[填空题]
Our demand for electricity is climbing so fast that over the
next decade U.S. generating capacity must increase by a third. Fossil fuels
supply nearly three-quarters of this energy. But the smoke-belching stacks of
coal-fired, gas-fired and oil-fired plants are also responsible for about half
of our air pollution.
That, we used to think, is a small price
to pay for progress. But there is an alternative, one that produces no smoke and
can actually create more fuel than it consumes. In many regions it is even
cheaper than coal-fired electricity: nuclear power.
Already
nuclear power is the second largest source of our electricity, and a new family
of "failsafe" nuclear reactors — some now under construction in Japan — may one
day make nuclear power even cheaper and more plentiful.

Would you be happier if you spent more time discussing the
state of the world and the meaning of life--and less time talking about the
weather
It may sound counterintuitive(违反直觉的), but
people who spend more of their day having deep discussions and less time
engaging in small talk seem to be happier, said Matthias Mehl, a psychologist at
the University of Arizona who published a study on the {{U}} (47) {{/U}}.
"We found this so interesting, because it could have gone the
other way--it could have been, ’Don’t worry, be happy’--as long as you surf on
the {{U}} (48) {{/U}} level of life you’re happy, and if you go into the
essential depths you’ll be unhappy," Dr.Mehl said.
But, he
