听力原文：Man: Now listen carefully, everybody. Here is some excellent news. Next Thursday a most interesting visitor is going to come to talk to us. He is the astronaut Dr Robert Teale, that's T E A L E. I'm sure a lot of you have heard of him. He's very famous for his journeys into space.

He's going to talk to us about space travel. Only he can tell us just what it's like to travel round the earth in a spaceship, past the moon and the stars.

The whole school is going to listen to Dr Teale. We will use the school hall because none of the classrooms will be big enough. Classes will finish at twenty past two on Thursday because the talk will start at half past. Don't be late.

If your parents would like to hear Dr Teale, we have a few extra seats. The ticket price for them will be three pounds eighty-five, but of course for students it is free.

You will hear some information about a visitor to a school.

Listen and complete questions 21-25.

You will hear the information twice.
