{{B}}Technology Transfer in
Germany{{/B}} When it comes to translating basic research into
industrial success, few nations can match Germany. Since the 1940s, the nation's
vast industrial base has been fed with a constant stream of new
ideas and expertise from science. And though German prosperity (繁荣) has faltered
(衰退) over the past decade because of the huge cost of unifying east and west as
well as the global economic decline, it still has an enviable (令人羡慕的) record for
turning ideas into profit. Much of the reason for that success
is the Fraunhofer Society, a network of research institutes that exists solely
to solve industrial problems and create sought-after technologies. .But today
the Fraunhofer institutes have competition. Universities are taking an ever
larger role in technology transfer, and technology parks are springing up all
over. These efforts are being complemented by the federal programs for pumping
money into start-up companies. Such a strategy may sound like a
recipe for economic success, but it is not without its critics. These people
worry that favoring applied research will mean neglecting basic science,
eventually starving industry of flesh ideas. If every scientist starts thinking
like an entrepreneur (企业家), the argument goes, then the traditional principles
of university research being curiosity driven, free and widely available will
suffer. Others claim that many of the programs to promote technology transfer
are a waste of money because half the small businesses that are promoted are
bound to go bankrupt within a few years. While this debate
continues, new ideas flow at a steady rate from Germany's research networks,
which bear famous names such as Helmholtz, Max Planck and Leibniz. Yet it is the
fourth network, the Fraunhofer Society, that plays the greatest role in
technology transfer. Founded in 1949, the Fraunhofer Society is
now Europe's largest organization for applied technology, and has 59 institutes
employing 12,000 people. It continues to grow. Last year it swallowed up the
Heinrich Hertz Institute for Communication Technology in Bedim Today, there are
even Fraunhofers in the US and Asia.

单选题Making Light of Sleep
All we have a clock located inside our brains. Similar to your bedside alarm clock, your internal clock
1
on a 24-hour cycle. This cycle,
2
a circadian (昼夜节奏的，生理节奏的) rhythm, helps control when you wake, when you eat and when you sleep.
Somewhere around puberty (青春期),
3
happens in the timing of the biological dock. The clock pushes forward, so adolescents (青少年) and teenagers are unable to fall asleep as early as they
4
to. When your mother tells you it"s time
5
bed, your body may be pushing you to stay up for several hours more. And the light coming from your computer screen or TV could be pushing you to
6
even later.
This shift is
7
for teenagers. But staying up very late and sleeping late can get your body"s clock out of sync (同步) with the cycle of light and dark. It can also make it hard to get out of bed in the
8
and may bring other problems, too. Teenagers are put in a kind of gray cloud
9
they don"t get enough sleep, says Mary Carskadon, a sleep researcher at Brown University in Providence, RI. It
10
their mood and their ability to think and learn.
But just like your alarm clock, your internal clock can be reset. In fact, it
11
resets itself every day. How? By using the light it gets through your
12
.
Scientists have known for a long time that the light of day and the dark of night
13
important roles in setting our internal clocks. For years, researchers thought that the signals that synchronize the body"s
14
were handled through the same pathways that we use to see.
15
recent discoveries show that the human eye has two separate light-sensing systems. One system allows us to see. The second system tells our body whether it"s day or night.
