The author is most probably a . A. teacher B. psychologist C. philosopher D. doctor C Imagine putting some bacteria in the freezer and taking them out millions of years later to find that they are still alive. That would be similar to what happened recently, when scientists brought eight-million-year-old bacteria back to life - simply by thawing them out. The ancient bacteria were found frozen in the world's oldest known tracts of ice, the glaciersof Antarctica. Professor Bidle and his colleagues found and revivedtwo samples of bacteria from the glacial ice. The first was a hundred thousand years old, and the second was around eight million years old. The eight-million-year-old bacteria were alive. But their genes were seriously damaged from long exposure to cosmicradiation, which is higher at the earth's poles. Most of the bacteria in the samples probably blew over from African deserts, said Paul Falkowski, a scientist at Rutgers University. Once the bacteria landed on the glacier's snowy surface, they combined with the snow to form ice. "These ices are actually gene banks," he added. As glaciers and ice caps melt as a result of increasing global warming, large amounts of bacterial genetic material might be washed into the ocean. These bacteria might get incorporated into today's bacteria in the ocean, or living bacteria from the ice might also grow and have an important effect on the ecosystem. "How that's going to play out, we don't know," Bidle said. He and Falkowski plan to focus their future work on how current ice melting influences modem bacteria's genetic diversity. 查看更多

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

  We can make mistakes at any age. Some mistakes we make are about money. But most mistakes are about people. “Did Jerry really care when 1 broke up with Helen?” “When I got that great job, did Jim really feel good about it, as a friend? Or did he envy my luck?” “And Paul - why didn't he pick up that he was friendly just because I had a nice car?” When we look back, doubts like these can make us feel bad. But when we look back, it's too late.

  Why do we go wrong about our friends - or our enemies? Sometimes what people say hides their real meaning. And if we don't really listen, we miss the feeling behing the words. Suppose someone tells you, “Yor're a lucky dog.” That's being friendly. But “lucky dog”? There's a bit of envy in those words. Maybe he doesn't see it himself. But bringing in the phrase “lucky dog” puts you down a little. What he may be saying is that he doesn't think you deserve your luck.

  “Just think of all the things you have to be thankful for” is another noise that says one thing and means another. It could mean that the speaker is trying to get you to see your problem as part of your life as a whole. But is he? Wrapped up in this phrase is the thought that your problem isn't important. It's telling you to think of all the starving people in the world when you haven't got a date for Saturday night.

  How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking. Do his words fit the way he looks? Does what he says agree with the tone of voice? His posture (姿态)? The look in his eyes? Stop and think. The minute you spend thinking about the real meaning behind what people say may save another mistake.
