4、e.10. Whos on duty today?11. Lets do.12. Let me see.IV. 重要語法1. 動詞be的用法；2. 人稱代詞和物主代詞的用法；3. 名詞的單復數(shù)和所有格的用法；4. 冠詞的基本用法；5. There be句型的用法?！久麕熤v解】1. in/on 在表示空間位置時，in表示在某個空間的范圍以內，on表示在某一個物體的表面之上。例如： There is a bird in the tree. 樹上有只鳥。 There is a picture on the wall. 墻上有張圖。2. this/that/these/those (1)this常常用

5、來指在時間、地點上更接近講話人的人和事，these是this的復數(shù)形式。that常常用來指在時間、地點上離講話人更遠一點的人和事，those時that的復數(shù)形式。例如： You look in this box and Ill look in that one over there.你看看這個盒子，我去看那邊的那個盒子。 I want this car, not that car. 我想要這輛小汽車，不是那一輛。 Take these books to his room, please. 請把這些書拿到他房間去。 This is mine; thats yours. 這個是我的，那個是你的。

6、These are apples; those are oranges. 這些是蘋果，那些是橘子。 (2)在打電話的用語中，this常常指的是我，that常常指的是對方。例如： This is Mary speaking. Whos that? 我是瑪麗。你是誰？3. There be/ haveThere be 有，其確切含意為某處或某時存在某人或某物。其結構是：There be + 某人或某物 + 表示地點或時間的狀語。There be 后面的名詞實際上是主語，be 動詞的形式要和主語在數(shù)上保持一致，be動詞后面的名詞是單數(shù)或不可數(shù)名詞時用is，名詞是復數(shù)時用are。例如：(1) Ther

7、e is a big bottle of coke on the table. 桌上有一大瓶子可樂。(2) There is a doll in the box. 那個盒子里有個娃娃。(3) There are many apples on the tree. 那樹上有許多蘋果。總之，There be結構強調的是一種客觀存在的有。have表示擁有，占有，具有，即：某人有某物(sb. have / has sth.)。主語一般是名詞或代詞，及主語是所屬關系。例如：(4) I have two brothers and one sister.我有兩個兄弟，一個姐姐。(5) That house h

8、as four rooms.那所房子有四個房間。4. look/ see/ watch (1)look 表示“看、瞧”，著重指認真看，強調看的動作，表示有意識地注意看，但不一定看到，以提醒對方注意。，如：Look! The children are playing computer games. 瞧！孩子們在玩電腦游戲。Look! Whats that over there? 看！那邊那個是什么？單獨使用是不及物動詞，如強調看某人/物，其后接介詞at，才能帶賓語，如：Hes looking at me。他正在看著我。(2)see強調“看”的結果，著重的是look這個動作的結果，意思是“看到”，

9、see是及物動詞，后面能直接跟賓語。如：What can you see in the picture? 你能在圖上看到什么？Look at the blackboard. What did you see on it?看黑板！你看到了什么？(3)watch“觀看，注視”，側重于場面，表示全神貫注地觀看、觀察或注視某事務的活動，強調過程，常用于“看電視、看足球、看演出”等。如：Yesterday we watched a football match on TV.昨天我們從電視上看了一場足球比賽。4. put on/ / in put on意為“穿上，戴上”。主要指“穿上”這一動作, 后面接表

10、示服裝、鞋帽的名詞。in 是介詞，表示“穿著”強調狀態(tài)。在句中可以做定語、標語和狀語。如：Its cold outside, put on your coat. 外面冷，穿上你的外衣。He puts on his hat and goes out. 他戴上帽子，走了出去。The woman in a white blouse is Johns mother.穿白色襯衣的那個婦女是John的媽媽。5. house/ home/familyhouse ：“房子”，指居住的建筑物; Home: “家”，指一個人同家人共同經(jīng)常居住的地方; Family: “家庭“，“家庭成員”。例如：Please c

11、ome to my house this afternoon. 今天下午請到我家來。He is not at home. 他不在家。My family all get up early. 我們全家都起得很早。6. fine, nice, good, well四者都可用作形容詞表示好之意，但前三者既可作表語又可作定語，而后者僅用作表語。主要區(qū)別在于： (1) fine指物時表示的是質量上的精細，形容人時表示的是身體健康，也 可以用來指天氣晴朗。例如：Your parents are very fine. 你父母身體很健康。Thats a fine machine. 那是一臺很好的機器。Its a

12、 fine day for a walk today. 今天是散步的好時候。(2)nice主要側重于人或物的外表，有美好，漂亮的意思，也可用于問候或贊揚別人。例如：Lucy looks nice. 露西看上去很漂亮。These coats are very nice. 那些裙子很好看。Nice to meet you. 見到你很高興。Its very nice of you. 你真好。(3)good形容人時指品德好，形容物時指質量好，是表示人或物各方面都好的普通用語。例如：Her son is a good student. 她兒子是一個好學生。The red car is very good

13、. 那輛紅色小汽車很好。(4)well只可用來形容人的身體好，但不能作定語，它也能用作副詞作狀語，多放在所修飾的動詞之后。例如：Im very well, thanks. 我身體很好，謝謝。My friends sing well. 我的朋友們歌唱得好。【考點掃描】中考考點在本單元主要集中在：1. 動詞be的用法；2. 人稱代詞和物主代詞的用法；3. 名詞的單復數(shù)和所有格的用法；4. 冠詞的基本用法；5.

45、法；5一般現(xiàn)在時構成和用法；6可數(shù)名詞和不可數(shù)名詞的構成和用法【名師講解】1. Thats right./ Thats all right./ All right.Thats 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。Thats right.或 Youre right.說得對。Thats 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. Thats all right.Sorry. Its broken.

46、Thats 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？Hes doing his homework now.他正在做他的作業(yè)。3. say/speak/talk/t

47、ellsay：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，“我要坐汽車到那里去?！盤lease say it in English .請用英語說。speak : “說話”，著重開口發(fā)聲，不著重所說的內容，一般用作不及物動詞 (即后面不能直接接賓語 ) 。如：Can you speak about him? 你能不能說說他的情況？I dont 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匯

48、的能力。如：She speaks English well.她英語說得好。talk : 及 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(xù)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，一般后面總接雙賓語。如：Hes telling me a story.他在給我講故事。tell a l

49、ie 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 cookingdo 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(shù)，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

50、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. 及l(fā)ike to do sth. 意思相同，但用法有區(qū)別。前者強調一般性的愛好或者表示動作的習慣性和經(jīng)常性；后來表示一次性和偶然性的動作。例如：He likes playing football, but he doesnt like to play f

51、ootball with Li Ming.他喜歡踢足球，但是他不喜歡和李明踢。6. other/ others/ the other/ anotherother表其余的，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.在屋子里一些人是美國人,其他的是法國人。the other表另一個（二者之中）one，the otherOne of my two brothers studies English, the o

52、ther 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 treein the tree 及 on the tree.譯成中文均為在樹上但英語中有區(qū)別。in the tree表示某人、某事（不屬于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.

53、 那棵樹上有些蘋果。 There is a bird in the tree. 那棵樹上有只鳥。8. some/ any (1)some和 any既可修飾可數(shù)名詞，也可修飾不可數(shù)名詞。但有以下兩點需要 注意。some常用于肯定句中，any常用于否定句和疑問句中。如：There is some water in the glass.Is there any water in the glass?There isnt 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 som

54、e 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)說一個不及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)指建筑物、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)ta

55、ll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(jù)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？他會在什么地方呢？Can the news be true？這個消息會是真的嗎？It surely cant be six oclock already？不可能已

56、經(jīng)六點鐘了吧？You cant be hungry so soon，Tom，youve just had lunch.湯姆，你不可能餓得這么快，你剛吃過午飯。What can he mean？他會是什么意思？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，Im going now.我要走了，你坐我的座位吧。(3) couldcould 是 can的過去式，表示過去有過

57、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(yī)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(xiàn)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：C

58、ould you wait half an hour？請你等半個小時好嗎？Could you please ring again at six？六點鐘請你再打電話好嗎？(4) can的形式只有現(xiàn)在式can和過去式could兩種形式。能表示一般現(xiàn)在和一般過去兩種時態(tài)，有時也能表示將來。所有其他時態(tài)（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/ findlook for 意為“尋找”，而find意為“找到，發(fā)現(xiàn)”，前者強調“找”這一動作，并不注重

59、“找”的結果，而后者則強調“找”的結果。例如：She cant find her ruler. 她找不到她的尺子啦。Tom is looking for his watch，but he cant find it.湯姆正在尋找他的手表，但沒能找到。12. be sleeping/ be asleepbe sleeping 表示動作，意思是“正在睡覺”；be asleep 表示狀態(tài)，意思是“睡著了”。如：What are the children doing in the room? 孩子們在房間里做什么？They are sleeping.他們正在睡覺。The children are asl

60、eep now.現(xiàn)在孩子們睡著了。13. often/ usually/sometimesoften表示經(jīng)常，sometimes表示有時候，在表示發(fā)生頻率上often要高于usually，usually要高于sometimes。這三個詞表示的是經(jīng)常性，一般性的動作或情況，常及一般現(xiàn)在時連用，常位于主要謂語動詞的前面，其他謂語動詞（be動詞，情態(tài)動詞和助動詞）的后面，有時也可位于句尾。如果要加強語氣，則放在句首。 We usually play basketball after school.我們通常放學后打籃球。Sometimes I go to bed early.有時，我睡覺很早。He o
