教学反思
多媒体能使整个教学过程表现为声、图、文并茂，使声音、图像、文字的呈现更自然。为此，在课堂上，教师应该为学生创造学习氛围，让学生时常有成功感和成就感，以便进一步激发学生学习的内在动力。在本堂课中应注意让发音较标准的同学多朗读，让思维敏捷的同学先回答问题，让善于观察的同学多纠正错误，让反应慢的同学多回答低难度问题。尽量使每个同学多动脑、多动口、多动手。

Step 1 Greetings

Step 2 A Game
Show a list of chores on the blackboard：
do the dishes clean your room
take out the trash? sweep the floor
fold your clothes make your bed
Give them a set of blank cards.
T：Let’s play a game. You will work in groups of four. First each group writes the chores on the cards. Put them face down. The first student turns over a card，and asks the student next to him/her to do this chore. That student says “no” and gives a reason. Each student should give a reason that has not been given before. The one who can’t give a proper reason will be out of the game. Those who can keep coming up with reasons will be the winner.
Step 3 Role play
Ask some pairs to role play the dialogue in 2d.
Step 4 Presentation
Say：As we all know，Mother does almost all the housework in the house. She is always tired. Should we help Mother? What we can do to help her? Ask some students to report their answers.
Step 5 Reading
Say：Now let’s read an article about Nancy and her mother. Please read quickly and answer the questions：1. Why was Nancy’s mom angry with her? 2. Did they solve the problem? How?
Then ask some students to report their answers.
Now let’s read the sentences in 3b，try to understand and translate them. Then read the passage again carefully and try to underline the sentences from the reading that mean the same thing. After several minutes， ask some students to report their answers and translate the sentences into Chinese.
Step 6 Language points
1. You watch TV all the time and ...
all the time（在该段时间内）一直；向来，一向；时时刻刻；每时每刻
e.g. I do this all the time. 我一直是这么做的。
This happens all the time. 这种情况是时时发生的。
2. I’m just as tired as you are!
as ... as 意为 “和…一样”，表示同级的比较。使用时要注意第一个as为副词，第二个as为连词。其基本结构为：as +?adj./?adv.?+ as。
e.g. This?film?is?as?interesting?as?that?one. 这部电影和那部电影一样有趣。
Your?pen?writes?as?smoothly?as?mine. 你的钢笔书写起来和我的一样流畅。
注意：as … as 的否定形式为“not as/so + adj./adv. + as”。
e.g. He didn’t act as well as you. 他表现得不如你好。
3. For one week，she did not do any housework， and neither did I.
1) neither 用作副词，作“也不”解释，放在句首，表示前面否定的内容也适用于另一个人或物，句子须采用部分倒装。此时也可用nor替换 neither 使用。
e.g. --- I?don’t?like?this?dress.?我不喜欢这件连衣裙。
--- Neither?/?Nor?do?I.?我也不喜欢。
注意：neither 之后的主语要置于助动词或系动词之后。
2) neither 用作代词，表示“两者都不，双方均不”。
He?answered?neither?of?the?letters.?他两封信都没回。
e.g.--- Which?one?would?you?like??你喜欢哪一个？
--- Neither. 两个都不喜欢。?
Step 7 Practice
3c, Show the sentences on the screen： 1. Could you take the dog for a walk? 2. I walked home from school. Then ask some students to read and translate them. Then help them to say that the word “walk” in the first sentence is a noun and the word “walked” in the second sentence is a verb. Then ask the students to look at the sentences in 3c and decide whether the underlined words in the sentences are verbs or nouns. Then write another sentence using the underlined word in the other form. Finally ask some students to report their answers.
Step 8 Grammar focus
Ask the students to translate the sentences in the box and try to remember them. Then practice them in pairs. Finally ask the students to make up more similar dialogues.
Step 9 Practice
4a First ask the students to translate the sentences from 1 to 5，then decide whether they are requests or permissions. Then match each one with the correct response. Finally ask the students to practice the dialogues in pairs.
4b First ask the students to fill in the blanks in the conversation by themselves and then ask them to check the answers in pairs. Finally ask them to practice the dialogue in pairs.
Step 10 Group work
Say：Boys and girls，we’ll go for a camping trip tomorrow. And today we should prepare what we need. Please work in groups and make a list of things your group needs to do for a camping trip. Then discuss who will do them and complete the chart in 4c. You can use the dialogue to help you：A：Could you please bring a tent， Liu Chang? B：Sure. And could you please…? C：Sorry，I can’t. I have to… After several minutes，ask some groups to practice the dialogue.

教学反思
一节课下来，大部分学生都能积极投入到课堂教学中来，并积极举手发言。课堂气氛比较活跃，调动了大部分学生听课的积极性，因此合作教学对提高学生实际的语言交流能力以及与他人的合作能力有很大的促进作用。但很明显，语言表达能力强的学生参与的机会相对要多，代表小组汇报的机会也多，而另有一些学生却习惯于当听众，被动地接受别人的观点，很少发表自己的个人意见，也就是说在小组合作学习中学生的参与度不均衡，而这部分学生主要是学习困难生。?????????????????????

教学反思
教师在开展教学活动时，个别小组出现“冷清”的场面，这些学生只顾自己独立思考，停留在独立学习的层次上，没有发挥合作学习的优势，使合作流于形式。出现上述情况，从合作学习的参与者——教师的角度分析主要是教师的设计和引导不恰当、或小组的编排不够合理等。从合作学习的参与者——学生的角度分析，主要是学生还没有掌握基本的合作技能，或者合作意识淡薄，角色的落实不到位，或合作能力不强，合作精神不够。因此作为教师既要注意到每个合作小组成员的合理编排，又要注意到自己教学内容的设计、话题的趣味性以及如何把学生的积极性真正调动起来。

Sample list：sweep the floor，clean the window，brush the wall，move the plants，take care of the pets
Now imagine you are going to move to a new house. You need some help from a friend. Write an e-mail message and ask him or her for help.
教学反思
写作能力的培养不是一朝一夕的事，必须坚持练习，尽量每节课都能让学生写点儿什么，不要都推到最后，这样学生会感到太难，不敢动笔写。本课在3b环节练习写作后，趁热打铁，在课堂作业部分又让学生写了一封信，用上本单元的重点词汇、短语和句型，有了前几节课的学习和巩固，学生们写起来得心应手。
