Do you want to take time to get in touch with yourself, your feelings, your dreams, and a good, healthy life? Here are some tips:

    {#blank#}1{#/blank#} Sometimes it seems as if our culture has begun to view the need for sleep as a sign of weakness. But your body was genetically(基因地) programmed to spend a third of its life on sleep, and this affects thinking, memory, growth, your immune(免疫的) system and even your weight.

    Begin the day in thankfulness. {#blank#}2{#/blank#} Name each person and hold them in your thoughts. The sense of thankfulness you experience will set a peaceful tone for the entire day, and reduce a day's stress that can lead to sleeplessness that night.

    Strike a balance. {#blank#}3{#/blank#} Think about tai chi, prayer, yoga(瑜伽)—any daily activity that allows you to develop a peaceful center and a sense of balance.

    Play with friends. The "tend and be friend studies", as they are called, conducted by UCLA researcher, Shelly Taylor, Ph.D. indicate that when women are stressed, they tend to their children and play with other women. {#blank#}4{#/blank#}

    Use guided imagination. {#blank#}5{#/blank#} The tone of your voice, pacing, music, and pictures will persuade your nervous system that it's time to calm down.

    Rodney Smith, Jr. started mowing the lawns (割草坪) in Huntsville, Alabama last fall. He used his time between classes at Alabama A&M to reach a goal of mowing 100 yards before winter. Smith has been cutting grass for free to help single moms, the elderly, and the disabled, while teaching the local youth the values that can turn boys into men. “I'm doing something positive. I want boys to follow me and be better than me,” he wrote on his Facebook page.

    Rodney is from Bermuda. He says people there help each other and are always friendly. “That's what drives me to help people.”

    In May this year, he was getting ready to launch his mowing service for the summer when he heard about a 93-year-old woman trying to cut grass by herself. Smith and a friend showed up to do the job for her.

    In November, a local TV station gave him $300, calling it a special gift for his good work. After he received the money, he used it to create the non-profit(非盈利的) service group, Raising Men Lawn Care Service. He also started a page to collect money to buy lawn equipment and other things—including T-shirts with special logos.

    After I read about Rodney's story, I told my friends about him. We also planned to mow lawns for single moms, the elderly and disabled in our neighborhood. And I hope more and more young people will join Rodney's service group—Raising Men Lawn Care Service.

    The female dog, who Leonard appropriately named Gobi, joined Leonard on the second day of the annual 4 Deserts Race Series and ran side-by-side with him for 77 miles. Leonard noticed Gobi running with 101 runners during the first day, but on the second day, Gobi was on the start line, looking up at him. "This was the first contact I had with her and as I ran off the line I noticed her by my side," he said. "I didn't speak much to her that day, but at the finish line she followed me into the tent and we slept next to each other. That was it then."

    Leonard shared his sleeping space, water and food with his small companion during the race. He even lent her a hand when needed. "I carried her across rivers that she could not cross on her own," he wrote on his Crowdfunder page.

    After the race, it was clear to Leonard that he had developed a special bond with the pup and started researching ways to get Gobi to the UK. He learned that it would take four months for Gobi to be medically checked and cleared for entry, all of which will cost $6,560 USD, an amount that has been surpassed(超过) due to a successful Crowdfunder campaign that raised $13,330 USD.

    My favourite book is The Adventure of Tom Sawyer by Mark Twain. Tom lives with his aunt Polly in a quiet street of St. Petersburg, Missouri. He's a lively and clever young boy, and he finds himself in many exciting adventures. He runs away with his two friends, Huck Finn and Joe, to an island in the middle of the Mississippi River for several days. With Huck he goes looking for treasure, with Becky he gets lost in a cave. And finally, they find a box of gold.

    My favourite scene in the book is when everyone thinks Tom is dead. He decides to go to his own funeral. He hides and watches for a time and then suddenly he appears. Everyone is astonished to see him but they're also pleased to see him alive.

    Tom is the hero of the story, but there are other important characters. Huck is an outsider and everyone is afraid of him. Becky is pretty with fair hair, Joe is Tom's best friend. And Injun Joe is the bad man of the story.

    The theme of the story is about children growing up. It describes how strangers are seen in small towns of America. Finally, it talks about freedom, social rules and how people are punished for bad behaviour.

    Why do I think The Adventure of Tom Sawyer is a great book? Mark Twain wrote the story in 1876, but it's still read and loved by people all over the world today. And although it's only a story, Twain wrote it in the everyday English of the southern states of America in the 19th century, so it sounds very real. Today it's thought to be one of the greatest books in American literature. Go on—read it! I know you'll enjoy it, too.

    It's common knowledge that the woman in Leonardo da Vinci's most famous painting seems to look back at observers, following them with her eyes no matter where they stand in the room. But this common knowledge turns out wrong.

    A new study finds that the woman in the painting is actually looking out at an angle that's 15.4 degrees off to the observer's right­well outside of the range that people normally believe when they think someone is looking right at them. In other words, said the study author, Horstmann, "She's not looking at you." This is somewhat ironic, because the entire phenomenon of a person's gaze (凝视) in a photograph or painting seeming to follow the viewer is called the "Mona Lisa effect" . That effect is absolutely real, Horstmann said. If a person is illustrated or photographed looking straight ahead, even people viewing the portrait from an angle will feel they are being looked at. As long as the angle of the person's gaze is no more than about 5 degrees off to either side, the Mona Lisa effect occurs.

    This is important for human interaction with on-screen characters. If you want someone off to the right side of a room to feel that a person on-screen is looking at him or her, you don't cut the gaze of the character to that side­surprisingly, doing so would make an observer feel like the character isn't looking at anyone in the room at all. Instead, you keep the gaze straight ahead.

    Horstmann and his co-author were studying this effect for its application in the creation of artificial-intelligence avatars(虚拟头像) when Horstmann took a long look at the "Mona Lisa" and realized she wasn't looking at him.

    To make sure it wasn't just him, the researchers asked 24 people to view images of the "Mona Lisa" on a computer screen. They set a ruler between the viewer and the screen and asked the participants to note which number on the ruler intersected Mona Lisa's gaze. To calculate the angle of Mona Lisa's gaze as she looked at the viewer, they moved the ruler farther from or closer to the screen during the study. Consistently, the researchers found, participants judged that the woman in the "Mona Lisa" portrait was not looking straight at them, but slightly off to their right.

    So why do people repeat the belief that her eyes seem to follow the viewer? Horstmann isn't sure. It's possible, he said, that people have the desire to be looked at, so they think the woman is looking straight at them. Or maybe the people who first coined the term "Mona Lisa effect" just thought it was a cool name.

    At 1,345 meters above sea level, Ben Nevis is not the world's most difficult mountain to climb. But things get considerably tricky if instead of hiking shoes you put on a pair of 5-inch high heels, especially if you're a guy. One English teenager recently proved that it was not impossible.

    Ben Conway, a 19-year-old art student from London, recently took up the challenge as a way to stand out in an application for a scholarship for the School of Communication Arts in Brixton. He started his unusual high-heel climb at 8 a.m., on June 27, and was joined by Callum MacKenzie Allen, a friend from his art foundation year, who videotaped the whole thing for a two-minute video that was used as his application project. The whole climb took five hours and wasn't the smoothest experience.

    Halfway up Ben Nevis, one of his shoes broke, so he had to tape the shoes to his feet to make sure they stayed on. The weather didn't make it easy for him either, as he claimed that it rained pretty much the whole time, and he had to go against 40 to 50 miles an hour winds. Due to these difficult conditions, Ben and his friend had to turn back after reaching 900 meters up the mountain.

    Besides providing a unique art school application project, the high-heel climb also allowed the 19-year-old to raise some money for worthy causes (事业), like Sal's Shoes, which provides footwear for barefoot children around the world.

    "Raising money for charity brings happiness to people's lives and if I can do something ridiculous and bring someone happiness, then that's what it's all about." Ben said.
