㈢ 七年級英語語法

一般就是名次的單復數,名詞的格,冠詞等,1. 形容詞的用法;
2. 副詞的用法;3. 形容詞和副詞原級、比較級、最高級的用法;4. 形容詞和副詞在句中的區別和位置。我覺得最重要的是動詞了

下面是我暑假用的一些

初中英語語法總結

( 動詞的時態)

11.1 一般現在時的用法

1) 經常性或習慣性的動作,常與表示頻度的時間狀語連用。時間狀語: every…, sometimes, at…, on Sunday。例如:

I leave home for school at 7 every morning. 每天早上我七點離開家。

2) 客觀真理,客觀存在,科學事實。例如:

The earth moves around the sun. 地球繞太陽轉動。

Shanghai lies in the east of China. 上海位於中國東部。

3) 表示格言或警句。例如:

Pride goes before a fall. 驕者必敗。

注意:此用法如果出現在賓語從句中,即使主句是過去時,從句謂語也要用一般現在時。

例:Columbus proved that the earth is round. 哥倫布證實了地球是圓的。

4) 現在時刻的狀態、能力、性格、個性。例如:

I don't want so much. 我不要那麼多。

Ann writes good English but does not speak well.
安英語寫得不錯,講的可不行。

比較:Now I put the sugar in the cup. 把糖放入杯子。

I am doing my homework now. 我正在做功課。

第一句用一般現在時,用於操作演示或指導說明的示範性動作,表示言行的瞬間動作。第二句中的now是進行時的標志,表示正在進行的動作的客觀狀況,所以後句用一般現在時。

11.2 一般過去時的用法

1)在確定的過去時間里所發生的動作或存在的狀態。例如:時間狀語有:yesterday, last week, an hour ago, the other day, in 1982等。例如:

Where did you go just now? 剛才你上哪兒去了?

2)表示在過去一段時間內,經常性或習慣性的動作。例如:

When I was a child, I often played football in the street.
我是個孩子的時候,常在馬路上踢足球。

Whenever the Browns went ring their visit, they were given a
warm welcome.

那時,布朗一家無論什麼時候去,都受到熱烈歡迎。

3)句型:It is time for sb. to do sth "到……時間了" "該……了"。例如:It is
time for you to go to bed. 你該睡覺了。

It is time that sb. did sth. "時間已遲了" "早該……了" ,例如It is time you
went to bed. 你早該睡覺了。

would (had) rather sb. did sth. 表示'寧願某人做某事'。例如:I'd rather you
came tomorrow.還是明天來吧。

4) wish, wonder, think, hope 等用過去時,作試探性的詢問、請求、建議等,而一般過去時表示的動作或狀態都已成為過去,現已不復存在

。例如:I thought you might have some. 我以為你想要一些。

比較:Christine was an invalid all her life.(含義:她已不在人間。)

Christine has been an invalid all her life.(含義:她現在還活著)

Mrs. Darby lived in Kentucky for seven years.
(含義:達比太太已不再住在肯塔基州。)

Mrs. Darby has lived in Kentucky for seven years.
(含義:現在還住在肯塔基州,有可能指剛離去)

注意: 用過去時表示現在,表示委婉語氣。

1)動詞want, hope, wonder, think, intend 等。例如:

Did you want anything else? 您還要些什麼嗎?

I wondered if you could help me. 能不能幫我一下。

2)情態動詞 could, would。例如:

Could you lend me your bike? 你的自行車,能借用一些嗎?

11.3 used to / be used to

used to + do:"過去常常"表示過去習慣性的動作或狀態,但如今已不存在。例如:

Mother used not to be so forgetful. 老媽過去沒那麼健忘。

Scarf used to take a walk. 斯卡夫過去常常散步。

be used to + doing:對……已感到習慣,或"習慣於",to是介詞,後需加名詞或動名詞。例如:

He is used to a vegetarian diet.

Scarf is used to taking a walk. 斯卡夫現在已習慣於散步了。

典型例題

---- Your phone number again? I ___ quite catch it.

---- It's 69568442.

A. didn't B. couldn't C. don't D. can't

答案A. 本句雖沒有明確的時間狀語,但從語意上看出,在聽的時候沒有聽懂這個動作發生在過去,因此應用過去時。

11.4 一般將來時

1) shall用於第一人稱,常被will 所代替。will 在陳述句中用於各人稱,在徵求意見時常用於第二人稱。例如:

Which paragraph shall I read first? 我先讀哪一段呢?

Will you be at home at seven this evening? 今晚七點回家好嗎?

2) be going to +不定式,表示將來。

a. 主語的意圖,即將做某事。例如:What are you going to do tomorrow? 明天打算作什麼呢?

b. 計劃,安排要發生的事。例如:The play is going to be proced next
month。這出戲下月開播。

c. 有跡象要發生的事。例如:Look at the dark clouds, there is going to be a
storm. 看那烏雲,快要下雨了。

3) be +不定式表將來,按計劃或正式安排將發生的事。例如:

We are to discuss the report next Saturday.我們下星期六討論這份報告。

4) be about to +不定式,意為馬上做某事。例如:

He is about to leave for Beijing. 他馬上要去北京。

注意:be about to do 不能與tomorrow, next week 等表示明確將來時的時間狀語連用。

11.5 be going to / will 用於條件句時,be going to表將來,will表意願。例如:

If you are going to make a journey, you'd better get ready for it as soon as possible.

Now if you will take off your clothes, we will fit the new clothes on you in front of the mirror.

11.6 be to和be going to

be to 表示客觀安排或受人指示而做某事,be going to 表示主觀的打算或計劃。例如:

I am to play football tomorrow afternoon. 明天下午我去踢球。(客觀安排)

I'm going to play football tomorrow afternoon.
明天下午我想去踢球。(主觀安排)

11.7 一般現在時表將來

1)下列動詞come, go, arrive, leave, start, begin, return的一般現在時可以表示將來,主要用來表示在時間上已確定或安排好的事情。例如:

The train leaves at six tomorrow morning. 火車明天上午六點開。

When does the bus star? It stars in ten minutes. 汽車什麼時候開?十分鍾後。

2)以here, there等開始的倒裝句,表示動作正在進行。例如:

Here comes the bus. = The bus is coming. 車來了。

There goes the bell. = The bell is ringing. 鈴響了。

3)在時間或條件句中。例如:

When Bill comes (不是will come), ask him to wait for me. 比爾來後,讓他等我。

I'll write to you as soon as I arrive there. 我到了那裡,就寫信給你。

4)在動詞hope, take care that, make sure that等的賓語從句中。例如:

I hope they have a nice time next week. 我希望他們下星期玩得開心。

Make sure that the windows are closed before you leave the room. 離開房間前,務必把窗戶關了。

11.8 用現在進行時表示將來

下列動詞come, go, arrive, leave, start, begin, return等現在進行時可以表示將來。例如:

I'm leaving tomorrow. 明天我要走了。

Are you staying here till next week? 你會在這兒呆到下周嗎?

11.9 現在完成時

現在完成時用來表示之前已發生或完成的動作或狀態,其結果的影響現在還存在;也可表示持續到現在的動作或狀態。其構成:have(has) +過去分詞。

11.10 比較一般過去時與現在完成時

1)一般過去時表示過去某時發生的動作或單純敘述過去的事情,強調動作;現在完成時為過去發生的,強調過去的事情對現在的影響,強調的是影響。

2)一般過去時常與具體的時間狀語連用,而現在完成時通常與模糊的時間狀語連用,或無時間狀語。

一般過去時的時間狀語:yesterday, last week,…ago, in1980, in October, just
now等,皆為具體的時間狀語。

現在完成時的時間狀語:for, since, so far, ever, never, just, yet, till/until, up to now, in past years, always等,皆不確定的時間狀語。

共同的時間狀語:this morning, tonight, this April, now, already, recently, lately 等。

3)現在完成時可表示持續到現在的動作或狀態,動詞一般是延續性的,如live, teach, learn, work, study, know.。

一般過去時常用的非持續性動詞有come, go, leave, start, die, finish, become, get married等。例如:

I saw this film yesterday. (強調看的動作發生過了)

I have seen this film. (強調對現在的影響,電影的內容已經知道了)

Why did you get up so early? (強調起床的動作已發生過了)

Who hasn't handed in his paper? (強調有卷子未交,疑為不公平競爭)

He has been in the League for three years. (在團內的狀態可延續)

He has been a League member for three years. (是團員的狀態可持續)

句子中如有過去時的時間副詞(如yesterday, last, week, in 1960)時,不能使用現在完成時,要用過去時。

(錯)Tom has written a letter to his parents last night.

(對)Tom wrote a letter to his parents last night.

11.11 用於現在完成時的句型

1)It is the first / second time.... that…結構中的從句部分,用現在完成時。例如:

It is the first time that I have visited the city. 這是我第一次訪問這城市。

This is the first time (that) I've heard him sing. 這是我第一次聽他唱歌。

注意:It was the third time that the boy had been late.

2)This is +形容詞最高級+that…結構,that 從句要用現在完成時。例如:

This is the best film that I've (ever) seen. 這是我看過的最好的電影。

典型例題

(1) ---Do you know our town at all? ---No, this is the first time I ___ here.

A. was B. have been C. came D. am coming

答案B. This is the first time 後面所加從句應為現在完成時,故選B。

(2) ---Have you ____ been to our town before? ---No, it's the first time I ___ here.

A. even, come B. even, have come C. ever, come D. ever, have come

答案D. ever意為曾經或無論何時,反意詞為never,此兩詞常用於完成時。

注意:非延續性動詞的否定形式可以與表示延續時間的狀語連用。即動作不發生的狀態是可以持續的。

(錯)I have received his letter for a month.

(對)I haven't received his letter for almost a month.

11.12 比較since和for

Since 用來說明動作起始時間,for用來說明動作延續時間長度。例如:
I have lived here for more than twenty years.我住在這兒二十多年了。
I have lived here since I was born. 我從出生起就住在這兒了。
注意:並非有for 作為時間狀語的句子都用現在完成時。
I worked here for more than twenty years. (我現在已不在這里工作。)
I have worked here for many years.(現在我仍在這里工作。)
注意:用句型轉換的方法,很容易排除非延續動詞在有for/since結構的完成時中的誤用。
1)(對) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now.
2)(錯) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now.
顯然,第二句不對,它應改為 Harry got married six years ago. 或 Harry has been married for six years.
11.13 since的四種用法

1) since +過去一個時間點(如具體的年、月、日期、鍾點、1980, last month, half past
six)。例如:

I have been here since 1989. 1989起,我一直在這兒。

2) since +一段時間+ ago。例如:

I have been here since five months ago. 我在這兒,已經有五個月了。

3) since +從句。例如:

Great changes have taken place since you left. 你走後,變化可大了。

Great changes have taken place since we were here. 我們走後,變化可大了。

4) It is +一段時間+ since從句。例如:

It is two years since I became a postgraate student. 我考上研究生有兩年了。

11.14 延續動詞與瞬間動詞

1) 用於完成時的區別

延續動詞表示經驗、經歷; 瞬間動詞表示行為的結果,不能與表示段的時間狀語連用。例如:

He has completed the work. 他已完成了那項工作。 (表結果)

I've known him since then. 我從那時起就認識他了。(表經歷)

2) 用於till / until從句的差異

延續動詞用於肯定句,表示"做……直到……" 瞬間動詞用於否定句,表示"到……,才……"。例如:

He didn't come back until ten o'clock. 他到10 點才回來。

He slept until ten o'clock. 他一直睡到10點。

典型例題

1. You don't need to describe her. I ___ her several times.

A. had met B. have met C. met D. meet

答案B. 首先本題後句強調對現在的影響,我知道她的模樣,你不用描述。再次,several
times告知為反復發生的動作,因此用現在完成時。

2. ---I'm sorry to keep you waiting.

---Oh, not at all. I ___here only a few minutes.

A. have been B. had been C. was D. will be

答案A. 等待的動作由過去開始,持續到現在,應用現在完成時。

11.15 過去完成時

1) 概念:表示過去的過去

----|----------|--------|----> 其構成是had +過去分詞構成。 那時以前 那時 現在

2) 用法

a. 在told, said, knew, heard, thought等動詞後的賓語從句。例如:

She said (that)she had never been to Paris. 她告訴我她曾去過巴黎。

b. 狀語從句

在過去不同時間發生的兩個動作中,發生在先,用過去完成時;發生在後,用一般過去時。例如:

When the police arrived, the thieves had run away. 警察到達時,小偷們早就跑了。

c. 表示意向的動詞,如hope, wish, expect, think, intend, mean, suppose等,用過去完成時表示"原本…,未能…"。例如:

We had hoped that you would come, but you didn't. 那時我們希望你能來,但是你沒有來。

3) 過去完成時的時間狀語before, by, until , when, after, once, as soon
as。例如:

He said that he had learned some English before. 他說過他以前學過一些英語。

By the time he was twelve, Edison had began to make a living by himself. 到了十二歲那年,愛迪生開始自己謀生。

Tom was disappointed that most of the guests had left when he arrived at the party.

湯姆失望了,因為他到達晚會時,大部分客人已經走了。

典型例題

The students ___ busily when Miss Brown went to get a book she ___ in the office.

A. had written, left B,were writing, has left C. had written, had left D. were writing, had left

答案D.
"把書忘在辦公室"發生在"去取書"這一過去的動作之前,因此"忘了書"這一動作發生在過去的過去,用過去完成時。句中when表示的是時間的一點,表示在"同學們正忙於……"這一背景下,when所引導的動作發生。因此前一句應用過去進行時。

注意: had hardly… when 還沒等…… 就……。例如:

I had hardly opened the door when I he hit me. 我剛打開門,他就打了我。

had no sooner…than 剛…… 就……。例如:

He had no sooner bought the car than he sold it. 他剛買了這輛車,轉眼又賣了。

11.16 用一般過去時代替過去完成時

1) 兩個動作如按順序發生,又不強調先後,或用then,and,but 等連詞時,多用一般過去時。例如:

When she saw the mouse,she screamed. 她看到老鼠,就叫了起來。

My aunt gave me a hat and I lost it. 姑媽給了我一頂帽子,我把它丟了。

2 ) 兩個動作相繼發生,可用一般過去時;如第一個動作需要若干時間完成,用過去完成時。例如:

When I heard the news, I was very excited.

3) 敘述歷史事實,可不用過去完成時,而只用一般過去時。例如:

Our teacher told us that Columbus discovered America in 1492.

11.17 將來完成時

1) 構成will have done

2) 概念

a. 狀態完成:表示某事繼續到將來某一時為止一直有的狀態。例如:

They will have been married for 20 years by then. 到那時他們結婚將有二十年了。

b. 動作完成:表示將來某一時或另一個將來的動作之前,已經完成的動作或獲得的經驗。例如:

You will have reached Shanghai by this time tomorrow. 明天此時,你已經到達上海了。

11.18 現在進行時

現在進行時的基本用法:

a. 表示現在(指說話人說話時)正在發生的事情。例如: We are waiting for you. 我們正在等你。

b. 習慣進行:表示長期的或重復性的動作,說話時動作未必正在進行。例如:

Mr. Green is writing another novel. 他在寫另一部小說。(說話時並未在寫,只處於寫作的狀態。)

c. 表示漸變,這樣的動詞有:get, grow, become, turn, run, go, begin等。例如:

The leaves are turning red. 葉子在變紅。

It's getting warmer and warmer. 天越來越熱了。

d. 與always, constantly, forever 等詞連用,表示反復發生的動作或持續存在的狀態,往往帶有說話人的主觀色彩。例如:

You are always changing your mind. 你老是改變主意。

典型例題

My dictionary ___, I have looked for it everywhere but still___ it.

A. has lost, don't find B. is missing, don't find C. has lost, haven't found D. is missing, haven't found.

答案D. 前句是一個仍在持續的狀態,應用進行時,由於沒有找到,其影響仍然存在,應用完成時,瞬間動詞用於否定式時可用於完成時。

11.19 不用進行時的動詞

1)表示事實狀態的動詞,如have, belong, possess, cost, owe, exist, include,
contain, matter, weigh, measure, continue等。例如:I have two brothers. 我有兩兄弟。

This house belongs to my sister. 這房子是我姐的。

2)表示心理狀態的動詞,如know, realize, think see, believe, suppose, imagine, agree, recognize, remember, want, need, forget, prefer, mean, understand, love, hate等。例如:I need your help. 我需要你的幫助。

He loves her very much. 他愛她很深。

3)瞬間動詞,如accept, receive, complete, finish, give, allow, decide, refuse等。例如:

I accept your advice. 我接受你的勸告。

4)系動詞,如seem, remain, lie, see, hear, smell, feel, taste, get, become, turn等。例如:

You seem a little tired. 你看上去有點累。

11.20 過去進行時

1)概念:表示過去某時正在進行的狀態或動作。

2)過去進行時的主要用法是描述一件事發生的背景;一個長動作延續的時候,另一個短動作發生。

3) 常用的時間狀語有this morning, the whole morning, all day yesterday, from nine to ten last evening, when, while等。例如:

My brother fell while he was riding his bicycle and hurt himself. 我兄弟騎車時摔了下來,受了傷。

It was raining when they left the station. 他們離開車站時,正下著雨。

When I got to the top of the mountain, the sun was shining. 我到達山頂時,陽光燦爛。

典型例題

1) Mary ___ a dress when she cut her finger.

A. made B. is making C. was making D. makes

答案C.
割傷手指是已發生的事情,應用過去時。同時,when表時間的同時性,"瑪麗在做衣服時"提供事情發生的背景,因此用過去進行時。

2) As she ___ the newspaper, Granny ___ asleep.

A. read;was falling B. was reading; fell C. was reading; was falling D. read;fell

答案B.句中的as = when, while,意為"當……之時"。描述一件事發生的背景時,用過去進行;一個長動作發生的時候,另一個短動作發生。句意為 "在她看報紙時,奶奶睡著了。"句中的 fell(fall的過去時),是系動詞,後跟形容詞,如:fall sick。

㈣ 七年級競賽英語語法和數學公式、定理等必背東西。拜託啦,各位大哥大姐,叔叔阿姨,爺爺奶奶。

一、七年級英語語法——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:

㈨ 初一二英語全部語法公式

代詞

代詞是代替名詞的一種詞類。大多數代詞具有名詞和形容詞的功能。英語中的代詞,按其意義、特徵及在句中的作用分為:人稱代詞、物主代詞、指示代詞、自身代詞、相互代詞、疑問代詞、關系代詞和不定代詞八種。

一、人稱代詞是表示"我"、"你"、"他"、"她"、"它"、
"我們"、"你們"、"他們"的詞。人稱代詞有人稱、數和格的變化,見下表:

數 單數 復數
格 主格 賓格 主格 賓格
第一人稱 I me we us
第二人稱 you you you you
he him they them
第三人稱 she her they them
it it they them

如:He is my friend. 他是我的朋友。
It』s me. 是我。

二、 物主代詞表示所有關系的代詞,也可叫做代詞所有格。物主代詞分形容性物主代詞和名詞性物主代詞二種,其人物和數的變化見下表。

數 單數 復數
人稱 第一 第二 第三 第一 第二 第三
人稱 人稱 人稱 人稱 人稱 人稱
形容詞性 my your his/her its our your/their
物主代詞

名詞性 mine yours his/hers its ours yours/theirs
物主代詞

如: I like his car.
我喜歡他的小汽車。
Our school is here,and theirs is there.
我們的學校在這兒,他們的在那兒。

三、 指示代詞表示"那個"、"這個"、"這些"、"那些"等指示概念的代詞。指示代詞有this,that,these,those等。
如: That is a good idea. 那是個好主意。

四、 表示"我自己"、"你自己"、"他自己"、"我們自己"、"你們自己"和"他們自己"等的代詞,叫做自身代詞,也稱為"反身代詞"。
如: She was talking to herself. 她自言自語。

五、 表示相互關系的代詞叫相互代詞,有each other&n bsp;和one another兩組,但在運用中,這兩組詞沒什麼區別。
如: They love each other. 他們彼此相愛。

六、 不是指明代替任何特定名詞的代詞叫做不定代詞。常見的不定代詞有a11,both,each,every等,以及含有some-,any-,no-等的合成代詞,如anybody, something,no one。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, 但none和由some,any,no等構成的復合不定代詞只能作主語、賓語或表語;every和no只能作定語。如:

--- Do you have a car? --你有一輛小汽車嗎?
--- Yes,I have one. --是的,我有一輛。
--- I don』t know any of them. 他們,我一個也不認識。

七、 疑問代詞有who,whom,whose,what和which等。在句子中用來構成特殊疑問句。疑問代詞都可用作連接代詞,引導名詞性從句(主語從句、賓語從句和表語從句)
如:Tell me who he is. 告訴我他是誰。

八、 關系代詞有who,whom,whose,that,which,as等,可用作引導從句的關聯詞。它們在定語從句中可作主語、表語、賓語、定語等;另一方面它們又代表主句中為定語從句所修飾的那個名詞或代詞(通稱為先行詞)。
如: He is the man whom you have been looking for. 他就是你要找的那個人。

3.1 人稱代詞的用法

1)人稱代詞的主格在句子中作主語或主語補語,例如:
John waited a while but eventually he went home.
約翰等了一會兒,最後他回家了。
John hoped the passenger would be Mary and indeed it was she.
約翰希望那位乘客是瑪麗,還真是她。

說明:在復合句中,如果主句和從句主語相同,代詞主語要用在從句中,名詞主語用在主句中,例如:
When he arrived, John went straight to the bank.
約翰一到就直接去銀行了。

2)人稱代詞的賓格在句子中作賓語或介詞賓語,但在口語中也能作主語補語,第一人稱在省略句中,還可以作主語,例如:
I saw her with them, at least, I thought it was her.
我看到她和他們在一起,至少我認為是她。(her做賓 語,them做介詞賓語,her做主語補語)
a. -- Who broke the& nbsp;vase? --誰打碎了花瓶?
b. -- Me. --我。(me做主語補語= It』s me.)

說明:在上面兩例句中,her和me分別作主語補語。現代英語中多用賓格,在正式文體中這里應為she和I。

3.2 人稱代詞之主、賓格的替換

1) 賓格代替主格
a.在簡短對話中,當人稱代詞單獨使用或在not 後,多用賓語。
---- I like English. --我喜歡英語。
---- Me too. --我也喜歡。
---- Have more wine? --再來點酒喝嗎?
---- Not me. --我可不要了。

b.在表示比較的非正式的文體中,常用賓格代替主格。 但如果比較狀語的謂語保留,則主語只能用主格。

2) 主格代替賓格
a. 在介詞but,except 後,有時可用主格代替賓格。

b. 在電話用語中常用主格。

---- This is she. --我就是瑪麗。

注意:在動詞be 或to be 後的人稱代詞視其前面的名詞或代詞而定。
I thought it was she. 我以為是她。 (主格----主格)
I thought it to be her. (賓格----賓格)
I was taken to be she. 我被當成了她。 (主格----主格)
They took me to be her. 他們把我當成了她。 (賓格----賓格)

Nobody came, did he? 誰也沒來,是嗎?

2)動物名詞的指代一般用it或they代替,有時也用he, she,帶有親切的感情色彩。

㈩ 求七年級的語法公式!如:。介詞+Ving,Don't+V原形

七年級英語語法雖然是從簡單的一些日常用語出發的,但語法中常會有一些知識點看起來很細小,容易被忽視,但這些知識點掌握不熟練,往往會造成一些語法應用上的錯誤.因此在學習七年級英語語法時,要認真、細心,不要覺得一些地方不重要而得過且過.
下面從幾個方面,總結出了七年級英語語法,如果要復習英語句法的同學,可以參考一下,
一、七年級英語語法——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

第一人稱 單數 I me my mine myself
復數 we us our ours ourselves

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:

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
