    Raymond Wang, 17, of Canada was awarded first place for a device that improves air quality on airplanes while cutting down the spreading of diseases at this year’s Intel International Science and Engineering Fair (ISEF).

    According to Intel, Wang's system improves the quality of fresh air in a plane cabin by more than 190 per cent, while cutting diseases by up to 55 times, compared to conventional designs. Intel noted that Wang's invention could be easily and economically fixed into existing airplanes.

    Two other teen researchers earned awards of $50,000 each at the event. One developed a technique to more quickly diagnose diseases caused by HIV. It’s the virus responsible for AIDS. The other invented a device to more quickly shut down undersea oil spills.

    “Intel believes young people are the key to future innovation and that in order to confront the global challenges of tomorrow, we need students from all backgrounds to get involved in science, technology and engineering,” says Wendy Hawkins, executive director of the Intel Foundation. “We hope these winners will inspire other young people to pursue their interest in these fields,” she says, “and apply their curiosity and creativity to the common good.”

    This year's Intel International Science and Engineering Fair featured approximately 1,700 young scientists selected from more than 75 countries and regions. In addition to the top winners, 600 finalists received awards and prizes for their innovative research.

    The Intel International Science and Engineering Fair honours the world’s most promising student scientists, inventors and engineers. Their projects are then evaluated online by nearly 1,000 judges from almost every scientific field.

    The 2015 Intel ISEF is funded jointly by Intel and the Intel Foundation with additional awards and support from dozens of other academic, governmental and scientific organizations. This year, US$4 million was awarded.

    5．I needed to buy a digital camera，one that was simply good at taking good snaps （快照），maybe occasionally for magazines．Being the cautious type，I fancied a reliable brand．So I went on the net，spent 15minutes reading product reviews on good websites，wrote down the names of three top recommendations and headed for my nearest big friendly camera store．There in the cupboard was one of the cameras on my list．And it was on special offer．Oh joy．I pointed at it and asked an assistant，"Can I have one of those？"He looked perturbed （不安）．"Do you want to try it first？"he said．It didn't quite sound like a question．"Do I need to？"I replied．"There's nothing wrong with it？"This made him look a bit insulted and I started to feel bad．"No，no．But you should try it，"he said encouragingly．"Compare it with the others．"
       I looked across at the others：shelves of similar cameras placed along the wall，offering a wide range of slightly different prices and discounts，with each company selling a range of models based around the same basic box．With so many models to choose from，it seemed that I would have to spend hours weighing X against Y，always trying to take Z and possibly H into account at the same time．But when I had finished，I would still have only the same two certainties that I had entered the store with：first，soon after I carried my new camera out of the shop，it would be worth half what I paid for it； and second，my wonderful camera would very quickly be replaced by a new model．
      But something in the human soul whispers that you can beat these traps by making the right choice，the clever choice，the wise choice．In the end，I agreed to try the model I had chosen．The assistant seemed a sincere man．So I let him take out my chosen camera from the cupboard，show how it took excellent pictures of my fellow shoppers…and when he started to introduce the special features，I interrupted to ask whether I needed to buy a carry-case and a memory card as well．
       Why do we think that new options （选择） still offer us anything new？Perhaps it is because they offer an opportunity to avoid facing the fact that our real choices in this culture are far more limited than we would like to imagine．

    57．The shop assistant insisted that the writer shouldB．
    A．try the camera to see if there was anything wrong with it
    B．compare the camera he had chosen with the others
    C．get more information about different companies
    D．trust him and stop asking questions
    58．What does the writer mean by"it would be worth half what I paid for it"（Paragraph 2）？D
    A．He should get a 50% discount．
    B．The price of the camera was unreasonably high．
    C．The quality of the camera was not good．
    D．The camera would soon fall in value．
    59．The writer decided to try the model he had chosen because heC．
    A．knew very little about it
    B．didn't trust the shop assistant
    C．wanted to make sure the one he chose would be the best
    D．had a special interest in taking pictures of his fellow shoppers
    60．It can be inferred from the passage that in the writer's opinion，C
    A．people waste too much money on cameras
    B．cameras have become an important part of our daily life
    C．we don't actually need so many choices when buying a product
    D．famous companies care more about profit than quality．
