三、知识精要
1）词汇
2）词组
3）语法
【语法点一】billion、thousand、hundred的用法
billion、thousand、hundred若前无具体数字时，后接of，应用复数形式。

若前有具体的数字，则用单数形式。

【语法点二】冠词
in class（在课堂上）in the class（在班里）
in hospital（生病住院）in the hospital（在医院里）
at table（在吃饭）at the table（在桌子旁）
【语法点三】数词
1.基数词：one, two, three……等表示数量
2.序数词：first, second, third……等表示顺序，序数词前一般要加the
3.数词的位置很重要，尤其要注意的是位于another, all之后，位于such, more之前
如：Can you have another two cakes?
I can finish reading two such books in two days.
4.注意事项：
（1）十位数之间通常用连字符“-”，一百以上的数词通常在百位与十位或者个位之间加and，例如231是two hundred and thirty-one
（2）英语中没有万、十万、千万、亿这样的单位数词，英语中习惯从个位往前将三位数划为一组，因此是hundred. thousand, million, billion
5.非整数的表达：
（1）分数的分子一基数词表示，分母以序数词表示，当分子大于1时，序数词要用复数。

其写法和读法如下：
1/2 a/one half
1/3 a/one third
1/4 a/one fourth/quarter
2/5 two fifths
（2）小数是以基数词加小数点表示，小数点前按基数词的规则读，小数点后面的数按个位基数词依次读出：
0.006 zero point zero zero six
0.257 zero point two five seven
148.06 one hundred and forty-eight point zero six
（3）百分数是由基数词加百分号组成，百分号读作percent
0.6% zero point six percent
5% five percent
四、要点讲练
【要点1】prepare的用法
1.vt. 准备
如：He is preparing his speech for the meeting tomorrow.
2.词组搭配：prepare sth for sb
如：My mother is preparing lunch for us.
3.vi为…...做准备.：prepare for sth/sb
如：I was preparing for bed when I heard a knock at the door.
4.prepared adj.准备好的v.准备（prepare的过去分词）
be prepared for为……做准备
be prepared to do sth准备去做
5.preparation n.准备
make/in preparations for为……做准备
make preparations against为对付……做准备
【例题】
1.(2019天津河西区期末考试)

【解析】
考查prepare的意思。

根据意思tony正在为报告准备一些笔记可知时态为正在进行，因此应该选择prepare 的现在进行时态。

【答案】preparing
【例题】
2.Your mother prepared delicious food ______ us. Please say thanks to her.
A.for
B. to
C. in
D. of
【解析】

【答案】A
【即学即用】
1. 用prepare的正确形式及搭配填空

②I am well ______________take the job.
【答案】①prepared② prepared to
【要点2】billion的用法
1.num.十亿
如：He claimed to have seen billions of butterflies.
2.用在数字及several、a few等之后，其复数形式为billion.
3.联系：million（百万）、thousand（千）、hundred（百）
以上这些词如若前面有具体的数字时，后面不加s。

若无具体的数字时，应加s表示“成千上万”、“成百上千的“等。

如：Billions of stars twinkled in the sky.
The population of China is about 1.37 billion.
【例题】
(2019天津中考)
Basketball is so exciting that ________ people play it for fun.
lion
B. two millions
C. million of
D. millions of
【解析】考查数词的用法。

篮球是如此的令人兴奋，以至于数以万计的人乐于玩他。

Million不单独使用，而与具体数连用时要用单数，因此排除A和B选项。

当million表示约数时，应该用复数形式，故选D。

【答案】D
【即学即用】
用billion的正确形式完成句子
①. 1. Exports in June rose 1.5% to a record $30.91 _________.
②. There are one _________ people in that country

A．hundreds B．hundred C．thousand
【答案】
A 考查数词的用法。

固定短语hundreds of“成百上千”；如果前面没有具体的数字，常用复数加of结构表示不确切的数字。

【要点3】too much和too many的区别
1.too much+不可数名词，表示“太多的……”
如：We have too much work to do.
2.too many+复数名词，表示“太多的……”

A.too much : too much
B. too many: too much

【解析】考查too much 和too many 的区别。

Time作“时间”讲是不可数名词，因此第一空应用too much 修饰。

而things是可数名词复数形式，用too many修饰。

故选C。

【答案】C
【即学即用】

A.too many: many too

2）阅读理解
The world itself is becoming much smaller by using modem traffic and modern communication means (通讯设备). Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest is pollution (污染). To pollute means to make things dirty. Pollution comes in many ways. We see it, smell
it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up(用完) or the river was dirty in one place, Man moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
Air pollution is still the most serious. It's bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules (法规) to fight pollution. They stop people from burning coal (煤) in houses and factories in the city, and from putting dirty smoke into the air.
Pollution by SO2 is now the most dangerous kind of air pollution. It is caused (引起) by heavy traffic. It is sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in population at the same time.
1. Our world is becoming much smaller ___.
A. because the earth is being polluted day and night.
B. thanks to science development
C. because of the rise in population
D. because the earth is blown away by the wind every year
2. Thousands of years ago, life was ____ it is today.
A. much easier than
B. as easy as
C. as hard as
D. much harder than
3. Pollution comes in many ways. We can even hear it. Here "it" means ____.
A. water pollution
B. air pollution
C. noise pollution
D. rubbish
4. Air pollution is the most serious kind of pollution because ____.
A. it's bad for all living things in the world
B. it makes much noise
C. it makes our rivers and lakes dirty
D. it makes us angry more easily
5. Which of the following is NOT true?
A. Many countries are making rules to fight pollution.
B. The pollution of the earth grows as fast as the world's population does.
C. If people could go to work by bus or bike instead of car or motorbike it would be helpful in fighting against the problem of SO2.
D. The problem of pollution is not so serious because there are not so many people living on the earth.
答案:1---5 BDCAD
4. 书面表达
自从国家实施二胎政策以来，这个话题引起了很多国人的讨论。

尤其是作为家庭里的第一个孩子们，他们的态度更是说法不一。

假如你的美国笔友Tom想要了解你对于这一话题的想法，请用电子邮件回复他吧！80字左右，开头已给出，不计入词数总数。

提示词：two-child policy
Dear Tom,
As we all know,________________________________________________
范文：
As we all know, the most families only have a child. In fact, I really want to have a brother or sister, because if I have a brother or sister, I will not feel so lonely. So I think two-child policy is a gift for some only child. And if I have some problems, he or she can help me. We can play together and grow up together.
So in the future, when I have my own family, I will be a parent, I hope I will have two children, one is a boy, the other is a girl. They can company each other, and the brother can protect sister if she has some problems. And they can study how to cooperate. When they grow up, we will be old. He and she will also have many babies at that time and we will live in a happy life together.
Thanks for your message. I really want to tell you what I think about two-child policy.
Best wishes,
Li lei。
