As children begin to head back to school, there are several things that you can do to make sure that your child stays healthy and performs at their peak potential during the school year.

    1). Make sure your child is up to date on their immunizations(免疫). The summer is a good time to schedule visits to the doctor's as your child is not in school, and the visit won't require that your child miss school days.

    2).Encourage proper nutrition. America faces childhood obesity(肥胖). This means that the percentage of overweight children is increasing each year, and this will place your child at risk of developing a variety of diseases when they are middle age or even young adults. You can start helping your child to become healthier by offering fruits and vegetables at home instead of calorie heavy potato chips and candy.

    3). Get your child involved in sports activities. Activities in high school such as track and cross-country are important for socialization for your child, as well as helping to improve their health. You can get your child interested in wholesome activities by discussing with them how you enjoyed similar activities in high school.

    4). Have the birds and the bees conversation with your child. Many children become sexually active in junior school and senior high school, and the sooner you discuss sex with your child the sooner they will be prepared. Tell your child that there is always the possibility of infecting a sexual disease when two people have sex; and discuss with your child the use of condoms. The sooner you start having this embarrassing situation the better.

    5). Know your child's friends. You can do this by inviting your child to bring their friends over to your house for a pizza night, or by chatting with them when they stop by your house. If you find your child's friend has a bad reputation, then you could consider introducing your child to a different network of people, such as through the girl/boy scouts. Forbidding your child from seeing a certain person may only lead them to rebel and become closer to that person.

    6). Discuss with your child the seriousness of drug use and abuse. Your child may not realize that using drugs can have serious consequences. Your child may get the false impression that drug use is his right. Explain to a child that saying no to drugs is their right, and that anybody offering them drugs is not their friend.

    7). Help your child to avoid a life long smoking addiction by discussing with them the consequences of smoking. The sad fact is that most smokers became addicted when they were in their teenage years, and are unable to quit for long periods of time and often die many years earlier due to their smoking habit which increases the risk of lung cancer, heart disease, and a variety of medical conditions. Even if you are a smoker yourself, you can discuss with your child about how damaging smoking can be on a person's health.

    8). Impress upon your child the importance of traffic rules. Tell them that it is OK to wear a seat belt in anyone's car, because it may save their life one day. If your child rides a bicycle or a skateboard, then discuss with them the importance of always wearing a helmet. As you child becomes qualified for driver's permit, you should discuss with them the importance of prevention from drinking and driving.

    9). Be cautious about signs of depression in childhood. A surprisingly large number of children may become depressed, and a small number of teenagers and children commit suicide(自杀) each year. Realize that any signs of unusual depressed mood, angry outbursts, suicidal comments, feelings of hopelessness, and loss of enjoyment of activities with friends may be signs of depression.

    A report says older adults who test their minds with increasingly difficult projects have better mental ability than those who do less demanding activities.

    To keep our brains sharp as we age, we are often told to keep our minds active. As the old saying goes, “Use it or lose it.” But, there is very little scientific evidence to support than.

Denise Park is head of the university's Center for ? Vital Longevity. She designed a study in which she and her tern placed 221 healthy aging and older adults into one of three groups.

    “We asked people to learn new things, like quilting or photography. We asked other people to just do fun things like being in a social group function but were not likely to have a very large effect.”

    The subjects took part in their assigned activities for 15 hours a week over three months. At the end of that time, the researchers found that the adults who learned new skills, such as digital photography, showed the greatest improvements on memory tests.

    No improvements were seen in the results of those in the social group that did activities together like going on field trips. There were also no improvements among the third group that listened to classical music or did crossword puzzles.

    Denise Park believes one reason for improved memory in the active learning group is that its members were being pushed to learn new skills. The other groups took part in what she call receptive activities. Learning new skills may not cure age-related mental decline. But, Ms. Park thinks being mentally active slows down the process.

Denise Park says the latest information shows that the improvements lasted for at least a year. She and her team plan to do longer follow-up studies with all three groups. She also is interested in learning whether taking part in demanding mental activities delays the development of conditions like Alzheimer's disease.

    At the beginning of the century there was a big farm called Hollywood Ranch. It was near Los Angeles in California. A few years later Hollywood was one of the famous places in the world. From the 1910s to the 1950s Hollywood was the film center of the world. Every family knew the names of its film stars—Charlie Chaplin，Greta Garbo，Bergman and hundreds more.

    The reason why people went to Hollywood to make films was the sun. At first people made films in New York on the east coast of the United States. But then they heard about Los Angeles where there are 350 days of sun every year. As they made all the films by sunlight，the west coast was a much better place to work. Also near Hollywood you can find mountains and sea and desert. They did not have to travel far to make any kind of film.

    When TV became popular，Hollywood started making films for television. Then in 1970s they discovered people still went to the cinema to see big expensive films. After twenty years they are still making films in Hollywood and people watch them all over the world.

    Teary-Eyed Stories from Strangers

    The Man at the Market

    When the supermarket clerk summed up my groceries, it was $12 over what I had on me. I began to remove items from the bags, when another shopper handed me a $20 bill. “Please don't put yourself out,” I told him.

     “Let me tell you a story,” he said. “My mother is in hospital with cancer. I visit her every day and bring her flowers. I went this morning, and she got mad at me for spending my money on more flowers. She demanded that I do something else with that money. So, here, please accept this. It is my mother's flowers.”

    A Family's Food Angel

    Since my mother lost her job, our family troubled new worries: no income, the same bills, and no way to afford groceries. It was around this time that she started finding boxes of food outside our door every morning. This went on for months, until she was able to land a job. We never did find out who it was and who left the groceries for us, but they truly saved our lives.

    Seven Miles For Me

    Leaving a store, I returned to my car only to find that I'd locked my keys and cell phone inside. A teenager riding his bike saw me kick a tire and say a few choice words. “What's wrong?” he asked.

    I explained my situation. “But even if I could call my wife,” I said, “she can't bring me her car key, since this is our only car.” He handed me his cell phone. “Call your wife and tell her I'm coming to get her key.”

    “That's seven miles round trip.”

    “Don't worry about it.”

    An hour later, he returned with the key. I offered him some money, but he refused. “Let's just say I needed the exercise,” he said. Then, like a cowboy in the movies, he rode off into the sunset.

    Breaking Bread

    Last December, before work, I stopped at a deli (熟食店) and ordered an everything bagel with cream cheese. It was toasty warm, and I couldn't wait to dig in. But as I left the store, I noticed an older indigent gentleman sitting at the bus stop. Knowing it would probably be his only warm meal of the day, I gave him the bagel.

    But all was not lost for me. Another customer from the deli offered me half of her bagel. I was so delighted because I realized that in one way or another, we are all looked after.

    If you analyze people's actions, you will come to the conclusion that they all seek happiness. Every act is in fact a search for it, even if on the surface it doesn't look so. Happiness is always the main target.

    Going to the movies, eating in a restaurant and going to a party are all motivated by the desire to be happy. Who does not dream of a vacation in some fascinating locations, a new car, a new house, or the ideal match? All people daydream, and some even try to make their dream a reality. And why is that? In order to be happy!

    Many people endanger themselves by climbing steep mountains, entering unexplored caves, or diving into the deep of the ocean in order to enjoy the few moments of happiness. A thief may steal because he loves the thrill of danger, or because he desires to have quick money to spend. He is actually looking for happiness, though in a perverted way.

    Of course not all actions end in happiness. The motive is happiness, but the results do not always bring the desire. According to some spiritual traditions, we are spiritual beings in physical bodies. The spiritual part is always happy. Rather, it is happiness itself. But the physical body covers this happiness essence(本质). There is a constant desire to find out this happiness. This is the reason why happiness is constantly sought.

    However, there is no need to search for happiness or to create it, or to have all kinds of outer experiences and actions in order to feel it. On the contrary, everything has to be dropped in order to experience it. Every technique, which helps to relax the mind and calm the rush of thoughts will lead to happiness.

    All of us know that smoking does harm to our health. But do you think everything will be OK as long as you quit smoking?

    Unfortunately, the answer is NO.

    New research has found that even if you give up smoking, the damage it has done to your genes (基因) will stay there for a much longer time. In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7, 000 genes of smokers had changed—a number that is one-third of known human genes. According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their daily lives while doing things like smoking. When you stop smoking, a lot of these genes will return to normal within five years. This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years, It's almost like leaving a footprint on wet cement (水泥)—it will always be there, even when you've walked away and when the cement becomes dry. Although the study results may make people unhappy, there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.
