三、教学重点（依靠教学大纲）
（1）分数、百分数的正确写法
（2）三种表达倍数的句型
（3) 修饰比较级的程度副词
四、教学难点
（1）倍数句型中“倍数”的位置问题
（2) 如何高效记住能放在比较级前的程度副词及他们的区别
五、教学策略
先说教法
1、信息收集法?
2、问题发现法? 探究问题的方法
3、分组讨论法? 将学生分成若干学习
4、榜样示范法
5、图示法
再说学法
自主探究法。自己读出不同分子的分数。让学生讨论得出分数的读法规则。让学生在英语课堂上找到成就感。树立学习自信心
观察发现法。在学习放在比较级前的程度副词时，通过教材上列出的程度副词，让学生观察他们的特点，最终得出结论。培养学生更有效学习的能力。
任务型合作策略。在学习倍数句型时，将学生分为三大组，每个组负责讨论并派代表写出三个句型中的一个句式。发展学生与人合作的意识和能力。
六、教学准备
学生提前预习本模块知识，教师提前充分准备本模块相关知识材料。

3、课堂练习
要求学生当堂做课本P45的课后练习。
4、课堂活动
1times 第一组数字中，数字B和数字A的关系引出倍数，这样不会突兀，很自然的将读书字过度到了语法倍数句型的学习。具体做法是
(将学生分为三组，复习并讨论在第一模块中学习的倍数句式，派代表写在相应的位置，学生有能力这么做，给学生一个表现自己的机会)
2 借助前面的数字提问题在GROUP ONE 中，WHICH IS easiest to read ,and which is hardest? So we can say “the longer ,the harder ro read)
5、课堂小结
得出结论:the+er, the +er,(越。。。， 越。。。)
结论2（from number a to number f, it becomes more and more difficult to read.）
Ee+and + er (越来越)

九、教学反思
这节课从导入（告诉学生将上一堂数学课，引起学生的好奇心）就调动了学生的学习积极性。先从最简单的整数开始，因为简单，这就打消了后进生放弃学习的心理从而照顾到了大多数的学生。我之所以选择数字“1”是因为它的英语发音有点象汉语的狗叫声，也是为了能够更有力得调动学生主动性。在学习完多位整数读法后很直接的过度到了本节课的重点：分数和百分数的读法和写法。依旧利用黑板上的那几组数字很自然得过度到了语法（比较级句型）的学习。整节课过度自然，各环节环环相扣。教学内容也是难易得体，既照顾到了后进生，也满足了尖子生对新知识的渴求，尤其是一些特殊比较级句型和放在比较级前程度副词的拓展，使得学生对比较级的用法有了一个宏观的认识。整体来说，这是一节成功的课，因为我做到了以学生为主体并创造了让每个学生都有机会证明自己“我行”的教学遵旨。

Step Ⅰ Lead-in
The purpose of this part is to let the students know and get familiar with the new words in INTRODUCTION: expand, contract, mixture, substance, oxygen and electricity. First, write down the words on the black-board, and then teach them the meaning of each word by questioning.
T: Hello, everyone! Do you know the program Lucky 52 on CCTV?
Ss: Yeah!
T: OK, now suppose I’m Li Yong, and you are competitors. Here are six words on the blackboard. What you should do is to guess the meanings of them. If you can’t express them in English, you may say in Chinese. The quicker, the better. Are you clear?
Ss: Yes.
T: Listen. What do we take in when we breathe?
S1: Air.
T: Right. But not exact.
S2: 氧气。
T: Right. In English, it is called “oxygen”. We need oxygen to keep alive. And without it, there will be no life on this planet. OK, another question. What do we call it when we put sugar, eggs, and milk together, or we mix them together?
S2: We call it mixture.
T: Good. All the things that are mixed together can be called mixture. Next one, we can use one word to stand for all the things around us, which includes air, water, stone, wood, glass, iron and so on. What is this word?
S3: Substance.
T: Right. Next, what will happen when water turns into ice?
S4: Liquid will turn into solid.
T: Right. Besides this, will it have some change in size?
S5: Yes. It will become larger.
T: Yeah! What do we call this change?
S6: It’s called “expand”.
Teacher can use body language to express the meaning of “expand”.
T: Now, the last one. What’s the opposite meaning of “expand”?
S7: Is it “contract”?
T: You are right. The meaning of “contract” is making or becoming smaller or shorter. Well, I think that all of us did very well. Now please read these words after me.
...
Step Ⅱ Vocabulary
Ask the students to read the sentences in Activity 1 on page 41, and then pick out the correct ones. At the same time ask them to pay attention to the new words. At last check the answers to Activity 1 with the whole class.
For Activity 2, ask the students to work in pairs to finish the task. If possible, ask them to give their rea-sons for doing so. For Activity 3， give the students more words to help them know that materials are around all of us, and we should use them correctly and reasonably.
T: As the saying goes: Birds of a feather flock together or things of one kind come together. Now we’ll put the words in Activity 2 in pairs or groups, just like the pairs in Example. If possible, give your reasons to do so. It is a good chance for us to get familiar with these words. OK, I’ll give you one or two minutes to do the job.
Two minutes later.
T: Have you finished the task?
Ss: Yes.
T: Who’d like to read out your answers?
S1: We’d like to put air, gas and oxygen together, because all of them are gas. And we put earth, sun and moon together, because all of them are planets.
T: Quite right. How about you two boys’ answers?
S2: We put gas, liquid, and solid together, because we think they are the three states of substance. And we also put contract and expand together. The two words have opposite meanings.
T: I’m very glad that you can finish the task so quickly and correctly. Well, all of us know that we are living in a material world. Without these materials, whether natural or man-made, we’ll have nothing to eat, to live in, to use, to wear and so on. Now, let’s look at these words: electricity, iron, metal, steel, air, and glass in Activity 3. You have to tell which of them are natural, which of them are man-made and which of them can be both.
S3: Air, iron and some metals are natural. Steel, some metals and glass are man-made. And electricity can be man-made and natural.
T: Why do you think electricity is both man-made and natural?
S3: Because in a storm, we can see lightening in the sky. While the electricity we are using in everyday life is from electric works. So I think electricity is both man-made and natural.
T: Well, it’s a good answer. OK, can you say some other things that are man-made?
Ss: There are too many such things.
T: Give us some examples.
S4: Cars, machines, man-made satellites, plastics and so on.
T: Do you know man-made beauty?
S6: I know it. Some ordinary-looking girls can become beautiful overnight.
T: Do you think it is necessary to do so?
S7: It’s difficult to say. But I think to have a beautiful mind is more important than to have a beautiful appearance.
T: I agree with you. It is said that a woman with a beautiful mind is more beautiful than a woman with a pretty face.
Step Ⅲ Reading (Passage A: P44)
There are three activities in this part: Activity 1: find the correct order to describe the stages of a scientific experiment; Activity 2, find the best title for the passage; Activity 3, answer some questions about the passage.
Task 1: Activity 1
T: Well, if you were an engineer, you would take part in the experiment of making Shen ZhouⅤ Flight. What kind of materials would you like to use?
S1: I’d like to use some materials that are light enough and hard enough, so that the flight can be easily sent up into space, and doesn’t get in trouble.
T: How can we find such kind of materials?
S2: We can do some experiments. We can’t use natural materials only; we need both man-made and natural materials.
T: That’s right. Now we’ll read a passage about a scientific experiment. Please turn to page 44. We’ll go through Passage A. When we are doing a thing, we should do it in an orderly way. It’s especially true with a scientific experiment. Now let’s see the four words in the table: conclusion, aim, result and method. The four words are about the orders or stages of a scientific experiment. We must know these two words: result and method. What are the meanings of the other two words?
S3: “Aim” should be about what the experiment is for. For “conclusion”, I have no idea.
T: Right. “Aim” means purpose or object. For example, he has only one aim in life, that is, to be a millionaire. And for “conclusion”, let’s see an example first, when you have worked on a maths problem for a long time, but you still can’t work it out. So you may make a conclusion that the problem is wrong. Here, “the problem is wrong” is your conclusion. Do you understand?
Ss: Yeah!
T: Now who can give us some other examples to show the meaning of “aim”?
S4: Many people aim to be a millionaire. But I think to serve people is the highest aim.
T: What is the correct order of stages to do an experiment?
Ss: It should be aim, method, result and conclusion.
T: That’s right. Without aim, we don’t know where to go; without method, we don’t know how to do things well; without result, we’ll draw a blank or gain nothing; without conclusion, we’ll find what we’ve done is worth nothing.
Task 2: Activity 2
Ask the students to scan Passage A and find the best title for the passage.
T: Please look at Activity 2. What you should do is to scan Passage A and decide which is the best title for the passage.
Give the students some time to do the job and then check the answer.
T: Well, what’s the best title for the passage?
S4: The Reaction of Metals.
T: Why?
S4: The writer begins the passage by introducing the different uses of different metals. But for the rest part of the passage, including the table, he / she mainly describes several metals’ reaction with different substances.
T: What a good reason it is! Now, let’s look at Activity 3.
Task 3: Activity 3
Ask the students to read and answer the questions below the passage. Give them some time to do the job. After that, check the answers with the whole class.
Step Ⅳ Reading (Passage B: P45)
In this part, the students will read the passage and then fill in the table below the passage.
There are three Tasks in this part. The first one is to ask the students to find the structure of the passage and finish the table. The second one is to deal with Activity 5. The third one is to finish Activity 6.
Task 1: Structure of the passage
T: Now, we’ll continue to read Passage B. The title of it is A Simple Scientific Experiment. From the passage we can see how the experiment is done. What is the structure of a description of experiment? Who can come to the blackboard to write down the structure?
S: Let me try.
A student comes to the blackboard and writes down the structure.
A Simple Scientific Experiment:
Introduction → Aim → Apparatus → Method → Result → Conclusion
T: OK. We should notice that there are 3 different reactions which are respectively described with method, result and conclusion. Now, please read the passage and then fill in the table.
Let the students do the job, and then check the answers with the whole class.
T: Well, what is ordinary water according to the experiment?
S6: I think ordinary water here means the water that has not been boiled, and has air in it.
T: Right. We also call ordinary water “raw water”. Now what’s “Bunsen burner”? We often find it in labs. Now, turn to page 46, and find the picture of Bunsen burner.
Task 2: Activity 5
T: Now please turn to page 46. Look at Activity 5. Read Passage B again. Complete the sentences.
After the students finish the sentences, ask some of them to read out the complete sentences and check the answers with the whole class.
Task 3: Activity 6
This part is about vocabulary study. Let the students read after the teacher, and then work in pairs to find the meanings of the new words.
Explanations of some words:
React: have effect on (of one substance applied to another)
Steam: gas from boiling water
Oil: liquid which does not mix with water, obtained from animals, plants or found in rock under-ground
Boil: (of water or other liquid) reach the temperature at which change to gas occurs
Scientific: of, for, connected with, used in science
Experiment: test carried out carefully in order to study what happens and gain new knowledge
Float: be held up in air, gas or on the surface of liquid; move with liquid or air
Form: give shape or form to; make, produce
Dissolve: (of a liquid) soak into a solid so that the solid itself becomes liquid
Step Ⅴ Language Points
Ask the students to translate the following sentences, and get familiar with the sentence structures.
Show the following sentences on the screen.
1. It is hard to think of a world without metals.
2. It is important to know how they react with different substances, for example, water
and oxygen.
3. This makes sure there is no air in the water.
T: Before we finish this class, let’s look at the screen. There are three sentences on it.
Can you translate them into Chinese?
Let the students translate the sentences into Chinese.
T: OK. In fact, these sentences involve two sentence structures. One is: it is + adj. + to do something. The other is an object clause. Now let’s look at more sentences to get familiar with the two sentence structures.
Write down the structures on the blackboard and then show the students more sentences on the screen:
1. It’s hard (difficult) to say which is better.
2. It’s foolish (silly) to act like that.
3. It’s easy to learn a foreign language.
4. It’s impossible to finish the job in one day.
5. It’s wrong to steal.
6. I only came to make sure that everything was all right.
7. Father makes sure that all the lights are off before he goes to bed.
8. Make certain that your facts are right.
9. We must make certain that she can come.
Let the students translate the sentences. If they have any difficulty, give them some help.
Step Ⅵ Homework
T: Today, we have learned some new words and two passages about scientific experiment. After class, please do Exercises 6, 7 and 8 on pages 92&93. These exercises can help us remember the new words and expressions about scientific experiment. OK, that’s all for today. See you next time.
Ss: See you.

Discussion and pair work.
四、Teaching aids 教具准备
A computer and a projector.
五、Teaching procedures &ways 教学过程与方式
StepⅠ Revision
Check the students’ homework.
For these two exercises, ask the students to read out the complete sentences.
T: From Exercise 4, we know that we can use much, a bit, a lot, a little to modify the comparative expressions. Besides these, we have other words to do this. Now please look at the sentences on the screen. Read the sentences and pay attention to the bold face.
You have far more imagination than I have.
It’s slightly warmer today.
She’s actually a good deal older than she looks.
Do you feel any better today?
She was no older than Zilla.
You must go and get some more milk.
He is fat, but his brother is still fatter.
This book is even more useful than that one.
My sister is ten years younger than me.
You’re a head taller than Jane.
It was one-fourth cheaper than the market price.
After the students have finished reading, ask them to make a conclusion of the words to modify the comparative degree.
T: By now we’ve learned many words that can modify the comparative degree. What are they?
S1: They are much, a lot, far, a bit, a little, slightly, any, no, some, even, still, a head, ten years and so on.
T: Yeah, that’s right. Now, that’s all for the home-work. Let’s come to Reading.
Step Ⅱ Lead-in
T: Do you know this man?
S1: He is Ting Zhaozhong, a world-famous Chinese scientist. He once won the Nobel Physics Prize.
T: That’s right. He is a top-class scientist. Many outstanding scientists think it is an honor to work with him. What he often says is “I don’t know”. We know science is a serious thing. You can’t be too careful in it. I think this is the real spirit that a scientist and the person who aims to be a scientist should have.
Step Ⅲ Reading (P94)
Task 1: Fast reading
T: Now let’s turn to page 94 to see what happened in the chemistry lab. First, read the three summaries about this passage on page 93. After reading the passage quickly, choose the best one.
Give the students some time to read the passage.
T: Which one do you think can be the best summary of the passage?
S1: No. 1 is the best summary, I think.
T: Good.
Task 2: Careful reading
The purpose of this task is to answer the eight questions in Exercise 11, and let the students get familiar with some new words in this Module.
T: Now, let’s read the questions in Exercise 11, so that you can know what you should do when you are reading. Now read the passage carefully and find the answer to each question. Mark where the answers are and then number them. So that you can find them quickly when you need these answers.
Let the students do the job in pairs. One asks the questions and the other answers them. While the students are asking and answering the questions, walk around the classroom to see if they need any help. And at the same time, collect the answers.
Step Ⅳ Discussion
T: Well, you often do some experiments in your science lessons, right? Did any incidents happen? Now I’ll give you some time to discuss the incidents that have happened in your science lessons.
After a while.
T: Who would like to report an incident that happened before?
S1: I’d like to. One morning, we were doing a chemical experiment in the school lab. We fetched some solution(溶液) from the cupboard, including oil of vitriol(浓硫酸), and put them on the table. Wang Hua and Ding Ding were in the front row. Xiao Ming and I were in the second row. Suddenly, Wang Hua turned to say something to me, and turned over the bottle with oil of vitriol by accident. The bottle was not covered! The oil of vitriol splashed. Soon a hole was burned in Xiao Ming’s coat. And his hand was burned to black. He screamed. We were so worried. The teacher ran over to send Xiao Ming to the nearest hospital.
Fortunately, nobody else was injured in the incident. However, it taught us a good lesson. Never leave a bottle uncovered on the table.
S2: I’d like to tell you about one of the incidents in our chemical experiment. In the experiment, we used Bunsen burner. After the experiment, one of my classmates forgot to cover it. About ten minutes later, a teacher passed the laboratory and smelt the odd smelling. She immediately entered the lab and put out the fire. Fortunately, no further incident was caused. After that all the teachers and students were gathered to have a meeting. The headmaster gave a talk to em-phasize the importance of safety in lab. That’s a good lesson.
T: Yeah, if the teacher didn’t notice the incident, it would have been a terrible fire. We often think it’s impossible to make an accident. But as a saying goes, “It’s not too careful to do a thing.” We should always keep the saying in mind.
Step Ⅴ Cultural Corner
T: In this Module, we’ve learned many things about scientific experiment. Maybe some of you find it interesting, because you are interested in science; while others may find it’s dull, because they prefer art lessons. In our class, who enjoy study-ing science? And why?
S1: I like studying science. I like maths best. When I work out a problem, I feel very happy.
S2: I like chemistry. It’s very interesting to see that you add one substance to another, and they react and change into a new substance. That is fantastic!
T: Knowledge is power. Whatever subjects you enjoy learning, you should devote yourselves to them. Or you won’t make any achievement. Now let’s turn to page 49. Read the passage and answer this question: Why has Mark become more interested in science?
Give the students some time to do this in pairs, and then check the answers.
T: Are you ready to answer the question?
Ss: Yeah!
T: Why has Mark become more interested in science?
S3: I think there are two reasons. One is that the science facilities are very good in the new school, with laboratories that have all the latest equipment. The other is that they have four chances each term to public science lectures, and the lecturers are people who have made real discoveries in their area of science. I think Mark is a lucky person.
T: Yeah. Situations can change a person. In fact, we also have the same chance to learn some knowledge outside class. Channel 10 on CCTV offers a lot of lectures about science and art. Some are given by famous professors. One of my favorite programs is “百家讲坛”. If you often watch it, I believe you’ll benefit from it.
Step Ⅵ Summary and Homework
T: We have learned a lot about scientific experiments. Nowadays, it seems that most people prefer science, because they think science can bring financial benefits, while they do not pay much attention to morality, ethics and love. As a result, there are many disasters and wars in the world. So when we are learning science, we should also pay attention to morality, ethics and love. Today’s homework is to preview PRONUNCIATION and EVERYDAY ENGLISH. OK, time is up. So long, everyone.
Ss: So long, teacher.
六、板书设计
重点词汇：used to, in the area of, be proud of, be supposed to, facility, crucible, balance, tongs, react, stage, mixture, set up
重点句式：The hotter the mixture, the quicker the reaction. P94
Continue to heat the mixture until the water evaporates, leaving the salt in the crucible.
重点语法：used to
七、教学反思：
这节课的学习，不仅达到了生生互动的效果，也体现了师生互动的优势。整体来说，这是一节成功的课，因为我做到了以学生为主体并创造了让每个学生都有机会证明自己“我行”的教学遵旨。

without hesitation, the bag on
the floor and in the dark.
A.left;lied;disappeared
B.leaving;lying;disappeared
C.leaving;lie;disappearing
D.left;lay;disappear
解析 分析句子知leaving the bag...是分词
短语作状语；而the bag和lie间是主谓关系，
故用lying的形式；而disappear和rush out是
句子的谓语动词；因此B正确。B2.There are both advantages and
disadvantages in the scheme proposed,but
I think we should benefit by
adopting it.
A.on balance B.out of balance
C.on the balance D.off balance
解析 on balance总的来说。A3.Churches are often built the cross

解析 in the form of...以……样的形式；呈
现……样的形式。B4.When ,metals .
A.heating;extend B.heated;extend
C.heating;expend D.heated;expand
解析 metal和heat为动宾关系，故用heated,
完整形式是：When it is heated,由常识知加
热时铁膨胀，故用一般现在时。D5.They will start their project at
helping the poor children to be educated
in China’s west.
A.aims B.aiming
C.being aimed D.aimed
解析 分析句子知project和aim at之间是主谓
关系，故用其-ing形式aiming。B6.After a long discussion about the
advantages and disadvantages of the plan,
they finally came to a(n) that it
was practical.
A.decision B.opinion
C.conclusion D.impression
解析 come to a conclusion得出结论。空后
的that it was practical是conclusion的同位
语。C of the people on the Net
China’s economy is among the strongest in the world.
A.Four fifth;believes
B.Four fifth;believe
C.Four fifths;believe
D.Four fifths;believes
解析 考查分数表达和主谓一致。当分数中分
子大于1时，分母需用复数，故排除A、B两项；
“分数/百分数+of+名词”作主语时，谓语动词
的单复数取决于名词，本句中people为复数，
故选C。C8.The flight CA9525 for 11∶30 a.m. is
to be put off due to the stormy weather.
A.ordinary B.common
C.formal D.regular
解析 本题考查形容词辨析。regular正常的；
通常的；ordinary普通的，长相一般的；
common常见的；formal正式的。D9.—Any suggestion?
—You’d better the last sentence as
it is rather misleading.
—Sounds reasonable.Then could you a
good ending to it?
A.put out;increase B.leave out;add
C.find out;find D.knock out;choose
解析 leave out此处表示“删除，省略”；
add表示“加上”。根据句意选B项。B10.Mrs. Brown was to have left for
France last week,but something else
delayed him.
A.designed B.able
C.possible D.supposed
解析 be supposed to do...本应该,原来；be
designed to do...打算做……。根据空后的to
have left知D项正确。D11.It was difficult to guess what his
to the news would be.
A.reaction B.opinion
C.comment D.impression
解析 one’s reaction to sth.表某人对……
的反应，此时介词用to。A12.Isn’t rude him to talk to his
mother like that?
A.that;for B.that;of
C.it;for D.it;of
解析 本题考查句式：It is+adj.+of sb.+to
do sth.的否定疑问形式。D13.—Have you got in touch with Tom?
—Oh,sorry.I couldn’t his phone
number at the moment.
A.think about B.think over
C.think out D.think of
解析 此题考查think短语辨析。think about
考虑；think over认真考虑；think out想出；
think of想起；记起。D14.This is a piece of board at the gate of
the construction,which reads：

A.Keep out B.Keep away
C.Keep off D.Keep up
解析 此题考查keep的搭配。keep out留在外
面;keep away （from）远离；keep off（使）
避开；不介入；keep up保持。根据句意“未经
许可，不得入内”。A15.—Bob,are you free at the moment？I have

五、Teaching aids 教具准备
A projector and a recorder.
六、Teaching procedures & ways 教学过程与方式
Step Ⅰ Revision
Check the students’ homework. For Exercises 6 and 7, give them answer sheet. For Exercise 8, ask 10 students to read out the complete sentences one by one. They should pay attention to their pronunciation and intonation.
Step Ⅱ Listening and Writing
This is a continued part to the reading material. The students can get more familiar with some new words and expressions, and also get familiar with the description of an experiment. Ask the students to scan the three activities in LISTENING AND WRITING on P46, so that they know what they are going to do, and try to get ready to catch the key words or key sentences when they are listening.
T: Now, please turn to page 46. We are going to have a listening. At first, scan the three instructions to know what you are going to do.
Several minutes later.
T: Do you know what you are going to do?
Ss: Yes.
T: What’s the first one?
S1: To read the Aim below and predict the Result.
T: What is your prediction?
S1: I think there are two results. One is that the magnesium is heavier than before. The other is that it becomes a little lighter than before. It’s difficult to get a result, unless we make an experiment.
T: Good, this is a correct attitude towards science. Now, we’ll listen to the conversation to find the result. So please listen carefully and write down the key words.
Play the recorder for the students to have a first listening. After that, let the students write down their answers using the key words. If possible, ask them to write the whole sentences.
T: Now let’s listen and complete the description of the scientific experiment. We’ve known the Aim and Result. What we should focus on is Apparatus, Method and Conclusion. And for Method, we should pay attention to the fun_ction words: first, then, next, after that, and lastly. Do you remember?
Ss: Yes.
T: OK, let’s listen again.
Play the tape recorder again. The students listen to the recorder and complete their sentences. At last, collect the answers.
Step Ⅲ Listening and Speaking (P95)
This is another experiment for the students to have a listening. The purpose of the listening is the same as the above one. Ask the students to read the exercises before listening, including Exercises 13, 14 and 15, so that they know clearly what they are going to do.
T: Now, we’ll have another listening. Are you clear about what you are going to do?
Ss: Yes.
T: OK, for Exercise 13, we have to decide what the aim of the experiment is. And then decide the correct order of the stages. So, first look at the pictures, work in pairs to describe what the boy is doing.
Let the students do the job, and then collect their descriptions.
T: Well, just now, I collected some of your descriptions about what the boy is doing. Look at the sentences on the screen.
Write the following sentences on the screen.
a) Bob is writing a conclusion.
b) He is squeezing a lemon.
c) He is going to fire the paper.
d) This is the aim of the experiment.
e) He just lighted a candle.
f) He is going to write something on the paper.
g) He is blowing the paper.
T: All of these descriptions are very good. Now let’s listen to the tape to find the aim and put the stages in the correct order.
After the students finish the task, check their answers with the whole class by listening to the material again.
T: Well, it’s time for us to have a speaking. Look at Exercise 15. Take it in turns to describe the experiment. Use these words and phrases in the box.
Give the students some time to do the job. And then ask one or two of them to read out their descriptions. Teacher can also leave this part as homework.
Step Ⅳ Vocabulary and Speaking
In this part help the students master the rules of reading English numbers. There are 3 tasks in this step: Task 1, Activity 1; Task 2, Activity 2; Task 3, Activities 3 and 4.
Task 1: Activity 1
T: Today we’ll learn how to read some English numbers. Please look at Screen 1, Part A. There are some numbers on it. Find the rules and then work in pairs to read them correctly.
Screen 1:

1,234,567
12,345,678
123,456,789
1,234,567,890
Several minutes later.
T: Do you find the rules of these numbers?
S1: It seems that three zeros are used as a unit.
T: Right. How do you read 20,000?
S1: Twenty thousand.
T: How about 200,000?
S1: Two hundred thousand.
T: How about 2,000,000?
S1: Two thousand thousand.
T: I’m afraid you are wrong. It should be two million.
S1: Sorry, I forget it.
T: OK, how about 20,000,000?
S2: It’s twenty million.
T: Right. How about 200,000,000?
S3: That’s two hundred million.
T: What about 2,000,000,000?
S4: That is two thousand million.
T: Right. This is the way that English numbers are read. American would like to read like this: two billion. You did very well. Sit down, please. Now, let’s look at the screen. Here is the ways we read
English numbers. Please pay attention to the bold face. That’s the unit of the numbers.
Screen 2:
200 Two hundred
2,000 Two thousand
20,000 Twenty thousand
200,000 Two hundred thousand
2,000,000 Two million
20,000,000 Twenty million
200,000,000 Two hundred million
2,000,000,000 Two thousand million or two billion
Let the students read the numbers on Screen 2 and then read numbers in Part B in Screen 1. Let them work in pairs to do the job, and then ask them to read the numbers out individually.
S: ...
T: Now let’s look at Screen 3. These are the ways we read and write the numbers.
Screen 3:
22 Twenty-two
123 One hundred and twenty-three
1,234 One thousand, two hundred and
thirty-four
12,345 Twelve thousand, three hundred
and fifty-five
123,456 One hundred and twenty-three thou-
sand, four hundred and fifty-six
1,234,567 One million, two hundred and thirty
-four thousand, five hundred and
sixty-seven
12,345,678 Twelve million, three hundred and
forty-five thousand, six hundred
and seventy-eight
123,456,789 One hundred and twenty-three mil-
lion, four hundred and fifty-six
thousand, seven hundred and eighty-nine
1,234,567, 890 One billion, two hundred and thirty-
four million, five hundred and sixty-
seven thousand, eight hundred and
ninety
To check whether the students have mastered the way of reading English numbers, let them look at the numbers in Activity 1. There are two mistakes. Let the students read the numbers and find the mistakes.
T: Now there are some numbers in Activity 1 on page 42. There are two mistakes in them. Read the numbers and then find the mistakes. After that I’ll ask some of you to tell the mistakes.
Later.
T: What are the mistakes?
S1: One is in Number 1. The word “thousand” is missing after “four hundred and seventy”. The other is in Number 2. The word “one” (or “a”) is missing before “hundred million”.
T: Quite right. That’s all for Activity 1.
Task 2: Activity 2
Now, let’s turn to Activity 2. Look at the fractions and the way of saying them. What’s the rule?
S1: The upper ones are cardinal numbers and the lower ones are ordinal numbers.
T: Right. When do we use plural forms?
S2: When the upper one is more than one.
T: Right. But the way you are saying is very interesting. In English, what you call “upper one” is called numerator of a fraction; while the “lower one” is called denominator. Now, let’s read these fractions in English: 2/5, 5/8, 9/10, 3/8, 5/6.
Students read the fractions.
Task 3: Activities 3 and 4
T: Now, let’s look at Activity 3. Describe the fractions in Activity 2 as percentages.
Ask the students to work in pairs to compare their answers. And then collect the answers from the class.
T: Now, look at Activity 4. Read these questions aloud and say the answers. Work in pairs to take turns asking and answering the questions.
Give them some help, if some of them have any trouble in doing this. After a while, check the answers with the whole class.
If time permits, finish Activity 5. If not, leave it as homework.
Step Ⅴ Homework
T: In this class we listened to two materials and learned to read some numbers in English. It’s hard, but you have mastered all of them. You are terrific! Now, pay attention to our homework: One is to preview Vocabulary on page 46; The other is to finish Exercise 9 on page 93 and Exercise 15 on page 95. For Exercise 15, you’d better write them down, so that we can show them out on the screen. Next time, I’ll check your answers to these exercises. OK, class is over, see you tomorrow.
Ss: See you.
