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，F(xiàn)lorida．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．

分析 這篇短文主要介紹了在2013年發(fā)射的一艘火星探測(cè)器-MAVEN飛船及發(fā)射目的、時(shí)間、地點(diǎn)和到達(dá)火星后的任務(wù)等．
解答 DCAB
32．D 推理判斷題．根據(jù)第一段"Since the 1960's，…all that water disappeared when the planet lost its air．"可知人類現(xiàn)在已經(jīng)更了解火星了．故選D．
33．C 細(xì)節(jié)理解題．根據(jù)第二段"NASA had launched the MAVEN spacecraft in the hope of answering that very question．"可知發(fā)射這個(gè)探測(cè)器是為了解決一個(gè)問(wèn)題．根據(jù)第一段"But why did the atmosphere on Mars change so greatly？"可知這個(gè)問(wèn)題是"火星的空氣變化為什么如此之大？"故選C．
34．A 推理判斷題．根據(jù)最后一段描述，可知隨著這個(gè)探測(cè)器在火星著陸，更多關(guān)于火星的信息將會(huì)被傳遞回來(lái)．因此我們將會(huì)發(fā)現(xiàn)更多關(guān)于火星的奇妙的事情．故選A．
35．B 主旨大意題．這篇短文主要介紹了MAVEN飛船的目的，發(fā)射的時(shí)間地點(diǎn)，以及到達(dá)火星后的任務(wù)等，故本文最佳標(biāo)題為在2013年發(fā)射的一艘火星探測(cè)器．故選B．
點(diǎn)評(píng) 閱讀理解題測(cè)試考生在閱讀基礎(chǔ)上的邏輯推理能力，要求考生根據(jù)文章所述事件的邏輯關(guān)系，對(duì)未說(shuō)明的趨勢(shì)或結(jié)局作出合理的推斷；或根據(jù)作者所闡述的觀點(diǎn)理論，對(duì)文章未涉及的現(xiàn)象、事例給以解釋．考生首先要仔細(xì)閱讀短文，完整了解信息，準(zhǔn)確把握作者觀點(diǎn)．
