My son Cameron who was 16 years old came up with this crazy idea to make his own survival show. Well I thought it was just another one of his “phases” but he began to sound more and more serious about it. He's a big outdoors man and has always loved the idea of surviving in the woods by himself, but he has never done anything like this. Anyway, he somehow raised $4,000 for his idea. With the money he bought a nice camcorder(摄像机) ;that's when I realized that he was really serious about this whole thing.

    Cameron organized the trip all by himself. I just put out a few rules that he had to follow and rented a satellite phone so that he could contact us on his journey. My son traveled nearly 50 miles, while surviving for four days and three nights alone in the wilderness. He had no food or water, only his knife, and a camera. The journey was difficult as he traveled through valleys, up and down big waterfalls, all while he was filming his entire journey. The wilderness we dropped him off in was a wild forest that is made up of untouched land; he found his way to the beautiful lake where we picked him up. In the end he made the most amazing movie that I have ever seen in all my life.

    My son's courage should be recognized. That is why I am trying my hardest to get him seen by the rest of the world. Cameron recently turned 17. He already has plans for his next adventure and I have no hope in stopping him from completing it. This next summer he plans on surviving for two or three weeks on a desert island in Fiji or Tonga. No teenage kid has ever done anything close to what my son Cameron has done.

    Although one might not think so as a result of the disadvantages, thousands and thousands of ads have shown advertising is of great importance to the society in which people live, either in the United Kingdom, or in many other parts of the world .Advertising is necessary as a means of communicating with others, of telling them about the goods and services that are offered, and of which most of them would never get to hear at all if it were not for advertising. And advertising does a great deal to a rising standard of living conditions.

    In talking about advertisement, one should not think only a commercial on television, or an advertisement in the newspaper or magazines and—in the sense of communication—even the spoken or written words of salesmen. After all, the roots of advertising are to be found in the market place in the ancient times.

    For many years it was thought that it was not enough to just produce goods and supply services. It is only more recently that people came to understand the production of goods would be a waste of resources unless those goods can be sold at fair price within a reasonable time period. In the competitive society in which we live, it is very important that we go out and sell what we have to offer, and advertising plays an important part, whether selling at home or in export market. Around 2 percent of the UK national product is spent on advertising. But it must be thought that this advertising tries to sell goods to customers who do not buy them. Of course, advertising does try to catch the eyes of the buyer, but if the product one has bought does not match what the advertisement had described, it is extremely unlikely that the goods will sell well.

    Winter solstice(冬至), an important solar term in the traditional Chinese calendar, as the name implies, means the coming of winter. It generally occurs between December 21st and 23rd. According to the traditional Chinese calendar, one year is divided into twenty-four solar terms. On this day, in the Northern Hemisphere the period of daytime is the shortest of the year and the period of night is the longest.

    In Northern China there is a custom of eating dumplings during winter solstice. The tradition of eating dumplings during winter solstice has its origin in early times. It is said that dumplings were invented by Zhang Zhongjing, a well-known doctor from the Eastern-Han Dynasty.

    One winter, he noticed that many people's ears were frozen, which made him sad. In order to prevent and cure the freezing injury caused by the cold, he asked his followers to boil mutton, chilies and other ingredients with medicinal properties in a pot for fending off cold. After these were boiled, they ladled(舀取) the mutton and other ingredients out of the pot, cut them into pieces, and then wrapped them with dough skins in the shape of ears. Afterward, they put these into pots to boil again.

    On the day of the winter solstice, the people whose ears were frozen were sent to eat the dumplings. People who ate it felt warm from head to toe and had their cold injury healed. Thereafter, every winter solstice people ate dumplings. Then there became a saying that if you eat dumplings during the winter solstice, then you won't freeze your ears off.

    Afterwards, Zhang Zhongjing died on the day of winter solstice. In order to honor him, every year on the day of the winter solstice every household makes dumplings.

    Brian Greene, a professor of physics and mathematics at Columbia University, has created an online science education platform. He tries to "build a bridge" with things you know about, and then "bring you across that bridge to the strange place of modern physics."

    Recently I had a chance to ask Greene about wormholes (a hole which some scientists think might exist, connecting parts of space and time that are not usually connected), time travel and other mysteries of the universe. I asked him a million-dollar question: What if I went through a wormhole and prevented my parents from meeting? "Most of us believe that the universe makes sense," Greene said. Although there are several interesting theories about time travel, he added, the laws of physics would probably prevent something so illogical from taking place. The good news is that the time paradox（悖论） is open for future physicists to solve.

    When asked how physics could become more exciting for kids, Greene said that books by Stephen Weinberg, Leonard Susskind, and other physicists, "make it a great time for people who want to learn about big ideas but aren't yet ready, perhaps, to learn math."

    When I pointed out that some students still might find physics boring, Greene said that the key is to teach them about things that are strange. "The basic stuff is important," Greene said. "But I think it's really important to also describe the more modern ideas, things like black holes and the Big Bang. If kids have those ideas in mind, then at least some of them will be excited to learn all the details．"

    Greene has followed Albert Einstein's lead in trying to solve the mysteries of the universe. Now he wants kids to do the same. As Greene said, physics is "not just a matter of solving problems in an exam." It's about experimenting, showing an interest in strange phenomena（现象）-- and having fun!

    Studying abroad will shape you in various ways. You will learn things you never would have if you had stayed home. When you are young and unattached, you should travel. Besides, you just might save a large sum of money. College is expensive in the United States. It's cheap or free in other countries even for foreigners, so why not get out of here and come back smarter?

    More and more American students are currently studying at German colleges. That number has increased 20% over the last three years. Living costs are about $7,000 a year, which is even lower than in other European countries. Germany encourages international students. They create a multicultural landscape that benefits German students as well. According to a new report, Germany is home to six of the world's 100 best universities. These schools offer around 900 degrees completely in English and many German students speak the language.

    You could be part of Finland's excellent education system. The Finns charge no tuition and offer a number of courses purely in English. They would be happy for you to add flavor to their school scene. Cost of living there is high. Be prepared for frosty winters that far north, but you will get that sweet midnight sun in the summer.

    Many other European nations offer cheap or free college for foreign students, but if South America is more your thing, try Brazil. Most of the education will take place in Portuguese, so if that is in your plan you can study near beautiful beaches and jungles. The University of Sao Paulo and the State University of Campinas are both highly ranked internationally. Your money will go a long way there, too.

    Many of the lessons you will learn will be outside the classroom. Living on the economy in a foreign country will keep you on your toes. You will learn new customs, how to bargain, stay safe, budget and become more flexible with people. There is no better way to learn a language than by immersing yourself in it. At first, it will be the toughest thing you have ever done. Eventually, it will become second nature.

The American Psychological Association（APA） has issued its first advisory on social media use in adolescence（青春期）. What's most striking in its data based on recommendations is how little we really know about how these apps affect our kids.

The relative newness of platforms like Snapchat and Tik Tok means little research is available about their long-term effects on teen and tween brains. Getting better data will require significant funding—and much more openness from tech companies.

"What little evidence we do have unsurprisingly suggests that social media trades on motivators that aren't great for young brains. Many kids' first exposure to social media occurs at the worst possible time when it comes to brain development," says Mitch Prinstein, a psychologist and neuroscientist at the University of North Carolina（UNC）.

"Things like 'button and artificial intelligence（in general）' are going to affect young people's brains in a way that's very different from adult brains when it comes to the desire to stay online and to say or do almost anything to get followers." When it comes to social interactions, he compares kids' brains to a car with a huge gas pedal and weak brakes（刹车）.

Earlier this year, Prinstein and his UNC colleagues published the results of one of the first studies of how the adolescent brain reacts to social media. The team surveyed a group of middle schoolers to understand their social media habits, and then stuck them in an MRI machine to watch their brains as they reacted to social rewards or punishments. They found that 12-year-olds who habitually checked social media had distinct neural patterns, with more activities over time in parts of the brain associated with motivation, salience（or where attention is focused） and cognitive control.

The team didn't weigh in on whether those differences were good or bad, or whether the relationship was causal or correlational. But their work points to the need for more research. It should also remind parents of the need to be keenly aware of social media's hidden influence on still-developing brains.
