题目内容
Last week, I bought an alarm system(报警系统) for about $ 450. It consisted of a control unit with three other small units. I put the control unit in the sitting room and fastened the other units by the front door, back door and living-room windows. The instructions told us to choose three numbers, so we chose 491, the last three numbers of our telephone number.
Now I must explain how the alarm works:
1. There is a power siren(警报器) in the control unit. It makes a very loud noise.
2. Each of the small units sends out beams(光束) or rays in different directions. If anything moves, it breaks a beam. This sends a signal to the control unit. The siren makes a noise that you can hear 50 meters away.
3. When we go to bed, I press the three buttons numbered 4, 9 and 1. Then we have 30 seconds to get out of the room before the alarm starts to work.
That might I slept soundly because I was sure that no burglar(夜贼) could get into our house. However, at about 2:10a.m., I woke up and heard the siren(警报).
“There must be a burglar in the house,” Mary said. “What shall we do?”
“I’ll go and see who’s there,” I said. “Stay here. Don’t make a noise.”
I went downstairs quietly. When I reached the living room, I switched on my torch and looked round the room. Then I turned the light on. I switched the siren off and searched the rooms downstairs. There was nothing wrong except that the back door was unlocked. I locked it, re-set the alarm and went back to bed.
About an hour later, the alarm started again. I jumped out of bed, fell over a chair in the dark and bumped into the bedroom door. Mary woke up and started hitting me with a torch. “Hey! Wait a minute!” I whispered. “It’s only me. I’ m going downstairs to see what’s wrong.”
I went down into the living room and listened for a moment. The only sound I could hear was the siren. I turned on the light and then switched the siren off. As I did so, I glanced across at the curtains in front of the windows. I saw a house lizard (蜥蜴) disappear behind the curtains.
“Oh!” I said to myself. “That’s our burglar.”
When the lizard moved, it started the siren. I guessed that the alarm had been made in Europe, where there are no house lizards.
Well, I won’t finish this story but if you want an alarm system free of charge, let me know. I’ll send you ours. We bought a dog this morning. It knows the difference between a lizard and a burglar.
