Teaching procedures & ways 教学过程与方式 Step Ⅰ Revision
For the homework, check whether they can read the decimals correctly by following the examples. If they have any problems about this part, help them. For Exercise 15, ask some students to read out their descriptions. Meanwhile, pay attention to whether they have used the function words and expressions in the table. Step Ⅱ Lead-in
Show some proverbs to the students and let them guess the meanings of the sentences. And then give them the correct meanings of the sentences.
T: Today, we’ll learn the degrees of comparison. At first, let’s look at the screen and guess the meanings of the sentences. 1. Two heads are better than one. 2. More haste, less speed. 3. East, west, home is best. 4. The best mirror is an old friend. 5. Least talk, most work.
Students give their answers. And teacher corrects some mistakes if there are any. Sample translations: 1.(谚) 两人智慧胜一人。 2.(谚) 欲速则不达。 3.东跑西跑还是家里最好。 4.(谚)老友是宝镜。 5.少说话，多干事。
T: From these sentences, we know that Degrees of Comparison are used widely in English. Today, we’ll learn some of them. Step Ⅲ Degrees of comparison 1 (P43)
In this step, the students will finish Activity 1 and Activity 2 on page 43. Task 1: Activity 1
Let the students give some sentences that they have learned with the comparative degree in. And then turn to page 43 and read the first two sentences in Activity 1. Ask

them to tell the difference between these sentences.
T: Can you give me some sentences with the comparative degree in them? S1: The earth is larger than the moon. S2: Tom is fatter than Mike.
S3: She is more beautiful than her sister.
T: Right. What’s the difference between these sentences and the one on the blackboard?
Write the sentence on the blackboard:
The earth is forty-nine times larger than the moon.
S4: There are “forty-nine” times before the word “larger”.
T: Right. That’s what we’ll learn today. When we want to express degrees of comparison, we can use this structure.
A is ... times larger (bigger, taller, higher, wider, longer etc.) than B. Write down the structure on the blackboard.
T: It’s very simple; just add “... times” before the comparative degree. But please note that we say “twice” instead of “two times”. Are you clear? Ss: Yes.
T: Now, let’s do some easy maths problems. Listen! If Object A is 10 meters long, and Object B is twice longer than Object A, how long is Object B? S5: Twenty meters long.
T: Good. You’ve understood the structure correctly. The second problem: if Object A weighs 100 kilogrammes, and Object B is four times heavier, how heavy is Object B? S6: 400 kilogrammes. T: Why?
S6: Because Object B is four times heavier than Object A.
T: OK. Besides this structure, we can use another structure to express the same meaning. That is:
A is ... times as large (big, tall, long etc.) as B. Write down the structure on the blackboard. T: Well, let’s go on to do some maths problems.

Task 2: Activity 2
Read the instruction of Activity 2, and let the students read the sentences in Example. After that, ask them to finish the following 5 problems.
T: The purpose of the task is not to check your intelligence, because I believe that all of you have high IQ. It’s about the uses of the two structures we’ve just learnt. Now, finish the task and then check your answers with your partners. Remember you must use both of the structures to practice what we’ve just learned.
After a while, ask four students to read out their answers in complete sentences. S1: I think winter in Harbin is four times colder than Beijing. Or, winter in Harbin is four times as cold as Beijing.
T: The structure is right, but there are mistakes in the two sentences. Who can correct the mistakes and read out a complete sentence?
S2: It should be “Winter in Harbin is four times colder than that in Beijing.”
T: Right. When we are using the comparative degree，we must pay attention to the two comparison objects. Now who would like to do the third one?
S3: Miss Wu, can we say that “in winter the temperature of Harbin is four times lower than in Beijing”?
T: That’s a good sentence, but also you should pay attention to the two comparison objects. We should say that “In winter the temperature of Harbin is four times lower than that of Beijing.”
Write down the two sentences on the blackboard, so that the students can clearly know the agreement in two comparison objects. T: Are you clear? OK, how about the third problem?
S4: I think Mount Qumolangma is about six times higher than Mount Tai. Or, Mount Qumolangma is about six times as high as Mount Tai.
S5: My aunt’s house is twice as large as my house. Or, my aunt’s house is twice larger than my house.
S6: Tom weighs over twice as heavy as Lily. Or, Tom is over twice heavier than Lily. Step Ⅳ Degrees of comparison 2 (P47) Task 1: Activity 1
