1. (由上一步的造句练习，引入3a的学习。)

T: More astronauts should be sent up to discover the secret in space. What else can be done to research the

space?

S₁: More man-made satellites must be sent into space.

S₂: Scientific research should be done carefully.

...

T: Yes, you’ve got good ideas about it. Maybe we can travel to other planets, such as Mars, and even the farther stars. Now we’ll get to know Kangkang’s dream about his uncle’s trip to Mars in 3a.

3. T: Can you say something like this?

Ss: Let’s have a try.

T: OK. First answer my questions in this way.

S₃: The rubbish should be put into the dustbin.

S₄: ...

T: Yeah, very clever. If we want to improve the environment, what should be done?

S₅: More trees must be planted.

S₆: The trees and flowers should be protected well.

S₇: The factories should be built far away from the rivers.

S₈: ...

T: Everybody has great ideas. Can you talk about something else that you’re interested in like what we did just now?

(鼓励学生用情态动词+被动语态的句型来谈论他们感兴趣的话题，如果有人谈到太空航行，就借题发挥进入下一步学习；如果学生没谈到这话题，老师自己说到这一话题。)

Step 5　 Project　 第五步 综合探究活动(时间:10分钟)

2. (1) T: What’s wrong with the watch? What should be done with it?

S: It must be broken. It should be repaired.

(4) T: Why is the woman worried?

S: She is worried about her daughter.

T: What can be done?

S: The girl will be well cared for by her grandmother.

(板书划线部分短语，总结情态动词+被动语态的结构特点。)

1. T: So, let’s do some listening practice.

(放录音，完成2的独立学习。)

T: Listen to the tape carefully, give the right order to the sentences in 2.

(为巩固听力材料中的语言知识，教师可利用提问的方式加深、拓展。)

2. What’s Maria going to do?

(第一个问题较简单，全班一齐回答，不存在问题；但第二个问题需要确认：Maria wants to be a scientist.)

T：Read the conversation again and find out the answers to the questions in 1b. Then I’d like you to ask and answer in pairs.

(给学生三分钟时间准备。)

S₁: Has Maria heard the news about the space flight to Mars?

S₂: No, she hasn’t.

S₃: Who will take part in it?

S₄: The astronauts from China, the United States and Russia.

S₅: Why will the astronauts travel to space?

S₆: They want to discover something new about Mars.

S₇: What is Kangkang going to be when he grows up?

S₈: He wants to be an astronaut.

S₉: Which subject does Maria prefer?

S₁₀: She prefers science to dancing.

T: So what is Maria’s dream?

Ss: She wants to be a scientist in the future.

(学生回答问题的时候，老师记录下对话中的关键词并板书。)

Step 3　 Consolidation　 第三步 巩固(时间：5分钟)

T: That’s wonderful! We all need to work hard. Now please read the dialogs between Kangkang and Maria and then we have to make dialogs between them by ourselves.

(学生分三个步骤进行，先是集体活动，然后二人练习，最后找两到三组准备充分的同学表演对话。)

T: Boys and girls. I’d like you to take part in the dialogs and perform their roles. Boys, you are Kangkang. And girls are Maria. You can use the key words on the blackboard.

Boys: Have you heard the news on the radio about the space flight to Mars?

Girls: No, I haven’t. Who will take part in it?

Boys: ...

Girls: ...

(当学生遇到困难时，教师要及时提醒关键词帮助他们过渡，也可用提问的形式。)

T: OK. Boys are very clever. And girls did well, too. Next, we’ll practice the dialog between Kangkang and Maria in pairs. Take turns to play the both roles.

(学生可以练习两遍。)

T: Who can perform the dialogs in front of the class?

(二组学生表演，可以有比较。)

T: Well done, Group 1. And Group 2 need to work harder.

If you want your dreams to come true, the basic knowledge and skills should be mastered. You did well in speaking English and the listening skill must be improved,too.

Step 4　 Practice　 第四步 练习 (时间：10分钟)

Step 1　 Review　 第一步 复习(时间：10分钟)

　(检查家庭作业，提问关于太空和人类对太空的研究的一些问题。复习，加深对情态动词被动语态的结构、变化及用法巩固，导入一部分新单词。)

T: What movie did Michael and Jane see yesterday?

Ss: They saw a movie about the life in space.

T: Does Michael believe there are aliens?

Ss: No, he doesn’t believe it.

T: And you? Do you believe there are aliens?

Ss: No, I don’t believe it. Because they cannot be seen.

(很有可能出现不同意见，那样更有利于下一步的复习提问。)

T: Do you believe there are aliens?

Ss: Yes, I do.

T: Can they be seen by people?

Ss: ...

T: So more scientific research should be done carefully. What can be done to find out if there are aliens in the space?

S₁: Satellites and spaceships should be sent up.

S₂: Other planets may be visited.

S₃: ...

T: Good idea. If people do more scientific research, I believe more and more unknown things will be discovered in the future.

Now we’re at school to learn the basic knowledge. Work hard, and then we can discover the world in the future.

(板书新单词。)

T: Were you excited about the news of Shenzhou VI?

S₇: I want to be an astronaut.

S₈: I want to be a scientist.
