It fellthrough the late afternoon Mars’ sky. Forty kilometers above the planet, the thinbegan to slow its fall. Six kilometers above the planet a big parachute(降落伞)opened. The landing craft fell more slowly. Then, three rocket engines. And the landing craft set downon the surface. in the Viking One Lander immediately sent a message to the earth. It said, “I am here. I am down safely. I am beginning my work. ” The messageat the speed of light. It took twenty minutes to reach the earth, more than three hundred and twenty million kilometers. Scientists and engineers at the control center. Moments later, television receiver in the control center began tothe first picture from Viking One. People at the center could see the feet of the landing craft sitting firmly on the 11 soil of Mars. Those pictures were our firstlook at the planet. They showed a red surface, full of rocks, with no sign of. It was our first look at a planet that is full of surprises, mysteries and promise. Viking One was launched toward Mars in August, 1975. The spaceship had two: an orbiter(轨道飞行器)and a lander(着陆器). The orbiter would circleMars. It would take pictures of Mars’ surface. It wouldthe atmosphere. Thewould go down to the surface. It would carryto dig up and study soil and. It also would report about any evidence of life on the planet. The lander would send thisto the orbiter and then back to the earth. 小题1:A.separatedB.appeared C.workedD.started 小题2:A.correctlyB.slowlyC.quicklyD.directly 小题3:A.airB.universe C.spaceD.atmosphere 小题4:A.firedB.fellC.openedD.floated 小题5:A.heavilyB.softly C.suddenlyD.immediately 小题6:A.A computerB.A rocket C.A pilotD.An astronaut 小题7:A.spreadB.traveledC.shotD.moved 小题8:A.farB.longC.distantD.away 小题9:A.shoutedB.watched C.cheeredD.welcomed 小题10:A.makeB.takeC.showD.search 小题11:A.redB.brownC.grayD.black 小题12:A.carefulB.closeC.realD.clear 小题13:A.menB.lifeC.treesD.air 小题14:A.partsB.rocketsC.enginesD.centers 小题15:A.throughB.towardsC.overD.around 小题16:A.enterB.examine C.collectD.discover 小题17:A.orbiterB.lander C.spaceshipD.rocket 小题18:A.engineersB.astronauts C.parachutesD.instruments 小题19:A.surfaceB.treesC.rocksD.pictures 小题20:A.spaceshipB.rocket C.landerD.information 参考答案及解析 小题1:A 小题2:C 小题3:D 小题4:A 小题5:B 小题6:A 小题7:B 小题8:D 小题9:C 小题10:C 小题11:A 小题12:B 小题13:B 小题14:A 小题15:D 小题16:B 小题17:B 小题18:D 小题19:C 小题20:D 【文章大意】文章介绍了“海盗一号”无人宇宙飞船在火星登陆的情况。 小题1:选A。根据文章倒数第三段可知“海盗一号”宇宙飞船由orbiter和lander两部分组成, 到了火星上空两部分分离。 小题2:选C。根据常识判断宇宙飞船应该在飞行时是很快的, 在遇到阻力时才会减速, 这也与后面飞行减缓后的“slowly”相对应。 小题3:选D。thin可以修饰air和atmosphere, 但是只有atmosphere符合语境, 火星的大气减慢它的飞行, 而且与后文也一致。 小题4:选A。rocket的作用就是通过发射把lander送到火星上, 着陆时需要对地面的反推力才不至于着陆太猛。 小题5:选B。因为前面所述的各种措施, 如降落伞、火箭发动机等, 所以是轻轻着陆。 小题6:选A。“海盗一号”是无人载飞船, 所以只能通过电脑发送信息说其在工作。 小题7:选B。根据上下文, message以光速“传播”, spread“扩散”; shoot“发射”; move“移动”。 小题8:选D。表示距离时, 如果有具体的数字, 后面应是away。 小题9:选C。火星登陆成功, 人们欢呼起来, shout“大喊”; watch“看”; welcome“欢迎”。 小题10:选C。在屏幕上show“显示”发送回来的图片, 其他三项意思不符。 小题11:选A。火星上的土壤是红色的, 所以后面第二句提到红色的火星表面。 小题12:选B。这些照片是在火星上拍摄的, 所以是close look“近看”, real不修饰look。 小题13:选B。根据常识可知, 火星上没有生命的迹象, 更没有树和人。 小题14:选A。宇宙飞船有两部分, 由下一句话可得知答案。 小题15:选D。circle around Mars环绕火星飞行。 小题16:选B。examine指“检验”。enter“进入”, collect“收集”, discover“发现”都不合适。 小题17:选B。由上文可知, 宇宙飞船分两部分, 前面介绍了orbiter, 这里介绍lander。 小题18:选D。在火星上, “海盗一号”只能通过一些科学仪器对火星上的土壤和岩石进行检验。 小题19:选C。由前文中“full of rocks”可知答案。 小题20:选D。着陆器把在火星上得到的信息传给轨道飞行器, 然后传到地球上来。 相关资料 |
