Question

2．Mars was the first planet that humans attempted to get to．Since the 1960's，scientists have be en working to learn more information about the Mars'past，We now know that Mars was once a warm，wet place with great oceans and deep rivers．We also know that about 3.7 billion years ago，all that water disappeared when the planet lost its air．But why did the atmosphere on Mars change so greatly？
NASA had launched the MAVEN spacecraft in the hope of answering that very question．MAVEN will study the remains of Mars'air and help scientists figure out what became of the rest of it．
The spacecraft was launched on Monday，November 18，2013，from Cape Canaveral，Florida．The trip to Mars takes about 10 months，and MAVEN is scheduled to go into orbit in September 2014．It is the first spacecraft created with the purpose of studying Mars'atmosphere．Its wings measures 37.5 feet not quite the length of a school bus，and it weighs 1991 pounds about the sa me amount as a small car．MAVEN is equipped with eight different tools to measure and study the planet's atmosphere．To collect information，it will fly in orbit as fast as 3278 miles per hour，and as slow as 93 miles per hour．
Once it arrived at Mars，MAVEN will have plenty of company．The spacecraft Curiosity is still walking around the planet's rocky surface，studying the geology，chemistry and possible biology there．NASA currently has a number of spacecrafts getting unique views of Mars with powerful cameras and telescopes．These missions are all slow，steady steps forward to discover Mars secret past．While the results may not be revealed for some time，an exciting exploration is on the way．

Answer 1

分析 这篇短文主要介绍了在2013年发射的一艘火星探测器-MAVEN飞船及发射目的、时间、地点和到达火星后的任务等．

解答 DCAB
32．D  推理判断题．根据第一段"Since the 1960's，…all that water disappeared when the planet lost its air．"可知人类现在已经更了解火星了．故选D．
33．C  细节理解题．根据第二段"NASA had launched the MAVEN spacecraft in the hope of answering that very question．"可知发射这个探测器是为了解决一个问题．根据第一段"But why did the atmosphere on Mars change so greatly？"可知这个问题是"火星的空气变化为什么如此之大？"故选C．
34．A  推理判断题．根据最后一段描述，可知随着这个探测器在火星着陆，更多关于火星的信息将会被传递回来．因此我们将会发现更多关于火星的奇妙的事情．故选A．
35．B  主旨大意题．这篇短文主要介绍了MAVEN飞船的目的，发射的时间地点，以及到达火星后的任务等，故本文最佳标题为在2013年发射的一艘火星探测器．故选B．
