Question

When Geoff Marcy was 14, his parents bought him a telescope. Every night, he would go onto the roof outside his window to see the wonders of the sky.
“What excited me most was whether there were planets in other solar systems where life might exist,” he says. “I decided to try to find planets orbiting other stars like our Sun.”
And he did. “My fellow researcher, Paul Butler, and I found our first planet in 1995,” Dr. Marcy says. “We worked for ten years without finding anything! But we stuck with it and our patience paid off.”
Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other stars. Dr. Marcy and Dr. Butler also spotted the first “family” of three planets. In June 2002 they announced another discovery: a Jupiter-like planet orbiting star 55Cancri.
At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55Cancri is a major breakthrough: it is the first sighting of a large gas planet about same distance from the star as Jupiter is from the Sun.
Why is this important ? Scientists think that life on Earth may exist because of two special features in our solar system. The first is Jupiter.
“Because it’s so big, Jupiter pulls comets and asteroids(小行星), or they all come and hit the Earth.” Dr. Marcy explains. “Without Jupiter , life on Earth would likely have been destroyed.”
A second feature is that Earth is a rocky planet where liquid water, which is necessary for life , can exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life. A huge space exists between the Jupiter-like planet and two other planets that lie close to 55Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so, says Dr. Marcy, “We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life!”

试题分析：文章介绍Geoff Marcy从小就对探索太空中的生命感兴趣，他和同事Paul Butler一起努力探索，发现了66个新的行星而且还发现两个和太阳系很相似的星系，从而证明太空有可能有生命的存在。
1.推理判断题。根据第二段的首句“What excited me most was whether there were planets in other solar systems where life might exist,”可知他对探索太空中的生命感兴趣。选D
2.细节题：根据第五段的最后一句The planet orbiting 55Cancri is a major breakthrough: it is the first sighting of a large gas planet about same distance from the star as Jupiter is from the Sun.可知这个行星是一个气状体的行星。选C
3.细节题：从第三段的句子：And he did. “My fellow researcher, Paul Butler, and I found our first planet in 1995,” Dr. Marcy says. “We worked for ten years without finding anything!可知他们是在1995年发现新的行星的，但是他们努力了10年了，所以是1985年开始寻找新行星的，选B
4.推理判断题。根据最后一段的We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life!”可推出在太空中可能存在两个类似于太阳系的星系，可能会有生命存在。选A
5.词义理解题：从第三段的句子：“We worked for ten years without finding anything! 可知“But we stuck with it”是“继续”的意思，选B
