識(shí)點(diǎn)看起來很細(xì)小,容易被忽視,但這些知識(shí)點(diǎn)掌握不熟練,往往會(huì)造成一些語(yǔ)法應(yīng)用上的錯(cuò)誤。因此在學(xué)習(xí)初一英語(yǔ)語(yǔ)法時(shí),要認(rèn)真、細(xì)心,不要覺得一些地方不重要而得過且過。下面從幾個(gè)方面,總結(jié)出了初一英語(yǔ)語(yǔ)法,如果要復(fù)習(xí)英語(yǔ)句法的同學(xué),可以參考一下今天講的內(nèi)容1、名詞A)、名詞的數(shù)
我們知道名詞可以分為可數(shù)名詞和不可數(shù)名詞,而不可數(shù)名詞它沒有復(fù)數(shù)形式,但可數(shù)名詞卻有單數(shù)和復(fù)數(shù)之分,復(fù)數(shù)的構(gòu)成如下:
一)在后面加s。如:fathers,books,Americans,Germans,apples,bananas二)x,sh,ch,s,tch后加es。如:boxes,glasses,dresses,watches,wishes,faxes
三)1)以輔音字母加y結(jié)尾的變y為i再加es如:baby-babies,family-families,duty-duties,comedy-comedies,documentary-documentaries,story-stories
2)以元音字母加y結(jié)尾的直接加s。如:day-days,boy-boys,toy-toys,key-keys,ways四)以o結(jié)尾加(s外來詞)。如:radios,photos,但如是輔音加o的加es:如:tomatoes西紅柿,potatoes馬鈴薯
五)以f或fe結(jié)尾的變f為v再加es(s)。如:knife-knives,wife-wives,half-halves,shelf-shelves,leaf-leaves,yourself-yourselves
六)單復(fù)數(shù)相同(不變的)有:fish,sheep,deer鹿子,Chinese,Japanese
七)一般只有復(fù)數(shù),沒有單數(shù)的有:people,pants,shorts,shoes,glasses,gloves,clothes,socks
八)單詞形式不變,既可以是單數(shù)也可以是復(fù)數(shù)的有:police警察局,警察,class班,同學(xué),family家,家庭成員
九)合成的復(fù)數(shù)一般只加主要名詞,多數(shù)為后一個(gè)單詞。如:actionmovie-actionmovies,penpal-penpals;但如果是由man或woman所組成的合成詞的復(fù)數(shù)則同時(shí)為復(fù)數(shù)。如:mandoctor-mendoctors,womanteacher-womenteachers
十)有的單復(fù)數(shù)意思不同。如:fish魚fishes魚的種類,paper紙papers報(bào)紙,卷子,論文,work工作works作品,工廠,glass玻璃glasses玻璃杯,眼鏡,orange桔子水oranges橙子,light光線lights燈,people人peoples民族,time時(shí)間times時(shí)代,次數(shù),chicken雞肉chickens小雞
十一)單個(gè)字母的復(fù)數(shù)可以有兩種形式直接加s或’s。如:Is(I’s),Ks(K’s)。但如是縮略詞則只加s。如:IDs,VCDs,SARs
十二)特殊形式的有:child-children,man-men,woman-women,foot-feet,mouse-mice,policeman-policemen,Englishman-EnglishmenB)名詞的格
當(dāng)我們要表示某人的什么東西或人時(shí),我們就要使用所有格形式。構(gòu)成如下:一)單數(shù)在后面加’s。如:brother’s,Mike’s,teacher’s
二)復(fù)數(shù)以s結(jié)尾的直接在s后加’,如果不是以s結(jié)尾的與單數(shù)一樣處理。如:Teachers’Day教師節(jié),classmates’;Children’sDay六一節(jié),Women’sDay婦女節(jié)
三)由and并列的名詞所有時(shí),如果是共同所有同一人或物時(shí),只加最后一個(gè)’s,但分別擁有時(shí)卻分別按單數(shù)形式處理。如:MikeandBen’sroom邁克和本的房間(共住一間),Mike’sandBen’srooms邁克和本的房間(各自的房間)2、代詞
