Question

【題目】閱讀理解
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（軌道） 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】本文是一篇說明文，介紹小飛船撞上彗星1號的實驗，目的是完成首次對彗星的內(nèi)部研究。
（1） 考查細(xì)節(jié)理解。根據(jù)第一段中的”133 million kilometers from Earth.“離地球 1億3300萬公里；第二段中的”The spacecraft was travelling at 37,000 kilometers per hour“宇宙飛船以每小時37000公里的時速行駛，可知從地球到彗星坦普爾1號飛船需要的時間是1億3300萬公里/每小時37000公里，得出結(jié)果大約為3500小時。故選B。
（2）考查細(xì)節(jié)理解。根據(jù)第一段中的”The comet Tempel 1 has an orbit（軌道） far outside the orbit of the furthest planet in our solar system, Pluto. “彗星坦普爾1有一個軌道離我們的太陽系最遠(yuǎn)的行星--冥王星的軌道外面很遠(yuǎn)之外。故選C。
（3）考查詞義猜測。根據(jù)倒數(shù)第二段中的” The aim of the mission was to study for the first time the interior of a comet.“這次任務(wù)的目的是首次對彗星的內(nèi)部研究，故interior是內(nèi)部的意思。故選C。
（4）考查推理判斷。根據(jù)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. “現(xiàn)在我們已經(jīng)失去了一個宇宙飛船，”一位非常高興的美國宇航局工程師說。深的影響就像是美國獨立日的煙火表演。計劃和結(jié)束一個巨大的爆炸花了很多年�？芍�深刻的影響是一個巨大的成功，但科學(xué)家后悔失去了一艘飛船是錯誤的。故選B。
（5）考查推理判斷。根據(jù)第一段中的”Last week a little American spacecraft crashed into Tempel 1.“ 上周，美國小飛船撞上1號。可知本文主要是介紹小飛船撞上彗星1號的實驗，為了完成首次對彗星的內(nèi)部研究，可知作者寫這篇文章的主要目的是介紹一個實驗。故選D。
