The Peales were a famous family of American artists. Charles Willson Peale is best remembered for his portraits of leading figures of the American Revolution. He painted portraits of Franklin and Jefferson and over a dozen of George Washington. His life-size portrait of his sons Raphaelle and Titian was so realistic that George Washington reportedly once tipped his hat (脱帽打招呼) to the figures in the picture.

    Charles Willson Peale gave up painting in his middle age and devoted his life to the Peale museum, which he founded in Philadelphia. The world's first popular museum of art and natural science mainly covered paintings by Peale and his family as well as displays of animals in their natural settings Peale found the animals himself and found a method to make the exhibits more lifelike. The museum's most popular display was the skeleton (骷髅) of a huge, extinct elephant, which Peale unearthed on a New York farm in l801.

    Three of Peale's seventeen children were also famous artists. Raphaelle Peale often painted still lives of flowers, fruit, and cheese. His brother Rembrandt studied under his father and painted portraits of many famous people, including one of George Washington. Another brother, Rubens Peale, painted mostly landscapes and portraits.

    James Peale, the brother of Charles Willson Peale, specialized in miniatures (小画像). His daughter Sarah Miriam Peale was probably the first professional female portrait painter in America.

    The past two decades have seen astronomers' catalogue of planets expand over two hundred times, as new techniques and better telescopes have found more than 2,000 of them orbiting stars other than the sun. But in the solar system itself, the list of planets has actually shrunk, Pluto（冥王星）having been downgraded from that status in 2006. The number of the sun's planetary companions has thus fallen from nine to eight.

    Now, a pair of astronomers from the California Institute of Technology think they have evidence that will restore the sun's record to its previous value. Their analysis of objects orbiting in the Kuiper Belt（柯伊伯带）, a ring of frozen asteroids（小行星）that circle beyond the orbit of Neptune (and of which Pluto is now regarded as the largest member), suggests to them that something about ten times as massive as Earth has changed those orbits. If you knew where to look, this planet-sized object would be visible through a suitable telescope. And Konstanin Batygin and Michael Brown believe they do know.

As they write in the Astronomical journal, they have analyzed the orbits of Kuiper Belt objects and found six that behave in a peculiar way. As the diagram shows, the points of closest approach of these objects to the sun, known as their perihelia（近日点）, almost coincide. Moreover, these perihelia all lie near the ecliptic（黄道）—the plane of Earth's orbit and also, approximately, that of the other planets—while the objects' orbits are all angled at 30° below the ecliptic. The chance of all this being a coincidence, the two researchers estimate, is about seven in 100,000. If it is not a coincidence, it suggests the six objects have been guided into their orbits by the gravitational intervention of something much larger.

    A computer analysis Dr Batygin and Dr Brown performed suggests this something is a planet weighing 5-15 times as much as Earth, whose perihelion is on the opposite side of the sun from the cluster, and which thus orbits mainly on the other side of the solar system from the objects its orbit has affected. This planet's perihelion would be 200 times farther from the sun than Earth's, and the far end of its orbit might be as much as six times that distance away. This gives a search zone, and Dr Batygin and Dr Brown are using Subaru, a Japanese telescope, to perform that search.

    Given other demands on Subaru's time, it might take five years for this search to find (or not find) the hypothetical planet. But looking at some existing data from. The Widefield Infrared Survey Explore, a satellite, might also show it, if it is there to be seen.

    Ironically, it was Dr Brown as much as anyone who was responsible for Pluto's downgrading, for he discovered Eris, an object almost as big as Pluto, in 2005.

    That discovery did much to damage Pluto's planetary proof. By his own admission, he was skeptical that the anomalies he and Dr Batygin have investigated actually would point to the existence of a replacement ninth planet. He is a skeptic no longer. Whether he is actually right may soon become apparent.

    Anaya Elick was born without hands – she has stubs（残端）where most people's wrists begin.

    To hold a pencil, she must balance it between her wrists, then use her arms to push it along the page. But that didn't stop her from winning a national handwriting contest when she was in first grade.

    In the two years since, she has taken on greater challenges. Last week, she won another national handwriting contest, this one for cursive（草书）. And by all accounts from her teachers at Greenbrier Christian Academy, she has become an accomplished artist.

    Anaya isn't one to boast about her successes. She unwillingly says they make her proud but adds that they come from “lots of practice.”

    Her friends at school said, “She inspires everybody by what she does and how she does it” child to fail, and raising one who was born with a disability can heighten that protective instinct.

    Before Anaya was born, doctors knew about her condition, although not its cause. Other than having no hands, she is a regular 9-year-old girl.

    Anaya succeeds because she is not afraid to fail, Middleton said. The two began practicing cursive last year, when Anaya was in second grade. She struggled sometimes, because unlike traditional penmanship, which allows for breaks after each letter, cursive words are written straight through – and added effort for someone who must balance rather than hold the pencil.

    Middleton could see her daughter thinking through the challenge, figuring out how she could do better. She'd get frustrated at times, but she never hesitated to do things as often as it took to get them right.

    “I don't think I've ever heard Anaya say I can't do something,” Middleton said.

    That attitude carries over to her other interests.

    Recently, Anaya and her classmates sat in Cheryl Leader's art room, working on an exercise. The goal was to get them thinking about different concepts, like color combinations and how an image can be formed by fully coloring inside straight and diagonal lines.

    For many people, the “golden years” are a time to slow down and recall past achievements. Nola Ochs—a Guinness record holder as the world's oldest college graduate at the age of 95—saw age as an opportunity to take on new challenges and satisfy unfulfilled goals.

    Born in 1911 in Illinois, Nola always loved learning. She was a good student who graduated from high school in 1929 and began college via correspondence course（函授课程）from Fort Hays State University in Kansas. After getting the degree of the college, she taught in county schools for four years before marrying her husband, Vernon Ochs.

    Soon, the realities of farming stopped any thoughts of furthering her education, though Nola lived a good, full life on the farm, raising four sons. She always yearned to learn more about the world she lived in, but not until after Vernon died in 1972, did Nola consider resuming her formal education.

    “I just thought something off the farm would be fun,” Nola explained. “Really, I had no thought of ever graduating. For 10 years, I just took classes that were of interest to me, mostly history and composition. And then one of the professors came to me and told me if I would take college algebra, I would have enough credit hours to graduate. And I finally made it.”

    For most people, graduating at the age of 95 with a 3.7 GPA might be enough of an accomplishment, but not for Nola. In May 2010, at the age of 98, Nola Ochs received her master's degree, making her the oldest person to receive that distinction.

By the time Nola passed away in 2016, at the incredible age of 105, she had achieved her goal of writing a book about her life experiences. At one point in the process, when asked for her life advice, she said, “Buy the plane ticket!” She meant that people should take advantage of life's opportunities and not wait until tomorrow.

    People who have seen Trisha Seifried Woodall with her cats say that she has a magic touch. Most people don't know anyone who can order a cat to jump on a table, sit for two minutes, and then jump to the floor and walk backward.

    Ms. Seifried Woodall has taught her cats to do all these tricks -- and many more. At her training center. Got Pet-ential, cats learn tricks for TV and magazine ads. Some of her cats have appeared on bags of cat food.

    When Ms. Seifried Woodall gets a cat, she first learns what that cat likes and doesn't like. "Some cats like to stay close to the ground, so I'll teach them how to stand behind me, and walk with me," she says. "Other cats, like high places, so they'll learn how to jump on my bent knee and then safely leap to my shoulder."

    Ms. Seifried Woodall grew up in a family with many pets, and she was first paid to work with animals when she was 18. At a summer job at an amusement park, she learned how to train a few of the animals for performances. She continued to train and learn about animals for 20 years before starting her own animal-training center.

    Ms. Seifried Woodall is proud of the skills her cats have learned, but she is also proud that her center's cats are healthy and social. She believes her cats enjoy learning new tricks.

    In Ms. Seifried Woodall's experience, no breed (品种) of cat is easier to train than others. All of her cats came from shelters. They have become pets in her home.

    Like most animal trainers, Ms. Seifried Woodall uses a reward system. Cats that are successful during training get food or a new toy. A cat that doesn't enjoy eating or playing will probably not be interested in being trained. She never scolds (责骂) them. "Cats need a lot of encouragement when they are performing, she says." I say good job or that s right several times during a single minute."

    It's holiday season and time for shopping. There are a bunch of items on your shopping lists ranging from small gifts, toys and festive decorations to Christmas and New Year cards. What's your first reaction to products labeled "Made in China"? If you still tend to relate "Made in China" to poor quality, you need to update your ideas. China's ability to produce high-quality products has been recognized by a growing number of foreigners. It's a misunderstanding to associate low quality with "Made in China".

    Cameron Purdy, a Web user, says that China manufactures poor-quality products does not mean it cannot manufacture high-quality products. He explains that the poor-quality products one purchases in the US for example, are made in the quality that the American companies ask for. "The price that you pay for the product has no relationship to the cost of its manufacturing," suggested Purdy. For example, for an item priced at $20 in the US, the cost of manufacturing it paid by the American company is usually less than $1. To guarantee the room for profit, the Chinese co-manufacturer spends less than $1 to produce the item.

    Amanda Wu, who lives in Shanghai, noted that many top brands have manufacturing factories located in China, and the most convincing example of China's manufacturing quality is Apple products. On the back of the iPhone, one can find the product is Made in China—"Designed by Apple in California. Assembled (装备) in China. "Chinese and foreign Web users commented that some Chinese products with good reputations around the world are Haier, Lenovo, GREE, Huawei and China Railway High-speed.

    On the other hand, foreign misunderstandings can sometimes affect Chinese people's minds. For instance, when Chinese people travel abroad, some would still avoid buying products Made in China. It's time for the world to stop relating Made in China with low-quality products. Just remember, you get what you pay for.
