1. Teach students the solar system, then ask them to look at the picture of the solar system on the blackboard. Tell them to put the nine planets at the right place.(制作九大行星的教具)

(设计说明：通过这个游戏活动，将较难掌握的天体名称以生动有趣的形式呈现给学生，可以活跃课堂气氛，提高学生的兴趣。学生在愉悦的氛围中学习知识，能达到良好的教学效果。)

3. Making a report

Students make a short report with the questionnaire.

(设计说明：这一环节是一个热身活动，通过师生的日常问答，复习了上节课的主要知识结构。在生生之间的对话操练环节，通过设计一个调查活动，把合作活动设置在具体、真实、自然的情景中，贴近了学生的生活，这样能更好地激发学生的兴趣，吸引更多的学生主动、积极地参与教学活动。)

Step 2 Pre-reading

2. A survey

Ask students to make a survey. Talk about what their partners have done recently. Then complete the following questionnaire.

-What have you done recently?

-I have made a poster about space travel.

1. Greetings.

- Have you had your breakfast / lunch?

- Have you cleaned your classroom?

- Has your father gone to work today?

…

3. Finish workbook Page 120 Exercises 2 & 5

Unit 2 We haven’t found life on other planets yet.

Step 1 Revision

2. Search the Internet, and try to find some materials about the nine planets of the sun.

1. Pronunciation and speaking. (Activity 7)

2. Information gap　

　 Ask students to suppose: one of the classmates is an astronaut in a space station, now he is talking to his son / daughter through TV about what they two have done recently. Then tell students to work in pairs and finish the sheets. (表格见附录 Page7，Page8 )

(设计说明：在这个环节中，通过创设信息差，吸引学生积极参与课堂活动。在传统的教学模式中，我们常用生生之间一问一答的方式，操练与巩固句型。但由于缺乏特定的情境，这样的活动只操练句型，而忽略意义，无法调动学生的兴趣。而信息差的创设可以使原有的活动变得有意义。学生必须使用目标语言来获得想要的信息，实现了“用英语做事情”这一教学基本目标。)

Step 5 Writing competition (Activities 8 & 9)

Show students the photos of Chinese famous astronauts Yang Liwei, Fei Junlong and Nie Haishen. Ask students to talk in groups of four about what we Chinese have already done about the space travel and what we haven’t done yet. First, students work by themselves in three minutes, then share his / her ideas with the workmates in three minutes, finally the groups show their ideas before the whole class. The one who has the longest list will win the competition.

(设计说明：本环节的活动是上一环节活动的延续。以航空为话题强化学生对现在完成时的运用能力。在活动中将学生自主学习与小组合作活动相结合，旨在培养学生独立自主的学习能力及分享观点，相互协作的能力。)

Step 6 Homework

1. Show students a video and some pictures of space stations, and introduce the basic structures of a space station. Then ask students to discuss in groups of four to find the differences between the life on earth and the life at a space station. They may use “We can… but we can’t….”

(设计说明：这个活动为学生展开丰富的想象提供了充分的空间，同时，还兼顾了学科之间的渗透。学生可以利用已掌握的科学知识，大胆地想象，甚至可以提供创造性的答案。这都有利于学生逻辑思维能力与创新能力的培养。另外，这个活动还为下一活动的开展作了较好的铺垫。)
