16、准备A computer, a projector and a recorder.Teaching procedures 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 Zhou Flight. What kind of materi
17、als would you like to use?S1: Id like to use some materials that are light enough and hard enough, so that the flight can be easily sent up into space, and doesnt get in trouble.T: How can we find such kind of materials?S2: We can do some experiments. We cant use natural materials only; we need both
18、 man-made and natural materials.T: Thats right. Now well read a passage about a scientific experiment. Please turn to page 44. Well go through Passage A. When we are doing a thing, we should do it in an orderly way. Its especially true with a scientific experiment. Now lets see the four words in the
19、 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
20、: Right. “Aim” means purpose or object. For example, he has only one aim in life, that is, to be a millionaire. And for “conclusion”, lets see an example first, when you have worked on a maths problem for a long time, but you still cant work it out. So you may make a conclusion that the problem is w
21、rong. 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
22、?Ss: It should be aim, method, result and conclusion.T: Thats right. Without aim, we dont know where to go; without method, we dont know how to do things well; without result, well draw a blank or gain nothing; without conclusion, well find what weve done is worth nothing. Task 2: Activity 2Ask the
23、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, whats the best title for the passag
24、e?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, lets l
25、ook at Activity 3.Task 3: Activity 3Ask 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 Reading (Passage B: P45)In this part, the students will read the passage and then fill in the table bel
26、ow 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 passageT: Now, well continue to read Passage B.
27、 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
28、 Simple Scientific Experiment: Introduction Aim Apparatus Method Result ConclusionT: 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, an
29、d 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 whats “Bunsen burner”? We often find it in labs
30、. Now, turn to page 46, and find the picture of Bunsen burner.Task 2: Activity 5T: 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
31、whole class.Task 3: Activity 6This 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 waterOil: liquid whic

It is important to know how they react with different substances, for example, waterand oxygen. 3. This makes sure there is no air in the water. T: Before we finish
35、 this class, lets 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
36、lets 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.

After class, please do Exercises 6, 7 and 8 on pages 92 Task 2, Activity 2; Task 3, Activities 3 and 4.Task 1: Activity 1T
39、: Today well 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:A220B1222002,00020,000200,0002,000,00020,000,000200,000,0002,000,000,0001231,23412,345123,4561,234,56712,345,67812
40、3,456,7891,234,567,890Several 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: Im afraid you
41、are wrong. It should be two million.S1: Sorry, I forget it.T: OK, how about 20,000,000?S2: Its twenty million.T: Right. How about 200,000,000?S3: Thats 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
42、would like to read like this: two billion. You did very well. Sit down, please. Now, lets look at the screen. Here is the ways we read English numbers. Please pay attention to the bold face. Thats the unit of the numbers.Screen 2:200 Two hundred2,000 Two thousand20,000 Twenty thousand200,000 Two hun

These are the ways we read and write the numbers.Screen 3:22 Twenty-two123 One hundred and twenty-three1,234 One thousand, two hundred andthirty-four12,345 Twelve thousand, three hundredand fifty-five123,456 One hundred and twenty-three thou-s

46、even hundred and eighty-nine1,234,567, 890 One billion, two hundred and thirty-four million, five hundred and sixty-seven thousand, eight hundred andninetyTo check whether the students have mastered the way of reading English numbers, let them look at the numbers in Activity 1. There are two mistake
47、s. 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 Ill ask some of you to tell the mistakes.Later.T: What are the mistakes?S1: One is in Number 1. T
48、he 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. Thats all for Activity 1. Task 2: Activity 2Now, lets turn to Activity 2. Look at the fractions and the way of saying them. Whats the
49、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, lets read these fractions in English: 2/5, 5/8, 9/10, 3/8, 5/6.Students read the fractions.Task 3: Activities 3 and 4T: Now, lets look at Activity 3. Descri
