Section B教学设计3
教学目标：
1、复习情态动词can表示许可的用法；
2、复习练习运用祈使句以及情态动词have to及must来表达一些规则。

3、谈论表达自己对规则的想法或看法。

教学重点：
1、根据所提供的文字资料来表达自己对一些规则的看法。

2、能用所学的语言知识来写出自己在家中或在学校中的一些规则。

教学难点：
写一封信来谈论一下自己应遵守的一些规则，并表达自己对这些规则的看法。

教学用具：
课件、录音机和单词图片
教学过程：
Step 1 Warming- up and revision
1. Have a dictation of the new words and expressions.
2. Let Ss read the letters.
3. Check the use of have to and must
Step 2 Presentation
1. Present some new words on the big screen.
hair, learn, keep + 名词+ 形容词
2. Ss learn the new words and expressions.
3. Review the how to use have to and must; can and can't.
Step 3 Reading
1. Read the letter again and complete the sentences with have to/ must, can or can't.
2. 提示：have to与must的用法：
1）must表示一种主观的需要，而have to表示一种客观的需要，意思是“不得不”。

如：
I have to attend an important meeting this afternoon.
今天下午我不得不参加一个重要的会议。

Mother is out, so I have to look after the shop.
妈妈不在家，因此我不得不照看商店。

2）have to的否定形式是don’t have to, 相当于needn’t。

如：
They don’t have to buy a computer at present.
他们目前没有必要买电脑。

3. 阅读指导：
1) 首先，认真阅读2c中的这些句子，明白它们所谈论的相关规则。

2）带着相关规则再去读2a中的信，在与之相关的内容处认真分析，理解规则的真正含义，并填上正确的词汇。

3）再次阅读这些句子一遍，看是否通顺。

4. Check the answers.
Step 4 Practice
1. T: Zhao Pei has many rules at home and at school. She's unhappy, too. She wants some help from Dr. Know. Read her letter below and fill in the blanks with have to /must, can /can't.
2. 指导：首先，认真阅读整篇短文，理解短文的大意。

然后，认真阅读每个句子，理解作者的对这些规则的看法；同时，推敲每个句子深处的意思，确定是用have to/must还是
can/can't。

最后，应再通读一遍短文，看自己所填写的词组是否通顺正确。

3. Check the answers.
Step 5 Writing
1. Let's work on 3b:
We have many rules at home and at our school. Think what things you have to do and what things you can't do. Complete the chart with rules in your home and school. You can discuss with your partners in your group.
2. Ss discuss their rules in groups. Then fill in the blanks. Then check the rules you think are unfair.
For example: You must wear a school uniform at school. You must keep your hair short at school.
3. Let some groups say their answers. Write some of the rules on the blackboard.
4. Now write a letter to Dr Know. Tell her about all the rules and how you feel about them.
5. 写作指导：
首先，可以再次阅读2b及3a中的短信的内容及格式。

其次，模仿这两封信的格式写好自己信件的格式；然后，根据刚才自己小组讨论的规则整理成一封文字通顺的信件。

并且，表达自己对这些规则的想法或看法。
