Question

【题目】阅读理解
For thousands of years comets have been a mystery to man. They travel across the sky very fast and have a bright “tail” of burning gas. The comet Tempel 1 has an orbit（轨道） far outside the orbit of the furthest planet in our solar system, Pluto. It has been there for 4.6 billion years, 133 million kilometers from Earth. Last week a little American spacecraft crashed into Tempel 1. The spacecraft had a camera and it took a photograph of the comet every minute before it finally crashed into its surface.
The space mission to Tempel 1 cost $335 million and was called Deep Impact. The spacecraft was travelling at 37,000 kilometers per hour when it hit the comet and the crash completely destroyed the spacecraft. But before it hit the comet, the spacecraft took some amazing photographs. The last one was a close-up picture which the spacecraft took just 3 seconds before it crashed into the comet.
“Right now we have lost one spacecraft,” said a delighted NASA engineer. Deep Impact was like a American Independence Day fireworks display. It took many years to plan and ended in an enormous explosion.
The spacecraft which crashed into the comet was made of copper and was the size of a washing machine. It was dropped from a mothership into the path of the comet and the mothership then photographed the cloud of ice, dust and organic chemicals that rose from the surface of the comet after the crash.
The crash completely destroyed the spacecraft but nothing really happened to the comet: experts believe that the crash slowed the comet down by no more than 1/10,000 of a millimeter a second.The aim of the mission was to study for the first time the interior of a comet.
The mothership was 480 km from the explosion and observed the crash and the explosion with instruments for 800 seconds. Seven satellites, including the Hubble space telescope, watched the moment of drama, and over the next day and night about 50 telescopes on Earth were watching the distant comet.
（1）How many hours did it take for the spacecraft from the earth to touch the comet Tempel 1?
A.About 2,500
B.About 3,500
C.About 4,500
D.About 5,500
（2）Which of the following shows the possible orbits and positions of the comet Tempel 1?
S=solar P=Pluto T= Tempel
A.
B.
C.
D.
（3）Which of the following is the closest in meaning to the underlined word in Paragraph 5?
A.position.
B.relation.
C.inside.
D.distance.
（4）Which of the following is NOT true according to the passage?
A.The name of the space mission is called Deep Impact.
B.Deep Impact was a fantastic success but the scientist regretted losing a spaceship.
C.The crash didn't have much effect on Tempel 1.
D.The aim of the mission was to study the interior of a comet.
（5）The author's main purpose in writing the passage is to ____________.
A.inform people the discovery of a new comet
B.show the power of America in space.
C.introduce the knowledge of comets
D.introduce an experiment

Answer 1

【答案】
（1）B
（2）C
（3）C
（4）B
（5）D
【解析】本文是一篇说明文，介绍小飞船撞上彗星1号的实验，目的是完成首次对彗星的内部研究。
（1） 考查细节理解。根据第一段中的”133 million kilometers from Earth.“离地球 1亿3300万公里；第二段中的”The spacecraft was travelling at 37,000 kilometers per hour“宇宙飞船以每小时37000公里的时速行驶，可知从地球到彗星坦普尔1号飞船需要的时间是1亿3300万公里/每小时37000公里，得出结果大约为3500小时。故选B。
（2）考查细节理解。根据第一段中的”The comet Tempel 1 has an orbit（轨道） far outside the orbit of the furthest planet in our solar system, Pluto. “彗星坦普尔1有一个轨道离我们的太阳系最远的行星--冥王星的轨道外面很远之外。故选C。
（3）考查词义猜测。根据倒数第二段中的” The aim of the mission was to study for the first time the interior of a comet.“这次任务的目的是首次对彗星的内部研究，故interior是内部的意思。故选C。
（4）考查推理判断。根据第三段中的“‘Right now we have lost one spacecraft,’ said a delighted NASA engineer. Deep Impact was like a American Independence Day fireworks display. It took many years to plan and ended in an enormous explosion. “现在我们已经失去了一个宇宙飞船，”一位非常高兴的美国宇航局工程师说。深的影响就像是美国独立日的烟火表演。计划和结束一个巨大的爆炸花了很多年。可知深刻的影响是一个巨大的成功，但科学家后悔失去了一艘飞船是错误的。故选B。
（5）考查推理判断。根据第一段中的”Last week a little American spacecraft crashed into Tempel 1.“ 上周，美国小飞船撞上1号。可知本文主要是介绍小飞船撞上彗星1号的实验，为了完成首次对彗星的内部研究，可知作者写这篇文章的主要目的是介绍一个实验。故选D。
