听力原文：W: Dad!
M: Yes？ What's the matter, Krista？
W: I'm wondering if I should buy a pair of tennis shoes. I'm going to join the tennis club in school.
M: Why not？ It's good that you finally play sports.
W: But I'd like to have Adidas.
M: Adidas？ It's expensive. It's for the Chicago Bulls!
W: No. All the guys on the school tennis team are wearing Adidas, boys, as well as girls...
M: But none of us has ever had Adidas and we used to play quite OK.
W: Here, Dad, is an ad about Adidas. Can I read it to you？
M: Go ahead.
W: "Over forty years ago, Adidas gave birth to a new idea in sports shoes. And the people who wear our shoes have been running and winning ever since. In fact, Adidas has helped them to set over 400 world records in track and field alone."
M: Nonsense! The players have to go through a lot of hard training and practice. It's nothing to do with the shoes. They may be comfortable, but...
W: You are right, Dad. The ad goes on to say "You are ham to run. And we were ham to HELP YOU DO IT BETTER."
M: Hmm. Maybe good for running, but you don't run.
W: Listen, "...Maybe that's why more and more football, soccer, basketball and tennis," see？ "TENNIS players are turning to Adidas. They know that, whatever their game, they can rely on Adidas workmanship and quality in every product we make."
M: OK, OK, dear. I know Adidas is good. But how much is a pair of your size？
W: You don't have to worry about that, Dad. I've saved some money since last Christmas. I just want to hear your opinion.
M: That's good. I have been wanting to have a pair of Adidas sneakers myself.

听力原文： It was about half past eleven on a windy September night and Mr. and Mrs. Wilkinson had gone to bed early. They had put out the light and were just going to sleep when Mrs. Wilkinson heard a strange noise coming from downstairs. Mr. Wilkinson got up to investigate. When he reached the bottom of the stairs he noticed that the noise was coming from the dining room, and it sounded as ff someone was trying to open the French window that led into the garden.
Mr. Wilkinson was quite frightened but he gathered up his courage, picked up a heavy walking stick and tiptoed into the dining room moving around the side of the room so that he wouldn't be seen from the window. When he got to the window, he crouched down and peered cautiously round the edge of the curtain. To his relief, he saw that the noise was nothing more than a branch of a rose scraping against the window in the wind.
