课题内容

设计思想：

鉴于《新课标》语言技能八级目标对听说读写各方面的要求，语法在英语学习中起着基础的作用。本单元的语法，情态动词的功能及用法，训练学生在各种情景中正确使用情态动词，加强学生在信息交流中对语言符号的感知能力，强调以语言实践为基础的心理感受和强调语法项目在日常生活中的功能。

新课标要求优化学习方式，提高学生自主学习能力。使他们通过观察，体验，探究等积极主动的学习方法，充分发挥自己的学习潜能，提高自主学习能力。并且运用多媒体和信息资源，拓宽学习渠道，形成有个性的学习方法和风格。

教材分析

文章中出现许多进行时的被动语态，如

1.

Sometimes celebrations would be held after hunters had caught animals. 2.

Some festivals are held to honor the dead or to satisfy the ancestors, who might return either to help or do harm.

3.

People should go to clean graves and light incense in memory of their ancestors. 4.

When they can dress up and go to their neighbors’ homes to ask for sweets.

这些句子都是学生自主探究学习的例子。

学情分析: 学生通过初中的学习，已经掌握情态动词的最基本的定义和用法，现在进一步学习情态动词的用法是为了学习其更全面的功能。关键要多练习，了解情态动词是用来表示能力、义务、必须、猜测等说话人的语气或态度的动词。这是学生能正确理解文章句子的关键点。AB层学生要多做运用方面的练习，比如句子翻译；CD层的学生要求能正确理解这一情态动词在语篇中的应用。

教学目标：

1 通过本堂课的学习，所有学生能了解并掌握情态动词的用法和功能。

2 AB层的学生能自己灵活运用所学情态动词。

3 CD层的学生能领悟并翻译出阅读理解中出现的情态动词。

教学重点: 正确理解并运用本单元情态动词

教学难点：

学生如何理解情态动词在阅读理解中的语篇功能，以及情态动词的基本用法。

教学方法:任务型教学法

教学方式：自主探究——要点精析——即时演练——课堂总结

情态动词的特点

1. 情态动词不能单独做谓语, 除ought和have外, 后面只能接不带to的不定式。

2. 情态动词无人称数的变化, 但有些情态动词

如can, will也有一般式和过去式的变化。

3. 情态动词的“时态”形式并不是时间区别的主要标志, 不少情况下, 情态动词的现在式形式和过去式形式都可用来表示现在时间、过去时间和将来时间。

只作情态动词

can / could, may /

might, ought to, must 可情态可实义

need, dare

可情态可助动词

shall / should, will / would 相当于情态动词

have to, used to 3

二、常见情态动词的意义和用法：

1．can和could （ABCD）

1) can的主要用法是：

A. 表示体力或脑力的能力：

e.g. The girl can dance very well.

B. 表示说话的推测、事物的可能性等:

e.g. Can the news be true? C. 在口语中, can可以表示请求或允许: e.g. Can I sit here?

can表示“能够”时与短语be able to同义，但can只用于一般现在时或过去时，而后者可用于各种时态。另外，can表示个人有某种能力，而be able to表示某人通过努力、克服困难做成某事，相当于succeed in doing sth.；叙述过去事实时，最好用was / were able to，因为could只表示过去具有某种能力。

如：

Can you understand the different kinds of English these people are using? Two years later, he was able to speak Chinese very well. 2) could的主要用法是：（ABCD）

A. could是can的过去式, 表示与过去有关的能力和推测:

e.g. We all knew that the young man couldn’t be a doctor. B. could可以代替can表示请求, 但语气较can客气、委婉: e.g. Could you lend me your dictionary?

Could I use your bike? 3) can和could接动词的完成形式，表示可能已经做某事。can用在否定和疑问句中, 表示不相信、怀疑等态度。（ABCD）

e.g. They can’t have gone out because the light is still on. 以could或would提问时，不能再以could或would作答，而应该用can或will。如：

— Could I borrow your dictionary? — Yes, of course you can.

2．may和might 1.may常用来表示：

4

10’

A. 表示请求、允许;比can较为正式: （ABCD）

e.g. May I come in?

You may go now. B. 表示说话人的猜测: “也许”、“可能”: 通常只用于肯定句和否定句中。（ABCD）

e.g. -- I believe the man is from England.

-- But I may be wrong.

The guest may arrive this afternoon.

在肯定句中，may的可能性比can 高，may表示现实的可能性，can表示理论上的可能性。如：

The road may be blocked.

The road can be blocked.

在疑问句中，表示可能性用can。

如：Where can he be?

C. 表示祝愿; 但语气较正式: （AB）

e.g. May you succeed!

May you have a good journey!

2.might的用法有: （ABCD）

多在间接引语中表示过去的可能和允许。

e.g. She said that he might take her bike.

除了在间接引语中以外，might一般不表示过去的可能或者许可。如要表示过去的可能可以用could, 表示过去的许可可以用was (were) allowed to或者had permission to。表示现在的可能，其可能性要比may小。

e.g. She might go home tomorrow. 表示现在的许可, 语气比may较委婉, 一般用于疑问句(包括间接疑问句), 不可用于肯定句或者否定句。

e.g. Might I have a word with you?

3.will和would 1. will是助动词或是情态动词？（ABCD）

will用于构成将来时是助动词。用于表示“意志”“决心”“请求”是情态动词。would亦同理。

e.g. I will tell you something important.（助动词）

Will you tell her that I’m here? （情态动词）

2. 在疑问句中用于第二人称，提出请求或询问。（ABCD）

e.g. If you want help - let me know, will you?

Will you type this, please?

Won’t you sit down?

3. would比will客气委婉。（ABCD）

e.g. Would you help us, please?

I’d go there with you.

5

Teacher wouldn’t allow it.

4．shall和should 1. shall用于构成将来时是助动词。shall用于征求对方的意见，表示“决心”是情态动词。（ABCD）

e.g. Perhaps I shall pay a visit to England this winter. （构成一般将来时, 助动词）

Shall we go by train, Mom? （用于征求对方的意见，情态动词）

I shall go at once. （表“决心”，情态动词）

shall可以用于第一、三人称的疑问句，表示征求意见或许可；还可用于第二、三人称的陈述句中，表示允诺、警告、命令或威胁等。（AB）

e.g. You shall be punished if you break the rule. 2. should表示义务、建议、劝告，意为

“应该”。“should+ have+过去分词”表示本应该在过去做但没有做。（ABCD）

e.g. You should keep your promise.

She should have passed the exam.

5. must和have to 1. must用于一般问句中, 肯定回答用must 否定式用needn’t或don’t have to，做

“不必”, mustn’t表示“禁止，不允许”

（ABCD）

2. 表示“必须”这个意思时，must和

have to稍有区别。must着重说明主观看法，have to强调客观需要。另外，have to能用于更多时态。（ABCD）

e.g. I don’t like this TV set. We must buy a new one.

There was no more bus. They had to walk home. 3. must表示对某人某事的猜测, 作“准是”, “一定”

, 一般用于肯定句中。对过去发生的事情作肯定判断用must have done。（ABCD）

e.g. You must be the new teacher.

He must be joking. There is nobody here. They must have all gone home.

4. must表示“偏要, 硬要”, 指做令人不快的事情。（AB）

e.g. He must come and worry her with question, just when she was busy cooking the dinner. Of course, after I gave her my advice, she must go and do the opposite. 小结：（ABCD）

can / could, may / might, should和

must都可表示肯定的推测。can / could表示客观可能性；may表示推测时，其语气不肯定；might语气更弱，表示6

某事实际发生的可能性；should 表示确定或可能

有的未来或期待；must表示比较肯定的语气。如：

I think advertisements can be quite dangerous.

The newcomer may be dismissed by the company.

The rescue team should arrive by 5 o’clock this

afternoon.

I think the old woman must be a nice person.

could, might, would, should都可表示委婉语气。如:

I wonder if you could let me use your cell phone.

Might I know your telephone number?
