Have you ever noticed what happens to an idea once you express it?Just talking about it or writing it down causes you to make it clear in your own mind.How can you use this to increase your brain power?Start writing.

    By putting thoughts into words,you are telling yourself the logic behind what you think,feel,or only partly understand.Often,explaining a thought is the process of understanding.In other words,you increase your brain power by exercising your “explain power”.

    Another benefit of writing is that it helps you remember.Many,if not most,highly productive people are always taking notes.You can try keeping it all in your head,but if you keep a journal of your ideas,the next time you're working on a big project,you'll probably have more success.

    Want to understand a topic?Write a book about it.That's an extreme example,but if you are learning something new,write a letter to a friend about it,and you will understand it better.Want to invent something?Write an explanation of the problem—why you want to solve it,and why it is worth solving,and you're halfway there.

    Writers don't always write because they clearly understand something beforehand.Often,they write about something because they want to understand it.You can do the same.Writing will help bring you to an understanding. Give it a try.

    Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws(爪)on its wings when young .They build their homes about 4.6m above the river ,an important feature(特征)for the safety of the young. It is called the hoatzin.

    In appearance, the birds of both sexes look very much alike with brown on the back and cream and red on the underside .The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young.

    Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip .Using these four claws ,together with the beak(喙),they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws.

    During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.

    Now many young people are traveling around the world on their own, not because they have no one to travel with, but because they prefer to go alone.

    Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.

    In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen, it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.

    Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website, The Aussie Nomad, to document his adventures. He says he wished he had traveled alone earlier. “The people you meet, the places you visit, or the things you do, everything is up to you and it forces you to grow as a person,” said the 30-year-old man.

    Richardson describes traveling alone like “a shot in the arm”, which “makes you a more confident person that is ready to deal with anything”. He said, “The feeling of having overcome something on my own is a major part of what drives me each day when I'm dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”

    The great 19^thcentury explorer John Muir once said, “Only by going alone in silence can one truly get into the heart of the wilderness.”

    Earthquakes are something that people fear. There are some places that have few or no earthquakes. Most places in the world, however, have them regularly. Countries that have a lot of earthquakes are usually quite mountainous.

    The most talked about earthquake in the United States was in San Francisco in 1906. Over 700 people died in it. The strongest one in North America was in 1964. It happened in Alaska.

    Strong earthquakes are not always the ones that kill the most people. In 1755, one of the strongest earthquakes ever recorded was felt in Portugal. Around 2,000 people died.

    In 1923, a very strong earthquake hit Tokyo, Yokohama area of Japan. A hundred and forty thousand people died. Most of them died in fires which followed the earthquake.

    One of the worst earthquakes ever was in China in 2008. It killed a large number of people. The worst earthquake ever reported was also in China, in which 400,000 people were killed or injured. This earthquake happened in 1556.

    Earthquakes worry people a lot. The reason is that we often do not know when they are coming. People cannot prepare for earthquakes.

    It was the beginning of 2011. I had just finished filming the first season of Game of Thrones(《权利的游戏》). With almost no professional experience, I had been given the role of Daenerys Targaryen. The show was so successful that young girls would dress themselves up as Daenerys for Halloween.

    And yet, terrified of the attention, terrified of trying to make good on the faith that the creators had put in me, I worked much harder.

    On the morning of February 11, 2011, I was getting dressed in a gym when I started to feel a bad headache. I was so exhausted that I could barely put on my sneakers. I tried to ignore the pain, but I couldn't. I reached the toilet and sank to my knees. A woman came to help me. Then everything became unclear. I only remember the sound of an ambulance.

    That operation lasted three hours. When I woke, the pain was unbearable. After four days, they moved me out of the I.C.U. (重症监护室). But one day when a nurse asked me, as part of a series of cognitive (认知的) exercises, " What's your name?", I couldn't remember my name and I felt terrified: I am an actor; I need to remember my lines. Now, I couldn't recall my name.

    The phenomenon is called aphasia. Then I was sent back to the I.C.U. and, after about a week, I was able to speak and know my name. And I was also aware that there were people in the beds around me who didn't make it out of the I.C.U. I was continually reminded of just how fortunate I was.

    I rarely gave a thought to my health. Nearly all I thought about was acting. I thought of myself as healthy. Once in a while, I would get dizzy. When I was fourteen, I had a migraine (偏头痛) that kept me in bed for a couple of days. But it all seemed manageable — part of the stress of being an actor. Now I think I might have been experiencing warning signs of what was to come.

    Anyway, there is something pleasant about coming to the end of Thrones. And I'm so happy to be here to see the beginning of whatever comes next.

A grocery store in Ann Arbor, Michigan opened on Tuesday to the public. This is an artist's uneatable creation. The Plastic Bag Store presents shelves filled with items such as meat, eggs, cakes and so on, all of which are made from single-use plastics taken from streets and garbage.

The store at times during the day will be transformed into a stage for a series of short films in which puppetry(木偶戏表演), shadow play, and handmade sets are used to tell a story of how the overabundance of plastic waste we leave behind might be misinterpreted by future generations—and how what we value least may become our most lasting "cultural legacy (遗产)".

Theater and film director Robin Frohardt is the creative driving force behind the Plastic Bag Store. "I got the idea many years ago after watching someone bag and double-bag and triple-bag my groceries," Frohardt said on Tuesday. "I just was sort of struck by how much packaging was involved in our everyday lives. And it just seemed so unreasonable. I just thought, maybe I could set up a project to change it." Combining a real-life supermarket with film experience, Frohardt planned to use art and humor to question our culture of consumption and convenience and to show one of the greatest problems of our planet.

Plastic bags are created by fossil (化石) fuels and often end up as waste in landfills and the ocean. Americans throw away 100 billion plastic grocery bags per year. She hopes that she can continue to tour with the project and bring it to different communities. "My dream would be that this project will become unnecessary one day," said Frohardt.

 "Frohardt's work reminds us, with humor, to think not just about the next two weeks, but also about the next two decades and the next two centuries. What will remain hundreds of years later? We hope that our legacy will be plays rather than piles of plastics," said Tim Tompkins, President of Times Square Alliance.
