You may think that sailing is a difficult sport, but it is really not hard to learn. You do not need to be strong. But you need to be quick. And you need to understand a few basic rules about the wind.

    First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat. The wind direction tells you what to do with the sail.

    Let's start with the wind blowing from the behind. This means the wind and the boat are going in the same direction. Then you must always keep the sail outside the boat. It should be at a 90° angle to the boat. Then it will catch the wind best.

    If the wind is blowing from the side, it is blowing across the boat. In this case, you must keep the sail half way outside the boat. It should be at a 45°angle to the boat. It needs to be out far enough to catch the wind, but it shouldn't flap(摆动). It shouldn't look like on a flagpole. If it is flapping, it is probably out too far, and the boat will slow down.

    Sailing into the wind is not possible. If you try, the sail will flap and the boat will stop. You may want to go in that direction. It is possible, but you can't go in a straight line. You must go first in one direction and then in another. This is called tacking. When you're tacking, you must always keep the sail inside the boat.

    You may think there are no differences between British and American people. After all, they speak the same language, don't they? If you ask a British or an American person, he will probably tell you that there are differences. And the differences are quite great.

    What do British people think American people are like? The British think American people are very strange. They make a lot of noise and they laugh too loudly. They are rich, and they only think about money. But the British do say that American people are kind friendly people. They're happy to help you if you are in trouble.

    What do Americans think of the British? Well, they think the British are cold and very unfriendly. They are not interested in success or in making lots of money. They think British is the best country in the world. They look down on other countries. But Americans say that the British are quite hard workers. They are brave and honest. And in time of trouble they face difficulties happily.

    You can see that these ideas can cause misunderstanding between the British and Americans. But when American and British people become friends, they usually find things are not as bad as they expected.

    As businesses and governments have struggled to understand the so-called millennials—born between roughly 1980 and 2000—one frequent conclusion has been that they have a unique love of cities. A deep-seated preference for night life and subways, the thinking goes, has driven the revitalization of urban cores across the U.S. over the last decade-plus.

    But there's mounting evidence that millennials' love of cities was a passing fling(放纵). Millennials don't love cities any more than previous generations.

    The latest argument comes from Dowell Myers, an urban planning professor at USC. As they age, says Myers, millennials' presence in cities, will "be evaporating(蒸发) through our fingers, if we don't make some plans now." That's because millennials' preference for cities will fade as they start families and become more established in their careers.

    It's about more than aging, though. Demographer William Frey has been arguing for years that millennials have become stuck in cities by the 2008 downturn and the following slow recovery, with poor job prospects and declining wages making it harder for them to afford to buy homes in suburbia.

    Myers, too, says observers have confused young people's presence in cities with a preference for cities. Survey data shows that more millennials would like to be living in the suburbs than actually are. But the normal career and family cycles moving young people from cities into suburban houses have become, in Myers' words, "a plugged up drain."

    But unemployment has finally returned to healthy lows (though participation rates and wages are still largely stagnant), which Myers says should finally increase mobility for millennials.

    Other trends among millennials, supposedly matters of lifestyle preference, have already turned out to have been driven mostly by economics. What was once deemed their broad preference for public transit may have always been a now-reversing inability to afford cars. Even decades-long trends towards marrying later have been accentuated as today's young people struggle for financial stability.

    Investors are already taking the idea that millennials will return to old behavior patterns seriously, putting more money into auto manufacturers and developers. But urban lifestyles, up to and including trendy bars, aren't just hip—they're a part of what powers a city's economic engines, bringing people together to explore new ideas, create companies, and build careers.

    From the 1960s to the 1990s, we saw that suburbanization(城市郊区化)also means an economic and social hollowing out for cities. Now that the economic shackles are coming off today's young city residents, cities that want to stay vibrant(充满生机的) have to figure out how to convince them—and their growing families—to stick around.

    According to a British study presented to an international conference on smoking, within a few short years, more girls in Europe will be smokers than boys, for reasons experts still fail to understand.

    Anti-smoking activists (积极分子) at the second "Tobacco or Health" conference on the Canary Islands pointed out that while adults were giving up smoking in ever growing numbers, more and more young people were taking up the habit, especially girls.

    One 15-year-old in four is a regular smoker, according to a study made in 27 countries in Europe, the United States, Canada and Israel by Edinburgh University together with the World Health Organization.

    In Western Europe, girls were more likely than boys to smoke. In Germany and England, one third of the girls were smokers compared to one in four boys. In Eastern Europe, the girls "still fall behind" those in the Western Europe but were "catching up" quickly, said the study.

    The study dealt with the behaviour of 15-year-olds in seven European countries over a four-year period.

    The percentages of young women smoking went from 17 percent to 36 percent in Austria, from 17 percent to 28 percent in Norway, and from 21 percent to 28 percent in Hungary.

    Of the seven countries and regions studied (Austria, Finland, Hungary, Norway, Sweden, Switzerland and Wales), more girls than boys smoked in 1998, with the exception of Hungary.

    Most of the time, people wear hats to protect themselves from harsh weather conditions. Hats are also worn to show politeness and as signs of social position. But nowadays, hats, especially women's hats, are much more than that. More exactly, hats have changed into fashion and style symbols by many movie stars. What's more, people now consider many different features when choosing even a simple hat. Many designers point out that, when choosing the right hat, it's important to consider the color of your skin as well as your hair, your height, and the shape of your face.

    First of all, the color of the hat should match the color of your skin and hair. For instance, black hats should be avoided if you are dark skinned. If a purple hat is placed on top of red hair, one will look as attractive as a summer flower. Second, the height of the hat is also an important point. Tall women should not go for hats with tall crowns, just as short women should choose hats with upturned brims to give the look of height. Third, and most importantly, the shape of the face decides the kind of hat one should pick. A small, gentle hat that fits the head looks good on a small face. However, women with big, round faces should choose a different style.

As the saying goes, "Fine feathers make fine birds." A good hat can not only help your dress but also support your features, so why not choose the best possible one next time you want to be in public?

Over the years, electronic commerce or e-commerce has grown rapidly. The rise of e-commerce large enterprises such as Amazon and Alibaba in the mid-90s changed the face of the retail (零售) industry. E-commerce may be thought of as an open, global marketplace or a digital version of mail-order catalogue (目录). Nearly every imaginable product and service is available through e-commerce dealings these days.

Many young entrepreneurs have dived into the e-commerce world, ambitious and hoping to succeed. Some, like Mitchell Zvagelskiy. Zvagelskiy is the co-founder of Scale Online, a fast-growing startup in California and runs several e-commerce stores. Zvagelskiy and his business partner began opening online stores and building a team to grow them, allowing the stores to earn as much as $100.000＋ in monthly revenue. Zvagelskiy owes his success to teamwork and his willingness to seize opportunity.

"Being able to do this all by the age of 20 is something I didn't expect and would not be able to do if I constantly listened to other people and just went the typical college then job route," he said. "Life can change fast if you change fast."

Thanks to the rapid success of his YouTube channel, Mitchell has been able to not only make great profit from his companies, but help others in starting and growing their own e-commerce stores too. "My meaning of success arises from my relationships with other people," he said. "By focusing on building strong relationships with others, I'm able to partner up and work with like-minded individuals in finding market opportunities and solving whatever problems people are facing."
