When he was a little child, Andrew had a serious bad habit of sucking（吮吸） his fingers all day long, especially when he had nothing interesting to do: when he was sleeping, when watching TV, when sitting on the sofa and so on. At the beginning, his parents didn't think it was a bad habit.
Therefore, as time goes by, the boy couldn't give up his habit. Now, in his twenties, Andrew seems to have developed the bad habit into another one: he always bites his nails(指甲). He cannot stop biting his nails all the time. There're moments when he even doesn't know that he is doing it. He realized it was a problem and this worried him a lot. Some of his friends told him about this bad habit, and he stops for a while. But then, if he isn't busy doing something, he starts biting his nails again!
In fact, there're a lot of bacteria(细菌) in your nails and they can cause some disease. Also, the nails will become ugly and hard to recover. The worst thing is that this bad habit will bring the mental illness（心理疾病）. If people cannot correct it in time, it can affect man's mental health.
In short, bad habits are very worrying, especially when the person with the habit is in public and cannot stop himself or herself doing it. Still, there must be ways to give up these bad habits and these people should try their best to stop doing them.
Computers are useful machines．They can help people a lot in their daily life．For example，they can help people to save much time to do much work，and they can help people to work out many problems easily．Our country asks everyone to learn to use computers before the twenty-first century，except the old people． 21·cn·jy·com
Today more and more families own computers．Parents buy computers for their children．They hope computers can help them improve their studies in school．Yet，many of their children use computers to play games，to watch videos or to chat．Computers can not help children to study but make them fall behind．So computers are locked in boxes by parents．
In some other countries，even some scientists also hate computers．They say computers let millions of people lose their jobs or bring them a lot of trouble．Will computers really bring trouble to people or can they bring people happiness? It will be decided by today's students themselves!
A week in the sun relaxing in the beautiful March weather of Varadero, Cuba is a fantastic vacation for anyone. Luckily, my wife, two friends and I had the chance last year.
To see Cuba, you have to talk to the Cubans. Our friends met us at the airport even at 1:00 a.m. which started our trip on a positive note. After a few days at the hotels, we got to know a local tour guide, Victor.
The trip started off on a sunny morning. Our return trip would be along the coastline from Havana, but out trip to Havana would be through the countryside and the small towns. This trip was designed for us to visit the Cuban countryside.
At first Victor brought us to Revolutionary Square, where Fidel Castro made his yearly speech praising the ideas of the revolution.
Our second stop was the Bocoy Rum Factory. We walked through and learned how 5000 bottles of rum(朗姆酒) are produced every day. The smell of rum, and the huge barrels were interesting.
The final stop was the market in Old Havana. Here my wife and I went away from our friends and we toured through this large shopping center. From store to store we saw so many items that all had a clear Cuban feel to them. We bought a picture and some special local things, and then we took off to meet up with Victor.
As a tourist I was able to have a quick look at Cuban life with the help of Cubans. I felt lucky to have the chance. It was an interesting experience in my life.

Do you live in a city? Do you know how cities began? Long long ago, the world had only a few thousand people. These people moved from one place to another. They moved over the land, hunting animals for food. No one knows how or when these people learned about growing food. But when they did, their lives changed. They did not have to move houses any more. They could stay in one place and grow it. People began to live near each other, so the first village grew. Many people came to work in the villages, and these villages became larger and larger. Then people had machines, life in the villages changed again. People built factories. More and more people lived near the factories. So the villages grew into cities. Some of them grew very big. Today, it's strange that some people are moving back to small villages. Can you tell me why ?
