I am twenty.  (2) are  第二人稱you+are; 一人稱複數we+are; 三人稱複數they+are 其他複數名詞+are (注意:第二人稱單複數同形,都爲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;其他單數名詞+is  例:HeShe is a good student. It is a white cat.  A dog is on that street.  2、肯定、否定、疑問(等於號後是簡寫)  肯定否定--be動詞後加not一般疑問--be動詞移到主語前一般疑問否定一般疑問回答 肯定和否定  I am… =I’m ….I am not…=I’m not I…?Am not I…?Yes,I’m. No,I’m not.

How much water in the bottle? -A little.-瓶子裏有多少誰呢?-一些。  How many (pictures) did you buy? 你買了多少幅(畫)?  四、與副詞連用  How fast does he drive? 他開得有多快?  How often do you go abroad? 你多長時間出一次國?  How badly was he hurt? 他傷得怎麼樣?  How soon can you come? 你多快能趕來?  注意How is she?(她身體怎麼樣?)詢問的是她的健康狀況,而What is she like?(她長得什麼樣?)詢問的是她的外貌。  另外,不要把How are you?(你身體怎麼樣?)和How do you do?(您好!)搞混。當兩個人被介紹認識時,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釐米高。  Lily: How about you? --你呢?  Me: I am 165cm. --我有165釐米高。  特殊疑問詞及特殊疑問句小結  特殊疑問句的兩種結構  1)與陳述句的詞序相同  ①疑問詞(who,what,which,whose)作主語  Who is there?誰在那兒?  ②疑問詞(what,which,whose)作定語用來修飾主語。  Which book is his?哪本書是他的?  2)疑問詞+一般疑問句的詞序  ①疑問詞作賓語  What are you Doing?你在幹什麼?  What are gonging to do this afternoon? 今天下午你打算幹什麼?  ②疑問詞作表語  Who is she?她是誰?  What is the time? 幾點了?  What color is the book? 那本書是什麼顏色?  What is the weather like today? 今天天氣怎麼樣?  What is the date today? 今天是幾月幾日?  What else? 其他還有什麼?  ③疑問詞作定語(其所修飾的成分是主語或賓語或表語)  Whose bag is that?那是誰的包?  ④疑問詞作狀語  How old are you?你多大年紀了?  1)疑問代詞  who誰 whom誰  whose誰的 which哪個,哪些  what什麼  2)疑問副詞(用作狀語)  when何時 where何地  Why爲什麼 how 如何  how much多少 how many多少  how long多久 how old多大年紀  how far多遠 how big多大  how often 幾次?  be going to 的用法總結  ·評論:0  ·瀏覽:780  ·RSS:0  文章類型:原創 發表於:2012/7/17 13:39:17  一、be going to 的用法點撥  be going to 是一種固定結構,它後面跟動詞原形,用來表示按計劃或安排要發生的動作或事件,有時也可以表示推測將要或肯定會發生的動作,有“準備;打算”的意思。含有be going to 結構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.看那些烏雲,快要下雨了。(推測)  二、be going to 在肯定句中的形式  be going to 結構中的助動詞be很少用原形,它一般有三種形式,即:am , is , are 。當主語是 I 時用am ;當主語是第三人稱單數時用is;當主語是第二人稱(you)或複數時用are。例如:  I am going to buy some books on Sunday.週日我打算去買些書。  She is going to visit her aunt and uncle this weekend.她打算這個週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.我們打算這個週末去參觀長城。  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  由於句子中有助動詞be,因此be going to 的否定句和一般疑問句的構成很容易,即在be (am, is, are) 的後面加上not 就構成了否定句;把be (am, is, are) 放到句首,在句末加問號就構成了一般疑問句,其答語爲:Yes, 主語+ am/is/are. / No, 主語+ isn't/aren't. / No, I'm not.不過 I am... 在改爲一般疑問句時常常改爲“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 應注意的兩點  1. There be 句型的be going to 結構爲:There is / are going to be... (注意句型中going to 後面的be不能改爲have。) 常用來表示將有某事發生。例如:  There is going to be a football match next Saturday in our school.下週六我們學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在進行時表示將要發生的動作,它們很少與be going to 結構連用。例如:  Lucy is coming tonight.今晚露西要來。  there be 句型用法總結  ·評論:0  ·瀏覽:196  ·RSS:0  文章類型:原創 發表於:2012/7/17 15:13:31  There be 結構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 作爲引導詞,本身沒有意義,用動詞be的某些形式作爲謂語動詞,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和主語的數必須一致。句子最後通常爲表示地點和時間的狀語。因此要表達“某個地方或某個時間存在什麼事物或人”的時候常用  “There be + 名詞+ 地點(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.  在教室裏有一些學生。  一、There be 結構中的主謂一致  1.當動詞be後所接的名詞是單數可數名詞或不可數名詞時,be 應該取單數is;當其後所接的名詞是複數的可數名詞時,be用複數are。  There is a book on the desk.  書桌上有一本書。  There is some water in the bottle.  瓶子裏有些水。  There are some eggs in the box.  盒子裏有一些雞蛋。  2.如果There be 後面是幾個並列名詞做主語時,動詞be的形式和最靠近它的那個名詞保持數的一致。  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 結構在一般現在時態中的句子結構  1.肯定句:There be +名詞 +某處  例如:There is a tree in the yard.在院子裏有一棵樹。  There is some water in the bottle.在瓶子裏有一些水。  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.在院子裏沒有樹。  There is not any water in the bottle.在瓶子裏有沒水。  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?在院子裏有一棵樹嗎?  --Yes, there is. (No, there isn't.)  Is there any water in the bottle? 在瓶子裏有一些水嗎?  --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 結構和have的區別與聯繫  1.區別點:there be 意爲存在,強調某地有某物,不表示所屬關係;have 表示所有關係,  強調某人或某地有某物,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:在表示結構上的含有時,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  some和any的用法總結  ·評論:0  ·瀏覽:402  ·RSS:0  文章類型:原創 發表於:2012/7/17 16:59:22  我們知道,some通常用於肯定句,any則用於常否定句或疑問句中。但隨着學習的深入,我們發現,情況並不完全如此,上述說法只能算是對some和any用法的一個不太準確和完整的概括。由於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作爲形容詞或代詞,可以用來說明或代替複數名詞或不可數名詞,表示不定量,意爲“一些”,其區別是:對其所說明或代替的名詞持肯定態度時,用some;持非肯定(否定或疑問)態度時,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覆,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。因爲特殊疑問句和選擇疑問句並不對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構的句子。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”或用在單數名詞前表示“某一個”。any則可用於表示“任何一些”或“(至少3箇中)任何一個”,二者均可用於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也可作爲副詞,用於比較級前,表示程度,意爲“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還可以用在數字之前,意爲“大約”。如:  He is some forty years old.  一般過去式時態的用法總結  ·評論:0  ·瀏覽:436  ·RSS:0  文章類型:原創 發表於: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,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.  昨天我們去了長城。  一般過去式構成: 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上變化的。  動詞的過去式可分爲規則動詞和不規則動詞。  a.規則動詞的過去式變化如下:  ①一般情況下在動詞原形後直接加- ed。如:wanted,played, worked played ,acted, looked called opened needed。  ②以不發音的字母e結尾的動詞,直接加-d。如:hoped,lived。  ③以一個輔音字母結尾的重讀閉音節動詞,雙寫詞尾輔音字母,再加 - ed ,如: stopped planned fitted  ④以輔音字母+y結尾的動詞變y爲i,再加- ed。如:studied,, tried ,copied ,cried, 。  以原音字母加y結尾的詞,直接加-ed play enjoy stay-- played enjoyed stayed  規則動詞過去式的讀音也有規律可循。請記住:清後[t],元濁[d],[t] [d]之後讀[id]。  ①清輔音[p] [k] [f] [s]等後,ed要讀[t]。如:worked,finished。  ②元音或濁輔音[b] [g] [v] [z] [m]等後,ed要讀[d]。如:lived,called。  ③[t]或[d]後,ed讀[id]。如:started,needed。  b.不規則動詞變化  不規則動詞的過去式變化規律性不強,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)單數形式使用was,其他人稱(are)用were  助動詞do/does的過去式爲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】)  不規則動詞的過去式平時出現要留心,逐個熟記,注意積累。  一般過去式句子構成:  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.)  ·  · <>
