ARunning a marathon is not easy. It takes hard work, practice, and patience. After all, to run a marathon, you have to run 26.2 miles by foot! Think about it this way: 26.2 miles is the same as running the length of a football field more than 460 times. It takes most people four or five hours to finish.By the age of 30, Lea Tambellini had run more than five marathons and had no plans to stop. She had always been an athlete. When she was in high school, she swam on her school’s swim team and ran to stay healthy and active. Her mom and dad ran marathons, and when she was 22, they helped her train for her first marathon.Lea's first marathon took place in Cincinnati, Ohio, and was called “The Flying Pig.”“I was very nervous,” she said, “but I had my mom there, so that helped.” Running the race was hard, but the hardest part was when she ran past a cookie factory and smelled cookies at mile 18. “1 just wanted to be done,” she said. “I was spent, my mom kept me going. It was already her 15th Marathon.”Today, thousands of people run marathons every year. Runners train for months to get ready. To prepare for one of the marathons, Lea ran four to five times every week. On weekdays. she completed shorter runs, five or six miles at most. But on the weekends she ran long distances—13 miles, 15 miles, and 20 miles!“I don' t mind training because I get excited about working toward something. And I love running with a group of friends and working toward the goal together. But it does take a lot of Time.”Running a marathon is a great achievement. “it's a great feeling of accomplishment and nothing feels as wonderful as reaching my goal when I cross the finish line,” Lea explained.“I can’t wait for the next one!”21. What contributed to Lea becoming a marathon runner?A. Her great patience and life ambition to be a successful athlete.B. Her strong interest in swimming and long-distance running.C. Her athletic experience and her parents guidance.D. Her love for running with friends and achieving a goal together.22. What does Lea mean by saying “I was spent” in paragraph 3?A. I was extremely exhausted.B. I felt like quitting my sporting career.C. I was feeling increasingly nervous.D. I was overcome by hunger.23. How did Lea's feeling of running a marathon change over the years?A. From curiosity to enthusiasm.B. From nervousness to excitement.C. From thrill to boredom.D. From delight to disappointment.BResearchers have discovered an inner ear deficiency (缺陷) in children with Autism Spectrum Disorder (ASD, 自闭症) that may greatly influence their ability to recognize speech. The finding could be used as a way to identify children at risk for the disorder at an early age. “This study is meant to identify a simple and safe method to screen young children for hearing deficiencies that are associated with Autism,”said Anne Luebke, Ph. D, a professor in the University of Rochester. “This technique may provide doctors a new window into the disorder and enable us to take earlier action and help achieve desirable outcomes.”ASD is a nerve developmental disorder characterized by damage in social-communication skills and restricted and repetitive behaviors. While many signs of ASD are present before age two, the majority of children with ASD are not diagnosed until after age four, which means that corrective treatments are started later, delaying their potential impact.One of the challenges to earlier detection of ASD is to find ways to identify children at risk for the disorder sooner and in children with speech delays. Some of the earliest and continuous signs of ASD involve auditory (听觉) communication, however, most tests rely on speech, and are often ineffective in small children who have communication delays.In the new study, researchers used a technique that measures what are called otoacoustic emissions(耳声发射). The test is similar to the screening that many newborns must undergo before leaving the hospital to check for hearing problems. Using microphone earplugs, the researchers were able to measure hearing deficiencies by listening for signs that the ear is having trouble processing sounds. Specifically, the microphone can detect minute sound emission made by inner ear outer hair cells in response to even clicking sounds. If these cells are not functioning properly, the device fails to detect an emission, indicating that inner ear function is damaged. The researchers tested the hearing of children between 6 and 17, roughly half of those diagnosed with ASD. They found that the children with ASD had hearing difficulty in a specific frequency that is important for processing speech.

Load bags with canned foods for the hungry. Make donations to those who need it. This time of year, it seems, we focus more on doing good and being good. Certainly, that's not a bad thing.But, is all that kindness selfish? Researchers at the University of California, Berkeley say that kindness, and related qualities like sympathy and compassion are actually a form of self- preservation. Those who give more, get more. The most generous among us have greater influence and are more popular. Whereas, the unkind and unhelpful are more likely to be cast adrift from us. After all, it stands to reason, that if I'm paddling your lifeboat, you’ll keep me afloat a little longer.So, is kindness motivated by our real concern for others or are we do-gooders because it makes us look good and shores up our position in the ecosystem? Probably both. Most of us really enjoy helping others. It makes us feel good, connected, happy and that makes for a healthier more satisfying life. But, it doesn’t hurt that we also receive other rewards —status, cooperation, Influence —that will help us survive and become successful.Despite all the benefits, I tend most often toward kindness only when it's convenient. That doesn't mean I have bad manners. I say my pleases and thank-yous. I hold the door open for passengers. But, I could be kinder, more often. Sometimes I'm stopped from doing good by just how to do it. Sometimes, I'm just not thinking enough about others to recognize the need. Sometimes, I’m plain, old selfish.I'm working to be more aware of those around me. To slow down and move with patience and purpose on the freeway. To be more kind. My acts of kindness aren’t complex or flashy —I'm not the type. They aren't expensive —I’m too cheap. But those things aren’t required. You don’t have to feel guilty that your kind gesture wasn't as big as say, Oprah building a school in Africa. Kindness can be a small, simple act and still make an extremely large impact. Notice a need and then consciously offer a bit of yourself.27. What do researchers at the University of California. Berkeley say about kindness?A.
