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
A、They studied variations in the appearance of the parent stars.
B、They compared the parent stars to the Sun.
C、They were able to see the planets with a telescope.
D、They sent astronauts on a mission into space.
答案
A
解析
综合推断题,女士说天文学家是通过间接方法来发现那些行星的,他们测量出母星发出的光频的细微变化,还观察到母星似乎前后摆动,最终确定这都是由于沿轨道运行的行星的牵引而引起的,由此推断,科学家们是通过研究母星外观的变化来确定行星的存在的,故选A
