一、學生分析

由于我們班男學生比較多，有一部分來自農村學校，英語底子比較差，就產生了厭學情緒，甚至想放棄英語的學習，他們最大的問題就是老是認為語法聽不懂，認為語法太多太雜，不容易掌握。我們這個單元正好講的是交通堵塞，交通堵塞問題是一個世界性的問題，如何解決交通堵塞問題成為世界各國關心的熱點，這需要我們每個人都做出努力，學生就應該充分的了解什么可以做，什么不可以做，這就需要他們了解英語的路標是怎樣寫的，用的大多是祈使句。在課堂教學中，通過一些句子的使用，讓他們了解到祈使句的實用性，從而激發(fā)他們學習語法的熱情。

二、教材分析

本單元以交通堵塞為話題，以詞匯為主線，從聽說讀寫各方面圍繞交通這個社會熱點問題對學生進行語言訓練。通過本模塊的學習，學生不僅能夠掌握與交通有關的詞匯還可以就有關交通方面的問題提出建議，為治理交通堵塞的問題獻計獻策，盡自己一點微薄的力量。

三、教學過程

Step1： Go over the words and phrases to give advice. Do the exercise3 on page73. 從而使學生為學習祈使句奠定點基礎。

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 .

最后給出總結，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？
