Ⅲ. 教材分析与教材重组

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。

LEARNING ABOUT LANGUAGE 是继Comprehending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。

教材重组

2.1 语言学习

把Learning About Language和Workbook中的Using words and expressions, Using Structures结合在一起上一节“语法课”。

LEARNING ABOUT LANGUAGE

-Grammar

Teaching Goals:

1. To enable Ss to master some new words and expressions. 2. To get Ss to have knowledge of this grammar point: ought to

Teaching Procedures: Step 1. Revision

1. Review the new words of this part. 2. Ask some of the students to retell the text. Step 2 Grammar

Explain for Ss the grammar point. ought是情态动词，与to 连接构成情态动词词组。

ought无人称和时态变化，可用于现在时以及将来时，用于过去时则位于动词过去式之后或不定式的完成式之前。ought 可以表示“义务”、“要求”或“劝告”，常译作“应该”、“应当”等（和should 差不多，只是语气稍差一些）；有时表示“非常可能”的意思，否定式为ought not to（oughtn’t to），疑问句式为Ought I / you to …… ？。

I ought to write to him today／tomorrow．

我今天／明天应该给他写封信。

I knew I ought to write to him．

我那时知道我应该给他写封信。

She said I ought to write．

她说我应该写。

I know／knew that I ought to have written．

我知道／那时知道我该写的。

ought与带to的不定式连用。为了提醒学生这一点，常称之为ought to。

问句或话语中用ought to的时候，可以用

should来回答；用should的问句或话语也可以用ought to回答：

—You ought to put in central heating．

—Yes，I suppose I should．

—你应该装上暖气。

—是的，我应该装。

1. ought to／should should 和ought to 都为“应该”的意思，可用于各种人称。ought to 的语气稍重一些。

You ought to (should) follow your teacher’s advice.

表示主语的义务或责任：

You should take care of your sister．

你应当去照顾你妹妹。

They shouldn't allow parking here；the street is too narrow．

这儿不该允许停车；马路太窄了。

should 和ought to 后面跟动词不定式的完成式,其肯定句表示”过去应该做而未做”, 其否定句则表示”过去不该做但做了”。

You should/ought to have made the decision a week ago. I shouldn't have made such a foolish mistake.

多数情况下，ought to 可与should互换使用。ought to的反意疑问句用shouldn’t替代。

2. must和have to must的用法

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, you needn’t. / No, you don’t

have to. 不，不必。)

You mustn’t come here without permission.

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： 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。 2. Ask Ss to read the text again and pay attention to the modal verbs and then finish Ex1,2,3. Step 5. Homework 1.

Ask Ss to review what has been learned in this period. 2.

Ask Ss to act out the dialogue of Ex2 of Discovering Useful Structures on P13.
