答案Ⅰ.閱讀理解A語(yǔ)篇解讀地球適合人類生存在于它有足夠的氧氣、適宜的溫度等?？茖W(xué)家發(fā)現(xiàn)火星存在適合人類生存的條件。1.答案B解析細(xì)節(jié)理解題。根據(jù)第一段中的第四句和第二段中的最后兩句可知，地球是可證實(shí)的唯一有生命存在的太陽(yáng)系行星，其原因包括地球合適的溫度、與太陽(yáng)距離適中和大氣里含有氧氣等。B項(xiàng)中的火山與此無(wú)關(guān)。2.答案C解析詞義猜測(cè)題。根據(jù)第一段內(nèi)容可知距離太陽(yáng)第三遠(yuǎn)的行星指的是地球。3.答案A解析推理判斷題。從最后一段中的“...dried-upriverbeds”和最后兩句可知，火星上有干涸河床的跡象，但這一點(diǎn)并不能證實(shí)火星上存在過(guò)生命，因?yàn)闆](méi)有發(fā)現(xiàn)生命跡象，故A項(xiàng)不正確。其他三項(xiàng)都與文章相符。B語(yǔ)篇解讀飛行員Glenn是第一個(gè)坐宇宙飛船繞地球飛行的美國(guó)人。他拒絕別人把他當(dāng)作英雄，他認(rèn)為致力于有意義的事情的人是最幸福的。4.答案D解析細(xì)節(jié)理解題。根據(jù)第三段最后一句可知，他成為第一個(gè)坐宇宙飛船繞地球飛行的美國(guó)人。故選D。5.答案B解析細(xì)節(jié)理解題。根據(jù)第三段中的“AfaultyequipmentledGlenntobelievethecapsulemightburnuponitsretur
