    To us, it seems so natural to put up an umbrella to keep the water off when it rains. But in fact the umbrella was not invented as protection against the rain. Its first use was as a shade against the sun.

    Nobody knew who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, back in the eleventh century BC.

    We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its uses：it became a symbol of honor and power. In the Far East in ancient times, the umbrella was allowed to be used only by those in high office or by royal people such as the kings or queens.

    In Europe, the Greeks were the first to use the umbrella as a sunshade. The umbrella was in common use in ancient Greece, but it is believed that the first people in Europe to use the umbrella as protection against the rain were the ancient Romans. During the middle ages in Europe, the use of the umbrella almost disappeared. Then it appeared again in Italy in the late sixteenth century. And again it became a symbol of power.

    Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn't until the twentieth century that the umbrellas for women began to be made in all kinds of colors.

When I ask her what she is doing, she tells me that she is busy with her schoolwork and she needs to look for information on the Internet. But it's not true. A few days ago, I discovered that she was surfing the Internet and visiting lots of different websites. She spends most of her time with strangers on QQ. This is very worrying

Apps（应用软件）are becoming increasingly popular nowadays, and for good reason. They can help you out in just about every area of your life, whether it's  fit, communicating with friends, or even learning a language. However, you need to know how to use them to really benefit. Here's what you should think about before downloading an app for language learning.

•Learn from different sources（most just apps）

Any experienced language learner will tell you that the beauty of mastering a foreign language is the world which it up to you. This is a world of different sources of information, from newspapers and books to TV, radio, music and even real people. Would you limit to one medium in your native language？Probably not, so why do so in your new language？

•Set up your purpose and plan your

Do you want to be fluent in weeks or are you in it for the brain training？The good apps are to help you fit your studies according to your timetable. These apps encourage habit building, because a habit ensures your safe and regular return.

•Make it social

I don't mean posting your progress online. I mean social for real. I owe the speed of progress I made in to the support from Jim, my partner from Italy in study time. Find a friend to accompany you. Take an evening class. Borrow a book. Buy a book. Book a week away and attend a language school.  Just don't forget  your phone !

If I may speak sincerely, the combination（结合）of app, language school, Jim, evenings out, and a   book or two proved rather useful.

    The ability to think creatively is not a gift everyone has naturally, so it must be developed as a skill. Here are some tips to help you develop creative and critical（批判性）thinking abilities.

    Step outside your comfort area

    Stepping outside of your comfort area is an easy way to expand your creative and critical thinking skills. This can mean reading a book or an article that is completely unrelated to any previous studies, or even having a difficult conversation with someone you're close to. We all grow from discomfort.

Stay healthy

    Your mind is in the best shape when your body is. Exercise and a healthy diet can clear the mind and allow for creativity. Some people are easily distracted（分心）by a messy office or a dark room. Most people are the most awake when they are in clean, healthy, and organized environments.

    This is a common skill used by journalists and writers suffering from writer's block. It's an easy tool to pet the creative juices flowing. Open up your computer, or take a notebook and pen and just start writing. Just let your mind take you wherever it wants to go.

    Take a breather

    Everyone may reach points where they get stuck on an idea and can't get past it. Don't let this discourage you, and don't blame yourself Go outside for some fresh air, take a walk, eat meal, or call a friend. Distraction can be very rewarding.

    As teenagers, changing the world does not only mean finding a cure for cancer, or finding the origin（起源）of humanity, but recycling a piece of paper as well. Going Green is a practical way that teenagers can have a real and meaningful influence in the world. The following are three simple ways teenagers can go green and change the world.

    Recycle

    According to an online article, 63 million newspapers go out to street vendors（摊贩）or local paper boys every day and of those 44 million are thrown away. Recycling the Sunday newspapers alone we could save half a million trees a week. The age of technology creates new phones, iPods, or new computers. Many people will stand in line for hours to get their hands on the new piece of technology,  but what happens with the old ones？ Nothing. According to Earth 911, about 75% of the old devices（设备）are thrown in the back of a drawer collecting dust.

    Go vegetarian（素食主义）one day a week

    Here are some amazing facts on going vegetarian for only one day. According to Noam Mohr, a physicist at the New York University, the United States would save 100 billion gallons of water which is enough to offer all homes in New England for about 4 months. The Environmental Defense concludes with the most interesting fact： if the whole population gives up one meal of chicken, the amount of carbon dioxide accumulated（累积的）would be the same amount if more than half a million cars were taken off U. S. roads. So giving up just one day of eating meat is worth the advantages it could bring.

    Don't drink too much bottled water

    There is a common idea that bottled water is healthier than regular tap water. However, 25% of bottled water comes from regular tap water which goes through a filter （过滤）. Bottled water companies do not need to list where they got the water from, how they clean the water, or what chemicals their plastic water bottles have. Plastic bottles do not get recycled 90% of the time which results in 1. 5 million tons of plastic in landfills which are not easy to decompose （分解）. In fact, after considering that bottled water and tap water have few differences, people should use more reusable water bottles.

    Just keep in mind what Margaret Mead once said, "Never doubt that a small group of thoughtful and committed （坚定的） citizens can change the world. Indeed, it's the only thing that ever has. "
