    Scientists say we are all born with a knack for mathematics. Every time we scan the cafeteria for a table that will fit all of our friends, we're exercising the ancient estimation center in our brain.

    Stanislas Dehaene was the first researcher to show that this part of the brain exists. In 1989, he met Mr. N who had suffered a serious brain injury. Mr. N couldn't recognize the number 5, or add 2 and 2. But he still knew that there are “about 50 minutes” in an hour. Dehaene drew an important conclusion from his case: there must be two separate mathematical areas in our brains. One area is responsible for the math we learn in school, and the other judges approximate amounts.

    So what does the brain's estimation center do for us? Harvard University researcher Elizabeth Spelke has spent a lot of time posing math problems to preschoolers. When he asks 5-year-olds to solve a problem like 21+30, they can't do it. But he has also asked them questions such as, “Sarah has 21 candles and gets 30 more. John has 34 candles. Who has more candles?” It turns out preschoolers are great at solving questions like that. Before they've learned how to do math with numerals and symbols, their brains' approximation centers are already hard at work.

    After we learn symbolic math, do we still have any use for our inborn math sense? Justin Halberda at Johns Hopkins University gave us an answer in his study. He challenged a group of 14-year-olds with an approximation test: The kids stared at a computer screen and saw groups of yellow and blue dots flash by, too quickly to count. Then they had to say whether there had been more blue dots or yellow dots. The researchers found that most were able to answer correctly when there were 25 yellow dots and 10 blue ones. When the groups were closer in size, 11 yellow dots and 10 blue ones, fewer kids answered correctly.

    The big surprise in this study came when the researcher compared the kids' approximation test scores to their scores on standardized math tests. He found that kids who did better on the flashing dot test had better standardized test scores, and vice versa (反之亦然). It seems that, far from being irrelevant, your math sense might predict your ability at formal math.

(1)、From the first two studies, we can learn that estimation center ________.
A、is divided into two separate mathematical areas B、can help figure out numerals and symbols problems C、functions independently in both kids' and adults' brains D、works better when symbolic parts are injured or undergrown
(2)、What most surprised Justin in the study of 14-year-olds?
A、The variety of math abilities in different students. B、The link between technology skills and estimation skills. C、The difficulty of the task as the number of dots increased. D、The connection between estimation skills and formal math ability.
(3)、What could be the best title for the passage?
A、Born with a Sense of Math B、Go beyond What You Can Learn C、Symbolic Math and Estimation Math D、Our Brain一a Born Mathematician

    At 80 years old,scientist Jane Goodall continues to enjoy the joy of discovery.“Trees can communicate with each other,” she said during her Nov.16,2014 China visit to celebrate the 20th anniversary of the China establishment of her youth organization Roots & Shoots,which has grown to more than 600 branches in the country among 150,000 active groups globally.

    Jane Goodall still travels 300 days a year in all around the world and says she absorbs energy from the inspired people she meets in each country.The elderly activist and the youth take inspiration from each other.

    On Nov.16,2014,she visited the project of Roots & Shoots which was set up in Beijing.“She thought our project was great,” says 16-year-old Beijing Experimental High School student Qi Zhengyang,whose group helps protect a wetlands in the suburbs of Beijing.“She said we're doing a good job.She paid attention to us.”

    Jane Goodall plans to continue to set up Roots & Shoots branches as many as possible throughout the world.“I'll go on as long as I can,” she says.“I hope I maintain physical health as long as possible because there's so much to do.” Her aspiration for the organization in China is to expand in rural areas.Most branches are in big cities as Beijing and Shanghai.

    It was publishing her findings about chimpanzees (My Friends the Wild Chimpanzees)  more than half a century ago that made Jane Goodall a household name in the world.She was named United Nations Messenger of Peace in 2002.

    Some of the members in Roots & Shoots realize Goodall is 80 and has already considered who'll lead the movement once she's gone.“It can be all of us,” she says.“A group is stronger than one person.We can do more working together.”

    Taylor Swift was born on December 13, 1989, in Wyomissing, Pennsylvania. Swift's family ran a farm. “I had her sitting on a small horse when she was nine months old,” said Swift's mother. “If my dream had gone well, she'd be in a horse show right now.” The only obvious forerunner (先驱) of Swift's musical talent was her grandmother, an opera singer.

    That talent showed itself early: when the family went to see a Disney musical film, Swift would come out of the theater singing all the songs correctly. At the age of 11, she sang “The Star-Spangled Banner” at a Philadelphia 76ers game. The experiences during her pre-teen years encouraged the creativity to go with Swift's talent. As a child, she attended the academically competitive Wyndcroft School in Pottstown, but then switched to public schools in Wyomissing. Although it was her hometown, she didn't know any of her classmates, and she was terrified. Swift began to understand the storytelling feature of country songs, and put her feelings into songs of her own.

    One of her future hits, “The Outside”, was written when she was only 12. “I wrote that about the scariest feeling I've ever felt: going to school, looking at those faces, and not knowing who you're gonna talk to that day,” she said. “In the music, I could never feel the kind of rejection (拒绝) that I felt in middle school.” Swift's parents quickly realized that they had someone special on their hands. They sold their farm when she was 13 and moved the family to Hendersonville, Tennessee.

    Swift had the ability, above all, to put feelings into words with accuracy (准确) far beyond her years. In “Our Song” she wrote, “Our song is the slamming screen door, going out late, tapping on your window.” In the summer of 2006, “Tim McGraw” came out, and almost from the beginning the 16-year-old Taylor Swift was a star.

    Teary-Eyed Stories from Strangers

    The Man at the Market

    When the supermarket clerk summed up my groceries, it was $12 over what I had on me. I began to remove items from the bags, when another shopper handed me a $20 bill. “Please don't put yourself out,” I told him.

     “Let me tell you a story,” he said. “My mother is in hospital with cancer. I visit her every day and bring her flowers. I went this morning, and she got mad at me for spending my money on more flowers. She demanded that I do something else with that money. So, here, please accept this. It is my mother's flowers.”

    A Family's Food Angel

    Since my mother lost her job, our family troubled new worries: no income, the same bills, and no way to afford groceries. It was around this time that she started finding boxes of food outside our door every morning. This went on for months, until she was able to land a job. We never did find out who it was and who left the groceries for us, but they truly saved our lives.

    Seven Miles For Me

    Leaving a store, I returned to my car only to find that I'd locked my keys and cell phone inside. A teenager riding his bike saw me kick a tire and say a few choice words. “What's wrong?” he asked.

    I explained my situation. “But even if I could call my wife,” I said, “she can't bring me her car key, since this is our only car.” He handed me his cell phone. “Call your wife and tell her I'm coming to get her key.”

    “That's seven miles round trip.”

    “Don't worry about it.”

    An hour later, he returned with the key. I offered him some money, but he refused. “Let's just say I needed the exercise,” he said. Then, like a cowboy in the movies, he rode off into the sunset.

    Breaking Bread

    Last December, before work, I stopped at a deli (熟食店) and ordered an everything bagel with cream cheese. It was toasty warm, and I couldn't wait to dig in. But as I left the store, I noticed an older indigent gentleman sitting at the bus stop. Knowing it would probably be his only warm meal of the day, I gave him the bagel.

    But all was not lost for me. Another customer from the deli offered me half of her bagel. I was so delighted because I realized that in one way or another, we are all looked after.

    Alex Elman runs a big business—something hard to imagine after she lost her sight in her twenties. But Elman says that losing her sight helped her focus on finding success.

    Elman's father planted a hillside vineyard(葡萄园)in western Massachusetts in 1981. It's where Elman spent the darkest period of her life. When she was 27 years old, she went blind as a result of diabetes(糖尿病) 17 years ago. She recalled,“I hid in my home. I hid in the place,to me, that was the safest place in the world.”

    However, she found a new way forward.

    Elman is the founder of Alex Elman Wines, a growing competitor of organic wines from all around the world: Chianti from Italy, Torrontes from Argentina.

    Elman's isn't solitary in her work. Instead, she has a good assistant, a guide dog named Hanley. Hanley is something of a professional wine taster and travels to all of the wine factories that Elman runs, from South America to Europe.

    At first, Elman wouldn't accept a guide dog. Now it's hard to imagine her life, or her business, without him. She said, "When someone tells me something is organic and I don't really believe it because I taste something funny on it, m put it in front of his face and if he likes the wine, he'll actually go in and sniff it. If if s not right, he'll turn his head away. That's how we know whether the soil is actually organic.”

    Elman believes the loss of her sight was a gift from God. She said, “It allowed me to pay attention to what I thought was important. Therefore, adapt to a situation, and you'll be all right. Because you can't change it anyway, right?”

    Thirteen-year-old American Jessica Goldstone wants to be a fashion designer when she finishes school. She thinks her designs would be more exciting than clothes bought from stores. But until this month, Jessica has never touched a sewing machine(缝纫机).

    After her first class, Jessica and six other girls aged 9 to 13 said that sewing was fun, cool and challenging.

    These students at Fabrics' Sew Fun class show that the sewing machine is becoming popular again.

    "There have been a lot of teens getting excited about sewing," said a sewing company worker Donna Smith. "Some of them come from the Project Runway TV show," she said. This TV show is an exciting weekly contest to make a great fashion designer. Every week one contestant (参赛者) fails the test and has to leave the contest.

    The number of people who joined sewing class summer camps grew by 10 percent this year. That's good news for companies that make sewing machines and publish sewing magazines. The Singer Sewing Company sold nearly 3 million sewing machines in the United States last year. This is about twice as many as in 1999.

    Sewing machines have been around for more than 150 years, but they have changed a lot since your grandmother was a girl.

    Spencer Carmel started sewing lessons after getting a sewing machine for her 11th birthday. She has sewn a lot by hand, but she wants to make more difficult things. Spencer's class recently made hats.

    Another member of the class, Kelsey Oen, 9 years old, needed time to get used to her machine, but soon she could use it well. By the end of the class, Kelsey was happy and wearing her new hat.
