Example Input: Article: Last week, I bought an alarm system 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 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 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 could get into our house. However, at about 2:10a.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, 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 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.

Example Input: Article: A young man approached the foreman of a logging crew and asked for a job. "That depends," replied the foreman. "Let's see you fell this tree." The young man stepped forward and skillfully felled a great tree. Impressed, the foreman said, "You can start Monday." Monday, Tuesday, Wednesday, Thursday went by -- and on Thursday afternoon the foreman approached the young man and said, "You can pick up your wages on the way out today." Shocked, the young man replied, "I thought you would pay me on Friday." "Normally we do," said the foreman. "But we're letting you go today because you've fallen behind. Our daily felling charts show that you've dropped from first place on Monday to the last place today." "But I'm quite hardworking," the young man disagreed. "I am the first to arrive and the last to leave and even have worked through my coffee breaks!" The foreman thought for a minute and then asked "Have you sharpened your axe?" The young man replied, "No, sir. I've been working too hard to take time for that!" Our lives are like that. We sometimes get so busy that we don't take time to "sharpen" the axe. In today's world it seems that everyone is busier than ever, but less happy than ever. Why is that? Could it be that we have forgotten how to stay sharp? There's nothing wrong with hard work. But we shouldn't get so busy that we ignore the truly important things in life. We all need time to relax, to think, to learn and to grow. If we don't take time to sharpen the axe, we will become dull and lose our effectiveness.
