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 space

1. 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.
