C. 初一英語上冊，每個單元知識語法總結點
初一英語語法總結
一、 詞法 1、名詞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：
一）在後面加s。如：fathers, books, Americans, Germans, apples, bananas
二）x, sh, ch, s, tch後加es。如：boxes, glasses, dresses, watches, wishes, faxes
三）1）以輔音字母加y結尾的變y為i再加es 如：baby-babies, family-families, ty-ties, comedy-comedies, documentary-documentaries, story-stories
2）以母音字母加y結尾的直接加s。如：day-days, boy-boys, toy-toys, key-keys, ways
四）以o結尾加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）單復數相同（不變的）有：fish, sheep, deer鹿子, Chinese, Japanese
七）一般只有復數，沒有單數的有：people,pants, shorts, shoes, glasses, gloves, clothes, socks
八）單詞形式不變，既可以是單數也可以是復數的有：police警察局，警察, class班，同學, family家，家庭成員
九）合成的復數一般只加主要名詞，多數為後一個單詞。如：action movie-action movies, pen pal-pen pals; 但如果是由man或woman所組成的合成詞的復數則同時為復數。如：man doctor-men doctors, woman teacher-women teachers
十）有的單復數意思不同。如：fish魚 fishes魚的種類, paper紙 papers報紙，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時間 times時代, 次數, chicken 雞肉 chickens 小雞
十一） 單個字母的復數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-Englishmen
B）名詞的格
當我們要表示某人的什麼東西或人時，我們就要使用所有格形式。構成如下：
一）單數在後面加』s。如：brother』s, Mike』s, teacher』s
二）復數以s結尾的直接在s後加』，如果不是以s結尾的與單數一樣處理。如：Teachers』 Day教師節, classmates』; Children』s Day六一節, Women』s Day三八節
三）由and並列的名詞所有時，如果是共同所有同一人或物時，只加最後一個』s，但分別擁有時卻分別按單數形式處理。如：Mike and Ben』s room邁克和本的房間（共住一間），Mike』s and Ben』s rooms邁克和本的房間（各自的房間）
2、代詞 項目 人稱代詞 物主代詞 指示代詞 反身代詞

復數 you you your yours yourselves
第三人稱 單數 she her her hers herself
he him his his himself it it its its this that itself
復數 they them their theirs these those themselves
3、動詞 A） 第三人稱單數
當動詞是第三人稱單數時，動詞應該像名詞的單數變動詞那樣加s，如下：
一）一般在詞後加s。如：comes, spells, waits, talks, sees, dances, trains
二）在x, sh, ch, s, tch後加es。如：watches, washes, wishes, finishes

四）以o結尾加es。如：does, goes 五）特殊的有：are-is, have-has
B） 現在分詞
當我們說某人正在做什麼事時，動詞要使用分詞形式，不能用原形，構成如下：
一）一般在後加ing。如：spell-spelling, sing-singing, see-seeing, train-training, play-playing, hurry-hurrying, watch-watching, go-going, do-doing
二）以不發音e的結尾的去掉e再加ing。如：dance-dancing, wake-waking, take-taking, practice-practicing, write-writing, have-having
三）以重讀閉音節結尾且一個母音字母＋一個輔音字母（注意除開字母組合如show –showing, draw-drawing）要雙寫最後的輔音字母再加ing。如：put-putting, run-running, get-getting, let-letting, begin-beginning
四）以ie結尾的變ie為y再加ing。如：tie-tying系 die-dying死 lie-lying 位於
4、形容詞的級
我們在對兩個或以上的人或物進行對比時，則要使用比較或最高級形式。構成如下：
一） 一般在詞後加er或est(如果是以e結尾則直接加r或st)。如：greater-greatest, shorter –shortest, taller –tallest, longer –longest, nicer- nicest, larger -largest
二）以重讀閉音節結尾且1個母音字母＋1個輔音字母(字母組合除外，如few-fewer fewest)結尾的雙寫結尾的輔音再加er /est。如：big-bigger biggest, red-redder reddest, hot-hotter hottest
三） 以輔音字母＋y結尾的變y為i加er/est。如：happy-happier happiest, sorry-sorrier sorriest, friendly-friendlier friendliest(more friendly most friendly), busy-busier busiest, easy-easier easiest
四）特殊情況：(兩好多壞，一少老遠)
good/well - better best many/much - more most bad/ill – worse worst
little- less least old- older/elder oldest/eldest far- farther/further farthest/furthest
5、數詞 (基變序，有規則；一、二、三，自己背；五、八、九、十二；其它後接th；y結尾，變為i, eth跟上去。) first, second, third; fifth, eighth, ninth, twelfth; seventh, tenth, thirteenth, hundredth; twenty-twentieth, forty-fortieth, ninety-ninetieth

【名師講解】
1.That's right./ That『s all right./ All right.
That』s right意為「對的」，表示贊同對方的意見、看法或行為，肯定對方的答案或判斷。例如：
"I think we must help the old man.""我想我們應該幫助這位老人。"
"That's right."或 "You're right.""說得對"。
That』s all right.意為「不用謝」、「沒關系」，用來回答對方的致謝或道歉。例如：
"Many thanks." "That's all right." "Sorry. It's broken." "That's all right."
All right.意為「行了」、「可以」，表示同意對方的建議或要求。有時還可以表示「身體很好」
"Please tell me about it." "請把此事告訴我。""All right.""好吧。"Is your mother all right?你媽身體好嗎
2. make/do
這兩個詞都可以解釋為「做」，但含義卻不同，不能混用。make指做東西或制東西，do指做一件具體的事。
Can you make a paper boat for me? 你能為我做個紙船嗎？He』s doing his homework now.他正在做他的作業。
3. say/speak/talk/tell
say：是最口語化的最普通的一個詞，意為「說出」、「說道」，著重所說的話。如：
「I want to go there by bus」 , he said . 他說，「我要坐汽車到那裡去。」Please say it in English .請用英語說。
speak : 「說話」，著重開口發聲，不著重所說的內容，一般用作不及物動詞 (即後面不能直接接賓語 ) 。如：
Can you speak about him? 你能不能說說他的情況？I don』t like to speak like this. 我不喜歡這樣說話。
speak 作及物動詞解時，只能和某種語言等連用，表達在對話中恰當使用詞彙的能力。
如：She speaks English well.她英語說得好。
talk : 與 speak 意義相近，也著重說話的動作，而不著重所說的話，因此，一般也只用作不及物動詞， 不過，talk 暗示話是對某人說的，有較強的對話意味，著重指連續地和別人談話。如：
I would like to talk to him about it . 我想跟他談那件事。
Old women like to talk with children.老年婦女喜歡和孩子們交談。tell : 「告訴」，除較少情況外，一般後面總接雙賓語。如：He』s telling me a story.他在給我講故事。tell a lie 撒謊tell sb. to do sth. /tell sb. not to do sth.
Miss Zhao often tells us to study hard.
4. do cooking/ do the cooking
do cooking 作「做飯」解，屬泛指。do the cooking 特指某一頓飯或某一家人的飯。cooking為動名詞，不能用作復數，但前面可用 some, much修飾。從do some cooking可引出許多類似的短語：
do some washing 洗些衣服do some shopping 買些東西do some reading 讀書do some writing 寫些東西
do some fishing 釣魚從以上短語可引申出另一類短語，不能用some, much或定冠詞。
go shopping 去買東西go fishing 去釣魚go boating 去劃船go swimming 去游泳
5. like doing sth./ like to do sth.
like doing sth. 與like to do sth. 意思相同，但用法有區別。前者強調一般性的愛好或者表示動作的習慣性和經常性；後來表示一次性和偶然性的動作。例如：
He likes playing football, but he doesn『t like to play football with Li Ming.
他喜歡踢足球，但是他不喜歡和李明踢。
6. other/ others/ the other/ another
other表其餘的，別的， Have you any other questions?你還有其他問題嗎?
others 別的人，別的東西 In the room some people are American, the others are French.
在屋子裡一些人是美國人,其他的是法國人。
the other表另一個（二者之中）one…，the other…
One of my two brothers studies English, the other studies Chinese.
我兩個哥哥中的一個學習英文,另一個學中文。another表三者以上的另一個，另一些
There is room for another few books on the shelf.書架上還可以放點書。
7. in the tree/ on the tree
in the tree 與 on the tree.譯成中文均為"在樹上"但英語中有區別。in the tree表示某人、某事（不屬於樹本身生長出的別的東西）落在樹上，表示樹的枝、葉、花、果等長在樹上時，要使用on the tree.如：
There are some apples on the tree. 那棵樹上有些蘋果。 There is a bird in the tree. 那棵樹上有隻鳥。
8. some/ any
(1)some和 any既可修飾可數名詞，也可修飾不可數名詞。但有以下兩點需要注意。
some常用於肯定句中，any常用於否定句和疑問句中。如：There is some water in the glass.
Is there any water in the glass?There isn't any water in the glass.
(2)在說話者希望得到肯定答復的一般疑問句中，或在表示請求，邀請的疑問句中，我們依然用some。如：
Would you like some tea?
9. tall/ high
(1)說人，動物，樹木等有生命的東西，主要用tall，不用high，例如 a tall woman 一個高個子婦女
a tall horse 一個高大的馬
(2)說一個不與地面接觸的人和物的高時，要用high，而不用tall，比如人站在桌子上時，飛機飛上天時，例如：
He is high up in the tree. 他高高地爬在樹上。 The plane is so high in the sky. 飛機在空中這么高。
(3)指建築物、山時要tall或high都可以，不過high的程度比tall高。
(4)high可作副詞，tall不能。 (5)tall的反義詞為short, high的反義詞為low.
10. can/ could
(1) can表示體力和腦力方面的能力，或根據客觀條件能做某種動作的"能力"。例如：
Can you ride a bike？ 你會騎自行車嗎？
What can I do for you？ 要幫忙嗎？ Can you make a cake？你會做蛋糕嗎？
(2) can用在否定句和疑問句中時有時表示說話人的"懷疑""猜測"或不肯定。例如：
Where can he be？他會在什麼地方呢？Can the news be true？這個消息會是真的嗎？
It surely can't be six o'clock already？不可能已經六點鍾了吧？
You can't be hungry so soon，Tom，you've just had lunch.湯姆，你不可能餓得這么快，你剛吃過午飯。
What can he mean？他會是什麼意思？在日常會話中，can可代替may表示"允許"，may比較正式。例如：
You can come in any time.你隨時都可以來。--- Can I use your pen？我能用你的鋼筆嗎？
--- Of course，you can.當然可以。You can have my seat，I'm going now.我要走了，你坐我的座位吧。
(3) could
could 是 can的過去式，表示過去有過的能力和可能性（在否定和疑問句中）。例如：
The doctor said he could help him.（能力）醫生說他能幫助他。
Lily could swim when she was four years old.（能力） 當麗麗四歲的時候她就會游泳。
At that time we thought the story could be true.（可能性）那時我們以為所說的可能是真的。
could可代替can表示現在時間的動作，但語氣較為婉轉。例如：Could I speak to John，please？我能和約翰說話嗎？ Could you？在口語中表示請求對方做事。例如：Could you wait half an hour？請你等半個小時好嗎？
Could you please ring again at six？六點鍾請你再打電話好嗎？
(4) can的形式
只有現在式can和過去式could兩種形式。能表示一般現在和一般過去兩種時態，有時也能表示將來。所有其他時態（包括將來時）須用be able to加動詞不定式來表示。例如： They have not been able to come to Beijing.
他們沒有能到北京來。
11. look for/ find
look for 意為「尋找」，而find意為「找到，發現」，前者強調「找」這一動作，並不注重「找」的結果，而後者則強調「找」的結果。例如：She can』t find her ruler. 她找不到她的尺子啦。
Tom is looking for his watch，but he can』t find it.湯姆正在尋找他的手錶，但沒能找到。
12. be sleeping/ be asleep
be sleeping 表示動作，意思是「正在睡覺」；be asleep 表示狀態，意思是「睡著了」。如：
---What are the children doing in the room? 孩子們在房間里做什麼？
---They are sleeping.他們正在睡覺。The children are asleep now.現在孩子們睡著了。
13. often/ usually/sometimes
often表示"經常"，sometimes表示"有時候"，在表示發生頻率上often要高於usually，usually要高於sometimes。這三個詞表示的是經常性，一般性的動作或情況，常與一般現在時連用，常位於主要謂語動詞的前面，其他謂語動詞（be動詞，情態動詞和助動詞）的後面，有時也可位於句尾。如果要加強語氣，則放在句首。
We usually play basketball after school.我們通常放學後打籃球。
Sometimes I go to bed early.有時，我睡覺很早。
He often reads English in the morning.他經常在早晨讀英語。
14. How much/ How many
how much常用來詢問某一商品的價格，常見句式是How much is / are…?
How much is the skirt? 這條裙子多少錢？How much are the bananas? 這些香蕉多少錢？
how much後加不可數名詞，表示數量，意為「多少「，how many後加可數名詞的復數形式。
How much meat do you want? 你要多少肉呀？How many students are there in your class? 你們班有多少人？
15. be good for/ be good to/ be good at
be good for 表示"對……有好處"，而be bad for表示"對……有害"；be good to表示"對……友好"，而be bad to表示"對……不好"；be good at表示"擅長，在……方面做得好"，而be bad at表示"在……方面做得不好"。
