    1. Introduce students to such as as an alternative way of including examples in a sentence. When we use for example, we must have already defined what we are talking about. Such as can be used in the same way, but sometimes it can be the part of the definition.
    2. Such as must be placed directly next to the words it refers to, and it must be followed by a noun or nouns. Unlike for example, such as cannot be followed by a finite clause.

    1.This exercise gives students practice in two skills: selecting the relevant information from a dialogue, and filling in a form correctly.
    2.As usual. Explain the situation clearly. Students must act the role of the man, and write down the information. Explain any difficult words. Play the recording twice.
    3.Check their answers.
    4.Teach the new words: Screen filter contact reference no quantity post-task activity (10’)work in pairs and then role-play the dialogue assignment daily topic: computers教后感：怎么样向孩子们呈现最好的老师形象，怎么样让他们喜欢我而且喜欢上英语，怎么样让我的班级的孩子们英语个个学得棒棒的。课堂是主渠道。  Period 6 Teaching aims: Language focus objective:Learn to compare two things and more than two things procedure objective:listening, note-taking, speaking materials: Students book 9ACassette 9A and a cassette playerMultimedia equipment Time allocation:  40 minutes Teaching key points and difficulties:The use of comparative degree and superlative degree Suggested teaching procedure: Pre-task activity: (10’)Daily topic: computers II. while-task activity: (20’) A  Comparing two things
    1.Draw some dissimilar pairs of lines, shapes or simple objects on the board and ask the class to tell you the differences between them. They should be able to make short sentences telling you.
    2.Read the introduction to the class. Ask students to give you examples of things which are cheaper, higher, and more useful than the others.
    3.Point out that, usually, one-syllable adj take the -er ending. Two-syllable words can use either the -er ending or the more construction, but longer adj always use more. Many two-syllable adj are almost found the -er form.
    Lucky-luckier  funny-funnier  quiet-quieter   clever-cleverer
    4.Ask students to do Ex A1 on their own.
    5.Tell students to do Ex A2 and A3 with their partners.
    B  Comparing more than two things.
    1 Read the introduction with the class. Note that the rules for the formation of superlative adjectives are similar to those for the formation of comparative adjectives. The -er ending of the comparative adjective is replaced by the -est ending of the superlative, and more is replaced by the most. Irregular forms are considered on page 27.
    2 Tell students to do Exercises B1 and B2 on their own.
    3 Do Exercises B3 with the class, telling the students to follow the given instructions.
    4 Stress to the class the need to use the article the. There can only be one ocean that is the biggest, so there is definite reference, and the definite article must be used.
    C  Using good, bad and far
    Read the introduction with the class. Ask students to do Exercises C1 and C3 on their own, and to do Exercises C2 with their partners.
    Notes:
    1 Further and furthest have the same meaning as farther and farthest, except that further has the additional meaning of extra/ more (e.g., The doctor will tell you if there are any further developments.).
    2 The adjective ill is not usually used in the comparative or superlative forms. We use worse and worst instead.
 III. post-task activity: (10’)Finish the part of the grammar book IV. assignment:Finish the rest of the grammar book 教后感：这节课的语法内容是形容词的比较级和最高级，我在讲解时虽然比较细致，口头练习也比较到位。  Period 7Teaching aims: Language focus objective:Learn to give opinions, agreeing and disagreeingWrite a letter  procedure objective:listening, note-taking, speaking and writing materials: Students book 9ACassette 9A and a cassette playerMultimedia equipment Time allocation:  40 minutes Teaching key points and difficulties:give opinions, agreeing and disagreeing  Suggested teaching procedure: Pre-task activity: (10’)Comments on assignment II. while-task activity: (20’) Speaking
    A  Talk time
    Giving opinions, agreeing and disagreeing
    1 This section continues to practice the comparative and superlative forms and helps students to take part in conversations expressing opinions.
    2 Linguists often use the concept of maintaining face to explain many language structures. If someone disagrees with you but does not wish to offend you, they must use language forms that soften any threat to you. When we say something that pleases someone, such as agreeing with them, we can be much more straightforward.
    3 Read the examples in the Student's Book, and then point out the following additional expressions of agreement.
    Yes, indeed.
    Yes, (that's) exactly what I think.
    I agree totally/ 100%/ completely.
    That's just what I was going to say.
    I think so, too.
    Yes, that's right.
    How true!
    4 Expressing disagreement is sometimes more of a problem. Here students are taught a very bare form, suitable to their level. Certainly, a direct form such as I don't agree should be spoken with some hesitation in the voice.
     5 Adverbs are often used to weaken the force of the disagreement (e.g., I don't really agree; I don't altogether agree.). Point out these other forms of disagreements.
    I'm not so sure about that.
    Do you really think so?
    I'm a bit surprised you say that.
    Well, that's a matter of opinion.
    I wouldn't say that.
    6 Do ExA1. Read the dialogue to the class and tell them to practise it. Then ask one or two pairs of students to perform it.
    7 Do Ex A2 and A3. B Speak up
    1 This activity requires students to prepare and carry out a simple survey in English. It also allows them to have some variety in the task. It is not essential for of them to have the same survey questions.
    2 Let students work in pairs or in groups of three to produce eight questions on this topic. If possible, check their questions (mainly to make sure they make sense) before the next stage.
    Sample questions are given below but students are free to have difference questions.
    3 If time permits, let some students report back to the class. They cam this by simply reading out their questions and summarizing some of the results.

    Asking 'Yes', 'No' questions
    This is a familiar game which is sometimes called 'Twenty Questions'. The game practices the skill of forming questions in English, which most students find difficult. However, this is an important skill in both life and exam. This game also develops logical thinking. In this variation, students must imagine that they are a famous person or a character.

    Sample questions:
    Are you alive/dead/real/fictional?
    Were you in books/songs/films/poems?
    Do/Did you live in Europe/Asia/China?
    Did you live hundreds/thousands of years ago？
    Did you live in the 18th/21st century?
    Did you write books/paint pictures/fight battles?
    Are you a film star/singer/politician/sportsman/woman?
    Have you ever been in a film/visited China?
    Are you a cartoon character/character in a legend?

    Using English Abbreviations
1.Abbreviations are useful in note-taking, as well as being items that the students will see frequently. Ask the class to do Exercise A.
Writing
2.This exercise gives further practice in using the comparative form of adjectives in a context analyzed task. It also practices information-transfer skills. Ask students to work individually to complete the two exercises.  III. post-task activity: (10’)Additional activity:Ask students to write a few sentences comparing:        their primary school and their secondary school;        Shanghai and Beijing;        Trains and buses. IV. assignment:  write a short passage with a few sentences comparing   Period8-9Exercises and test for chapter 2 教后感：让学生将所学知识运用到自己的生活中，学会give opinions, agreeing and disagreeing.
