Unit 4 Astronomy: the science of the starsPeriod 1 Warming up and new wordsTeaching Goals:1. To arouse Ss’ interest in the knowledge of astronomy and science。
.2. To develop Ss’ ability in listening and speaking.Teaching Procedures:Step 1. Leading- inGive Ss a few minutes to say something about science by asking the following questions.（1.）Who is the first man in space，do you know？（2.）Which spaceship did Yang Liwei take to space？（3.）Do you want to go to space if you are given a chance?Step 2. Warming UpPurpose: To introduce the topic of this unit to Ss in the form of asking questions and discussion.Ask some Ss the questions first and then get Ss to discuss with each other. If time permits, have one or two groups present their answers to the whole class. (1) How many subjects are we studying now?（2）Do you have some scientific studying methods to learn them well?(3) As you see, a large number of students want to become scientists in thefuture. But what kind of qualities and skills do we need to be realscientists?Step 3. Talking (Workbook)1. Divide Ss into six groups, and ask them to talk about the request of Talking on P62 and answer the following questions. Different students will give different answers. Make notes of some valuable information and make a conclusion at last.(1) What necessary instructions should new space travelers make?(2) Can you make a list of them?2. Show Ss some beautiful pictures of the university and say, “Now look at the pictures. How beautiful the Universe is! It is also full of mysteries. Have you ever dreamed of flying to the space like Yang Liwei to unlock the mysteries of the universe? If you could, what things should you pay attention to?”3. Encourage Ss to give as much information as possible. After the discussion, write down some key words and important expressions on the blackboard to help Ss to have the sense of traveling in space .Conclusion:Before making a trip into space, we’d better make full preparations, such as : collecting as much information about the space as possible; checking whether you have got the proper spacesuits or not; making sure of all the safety rules; not leaving the spaceship alone unless the space guide tells you to; paying attention to recording some important time during the space traveling and so on.Step 3. Listening (Workbook)Purpose: To develop Ss’ listening ability.To gain some experience of traveling in space1. Get Ss to look through the exercises before giving them the listening material. At the same time remind them of the new and key words: astronaut, experience, instruments, pilot, air force, rocket.2. Ask Ss to look through the questions of the first part and listen to the tape carefully. Play the tape twice. For the first time, just ask Ss to listen for the gist. For the second time, ask Ss to prepare to do the exercises. If time permits, play again in order to give the class a chance to check or complete their exercises.第（1）课时课题：书法---写字基本知识课型：新授课教学目标：1、初步掌握书写的姿势，了解钢笔书写的特点。
