Question

【题目】请阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。
D
On May 18, 1969, NASA astronauts Thomas Stafford, John Young, and Eugene Cernan boarded the Apollo 10 lunar module(登月舱)---the fourth manned mission in the US Apollo Space program and only the second after Apollo 8 to circle the moon. Its mission was to circle the moon and thoroughly test the components and procedures to pave the way for the first lunar landing. The mission went perfectly without incident---at least that's what every one believed.
However, that view has changed since February 22, after NASA released a digital recording of strange music heard by the space travelers. Then as they were re-entering the zone where they could communicate with ground control. One of the astronauts asked if they should report it. In response, Stafford expressed his doubts if anyone would even believe them. But they needn't have worried. When NASA experts listened to the recordings, they thought the strange sounds were radio interference.
Michael Collins---the Apollo 11 pilot---said that the only reason why he was not shocked upon hearing them was that he had been forewarned by NASA officials. Collins also said that the music stopped as soon as the lunar module landed on the moon.
So why did it take NASA over 40 years to release the digital recording of the awful music only after it was featured in a recent television series NASA's Unexplained Files? The US Space Agency says they have not been hiding them. In the press release that accompanies the release of the recording, NASA officials state, “The Apollo 10 audio clips were uploaded in 2012, but the mission's sound recordings have been available at the National Archives for anyone that wanted to hear them since the early 1970s.”
Eugene Cernan. Apollo 10's pilot who heard the sounds first, also released a statement saying, “I don't remember that incident excited me enough to take it seriously. It was probably just radio interference. Had we thought it was something other than that, we would have briefed everyone after the flight. We never gave it another thought.”
While most people are ready to accept this logical explanation, there are some that believe otherwise. They guess the music proves the presence of aliens. Among them is Apollo 15 astronaut Al Worden, who thinks the sounds came from a source in outer space. In the episode of NASA’s Unexplained Files, which discusses the origin of the strange music, the astronaut says, “Logic tells me that if there was something recorded on there, then there was something there.”
（1）Apollo 10's mission was to________.
A.take the astronauts to the moon

（2）When the astronauts heard the sounds, ________.
A.they were excited about the discovery
B.they reported to NASA at once
C.they were heading back to the lunar ground
D.they thought they might be of little importance
（3）According to the passage, ________.
A.the mission of Apollo 10 turned out to be unsuccessful
B.NASA made the TV series to clarify some space-related mysteries
C.Al Worden on Apollo 15 believes in aliens and logic
D.Michael Collins knew about the strange sounds before his flight
（4）What is the main idea of this passage?
A.A TV program was released about NASA’s unexplained files.
B.The music heard by Apollo astronauts could be radio interference.
C.The existence of aliens still remains a question.
D.Apollo astronauts heard strange sounds from outer space.

Answer 1

（2）D
（3）D
（4）B
【解析】本文讲的是On May 18, 1969,美国宇航员登上月球，发现竒怪的声音，认为这竒怪的声音很可 能是收音机的干扰。
（1）C 细节理解题。根据第一段第二句 Its mission was to circle the moon and throughly test the components and procedures to pave the way for the first lunar landing.它的使命是环绕月球并彻底测试组件和程序，为第一次月 球登陆铺平道路。故选C。
（2）D推理判断题。根据第二段最后一句 When NASA experts listened to the recordings, they thought the strange sounds were radio interference.他们认为这竒怪的声音是收音机的干扰可知他们认为他们可能没有什么重 要性。故选D。
（3）D 细节理解题。根据第三段第一句 Michael Collins---the Apollo 11 pilot—said that the only reason why he was not shocked upon hearing them was that he had been forewarned by NASA officials. Michael Collins听到奇怪的声音并不震惊是因为NASA官员已经告诉他了。故选D。
（4）B主旨大意题。根据第五段中It was probably just radio interference.这竒怪的声音很可能是收音机的干扰。故选B。
