第一篇：新概念3第一課

Lesson 1: A puma at large

Pumas are large cat-like animals which are found in America.When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously.However, as the evidence began to accumulate, experts from the zoo felt obliged to investigate, for the description given by people who claimed to have seen the puma were extraordinarily similar.The hunt for the puma began in a small village where a woman picking blackberries saw a large cat only five yards away from her.It immediately ran away when she saw it, and experts confirmed that a puma will not attack a human being unless it is cornered.The search proved difficult, for the puma was often observed at one place in the morning and at another place twenty miles away in the evening.Wherever it went, it left behind it a trail of dead dear and small animals like rabbits.Paw points were seen in a number of places and puma fur was found clinging to bushes.Several people complained of cat-like noises at night, and a businessman on a fishing trip saw the puma up a tree.The experts were now fully convinced that the animal was a puma, but where had it come from? As no puma was reported missing from any zoo in the

country, this one must have been in possession of a private collector and somehow managed to escape.It is disturbing to think that a dangerous wild animal is still at large in the quiet countryside.

VI Teaching procedures Step1 Greeting and warm up

T:Hello,everybody,boys and girls,how are you today? S:fine,thanks,and you? T:I am fine too,thank you 1 T:welcome to the new concept English book three,developing skills ,I am MR Wang from the TT elite , It’s really great pleasure to be with you in this course ,I hope you will find your study to be great progress;大家好，下邊就由我來為大家講授新概念英語第三冊，第三冊的標題是 developing skills，就是說這一冊的學習者應當具有一定的基礎才談得上發展和提高，那么基礎的標準是什么呢，大致來說就是英語中等水平，無論你是否學習過這套教材的前一、二冊，只要你認為你已經具備或大體具備英文的中等水平，都可以從這一冊開始學習，what skill should you develop?briefly speaking,it’s language proficiency in listening speaking、reading and writing , 熟練的掌握這四項基本技能，是為了提高我們常說的語感，我們還是會從一篇一篇的小故事開始，就像這套教材的作者亞歷山大強調的，一篇有趣的故事可以提供一個活的語言環境，這樣我們學習到的就不是孤立的字詞，而是語言在具體環境當中的交流和實際應用，和語言后面潛在的文化信息.Step2 Lead in and presentation T:And now let’s start from the beginning ,;Lesson1:A puma at large，This lesson is about an escaping puma, 這課講的是一頭正在逃遁的美洲獅，first，listen to me read the text carefully，and see if you can answer this question:where must the puma have come from? T:Pumas are large, ‘cat-like animals’ which are found in America.When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously.However, as the evidence began to accumulate, experts from the Zoo felt obliged to investigate, for the descriptions given by people who claimed to have seen the puma were extraordinarily similar.The hunt for the puma began in a small village where a woman picking blackberries saw a large cat only five yards away from her.It immediately ran away when she saw it, and experts confirmed that a puma will not attack a human being unless it is cornered.The search proved difficult, for the puma was often observed at one place in the morning and at another place twenty miles away in the evening.Wherever it went, it left behind it a trail of dead deer and small animals like rabbits.Paw prints were seen in a number of places and puma fur was found clinging to bushes.Several people complained of ‘cat-like noises’ at night and a businessman on a fishing trip saw the puma up a tree.The experts were now fully convinced that the animal was a puma, but where had it come from ? As no pumas had been reported missing from any zoo in the country, this one must have been in the possession of a private collector and somehow managed to escape.The hunt went on for several weeks, but the puma was not caught.It is disturbing to think that a dangerous wild animal is still at large in the quiet countryside.T:So where must the puma have come from?注意這里用的是must have come from ,must 它的基本詞義是必須，但是它在這里表達的是一種 推斷和猜測,我們再回到這個問題，where must the puma have come from？the text tells us that the puma must have escaped from the private collection,y也就是說這頭美洲獅是一個私人豢養的，這個結論呢是在有呢很多線索之后得到的，整篇課文給我們講述的是越來越充實的證據（accumulating evidence），講述的是專家們由不太當真(not taken seriously)到不得不去調查（felt obliged to investigate），到最后完全肯定的一個過程（fully convinced），那么這些證據究竟有哪些？又是怎樣影響了專家們的看法，請同學們在學習中理清課文的這些脈絡。T:Now let’s look at some language points in the text T:A puma at large

T:Be at large(潛逃),Who can give me an example of this expression? S:有學生舉手，多叫幾名同學，然后老師也可以給一個： The escaped prisoners are still at large（逃犯還沒有落網）T:這篇課文在幾處都出現了表示看或看見的詞語，When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London……

People who claimed to have seen the puma…… The puma was often observed at one place……

T:表示看見這個意思，see是最常用的詞，而 observe要比see更加書面化，spot means to notice something very difficult to see ,or find something being looked for 表示看到了不太容易看到的東西，或者發現了正在尋找的東西。Who can give me an example? S:請學生回答；老師給出例子

I spotted someone coming out of the building

T:as the evidence began to accumulate, experts from the Zoo felt obliged to investigate……Accumulate means to gradually increase over a period of time 指的是逐漸增加或積累

T:feel obliged to 這是一個固定詞組，經常用來做書面語，must，have to，have a duty to do 必須有義務、責任做……事前 S:請學生回答并給出例子eg：I felt obliged to invite him

T:The hunt for the puma began in a small village where a woman picking blackberries saw a large cat;Hunt 捕獵 搜尋

T:請同學翻譯go on a deer /fox hunt 獵（鹿、狐）；The hunt for the remains of the titanic（搜尋TITANIC殘骸）；Hunt for second-hand book（搜尋二手書）；Job-hunting（找工作）T:Pick采摘；Pick cotton摘棉花；

S:請學生翻譯We need to pick someone reliable 挑選我們要找一個可靠的人

T:Pick and choose 挑挑揀揀

T:A puma will not attack a human being unless it is cornered;Cornered 陷入困境 被逼得走投無路

T:The search proved difficult;Prove=turn out to be 證明是 原來是VI S:請學生翻譯They proved her innocence

他們證實了她是無辜的（證實VT）；The rumour proved false 謠言證明是錯誤的； Puma fur was found clinging to bushes ；

T:Cling-clung-clung 過去式過去分詞;Cling to 粘住

S:學生翻譯His wet shirt clung to his body ；She clings to the belief that her Husband will come back 堅持固執的相信

T:Some people complained of ‘cat like noises’ at night ……表示報告或者是述說,表示一種不滿的情緒

T:complain跟的介詞不同意思也不同complain about the weather 抱怨天氣不好;complain of a headache 述說自己頭疼

T:It is disturbing to think that a dangerous wild animal is still at large in the quiet countryside

worrying令人擔憂的不安的

T:Disturb 打攪 Sorry to disturb you 對不起打擾你了;Do not disturb

His strange behaviour disturbed me 他舉止反常讓我很擔心

T:However, as the evidence began to accumulate, experts from the Zoo felt obliged to investigate, for the descriptions given by people who claimed to have seen the puma were extraordinarily similar.T:大家都知道 在英文中基本的句型就是簡單句 并列句以及復雜句，就是我們經常聽到的simple sentences

compound sentences complex sentences,這篇課文主要是有復雜句構成的，now look at sentence please ,要理解一個復雜句，最重要的是要搞清句子的結構，然后通過連接詞，分清主句和從句之間的關系，就是說要把握主句和從句的位置，而主句和從句的關系是由連接詞來判斷的，在這個句子當中，主句就是experts from the Zoo felt obliged to investigate，主句前邊有一 個as引導的從句，他表示的是一種伴隨主句同時發生的狀態，它的后邊又有一個for引導的從句來交代原因，而這個從句當中有一個given，它起的實際上是一個定語從句的作用，用來修飾 descriptions，如果用從句來表達就是which had been given by people，而這個從句當中由套著一個從句，是由who來引導的，用來修飾people，所以一個句子結構不論有多么復雜，只要我們能把握連接詞，在句子當中的作用，和意思，就不難理解。

T:When reports came into London Zoo that a wild puma had been spotted;the puma was often observed at one place in the morning and at another place;Paw prints were seen…… puma fur was found clinging to bushes;As no pumas had been reported missing from any zoo in the country

T:當英文中表示一個事實的客觀性的時候往往用被動語態，這篇課文就是這樣講的是美洲獅 在各處出現并且被人目擊的情形，我們來看看被動語態在課文當中的使用：had been spotted，was …… observed，were seen……，was found clinging，had been reported missing;另外was found clinging

had been reported missing 是在被動語態之后加上現在分詞，起補充說明主語的作用

T;我們知道了西方有收集動物的人，在我們中國現在呢也有喂養寵物的人……

Step 3 Consolidation and homework T: Today we learned some new words and expressions , Who are they? Homework: 1.listen to the tape of lesson one 2.Read the text and recite to your parents and me.

第四篇：新概念第一冊第一課教案

1.Excuse me!這是常用于表示道歉的客套話，相當于漢語中的“勞駕”、“對不起”。當我們要引起別人的注意、要打攪別人或打斷別人的話時，通常都可使用這一表達方式。在課文中，男士為了吸引女士的注意而使用了這句客套話。它也可用在下列場合：向陌生人問路，借用他人的電話，從別人身邊擠過，在宴席或會議中途要離開一會兒等等。2.Pardon？對不起，請再說一遍。

當我們沒聽清或沒理解對方的話并希望對方能重復一遍時，就可以使用這一表達方式。較為正式的說法是：

I beg your pardon.I beg your pardon?

Pardon me.它們在漢語中的意思相當于“對不起，請再說一遍”或者“對不起，請再說一遍好嗎？” 3.語法

be動詞有am，is，are

am只能跟在第一人稱的單數I后面 is 跟在第三人稱單數he，she后面

be動詞的基本意思：是 re搭配you，不管是單數還是復數

you are，we are，they are

I am---I’m she is---she’s

he is---he’s

it is---it’s

you are---you’re

we are---we’re

they are---they’re

含有be動詞的簡單的陳述句，否定句，一般疑問句

This is my handbag.這是我的手提包。

含有be動詞的句子如果變否定句，就是在be動詞后面加not

This is not my handbag.這不是我的手提包。

含有be動詞的句子，如果變一般疑問句，就把be動詞提到句子的前面，大寫

Is this my handbag? 這是我的手提包嗎？

Is this your handbag?

book 書本 watch手表 pen鋼筆 car小汽車

Yes, it is.是的。

No, it isn’t.不是。

This is my book.這是我的書。

This is not my book.這不是我的書。

Is this your book? 這是你的書嗎？

Yes, it is.是的。

一般疑問句

首先我們要弄懂什么是一般疑問句式。當我們想說“你是??嗎?”,“你做??了嗎?”的時候,就要用一般疑問句式。為了便于同學們學習,我分類講解一下一般現在時的一般疑問句式。

一、含有be動詞的一般疑問句,通常把be動詞調到句首。

二、例如: 陳述句:They are in the swimming pool.一般疑問句:Are they in the swimming pool? Yes, they are./No, they aren’t.三、含有have的一般疑問句,have譯為“有”。一般疑問句式有兩種形式: 1.把have/has調到句首。例如: 陳述句:Tommy has a computer.一般疑問句:Has Tommy/he a computer? 2.加助動詞do/does,第三人稱單數用does,其他人稱用do。其句型為:Do/Does + 主語 + have...?例如上句可變為: Does Tommy have a computer? Yes,he does./No, he doesn’t 一、一般疑問句含be動詞時,用be動詞回答,句末用句號。例如:-Is Mary your sister?-Yes, she is./ No, she isn’t.(縮寫)三、一般疑問句含有have(譯為“有”)時,有兩種回答方式。1.直接用have/has回答。例如:-Have they any pictures?-Yes, they have./ No, they haven’t.2.用助動詞do/does回答。例如:-Does Millie smoke?-Yes, she does./ No, she doesn’t.1．將陳述句變為一般疑問句時，如句中有be 動詞（am is are ?）時，可直接將它們提至主語前。

2．如主語為第一人稱，應將其改為第二人稱。如： I'm in Class 2Grade 1． → Are you in Class 2，Grade 1？ We're watching TV． → Are you watching TV？ 3.一般疑問句有時不用yes或 no 回答。

如： Are they in town now？ I think so.May I sit here？ Certainly． Does he like soccer？ Sorry，I don't know．

5.人稱代詞

主格

賓格 形容詞性的物主代詞 名詞性的物主代詞

我（們）I

me

my

mine

你（們）you you

your

yours

他（們）he

him

his

his

她（們）she

her

her

hers

This is my pen.這是我的鋼筆。

This pen is mine.這只筆是我的。

6.My life is brilliant.我的人生繽紛燦爛。My love is pure.我的愛如此純真。

I saw an angel.因為我見過天使。Of that I'm sure.對此,我深信不疑。You're beautiful.You're beautiful, 你就是這么美，你就是這么美，You're beautiful, it's true.你就是這么的美，這是千真萬確。

I saw your face in a crowded place, 我曾在人潮擁擠之處瞥見你的臉，And I don't know what to do, 這令我不知所措。

'Cause I'll never be with you.因為我和你永遠無法相依。Yeah, she caught my eye, 是啊,我視線被她占據。

She could see from my face that I was, 她應該可以從我的神情看出，flying high, 我欣喜若狂飛上云霄，And I don't think that I'll see her again, 我想,我將再也見不到她。

But we shared a moment that will last till the end.但我們共享了永恒的片刻。There must be an angel with a smile on her face, 我看到了笑起來跟她一模一樣的天使，When she thought up that I should be with you.當她也想到我們應該在一起時。But it's time to face the truth, 但，該是面對事實的時候了，I will never be with you.我和你永遠無法相依。

T:Hello,everybody,boys and girls,how are you today? S:fine,thanks,and you? T:I am fine too,thank you 1 T:welcome to the new concept English book three,developing skills ,I am MR Wang from the TT elite , It’s really great pleasure to be with you in this course ,I hope you will find your study to be great progress;大家好，下邊就由我來為大家講授新概念英語第三冊，第三冊的標題是 developing skills，就是說這一冊的學習者應當具有一定的基礎才談得上發展和提高，那么基礎的標準是什么呢，大致來說就是英語中等水平，無論你是否學習過這套教材的前一、二冊，只要你認為你已經具備或大體具備英文的中等水平，都可以從這一冊開始學習，what skill should you develop?briefly speaking,it’s language proficiency in listening speaking、reading and writing , 熟練的掌握這四項基本技能，是為了提高我們常說的語感，我們還是會從一篇一篇的小故事開始，就像這套教材的作者亞歷山大強調的，一篇有趣的故事可以提供一個活的語言環境，這樣我們學習到的就不是孤立的字詞，而是語言在具體環境當中的交流和實際應用，和語言后面潛在的文化信息.Step2 Lead in and presentation T:And now let’s start from the beginning ,;Lesson1:A puma at large，This lesson is about an escaping puma, 這課講的是一頭正在逃遁的美洲獅，first，listen to me read the text carefully，and see if you can answer this question:where must the puma have come from? T:Pumas are large, ‘cat-like animals’ which are found in America.When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London, they were not taken seriously.However, as the evidence began to accumulate, experts from the Zoo felt obliged to investigate, for the descriptions given by people who claimed to have seen the puma were extraordinarily similar.The hunt for the puma began in a small village where a woman picking blackberries saw a large cat only five yards away from her.It immediately ran away when she saw it, and experts confirmed that a puma will not attack a human being unless it is cornered.The search proved difficult, for the puma was often observed at one place in the morning and at another place twenty miles away in the evening.Wherever it went, it left behind it a trail of dead deer and small animals like rabbits.Paw prints were seen in a number of places and puma fur was found clinging to bushes.Several people complained of ‘cat-like noises’ at night and a businessman on a fishing trip saw the puma up a tree.The experts were now fully convinced that the animal was a puma, but where had it come from ? As no pumas had been reported missing from any zoo in the country, this one must have been in the possession of a private collector and somehow managed to escape.The hunt went on for several weeks, but the puma was not caught.It is disturbing to think that a dangerous wild animal is still at large in the quiet countryside.T:So where must the puma have come from?注意這里用的是must have come from ,must 它的基本詞義是必須，但是它在這里表達的是一種 推斷和猜測,我們再回到這個問題，where must the puma have come from？the text tells us that the puma must have escaped from the private collection,也就是說這頭美洲獅是一個私人豢養的，這個結論呢是在有呢很多線索之后得到的，整篇課文給我們講述的是越來越充實的證據（accumulating evidence），講述的是專家們由不太當真(not taken seriously)到不得不去調查（felt obliged to investigate），到最后完全肯定的一個過程（fully convinced），那么這些證據究竟有哪些？又是怎樣影響了專家們的看法，請同學們在學習中理清課文的這些脈絡。T:Now let’s look at some language points in the text T:A puma at large

T:Be at large(潛逃),Who can give me an example of this expression? S:有學生舉手，多叫幾名同學，然后老師也可以給一個： The escaped prisoners are still at large（逃犯還沒有落網）T:這篇課文在幾處都出現了表示看或看見的詞語，When reports came into London Zoo that a wild puma had been spotted forty-five miles south of London……

People who claimed to have seen the puma…… The puma was often observed at one place……

T:表示看見這個意思，see是最常用的詞，而 observe要比see更加書面化，spot means to notice something very difficult to see ,or find something being looked for 表示看到了不太容易看到的東西，或者發現了正在尋找的東西。Who can give me an example? S:請學生回答；老師給出例子

I spotted someone coming out of the building

T:as the evidence began to accumulate, experts from the Zoo felt obliged to investigate……Accumulate means to gradually increase over a period of time 指的是逐漸增加或積累

T:feel obliged to 這是一個固定詞組，經常用來做書面語，同must，have to，have a duty to do 必須有義務、責任做……事 S:請學生回答并給出例子eg：I felt obliged to invite him

T:The hunt for the puma began in a small village where a woman picking blackberries saw a large cat;Hunt 捕獵 搜尋

T:請同學翻譯go on a deer /fox hunt 獵（鹿、狐）；The hunt for the remains of the titanic（搜尋TITANIC殘骸）；Hunt for second-hand book（搜尋二手書）；Job-hunting（找工作）T:Pick采摘；Pick cotton摘棉花；

S:請學生翻譯We need to pick someone reliable 挑選我們要找一個可靠的人，Pick and choose 挑挑揀揀

T:A puma will not attack a human being unless it is cornered;Cornered 陷入困境 被逼得走投無路

T:The search proved difficult;Prove=turn out to be 證明是 原來是VI S:請學生翻譯They proved her innocence

他們證實了她是無辜的（證實VT）；The rumor proved false 謠言證明是錯誤的；

T:Puma fur was found clinging to bushes ；Cling to 粘住 Cling-clung-clung 過去式過去分詞;

S:學生翻譯His wet shirt clung to his body ；She clings to the belief that her Husband will come back 她固執的相信她的丈夫會回來

T:Some people complained of ‘cat like noises’ at night ……表示報告或者是述說,表示一種不滿的情緒

T:complain跟的介詞不同意思也不同complain about the weather 抱怨天氣不好;complain of a headache 述說自己頭疼

T:It is disturbing to think that a dangerous wild animal is still at large in the quiet countryside，disturbing在這里等同worrying令人擔憂的不安的Disturb 打攪 Sorry to disturb you 對不起打擾你了;Do not disturb，請勿打擾！，His strange behavior disturbed me 他舉止反常讓我很擔心

T:However, as the evidence began to accumulate, experts from the Zoo felt obliged to investigate, for the descriptions given by people who claimed to have seen the puma were extraordinarily similar.T:大家都知道 在英文中基本的句型就是簡單句 并列句以及復雜句，就是我們經常聽到的simple sentences compound sentences complex sentences,這篇課文主要是由復雜句構成的，now look at sentence please ,要理解一個復雜句，最重要的是要搞清句子的結構，然后通過連接詞，分清主句和從句之間的關系，就是說要把握主句和從句的位置，而主句和從句的關系是由連接詞來判斷的，在這個句子當中，主句就是experts from the Zoo felt obliged to investigate，主句前邊有一個 as引導的從句，他表示的是一種伴隨主句同時發生的狀態，它的后邊又有一個for引導的從句來交代原因，而這個從句當中有一個given，它起的實際上是一個定語從句的作用，用來修飾 descriptions，如果用從句來表達就是which had been given by people，而這個從句當中由套著一個從句，是由who來引導的，用來修飾people，所以一個句子結構不論有多么復雜，只要我們能把握連接詞，在句子當中的作用，和意思，就不難理解。

T:When reports came into London Zoo that a wild puma had been spotted;the puma was often observed at one place in the morning and at another place;Paw prints were seen…… puma fur was found clinging to bushes;As no pumas had been reported missing from any zoo in the country

T:當英文中表示一個事實的客觀性的時候往往更多的使用被動語態，這篇課文就是這樣，講的是美洲獅在各處出現并且被人目擊的情形，我們來看看被動語態在課文當中的使用：had been spotted，was …… observed，were seen……，was found clinging，had been reported missing這都是被動語態最基本的構成;另外was found clinging

had been reported missing 是在被動語態之后加上現在分詞，起補充說明主語的作用

T：right,That’s about the language point,我們知道了西方有收集動物的人，在我們中國現在也有喂養寵物的人…… Step 3 Consolidation and homework T: Today we learned some new words and expressions , Who are they? Homework: 1.listen to the tape of lesson one 2.Read the text and recite to your parents and me.T:class is over,see you in the next lesson!.
