问题     To find Kim Hyung Gyoon’s office in Samsung’s R&D complex，iust follow the baskets of dirty clothes．No, Kim is not running the company laundry．As chief of Samsung’s Washing & Cleaning Technology Group(WCTG)，he’s the man behind a new washing machine that deposits tiny silver particles(small pieces of things)-about 1/10,000 the thickness of a human hair—onto clothes to make them germ-and-odor- free without the need for hot water．The device represents the first mass-produced application of this type of nanotechnology—the science of very small structures—to home appliances．"In summer of 2002, I asked everyone in the office to take off their socks,"says Kim．"I took one sock from each person and placed it in a regular washing machine; the others were washed in a machine with the Ag + Nano System．The next day, I asked everyone to check the odor of their socks after a day’s wear．One began to produce a strong unpleasant smell, and the other was odorless．"
    Kim says he came up with the idea five years ago while on a business trip to Japan,  where he learned of a brand of socks that retained their freshness even after many days of unwashed wear and tear．Tiny sticks of silver with germ-killing chemicals were woven into fabric．When he got back to Seoul, Kim applied the principle to washing machines．
    According to the Korea Testing & Research Institute for the Chemical Industry, Samsung’s device killed 99.9% of germs．Kim says garments stay germ-free for up to a month after being laundered．The Ag + Nano device went on sale in March 2003 and costs around $1,150; the revolutionary technology is also being used in Samsung’s refrigerators and air conditioners．
    No wonder: consumers seem to like a little silver in their spin cycles．Since Samsung’s nano-armed products were first launched, they have brought in an estimated $779 million in revenue．Overall, nanotech has been one of science’s fastest- growing fields in recent years, with potential applications in fields as diverse as energy production and toothpaste manufacture．The nanotech market is projected to be worth $1 trillion by 2015．
This text centers on______．
选项 A、the success of an enterprise
B、the application of a technology
C、the market share of Samsung’ s WCTG
D、the mass-production of a home appliance
答案B
解析 主旨题。文章都是围绕纳米科技展开的，主要以三星公司的Kim先生 研发的新式洗衣机为例，因此可以推断出，本文是一篇关于科技应用于生 活的文章，应选择[B]。
