阅读理解

    Quicker and faster 3-D printers have allowed not just amazing objects to be created, but have started to affect how doctors treat patients.

    We've put together a list of some of the most amazingmedical break throughs made possible with 3-D printing.

Life-Saving Airway

    In 2013, doctors created a new airway for kaiba Gionfriddo, aboy born with an airway that kept collapsing (萎陷). To save his life doctors printed tiny tubes to join together in different shapes and sizes until one finally worked for Kaiba. It was placed in Kaiba's bronchus (支气管) so that it no longer collapsed. Even more remarkably, once the plant was placed it couldstay there. It's designed to eventually be absorbed into the body.

New “Bionic” Hands

    One of the most remarkable ways 3-D printing is now being used is as a way to create prosthetics (假肢). A boy born without an arm named Alex was able to get a new“bionic”hand thanks to it. Last year a college student spent 8 weeks coming up with a special prosthetic design that only cost a few hundred dollars in materials. He said he wanted to create a prosthetic far cheaper than other choices that can run tens of thousands of dollars.

A practice Heart

    In Seattle, doctors have been able to use 3-D printing technology to“practice”risky operations so that they will face fewer surprises in the operating room. Kami Sutton was born with her heart“in the wrong place”. For a recent operation her doctor was able to take many scans of Sutton's heart and print out a model. “Kami's heart is truly one-of-a-kind,”Dr. Stephan Seslar, a heart disease specialist said. “Operating on her without understanding the structure of her heart better could be very dangerous.”

A New Skull

    A U.K. man was able to have part of his skull rebuilt thanks toa 3-D printer. Stephen Power broke his cheek bones in a crash. To help Powerh is doctors instead created 3-D bones all carefully printed in the shape of his face. “This is really the first time we've taken it to this stage, where everything has been planned and modeled in advance — and worked sweetly,”said Adrian Sugar, a doctor.

(1)、What is special about the 3-D printed airway?

A、It uses high-tech materials. B、It varies in shapes and sizes. C、It can be absorbed by the body. D、It can prevent any disease in the airway.
(2)、What is the advantage of the new“bionic”hand?

A、Its price. B、Its effects. C、Its materials. D、Its shape design.
(3)、How can 3-D printing technology help doctors in the operating room?

A、It helps them get better scans. B、It guarantees the success of operations. C、It enables them to practice and learn more. D、It helps them to deal with patents, anxiety.
(4)、What does Adrian Sugar think of the new skull printed by 3-D technology?

A、He has doubts about it. B、He thinks highly of it. C、It needs to be better planned. D、It functions well but needs improving.

      Batteries can power 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."
      Kwon 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 / nanoelectromechanical systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.
      "People hear 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 of the solid semiconductor," Kwon 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, Kwon 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. Kwon said that battery could be thinner than the thickness of human hair.

    The Loss of Innocence

    Innocence is such a precious gift. It's explained as freedom from guilt or wrong doing. Just imagine never having to worry about anything and having a guilt free mind. Some people wish to save this kind of innocence from being lost from childhood to adulthood.

    What would the world be like if innocence were never lost? One way it would benefit humanity is the lack of hatred (仇恨)among the world. During youth, there may be an occasional argument, even a little physical fight, but nothing like firing a handgun at a fellow human being. And children are blind towards the racial differences of others. A kid will hang out with any other kid. It is the lack of innocence and the ignorance we learn from adults that influence children otherwise. Another benefit is the constant desire for fun and adventure. With very little if any time at all for fun,the adventurous mind is lost in time with the responsibilities placed upon adults. If innocence were kept alive, these ambitions would never depart from our lives.

    However, other people actually hate the idea of innocence lasting forever. They feel that the lack of organization and mental power of those with innocence would cause extremely destructive consequences to society in general. A large number of individuals would never have the urge to learn, work, and act upon the necessary needs for humanity to survive. Without a proper education which is usually provided by those who no longer live in a world of innocence, people would not have the desire to succeed, get a good job in life, or provide income for their families, which would hurt the lives of children.

    The lack of a good education and career would also harm the economy. As long as innocence is kept alive, no one would be terribly angered at the lack of effort people put out in the workplace, resulting in a strong decline in production and quality of needed goods.

    Maybe it is wrong in wanting to save innocence. It sure is a nice thought, though. Perhaps innocence was meant to be lost. It was God's will to make things the way they are, and there is a good purpose for everything. All that remains to be said about innocence is to enjoy it while it lasts.

Beijing Imperial Court Food

    Imperial Court Food(宫廷菜) is a style of food with origins in the Imperial Palace and it is well-known for the original features of the raw materials and carefully selected ingredients(原料). In addition, the dishes are decorated with different colored vegetables and fruits in various shapes. Each dish has a special name, such as Yu Feng Huan Chao. And some of them even have short stories. Today, Imperial Court Food has become an important school of Chinese cooking with several places offering this special taste. While expensive, it is worth trying.

    Restaurants of Imperial Court Food

    Fangshan Restaurant

    Fangshan Restaurant is the most famous one offering the first-class Imperial Court Food. The restaurant is made up of three parts and it can hold 500 people eating at the same time. It is decorated in imperial style with the design of dragon and phoenix. Here is the best place to experience the life of the Chinese emperors in former days. Now, it serves nearly 800 kinds of Imperial Court Dishes. Among them, Man-Han Banquet is the most famous.

    Li Jia Cai Restaurant

    The dinner here is served by set menu starting at ¥298/person. That is to say, a guest cannot order a dish but a set of dishes. There are no chemicals in the dishes and all tastes are natural. This restaurant has welcomed many famous people including Bill Gates, the former premier of Britain, John Major, and Chinese superstar Jackie Chan.

    Yushan Restaurant

    The layout of the restaurant follows the imperial palace. When eating in the restaurant, diners are served by waitresses in traditional imperial clothes.

    Da Zhai Men

    The dishes and snacks cooked in this restaurant are worthy to have a try. And, the traditional performances at night is one of the restaurant's attractions.

    Royal Palace

    Both of the food and service of this restaurant are so good. You can also enjoy some wonderful performances in this large courtyard.

Choose the one that fits best according to the information given in the passage you have just read.

    Few facts about modern life seem more undeniable than how busy everyone seems to be. Across the industrialized world, large numbers of survey respondents tell researchers they're overburdened with work, at the expense of time with family and friends.

    But the total time people are working, whether paid or otherwise, has not increased in Europe or North America in recent decades. What's more, the date also show that the people who say they're the busiest generally aren't.

    Part of the answer is simple economics. As economies grow, and the incomes of the better-off have risen over time, time has literally become more valuable: Any given hour is worth more, so we experience more pressure to squeeze in more work.

But it's also a result of the kind of work in which many of us are engaged. In the past, farming work was subject to weather limits, white at present people live in an "unlimited world," and there are always more incoming emails, more meetings, more things to read, and digital mobile technology means you have a few more to-do list items.

    With time pressure weighing us down, it's hardly surprising that we live with one eye on the clock. But psychological research demonstrates that this time-awareness actually leads to worse performance. So the ironic consequence of the "busy feeling" is that we could handle to-do list less well than if we weren't so rushed.

    Arguable worst of all, the feeling of rush spreads to affect our leisure time, so that even when life finally does permit an hour or two for recovery, we end up feeling that leisure time should be spent "productively," too.

    If there's a solution to the busyness epidemic(流行病), other than the universal 21-hour workweek, it may lie in clearly realizing just how reasonable our attitudes have become. Historically, the ultimate symbol of wealth, achievement and social superiority was the freedom not to work. Now, it's busyness that has become the indicator of high status. "The best-off in our society are often very busy, and have to be," says Gershunny. "You ask me, am I busy, and I tell you: "Yes, of course I'm busy because I'm an important person!"

    Too often, we measure our worth not by the results we achieve, but by how much of our time we spend. We live crazy lives, at least in part, because it makes us feel good about ourselves.
