教學(xué)建議

教學(xué)內(nèi)容分析

本單元的教學(xué)核心是關(guān)于孩子們參觀小島（A visit to an island）的這件事。圍繞這個核心安排了三個對話和兩篇短文，集中反映了孩子們上島前所做的準(zhǔn)備工作（約會、帶食品、約定出發(fā)的時間，討論去哪一個島等）及在島上的所見所聞，情節(jié)跌宕起伏，有一定的傳奇色彩。在整個內(nèi)容的安排中引出了本單元要學(xué)習(xí)的功能項目“推測”（Conjecture）、求助（Calling for help）和動詞take，bring的區(qū)別及不定代詞和不定副詞的用法。

在第73課中有兩段對話，主要描述孩子們在上島前所做的準(zhǔn)備工作及討論去哪一個島。從而引出英語中表示距離遠(yuǎn)近的表達(dá)法。如：Why don’t we go to the farther one?/ How about the farthest one？/The smaller one is nears．這兩段對話為下節(jié)課做了內(nèi)容上的鋪墊。

第74課和第75課的第一部分及第76課的第一部分事實上是一個故事的整體，具體描繪了孩子們在島上的所見所聞，表現(xiàn)了孩子們新奇、緊張、害怕交叉在一起的復(fù)雜心情。第76課中關(guān)于一群猴子企圖偷吃籃子里食物的一段描寫頗為生動。第75課的第二、三部分著重練習(xí)不定代詞和不定副詞的用法。第76課的第四部分是提示性的寫作訓(xùn)練。主要是對課文的模仿和對所學(xué)內(nèi)容的實際運用。教師可以作一些適當(dāng)?shù)慕忉�。第五部分是一首小詩�?/p>

重難點及疑點分析

重難點：

1. no longer=not any longer, not any more. no longer與系動詞be連用時置于系動詞be的后面，與行為動詞連用時放在行為動詞的前面，如：

1) He is no longer a worker. =He isn't a worker any longer/any more. He’s an engineer now.

2) He no longer lives here. =He doesn't live here any longer/any more. He’s living in another city.

2.There’s something wrong with your ears.

There + be + something/nothing wrong with. . .是一個固定的句型，意思是“…出/沒毛病（問題）。它的同義句是Something/Nothing + be wrong with. . .如：

1) There is something wrong with your computer. =Something is wrong with your computer. It’s not working now.

2) There is nothing wrong with the new bike. =Nothing is wrong with the new bike. It’s quite OK.

疑點：

1.短語too…to

too…to句型的意思是“太……以致不能……”，too是副詞，后面接形容詞或副詞，to是動詞不定式的標(biāo)志，后接動詞原形。該句型雖然沒有否定詞not或no，但具有否定的意義。若需要加上人稱，則在不定式之前加for sb。如：

1) The sentence is too difficult to understand. Please give me an easy one.

2) These apples are too high for us to reach. We’d better get a ladder.

2.We'd better not go there. It’s too far from here.

had better后面接動詞原形，其否定形式是had better no+動詞原形。had不受人稱限制，不可以說have／has better。如：

Girls had better not go out at night. They had better stay at home.

2. We’ve never been there before.

該句型 have; has been to+地點名詞表示某人曾去過某地，現(xiàn)在已離開那個地方或已回來。若地點是副詞則“to”省略。如：

We have never been to Shanghai. But they have been there for three times. They can tell us a lot about Shanghai.

3. We won't go until we get it back again!

本句中的until作連詞，引導(dǎo)一個時間狀語從句。not…until意為“直到……才”，“在……之前不……”，主句中的謂語動詞一般是非延續(xù)性動詞，如leave，finish，begin，go，start等，until引導(dǎo)的時間狀語從句中將來時用一般現(xiàn)在時表示。如：

They won't leave their school until their teacher returns. They will ask the teacher many questions until they are able to do these exercises.

   [4] [5]   

口語訓(xùn)練

本單元的口語訓(xùn)練主要包括兩項內(nèi)容①表示距離遠(yuǎn)近的用法。②不定代詞和副詞的用法。

1．表示距離遠(yuǎn)近的用法

在學(xué)生熟練掌握第73課第二部分內(nèi)容的基礎(chǔ)上，先回憶一下以前學(xué)生用書中所出現(xiàn)的一些有關(guān)距離的表示法。如How far is it？/ Is it far？/ It’s/quite near．／It’s about…kilometers farthest（furthest）等。同時復(fù)習(xí)一下far這個詞的不規(guī)則比較級形式和最高級形式。far→farther（further）→farthest（furthest），告訴學(xué)生near（close）的比較級和最高級形式的變化是規(guī)則的。老師可以給學(xué)生一些提示，讓學(xué)生相互之間展開由易到難的練習(xí)。

（1）編制一些簡單的問句問學(xué)生。如：

How far is it from your home to school? Is it near from your home to your uncle’s? Is our school far from People Park? Where’s the shopping center?等。

（2）編制一段對話。如：

Lucy: Hi, Li Lei! Where are you going this summer holiday?

Li Lei: My father will take me to Nanjing.

Lucy: How wonderful! Nanjing is an old but beautiful city. How far is it from here?

Li Lei: It's about 360 kilometres. What about you?

Lucy: I’m going to Shanghai with my uncle to see my grandfather. He works there.

Li Lei: How far is it from here? Is it nearer or farther than Nanjing?

Lucy: It's nearer. It's about 180 metres.

A: Which city do you like best, Qingdao, Nanjing or Hangzhou?

B: I like Hangzhou best.

A: Is Hangzhou near here?

B: No, It’s far from here. It’s about 210 kilometres away.

A: What about Nanjing?

B: It's farther. It’s 600 kilometres away.

A: And Qingdao?

B: It’s the farthest. It’s nearly 1000 kilometres away.

2．不定代詞和副詞的用法

在第74課及第75課中出現(xiàn)了不定代詞和副詞的用法。在第75課中更為集中，首先對一些不定代詞作一些歸納。列表如下：

somebody

someone

something

somewhere

anybody

Anyone

anything

anywhere

nobody

no one

nothing

nowhere

上一頁     [4] [5]   

然后告訴學(xué)生這些詞都是由some，any或no與body，thing，one或where構(gòu)成的合成詞，一般情況下，somebody, something, somewhere用于肯定句，而anybody, anything, anywhere用于否定句、疑問句及條件句中。如：

(1)I can see something on the wall. Is it a new painting?

(2) Somebody is knocking at the door. Go and have a look.

(3) Yesterday Han Mei found her pen somewhere. Now she still doesn’t know who put it there.

(4) Can you hear anything in the next room? Somebody is crying.

（5) –Is there anybody running on the playground?

–Yes, it’s Wang Tong.

(6) I can't see anybody in the teacher's office. But I must ask the teacher an important question.

(7) They didn't go anywhere, because it was raining heavily. They played ping-pong in the classroom.

但也有例外情況。當(dāng)表達(dá)請求、建議、反對等肯定意圖時，something, somebody等詞也可用于疑問句形式。如：

(8) – Is somebody coming this evening?

–Yes, But I don’t know who’s coming.

(9) Would you please give me something to eat? Certainly. Help yourself to anything in the ice box.

教師可通過實物教學(xué)或創(chuàng)設(shè)情景教學(xué)，讓學(xué)生在情景中學(xué)習(xí)并掌握不定代詞或副詞的運用。如教師可利用教室中的物品：box, bag等進(jìn)行活動。

A: Can you see anything in the box?

B: No, I can’t. It’s closed.

C: I think there is something in it.

B: I don’t think so. Let’s open it. Maybe there’s nothing in it.

還可以出示圖片假設(shè)情景：孩子們在春游，看見遠(yuǎn)處樹叢中樹葉晃動。

A: Look! Can you see anything over there?

B: No, I can’t see anything.

A: Nothing? Look carefully and you’ll see something in the trees.

B: Sorry I can’t. Something is wrong with my eyes.

A: There’s nothing wrong with your eyes, I think. Look again and you’ll see it.

B: Oh, yes. Something is moving in the tree. It’s a yellow bird!

鞏固性練習(xí)：在學(xué)生了解不定代詞基本用法的基礎(chǔ)上指導(dǎo)學(xué)生做練習(xí)冊第87頁上的練習(xí)2，教師也可以適當(dāng)補充一些課外練習(xí)來進(jìn)一步加以鞏固。

教學(xué)take和bring的用法

take和bring都有“拿”和“帶”的意思。學(xué)生在實際運用中容易混淆。一般來說take是把東西拿到離開說話人所說話的地方。表示“拿走”或“帶走”。而bring則表示把東西拿到說話人所說話的地方，是“拿來”，“帶來”的意思。用圖表示：

教師可以設(shè)置一些具體的情景，讓學(xué)生進(jìn)行練習(xí)。如：

A: Where’s your homework, Wang Ming?

B: Sorry, I left it at home.

A: Bring it here tomorrow.

B: OK.

A: By the way, whose chair is it?

B: Our teacher's.

A: Please help me take it to the teacher’s office.

B: All right.

A: Thanks a lot.

B: You re welcome.

take sth．with sb．表示隨身帶走某物，bring sth．with sb．則表示隨身帶來某物。take sth．a(chǎn)way表示拿走某物。試比較：

It is going to rain, please take your raincoat with you.

When you come here next time, please bring the raincoat with you. Please take the empty box away.

閱讀訓(xùn)練

本單元安排了兩篇閱讀短文，比較詳盡地描述了孩子們在島上的經(jīng)歷及所見所聞，情節(jié)跌宕起伏。初中學(xué)生有極強的好奇心，對課文內(nèi)容一定很感興趣。在組織學(xué)生閱讀前，老師可以先解釋一些難點，如no longer，all by oneself，not…until，look over等，為學(xué)生快速閱讀掃除障礙。閱讀后老師用"Yes" or "No"回答的一般疑問句提問學(xué)生，以加深他們對課文內(nèi)容的理解。最后老師可以把按故事情節(jié)設(shè)置的幻燈片或簡筆畫展示給學(xué)生，讓他們根據(jù)圖示用英語講出故事的主要情節(jié)。使閱讀和口頭訓(xùn)練有機地結(jié)合在一起，教學(xué)效果一定會更好。

教學(xué)指導(dǎo)

1．本單元出現(xiàn)了不少常用的短語，必須要熟記并會運用。

bring food for a picnic/be late for/had better not to do sth./have never been to/pull sth. out of/look I around/keep sth. cool/all by oneself/no longer/not. . .until/get sth. back/look over/run after( away)

2．在老師的指導(dǎo)下，通過一定量的口頭和書面訓(xùn)練，反復(fù)訓(xùn)練不定代詞/副詞something, anything, somebody, anybody, somewhere, anywhere的用法，熟練掌握不定代詞和副詞的用法，take和bring的用法。

能力訓(xùn)練點

3．本單元的主題是“參觀小島（A visit to an island）”。在學(xué)生熟練掌握課文內(nèi)容的基礎(chǔ)上，老師可給學(xué)生提供一定量的詞匯和短語，要求他們模仿課文內(nèi)容寫一篇游記性質(zhì)的小短文。

復(fù)合不定代詞、副詞

some-, any-, no-（no one例外）, every-與-one, -thing, -body, -where（副詞）構(gòu)成復(fù)合不定代詞或副詞。復(fù)合不定代詞可以代替一般數(shù)量的名詞，在句中作主語、賓語、表語等。

一般情況下，some構(gòu)成的復(fù)合不定代詞，其作用和some相同，用于肯定句：any構(gòu)成的復(fù)合不定代詞用于否定或疑問句；no構(gòu)成的復(fù)合不定代詞其作用和any相同，用于否定句。如：

I have something to tell you. 我有事要告訴你。

He didn’t say anything at the meeting yesterday. 昨天在會上他沒有發(fā)言。

Everybody likes swimming. 每個人都喜歡游泳。

使用復(fù)合不定代詞、副詞應(yīng)注意以下幾點：

1．復(fù)合不定代詞被形容詞修飾時，復(fù)合不定代詞要放在形容詞之前。如：

There’s something new in today’s paper. 今天的報紙上有些新內(nèi)容。

2．復(fù)合不定代詞被動詞不定式（短語）修飾時，不定式（短語）要后置。如：

I have something to tell you.  我有些話要告訴你。

3．復(fù)合不定代詞在句中作主語時，謂語動詞一般用單數(shù)形式。如：

I hope everything goes well．我希望一切順利。

Nothing is too difficult for you in the world if you put your heart into it. 世上無難事，只怕有心人。

4．復(fù)合不定代詞作主語，變成反意疑問句時，要看不定代詞是指人還是指物：指人時，附加問句的主語用they或he（人稱與數(shù)一致）；指物時附加問句的主語要用it。如：

Someone is knocking at the door, isn't he? 或aren't they?有人在敲門，對嗎？

Everything begins to grow in spring, doesn't it? 春季萬物開始生長，對不對？

5．含no的復(fù)合不定代詞相當(dāng)于“not + any的復(fù)合不定代詞”。如：

I saw nothing in the room. =I didn't see anything in the room．我在屋子里什么也沒看見。

6．復(fù)合不定副詞在句中只能作狀語，常放在句尾。如：

I can't find it anywhere．我在什么地方都找不到它。

[注意事項］通常情況下，含some-的復(fù)會不定代詞、副詞用在肯定句中，但在表示請求、建議等委婉說法的疑問句中，或期望得到肯定答復(fù)的疑問句中，也用some-，不用any-。如：

Would you like something to drink？ 你想要些喝的嗎？

Can you find it somewhere?  你能在某個地方找到它嗎？

[練習(xí)]從下列各題后所給的選項中選擇最佳答案填空。

1. –Do you have _____to say for yourself?

–Yes, it is this.

A. something    B. anything   C. everything   D. nothing

2. –Everyone is here today, _____?

–No, Han Mei isn’t here. She’s ill.

A. isn't it       B. isn't he   C. are they     D. isn’t everyone

3. There’s _____with his eyes. He’s OK.

A. are      B. is      C. be     D. were

5. What about_____? I’m so hungry.

A. anything to eat    B. to eat something   C. something to eat   D. to eat anything

疑難解析

1. Are you coming with us? 你和我們一起去嗎？

這是現(xiàn)在時表示將來動作的用法。英語中類似come，go，fly, arrive, leave, start等表示位置移動的動詞的現(xiàn)在進(jìn)行時態(tài)可用來表示按計劃安排將要發(fā)生的事。如：

My father is going to Shanghai tomorrow. I’m going to see him off at the station.

John is coming here next week and will stay here until May. So he is coming to see us the day after tomorrow.

I'm seeing her tomorrow. She’s in hospital.

What are you doing next Saturday? We’re going to visit a museum.

2. Which island shall we go to first？我們先去哪個島？

句中的介詞to不可以省略。從語法邏輯看，which island作后面動詞的賓語。而go是不及物動詞，不能直接跟賓語，只有加上介詞to才能與which island構(gòu)成完整的動賓搭配。類似的還有wait for等。如：

–Who are you waiting for？

–I’m waiting for you. May I have a talk with you?

3. We’ve never been there before.我們以前從未去過那兒。

have been to+地點表示“曾經(jīng)去過某地(現(xiàn)在已回來)。have gone to+地點表示“某人去某地了(現(xiàn)在不在這兒)”。如：

(1) —Where have you been? 你去過哪里?

  —I have been to Shanghai. 我去過上海。

(2) —Where is she? 她去哪兒了?

—She has gone to the library. 她去圖書館了。

4. We’re all by ourselves.就我們這些人。

by oneself 意思是“單獨的，獨自的”。all修飾by oneself，起加強語氣的作用。如：

I learned English all by myself. My teacher is the recorder.

5. The picnic basket was no longer under the tree.

no longer 表示“不再”，與not…any longer同義，強調(diào)時間。no more也表示“不再”，與not…any more同義，強調(diào)數(shù)量。原句還可以說為：The picnic basket wasn’t under the tree any longer. 如：

I don’t want wine any more. It’s more than enough.

6. Sooner or later you’ll find it somewhere.

句中的sooner or later意思是“遲早”，其中and前后的sooner和later為互為反義詞。英語中這種短語還有一些，下面幾組比較常見：

back and white 白紙黑字  every now and then 不時，時時

here and there 到處   off and on斷斷續(xù)續(xù)

days and nights 日日夜夜  more or less或多或少

7. As they were very hungry，they ate up all the food soon. 因為他們很餓，所以他們很快就把食物吃光了。

1）as引導(dǎo)一個原因狀語從句。它與because的區(qū)別是：前者表示的原因只是附帶說明，無強調(diào)客觀之意，不能回答why提出的問題；后者著重強調(diào)客觀原因，用于回答why提出的問題。例如：

We all like her as she is kind. She’s kind to everybody.

As it was dark, he had to go home. Or his mother would be worried.

2）eat up意思是‘吃光”。up與某些動詞連用時，表示“完全，徹底”的意思。常見的幾個詞組有：drink up喝光；use up用完；clean up除掉，把……收拾干凈。如：

Please eat up your chicken. You need to eat more as a big boy.

Drink up your milk before you go to school. It’ll do good to you.

8. Children took them back to the boat. 孩子們把它們帶回船上。

take back為動副詞組。在“動詞 + 副詞”短語中，當(dāng)人稱代詞充當(dāng)它的賓語時，人稱代詞不能置于副詞之后，只能放在動詞和副詞之間。類似的短語還有l(wèi)ook over，wake up，get back，put on等。如：

Please wake me up tomorrow morning. I’ll have to get to school half an hour earlier.
