【 指点迷津 】
单元重点词汇点拨
1 . population 人口；人数
- What's the population of that city ? 那个城市的人口有多少 ?
- The city has a population of 300 , 3000 . 该市有30万人口。
The population of the city is less than / 200 , 000 . 此城的人口不到20万。
〖 点拨 〗population 作主语谓语通常用单数，但当其前面有百分数、分数修饰时，谓语用复数。have a population of 有……人口。问人口多少有 what 或者 how large 。
2 . following 接着的；以下的
He became quite well the following day . 第二天，他的身体便好了。
Please translate the following sentences into English .
3 . mouth 嘴
Open your mouth , please .
The boy filled his mouth with food .
His mouth is watering . 他在流口水。
〖 点拨 〗复数直接加 s 。have a dirty mouth 说脏话。from hand to mouth 勉强糊口。
4 . beginning 开始；开端
I've read the book from beginning to end . 我已把这本书从头到尾读完了。
The beginning of the book is interesting . 这本书开头很有趣。
Good beginning is half done . 良好的开端是成功的一半。 ( 谚语 )

〖 点拨 〗by the end of 到……末端为止，by the way 顺便说一下。
单元词组思维运用
1 . on earth 在地球上
Two thousand years ago , there were only 250 million people on the earth . 两千年前，地球上只有两亿五千万人。
We live on the earth , but in the future some will be able to live on the moon . 我们生活在地球上，将来有些人可能生活在月球上。
注意on earth 是“世界上；究竟”。如：
What on earth do you mean ? 你究竟是什么意思 ?
He is the greatest man on earth . 他是世界上最伟大的人。
2 . hour after hour 一小时接着一小时，不停地
If the population goes on hour after hour , it will be the biggest problem in our country . 如果人口一小时又一小时地继续增长下去，它将成为我国最大的问题。
So it goes on , hour after hour . In one day , people have to find food for over 250 , 000 mouths more . 随着一小时又一小时地过去，仅在一天内，人们就必须提供25万人吃的食物。
They worked on hour after hour and never left tired . 他们不停地工作，从不感到累。
类似词组还有：day after day 一天又一天 / year after year 一年又一年
3 . at the beginning of 在……初期；在……开头
At the beginning of the twentieth century , the world's population was about 1 , 700 million . 在20世纪初，世界人口大约17亿。
You can find the sentence at the beginning of this chapter . 在这一章的开头你能发现那个句子。
注意at the beginning 是“开始，开头”。如：
At the beginning he wasn't interested in maths . 起初他对数学不感兴趣。
4 . at the end of 在……的末尾；在……的尽头
At the end of the road you'll see the hospital .
At the end of his journey , he went to Shanghai . 在旅行快要结束时，他去了上海。
At the end of 1979 , he came back from Japan . 在1979年末，他从日本回来。
5 . some day 总有一天，有朝一日
Some day you will be sorry about it .
6 . faster and faster 越来越快
The world's population is growing faster and faster . 世界人口增长得越来越快。
注意“比较级 + and + 比较级”表示“越来越……”。又如：
She's getting thinner and thinner . 她越来越瘦了。
7 . no more than 只有，仅有
We have walked on more than ten miles . 我们走了顶多只有10英里。
It took her no more than an hour to write the article . 她仅仅花了一小时就写完了那篇文章。
辨析：not more than 的意思是“至多”，“不超过”。试比较：
There are no more than five students in the classroom . 教室里顶多只有五个学生。 ( 强调“人少”的意思 )
There are not more than five student in the classroom . 教室里的学生不超过五人。 ( 强调“不超过”的意思 )
二、学海导航
【 学法指要 】
单元难点疑点思路明晰
1 . 以介词开头的特殊疑问句句型
By what year will the world's population reach 6 billion ? 到哪一年，世界人口将达到六十亿 ?
介词 by 在此表示“到 ( 什么时候 ) 为止”。在特殊疑问句中，当疑问句作介词宾语时，有时可将介词放在句首。又如：
By whom is the book written ?
At what time did you tell him to meet us ?
From which library did you borrow the book ?
To whom were you talking ?
2 . 不定式作定语的句型
There will not be enough space even to stand in on the earth . 就是在地球上站着，也不会有足够的地方了。
不定式 even to stand in 用作定语，修饰 space . 注意，stand 是不及物动词。当不定式是不及物动词而作定语修饰名词时，它后面就应有必要的介词。如本句型中的 in 。又如：
He still had no house to live in . 他仍然没有房子住。
There is nothing ( for us ) to worry about . 没有什么值得发愁的。
He is a very nice person to work with . 他是一个很好共事的人。
3. the world’s population 世界人口
( 1 ) population 常用来表示一个地区、一个城市、一个国家的总人口数，当 population在句中作主语时，它后面的动词应该用单数形式。如：
What's the population of the world ? 全世界有多少人 ?
Wuhan has a population of about seven million . 武汉大约有七百万人。
( 2 ) people 常用来表示一个较小范围内的具体人数。如：
About two hundred people came to that meeting .
4 . 英语中数词的读法
( 1 ) 大家知道，数字每隔三位数就有一个分节号，分节以后，各节就成了101 - 999第三位数了。第一分节号前是 thousand ( 千 ) ，第二个分节号前是 million ( 百万 ) ，第三个分节号前是 thousand million ( 英国读法 ) 或 billion ( 美国读法 ) ( 十亿 ) 。读的时候十位数 ( 或个位数 ) 的前面一般要加 and ( 也可不加 ) 。因此，333 333 333 读作：three hundred ( and ) thirty - three million , three hundred ( and ) thirty - three thousand , three hundred and thirty - three
( 2 ) 英语没有单独表示“万”和“亿”的词，所以：
10 000 ( 一万 ) 读作：ten thousand
10 000 ( 十万 ) 读作：one hundred thousand
10 000 000 ( 一千万 ) 读作：ten million
100 000 000 ( 一亿 ) 读作：one hundred million
5 . About eighty - one million 是 The population of Germany ( 或 It ) is about eighty - one million 的简略形式。
6 . … and find out the answers to these questions . ……并找出这些问题的答案。
( 1 ) 辨义：find 与 find out
find 多用于直观所“发现”或“找到”的东西；find out 则强调通过思索、调查等所发现的事物。例如：
I haven't found my pen yet .
We must find out the result of the thing .
( 2 ) 句中的介词 to 表示一种对应或配套关系，不可用介词 of 。例如：
This is the key to the front door . 这是前门的钥匙。
Where is the monument to Liu Hunan ? 刘胡兰纪念碑在哪里 ?
7 . Standing room only 只有立足之地
room 在这里意为“空间，地方”，为不可数名词。例如：
The bed takes up too much room .
8 . By what year will the world's population reach 6 billion ? 到哪一年，世界人口将达到60亿 ?
( 1 ) by“到……止；不迟于”。例如：
By the end of last year , they had learned about one thousand English words .
I'll be back by ten o'clock . 我将10点钟以前返回。
比较：I'll be back at about ten o'clock . 我将于10点左右返回。
( 2 ) 在特殊疑问句中，当疑问词作介词宾语时，有时将该介词置于疑问词前。例如：
With whom were you talking just now ? 刚才你和谁交谈 ?
From which library did you borrow the book ? 你从哪个图书馆借的这本书 ?
9 . Maybe you think that isn't many . 可能你认为174个婴儿并不多。
名右的 that 代替前面提到的 174 babies，这是一个具体的 number ( 数字 ) ，作为一个整体，代词用 that 而不用 those 。例如：
He's learned about five thousand English words . That's really a big number .
The child has learnt hundreds of English words . That isn't easy for him .
10 . So it goes on , hour after hour . 人口出生就这样一小时一小时的延续下去。
( 1 ) so“如此”的意思。it 指上文提到的人口出生。
( 2 ) go on “继续不断”的意思。可作及物或不及物动词词组用。例如：
The work went on well . 工作进行得很好。
Peter went on doing his homework though he was tired .
( 3 ) hour after hour “一小时接一小时。例如：
day after day 一天天 ，year after year 一年又一年
11 . In one day , people have to find food over 250 000 mouths more . 每过一天，人们就不得不为增加的25万多张嘴寻找食物。
( 1 ) 句中的 in 与表示“所用的”时间连用。例如：
She finished reading the book in a week . 她用一星期时间看完了这本书。
( 2 ) 介词短语 over 250 000 mouths more 是介词 for 的宾语。例如：
250 000 mouths more“多25万张嘴”。注意这种表达结构，其中的 more 表示数量的增多。例如：
We don't hear clearly . Please read the text once more .
They've learned about one thousand English wors . And we've learned two hundred more . 他们学了约 1000 个英语单词，我们还多学了 200 个。
( 4 ) 介词 over 可作“多于”、“超过”之意。例如：
It cost me over ten yuan .
12 . Just think how many more there will be in one year ! 想想看吧，在一年时间里将会增加多少人 !
( 1 ) just 常与祈使句连用。例如：
Just come here a moment . 请到这儿来一下。
( 2 ) How many more there will be in one year 是动词 think 的宾语从句。
13 . The population problem may be the greatest one of the world today . 人口问题可能是当今世界最严重的问题。
( 1 ) the greatest one 即 the greatest problem , one 为代词。
( 2 ) 介词短语 of the world today 是 one 的定语。
14 . The world's population is growing faster and faster . 世界人口增长得越来越快。
( 1 ) grow 意为“增长，增大”。句中用进行时 is growing , 很好地表达了当今世界的人口状况。
( 2 ) faster and faster 是副词重叠，修饰 is growing，作状语。副词和形容词比较级的这种重叠使用，相当于汉语的“越来越……”。例如：
The train ran faster and faster . 火车开得越来越快。
15 . But at the beginning of the twentieth century …，然而在二十世纪初……
at the beginning of…“在……之初”。例如：
At the beginning of the class , the teacher drew a picture on the blackboard .
在开始上课的时候，老师在黑板上画了幅画。
16 . A Un report says that world population will pass six billion by the end of the twentieth century . 一份联合国报告表明，到二十世纪末，全球人口将超过60亿。
( 1 ) Un＝ ( the ) United Nations“联合国”
( 2 ) pass 意为“超过”。例如：
Run faster , or Li Ming will pass you .
( 3 ) pass 通常还作“通过”、“经过”之意。例如：
We all passed the exam last week .
17 . People say that by the year 2010 , it may be seven billion . 人们说，到 2010 年，世界人口可能达到 70 亿。
( 1 ) by“到……为止，不迟于”。
( 2 ) 句中的 2010 是 the year 的同位语。例如：
the year 1949 一九四九年，the year 1997 一九九七年也可说 the year of 1949 , the year of 1997
这里的介词 of 表示同位关系。
18 . There will not be enough space for anybody else . 再也没有足够的空间来容纳任何其他的人了。
anybody 为不定代词，副词 else 修饰不定代词必须后置。
19 . the more developed countries 比较发达的国家
the less developed countries 不太发达的国家
20 . Which country has the larger population , Canada or Australia ? 哪个国家人口多些，加拿大还是澳大利亚 ?
population 一词指的是总人口 ( 见本单元 1 ) ，所以，说人口多就用 large population 或 big population , 反之就用 small population 。
21 . population ( in hundred million ) 人口 ( 以亿为单位 )
介词 in 表示“用……方式”。例如：
( 1 ) Answer my question in English , please ?
( 2 ) Look , the students are standing there in rows .
22 . There will not be enough space even to stand in on the earth . 地球上将连站立的空间都不够。
( 1 ) 不定式 even to stand in 是 space 的定语，而 space 在逻辑上 ( 或意义上 ) 则是介词 in 的宾语。这种结构中的介词是不能没有的，因为 stand 是不及物动词，不能接宾语，要特别注意。
我们可以说 stand in space 而不能说 stand space 。
( 2 ) 当上面结构中不定式的动词是及物动词时，则不能用介词。例如：
I've some important letters to write .
23 . 同义词 hear 与 listen 的区别。
hear 与 listen 这两个词都是动词，都有“听”的意思。但意思有区别，用法也不同。
hear 是及物动词，表示“听见”，“蝗到”，可能是有意识的听，也可能是无意误解的听。
Louder , please , I can't hear you .
We heard someone laughing in the next room .
hear 还可作不及物动词，后接 of ( about ) 表示“听别人说” ( 指间接听到 ) ；后接from 意 思是“收到 ( 某人 ) 的来信”。如：
I have never heard of such a thing . 我从未听说过这种事。
Have you still not heard from him ? 你还没有收到的来信吗 ?
listen 是不及物动词，表示有意识或注意地“听”，交不说明是否听见的结果；必须加 to 才能接宾语。如：
He often listens to news on radio .
I listened but heard nothing . 我注意听了，但什么也没听见。
24 . 相似词 after , in , later 的区别
after 作介词表示在“某时间之后”， ( 1 ) 它可以表示“在过去的一段时间之间”。 ( 2 ) after 后面不用将来时，而是用现在时态表示将来的含义。如：
She went after three days . 她是三天后走的。
I'll phone you after I arrive . ( or : after I have arrived . ) 我到了之后，给你打电话。
但不说：She will go after three days .
也不说：I'll phone you after I'll arrive .
in 表示从现在起，将来的某时间之后。如：
I will come and see you in five days . 五天以后我来看你。
later 用作副词，常用在过去时的句子中，表示“一段时间之后”。如：
She came a few minutes later . 她几分种后就来了。
later 也可用在一般将来时中。如：
You will realize your mistake later .
你以后会认识到你的错误。
I shall call on you three months later .
三个月后我来看望你。
25 . 同义词 field , ground , earth , land 的区别
( 1 ) field ( 土地，田地 ) ，指可以耕种和种植农作物的土地。
The peasants are working in the fields .
( 2 ) ground ( 地，土地，地面 ) ，主要指大地、陆地的表面，也可以指土壤、场
地、泥土。指陆地时，土地、沙地、水泥地都可用这个词。
The little boy was lying on the ground .
( 3 ) earth ( 土，土地，泥土，地面 ) ，可用作“大地”，以别于天空。用作“地面”，以别于海、洋、大气和天空。还可用作“泥土”，以别于坚硬的岩石。earth 还可作“地球”解。如：
The house is built of earth . 这房子是用土筑成的。
The earth is bigger than the moon . 地球比月亮大。
( 4 ) land ( 土地，地面，田地 ) ，作陆地、大地讲时，是河流、海洋的相对用词。用以指土地或土壤时，着重指它的性质、用途，即可耕种的田地。如：
Are you going by land or by sea ? 你走陆路或是海路 ?
Fish cannot live on land . 鱼不能在陆地上生活。
He owns a lot of land , but he never works on the land . 他拥有许多土地，但他从不耕作。
26 . 数字表达法
注意英语和汉语在表示数字上的异同：
英语和汉语在表示“百”、“千”、“百万”、“十亿”时分别有相应的单词，如 hundred ( 百 ) ，thousand ( 千 ) ，million ( 百万 ) ，billion ( 十亿 ) 。但在英语中，没有单独的词表示“万”和“十万”，而要用“ten thousand”表示“万”，用“one hundred thousand”表示“十万”。例如：
数字 汉语 英语
100 一百 one hundred
1 000 一千 one thousand
10 000 一万 ten thousand
100 000 十万 one hundred thousand
1 000 000 一百万 one million
10 000 000 一千万 ten million
100 000 000 一亿 one hundred million
1 000 000 000 十亿 one billion
1 200 000 000 十二亿 one billion and two hundred million

A Foolish Man Buys Shoes
There was once a foolish man . One day he wanted to go to the market to buy a new pair of shoes . He first measured his feet with a ruler and then took a piece of thread the length of his feet on it . He was in such a hurry to set off that he left the thread of home .
At the market , when arriving at a shoe store , he felt in his pockets , but he only found that thread wasn't in . So he said to the shop assistant in a regretful voice , “I've left my measurement at home , so I don't know the size , I'll have to go back for it . ”With these words , he hurried off .
He hurried home for the thread and then ran back to the market . It took him a lot of time in the trip home and back . By the time he reached the market , it was almost dark and the market was already over . He had gone to all this trouble for nothing , failing to buy the shoes .
Then someone asked him , “Do you want to buy the shoes for yourself or for someone else ? ”
“For myself , of course ! ”he answered .
The man asked him , “Well , but haven't you brought your feet with you ? What do you need to bring the measurement for ? ”

过去将来时态
过去将来时的动词表示对过去某一时间来说将要发生的动作或呈现的状态。这个时态常用在宾语从句中。过去将来时有以下几种形式：
1. should / would + 动词原形
He said he would be there before Sunday . 他说他星期天以前将在那里。 ( be 动词肯定式 )
I hoped I should not go the next week . 我希望下星期我不去。 ( do 动词的否定式 )
注意这个时态是一个相对的时态，立足于过去某时，从过去的观点看未来。
2. was / were going + 动词不定式
过去将来时的这种表达形式可以表示过去曾经打算或计划准备要做的事。如：
They told me that they were going to have a picnic . 他们告诉我他们将要举行一次野餐。
They were going to have a meeting . 他们曾经打算开个会。
过去将来时的这种形式可以表示过去将要发生或很有可能发生的事，但未实现的动作。
I was just going to ring him up when he came . 我刚要给他打电话，他就来了。 ( 电话没打成 )
有时也用 was / were + coming 表示过去将来时，如：
I didn't know when they were coming again .
3. was / were + 动词不定式
was / were about + 动词不定式
Mary was to meet Jack at the street corner . 玛丽将在街道拐角处同杰克见面。
We were about to leave when the telephone rang . 我们正要走，电话铃响了。

二．教学重点
1.含有情态动词的被动语态
2.neither…nor; stop…from doing sth; 等
3.部分日常用语
三．教学难点
含有情态动词的被动语态
四．重点难点讲解
1．_ neither too wet nor too dry. 既不要太潮湿也不要太干燥。
both 和neither
1)both表示“两者都”，即指两个人或物，是复数概念；neither“两这种无一”，也指人或物，然而是单数概念。因此，both修饰复数名词，谓语用复数形式；neither修饰单数名词，谓语用单数形式。如：
Both answers are right. 两个答案都对。
Neither answer is right. 两个答案无一是对的。
（第二句是第一句的全否定形式。它的不完全否定形式是这样的，
Both answers are not right. 两个答案并不都对。）
I like both of them. 他们两个我都喜欢。
I like neither of them. 他们两个我都不喜欢。
（如果数量是三个或三个以上，则肯定句用all,否定句用none。如：
All of them are interested in it. 他们对此都感性趣。
None of them are(is) interested in it. 他们对此都不感性趣。
2）both…and…和neither…nor…可以连接两个并列成分，即两个主语，谓语，宾语或其他并列成份。如：
She can both sing and dance. 她既会唱歌又会跳舞。
She can neither sing nor dance. 她既不会唱歌又不会跳舞。
Both Tom and John are from Britain. Tom 和John都是英国人。
Neither Tom nor John is from Britain. Tom和John 都不是英国人。
（both…and…连接两个主语时，后面谓语用复数。而neither…nor…连接两个主语时，后面 谓语必须与nor后面的主语在数上保持一致。如：
Neither Jack nor his parents are interested in the girl.
Jack和他的父母对那个女孩都不感兴趣。
2．happen to sb./sth.
表示某人或某件事情发生了什么情况。很多时候表示一种偶然性。
happen的主语一般是疑问代词what ，不定代词something, anything,nothing,以及某些表示消极意义的名词。
happen是不及物动词，不能用于被动语态。
Happen总是和介词to搭配。如：
1)What has happened to Mary? She isn’t here yet.
Mary出了什么事？她现在还没到。
2）If anything happens to the machine,please let me know.
如果机器出了什么毛病，请通知我。
3）The accident happened to him at three this afternoon.
他出事是在今天下午三点半。
3．… about a third was… 大约三分之一是…….
分数的表达法
分子用基数词，分母用序数词。如果分子是二或二以上的数，分母加-s.如：
one-third 三分之一
two-thirds 三分之二
分数作主语，谓语的单复数取决于它所代表的量是单数还是复数。如：
Three-fourths(Three quarters)of the students of our school are boys.
我们学校四分之三的学生是男生。
Three quarters of the work has been done.
工作的四分之三已经完成。
4．hundred和hundreds of
hundred前面可以用表示具体概念的数词来修饰。而hundreds of表示“多”， “数以……计”，前面不可一家表示具体概念的数词。如：
There are two hundred students in our grade. 我们年级右二百个学生。
Several millions of trees are planted in our country every year.
我国每年将种植好几百万棵树。
5．Stop…from doing
stop sb./sth.from doing sth.是“阻止……不作某事”，介词from可以省略。如：
We must stop him (from)doing such a foolish thing.
我们必须阻止他不让他作这样的蠢事。
They tried to stop such a thing (from)happening.
他们向阻止这样的事情发生。
6．stop to do和stop doing
stop to do的意思是“停下来做事情”，不定式做状语。
stop doing的意思是“停止做事情”。如：
They stopped to talk to me. 他们停下来和我讲话。
Stop running about! 不要乱跑。
7．the more, the better越多越好。
前一分句表示假设，条件，时间等，后一分句表示结果。如；
The more you read,the more you will get. 你读的越多，得到的也就越多。
The farther he walked, the stranger he felt. 她越往前走，越感到奇怪。
8．thanks to … “多亏了……”,“由于……帮助“。如：
Thanks to the English language, we can learn a lot from English-speaking countries.
由于英语这门语言的帮助，我们能够向说英语的国家学到许多东西。
I’ve passed the exams thanks to my teachers. 多亏了我的老师，我通过了这次考试。
9．不定式作定语
1）I have a lot to do today. 我今天有许多事情要做。（a lot是do的逻辑宾语）
2）I have three letters to write this evening. 今晚我有三封信要写。
3）She is a nice person to work with. 她是一个很好共事的人。
4）Let’s find a room to put these things in. 我们找个房间把这些东西放在里边。
（前两个例句的不定式是及物动词，后两个例句的不定式时不及物动词，它后面就应加上必要的介词。）
10….as often as possible 尽可能常……
as soon as possible 尽可能地快
as far as possible 尽可能地远些
11．Today, too many trees are still being cut down in the USA.
今天在美国人有大量树木继续被砍伐。
be+being+过去分词是现在进行时的被动语态，表示“正在被……” 如：
The silk is being produced by the factory. 这个工厂正在生产丝绸。
12．The Great Green Wall is 7,000 kilometres long, and between 400 and 1,700 kilometres wide.
这绿色长城长为7，000公里，款再次00指，700公里之间。
表示计量的方法是：数词+metres/kiometres+long/wide/deep/high/tall…
表示重量可用数词+kiograms+heavy 如：
The class room is 4 metres wide. 这个教室有4米宽。
The river is about 10 metes deep. 这条河有10米宽。
13．There are twenty more trees to be planted!
还有20可树要种呢！
to be planted是动词不定式的被动式，作明词trees的定语。动词不定式作定语时，通常放在被修饰名词之后。如：
We have a lot of food to eat. 我们有许多食物可吃。
I have many books to read. 我有许多书要看。
