七年級上冊英語語法及練習(xí)

七年級上冊英語語法及練習(xí)1．動詞be（is,am,are）的用法我(I)用am,你(you)用are,is跟著他(he),她(she),它(it)。單數(shù)名詞用is,復(fù)數(shù)名詞全用are。變否定,更容易,be后not加上去。變疑問,往前提,句末問號莫丟棄。還有一條須注意,句首大寫莫忘記。2．this,that和it用法(1)this和that是指示代詞,it是人稱代詞。(2)距離說話人近的人或物用this,距離說話人遠的人或物用that。如：Thisisaflower.這是一朵花。(近處)Thatisatree.那是一棵樹。(遠處)(3)放在一起的兩樣?xùn)|西,先說this,后說that。如：Thisisapen.Thatisapencil.這是一支鋼筆。那是一支鉛筆。(4)向別人介紹某人時說Thisis…,不說Thatis…。如：ThisisHelen.Helen,thisisTom.這是海倫,海倫,這是湯姆。(5)Thisis不能縮寫,而Thatis可以縮寫。如：Thisisabike.That’sacar.這是一輛自行車。那是一輛轎車。(6)打電話時,介紹自己用this,詢問對方用that。如：—Hello!IsthatMissGreen?喂,是格林小姐嗎？—Yes,thisis.Who’sthat?是的,我是,你是誰？注意：雖然漢語中使用“我”和“你”,但英語中打電話時絕不可以說：Iam…,Areyou…？/Whoareyou?(7)在回答this或that作主語的疑問句時,要用it代替this或that。如：①—Isthisanotebook?這是筆記本嗎？—Yes,itis.是的,它是。②—What’sthat?那是什么？—It’sakite.是只風(fēng)箏。3．these和those用法this,that,these和those是指示代詞,these是this的復(fù)數(shù)形式,指時間,距離較近的或下面要提到的人或事;those是that的復(fù)數(shù)形式,指時間、距離較遠或前面已經(jīng)提到過的人或事物。①Thisismybed.ThatisLily’sbed.這是我的床。那是莉莉的床。②Thesepicturesaregood.那些畫很好。③Arethoseappletrees?那些是蘋果樹嗎？在回答主語是these或those的疑問句時,通常用they代替these或those以避免重復(fù)。如：④Arethese/thoseyourapples?這些(那些)是你的蘋果嗎？Yes,theyare.是的,他們是。4．名詞＋’s所有格單數(shù)名詞后直接加“’s”：Jim’scoat吉姆的外套Jeff’smother杰夫的媽媽以s結(jié)尾的復(fù)數(shù)名詞,只加“’”Teachers’Day教師節(jié)thetwins’books雙胞胎的書不以s結(jié)尾的不規(guī)則的名詞復(fù)數(shù),加“’s”Children’sDay兒童節(jié)men’sshoes男式鞋表示兩者共同擁有時,只在最后一個名詞后加’sLucyandLily’smother露茜和莉莉的媽媽(共同的媽媽,一個媽媽)表示兩者各自擁有時,要在每個名詞后加’sLucy’sandKate’srooms露茜和凱特的房間（各自的房間,兩間房子）5．Therebe句型(1)Therebe句型主要用以表達“某處（某時）有某人（某物）?！逼浠窘Y(jié)構(gòu)為“Therebe＋某物（某人）＋某地（某時）”其中there是引導(dǎo)詞,沒有詞義；主語是be后面的名詞,be是謂語動詞,在一般現(xiàn)在時中be只用is和are兩種形式。下面這首歌訣可幫你巧記therebe句型結(jié)構(gòu)：Therebe放句首,主語跟在后。地、時放句末,強調(diào)置前頭。如：Thereisabookonthedesk.有時為了強調(diào)地點,也可把介詞短語放在句首。如：Onthedeskthereisabook.(2)Therebe句型中的be動詞如何確定呢？請先看看下面這首歌訣：Be動詞,有三個,am,is還有are?！癟herebe”真特別,不留am只留倆,那就是is還有are。要用is還是are,須看其后的名詞是單數(shù)還是復(fù)數(shù)。若是單數(shù)或不可數(shù)名詞用is,否則就用are。如：①Thereisatreebehindthehouse.②Thereissomewater（水）inthebottle（瓶子）.③Therearesomepearsinthebox.(3)注意：如果“be”后的主語是由and連接的兩個或兩個以上的名詞,那么be的形式要遵循“遠親不如近鄰”的原則。也就是說,“be”的形式是由與它最近的那個名詞來確定的。若那個名詞是單數(shù)或不可數(shù)名詞要用is,是復(fù)數(shù)就用are。如：①Thereisabookandsomepensonthefloor.②Therearesomepensandabookonthefloor.6．like一詞的用法like用作及物動詞,譯為“喜歡”。(1)后接名詞或代詞,表示喜歡某人或某物。如：Ilikethebabyverymuch.我非常喜歡這個小孩。(2)后接動名詞(v.-ing),表示“喜歡做某事”,著重于習(xí)慣、愛好。如：Tomlikesplayingfootball.湯姆喜歡踢足球。(3)后接動詞不定式(todo),表示“偶爾地喜歡做某事”,著重于某次具體的行為。如：Ilikereading,butIliketowatchTVthisevening.我喜歡讀書,但我今晚想看電視。7．句子單數(shù)變復(fù)數(shù),注意以下五要素(1)主格人稱代詞要變成相應(yīng)的復(fù)數(shù)主格人稱代詞,即I→we,you→you,she,he,it→they。如：Sheisagirl.→Theyaregirls.(2)am,is要變?yōu)閍re。如：I’mastudent.→Wearestudents.(3)不定冠詞a,an要去掉。如：Heisaboy.→Theyareboys.(4)普通單數(shù)名詞要變?yōu)閺?fù)數(shù)形式。如：Itisanapple.→Theyareapples.(5)指示代詞this,that要變?yōu)閠hese,those。如：Thisisabox.→Theseareboxes.8．英語日期的表示法英語中月份和星期名稱都是專有名詞,它們的首字母必須大寫,并且前面無需用冠詞。用英語表示日期,其順序為月+日+年,日和年之間需用逗號隔開。如：August2nd,2003(2003年8月2日)。也可以用日+月+年來表示。如：10thMay,2003(2003年5月10日)英語日期前介詞的使用：若指在哪一年或哪一月,則用介詞in,若具體到某一天,則需用介詞on。1月January2月February3月March4月April5月May6月June7月July8月Aguest9月September10月October11月November12月DecemberSunday,星期天Monday,星期一Tuesday,星期二Wednesday,星期三Thursday,星期四Friday,星期五Saturday,星期六9.時間的表達法(1)直讀式,即直接讀出時間數(shù)字7:05sevenfive8:16eightsixteen(2)過、差式,即幾點差幾分,幾點過幾分。（以30分為分界線）1:25twenty-fivepastone2:30halfpasttwo3:43seventeentofour4:38twenty-twotofive(3)12小時制6:00a.m.上午6點8:20p.m.下午8點20分(4)24小時制13:0013點鐘22:1522點15分(5)15分可用quarter4:15aquarterpastfour5:45aquartertosix(6)時間前通常用at.at5o’clockat7:30p.m.10.want用法(1)想干什么用wanttodosthTheywanttojointhesportsclub.他們想加入運動俱樂部。(2)第三人稱單數(shù)作主語,want要作變化①Hewantstoplaybasketball.②LiXiawantstoplaythepiano.(3)變疑問句,否定句要借助助動詞do或does.①－Doyouwanttoplaysoccerball?－Yes,Ido./No,Idon’t.②－Doeshewanttogohomebybus?－Yes,hedoes./No,hedoesn’tI.be動詞(用be動詞的正確形式填空)1._______yourgrandmotherthinorchubby?2.
