　　【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。
