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．
单选题
Which of the following best describes the nature of Kim Hyung Gyoon's work?
【正确答案】
A
【答案解析】[解析] 推理题。文章第一段提到Kim把纳米应用于洗衣机，制造出新式洗衣机，第二段提到“When he got back to Seoul, Kim applied the principle to washing machines”可知，Kim先生是做研发的，凶此应选择[A] Product development(产品研发)。
单选题
One advantage of nano-armed washing machines is that______．
单选题
In terms of nanotechnology, Kim was the first______．
【正确答案】
A
