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．
In terms of nanotechnology, Kim was the first______．
选项 A、to use it in washing machines
B、to come up with the idea
C、to introduce it to Korea
D、to apply it to socks
答案A
解析 细节题。文章第二段提到“when he got back to Seoul, Kim applied the principle to washing machines.”，因此应选择[B] 。
