Disposing (处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities，the waste disposal problem becomes increasingly difficult.

    During the eighteenth century，it was usual for several neighboring towns to get together to select a faraway spot as a dump site. People would transport household rubbish，rotted wood and old possessions to the site. Regularly some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by. Factories and some other industrial sites also had waste to be disposed of. Those located on rivers often just poured the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.

    Several facts make these choices unacceptable to modern society. The first problem is space. Dumps(垃圾场)， are most needed in heavily populated areas. Such areas rarely have empty land suitable. Farm areas are refusing to accept rubbish from elsewhere，cheap land in major city areas to dispose wastes is nonexistent(不存在的). Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers，ground water，land and air is a price people can no longer pay to get rid of waste. The amount of waste，however， continues to grow.

    Recycling efforts have become commonplace，and many towns require their people to take part. Even the most efficient recycling programs，however，can hope to deal with only about 50 percent of a city's reusable waste，so more people should be involved in recycling programs.

    94% of 3-and 4-year-olds have been spanked(打屁股) at least once during the past year, according to one study.

    74% of mothers believe spanking is acceptable for kids ages 1 to 3, says another study.

    61% of parents take spanking as a "regular form of punishment" for young children, according to a different study.

    Sometimes children do not do what their parents tell them to do. When this happens, a parent tries to help the child to do the right thing. When this does not work, the parent usually punishes the child.

    There are many things that a parent can do. One thing that people have done is to spank the child. When a parent spanks a child, they will use their hand or a hard object to strike them on their bottom. This is meant to show the child that they have done something wrong.

    One parent remembers being spanked when he was a child. His parents used a wooden spoon. When he spanked his own children with his hand, he saw that he put a red mark on his child's leg. He never did that again.

    One problem with spanking is that it teaches the child to hit someone when they do not like what the other person is doing. Another problem with spanking is that the parent is usually angry and can hit the child too hard. Sometimes parents will use spanking for everything and not try other ways to get the child to do the right thing.

    Many parents are not sure of what to do instead of spanking. Some people think that their religion tells them that spanking is okay. Some think that the law lets them do it. The courts say that parents have the right to teach their children how to behave.

    Other things should be tried before a parent decides to spank a child. Telling the child exactly what is wanted from them can be one thing. Giving a child more than one choice is another thing that can be tried. Getting down to the child's level and taking a more child-friendly approach can help as well.

    Australian electronics and homewares retailers are preparing for the invasion (涌入) of American giant Amazon, but some have decided to take the fight up to the online-based store when it comes to local shores.

    Last week, Amazon confirmed its rapid Australia expansion by announcing that it was searching for a site to build its “fulfillment center”—a large warehouse(仓库)for storing and shipping goods purchased online—but local retailer, including one of Harvey Norman's founders Gerry Harvey, have said they will make it hard for Amazon to succeed in Australia.

    Harvey Norman sells electronics, furniture and bedding—all markets in which Amazon hopes to hold a stake, but Harvey has said that he will happily go toe-to-toe with the American behemoth to hold his ground in the Australian market.

    “In America and other parts of the world, they have just demolished (彻底打败) other retailers, no question about that, and they send a lot of retailers broke,” Harvey told News Corp on Monday. “There is no question they have one ambition and like Attila the Hun, or Alexander the Great, they just want to demolish everything in front of them and then at the end of the day claim to be victorious and make their own rules. So this is a company that is extraordinary by any measure and challenges every rule that has ever been written about a business.”

    Some analysts have said that Amazon could take in as much as 3 billion U. S. dollars in sales in its first five years in Australia (around I percent of the total 225 billion U.S. dollar market), but Harvey has refuted those claims, saying that local retailers would be putting up “one hell of a fight” when Amazon launches is main retail services in Australia. “We will be over there fighting them like no American retailer has ever fought them,” he said. “Any price that they put we will beat or equal.”

    Meanwhile, Harvey's thoughts were backed up by the former CEO of supermarket chain Woolworths. Roger Corbett, who said Amazon would struggle to keep its lower wages and claims of lightning fast delivery to rural parts when it opens in Australia. “Amazon will have an impact on the market place, but they are coming into an already very competitive market,” he told News Corp.

    One of the most important things in the world is friendship. In order to have friends, you have to be a friend. But how can you be a good friend at school?

    Listen — Listen when they are talking. Don't say anything unless they ask you a question. Sometimes it's not necessary for you to have anything to say; they just need someone to talk to about their feelings.

    Help them — If your friend is ever in need of something, be there to help them. You should try to put them first, but make sure you don't do everything they want you to do. Try to take an extra (额外的) pencil or pen with you to classes in case (以防) they forget one. Have a little extra money in your pocket in case they forget something they need.

    Be there for them — Try to make something for your friend to help make them feel better in hard times. Making cards and encouraging them are among the nicest things you can do for a friend. Marilyn Monroe, a famous U.S. actor, once said, "I often make mistakes. Sometimes I am out of control. But if you can't stay with me at my worst, you are sure not to deserve (值得) to be with me at my best." Always remember this! If you don't want to stay with your friends when they're in hard times, then you don't deserve to be with them when they're having a good time!

    ______—Try to make plans with your friends.  Go shopping, go for ice cream, have a party, go to a movie and so on. Take time to know each other even better by doing something you both enjoy. By planning things together, you both can have a good time. And you'll remember these things when you're all old!

    It's 2035. You have a job, a family and you're about 40 years old. Welcome to our future life.

    Getting ready for work, you pause in front of the mirror. “Turn red,” you say. Your shirt changes from sky blue to deep red. Tiny preprogrammed electronics (智能电子元件) are rearranged in your shirt to change its color. Looking into the mirror, you find it hard to believe you're 40. You look much younger. With amazing advances in medicine, people in your generation may live to be 150 years old. You're not even middle aged!

    As you go into the kitchen and prepare to pour your breakfast cereal（谷物） into a bowl, you hear, “To lose weight, you shouldn't eat that,” from your shoes. They read the tiny electronic code on the cereal box to find out the nutrition details. You decide to listen to your shoes. “Kitchen, what can I have for breakfast?” A list of possible foods appears on the counter as the kitchen cheeks its food supplies.

“Ready for your trip to space,” you ask your son and daughter. In 2005 only specially-trained astronauts went into space—and very few of them. Today anyone can go to space for daytrips or longer vacations. Your best friend even works in space. Handing your children three strawberries each, you add, “The doctor said you need these for space travel.” Thanks to medical advances, vaccination shots (防疫针) are a thing of the past. Ordinary foods contain specific vaccines(疫苗). With the strawberries in their mouths, the kids head for the front door.

    It's time for you to go to work. Your car checks your fingerprints and unlocks the doors. “My office, autopilot,” you command. Your car drives itself down the road and move smoothly into traffic on the highway. You sit back and unroll your e-newspaper. The latest news downloads and fills the viewer. Looking through the pages, you watch the news as video film rather than read it.

    I believe children have a very pure sense of humor. Well, I would like to share my experiences with you.

    The other day when I was out with a friend and her daughter Jane at a restaurant, Jane ordered an apple dessert, which was the most attractive dish in that restaurant. However, when she had a bite of the pie, she shouted loudly, "Mom, why does it look good but tastes like rubber?" My friend was uneasy. Then the waiter gave us another dish.

    A child can say funny things. I was at a friend's home for tea and her son, Mark, wanted her to get up. His mom replied, "I can't, because my foot has fallen asleep now." Little Mark then sang a song and asked, "Mom, will it wake up now?" We laughed together.

    The other day we were having an interesting conversation over lunch and my friend, an animal activist (积极分子) , was arguing with another group member. Her son Tommy suddenly stood up, “Mom, people should never be allowed to shoot extinct animals!” That was funny and the child did manage to turn the argument into a pleasant conversation.

    Well, children sometimes really surprise us. I think we can have a lot to learn from them. They can help us understand the simple world through their eyes.
