One morning Mrs Smith was driving home after she had done shopping. When she drove near a rubbish dump, she noticed a microwave oven(微波炉) not far from the side of the road.“John is a good electrician!”she said to herself.“Perhaps he can repair this. I'll take it home and let him try.”She picked up the oven and put it in the boot of her car. Then she drove on happily. A few kilometers later, she heard the siren (警报器)of a police car behind her. She looked in the driving mirror and saw a policeman waving to her to tell her to pull over and stop.

　Mrs Smith was very puzzled. She slowed down at the side of the road. A traffic policeman got out of the police car and walked up to her.　

“Can I see your driving license and insurance certificate(保险证)，please? ”he asked her. He copied down details of her name, address and the number of the car.“What's wrong, officer?” Mrs Smith asked. The policeman did not reply. He looked in the car and then at the back.      “Open the boot, please.”he said to Mrs Smith.

　Mrs Smith was still puzzled. She opened the boot and pointed to the microwave oven. "I found this old microwave oven a few minutes ago," she said. "I'm just taking it home to see if my husband can repair it." The policeman stared at her for a moment to see if she was telling the truth. "That's not a microwave oven." he said at last. "That's our radar set(雷达装置). It was the start of a speed trap. Do you mind if we have it back?"   Mrs Smith's face turned red. "Oh", she said," I'm very sorry. I wouldn't have touched it if I'd known what it was."
