Step 1 Lead-in
1. Word map construction
Show students a video about humans landing on the moon, and ask students to say out the things they see. Help students to answer: astronauts, spacecraft, the moon and so on. Then ask students to work in groups of four. Try to think out more related words like: earth, scientists, stars, space shuttle, sun, planet, universe, space station, air, space and so on.
（设计说明：这个环节的设置旨在培养学生的自主学习、合作学习与发散思维的能力。学生在观看录像之后，说出已知的单词，并尝试联想相关词汇。学生通过合作探究，自学新的知识，若在反馈中出现错误，老师可适当纠正。这些都为下面的听力环节解决了语言上可能出现的困难。）
2. Ask students to answer some questions about this video.
①. How did the astronauts go to the moon?
②. How many spacecrafts has America sent to the moon by now?
③. Have they discovered life on the moon?
④. Have the scientists sent spacecrafts to Mars yet?
⑤. Have they discovered life on Mars yet?
设计说明：此环节可以帮助学生更深入地了解人类登月的历史。最后的两个问题，很自然的将讨论的话题由登月过渡到火星探索方面，由此引出了接下来的内容，起到承上启下的衔接作用。另外，这些问题的设置很自然的引出该堂课的重点句型：Have they …yet? Yes, they have just / already…. No, not yet. / No, they haven’t yet.）
Step 2 Listening (Activities 1 & 2)
1. Tell students to listen to a piece of news about the travel mission to Mars and find the answer to the question “Have they discovered life on Mars yet?” and finish Activity 1: Listen and number the words as you hear them.
2. Listen again and finish Activity 2: Check the true sentences.
Step 3 Listening and reading (Activities 3, 4, 5)
1. Tell students Da Ming’s friend Tony has made a model of a space station, and now they are talking about the model. Ask students to listen and read the dialogues, then try to answer three questions: ①. Has the spacecraft to Mars arrived yet?
②. Have many astronauts been to the moon recently?
③. How do the astronauts go back to the earth from the space station?
2. Ask students to read the dialogue again and finish Activities 4 and 5.
3. Students read after the tape and then act out the dialogue.
（设计说明：通过这一环节的学习，学生们对火星探索计划的了解更为透彻了。而朗读与表演对话则能使教学内容得到进一步的巩固与提高。）
Step 4 Tasks (Activity 6)
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。）
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 )
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. Pronunciation and speaking. (Activity 7)
2. Search the Internet, and try to find some materials about the nine planets of the sun.
3. Finish workbook Page 120 Exercises 2 & 5
个性教学
这有利于学生发散思维能力的培养;
若涉及未学过的词汇，学生可以通过小组互助合作查找出来，改变了由老师教，学生学的传统的单词教学的模式。
设计说明：本活动为听力基本能力训练，是一种听力输入理解活动。听力的相关内容对火星探索计划作了简单的介绍，为学生能更好的理解下一环节中的对话内容作了铺垫。
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。
反馈矫正
