Leonardo da Vinci, one of the greatest thinkers in the world, began his career as an artist. Very little is known about Leonardo's early life. He was born in 1452 in the town of Vinci. As a boy, Leonardo showed a great interest in drawing, sculpting and observing nature.

    However, because Leonardo was born to parents who were not married to each other, he was barred from some studies and professions. He trained as an artist after moving to Florence with his father in the 1460s. It was an exciting time to be in Florence, one of the cultural capitals of Europe. Leonardo trained with one of the city's very successful artists, Andrea del Verrocchio. He was a painter, sculptor and gold worker. Verrocchio told his students that they needed to understand the body's bones and muscles when drawing people.

    Leonardo took the teacher's advice very seriously. He spent several periods of his life studying the human body by taking apart and examining dead bodies. While training as an artist, Leonardo also learned about and improved on relatively new painting methods at the time. One was the use of perspective(透视) to show depth. A method called “sfumato” helped to create a cloudy effect to suggest distance. “Chiaroscuro” is a method using light and shade as a painterly effect.

    Leonardo's first known portrait now hangs in the National Gallery in Washington, D. C. He made this painting of a young woman named Ginevra de' Benci around 1474. The woman has a pale face with dark hair. In the distance, Leonardo painted the Italian countryside.

    He soon received attention for his extraordinary artistic skills. Around 1475 he was asked to draw an angel in Verrocchio's painting “Baptism of Christ.” One story says that when Verrocchio saw Leonardo's addition to the painting, he was so amazed by his student's skill that he said he would never paint again.

    Yesterday I work up to the sound of music on my couch in my fifth floor apartment downtown. I couldn't possibly tell you what song was playing because my monologue of things to do that day had already begun. My thoughts ranged from what deals needed my attention today to what is the meaning of life. I felt as if it was going to be one of “those days”.

    After taking my son to school and glancing at my calendar, I noticed I was meeting my 85-year-old friend Harry. I remembered that we first met at a glass shop. I needed a new window and he was talking to the store clerk about his glass fireplace insert needing replacement. As I stood behind him in line, I found not how this old man funny and compassionate at the same time. By the end of his discussion I was so entertained that I decided to drum up a conversation with him. That was how our friendship began. I later learned this gentleman was originally from the mid-west and grew up on a farm. At 17, he joined the army and travelled the world until his late 40's. After the retirement, his wife passed away and now he lives alone in his three-bedroom home.

    We met at the appointed time. I promised to take him to lunch anywhere he wanted to go and he said, “I am a simple man; let's go to Taco Bell. Furthermore I don't need a pat on the back because it is only 18 inches away from a kick in the rear.” We both laughed as we got into the car.

    As we pulled into the parking lot of Taco Bell, Harry jumped out of the car and told me, “I have to go into the donut(甜甜圈) shop next door before going to Taco Bell.” Of course I agreed and in we went. He immediately walked in and began having a joke with the owner of the shop in his fashion. They bantered as she gave him a dozen donuts and off we went. I couldn't help but ask him, “What are the donuts for?” He quickly replied, “You will soon see.”

    As we opened the door to Taco Bell, the line was very long. It was lunch time. People were on their cell phones. Babies were crying and the waiters looked stressed and burnt out. Harry and I were waiting in line chatting about nothing until we reached the front of the line. As he walked to the counter, all the waiters began smiling. He placed the box of donuts on the counter and said, “These are for you and other staff.” Instantly, the mood in the restaurant changed. This single act of kindness made the customers, the waiters, the kids and even me take a look internally and ask: when was the last time we did something nice for a stranger?

    What was most amazing to me was earlier that morning I wasn't thrilled with my life. It felt like it was just another day. Watching this gentleman spend 6 dollars on donuts and provide them for the staff in a packed restaurant at the lunch rush hour changed my outlook on life. If you don't believe me, try it yourself. Take the approach in life that you make an effort to do the little things in order to make people feel appreciated on a daily basis. You will see that your life will be better and you will have less of “those days” I was talking about earlier in this article.

If you're secretly worried about your smart phone addiction, then the new NoPhone might be just the thing you need. It looks and feels exactly like a smart phone, but it does nothing. It's just a piece of plastic that you can carry around in your hand to fool yourself.

Dutch designer Ingmar Larsen came up with the idea as a joke along with his two friends. To their great surprise, the idea received a lot of attention online and people from all over the world started placing requests for NoPhones of their own. So that's when the three friends decided to turn to collecting enough fund for mass production.

    NoPhone is currently a prototype (模型) that will cost only $12 once it hits the market It is 5.5 inches high, 2.6 inches wide and 0.29 inches thick, bringing it quite close to the latest smart phones on the market. It is described as “battery free”, “no upgrades necessary,” “shatter-proof (抗震)”, “waterproof” and “an alternative to constant hand-to-phone contact that allows you to stay connected with the real world.”

“Phone addiction is everywhere,” the designers insist. “It's ruining your dates. It's distracting you at concerts. It's blocking sidewalks. Now, there is a real solution. With a thin, light and completely wireless design, the NoPhone acts as a substitute to any smart mobile device, enabling you to always have a phone to hold without giving up potential engagement with your direct environment.”

If you're interested in NoPhone, but concerned about not being able to take selfies (自拍) anymore. Don't feel upset. The makers do have an upgrade at no extra charge—the mirror sticker. That way, they say, you can enjoy “real-time” selfies with your friends when they're standing right behind you.

    Millions of TripAdvisor users voted New York, Chicago, Charleston and Las Vegas as the top four travel cities in the United States.

    New York City

    More than 50 million people visit New York City every year. The five boroughs（行政区）－or regions of New York have some of the most easily recognized attractions in the world. Visitors whose things are tight can take a free boat from Manhattan to Staten Island for a great view of the Statue of Liberty and the Manhattan skyline.

   Chicago, Illinois

    America's third-largest city offers world-class museums, great food, sporting events and symbolic architecture－including Willis Tower, America's tallest building. But what places the Midwest city above others is comedy. It's well-known for comedy shows. The Second City theater is where many famous comedians get their start, including Mike Meyers and Tina Fey.

    Charleston, South Carolina

    Some say Charleston is one of the most beautiful and historic places in the United States. The coastal（沿海的）city has a very rich history. The Civil War began at its waterfront, at Fort Sumter, which visitors can explore. But present-day Charleston has a lot to offer, too. Conde Nast Traveler voted it the number one U. S. city, for its beautiful architecture, food, and friendly people.

    Las Vegas, Nevada

    The desert city of Las Vegas is known around the world for its casinos（娱乐场）and bright lights. Visitors stay at world-class hotels, eat at top chefs' restaurants, and usually see a spectacular show or concert.

    After two years of careful consideration, Robert McCrum has reached a conclusion on his selection of the 100 greatest novels written in English. Take a look at a few in his list:

    The Pilgrim's Progress by John Banyan (1678)

    A story of a man in search of truth told with the simple clarity and beauty of Bunyan's prose makes this an English classic.

    Robinson Crusoe by Daniel Defoe (1719)

    By the end of the 19th century, no book in English literary history had enjoyed more editions and translations. This world-famous novel is a complex literature that one cannot resist.

    Gulliver's Travels by Jonathan Swift (1726)

    A great work that's been repeatedly printed, Jonathan Swift's Gulliver's Travels comes third in our list of the best novels written in English.

    Clarissa by Samuel Richardson (1748)

    Clarissa is a tragic heroine, pressured by her dishonorable family to marry a wealthy man she dislikes, in the book that Samuel Johnson described as “the first book in the world that shows the knowledge about the human heart”.

    Tom Jones by Henry Fielding (1749)

    Tom Jones is a classic English novel that gets the spirit of its age and whose characters are well-known since they have come to represent the society at that time.

    Emma by Jane Austen (1816)

    Jane Austen's Emma is her most outstanding work, mixing the best parts of her early books with a deep sense of feelings.

    The Narrative of Arthur Gordon Pym of Nantucket by Edgar Allan Poe (1838)

    Edgar Allan Poe's only novel—a classic adventure story with supernatural elements—has fascinated and influenced generations of writers.

    The British are known for their sense of humour. However, it is often difficult for foreigners to understand their jokes. The main point to remember is that the British often use understatement.

    Understatement means saying less than you think or feel. For example, if someone gets very wet in a shower of rain, he might say, "It's a little damp (潮湿的) outside." Or, if someone is very impolite and shouts at another person, someone else might say, "She isn't exactly friendly." Understatement is often used in unpleasant situation or to make another person look silly. Understatement plays an important part in British humour.

    Another key to understanding British humour is that the British like to make fun of themselves as well as others. They often laugh about the silly and unpleasant things that happen to our everyday life when someone accidentally falls over in the street. They also like to make jokes about people from different classes of society. They like to make jokes about their accents, the way they dress and the way they behave. What's more, the British love to watch comedies about people who do not know how to behave in society. The comedy series Mr. Bean is a good example of this kind of humour. Mr. Bean is the character created by British actor Rowan Atkinson in 1990.

    Mr. Bean doesn't talk often, and instead he uses his body movements and facial expressions to make people laugh. Perhaps what makes Mr. Bean so funny is that he does things that adults in the real world cannot do. Mr. Bean is popular in many countries around the world because you do not have to speak English to understand the humour. Because of this, many people have become familiar with the British sense of humour.
