American Race to the Moon
The roots ofAmerica’s plan to land a man on the moon can be found outside of the country.Although never directly mentioned in its official motto, the NationalAeronautics and SpaceAdministration (NASA、was established as a direct result of the Soviet space program’s successful launching of Sputnik 1, the first man-made satellite, on October 4th, 1957. The U.S.Congress, worrying that the country was about to lose its technological edge over the rest of the world, demanded drastic action.Dwight
D、Eisenhower, then president, waited only a few months before creating a new government agency responsible for all non-military activity in space. On July 29th, 1958, the president signed the NationalAeronautics and SpaceAct, creating NASA、The outside world continued to have an effect. The technology initially used by NASA、came in large part from the German rocket program of the Second World War. Wernher vonBraun, who was recruited by theAmericans at the end of the war, is today considered the father of the United States space program.
NASA、began operations on October 1st, 1958, and was made up of four laboratories as well as about eight thousand employees from the already 43-year-old NationalAdvisoryCommittee forAeronautics. The history of the new organization can be divided into various phases, each related to a specific program. The first experiments undertaken as part of Program Mercury were designed simply to discover if humans could actually survive a round-trip voyage into space. This involved the construction of 20 spacecraft, each large enough to hold one astronaut. On a very basic level, NASA、needed to test what worked and what didn’t. They made numerous unmanned launches, many of them resulting in explosions, as well as four separate launch attempts that included small creatures. The first was a small monkey.By 1961, NASA’s Program Mercury successfully placedAlan Shepard into space, but for only fifteen minutes.
This milestone quickly led to theApollo Project. The initial idea was to get a human close to the Moon, but not actually on it. There were too many unknowns about the surface of the Moon to plan a safe landing. On February 20th, 1962, John Glenn piloted the Friendship 7 for five hours in orbit around theEarth. NASA、had finally learned how to get a human into space, and most importantly, keep him there. This was the crucial step necessary: they had created the ability to stay in space long enough to really figure out what to do there. The objectives of the mission changed drastically, however, when President JohnE、Kennedy told the nation on May 25th, 1961, thatAmerica would instead focus on a manned mission to and from the Moon, and that these missions would be possible by the end of the decade.

A、Many people worried about the money that would be spent, feeling that it would be better used for other purposes. ■
B、Others continued to see the program in relation to the rest of the worl
D、■
C、They worried that NASA、did not seem to have any valuable military use and openly questioned the idea of spending money on rockets that could not be used to defend the country. ■
D、Kennedy managed to convince both sides of the project’s benefits. He assured people that the mission would provide jobs and resources to different states throughout the country as well as specific advances in rocket technology. Kennedy stressed the value of dual-use technology, which could be used for both military and non- military purposes.
Instead of sending a person to space and back again, which required only one lift-off fromEarth followed by a landing, theApollo Project now entailed anEarth lift-off, followed by a landing on the Moon, another lift-off, and then a finalEarth landing. The Gemini Program, therefore, was created to collect information and perfect techniques that would make theApollo Project possible. U

[解析] 句子简化题 向月球发射载人宇宙飞船的计划遭到了很多人的反对和质疑,而这句话是肯尼迪为了说服国民所说的内容。他的理由之一就是这个计划可以解决很多人的就业问题,此外也可以发展火箭技术。B项的后半部分是错误的,C项和D项将两个信息错误地组合到一起,歪曲了原意。A项将原文中的as well as换成了and,用“取得科研突破”代替了“发展火箭技术”,意思基本没有变化。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
