教學建議一
教材內(nèi)容分析
本單元的中心問題是當代人們最關(guān)注的問題之 — 人口問題。課文“Standing room only”介紹了世界人口迅速增長的狀況，所帶來的一系列問題，如糧食緊缺、就業(yè)困難、住房緊張等，說明控制人口增長的重要性和必要性，以雄辯的事實對同學們進行人口教育，使他們進一步認識到中國實行計劃生育政策的必要性和深遠意義。本單元學習了數(shù)詞的表示法和讀法，過去將來時態(tài)的構(gòu)成和基本用法，詢問人口的句型。英語中就人口提問只用what，不用 how many或 how much。本單元還學習了，常用詞語和表示位置移動的動詞可用過去進行時表示過去將來時態(tài)。
本單元重點例句及相關(guān)知識講解
1. 3，333，333，333三十三億三千三百三十三萬三千三百三十三。
讀寫多位數(shù)時要注意以下幾點：
�。�1）1，000以上的數(shù)字，要用計數(shù)退點“，”。從個位開始，每隔三位加一個逗點。第一個逗點前是thousand，第二個逗點前是million．第三個逗點前是billion（美國英語說法）或thousand million（英國英語說法）。
�。�2）分段之后，每段都成了l～999之間的數(shù)了，讀寫時在十位（個位）數(shù)與百位數(shù)之間加and。
�。�3）英語中無單獨表示“萬”和“億”的量詞，故用ten thousand表示“一萬”，one hundred thousand 表示“十萬”，twenty million表示“二千萬”，three hundred million表示“三億”。
因此，上面的數(shù)字就讀成：three billion three hundred and thirty－three million three hundred and thirty-three thousand three hundred and thirty-three。
2．What’s the population of Germany? 德國的人口是多少？
population是個集合名詞，意思是“人口；人數(shù)”，常用來指人口的總稱，在日常使用時，必須注意以下幾種用法：
�。�1）population是一個集合名詞，在句中作主語時，謂語動詞多用單數(shù)形式。如：
The population of Germany is about 81,000,000. 德國大約有八千一百萬人口。
The world's population is growing faster and faster. 世界人口增長越來越快。
注：如果population與分數(shù)或百分數(shù)連用時，謂語動詞多用復數(shù)形式。如：
Three fifths of the population in our town are farmers. 我們鎮(zhèn)五分之三的人是農(nóng)民。
�。�2）表示“……的人口”可用the population of +地名，也可用the population in +地名，作主語中心詞時，謂語動詞用單數(shù)形式。如：
The population of Canada is 28,100,000. 加拿大人口是二千八百一十萬。
（3）表示某國、某城市有多少人口時，還可用… have/has a population of…結(jié)構(gòu)。如：
The city has a population of 50,000. 那座城市有五萬人。
注：people常用于表示具體的人數(shù)，雖然people不加"s"，但謂語動詞常用復數(shù)。如：
How many people are there in your family? 你家有幾口人？
（4）由于population是不可數(shù)名詞，因此不用How many也不用How much進行提問，應用What / How large。如：
1）What's the population of China? 中國有多少人口？
2）澳大利亞有多少人？
誤：How many is the population of Australia?
正：How large is the population of Australia?
�。�5）說明人口或人數(shù)的“多”或“少”時，不用many/few/much/little修飾，而用large, big或small, thin修飾。如：
Dalian has a large population. 大連人口很多。Which country has the smallest population Canada, the USA or Australia? 加拿大、美國、澳大利亞哪個國家的人口最少？
3. I wonder if that’s a lot of people for the size of the country. 我想知道這個國家能否容的下這么多人。
句中wonder的意思是want to know，常接if或whether引導的賓語從句。如：
I wonder if it is true. 我想知道這是不是真的。
I wonder whether Tom will come. 我不曉得湯姆來不來。
句中size 是名詞，意思是“容量；尺寸；大��；面積”。如：
It was about the size of a duck’s egg. 其大小約如鴨蛋。
His shoes are Size 10. 他的鞋是十碼的。
The earth is 49 times the size of the moon. 地球大約是月球的49倍。
4. Multiply this by 365. 用365來乘它（370，000）
（1）multiply A by B 用B乘A。
例：6 multiplied by 5 is 30. (6×5=30)6乘5等于30。
（2）“乘”的另外一種表達法是times�！俺痹�英語中用divide表示。
例：6 times 5 is (are) 30. 30 divided by 5 is 6.
(6×5=30) 6乘5等于30。(30 ÷ 5=6) 30除以等于6。
�。�3）句中by是介詞，意思是“相差”指程度。如：
He is taller than I by a head. 他比我高一個頭。
“……+by+數(shù)字或倍數(shù)+……”在本句型中有比較級出現(xiàn)或有表示增減意義的動詞或分詞出現(xiàn)時，by后表示的都是凈增減的數(shù)或增加的倍數(shù)。如：
A is by 2 inches longer than B. A比B長二吋。
300 increased by 200 is 500. 300加200等于500。
900 decreased by 100 is 800. 900減100等于800。
注意如果句中用go up（上升）代替increase時，就不能用by。
5．The world’s population is growing faster and faster．世界人口增長得越來越快。
the world’s population還可以說成：the population of the world／the world population這三種說法都譯為“世界人口”，只是表達形式不同。第一種說法是名詞所有格作定語；第二種說法是“of屬格”作定語；第三種說法是名詞作定語。注意，如說“中國人口”，應說：the population of China或the China’s population。但不能用表示“某國”的形容詞作定語，即不能說the Chinese population，因為形容詞Chinese（中國的）French（法國的）German（德國的）等不表示所屬關(guān)系。
形容詞或副詞的比較級連用表示“越來越……”，例如：
English is becoming more and more important．She studies English harder and harder．Her score is becoming better and better．英語變得越來越重要。她學習英語越來越用功。她的成績越來越好
6．People say that by the year 2010, it may be seven billion.
人們認為到2010年，人口將達70億。
�。�1） 句中by the year 2010是“到2010年”的意思。相關(guān) by的短語有：by the end of…到……末為止，只用來表示時間，常與完成時態(tài)連用，也可用于將來時態(tài)。與之相關(guān)的短語有：
at the end of在……末，在……末端（盡頭），可以表示時間，也可表示地點，常與過去時態(tài)或?qū)頃r態(tài)連用。
to the end到（某一）終點為止，可表示時間，也可表示地點，指時間常用till代替to。
in the end最終、終于，相當于at last或 finally。
【例】1）We had learned eleven English songs by the end of last term．We had an English songs exam at the end of last month．He stayed there till(to) the end of last month．
到上學期末，我們已學了十一首英語歌曲。上月末我們進行了一場英語歌考試。他在那兒一直呆到上月月底。
2）You can find the post office at the end of this street．Go down that street to the end and you will find the hospital．
在這條街的盡頭，你會找到郵局的。沿著那條街走到底，你會找到那所醫(yī)院的。
�。�2）by還可表達下列意思：
by在……旁邊
The writer often saw an old man fish by the lake. 作者經(jīng)�？匆娨晃焕险咴诤呩烎~。
by使用……工具
Miss Smith goes to work by car but she is sometimes late. Smith小姐開車上班但有時她還是遲到。
by：由……，被……，表示被動關(guān)系。
This book was written by my father in 1998.這本書是由我父親在于1998年寫的。
by the end of…到……底為止，它不是指在某個時間點，而是指某一點時間之前或到某一點時間為止是一種什么情況。強調(diào)的是狀態(tài)或結(jié)果。其后接表示時間的名詞并與之構(gòu)成時間狀語。如：
He will be 16 years old by the end of next month. 他到下個月底就16歲了。
7．That means that in about 600 years, there will be standing room only on the earth．這意味著大約600年后，地球上將只有立足之地。
（1）副詞only一般放在它所修飾的詞或短語之前。否則，就會引起句意的不同。
例：Only Tom drives the new car on Sunday．只有Tom在周日開新車。
Tom only drives the new car on Sunday．周日Tom只開開新車，而不做別的事。
Tom drives only the new car on Sunday．Tom在周日只開新的車子。
Tom drives the new car only Sunday．Tom只有在周日才開新車。
�。�2）standing在這里是動名詞，“站的地方；立足之地”。作room的定語，整個短語相當于room for standing only. -ing形式修飾名詞表示用途的情況還有：
waiting room 候車室
walking stick 拐棍，手杖
fishing pole 釣魚竿
�。�3）此處的room表示“空間”，是個不可數(shù)名詞，相當于space。常用于“There be句型”和“make room for sb．”，“take up much／little room”等短語中。
例：This table takes up too much room of his bedroom．
這張桌子占了他臥室里太多的空間（地方）。
本句中有兩個that，但作用意思完全不同。前者為指示代詞，指代上文中所講人口增長的嚴峻形勢，作主語，意為“這種情況”；后者為連詞，引導means后的賓語從句，無詞義。
�。�4）in／after／later這三個詞均可表示“在……之后”的意思，其用法及區(qū)別是：
in作為介詞，后跟一段時間，表示從現(xiàn)在算起的“一段時間之后”，常用于一般將來時態(tài)。例如：
l）I’ll come back in a minute．我一會兒就回來。
2）What will happen in a hundred years？100年后會發(fā)生什么事呢？
after也是介詞，表示從過去某時起的若干時間之后，謂語動詞用過去時，不可用于將來時。但是，在表示某一具體時間或某一具體事件之后，則用在將來時或過去時中。例如：
1）He came back after two years．他兩年后回來了。
2）After three days Wang Hai found his bike．三天后王海找到了他的自行車。
3）After the meeting, we’ll discuss it．會議后，我們將討論這件事。
4）We will get there after two o’clock．兩點鐘后，我們將到那里。
later是副詞，在句中作狀語，既能以過去某個時間為基準，也能以現(xiàn)在為基準，因此可用于一般過去時態(tài)或一般將來時態(tài)。例如：
1）Later, he was interested in science．后來，他對自然科學發(fā)生了興趣。
2）The radio says the sun will come out later．廣播說太陽過一會兒就會出來。
注意：“一段時間 + later”是副詞詞組，表示“若干時間以后”，有兩種用法：
① 用于過去時態(tài)，表示“從過去某一時間算起，過若干時間后”，與“after+段時間”意思相同。例如：Half an hour later she woke up and began to cry．半個小時后她醒了，開始哭起來。
② 用于將來時態(tài)，表示“從將來的某一時間算起，過若干時間后”。例如：He will go there on May 1, and will go there again a few days later．五月一日他將到那兒，幾天后他還要再去那兒。
8．I don't agree with you two．我不同意你們兩人（的觀點）。
句中agree是“同意；取得一致意見”的意思。agree作及物動詞用時，后面通常跟名詞、不定式或that引起的從句作賓語。其可以單獨使用，也可以和介詞to，with，on等連用，agree on常用在被動結(jié)構(gòu)中，以事物作主語時，表示“（某事）是大家都同意的”意思，有時on也可以省略。
【例】
（1）Can we agree the price 我們能不能商定一個價格？
�。�2）I agree that your suggestion is quite good．
我認為你的建議非常好。
（3）I really can't agree with you．
我實在不能同意你的意見。
（4）We agreed on the date for the meeting．
我們對開會的日期取得了一致的意見。
�。�5）After a short time, the program was agreed (on)．
過了一會兒，這項計劃大家都同意了。
（6）He has agreed to our plan for the holiday．
他已經(jīng)同意我們的假期計劃。
9. prefer v. 寧愿，更喜歡
1）跟名詞或代詞。例如：
Southerners prefer rice and northerners foods made from flour．
南方人比較愛吃米飯，北方人比較愛吃面食。
They prefer new works that sing of their life today. I prefer the view taken by Xiao Yang who like the old songs．This construction is much to be preferred.
他們更喜歡歌頌他們今天生活的新作品。我傾向于小楊的喜歡老歌的意見。這種結(jié)構(gòu)更好一些。
2）跟不定式。例如：
I prefer to walk there．我寧愿走路去。
But people prefer to order their dishes if they have the time．
但人們更愿意點菜，如果有時間的話。
At the moment they preferred not to talk about this question．
在這個時刻，他寧愿不談這個問題。
We should have preferred to leave on the 8th, but we didn’t because we had to wait for another classmate．
我們本來更愿意在八號走的，但沒有成功，因為我們得等另外一個同學。
3）跟V+ ing結(jié)構(gòu)。例如：

她更愿意我們一聽完課就討論。
I would have preferred that we do it some other way．
我倒愿意我們采取另一種做法。
教學建議二
過去將來時態(tài)
一、過去將來時的構(gòu)成：
would+動詞原形或was/ were going to+動詞原形
如：The farmers didn’t know whether they would have a good harvest.農(nóng)民們不知道他們是否會有一個好收成。
Li Mei said that she was going to visit her grandma in the country the next Sunday.李梅說下星期天要去看望她鄉(xiāng)下的祖母。
二、過去將來時的用法：
過去將來時表示從過去某個時間看將來要看發(fā)生的動作或存在的狀態(tài)。具體分為：
1．主句為過去時，賓語從句常表示將要發(fā)生的事情。如：
Nobody knew what would happen after a hundred years. 沒有人知道一百年之后將會發(fā)生什么事。
We didn’t know whether she was going to speak at the meeting. 我們不知道她是否準備在會上發(fā)言。
2．在敘述過去的事情或事情發(fā)生的經(jīng)過時，用過去將來時表示在當時看將來會發(fā)生的事。如：
It was a Saturday afternoon. A young man named George had just left school. He was going to start to work the following week, so he decided to buy some new clothes and a new pair of shoes.一個星期六的下午，一位名叫喬治的年輕人剛離開學校。因為他準備下周開始工作，所以，決定買些新衣服和一雙新鞋子。
3．過去將來時態(tài)一般不能單獨使用。因為它表示過去和將來雙重的時態(tài)概念，必須有另一個時態(tài)作為比較或襯托。但在一定的上下文中，也可單獨使用。例如：
That afternoon I was on my way home after three years of absence. My whole family would all come out to welcome me back, and I should see my aged and long-de-parted parents very soon．
那天下午，我在離別三年之后踏上了回家的路。我的全家都會出來迎接我，不久我即將見到我那分別已久的年邁父母。
三、過去將來時的其他表示法
1．在時間或條件狀語從句中，常用一般過去時表示在過去看將來要發(fā)生的動作。如：
They said that they were going to West Hill Farm if it didn’t rain the next Sunday. 他們說如果下星期天不下雨他們就去西山農(nóng)場。
The teacher asked Tom what he was going to be when he grew up. 老師問湯姆長大后準備干什么。
2．go, come, leave, fly, drive, arrive, start等表示位置移動的動詞常用過去進行時表示一個當時按計劃或安排近期將要發(fā)生的動作。如：
She didn’t say when she was coming again next time. 她沒說下一次什么時候會再來。
Jim decided they were flying to England next month. 吉姆決定他們下個月坐飛機去英國。
數(shù)詞的表達法
1—20逐個熟記。
21~99：先說“幾十”，再說“幾”，中間加連字號。如：35—thirty-five 69—sixty-nine 。
101~999：先說“幾百”，再加and，再加末尾兩位數(shù)或一位數(shù)。如：
226—two hundred and twenty-six
518—five hundred and eighteen
905—nine hundred and five
4位和4位以上的數(shù)字：先從后向前數(shù)，每三位數(shù)空半個阿拉伯數(shù)字的位置，第一個空前為thousand（千），第二個空前為million（百萬），第三個空前為billion（十億，美式）或thousand million（英式），然后一節(jié)一節(jié)讀出。（或每三位為一段，用逗號分開，第一個逗號前是thousand，第二個逗號前是million，第三個逗號前是billion。）如：
2 002—two thousand and two
6 000—six thousand
9 876—nine thousand，eight hundred and seventy-six
198 407—a（one）hundred and ninety-eight thousand，four hundred and seven
18 657 421—eighteen million，six hundred and fifty-seven thousand，four hundred and twenty-one
8 000 000 000—eight billion（美式）或eight thousand million（英式），如：
1 000 000 000 000—a（one）trillion（美式），a（one）billion（英式）
注意在上述這樣數(shù)詞中，hundred，thousand，million等詞一般用單數(shù)形式。如：
ten thousand 一萬
a hundred thousand 十萬
a hundred million 一億
a thousand million 十億
a billion 十億
注意：英語沒有單獨表示“萬”和“億”的單詞。表示“一萬”要用ten thousand，表示“一千萬”要用ten million，表示“一億”要用a hundred million。
教學建議三
過去將來時的教學建議
本單元的語法重點是過去將來時。過去將來時是表示對過去某一時間來說將要發(fā)生的動作或狀況。通常用would或was/were going to+動詞原形來表示。如：He said he would go to his hometown for the Spring Festival. 他說他將回家鄉(xiāng)去過春節(jié)。
They told me that they would visit China the next week.他們告訴我他們下星期將訪問中國。
She said that she was going to do some shopping the next day. 她說她第二天將去買東西。
過去將來時通常在以下幾種情況下使用。
1．主句為過去時，在賓語從句中表示將來的事情用過去將來時。如第51課中第3部分
Make sentences中的句子：
I didn’t know that they would be able to buy another car.
My uncle never knew that a car would cost more than a house.
意思是：“我當時不知道他們會買另一輛新車�！� “我叔叔當時不知道一輛汽車會比一幢房子貴。”
2．在敘述過去的事情時，在當時看來將要發(fā)生的事。如：
She was our new teacher and she would be 30 years old that year. We all liked her very much and we were going to have a party for her birthday. 她那時是我們的新老師。她那一年就到30歲了。我們非常喜歡她，打算為她舉辦一次生日聚會。
過去將來時還有其他一些用法，教師不必講得太多，因為這個時態(tài)在初中階段僅要求理
解�？梢灾笇W生把一些句子改為過去將來時，如：
The small children did not know who filled their stockings.
The small children did not know who would fill their stockings.小孩子們不知道誰將往他們的襪子里塞東西。
They didn't know what would be in their stockings.小孩子們不知道誰將往他們的襪子里塞東西。
下面一組句子可供教師們作補充練習：
I didn't know that they would be all there. 我不知道他們都會去那兒。
They didn't know whether we would win or not. 他們不知道我們是否會取勝。
He told Jim not to worry. He would take care of Polly. 他告訴吉姆不必擔心，他會照看波利的。
He said he was going to send me a Christmas card. 他說他將會給我寄一張圣誕卡。
I couldn't decide which school I would go to. 我當時無法決定上哪一所學校。
數(shù)字讀法的教學建議
第49課重點訓練大數(shù)字的讀法，除了要向?qū)W生講清楚讀多位數(shù)字要注意的規(guī)則外，還要引導學生通過練習逐漸熟練地掌握，不要急于求成。本單元話題是世界人口問題，為訓練多位數(shù)字的讀法提供了真實、自然的語言情景。
第49課第一、二部分主要是教學多位數(shù)字的引入和練習階段，可用卡片或把數(shù)字寫在黑板上的方法教學。教師應引導學生總結(jié)讀數(shù)字的規(guī)律。
Number Chinese English
l0，000 一萬 ten thousand
100，000 十萬 hundred thousand
1，000，000 百萬 million
l0，000，000 千萬 ten million
l00，000，000 億 hundred million
l，000，000，000 十億 thousand million/billion
在處理第三部分Ask and answer時，可用世界地圖，從中國人口談起，如：This is China. How many people are there in China? 然后換句話問：What's the population of China? 鼓勵學生從上下文中猜測population的詞義。引導學生答出：About 1,200,000,000，接下來再問：Do you think it will grow? 等。這樣反復練習幾個國家后，再讓學生打開書分小組做替換練習。
關(guān)于閱讀課文的教學建議
第50課課文“只有立足之地”通過介紹世界人口迅速增長的狀況，說明控制人口增長的重要性和必然性�？梢栽谧寣W生打開書前，問一些有關(guān)問題，如：
The world's population is growing very fast. This is a big problem.
Can anyone tell me why? 引導學生認識到世界人口的迅速增長會帶來糧食缺少，就業(yè)困難和住房緊張等問題，并由此引出課文題目Standing room only。
在解釋課文題目時，可以讓學生打開書看課文插圖，或通過切身體會談人口多的弊病與生活空間狹小的麻煩。可以引導學生通過閱讀課文理解課文題目的含義，也可以先初步了解課文題目的意思預測課文中要談到的內(nèi)容。有意識地培養(yǎng)學生利用課文題目和課文插圖預測課文內(nèi)容的能力。在閱讀課文前，可以給學生一個快速查閱(scanning)的任務，例如讓他們在一分鐘內(nèi)，從課文中找出有關(guān)世界人口增長的一組數(shù)字。如：
the number of babies born in one minute
the number of babies born in one hour
the world's population two thousand years ago
the world's population in 1990
閱讀課文后，可以讓學生分組討論課文中提出的人口增長的問題，進一步認識到中國實行計劃生育(Family planning)政策的必要性和深遠意義。也可以做角色表演(Role play)，其中一人是《中學生報》記者，另一人是人口問題專家，小記者和專家可根據(jù)課文內(nèi)容就世界人口問題進行問答，然后互換角色。還可留作家庭作業(yè)進一步練習、鞏固。
