教學建議

課文分析

結構：可分為四段：

Part 1 ( Paragraph I ) The number of milu deer in nature parks in China is increasing every year.

Part 2 (Paragraphs 2-3) The history of milu deer in China and in England

　　　(Paragraph 2) The milu deer disappeared during the Ming and the Qing periods.

　　　(Paragraph 3) The only milu deer alive belonged to the Duke of Bedford in England.

Part 3 (Paragraphs 4-5) The milu deer centers in China

　　　(Paragraph 4) The life of milu is being studied in the Naniaizi Milu Park.

　　　(Paragraph 5) The number of milu deer has greatly increased in Dafeng.

Part 4 ( Paragraph 6) It's hoped that there will be milu deer living in the wild in China.

語言點：本課文有兩個要點，值得注意：

　　1．It’s hoped….that (人們希望)是個常用句型，其中的it是形式主語，that引導的是個主語從句。類似的有It is said /reported/believed/ that…..等

　　2．There are so many deer that some are being sent to nature reserves by environmentalists who would like to return them to the wild.其實，現在這種麋鹿已經相當多了，有一些正在被送往那些愿意把麋鹿送回野外去的地方。

　　1）該句是一個較為復雜的復合句，主句為…there are so many deer, that引導的是結果狀語從句。

　　在這個so……that結構中，中心詞是名詞deer，本應該用such…that結構，但因名詞前有many修飾而用了so……that結構，此特殊用法需注意。

　　are being sent是現在進行時的被動語態形式，表示“正在被送往”。

對話建議

1．建議在未講課前，教師為了導入新課，可對學生進行以下的提問：

　　T: Is there anyone collect money? S: Yes.

　　T: What did you do? Did you collect money for Hope Project or other things?等等。

2．在講本文對話時，教師給學生放課文錄音，然后問學生們What’s the dialogue mainly about? 。

3．建議教師讓學生們扮演角色，通過互相表演的形式，促進學生的興趣，及練習表達能力。

4．教師總結本課的語言點知識。

課文建議

1．建議教師把有關本課文有關the milu deer的背景知識介紹給學生，使學生先有一些了解和認識。

2．在未講課之前，讓學生大聲的對這篇課文進行朗讀，教師可把課文的一些問題寫在黑板上，達到一邊朗讀一邊思考問題。

3．教師結合課文的內容，可有圖表或者數據形式，對the milu deer 用過去，現在及將來三種形式分析給學生，這樣加深對課文的理解和生動。

4．教師最后總結課文的知識點，了解學生的掌握情況。

語法建議

1．建議教師把在講現在進行時的被動語態前，先復習現在進行時。

2．教師可采取逐步誘導的形式，從定義，構成，及應注意的用法，用圖片或投影儀形式，教給學生。

2．建議教師列舉例題及練習試題，讓學生一邊做一邊練，達到掌握熟練的結果。

詞匯辨析

common, general, ordinary和usual

可作“普通的”“平常的”但有所差異。

common側重“普通”，表示“時時發生，人所共有”，并含有“并不高貴，地位低下”之意味，其反義詞為rare。

general側重“普遍”之意，表示在大多數我或事物中流行并受到關注，不含有“地位低下”之意，其反義詞為specific。

ordinary與common基本同義，側重“平凡的，普通的”，表示“隨時可以碰到，不值得驚奇”，其反義詞是superior。

usual用來指事物，意為“通常的，慣常的”，含有“隨集體風俗或個人習慣而常常發生”之意，其反義詞為unusual。舉例如下：

a common saying（俗話），a common wish（一個共同的愿望）。

the general opinion一般輿論

an ordinary（or a common）event（一件極平常的事），an ordinary（or a common）person（一個普通人）。

It’s a usual thing with him. （這對他來說是平常事）。

The number of 和A number of

A number of意為“許多、”“一些”，后接復數的可數名詞。有a large/ great/small number of等詞組。a number of + n. (復)作主語時，謂語動詞要用復數。這兩個詞組后都接可數名詞復數，但a number of的中心是后面的復數名詞，作主語時，謂語用復數形式。

the number of意為“……的數目”，它的中心是the number，后也接復數的可數名詞，作主語時，謂語動詞要用單數。舉例如下：

①I can think of a number of ways to carry out this plan. 我可以想出不止一個辦法來實現這個方案。

②A large number of people were present at the meeting. 有許多人出席了會議。

③A number of students are staying outside the office. 許多學生站在辦公室的外面。

①The number of the students standing outside is about twenty. 站在外面的學生數量大約是加入。

②The number of the books in our library is about 45,000.我們圖書館藏書量大約為4萬5千冊。

year by year 與year after year

year by year即“逐年，每一年”，強調“年年在變”，

The boy grows taller year by year這個孩子長得一年比一年高。

year after year意含時間的重復性，即“每年固定發生，年年如此”。

He went to Beijing on business year after year.他每年到北京當差。

例The number of computers is increasing _____, which has brought the price down.

A. year by year B. year after year C. years after years D. years by years

解析：句意為：電腦數量逐年增長，使得價格下降。本題考查year by year 與year after year的區別。year by year 意為“年年在變”；year after year意為“年年如此”。由句意可知答案為A。

research與search

相同點：兩詞均有研究、探索之意。

research指審慎的或精密的探究，有科學的研究或批判的研究之意。一般批學問、宗教、物理、心理、天文等方面調查或研究，常用復數。

search則有搜索、探索之意、側重對某事持續的調查或研究，用于搜索或尋找失竊物品或探究知識、真理、自由、珍禽、奇術等方面。舉例如下：

They are researching on the effects of cigarette smoking. 他們正在研究吸煙的后果。

He went all over the world to search after truth. 為追求真理他行遍全球。

travel, journey, trip, tour, voyage

相同點：這五個詞都作“旅行”解。

Travel：可作動詞或名詞，指遠距離長期的旅行，沒有具體的目的和方向性。常用來表示“旅行”這一概念。名詞的復數形式travels表示旅行經歷。

journey：使用范圍很廣，但常指距離較遠的陸路旅行，而且有預定的地點，帶有明確的方向性。

Trip：常指距離短且直接到達目的地的旅行。在口語中trip與journey常常通用。

Tour：含有“觀光”的意思，距離可長可短�？勺鲃釉~或名詞。

Voyage：指“航行，航�！敝杆坊蚝娇章眯�。舉例如下：

He has travelled all over Africa many times in his life. 他一生中多次到非洲旅行。

Marco Polo wrote a book about his travels in China，which is called The Travels of Marco Polo.

馬可波羅把他在中國的旅行寫成了一本書，書名叫《馬可波羅游記》。

Mr. Black is on his journey to Shanghai.布萊克先生正在去上海的旅途中。

We are planning to make a trip to the Great. Wall.我們正計劃去長城游覽。

I'm going on a shopping tour. Would you like to go with me? 我想去逛商店，你想不想跟我一起去？

They're making a voyage to Africa. 他們正在作一次去非洲的航海旅行。

難句分析

In fact, there are so many deer that some are being sent to nature reserves by environmentalists who would like to return them to the wild.其實，現在這種麋鹿已經相當多了，有一些正在被送往那些愿意把麋鹿送回野外去的地方。

1）該句是一個較為復雜的復合句，主句為…there are so many deer, that引導的是結果狀語從句。

在這個so……that結構中，中心詞是名詞deer，本應該用such…that結構，但因名詞前有many修飾而用了so……that結構，此特殊用法需注意。

2）are being sent是現在進行時的被動語態形式，表示“正在被送往”，其中的being容易被誤省。又如本課中的其他兩句：

More milu deer are being moved to a new large nature park in Shishou in Hubei Province.

現在進行時的被動語態

定義：

現在進行時的被動語態表示此時此刻某事正在被做。例如：

　　The sports meeting is being held in our school. 我校正在舉行運動會。

　　Another bridge is being built over the Changjiang River. 長江上正在修建另一座大橋。

構成：be + being+過去分詞。例如：

　　A number of Dongfeng trucks are being shipped abroad.一批東風卡車正被運往國外。

用法：

　　1）“be being done” 中的動詞be應隨主語(sing. / pl.)作相應的變化。

　　2）將現在進行時的主動語態變為現在進行時的被動語態的關鍵是：把be doing變為be being done.

　�、賂he students are cleaning the classroom now.→The classroom is being cleaned now.

　　現在學生們正在打掃教室。 (are cleaning變為is being cleaned)

　�、赥he boy is counting some eggs.→Some eggs are being counted.

　　那男孩正在數蛋。 (is counting 變為 are being counted)

例題：

—Have you moved into the new house? —Not yet, the rooms ______.

　　A. are being painted B. are painting

　　C. are painted D. are being painting

　　【解析】該題house作主語與備選項提供的動詞paint之間存在著被動關系。用現在進行時的被動語態，說明還沒搬進新居的原因是“房子正在被粉刷”。故答案為A項。

練習：

1.Look! The roads ____now.

　　A. are widening　　B. are widened

　　C. are being widened D. is to widen

2.A science lab ____in our school now.

　　A.is being built　　B. has built

　　C. is building 　　D. will be built

答案：1.C 2.A
