It's Sunday morning. There are many people in Garden Shopping Mall. Mrs. Green and her son, Jim, are also in the shopping mall.

      It is Mr. Green's birthday next Thursday. Mrs. Green wants to buy a new shirt for him. Soon she finds a good one. She thinks it matches Mr. Green's black suit very well. It's $45. But Mrs. Green takes it at a 20% discount (折扣) at last.

      Jim likes sports and he is a member of the school football team. His school will have a football match next Friday, so Mrs. Green buys a pair of new sports shoes for him. Jim's sister, Kate, is busy at school with her dancing lessons. She is going to dance at New Year's party. Mrs. Green buys a pink dress for her because Mrs. Green thinks her daughter (女儿) looks pretty in pink. She also buys some pink hair clips for Kate. She thinks they match Kate's new dress well.

      As for(至于) Mrs. Green, she buys some nice food for herself because she is a food lover.

    When you sleep somewhere else, like at a summer camp or a friend's house, you know you're there for a fun time. But for some kids, when they are away from home they feel sad. They start to miss- their own beds, their own parents, and all the things at home. It's called being homesick (想家的). Do you want to feel less homesick? Here's how.

    Spend more time doing fun things. The more fun things you do, the less time you'll have to feel homesick. So try to take part in activities and soon you might start to have a good time.

    You can make a plan to call your mum or dad. For a one-night visit, maybe you can call once that night, and again in the morning. In the camp, you might set a regular day and time for a phone call home.  You can also send emails or short messages to keep in touch with family members and friends. If you're going to be away for a while, you might even write a letter! When you get in touch with someone, make sure to tell them about the fun things you're doing!

    Sometimes, just tell someone that you're feeling homesick. This will help you feel better. Maybe you can tell a friend that you feel homesick. And both of you can do something fun, such as telling jokes. If you're at a camp, a camp counselor (顾问) would be a good person to talk to. He or she might have some ideas to help you feel better.

WARNING(警告): Holding a cell phone against your ear or putting it in your pocket may be bad for your health. This sentence is a warning that you'd better not put it close to you when a new phone is bought. Apple company, for example, doesn't want iPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry's producer, recommends 2.5 centimeters.

      If cell phone use can cause health problems, the result will be very serious. Americans spend 2.26 trillion minutes chatting on cell phones every year, which brings $109 billion for the wireless businessmen.

      Devra Davis, an epidemiologist(皮肤病专家)who has worked for the University of Pittsburgh, has published a book about mobile phone radiation(辐射)"Disconnect." Davis studies how often brain cancer happens during different age groups. As a result of mobile phone radiation, she finds that a big increase(增长)in brain cancer in the 20-to-29 age group and a drop for the older people.

      Children are more easily hurt by radiation than grown-ups, Ms. Davis and other scientists point out. But no studies have yet been finished on cell phone radiation and children, she says.

      Henry Lai, a research professor, began lab radiation studies in 1980 and found that mice exposed to(暴露在) radiofrequency（电波频率）radiation had destroyed DNA in their brains.

      Ms. Davis recommends using wired earphones（有线耳机）or the phone's speaker. Children should send text messages rather than call, she said, and pregnant women should keep phones away from their bodies.

    Sometimes, it seems that with all the homework and stress, being a student can be the worst thing. For people who are being bullied (欺凌), however, having too much work to do is the least of their worries.

    Bullying comes in many different forms. It could be someone hitting you, someone sending you terrible messages on social media, or someone saying bad words to you. No matter how it happens, being bullied is never a nice experience.

Being bullied can do great harm to a child's personal development. It is hard for bullying victims to trust others. They often feel angry, no valuable, helpless and lost. And these feelings will further undermine(破坏) their ability to control their own life.

    So if you or someone you know is being bullied, how should you deal with it?

    Well, you need to find out why the bully is acting this way. The reasons behind school bullying are various. Children are now more easily influenced by violence in both real life and online. They want to gain power by bullying other students. Usually, they pick on the nicest or most well behaved person. Because this kind of persons seldom fight back. Some left-behind children become bullies because they lack (缺失) family education.

    Whatever the reason is, there are many different ways to deal with a bully. The clearest way is to share your problem with someone else. All bullying is wrong. It is important that you talk about the problem with someone you can trust. Usually the best way to end your problem is to talk to your teacher or parents. Or, in some cases, standing up to the bullies may change their behavior. If they know that their bullying doesn't work on you any more, they may stop. What's more, parents and schools should devote more time and efforts to the troubled children.

    Most importantly, remember this: If you're being bullied, it's not your fault. There's always someone to help you—you just need to ask first.

    We usually go to see a doctor when we are ill. Doctors may give us some medicine, and the medicine often makes us feel better.

    But sometimes the doctor's medicine doesn't work. This happened to one man, Thomas Smith. He was ill in hospital, but he wasn't getting well. Then he found a new "doctor" inside himself. He saw funny films. He read funny books. And something wonderful happened. Laughing took away his pain after half a year. He could have a good night's rest. His own happy feeling helped him get well again. He wrote his story in his book. He said laughing was very useful. It was the best "medicine".

    Another man, Simon Beck, was also ill, and he had a serious pain in his back. The doctor couldn't stop it, so the man began to "picture" his pain. In his head he "drew a picture of a dog. He imagined it to be a real dog. And it was hurting him. Then the man talked softly to the dog. He put his hand on the dog's head and made friends with it. One year later, his pain went away!

    These stories may surprise you, but more and more people are getting well in this way. So call on the "doctor" inside your mind, and keep happy and well!
