㈡ 八年級上英語語法歸納,有嗎
語法專項
I. 名詞:在我們身邊存在著形形色色的人和事物,它們都有自己的稱呼,我們用來稱呼它們的詞就是名詞,概括來說表示人、事物、地方、現象等的名稱的詞都叫名詞。
一. 名詞的種類:名詞可以分為專有名詞和普通名詞,普通名詞又分為個體名詞和集體名詞,物質名詞和抽象名詞。
1. 專有名詞:專有名詞是指人、地方、團體、機構等特有的名詞,它的第一個字母必須大寫,專有名詞前一般不加冠詞。
A. 表示人名:Li Bai,Mr Black,Doctor Zhang
B. 表示地名:China,London,Zhong Guan Cun Street.
C. 由普通名詞構成的專有名詞:the Spring Festival, the Palace Museum.
2. 普通名詞:普通名詞指一類人或東西或一個抽象的名標,它可以進一步分為個體名詞、集合名詞、物質名詞和抽象名詞四類。
A. 個體名詞:表示某類人或事物中的個體:student,teacher,car.
B. 集合名詞:表示若干個體組成的集合體;family,police,people.
C. 抽象名詞:表示動作、狀態、品質、感情等抽象的概念:music,love
D. 物質名詞:表示無法分為個體的物質或實物:water,tea,air

1. 單數可數名詞,表示「一」的概念,要用名詞的單數形式,表示名詞的單數,要在名詞前加冠詞a或an。 eg:a book, a tree, a shark an octopus,an apple,an egg
2. 復數可數名詞:在夢塔英語中,如果要表示「二、三、四,……」概念時,要用名詞的復數形式,名詞的復數形式是在單數名詞後加上詞尾-s或-es構成的。
A. 名詞復數的規則變化。 a. 在一般情況下,詞尾後加-s。 books,cups,beds,boys,horses
b. 以s,x,sh,ch結尾的詞,詞尾加-es,讀|iz| buses,boxes,dishes,watches

3. 不可數名詞表示量的概念時,在這些詞前加上數量詞。 eg:a cup of coffee,a piece of paper,three slices of bread
II. 不定代詞,我們所學的不定代詞有all,both,each,every,some,any,many,much,(a)few,(a)little,either,neither,other,another,no,none以及含有some-,any-,no-等的合成代詞,這些不定代詞大都可以代替名詞和形容詞,在句中作主語、賓語、表語和定語。
一. some,any及其合成詞的用法。
1. 基本用法 some,any可與單、復數和不可數名詞連用。 some用於肯定句中,而不能用於疑問句中,any一般用於否定句,疑問句和條件句中。 eg:I have some interesting books. There is some yogurt in the bottle. I don't have any money. Were there any sharks in the aquarium?
2. 特殊用法 在疑問句中,一般不用some,只有當問句表示一種邀請或者請求,或期待一個肯定的回答時才能用some。 eg:Would you like some more tea?
二. all,both的用法 1. all代表或修飾四個以上的人或事物,或不可數的東西。 eg:We all like eat potato chips. All the students in our class went to the zoo. 2. both是指「兩者都……」 eg:The twins both have long hair. There are many trees on both sides of the street.
三. many,much,(a lot),a few,few,a little,little。這些詞都可以表示數量,並且都可以修飾名詞。 1. many,a lot,a few,few修飾可數名詞;much,a lot,a little,little修飾不可數名詞。 2. many,much,a lot,a few,a little表示肯定的意思:few,little表示否定的意思。 eg:How much relish do we need? There are a few minutes left, aren't there? There is a little time left, is there?
III. 形容詞的比較等級:夢塔英語中的形容詞,在表示「比較——」和「最——」這樣的概念時,要用特別的形式,稱為比較級和最高級。 原級 比較級 最高級 young(年輕) younger(比較年輕) youngest(最年輕)
一. 變化形式如下:
1. 規則變化 構成法 原級 比較級 最高級 一般單音節詞和部分雙音節詞在詞尾加-er〔 〕(比較級)和-est〔ist〕(最高級) 以不發音的e結尾的單音節詞和少數以le結尾的雙音節詞只在詞尾加-r(比較級)和-st(最高級) 「輔音字母+y」結尾的雙音節詞,將詞尾的y改為i,再加-er和-est 重讀閉音節詞,只有一個輔音字母結尾時,要雙寫該輔音字母,再加-er,-est 部分雙音節詞和多音節詞,在該詞前面加more和the most構成比較級和最高級 tall高的(adj.) great巨大的(adj.) fast快(adj.& adv.) near附近的(adj. & adv.) nice好的(adj.) large大的(adj.) able有能力的(adj.) late晚,晚的(adj. & adv.) easy容易的(adj.) busy忙的(adj.) early早(adj. & adv.) big大的(adj.) hot熱的(adj.) thin細的,瘦的(adj.) important重要的(adj.) beautiful漂亮的(adj.) slowly慢(adv.) quickly快(adv.) teller greater faster nearer nicer larger abler later easier busier earlier bigger hotter thinner more important more beautiful more slowly more quickly the tallest the greatest (the)fastest (the)nearest the nicest the largest the ablest (the)latest the easiest the busiest (the)earliest the biggest the hottest the thinnest the most important the most beautiful (the) most slowly (the) most quickly
2. 不規則變化 原級 比較級 最高級 good好的(adj.) well健康的(adj.) 好(adv.) bad壞的(adj.) ill有病的(adj.) badly壞(adv.) many多(adj. & adv.) much多(adj. & adv.) far遠(adj. & adv.) little少(adj. & adv.) old老的(adj.) late遲的,晚的(adj.) better['bet ]較好的(地) worse[w :s]更壞(地) 更差(地) more[m :]更多的,更加 farther['fa: ]較遠 further['f : ]進一步 less[les]較少的(地) older[' uld ]較老的 elder['eld ]年長的 later較遲的,較近的 latter['l t ]後者 (the) best[best]最好的(地) (the) worst[w :st]最壞(地) 最糟(地) (the) most[m ust]最多的(地) (the) farthest['fa: ist]最遠的(地) (the) furthest['f : ist]最深遠的(地) (the) least[li:st]最少的(地) the oldest[' uldist]最老的 the eldest['eldist]最年長的 the latest(時間上)最近的 the last(順序)最後的 比較: elder和eldest主要用於表示家庭成員之間的長幼關系,如:elder sister姐姐。 older和oldest則用於表示年齡大小。 They are in the same age, but Li looks much older than Ma. 他們兩個在年齡上一般大,但看起來李比馬老的多。 二. 形容詞比較等級的用法。 形容詞比較等級通常分為原形,比較級和最高級三種基本形式,具體而言,它們分別以下列形式出現在句中: (1)as +原形+ as 表示「……和……相同」。 (2)比較級+ than 表示「……比……較為……」。 (3)the +最高級+ of / in 表示「在……中最為……」。 eg:My dog is as old as that one. The jacket is as cheap as that old one. Is he as busy as before? Mary is funnier than Jane. His brother is younger than me. Tom is the happiest of us all. Spring is the best season of the year. 三. 需要注意的一些問題。 1. 在形容詞比較級前還可以用much,even,far,a lot,still,a little來修飾,表示「……的多」,「甚至……」,「仍然,還……」,「更……」,以加強語氣。 eg:Our city is much more beautiful than yours. Japan is a little larger than Germany.
2. 表示「大幾歲」,「高……」等,句型用「表示數量的詞+形容詞比較級。」 eg:I'm two years older than you. She is a head taller than me.
3. 表示「越來越……」,句型用「比較級+ and +比較級」。 eg:China is more and more beautiful. The earth is getting warmer and warmer.
4. 表示「是最……之一」句型用「one of the +形容詞最高級」。 eg:Beijing is one of the busiest cities in China. One of the most important languages is English.
㈢ 八年級英語語法大全
可數名詞與不可數名詞一.可數名詞英語中的物質名詞大體上可分為可數名詞「最……」見課本p93語法 the +最高級 She is the tallest of all her
㈣ 大蝦們 八年級英語的重點語法有哪些
1.一般過去時態.這一時態在七年級已經接觸過,八年級算復習吧.表示過去某一時間點或時間段發生的事情.謂語動詞分實義動詞和be動詞兩種.
(1)I studied Japenese for two years.
(2) I was a student one year ago,but now I am a teacher.
2.過去進行時態.結構:was/were +V-ing ,表示過去某一時間點或時間段正在進行的事情.
eg.I was sleeping when the phone rang.
3.一般將來時態.結構:will+V,表示將來某一時間將要發生的事情.
eg.I will go back home in three months.
4.現在完成進行時態.結構:have/has+been +Ving,表示某一行為從過去某一時間點開始,一直延續到現在,並有可能繼續進行下去.
eg.I have been teaching English in this scool for two years.
5.現在完成時態.結構:have/has +done(動詞過去分詞,需要記憶),表示一動作從過去開始,延續到現在,並且已經完成.強調這一事情對現在造成的影響.
eg.I have finished my homework.
基本上就這些了.你剛剛提到的過去式和現在進行時是七年級的語法點,八年級會予以鞏固並加大難度.
建議上課的時候注意聽老師講,重在理解,而後多背一些例句,並能進行應用.
英語是一個慢慢累積的過程,慢慢來.祝進步.

㈥ 初中八年級英語所有語法
現在完成時
1.構成
現在完成時是由助動詞 have(has)+動詞的過去分詞構成。助動詞說明該謂語是屬於現在時范圍。它和主語的人稱、數要保持一致。過去分詞是主要的謂語動詞,說明句子的意義。
2.用法
(1)表示動作發生在過去某個不確定的時間,但對現在留下了某種影響和結果。常被just, already, yet 等副詞修飾。常與非延續性動詞連用。 如:
-Have you had lunch yet? -Yes, I have. I've just had it. 你(已經)吃午飯了嗎? 我剛剛吃過。(現在我不餓了)
(2)表示從過去某一時刻開始一直持續到現在的動作或狀態。這個動作可能剛停止,可能仍然在進行。常用延續性動詞,常帶有for和since(自從)等表示一段時間的狀語。
如:He has taught here since 1981. 他自1981年就在這兒教書。(可能還要繼續教)
I haven't seen her for four years. 我有四年沒見到她了。
(3)表示說話前發生過一次或多次的動作,現在成為一種經驗,一般譯為漢語「過」,常帶有twice, ever, never, three times等時間狀語。
如: I have been to Beijing twice. 我去過北京二次。
3.結構
1)陳述句結構:主語+have( has)(not)+過去分詞+其它。have not=haven』t has not= hasn』t.
2) 一般疑問句結構:Have( Has )+主語+過去分詞+其它?
3) 特殊疑問句:特殊疑問詞+have(has) +主語+ 過去分詞+其它?
e.g. He has already finished his homework.
He hasn』t finished his homework yet.
Has he finished his homework yet? --Yes, he has. / No, he hasn』t. / No, not yet.
4.現在完成時的時間狀語
1)現在完成時屬於現在時范圍,故不能和過去的時間狀語連用。如: yesterday, last Sunday, in1990, three years ago等。但是,在強調動作產生的後果和影響時,可以和一些表示不確定的時間狀語連用。
a. 用副詞already和yet。already一般用於肯定句中,yet一般用於否定句和 疑問句中。如:We have already finished our homework.我們已完成作業了。
They haven't finished their homework yet.他們還沒有完成作業。
b. 用ever 和never。多用於否定或疑問句中,表示「曾經」或「從未「等。 如:-Have you ever been to the Great Wall?你曾經去過長城嗎?
-I have never been to the Great Wall.我從未去過長城。 c. 用表示到說話為止的過去時間狀語,如just(剛剛), before(以前), up to now(直到現在)/ until now, in the past (few years/ three days 等), so far (迄今為止) recently 等。 例如:I have seen her before, but I can not remember where. 我以前見過她,但記不起在哪裡見過。
He has been there three times the last few days. 近幾年他去過那裡三次了。 d.用包括「現在」在內的時間狀語,如:today, this morning (month ,year, term等.例如:-Have you met him today? - No, I haven't. 今天你見過他嗎?我沒有。
How many times have you been there this year? 今年你去過那裡多少次?
2) 現在完成時可以和帶有since或for等表示「一段時間」的狀語連用,表示動作或狀態從某一時刻開始,一直持續到現在。如:I haven't seen him for two years. 但是,像come, arrive, buy等終止性動詞不能與表示「一段時間」的狀語連用。要用,必須改為「be(在)」等延續性動詞來表述。現歸納總結一下由非延續性動詞到延續性動詞的轉換:
arrive → be here begin (start) → be on die →be dead come back → be back leave → be away fall ill (sick, asleep) → be ill (sick, asleep) go out →be out finish →be over put on →wear 或be on get up →be up join →be in / be a member of… open → be open close →be closed go to school→ be a student borrow →keep buy →have catch(a cold)→ have(a cold) get to know →know begin to study → study come to work→ work
如:He has been a soldier for three years.他參軍三年了。或He has been in the army for there years. 不可以說He has joined the army for there years.
His father has been dead for two years.他父親去世二年了。(不可以說has died)
The film has been on for ten minutes.電影已開始十分鍾了。(不可以說has begun)
We have studied English for three years. (不可以說have begun) 我們(開始)學英語已三年了。
5. 現在完成時和一般過去時的區別
現在完成時和一般過去時都表示在過去完成的動作。但現在完成時強調的是這一動作與現在的關系。如對現在產生的結果或影響等,而一般過去時只表示動作在過去某一時刻發生,不表示和現在的關系。試比較:
I have lost my new book. 我把新書丟了。(現在還未找到)
I lost my new book yesterday. 我昨天把新書丟了。(昨天丟的,現在找到與否沒說明)
6.幾點注意事項 (1)have been(to)與have gone( to)的區別:have been(to) 表示「去過某地(現在已經回來了)」,可用於各人稱;have gone(to) 表示「去某地了(說話時某人不在當地)」,常用於第 三人稱,前者可與once ,never, several times等連用,後者則不能。如:They have been to Beijing twice.他們去過北京兩次。 He has gone to Beijing . 他去北京了。 (2)「It is或has been + 一段時間+ since引導的時間狀語從句」表示「某人干某事已經多長時間了」。since從句的謂語要用非延續性動詞 若動詞延續,則譯成相反的意思。如:It is two years since his father died. =His father has been dead for two years.他父親去世已有三年了。 It is two years since his father lived here. 他爸爸不住這兒已有三年了。 (3)終止性動詞現在完成時的否定式,已變成一種可以延續的狀態,因此可以和表示一段時間的狀語連用。如:I haven't left here since 1997.自從1997年以來,我一直沒有離開過這兒。 (4).提問for短語或since狀語用how long。
(5).完成時的否定形式與比較級連用表達最高級含義。如:
I have never seen a better film.我從未看過一部更好的電影。(這部最好)
註:否定式與比較級連用表示最高級含義不一定用於完成時態。如:
--- What about going fishing? --- I can』t agree more.(我再同意不過了哦)
.語法—直接引語變間接引語(多數情況下變為賓語 從句)
(1). 直接引語如果是陳述句,變為間接引語時,用連詞that 引導(口語中可以省略引導詞)賓語從句。把下列句子變為間接引語或直接引語:

㈧ 八年級英語需要掌握的語法有那些
一、詞法

A)、名詞的數
我們知道名詞可以分為可數名詞和不可數名詞,而不可數名詞它沒有復數形式,但可數名詞卻有單數和復數之分,復數的構成如下:
