　　Step 1Review 第一步復習(時間:8分鐘)

　　師生討論如何保持健康，引出如何預防流感，導入新課。

　　1. (師生就健康話題進行討論。注意應用情態(tài)動詞should, shouldn’t, must, mustn’t，導入本課的目標語言don’t have to, needn’t。)

　　T: Boys and girls, we know keeping the school and classrooms clean is good for our health. Then do you know how to keep healthy? You’d better say it with should/shouldn’t, must/ mustn’t, had better (not).

　　S1: We should have healthy eating habits.

　　S2: We mustn’t throw litter around.

　　S3: We mustn’t drink sour milk.

　　2. (通過談論如何保持健康，引出如何預防流感這個話題，可適當用漢語解釋，導入新課。)

　　T: Good habits can help us to keep healthy and bad ones can cause diseases. There is a serious disease called flu. It spreads easily among people in spring and autumn.

　　(板書，并要求學生掌握。)

　　T: The flu is a serious disease, but we don’t have to be afraid of it. We can do something to prevent it. But how to prevent it? If you want to answer this question, please follow me.

　　(板書，讓學生猜詞義，并要求掌握。)

　　prevent, question

　　Step 2Presentation 第二步呈現(xiàn)(時間:13分鐘)

　　利用圖片進行師生對話，呈現(xiàn)1a內容，學習文中部分生詞，為聽力掃清障礙。聽錄音回答問題，然后讀對話找關鍵詞，培養(yǎng)學生從聽和閱讀中提取重要信息的能力。

　　1. (假設近幾天發(fā)生流感，教師用圖片給以提示，讓學生盡量用英語談論怎樣來預防流感，學生不會說的單詞，教師給予幫助、引導，以此來學習1a中的部分生詞。)

　　T: Suppose the flu spreads quickly among people these days. What should we do to prevent it?

　　(教師出示開窗通風的圖片。)

　　Ss: We should keep the air fresh.

　　T: Yes, we should keep the air fresh all the time.

　　(教師出示一幅畫有擁擠人群的圖片。)

　　T: If the flu spreads, is it right to go to crowded places?

　　Ss: No, we had better not go to crowded places.(引導學生回答。)

　　T: Yes, we should keep away from crowded places.

　　(板書并要求掌握短語，理解生詞。)

　　crowded, keep away(from)

　　2. (用1a中的圖片引出1a聽力。)

　　T:Look at the picture in 1a. Kangkang is watching TV. On TV, a journalist is interviewing his father. What are they talking about? Let’s listen to1a.

　　(板書，并讓學生理解。)

　　journalist

　　(出示小黑板上的問題，讓學生帶著問題聽1a錄音，回答問題。核對答案。)

　　T: Now, listen to the tape and find out the answers to these questions.

　　(1)What are they talking about?

　　(2)How much advice does Dr. Li give in the dialog?

　　3. (認真閱讀1a，找出關鍵詞及生詞。)

　　T: Please read the dialog carefully and then find out the key words and new words.

　　(核對答案。板書關鍵詞及生詞。解釋并要求學生掌握hurry, hurry up, go ahead；理解finally。)

　　hurry up——on TV——a journalist——ask some questions——go ahead——the flu——spread——among——First, … exercise——Second, keep … clean and … fresh——all the time——Third, wash … and change …——Finally, … crowded places

　　Step 3Consolidation 第三步鞏固(時間:7分鐘)

　　完成1a和1b，使學生熟悉目標語言。

　　1. (再放1a錄音，并讓學生跟讀，注意模仿語音語調。然后完成1b，并以問答形式鞏固。)

　　T: Listen to1aagain and repeat. Pay attention to the pronunciation and intonation. Then finish 1b. Ask and answer in pairs to check Dr. Li’s advice.

　　Example:

　　S1: What should we do to prevent the flu?

　　S2: We should do exercise often. We shouldn’t go to crowded places …

　　2. (學生自讀1a后，四人一組練習對話。然后脫離課本，根據(jù)黑板上的關鍵詞，表演出來。)

　　T: Read1aby yourselves, then practice it in groups of four. You can look at your books at first. Then act out the dialog according to the key words on the blackboard.

　　Step 4Practice 第四步練習(時間:10分鐘)

　　完成1c和2。通過編對話，使學生進一步掌握本課的'目標語言。

　　1. (完成1c，重點訓練don’t have to/ needn’t的用法。練習本課目標語言。)

　　T: Let’s do 1cusing the information in 1b. First read the dialog, and pay attention to the target language don’t have to/needn’t.

　　2. (先師生問答，然后由學生兩人一組練習。)

　　T: Now, I ask, you answer, then practice in pairs.

　　Example:

　　T:Must we finish homework on time?

　　S1: Yes, we must.

　　T:Must we finish it now?

　　S2: No, we don’t have to.

　　S3: No, we needn’t.

　　3. (看2中的圖片，討論怎樣預防流感。)

　　T: Look at the pictures in 2, and discuss what we should do to prevent the flu.

　　(討論幾分鐘后，要求學生完成2里面的練習。提示學生注意should, had better, must的用法。)

　　Example:

　　Dialog 1

　　(學生小組練習之后，核對答案。教師可以請幾組同學到講臺前為大家表演。)

　　Step 5Project 第五步綜合探究活動(時間:7分鐘)

　　通過創(chuàng)設情景，分角色表演和寫短文，提高學生綜合運用本課所學語言知識的能力。

　　1. (四人一組做一個采訪。一人扮演記者，其他三人扮演醫(yī)生。記者采訪如何預防流感，醫(yī)生回答記者的提問。評出優(yōu)勝組。)

　　T: Work in groups of four. One acts as a journalist. The others act as doctors. The journalist asks how to prevent the flu. The doctors answer the journalist’s questions. Then act out in the front and we will decide which group is the winner at last.

　　2. Homework:
