M: Doctor Cole, thank you for agreeing to this interview for the Daily Campus News. Can you tell us about what you and your colleagues discuss at the annual astronomy society meeting last month?
W: Yes. For the first time ever the scientific community has established the existence of planets outside our own solar system. Of course we knew that certain distant stars existed, but only recently did we learn that several of them are orbited by their own planets.
M: Why did it take so long to locate these planets?
W: Well, you have to understand that they are a billion times dimmer than their parent stars. It would be like trying to see the light of a candle next to a huge explosion. We don’t currently have a telescope that can be used to see them.
M: But if the astronomers didn’t see the planets through a telescope, how did they find them?
W: By a very indirect method. The astronomers measured subtle distortions in the frequency of the light from the parent stars and observed that some of the stars seem to rock back and forth. They determined that this was caused by gravitational pull from orbiting planets.
M: There is a powerful new telescope being built in Arizona. Will that help them see these planets?
W: They should be able to see them at least in the form of small spots of light. And then the scientists will be able to break down and analyze this light. By doing this, they hope to learn about the chemical composition of these planets—oxygen and ozone molecules, for example, would be telltale signs of life on these planets.
M: I’m looking forward to hearing more when the telescope is in operation. And I’m sure our readers would be interested too.
选项

B、Their chemical composition.
C、Their temperature.
D、Their age.
答案
B
解析
信息明示题,女士说科学家们可以利用新的望远镜来分解、分析光线,进而希望了解这些行星的化学成分,故选B,考点 break down 此处意为“分解,分为(…项)”,还有以下含义:①停止运转,失效,如:The engine broke down.引擎坏了,②失败,瓦解,如:The peace talks have broken down. 和平会谈破裂了,③感情失去控制,如:He broke down and wept when he heard the bad news.他听到坏消息时不禁痛哭起来
