Last week, I bought an alarm system for about $ 450. It consisted of a control unit with three 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 4, 9 and 1, the last three numbers of our telephone number.
Now I must explain how the alarm works:
l 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 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 which 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 night I slept soundly because I was sure that no burglar(夜贼) could get into our house. However, at about 2:10 a. m., I woke up and heard the siren. “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, reset 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 (a kind of small animal) 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.

I have been using the Internet since I was five years old, when my dad first sat me down in front of a computer and connected me the World Wide Web.
I’ve always felt like a master of the Internet world. AOL Instant Messaging, MSN, Gmail, Facebook, Myspace -- I’ve got it all under control. I thought there was nothing more to it besides checking my e-mail and wasting my time, until I was introduced to electronic commerce(e-commerce): business on the Internet.
Some online businesses are run from one-room home offices. Others have hundreds of employees (雇员) across the world. Have you ever heard of Amazon.com, Yahoo.com?
My friends often said they got cheap textbooks off Amazon.com, or had a good deal (交易) on Steve Madden shoes that were on sale at SteveMaden.com. Unfortunately for me, I continued my “e-commerceless” Web-surfing, not knowing about all the deals I was missing out on.
That is, of course, until my sister finally sold the idea to me.
“Why are all these packages arriving in the mail for you, Katy?” I asked her one day. Strange envelopes (信封) had been put on our doorstep for weeks now, each one always addressed to my sister; and we all know little sisters should never be getting more mail than their elders!
“Oh, it’s the things I ordered online!” she answered. I watched speechlessly as she opened them. There was no way our parents were letting her spend that much money- online or off!
“How much did all of this coat?”
“Oh, only about $15 in all!” She said excitedly. “Everything on eBay is on sale! It’s a way better than going to the mall.”
I felt as if there had been a store right in my backyard that I had never walked into! That week, I ordered a used Spanish textbook for my summer course online for 10 percent of the publishing price. A few days later, I bought an iPod protector and a book or two via the wonderful eBay.com.

Last week I bought an English dictionary in a bookstore near my home. So when I came home and read carefully I found that several page of the dictionary had been missing. Worse still, the misprints spread everywhere the dictionary and serious affected my reading. I went to a store to ask for a replacement. But to my surprised, the staff of the bookstore turn down my request rudely and even denied the poor quality of the dictionary. It goes without saying what a high standard of service is needed in today’s society. However, to my regret, businessmen are fail to achieve this standard. The quality of the staff needs improve.
