[简答题] THE HYDROGEN ECONOMY It seems like every day there is a new announcement in the news about automobiles powered by fuel cells. The promises are great, since fuel cells have the potential to very quickly double the efficiency of cars while significantly reducing air pollution. At the same time, there have been news stories for decades about the problems associated With petroleum. Everything from oil spills to ozone(臭氧) alerts to global warming gets blamed on our dependence on fossil(化石) fuels. These two forces are leading the world toward what is broadly known as the hydrogen economy. If the predictions are true, over the next several decades we will all begin to see an amazing shift away from the fossil fuel economy we have today toward a much cleaner hydrogen future. Problems with the fossil fuel economy While fossil fuels have played an important role in getting society to the point it is at today, there are four big problems that fossil

[单项选择]Every living thing has an inner biological clock that controls behavior. The clock works all the time; even when there are no outside signs to mark the passing of time. The biological clock tells plants when to form flowers and when the flowers should open. It tells insects when to leave the protective cocoon and fly away. And it tells animals when to eat, sleep and wake. It controls body temperature, the release of some hormones and even dreams. These natural daily events are circadian rhythms.
Man has known about them for thousands of years. But the first scientific observation of circadian rhythms was not made until 1729. In that year a French astronomer, Jean Jacques d’Ortous de Mairan, noted that one of his plants opened its leaves at the same time every morning, and closed them at the same time every night. The plant did this even when he kept it in a dark place all the time.
Later scientists wondered about circadian rhythms in humans. They learned that man’s biological
A. every creature has an inner biological clock.

Every year, Fortune magazine celebrates women in the top echelons of corporate America by publishing a list Of the 50 Most Powerful Women in Business. Their titles are impressive -- CEO, chairman, president -- and photos portray them as polished and confident. What an inspiration they could be to the young women following them.
（41） But what if those young women don’ t aspire to a comer office A week after the Fortune list appeared on newsstands, a major national study of teenagers revealed a surprising finding- while 97 percent of girls polled expect to work to support themselves or their families, only 9 percent want careers in business. Among boys, the figure is 15 percent. "Girls of this generation are quite ambitious, which is exciting," says Fiona Wilson, a professor’*at Simmons College School of Management and an author of the study, which polled more than 3,000 girls and 1,200 boys in middle school and high school. She finds it encoura
