教学建议一

教材内容分析

  本单元的中心问题是当代人们最关注的问题之 — 人口问题。课文“Standing room only”介绍了世界人口迅速增长的状况,所带来的一系列问题,如粮食紧缺、就业困难、住房紧张等,说明控制人口增长的重要性和必要性,以雄辩的事实对同学们进行人口教育,使他们进一步认识到中国实行计划生育政策的必要性和深远意义。本单元学习了数词的表示法和读法,过去将来时态的构成和基本用法,询问人口的句型。英语中就人口提问只用what,不用 how many或 how much。本单元还学习了,常用词语和表示位置移动的动词可用过去进行时表示过去将来时态。

本单元重点例句及相关知识讲解

  1. 3,333,333,333三十三亿三千三百三十三万三千三百三十三。

   读写多位数时要注意以下几点:

  (1)1,000以上的数字,要用计数退点“,”。从个位开始,每隔三位加一个逗点。第一个逗点前是thousand,第二个逗点前是million.第三个逗点前是billion(美国英语说法)或thousand million(英国英语说法)。

  (2)分段之后,每段都成了l~999之间的数了,读写时在十位(个位)数与百位数之间加and。

  (3)英语中无单独表示“万”和“亿”的量词,故用ten thousand表示“一万”,one hundred thousand 表示“十万”,twenty million表示“二千万”,three hundred million表示“三亿”。

  因此,上面的数字就读成: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? 德国的人口是多少?

  population是个集合名词,意思是“人口;人数”,常用来指人口的总称,在日常使用时,必须注意以下几种用法:

  (1)population是一个集合名词,在句中作主语时,谓语动词多用单数形式。如:

  The population of Germany is about 81,000,000. 德国大约有八千一百万人口。

  The world's population is growing faster and faster. 世界人口增长越来越快。

  注:如果population与分数或百分数连用时,谓语动词多用复数形式。如:

  Three fifths of the population in our town are farmers. 我们镇五分之三的人是农民。

  (2)表示“……的人口”可用the population of +地名,也可用the population in +地名,作主语中心词时,谓语动词用单数形式。如:

  The population of Canada is 28,100,000. 加拿大人口是二千八百一十万。

  (3)表示某国、某城市有多少人口时,还可用… have/has a population of…结构。如:

  The city has a population of 50,000. 那座城市有五万人。

  注:people常用于表示具体的人数,虽然people不加"s",但谓语动词常用复数。如:

  How many people are there in your family? 你家有几口人?

  (4)由于population是不可数名词,因此不用How many也不用How much进行提问,应用What / How large。如:

  1)What's the population of China? 中国有多少人口?

  2)澳大利亚有多少人?

  误:How many is the population of Australia?

  正:How large is the population of Australia?

  (5)说明人口或人数的“多”或“少”时,不用many/few/much/little修饰,而用large, big或small, thin修饰。如:

  Dalian has a large population. 大连人口很多。Which country has the smallest population Canada, the USA or Australia? 加拿大、美国、澳大利亚哪个国家的人口最少?

  3. I wonder if that’s a lot of people for the size of the country. 我想知道这个国家能否容的下这么多人。

  句中wonder的意思是want to know,常接if或whether引导的宾语从句。如:

  I wonder if it is true. 我想知道这是不是真的。

  I wonder whether Tom will come. 我不晓得汤姆来不来。

  句中size 是名词,意思是“容量;尺寸;大小;面积”。如:

  It was about the size of a duck’s egg. 其大小约如鸭蛋。

  His shoes are Size 10. 他的鞋是十码的。

  The earth is 49 times the size of the moon. 地球大约是月球的49倍。

  4. Multiply this by 365. 用365来乘它(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”的另外一种表达法是times。“除”在英语中用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是介词,意思是“相差”指程度。如:

  He is taller than I by a head. 他比我高一个头。

  “……+by+数字或倍数+……”在本句型中有比较级出现或有表示增减意义的动词或分词出现时,by后表示的都是净增减的数或增加的倍数。如:

  A is by 2 inches longer than B. A比B长二吋。

  300 increased by 200 is 500. 300加200等于500。

  900 decreased by 100 is 800. 900减100等于800。

  注意如果句中用go up(上升)代替increase时,就不能用by。

  5.The world’s population is growing faster and faster.世界人口增长得越来越快。

  the world’s population还可以说成:the population of the world/the world population这三种说法都译为“世界人口”,只是表达形式不同。第一种说法是名词所有格作定语;第二种说法是“of属格”作定语;第三种说法是名词作定语。注意,如说“中国人口”,应说:the population of China或the China’s population。但不能用表示“某国”的形容词作定语,即不能说the Chinese population,因为形容词Chinese(中国的)French(法国的)German(德国的)等不表示所属关系。

  形容词或副词的比较级连用表示“越来越……”,例如:

  English is becoming more and more important.She studies English harder and harder.Her score is becoming better and better.英语变得越来越重要。她学习英语越来越用功。她的成绩越来越好

  6.People say that by the year 2010, it may be seven billion.

  人们认为到2010年,人口将达70亿。

  (1) 句中by the year 2010是“到2010年”的意思。相关 by的短语有:by the end of…到……末为止,只用来表示时间,常与完成时态连用,也可用于将来时态。与之相关的短语有:

  at the end of在……末,在……末端(尽头),可以表示时间,也可表示地点,常与过去时态或将来时态连用。

  to the end到(某一)终点为止,可表示时间,也可表示地点,指时间常用till代替to。

  in the end最终、终于,相当于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.

  到上学期末,我们已学了十一首英语歌曲。上月末我们进行了一场英语歌考试。他在那儿一直呆到上月月底。

  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.

  在这条街的尽头,你会找到邮局的。沿着那条街走到底,你会找到那所医院的。

  (2)by还可表达下列意思:

  by在……旁边

  The writer often saw an old man fish by the lake. 作者经常看见一位老者在湖边钓鱼。

  by使用……工具

  Miss Smith goes to work by car but she is sometimes late. Smith小姐开车上班但有时她还是迟到。

  by:由……,被……,表示被动关系。

  This book was written by my father in 1998.这本书是由我父亲在于1998年写的。

  by the end of…到……底为止,它不是指在某个时间点,而是指某一点时间之前或到某一点时间为止是一种什么情况。强调的是状态或结果。其后接表示时间的名词并与之构成时间状语。如:

  He will be 16 years old by the end of next month. 他到下个月底就16岁了。

  7.That means that in about 600 years, there will be standing room only on the earth.这意味着大约600年后,地球上将只有立足之地。

  (1)副词only一般放在它所修饰的词或短语之前。否则,就会引起句意的`不同。

  例:Only Tom drives the new car on Sunday.只有Tom在周日开新车。

  Tom only drives the new car on Sunday.周日Tom只开开新车,而不做别的事。

  Tom drives only the new car on Sunday.Tom在周日只开新的车子。

  Tom drives the new car only Sunday.Tom只有在周日才开新车。

  (2)standing在这里是动名词,“站的地方;立足之地”。作room的定语,整个短语相当于room for standing only. -ing形式修饰名词表示用途的情况还有:

  waiting room 候车室

  walking stick 拐棍,手杖

  fishing pole 钓鱼竿

  (3)此处的room表示“空间”,是个不可数名词,相当于space。常用于“There be句型”和“make room for sb.”,“take up much/little room”等短语中。

  例:This table takes up too much room of his bedroom.

  这张桌子占了他卧室里太多的空间(地方)。

  本句中有两个that,但作用意思完全不同。前者为指示代词,指代上文中所讲人口增长的严峻形势,作主语,意为“这种情况”;后者为连词,引导means后的宾语从句,无词义。

  (4)in/after/later这三个词均可表示“在……之后”的意思,其用法及区别是:

  in作为介词,后跟一段时间,表示从现在算起的“一段时间之后”,常用于一般将来时态。例如:

  l)I’ll come back in a minute.我一会儿就回来。

  2)What will happen in a hundred years?100年后会发生什么事呢?

  after也是介词,表示从过去某时起的若干时间之后,谓语动词用过去时,不可用于将来时。但是,在表示某一具体时间或某一具体事件之后,则用在将来时或过去时中。例如:

  1)He came back after two years.他两年后回来了。

  2)After three days Wang Hai found his bike.三天后王海找到了他的自行车。

  3)After the meeting, we’ll discuss it.会议后,我们将讨论这件事。

  4)We will get there after two o’clock.两点钟后,我们将到那里。

  later是副词,在句中作状语,既能以过去某个时间为基准,也能以现在为基准,因此可用于一般过去时态或一般将来时态。例如:

  1)Later, he was interested in science.后来,他对自然科学发生了兴趣。

  2)The radio says the sun will come out later.广播说太阳过一会儿就会出来。

  注意:“一段时间 + later”是副词词组,表示“若干时间以后”,有两种用法:

  ① 用于过去时态,表示“从过去某一时间算起,过若干时间后”,与“after+段时间”意思相同。例如:Half an hour later she woke up and began to cry.半个小时后她醒了,开始哭起来。

  ② 用于将来时态,表示“从将来的某一时间算起,过若干时间后”。例如:He will go there on May 1, and will go there again a few days later.五月一日他将到那儿,几天后他还要再去那儿。

  8.I don't agree with you two.我不同意你们两人(的观点)。

  句中agree是“同意;取得一致意见”的意思。agree作及物动词用时,后面通常跟名词、不定式或that引起的从句作宾语。其可以单独使用,也可以和介词to,with,on等连用,agree on常用在被动结构中,以事物作主语时,表示“(某事)是大家都同意的”意思,有时on也可以省略。

【例】

  (1)Can we agree the price 我们能不能商定一个价格?

  (2)I agree that your suggestion is quite good.

  我认为你的建议非常好。

  (3)I really can't agree with you.

  我实在不能同意你的意见。

  (4)We agreed on the date for the meeting.

  我们对开会的日期取得了一致的意见。

  (5)After a short time, the program was agreed (on).

  过了一会儿,这项计划大家都同意了。

  (6)He has agreed to our plan for the holiday.

  他已经同意我们的假期计划。

  9. prefer v. 宁愿,更喜欢

  1)跟名词或代词。例如:

  Southerners prefer rice and northerners foods made from flour.

  南方人比较爱吃米饭,北方人比较爱吃面食。

  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.

  他们更喜欢歌颂他们今天生活的新作品。我倾向于小杨的喜欢老歌的意见。这种结构更好一些。

  2)跟不定式。例如:

  I prefer to walk there.我宁愿走路去。

  But people prefer to order their dishes if they have the time.

  但人们更愿意点菜,如果有时间的话。

  At the moment they preferred not to talk about this question.

  在这个时刻,他宁愿不谈这个问题。

  We should have preferred to leave on the 8th, but we didn’t because we had to wait for another classmate.

  我们本来更愿意在八号走的,但没有成功,因为我们得等另外一个同学。

  3)跟V+ ing结构。例如:

  他比较喜欢把业余时间用来认真读点书。

  So you prefer living in the suburbs?

  这么说,你是更愿意住郊区了?

  他们宁愿她不跟他们去。

教学建议二

过去将来时态

一、过去将来时的构成:

  would+动词原形或was/ were going to+动词原形

  如:The farmers didn’t know whether they would have a good harvest.农民们不知道他们是否会有一个好收成。

  Li Mei said that she was going to visit her grandma in the country the next Sunday.李梅说下星期天要去看望她乡下的祖母。

二、过去将来时的用法:

  过去将来时表示从过去某个时间看将来要看发生的动作或存在的状态。具体分为:

  1.主句为过去时,宾语从句常表示将要发生的事情。如:

  Nobody knew what would happen after a hundred years. 没有人知道一百年之后将会发生什么事。

  We didn’t know whether she was going to speak at the meeting. 我们不知道她是否准备在会上发言。

  2.在叙述过去的事情或事情发生的经过时,用过去将来时表示在当时看将来会发生的事。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.一个星期六的下午,一位名叫乔治的年轻人刚离开学校。因为他准备下周开始工作,所以,决定买些新衣服和一双新鞋子。

  3.过去将来时态一般不能单独使用。因为它表示过去和将来双重的时态概念,必须有另一个时态作为比较或衬托。但在一定的上下文中,也可单独使用。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,我在离别三年之后踏上了回家的路。我的全家都会出来迎接我,不久我即将见到我那分别已久的年迈父母。

三、过去将来时的其他表示法

  1.在时间或条件状语从句中,常用一般过去时表示在过去看将来要发生的动作。如:

  They said that they were going to West Hill Farm if it didn’t rain the next Sunday. 他们说如果下星期天不下雨他们就去西山农场。

  The teacher asked Tom what he was going to be when he grew up. 老师问汤姆长大后准备干什么。

  2.go, come, leave, fly, drive, arrive, start等表示位置移动的动词常用过去进行时表示一个当时按计划或安排近期将要发生的动作。如:

  She didn’t say when she was coming again next time. 她没说下一次什么时候会再来。

  Jim decided they were flying to England next month. 吉姆决定他们下个月坐飞机去英国。

数词的表达法

  1—20逐个熟记。

  21~99:先说“几十”,再说“几”,中间加连字号。如:35—thirty-five 69—sixty-nine 。

  101~999:先说“几百”,再加and,再加末尾两位数或一位数。如:

  226—two hundred and twenty-six

  518—five hundred and eighteen

  905—nine hundred and five

  4位和4位以上的数字:先从后向前数,每三位数空半个阿拉伯数字的位置,第一个空前为thousand(千),第二个空前为million(百万),第三个空前为billion(十亿,美式)或thousand million(英式),然后一节一节读出。(或每三位为一段,用逗号分开,第一个逗号前是thousand,第二个逗号前是million,第三个逗号前是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)

  注意在上述这样数词中,hundred,thousand,million等词一般用单数形式。如:

  ten thousand 一万

  a hundred thousand 十万

  a hundred million 一亿

  a thousand million 十亿

  a billion 十亿

  注意:英语没有单独表示“万”和“亿”的单词。表示“一万”要用ten thousand,表示“一千万”要用ten million,表示“一亿”要用a hundred million。

教学建议三

过去将来时的教学建议

  本单元的语法重点是过去将来时。过去将来时是表示对过去某一时间来说将要发生的动作或状况。通常用would或was/were going to+动词原形来表示。如:He said he would go to his hometown for the Spring Festival. 他说他将回家乡去过春节。

  They told me that they would visit China the next week.他们告诉我他们下星期将访问中国。

  She said that she was going to do some shopping the next day. 她说她第二天将去买东西。

过去将来时通常在以下几种情况下使用。

  1.主句为过去时,在宾语从句中表示将来的事情用过去将来时。如第51课中第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:“我当时不知道他们会买另一辆新车。” “我叔叔当时不知道一辆汽车会比一幢房子贵。”

  2.在叙述过去的事情时,在当时看来将要发生的事。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. 她那时是我们的新老师。她那一年就到30岁了。我们非常喜欢她,打算为她举办一次生日聚会。过去将来时还有其他一些用法,教师不必讲得太多,因为这个时态在初中阶段仅要求理解。可以指导学生把一些句子改为过去将来时,如:

  The small children did not know who filled their stockings.

  The small children did not know who would fill their stockings.小孩子们不知道谁将往他们的袜子里塞东西。

  They didn't know what would be in their stockings.小孩子们不知道谁将往他们的袜子里塞东西。

下面一组句子可供教师们作补充练习:

  I didn't know that they would be all there. 我不知道他们都会去那儿。

  They didn't know whether we would win or not. 他们不知道我们是否会取胜。

  He told Jim not to worry. He would take care of Polly. 他告诉吉姆不必担心,他会照看波利的。

  He said he was going to send me a Christmas card. 他说他将会给我寄一张圣诞卡。

  I couldn't decide which school I would go to. 我当时无法决定上哪一所学校。

数字读法的教学建议

  第49课重点训练大数字的读法,除了要向学生讲清楚读多位数字要注意的规则外,还要引导学生通过练习逐渐熟练地掌握,不要急于求成。本单元话题是世界人口问题,为训练多位数字的读法提供了真实、自然的语言情景。

  第49课第一、二部分主要是教学多位数字的引入和练习阶段,可用卡片或把数字写在黑板上的方法教学。教师应引导学生总结读数字的规律。

  Number Chinese English

  l0,000 一万 ten thousand

  100,000 十万 hundred thousand

  1,000,000 百万 million

  l0,000,000 千万 ten million

  l00,000,000 亿 hundred million

  l,000,000,000 十亿 thousand million/billion

  在处理第三部分Ask and answer时,可用世界地图,从中国人口谈起,如:This is China. How many people are there in China? 然后换句话问:What's the population of China? 鼓励学生从上下文中猜测population的词义。引导学生答出:About 1,200,000,000,接下来再问:Do you think it will grow? 等。这样反复练习几个国家后,再让学生打开书分小组做替换练习。

关于阅读课文的教学建议

  第50课课文“只有立足之地”通过介绍世界人口迅速增长的状况,说明控制人口增长的重要性和必然性。可以在让学生打开书前,问一些有关问题,如:

  The world's population is growing very fast. This is a big problem.

  Can anyone tell me why? 引导学生认识到世界人口的迅速增长会带来粮食缺少,就业困难和住房紧张等问题,并由此引出课文题目Standing room only。

  在解释课文题目时,可以让学生打开书看课文插图,或通过切身体会谈人口多的弊病与生活空间狭小的麻烦。可以引导学生通过阅读课文理解课文题目的含义,也可以先初步了解课文题目的意思预测课文中要谈到的内容。有意识地培养学生利用课文题目和课文插图预测课文内容的能力。在阅读课文前,可以给学生一个快速查阅(scanning)的任务,例如让他们在一分钟内,从课文中找出有关世界人口增长的一组数字。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

  阅读课文后,可以让学生分组讨论课文中提出的人口增长的问题,进一步认识到中国实行计划生育(Family planning)政策的必要性和深远意义。也可以做角色表演(Role play),其中一人是《中学生报》记者,另一人是人口问题专家,小记者和专家可根据课文内容就世界人口问题进行问答,然后互换角色。还可留作家庭作业进一步练习、巩固。
