一、学生分析

由于我们班男学生比较多，有一部分来自农村学校，英语底子比较差，就产生了厌学情绪，甚至想放弃英语的学习，他们最大的问题就是老是认为语法听不懂，认为语法太多太杂，不容易掌握。我们这个单元正好讲的是交通堵塞，交通堵塞问题是一个世界性的问题，如何解决交通堵塞问题成为世界各国关心的热点，这需要我们每个人都做出努力，学生就应该充分的了解什么可以做，什么不可以做，这就需要他们了解英语的路标是怎样写的，用的大多是祈使句。在课堂教学中，通过一些句子的使用，让他们了解到祈使句的实用性，从而激发他们学习语法的热情。

二、教材分析

本單元以交通堵塞为话题，以词汇为主线，从听说读写各方面围绕交通这个社会热点问题对学生进行语言训练。通过本模块的学习，学生不仅能够掌握与交通有关的词汇还可以就有关交通方面的问题提出建议，为治理交通堵塞的问题献计献策，尽自己一点微薄的力量。

三、教学过程

Step1： Go over the words and phrases to give advice. Do the exercise3 on page73. 从而使学生为学习祈使句奠定点基础。

Step2；Show some road signs to the students and ask them what they should do .

For example： （1）Turn right；（2）Dont go faster than 90 kph；（3）Dont turn left；（4）Stop；（5）be careful .

最后给出总结，we use imperatives for different reasons，such as telling people what to do，giving instructions and advice，making recommendations and suggestions，and for making offers.

For example： 1 come in and sit down，please.

2 Dont open the window—its cold.

3 Shut up.

4 Dont speak up.

5 Wear more clothes---its too cold.

6 Drink a little water.

Ask the students to notice that the affirmative form of the imperative is the infinitive with to. The nagative imperative uses dont and the infinitive.

Emphatic imperative

Step2 Tell the students We can make an emphatic imperative with do +imperative. This is common in polite requests，complains and apologies.

1 Do study hard.

2 Do come early tomorrow.

3 Do be careful.

4 Do behave yourself.

Do（nt） be

Although do is not normally used an anxiliary with be，do is used before be in negative and emphatic imperatives.

1 Dont be nervou.

2 Be brave.

3 Be serious.

Always and never come before imperatives

Always remember what I told you.

Never speak to the old like that.

Subject with imperative

Tell the students the imperative does not usually have a subject，but we can use a noun or pronoun to make it clear who we are speaking to.

1 John come here.

2 Everybody help yourselves.

3 Relax all of you.

You before an imperative an suggest emphatic persuation or anger.

1 You be quiet and go to bed.

2 You put on your clothes.

Question tags

After imperatives，the normal question tags are will you？/wont you？/would you？/can you？/could you？/could you？ After negative imperatives，“will you” is used.

1 Sit down，will you？

2 Ring me up. Wont you？

5 Dont move，will you？
