    誰有初一英語上冊重要語法知識小結?
    英語人氣:356 ℃時間:2019-08-17 16:53:08
    優(yōu)質(zhì)解答
    您說的是哪個版本的教材呀?
    現(xiàn)以仁愛版七年級上冊為例:
    一、48個國際音標及26個英文字母的正確書寫
    要熟練掌握元音和輔音,5個元音字母(a, e, i, o, u),字母的正確占格及單詞間距.
    二、be動詞的用法
    be動詞有三種變形,分別是:am, is, are.記憶口訣:
    “我”用am, “你”用are, is用于“他、她、它”;單數(shù)全都用is,復數(shù)全部都用are.
    三、人稱及人稱代詞的不同形式(主格和賓格)
    1、三種人稱:第一人稱(I, we),第二人稱(you, you),第三人稱(he, she, it, Maria).
    2、人稱代詞的主格,即人稱代詞位于句子主語位置時的形態(tài):I, We, You, You, He, She, It, Maria.
    3、人稱代詞的賓格,即人稱代詞位于句子賓語位置時的形態(tài):me, us, you, you, him, her, it.
    4、形容詞性物主代詞:my, our, your, your, his, her, its, their.
    5、名詞性物主代詞:mine, ours, yours, yours, his, hers, its, theirs.
    6、反身代詞:myself, ourselves, yourself, yourselves, himself, herself, itself, themselves.
    四、基數(shù)詞(表示數(shù)量多少的詞,大致相當于代數(shù)里的自然數(shù))
    zero, one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty, twenty-one, twenty-two, twenty-three,twenty-four, twenty-five, twenty-six, twenty-seven, twenty-eight, twenty-nine, thirty, forty, fifty, sixty,seventy, eighty, ninety, one hundred,one hundred and one.
    五、一般疑問句及特殊疑問句
    1、一般疑問句:能用Yes或No來回答的問句.一般疑問句句尾讀升調(diào).
    2、特殊疑問句:不能用Yes或No來回答的問句.特殊疑問句句尾讀降調(diào).
    六、可數(shù)名詞變復數(shù)
    可數(shù)名詞變復數(shù)時,有規(guī)則變化和不規(guī)則變化兩種.
    1、規(guī)則變化:
    1)一般情況直接在詞尾加“-s ”,如:cake-cakes, bag-bags, day-days, face-faces, orange-oranges等;
    2)以s, x, sh, ch結尾的詞,要在詞尾加“-es ”,如:bus-buses, watch-watches, box-boxes等;
    3)以輔音字母加y結尾的詞,變y為i再加“-es ”,如:baby-babies, country-countries, family-families等;
    4)部分以f (e)結尾的詞,變f (e)為“ves ”,如:knife-knives, half-halves等;
    5)以o結尾的詞,加“-s ”或“-es ”,如:zoo-zoos, photo-photos, tomato-tomatoes, potato-potatoes等.記憶口訣:除了“英雄”hero外,凡是能吃的,加“-es ”,不能吃的加“-s ”.
    2、不規(guī)則變化:
    1)改變單數(shù)名詞中的元音字母:man-men, woman-women, foot-feet, tooth-teeth等;
    2)單、復同形:sheep-sheep, Chinese-Chinese, Japanese-Japanese等;
    3)其他形式:mouse-mice, child-children等.
    七、簡單句的成分及主謂一致原則
    最基本構成:主語+謂語+賓語,其中謂語由動詞來充當.
    主謂一致原則,就是句子的謂語要始終與主語保持數(shù)量上的一致性.當主語是第三人稱單數(shù)(簡稱“三單”)時,謂語動詞也要相應變成單數(shù)形式;當主語非“三單”時,謂語動詞就用原形.實意動詞變“三單”的規(guī)則如下:
    1)一般動詞在詞尾加“-s ”,如:like-likes, tell-tells, play-plays等;
    2)以字母s, x,ch, sh結尾的動詞加“-es ”,如:guess-guesses, teach-teaches, watch-watches等;
    3)以o結尾的動詞一般加“-es ”,如:do-does, go-goes等;
    4)以輔音字母加y結尾的動詞,先變y為i,再加“-而是”,如:fly-flies, carry-carries等;
    5)have的三單形式是has.
    八、冠詞的用法(名詞前面必須要有冠詞)
    冠詞分為定冠詞(the)和不定冠詞(a, an)兩種.
    1、定冠詞the表示“特指”,可譯為“這個”、“那個”、“這些”、“那些”.
    2、不定冠詞a, an用來表明(可數(shù))名詞的數(shù)量是“一個”.an用于以元音開頭(注意不是以元音字母開頭)的單詞前,a則英語非元音開頭的單詞前.
    3、不定冠詞a, an與基數(shù)詞one的區(qū)別是:不定冠詞不是刻意強調(diào)“數(shù)量”,而基數(shù)詞則強調(diào)“數(shù)量”.
    九、助動詞(do, does )的用法
    只有實意動詞作謂語時才涉及使用助動詞.以like為例:
    1)當句子為肯定句時不涉及使用助動詞,只涉及“主謂一致”原則.
    eg : I like English a lot.
    Michael likes Chinese food very much.
    2)當句子為否定句時,要根據(jù)主語的人稱來決定使用相應的助動詞:當主語為“三單”時,要使用does;當主語為“非三單”時,用助動詞原形do.例如把下列句子變否定句:
    Kangkang likes math.----Kangkang doesn't like math.
    They like sports.------They don't like sports.
    3)當句子變疑問句時,同樣要根據(jù)句子的主語來決定在句首使用Do或Does.例如下列句子變問句:
    Michael likes Chinese Food.----Does Michael like Chinese food?Yes, he does./ No, he doesn't.
    Jane and Helen like music.----Do Jand and Helen like music? Yes, they do./ No, they don't.
    十、名詞所有格
    1、Kangkang's books;Tom and Helen's desk; Ann's and Maria's bikes;
    2、用of表示“.的”,但要從of后往of前翻譯:a book of mine(我的一本書)
    3、have與of的區(qū)別:
    have一般表示“主動擁有”,往往用于有生命的人或動物;無生命的物體一般不能“主動擁有”,表示所屬關系時要用of.例如:
    I have a new bike.She has two big eyes.
    a door ofthe house
    十一、課本中的知識點
    1、Unit 1 ——Unit 2
    1)問候語:
    Good morning/ afternoon/ evening.
    How are you?---Just OK, thank you. How are you?---Not bad, thanks.
    Hi! Hello!
    How do you do?
    2)道別用語:
    Nice/ Glad to meet/ see you.(meet用于初次見面,see用于熟人間)
    Nice to meet/ see you, too.
    Goodbye. Byebye. Bye. See you (later/ tomorrow/ next time)! So long! Good night!
    3)介紹人或者物的句型:This is...
    4)Excuse me.與I'm sorry.的區(qū)別:
    Excuse me.是要引起對方的注意,而I'm sorry.則是向?qū)Ψ降狼?
    5)詞組be from = come from
    in English
    5)當問句中問到this/ that時,回答要用it;問到these/ those時,要用they來回答. 例如: What's this in English?----It's an eraser.
    What are those?----They are books.
    6)對Thanks.的回答:That's OK./ You're welcome./ My pleasur.
    7)look the same = have the same looks
    give sth. to sb. = give sb. sth.
    be like = look like
    in the tree/ on the tree (樹上結的、長出來的用on,否則用in)
    in red(穿著紅色的衣服)
    in the desk(在空間范圍之內(nèi))
    in English(用英語)
    help sb. do sth.
    8)both與all的區(qū)別:
    both表示“兩者都.”;all表示“三者及以上都.”.
    2、Unit 3——Unit 4
    1)speak的用法
    speak與say不同:speak表示“說”的動作,不表示“說”的內(nèi)容;say則表示“說”的內(nèi)容.
    speak后面除了能接“語言”外,不能直接接東西,后面加了to則表示“對.說”.
    help sb. with sth.(幫助某人做/補習.)
    want to do sth.(想要做某事)
    would like to do sth.
    not...at all(一點都不);Not at all.(沒關系/別介意)
    like...a lot = like...very much
    2)some和any的區(qū)別:
    口訣:some用于肯定句,否定、疑問變any.例如:
    I have some money.
    I don't have any money.
    Do you have any money?
    3)have a seat = take a seat(請隨便坐)
    4)祈使句(表示命令或請求的句子)
    祈使句一般都省略了主語You,所以其否定句直接用Don't開頭.例如:
    Don't go there!
    5)問職業(yè):
    What does sb. do?
    What is sb.?
    What's sb.'s job?
    6)work與job的區(qū)別:
    work是未必有報酬的“工作”,例如homework, housework;而job則一定是有報酬的“工作”.
    7)on指在物體的表面,不論這個面是否水平的,例如:
    on the desk/ wall/ farm/ playground
    8)in hospital(住院);in the hospital(在醫(yī)院里)
    look after(照料/照顧/照看)
    help oneself(請自便/隨便吃)
    9)表示“建議”的句型:“做某事如何?”
    What about (doing) sth.? (英式英語)
    How about (doing) sth.? (美式英語)
    Why don't you do sth.? = Why not do sth.?
    10)“吃”一日三餐要用have:have breakfast/ lunch/ supper
    have...for breakfast/ lunch/ supper
    take one's order
    be kind to sb.
    11)try on這個詞組可合可分:名詞可以放在這個詞組的中間或后面,但代詞只能放在詞組的中間.
    12)在口語中往往用take表示“買”.
    13)how many與how much的區(qū)別:
    how many + 可數(shù)名詞;how much + 不可數(shù)名詞
    14)What do you think of...?是詢問對方對某事物的看法;
    How do you like...?是問對方對某事物喜歡的程度.
    think about(考慮)
    Thank you all the same. (即使對方?jīng)]能幫上忙,也要禮貌道謝)
    Thanks. = Thank you.(thank作為動詞,不能單獨使用.)
    15)one與it的區(qū)別:
    當上下文說的是同一種類事物時,任意一個可以用one來代替;如果上下文所說的是同一個事物時則用it.例如:
    Ann :I have a yellow bag.
    Jane :I have a green one.
    Tom : Hey, Mike. Where is your bike?
    Mike : Look, it's over there.
    16)倒裝句
    Here you are.
    Here it is.
    17)be free (有空/免費)
    forget to do sth.(忘了去做某事)
    forget doing sth.(忘了做過某事)
    What's up? = What's wrong with...? = What's the matter with...?
    18)go + v.-ing結構的含義:為了實現(xiàn)某目的才去的.例如:
    go fishing/ boating/ swimming/ shopping等
    19)have to do sth.(非主觀因素,強調(diào)客觀因素,“不得不去做某事”)
    must 則表示主觀愿望
    20)fly a kite = fly kites
    be free = have time
    21)時間的表述
    當分針所指的時間大于0分、小于等于30分鐘時,用“分鐘”past“小時”.例如:
    8:23——twenty-three past eight
    當分針所指的時間大于30分鐘、小于60分鐘時,用“剩余的時間”to“下一個整點”.例如:
    8:49——eleven to nine
    當然,還可以直接按照小時、分鐘去讀出時間,例如:
    8:23——eight twenty-three; 8:49——eight forty-nine
    整點則在數(shù)詞后加“-o'clock”,例如:8:00——eight o'clock
    在鐘點前介詞要用at.
    22)句型“該干某事了.”:It's time to do sth. = It's time for sth.
    例如:該吃午飯了.
    It's time to have lunch. = It's time for lunch.
