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.

     "You see someone just sitting there, looking like they're stupid," explains teenager Manny Logan excitedly. "You just run up to them, slap(掌击) them and run off. It's funny."

    The 16-year-old Logan was describing "happy slapping". It's supposed to be fun but it's a new problem in Britain. Young people will attack passers-by while their friends record the whole thing on camera phones. It was first reported in south London six months ago. But, the practice has spread to other parts of the country and videos of attacks have become popular on the Internet.

    The young people are called "hoodies" because they usually wear a sweatshirt with a hooded top. The top can be used to cover the head or face.

    One study in England published earlier this year suggested that as many as one in four teenagers is an active offender. That includes both serious crimes and small acts like not paying for a bus ticket.

    The fear of youth crime has left some parts of towns empty of ordinary people.

    So, the British government declared war on public disorder last week. The Prime Minister has supported a decision by the country's biggest shopping centre in southeast of England to ban teenagers wearing hooded tops. The clothing helps troublemakers hide from the centre's cameras.

    This week, the government is going further. It plans to force teenage offenders to wear orange jackets while they do public service. The idea is to shame them in front of others.

    But some teenagers and experts have complained that, in their rush to stop the hoodies, politicians risk tarring all teenagers with the same brush.

    When we talk about stars, especially women stars, it seems that they are always young, pretty and own charming body shapes. But recently a Britain's Got Talent（英国达人）star Susan Boyle has changed our views absolutely.

    Simon Cowell, one of the judges of the talent show spoke of his shock over Ms Boyle's voice. "This lady came up, and I'm thinking, 'This will take five seconds and I can go to have a cup of tea'. That changed when she began to sing I Dreamed to Dream from Les Miserables. She knew we were going to have that reaction and just to see that look of satisfaction on her face through -it was one of my favorite moments," Cowell said.

    The performance was posted on line and before long, the 47-year-old Scottish woman has been famous all over the world.

    Speaking from her home in Scotland, Ms Boyle said that she hasn't thought of changing her appearance. She said that her friend helped her with make-up. "I mean, that's hardly a makeover（改头换面）," she added. Ms Boyle also spoke of the reason she first began to explore her vocal talents, "I was kind of slow at school, so getting like singing was a good way of hiding behind that and thus it built my confidence."

    Children have their own rules in playing games. They seldom need a referee(裁判) and rarely trouble to keep scores. They don't care much about who wins or loses, and it doesn't seem to worry them if the game is not finished. Yet, they like games that depend a lot on luck, so that their personal abilities cannot be directly compared. They also enjoy games that move in stages, in which each stage, the choosing of leaders, the picking-up of sides, or the determining of which side shall start, is almost a game in itself.

    Grown-ups can hardly find children's games exciting, and they often feel puzzled（迷惑的）at why their kids play such simple games again and again. However, it is found that a child plays games for very important reasons. He can be a good player without having to think whether he is a popular person, and he can find himself being a useful partner to someone of whom he is ordinarily afraid. He becomes a leader when it comes to his turn. He can be confident, too, in particular games, that it is his place to give orders, to pretend to be dead, to throw a ball actually at someone, or to kiss someone he has caught.

    It appears to us that when children play a game they imagine a situation under their control. Everyone knows the rules, and more importantly, everyone plays according to the rules. Those rules may be childish, but they make sure that every child has a chance to win.

     The World Meat Free Day for 2017 falls on 12, June, but what would actually happen if the whole world suddenly went vegetarian(素食的) permanently?

     If vegetarianism were accepted by everyone by 2050, the world would have about seven million fewer deaths every year. No meat would lower the chances of some diseases or even some cancers and so save the world 2-3% global GDP in medical bills. Food-related emissions would drop by around 60%. This would be due to getting rid of red meat which come from methane (甲烷) producing livestock (家畜) — from people's diets. Turning former pastures (牧场) into native habitats and forests would slow climate change and bring back lost biodiversity, including some animals which were previously pushed out or killed in order to keep cattle.

    However, farmers in the developing world could really suffer. Arid and semi-arid lands can only be used to raise animals as there's no or little water in these places, such as the Sahel land strip in Africa next to the Sahara; nomadic (游牧的) groups that keep livestock there would be forced to settle permanently and lose their cultural identities if there were no more meat. Losing meat also means that we also lose traditions. There's no more Christmas turkey. We would need to replace meat with nutritional substitutes, in particular for the world's estimated two billion-plus unhealthy or weak people for lack of nutrients. Animal products contain more nutrients per calorie than staples like grains and rice.

    Everybody currently engaged in the livestock industry would need to be retrained for a new career. This could be in agriculture, reforestation or producing bioenergy. Failing to provide career alternatives could lead to mass unemployment and social problems, particularly in traditionally rural communities.

    “Belittle” was first used by Thomas Jefferson, the third president of the United States.

    Many years ago, Buffon, a French naturalist, wrote some books about natural history. The books were a great success even though some critics did not like them. Some critics said, “Buffon is more of a poet than a scientist.”

    Thomas Jefferson did not like what Buffon had said about the natural wonders of the New World. It seemed to Jefferson that Buffon had spoken of natural wonders in America as if they were unimportant.

    This troubled Thomas Jefferson. He was a naturalist, as well as a farmer, inventor, historian, writer and politician. He had seen the natural wonders of Europe. To him, they were no more important than those of the New World.

    In 1788, Thomas Jefferson wrote about his home state, Virginia. While writing, he thought of its natural beauty and then of the words of Buffon. At that moment, Jefferson created a new word－belittle. He said, “Buffon believes that nature belittles her productions on this side of the Atlantic.”

    Noah Webster, the American word expert, liked this word. He put it in his English language dictionary in 1806, “Belittle－to make somebody or something small, unimportant.”

    Americans had already accepted Jefferson's word and started to use it. In 1797, the Independent Chronicle newspaper used the word to describe a politician the paper supported. “He is an honorable man,” the paper wrote, “so let the opposition try to belittle him as much as they please.

    In 1872, a famous American word expert decided that the time had come to kill this word. He said, “'Belittle' has no chance of becoming English. And as more critical writers of America, like those of Britain, feel no need of it, the sooner it is forgotten, the better.” This expert failed to kill the word. Today, “belittle” is used where the English language is spoken.
