As far as we know batteries are playing an important role in our life. We couldn't live without batteries. Why so? Batteries provide power for anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri (MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.

" To provide enough power, we need certain methods with high energy density (密度)", said Jae Kwon, assistant professor of electrical and computer engineering at MU." The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries."

Kwo n and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro/ nanoelectromechanreal systems(M/NEMS). Although nuclear batteries can cause concerns, Kwon said, they are safe.

" People bear the word‘ nuclear' and think of something very dangerous," he said," However, nuclear power sources have already been safely powering a variety of devices, such as pace- makers, space satellites and underwater systems."

His new idea is not only in the battery's size, but also in its semiconductor(半导体). Kwon's battery uses a liquid semiconductor rather than a solid semiconductor.

" The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor, Kwo n said," By using a liquid semiconductor, we believe we can minimize that problem."

Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwo n is working to build and test the battery. In the future, they hope to increase the battery's power, shrink its size and try with various other materials. Kwo n said that battery could be thinner than the thickness of human hair.

(1)、According to paragraph 1 and 2, we can learn that ____.
A、batteries can only power small sensors B、the larger batteries are, the more power they can provide C、Jae Kwo n is working hard to improve chemical batteries D、certain methods with high energy density can provide power abundantly
(2)、Jae Kwo n gave examples in Paragraph 4____.
A、to introduce various energy sources B、to describe a nuclear- powered system C、to introduce nuclear batteries can be safely used D、to show chemical batteries are widely applied
(3)、Liquid semiconductor is used to ____.
A、get rid of the radioactive waste B、decline the damage to lattice structure C、test the power of nuclear batteries D、decrease the size of nuclear batteries
(4)、According to Jae Kwon, his nuclear battery ____.
A、could be extremely thin B、will soon replace the present ones has. C、uses a solid semiconductor D、passed the final test
举一反三

    Recently some articles claim the word “selfie” as one of the most annoying words. But I'd like to offer that maybe it isn't not so bad.

    The “selfie” is used to describe the self taken photo, often from a smart phone. Women and men alike adorn their Instagram, Facebook and Twitter accounts with these pictures, sometimes with puckered lips or large smiles. In fact, the selfie has become so widely known that over 31 million photos on Instagram are captioned with the selfie.

    Let's think about it. Someone takes about 10 seizes each time they do, and they only end up posting one or two of those. They pick the one that they feel makes them look the best. Isn't that beautiful? In that one picture, someone has even him or herself confidence.

    Self-image is important. In society today, we are so often consumed with what society tells us is perfect. But maybe, with that one selfie, we feel like we fit that bill. We feel handsome, beautiful, confident, smart, happy and content. For that moment, everything bad or terrible that has ever happened to us is erased, because that smile or that pucker is what gives us the determination to love ourselves.

    I saw a spoken word poem recently and the young man said: If I ask you what you love the answers will most likely roll off your tongue. You love to read. You love to write. You love birds, music, tattoos… Your mom, your brother, your sister, your daughter, your best friend, your dog. How long do you think you could go on and on before you said “I love myself”?

    That statement hit me like a ton of bricks. I've struggled with confidence all of my life. I still do. And in no way am I saying that taking a selfie is a gateway to that confidence. However, the selfie does deserve some credit for allowing individuals to express themselves. Pamela Rutledge agrees, stating, “There are many more photographs available now of real people than models.”

    Far out in the lake was a large wooden platform(平台) on which stood an improbably high diving board- a kind of wooden Eiffel Tower. It was, I'm sure, the county's tallest wooden structure (结构) and no one had ever been known to jump from it. So it was quite a shock when our teacher, Mr. Milton, announced that he would dive off the high board that very afternoon.

    Word of his questionable plan was already spreading through town as Mr. Milton swam out to the platform. He was just a tiny, stick figure when he got there but even from such a distance the high board seemed almost to touch the clouds. Once at the top, he paced the enormously long board , then look some deep breaths and finally stood at the edge. He was going to do it.

    Several hundred people had gathered at the shore to watch. Mr. Milton stood for quite along time ;then he raised his arms, took one bounce(弹跳) and launched himself into ;perfect dive. He fell with perfect style for what seemed minutes. The crowd fell silent. But about three quarters of the way down he seemed to have second thoughts and began suddenly to panic(惊慌),waving his arms and legs like someone having a bad dream. When he was perhaps thirty feet above the water, he gave up on waving and spread his arms and legs wide, obviously hoping that it would somehow slow his fall. It didn't. He hit the water at over six hundred miles an hour, making birds fly out of their trees three miles away. I don't think he entered the water at all. He just bounced off it, about fifteen feet back into the air. After that, he lay still on the surface , like an autumn leaf.

    He was brought to shore by two passing fishermen in a rowboat and placed on an old blanket where he spent the rest of the afternoon. Occasionally he accepted a little water, but otherwise was too shocked to speak.

    It was the best day of my life.

    Being seen in a fancy sports car or enjoying a beach holiday in a five-star hotel were once signs of having “made it”.

    But a new study suggested that having people think of you as constantly busy and overworked is now a far better way to show social status.

    According to Harvard University in the US, people are increasingly leaning toward the phenomenon of “humblebragging (谦虚自夸)”. This is when people make a seemingly modest statement that actually draws attention to something they want to brag (吹嘘) about.

    Phrases such as “I have no life” and “I desperately need a holiday” are now used to imply social standing, while ordering food and shopping online is the perfect way to prove to neighbors that you are simply too busy and important to go to the supermarket.

    “Movies, magazines, and popular TV shows often highlight (强调) the abundance (富足) of money and leisure time among the wealthy,” said Neeru Paharia, an assistant professor at Harvard University.

    “In recent years, featuring wealthy people relaxing by the pool or on a yacht (游艇), playing tennis or skiing and hunting are being replaced with advertisements featuring busy individuals who work long hours and have very limited leisure time,” he said. “Displaying (how busy you are at work) and a lack of leisure time operates as a visible signal of status in the eyes of others.”

    The researchers pointed out that the Wall Street Journal's 2016 advert campaign featured celebrities (名人) complaining about their busy lives, with the slogan (标语). “People who don't have time, make time to read the Wall Street Journal.”

    The report, which was published in the Journal of Consumer Research, also found that brands that marketed themselves as timesaving were becoming increasingly high-status, because of the people who used them.

    According to the authors, this trend of humblebragging is due to people's shit of focus-they now value “the preciousness und scarcity (稀缺) of individuals" more than “the preciousness and scarcity of goods”.

    “Busy individuals possess desirable characteristics, leading them to be viewed as scarce and in demand,” the authors concluded.

    Last week, two companies, Kitty Hawk and Uber, announced their plans to bring flying cars to reality very soon.

    Imagine never having to worry about traffic, stop lights, or road construction. A flying car would get to a place much faster than one travelling by road. On the other hand, imagine having to avoid drones (无人驾驶飞机) and other flying cars. Also, what if your battery dies when you are in the air? And, how will you know where to land?

    Kitty Hawk is a start-up tech company supported by Google co-founder, Larry Page. According to the Kitty Hawk website, its car will be able to travel at speeds up to 40 kilometers an hour in the air. It says under US aviation law such a machine “does not require registration or a pilot's license and may be flown in uncongested (不拥挤的) areas for recreational purposes.” As of now, the car can only be flown over fresh water.

    Kitty Hawk is making a list of people interested in buying the flying car. They must pay a deposit of US$100. Those who get their names on the list early will receive US$2, 000 off the final cost of the car. However, Kitty Hawk has not yet announced the price. Kitty Hawk expects its first flying cars will go on sale by the end of this year.

    At a conference last week, Uber announced plans for flying taxis to begin carrying passengers. Unlike the Kitty Hawk company, Uber does not plan to build its flying cars. Instead, it will use the resources of partner companies.

    Like the Kitty Hawk car, Uber flying taxis will use electric power. Uber says its flying taxis could travel up to 241 kilometers an hour. The company said that could reduce the travel time between San Francisco and San Jose, California from two hours on the road to 15 minutes in the air.

    Riders could use the Uber app to book a flying taxi to take them to their destinations. The company has not yet said how costly air taxi travel would be compared to road taxi travel.

Grandma celebrated her fifty-third birthday just weeks before grandpa died of cancer in 1965. Although his passing was very difficult for her, I think their shared struggle to make his life longer taught grandma that good health was not to be taken for granted, and she made up her mind to live her rest of her own life as fully and as long as she could. One day, when she announced to attend lessons at the Fred Astaire Dance Studio in Portland, Oregon, where she lived, we rolled our eyes in embarrassment and helplessly wished she would just stay home and bake cookies as normal grandmothers did. Many years filled with countless dance lessons passed before we learned to appreciate the wonder of having a dancing grandma.

I suppose grandma's primary motivation for wanting to learn to dance was social. She had been a shy girl, always very tall and heavy, and had married into grandpa's quiet lifestyle before developing any elegance or confidence in her personal appearance. Dancing, on the other hand, filled her life with flash lights, wonderful parties, beautiful dresses, handsome young dance instructors, and the challenge of learning. Although the weekly dance lessons did not change her ample, two-hundred-pound figure, grandma surprised everyone with energetic performances on the dance floor, which soon gave her as much elegance and confidence as any Miss American competitor.

Having taken weekly dance lessons for years, my grandma learned various dances easily and was soon participating in dancing matches all over the Northwest. When I was fourteen, grandma proudly invited me to watch her compete in one of these matches to be held in the grand ballroom of the Red Lion Inn. My attitude was still unenthusiastic at that point, but to make her happy, my mother and I attended the match. As if to prove me wrong, grandma made a wonderful showing in every event she entered. I thought she was truly the queen of the ball during the dance, and my thoughts were shared by the judges a short time later when she was awarded a gold cup for her outstanding performance.
