be動詞用法說明

  be動詞有am,is,are三種形式,be動詞的用法你知道嗎?和學(xué)習(xí)啦小編一起來看看吧。
  be動詞用法說明如下:
  be動詞的用法口訣 :
  我(I)用am,你(you)用are,is連著他(he),她(she),它(it);
  單數(shù)名詞用is,復(fù)數(shù)名詞全用are。我們(we)你們(you)和他們(they)都用are;過去式am\is變was,are變 were;變疑問,往前提,句末問號莫丟棄。變否定,更容易,be后not莫忘記。 疑問否定任你變,句首大寫莫遲疑。
  一、be動詞與人稱代詞的搭配
  1、基本形式:am、are、is

  第一人稱I+am     (注意:“I”無論何時都要大寫,不管位于句首還是句中)
  例:I am a beautiful girl.           I am twenty.
  (2)    are
  第二人稱you+are;   一人稱復(fù)數(shù)we+are;  三人稱復(fù)數(shù)they+are  其他復(fù)數(shù)名詞+are   (注意:第二人稱單復(fù)數(shù)同形,都為you)
  例:You are my good friend.        We are in the same class.
  They are on the road.              The books are on the desk.
  (3     is
  第三人稱he(男) +is ; she(女)+is; it(不是人)+is;其他單數(shù)名詞+is
  例:He\She is a good student.         It is a white cat.
  A dog is on that street.
  2、肯定、否定、疑問(等于號后是簡寫)

  how的用法總結(jié)
  一、基本義為“怎么樣”
  一How do you go to school? -I go by bus. 一你是怎么去上學(xué)的? 一我是乘公共汽車去的。
  一How can I get to the cinema? 一You can go by the No. 15 bus. 一我如何到達(dá)電影院呢?-你可以乘坐15路公交。
  How do you feel?--I feel sick.--你感覺怎樣?--我感覺難受。
  二、作為疑問詞的用法
  How tall are you? -I am164cm tall.-你有多高呢?-我有164厘米高。
  How heavy is he? - He is 50kg.-他有多重啊?他50公斤重。
  How big are your feet? -I wear size 36.你穿多大的鞋子呢?我穿3號好的鞋子 。
  How large is your room? -My room is 30 square meters.-你的房間有多大呢?我的房間有30平方米大。
  How old are you? - I am 20 years old.-那你有多大呢?-我20歲了。
  How long are your legs?-76cm.-你的腿有多長呢?-76厘米長。
  三、與much和many連用
  How much (money) do you want? 你需要多少錢?
  How much water in the bottle? -A little.-瓶子里有多少誰呢?-一些。
  How many (pictures) did you buy? 你買了多少幅(畫)?
  四、與副詞連用

  How often do you go abroad? 你多長時間出一次國?

  How soon can you come? 你多快能趕來?
  注意How is she?(她身體怎么樣?)詢問的是她的健康狀況,而What is she like?(她長得什么樣?)詢問的是她的外貌。
  另外,不要把How are you?(你身體怎么樣?)和How do you do?(您好!)搞混。當(dāng)兩個人被介紹認(rèn)識時,雙方都說How do you do?這只是一句問候語而不是真的提出一個問題。
  當(dāng)別人同一問題時可以省略問:How about you?(你呢?)如:
  Lily: How tall is Mike?--邁克多高呢?
  Me: He is 170cm tall.--他有170厘米高。
  Lily: How about you? --你呢?
  Me: I am 165cm. --我有165厘米高。

  be going to 的用法總結(jié)

  一、be going to 的用法點(diǎn)撥
  be going to 是一種固定結(jié)構(gòu),它后面跟動詞原形,用來表示按計劃或安排要發(fā)生的動作或事件,有時也可以表示推測將要或肯定會發(fā)生的動作,有“準(zhǔn)備;打算”的意思。含有be going to 結(jié)構(gòu)的句子中往往有表示將來的時間狀語。例如:
  We are going to play football this afternoon.今天下午我們打算踢足球。(安排)
  Look at the black clouds. It's going to rain.看那些烏云,快要下雨了。(推測)
  二、be going to 在肯定句中的形式
  be going to 結(jié)構(gòu)中的助動詞be很少用原形,它一般有三種形式,即:am , is , are 。當(dāng)主語是 I 時用am ;當(dāng)主語是第三人稱單數(shù)時用is;當(dāng)主語是第二人稱(you)或復(fù)數(shù)時用are。例如:
  I am going to buy some books on Sunday.周日我打算去買些書。
  She is going to visit her aunt and uncle this weekend.她打算這個周末去看望她的阿姨和叔叔。
  You are going to clean your room this afternoon.今天下午你打算打掃你的房間。
  We are going to visit the Great Wall this weekend.我們打算這個周末去參觀長城。
  Mike and John are going to the cinema tomorrow.邁克和約翰打算明天去看電影。
  三、含be going to 的句子變否定句和一般疑問句的變法
  由于句子中有助動詞be,因此be going to 的否定句和一般疑問句的構(gòu)成很容易,即在be (am, is, are) 的后面加上not 就構(gòu)成了否定句;把be (am, is, are) 放到句首,在句末加問號就構(gòu)成了一般疑問句,其答語為:Yes, 主語+ am/is/are. / No, 主語+ isn't/aren't. / No, I'm not.不過 I am... 在改為一般疑問句時常常改為“Are you ....?”。例如:
  They are going to beijing next week. (肯定句)
  They are not going to beijing next week. (否定句)
  -Are they going to beijing next week?
  -Yes, they are. (No, they aren't.) (一般疑問句的肯定與否定回答)
  We are going to play basketball on Saturday. (肯定句)
  We are not going to play basketball on Saturday.  (否定句)
  -Are you going to play basketball on Saturday? (一般疑問句)
  -     Yes, we are.  (No, we aren't )  (一般疑問句的肯定與否定回答  )
  He is going to do his homework Saturday afternoon. (肯定句)
  He is not going to do his homework Saturday afternoon.. (否定句)
  -Is he going to do his homework Saturday afternoon?  (一般疑問句)
  -     -Yes, he is.  ( No,  he isn't.)  (一般疑問句的肯定與否定回答 )
  四、使用be going to 應(yīng)注意的兩點(diǎn)
  1. There be 句型的be going to 結(jié)構(gòu)為:There is / are going to be... (注意句型中g(shù)oing to 后面的be不能改為have。) 常用來表示將有某事發(fā)生。例如:
  There is going to be a football match next Saturday in our school.下周六我們學(xué)校將有一場足球比賽。
  2. come, go, leave, arrive等表示位置移動的動詞常用現(xiàn)在進(jìn)行時表示將要發(fā)生的動作,它們很少與be going to 結(jié)構(gòu)連用。例如:
  Lucy is coming tonight.今晚露西要來。

  There be 結(jié)構(gòu)是英語中陳述事物客觀存的常用句型,表示“有”,其確切含義是“存在”there 作為引導(dǎo)詞,本身沒有意義,用動詞be的某些形式作為謂語動詞,它的主語是用一些表示泛指或不定特指的名詞詞組,動詞be和主語的數(shù)必須一致。句子最后通常為表示地點(diǎn)和時間的狀語。因此要表達(dá)“某個地方或某個時間存在什么事物或人”的時候常用
  “There be + 名詞+ 地點(diǎn)(時間)這一句型。例如:
  There is a bookstore across the street.
  穿過街道,有一家書店。
  There are some students in the classroom.
  在教室里有一些學(xué)生。
  一、There be 結(jié)構(gòu)中的主謂一致
  1.當(dāng)動詞be后所接的名詞是單數(shù)可數(shù)名詞或不可數(shù)名詞時,be 應(yīng)該取單數(shù)is;當(dāng)其后所接的名詞是復(fù)數(shù)的可數(shù)名詞時,be用復(fù)數(shù)are。
  There is a book on the desk.
  書桌上有一本書。
  There is some water in the bottle.
  瓶子里有些水。
  There are some eggs in the box.
  盒子里有一些雞蛋。
  2.如果There be 后面是幾個并列名詞做主語時,動詞be的形式和最靠近它的那個名詞保持?jǐn)?shù)的一致。
  There is an English book and two notes on the shelf. 架子上有一本英語書和兩個筆記本。
  There are notes and English book on the shelf. 架子上有兩個筆記本和一本英語書。
  二、There be 結(jié)構(gòu)在一般現(xiàn)在時態(tài)中的句子結(jié)構(gòu)
  1.肯定句:There be +名詞 +某處
  例如:There is a tree in the yard.在院子里有一棵樹。
  There is some water in the bottle.在瓶子里有一些水。
  There are some books on the desk.在書桌上有一些書。
  2.否定句:There be + not+名詞 +某處
  例如:There is not a tree in the yard.在院子里沒有樹。
  There is not any water in the bottle.在瓶子里有沒水。
  There are not any books on the desk.在書桌上沒有一些書。
  3.一般疑問句:be there +名詞 +某處
  例如:Is there a tree in the yard?在院子里有一棵樹嗎?
  --Yes, there is. (No, there isn't.)
  Is there any water in the bottle? 在瓶子里有一些水嗎?
  --Yes, there is. (No, there isn't.)
  Are there any books on the desk? 在書桌上有一些書嗎?
  --Yes, there are. (No, there aren't.)
  三、There be 結(jié)構(gòu)和have的區(qū)別與聯(lián)系
  1.區(qū)別點(diǎn):there be 意為存在,強(qiáng)調(diào)某地有某物,不表示所屬關(guān)系;have 表示所有關(guān)系,
  強(qiáng)調(diào)某人或某地有某物,這是其基本用法。如:
  There are some trees in front of the house.
  房前有些樹。
  Tom has many friends in China.
  湯姆在中國有許多朋友。
  2.相同點(diǎn):在表示結(jié)構(gòu)上的含有時,既可以用there be 句型,也可以用have(has) 來表示。如:
  中國有許多長河。
  There are many long rivers in China.
  China has many long rivers.
  三月份有多少天?
  How many days are there in March?
  How many days has March

  我們知道,some通常用于肯定句,any則用于常否定句或疑問句中。但隨著學(xué)習(xí)的深入,我們發(fā)現(xiàn),情況并不完全如此,上述說法只能算是對some和any用法的一個不太準(zhǔn)確和完整的概括。由于some和any是英語中比較常用的詞,我們有必要對其用法作出較完善的歸納。
  一、some和any作為形容詞或代詞,可以用來說明或代替復(fù)數(shù)名詞或不可數(shù)名詞,表示不定量,意為“一些”,其區(qū)別是:對其所說明或代替的名詞持肯定態(tài)度時,用some;持非肯定(否定或疑問)態(tài)度時,用any。
  在以下句子中使用some:
  1.肯定句(包括肯定的陳述句和祈使句以及反意疑問句中肯定的陳述部分)。如:
  There are some new books on the desk.
  I have a lot of sugar. Take some with you, please.
  He bought some apples, didn't he?
  2.持肯定態(tài)度的一般疑問句。如:
  Are there some eggs in the box?
  Didn't she give you some bread?
  3.表示請求或建議的一般疑問句,通常都希望得到對方肯定的答復(fù),所以也用some。如:
  May I ask you some questions?
  Would you like some tea?
  4.特殊疑問句及選擇疑問句。因?yàn)樘厥庖蓡柧浜瓦x擇疑問句并不對some所說明或代替的名詞表示疑問。如:
  Where can I get some buttons?
  Do you have some pens or pencils?
  在以下句子中使用any:
  1.否定句(包括否定的陳述句和祈使句以及反意疑問句中否定的陳述部分)。如:
  I don't have any money now.
  Do not make any noise.
  There weren't any trees here, were there?
  2.含有除not以外的其他否定詞或否定結(jié)構(gòu)的句子。如:
  Jim hardly makes any mistakes in his homework.
  He went to London without any money in his pocket.
  She was too poor to buy any new clothes.
  3.一般疑問句(持肯定態(tài)度的除外)。如:
  Did she buy any tomatoes yesterday?
  I want some paper. Do you have any?
  二、some還可表示“某些”或用在單數(shù)名詞前表示“某一個”。any則可用于表示“任何一些”或“(至少3個中)任何一個”,二者均可用于肯定或非肯定的句子中。如:
  I don't like some of them.
  He is working at some place in the north.
  Any criminal(s) will be punished.
  You can take any of these.
  三、some和any也可作為副詞,用于比較級前,表示程度,意為“稍許,幾分”,用法與其作形容詞或代詞表示“一些”時基本相同。如:
  He feels some better now.
  She was so tired that she could not go any further.
  some還可以用在數(shù)字之前,意為“大約”。如:
  He is some forty years old.

  文章類型:原創(chuàng) 發(fā)表于:2012/7/17 14:24:06
  一般過去式的用法:
  一般過去式 表示過去的動作和狀態(tài),通常一般過去式帶有表示動作時間狀語的詞,詞組或從句,如 yesterday, the day before yesterday, last week, two days ago ,last weekend等等,上下文清楚時可以不帶時間狀語。
  I worked in that factory last year. 去年我在那一家工廠工作。
  I met Lucy yesterday. 昨天我碰見了露西。
  We went to the Great Wall yesterday.
  昨天我們?nèi)チ碎L城。
  一般過去式構(gòu)成: 表示一般過去式的動詞通常用動詞的過去式形式來表示,而動詞的過去式是在動詞原形的基礎(chǔ)上變化的。
  動詞的過去式可分為規(guī)則動詞和不規(guī)則動詞。
  a.規(guī)則動詞的過去式變化如下:
 ?、僖话闱闆r下在動詞原形后直接加- ed。如:wanted,played, worked played ,acted, looked called opened needed。
  ②以不發(fā)音的字母e結(jié)尾的動詞,直接加-d。如:hoped,lived。
 ?、垡砸粋€輔音字母結(jié)尾的重讀閉音節(jié)動詞,雙寫詞尾輔音字母,再加 -  ed ,如: stopped planned fitted
  ④以輔音字母+y結(jié)尾的動詞變y為i,再加- ed。如:studied,, tried ,copied ,cried, 。
  以原音字母加y結(jié)尾的詞,直接加-ed play enjoy stay-- played enjoyed stayed
  規(guī)則動詞過去式的讀音也有規(guī)律可循。請記住:清后[t],元濁[d],[t] [d]之后讀[id]。
 ?、偾遢o音[p] [k] [f] [s]等后,ed要讀[t]。如:worked,finished。
 ?、谠艋驖彷o音[b] [g] [v] [z] [m]等后,ed要讀[d]。如:lived,called。
 ?、踇t]或[d]后,ed讀[id]。如:started,needed。
  b.不規(guī)則動詞變化
  不規(guī)則動詞的過去式變化規(guī)律性不強(qiáng),須多加記憶。
  1.動詞原形和過去式完全同形。
  例:  hurt(傷害) put(放) let(讓)
  2.動詞原形、過去式形式完全不同。
  例:  give(給) gave 、 fly(飛) flew  、drink(喝) drank  、see(看見) saw 、go(去) went 、 make - made 、get - got 、buy - bought 、come- came 、 know(知道)- knew 、 wear(穿) wore 、 speak(說) spoke、take-took、win-won、swim-swam、draw-drew
  be動詞過去式有兩種形式,主語是第一、三人稱(am/is)單數(shù)形式使用was,其他人稱(are)用were
  助動詞do/does的過去式為did
  3.動詞原形、過去式形式完全不同但讀音不同的。
  例如:read(【ri: d】)-  read  (【red】)
  不規(guī)則動詞的過去式平時出現(xiàn)要留心,逐個熟記,注意積累。
  一般過去式句子構(gòu)成:
  1.肯定句:主語+動詞的過去式形式+其他+過去的時間
  例如:We went to the bookstore yesterday.
  2.否定句:主語+ did +not+動詞原形+其他+過去的時間
  例如:We did not go to the bookstore yesterday.
  3.一般疑問句:Did + 主語 +動詞原形+其他+過去的時間
  例如:Did you go to the bookstore yesterday?
  --Yes, we did.  (No, we didn’t.)
