1.教材分析 本单元以“健康饮食”为中心话题，通过单元教学让学生了解各种食物对人体的作用，引导学生关注平衡膳食，促使学生养成健康饮食的习惯。针对现实中遇到的实际问题发表自己的看法。最后让学生运用所学知识，两人一组研究中餐，设计食谱。 1.1 WARMINGUP是本单元一个重要的组成部分。让学生看图讨论不同食物对人体的作用，了解饮食与人体健康的关系。通过几个设问激发学生思考自己的饮食习惯是否合理，运用已有的知识经验思考什么是HealthyEating. 1.2 PREREADING通过一个表格和一个排序题引导学生对比不同食物中哪些食物富含脂肪、纤维素、维生素和糖份。可添加讨论如何在烹饪中保持食物营养，从而有利于健康。 1.3 READING讲述王鹏和咏慧开饭店的不同风格和顾客对不同食品的反应，反映了现代人对饮食的关注和对时尚的追求。但王鹏和咏慧都没有提供平衡的膳食，经过一段时间的磨合，他们决定合作，提供既有能量又有纤维的食品。戏剧性的结尾增添了故事的趣味性。通过阅读丰富学生的饮食文化，教会他们如何改善饮食习惯；在现实生活中碰到麻烦时，如何正确处理矛盾，解决问题。 1.4 PREHENING利用判断和回答问题的形式考查学生对课文细节的理解，对比两家饭店所提供膳食的优缺点。 1.5 LEARNINGABOUTLANGUAGE是继prehending之后的又一指导性练习。注重考查词性的变化，课文中重点词汇在语篇中的熟练运用及情态动词的不同功能，并设计连线和情景对话两个题型予以巩固。 1.6 USINGLANGUAGE体现了学以致用的目的，从Listening,Reading,Speaking,Writing四方面训练学生，完成语言的输入性学习和输出性训练的过程，结合生活实际，让学生两人一组研究中餐设计食谱。 2．教材重组2.1精读把Warmingup作为Reading的导入部分，把Prereading、Reading和prehending整合在一起作为一堂“精读课”。2.2知识点学习把Reading的知识上一节“知识课”。2.3.语言学习把LearningAboutLanguage上一节“练习课”。2.4语法学习把Discoveringusefulstructures上一节“语法课”。 2.5听力和阅读UsingLanguage的Listening和Reading上一堂“听力课加泛读课”。 2.6口语和写作将UsingLanguage的Speaking和Writing上一堂“写作课”。 3．课型设计与课时分配 1stperiodWarmingupandReading 2ndperiodLanguagepoints 3rdperiodUsingLanguage

1）表示主观的义务和必要,

主要用于肯定句和疑问句,

意思为

“必须……，得……，要……”；由must引起的疑问句，肯定回答要用must或have

to,

否定回答要用needn’t或don’t

have

to,

意思是“不必”；must的否定形式mustn’t表示禁止，意思是“不能，不许”。如：

—Must

I

finish

the

task

right

now?

我现在必须完成这个工作吗？—Yes,

you

must.

/

Yes,

you

have

to.

是的。

(—No,youneedn’t./No,youdon’thaveto.不，不必。)Youmustn’teherewithoutpermission.未经允许，你不能来这儿。have

to

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：

Ihavetoattendanimportantmeetingthisafternoon.今天下午我不得不参加一个重要的会议。Motherisout,soIhavetolookaftertheshop.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’thaveto,相当于needn’t。如：Theydon’thavetobuyaputeratpresent.

他们目前没有必要买电脑。
