    Ten minutes of gentle exercise can immediately change how certain parts of the brain communicate and coordinate (协调) with one another and improve memory function, according to an encouraging new study.

    The scientists invited 36 people of different ages to the lab and had them sit quietly on a fixed bicycle for 10 minutes or, on a separate visit, pedal the bicycle at a pace so gentle that it barely raised their heart rates. It also was short, lasting for only 10 minutes. Immediately after each session of the sitting or slow pedaling, the people completed a computerized memory test during which they would see a brief picture of, for instance, a tree, followed by a variety of other images and then a new image of either the same tree or a similar one. The people would press buttons to show whether they thought each image was new or the same as an earlier shot. The test is difficult, since many of the images closely resemble one another. It requires rapid, skillful scanning recent memories to decide whether a picture is new or known. Next, the scientists had each people repeat this process--riding or sitting on the bike for 10 minutes and then completing memory testing--but the testing now took place inside an M. R. I. machine(磁共振成像仪)that scanned the people's brains while they responded to the images.

    Then the researchers compared results. The effects of the exercise were clear. The people were better at remembering images after they had ridden the bike, especially when the images most closely resembled one another. In other words, the harder their memories had to do their best, the better they performed after the exercise. The M. R. I. scans showed that memory parts of each people's brain lit up at the same time with parts of the brain associated with learning, indicating that these physically separate parts of the brain were better connected now than when the people had not first exercised.

(1)、How did the researchers conduct the study?
A、By filling up questionnaires. B、By interviewing many people. C、By comparing experiment data. D、By referring to historical reports.
(2)、Who might benefit most from the study result?
A、The marketers promoting fixed bicycles. B、The young people crazy about body building. C、The white collars doing long-term mental work. D、The blue-collars doing heavy physical labor work.
(3)、Which of the following statements agrees with the study result?
A、The light exercise is only good for young people. B、The more the exercise is, the better the brain works. C、The exercise can coordinate different parts of the body. D、The exercise has more positive effect when the brain works harder.
(4)、What can be the best title for the text?
A、Even ten minutes' exercise may be good for the brain B、There is no need for humans doing exercise every day C、Only ten minutes' light exercise benefits the young most D、Exercise can change people's brains and minds in a long time

    Recently actor Adrien Grenier has launched(发动)a campaign to reduce the amount of single-use plastic usage in order to protect and save marine (海洋的)wildlife and the environment. Plastic drinking straws are among many single-use plastic products contributing to the great loss of marine life, but they're a great place to start because they're something that are used by millions of Americans who are unaware that they're so damaging.

    Americans use more than 500 million straws daily, which is enough to fill 127 school buses each day and they can't be recycled. That means plastic straws might end up in oceans, where fish and other marine wildlife mistake the small bits for food and swallow them. After seeing a photo of a beached whale with a belly full of plastic, Grenier felt the inspiration to launch the Lonely Whale Foundation, hoping to inspire and educate others on the challenges faced by marine wildlife.

    Along with stopping the use of straws, Grenier hopes to educate consumer on the dangers of other single-use plastic items such as grocery bags and water bottles. While many Americans use these plastic products in their daily life, there are many alternatives that can help protect the environment such as straws made from stainless steel, glass, and even bamboo instead of plastic.

    In addition to quitting your straw habit, you can further help the environment by taking the I Choose to Reuse commitment, and stop your use of single-use coffee cups, checkout bags and bottled water. Instead, take advantage of any number of alternative reusable products.

    Need another reason to stop drinking from straws? Grenier also says using straws can cause wrinkles!

    “Have a nice day!” may be a pleasant gesture or a meaningless expression. When my friend Maxie says “Have a nice day!” with a smile, I know she sincerely cares about what happens to me. I feel loved and secure since another person cares about me and wishes me well.

    “Have a nice day. Next!” This version(版本) of the expression is spoken by a salesgirl at the supermarket who is rushing me and my groceries out the door. The words come out in the same tone with a fixed procedure. They are spoken at me, not to me. Obviously, the concern for my day and everyone else's is the management's attempt to increase business.

    The expression is one of those behaviors that help people get along with each other. Sometimes it indicates the end of a meeting. As soon as you hear it, you know the meeting is at an end. Sometimes the expression saves us when we don't know what to say. “Oh, you just had a tooth out? I'm terribly sorry, but have a nice day.”

    The expression can be pleasant. If a stranger says “Have a nice day” to you, you may find it heart-warming because someone you don't know has tried to be nice to you.

    Although the use of the expression is an insincere, meaningless social custom at times, there is nothing wrong with the sentence except that others who speak it without thinking may not really care about my day. But in a strange and comfortable way, it's nice to know they care enough to pretend they care when they really don't care all that much. While the expression may not often be sincere, it is always spoken. The point is that people say it all the time when they like.

    As Simon Kindleysides, 34, took his first step in the London Marathon in April, he felt as if magic was in the air.

    "As we were walking toward the first mile, we actually started joining all the runners," he said. "Everyone was on the streets, cheering, and that was a magical moment." As time went on, the crowds and other racers spread around. Kindleysides and his team of eight supporters continued walking.

    Kindleysides, who is paralyzed(瘫痪的)from the waist down and typically uses a wheelchair, was equipped with an exoskeleton(体外骨骼)to help him walk. His supporters walked with him to change the batteries in his exoskeleton so he could keep moving.

    In 2013, Kindleysides was diagnosed with a brain tumor (肿瘤) that was growing in a way that pressed on certain nerves, leading to him losing feeling in his legs. He was told he would never walk again. Before his paralysis, the London­based singer and dancer had "always wanted to run a marathon," he said, but he never made the plan to do so­­until this year.

    During the London Marathon, the last two miles were the hardest. "At that point, I was exhausted. It was freezing cold, and I was hurting emotionally," Kindleysides said. But he kept going. "I didn't want to let people down. I had a team of eight, and I was raising money for The Brain Tumour Charity," he said. "I didn't want to let them down, myself down, and I thought if I would get this far, I would have to continue."So he continued and made history as the first paralyzed man to complete the London Marathon on foot.

    Then, recovering at home, he shared his accomplishment with his three children. "They used to say I'm the only dad in their whole school who's in a wheelchair, and now they say I'm their dad, the only one who has walked a marathon," he said.

    Kindleysides is training to complete three more marathons next year, including the London Marathon again.

    I've always felt a need to be prepared for whatever situation I've found myself in.

    My mother once took me to a store when I was seven years old. She and I got to the checkout counter, and she realized she had forgotten a couple of things on her shopping list. She left me with the cart and ran off to get what she needed.

    "I'll be right back." she said.

    She was gone just a few minutes, but at that time, I had loaded all the things on the belt and everything was rung up. I was left staring at the cashier, who was staring at me. "Do you have money for me, son?" she said. "I'll need to be paid."

    I didn't realize she was just trying to please herself. So I stood there, ashamed and embarrassed.

    By the time my mom returned, I was angry. "You left me here with no money! This lady asked me for the money, and I had nothing to give her."

    Now that I'm an adult, you'll never catch me with less than $200 in my wallet. I want to be prepared in case I need it.

    I've always admired people who are over-prepared. In college, I had a classmate named Norman. One day he was giving a speech on an overhead projector(投影仪) and in the middle of his talk, the light bulb(灯泡)on the projector blew out. We would have to wait ten minutes until someone found a new projector.

    "It's Okay." he said. "There's nothing to worry about."

    We watched him walk over to his bag and pull something out. He had brought along a spare(备用) bulb for the overhead projector. Who could even think of that?

    I often told my students, "When you go into the wilderness, the only thing you can depend on is what you take with you." And essentially, the wilderness is anywhere but your home or office. So take money. Pack a light bulb. Be prepared.

    Two heads are better than one. After all, when trying to make decisions, it's good to have a second opinion. But what about a third, fourth — even twelfth? What group size is best for making decisions quickly? For ants, four to six heads surpass one and also outperform 12 or 24. That's what Sylvia Zamescu now reports.

    The 18-year-old senior at Catalina Foothills High School in Tucson, Arizona isn't generally into ants. She's interested in decision-making, especially by people. Last summer, Sylvia read that social insects such as ants and bees can be used to model decision-making. Ants, for example, forage for food. When an ant finds it, it takes a bite and heads back to the nest. On the way; the ant leaves a scented trail for other ants to pick up. Back at the nest, the ant vomits up its meal into the mouth of other ants. Those nest-mates then decide with the first ant whether the food is good enough to deserve a trip back for more. If it is, they follow the first ant's scented trail to lunch.

    When there are too few ants, it could take a long time for one ant to spread the word. If there are too many, it's hard to "tell" each about the find. What's the right number for foraging success? Sylvia decided to find out. She contacted professors at the University of Arizona in Tucson to look for someone who would let her study decision-making by ants in their lab. Professor Wulfila Gronenberg answered her email.

    Working with one of Wulfila's graduate students Sylvia set up an experiment. She tested the behavior of one, two, four, six, twelve and twenty-four ants. Each group was placed in a large box al taped "starting line". At the other end of the box were two bricks of sweetened gelatin (动物胶) one contained only 3 per cent sugar, and the other 30 per cent. Sylvia timed how long it took each group of ants to find the food. She also measured how much time they spent around each sweet treat.

    When there were just one or two ants, the discovery was slow. The same was true when she set twelve or twenty-four ants loose. But four to six ants? Perfect! These medium-size groups found the food forest. They also figured out quickly that the sweeter food was better.

    Similar work has been done on bighorn sheep, fish and fruit flies. "It may not be four to six animals, but it's the same principle," Sylvia says. A medium-size group "is optimal". So when faced with a new decision, two heads are better than one. But too many heads are too much. Like the ants, a good decision may just require a happy medium.
