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.

    In the famous fairy tale, Snow White eats the Queen's apple and falls victim to a curse（诅咒）;in Shakespeare's novel, Romeo drinks the poison and dies; some ancient Chinese emperors took pellets（药丸）that contained mercury（水银）, believing that it would make them immortal, but they died afterward.

    Poison has long been an important ingredient in literature and history, and it seems to always be associated with evil, danger and death. But how much do you really know about poison?

    An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison.

    The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars（毛毛虫）, frogs and spiders. Golden poison frogs, for instance, aren't much bigger than a coin, but their skin is covered with a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans.

    "Poisons can be bad for some things," Michael Novacek, senior vice president of the museum, told NBC News. "Yet they can also be good for others."

    A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol.

    The benefits from natural poisons are not limited to just medicine. Believe it or not, many substances（物质）that we regularly ingest（摄入）-chili, coffee and chocolate-owe their special flavors or stimulating（提神的）effects to chemicals that plants make to poison insects.

    Homestay provides English language students with the opportunity to speak English outside the classroom and the experience of being part of a British home.

    What to Expect

    The host will provide accommodation and meals. Rooms will be cleaned and bedcovers changed at least once a week. You will be given the house key and the host is there to offer help and advice as well as to take an interest in your physical and mental health.

    Meal Plans Available

    Continental Breakfast

    Breakfast and Dinner

    Breakfast, Packed Lunch and Dinner

    It's important to note that few English families still provide a traditional cooked breakfast. Your accommodation includes Continental Breakfast which normally consists of fruit juice, cereal(谷物类食品), bread and tea or coffee. Cheese, fruit and cold meat are not normally part of a Continental Breakfast in England. Dinner usually consists of meat or fish with vegetables followed by dessert, fruit and coffee.

    Friends

    If you wish to invite a friend over to visit, you must first ask your host's permission. You have no right to entertain friends in a family home as some families feel it is an invasion of their privacy.

    Self-catering Accommodation in Private Homes

    Accommodation on a room-only basis includes a shared kitchen and bathroom facilities and often a main living room. This kind of accommodation offers an independent lifestyle and is more suitable for the long-stay student. However, it does not provide the same family atmosphere as an ordinary homestay and may not benefit those who need to practise English at home quite as much.

    If you are travelling in Britain, besides so many world-class things to see and do in London, planning a day trip away from it can also be worthwhile.

    Stonehenge

    Stonehenge consists of a group of huge standing stones. The 5,000-year-old stones are one of the world's biggest mysteries that no one has figured out yet. While exploring Stonehenge, you can imagine wildly and decide for yourself how the stones came to be there and why. Although you can't touch the stones, you can walk among them and feel the changes of seasons.

    Windsor

    Most people visit Windsor to see Windsor Castle, where the Queen spends most of her time. The castle itself could keep you busy for days. The best way to appreciate Windsor Castle is to approach via the Long Walk, a straight road where there are no cars, but you might see some deer.

    Oxford

    Oxford is best known for its world-famous university. The large student population keeps the atmosphere young and fresh, though there's no shortage of history if you want it. 30 colleges make up the university itself. A tour of the colleges is a must—Harry Potter fans will recognize various locations used in the movies.

    Bath

    Founded by the Romans, who used the area's springs to create a spa retreat（水疗中心）, Bath's now the best tourist attraction of Southwest England. Visitors never miss the Roman Bath Complex, which is divided into four main parts—the Bath House, the Sacred Spring, the Roman Temple and the museum, which displays fascinating finds from the historical ruins of the city.

    Traveling to Europe to see its famous monuments like the Eiffel Tower in Paris and the Colosseum(古罗马竞技场)in Rome, is not exactly the ideal vacation for kids. Fortunately, Europe has more to offer than lots of old churches and ancient history. You can enjoy some fun with your kids in the sun at some of the famous beaches of the continent.

    Mykonos, Greece

    The closer you get to the equator, the longer the beach season is, and Greece is wonderful for that. You can enjoy beautiful green water, public chairs and lovely umbrellas at the beaches in Mykonos.

    Dubrovnik, Croatia

    There's nothing more attractive than the beautiful beaches bordering Dubrovnik, Croatia's most beautiful city. It's surrounded by stone walls like a castle. It almost makes you feel like you're suntanning(晒黑皮肤)at Hogwarts, where the hero Harry Potter of the story is trained!

    Sicily, Italy

    Rabbit Beach on the island of Sicily offers shallow and crystal clear waters, making it a perfect beach for families with young children. And if you want to add interest to your experience, try snorkeling(徒手潜水).

    Nice, France

    Lined with palm trees and first-class hotels, the city of Nice, located on the French Riviera, offers a whole coastline of Mediterranean beaches. Because they're in the heart of the city, these beaches attract a large crowd. So if you're looking for something more private, you'll have to travel a few miles outside of the city center.

    Ribadeo, Spain

    At low tide, Playa de las Catedrales in Ribadeo, Spain is the perfect beach to take in the natural wonders without urban amusements like restaurants, bars or huge crowds. It boasts beautiful wild flowers and unique rock formations making it truly a picture worthy.

    After a morning hike in the Saneum HealingForest, 46-year-old firefighter Kang Byoung-wook has tea made from the bark of an elm tree, practices yoga (瑜伽), and makes a picture with dried flowers. He is one of 40 firefighters taking part in a three-day program, the aim of which is to offer "forest healing" (森林治愈); the firefighters all have posttraumatic stress disorder (创伤后应激障碍).

    Saneum is one of three official healing forests in South Korea. Soon there will be 34 more. South Koreans-many of whom suffer from work stress, digital addiction, and great academic pressure have accepted the medicalization of nature with great enthusiasm.

    There is increasing evidence that being outside in a pleasant natural environment is good for us. But how many of us get to enjoy nature regularly? Fewer and fewer, it seems. According to Lisa Nisbet, a psychology professor at Canada s Trent University, evidence for the benefits of nature is pouring in at a time when we are most disconnected from it.

    "We don't think of being outdoors as a way to increase happiness," says Nisbet. "We think other things will, like shopping or TV." But South Korea is starting to challenge this opinion.

    So what are some of the benefits of nature that Nisbet refers to? Being surrounded by nature has one obvious effect: It calms us and reduces our stress levels. This has been shown to lower blood pressure and heart rates.

    Another experiment conducted by psychologist Stephen Kaplan found that people who took a 50-minute walk in a park had better attention and short-term memory than those who took a walk along a city street.

    Perhaps what's more surprising is that nature may also make us more creative. David Strayer, a psychologist at the University of Utah, showed as much with a group of participants, who performed 50 percent better on creative problem-solving tasks after three days of wilderness backpacking.

    In fact, we may never know exactly what nature does to the brain. Something mysterious will always remain, and maybe that's as it should be.
