12月14 日21时11分, 嫦娥三号探测器在高真空的月球表面预选着陆区域成功着陆,标志我国已成为世界上第三个实现地外天体软着陆的国家。完成下列各题

小题1:探测器软着陆月面有难度,主要原因是

A.真空-----无法用降落伞减速

B.太阳风-----容易吹倒月球车

C.地形起伏大-----角峰、火山锥林立

D.低温-----当地季节为冬季小题2:科学家建议给未来的月球系一根“腰带”(长1.1万公里,宽400公里)以获取资源,然后用激光或微波把该资源传回地球,该资源应是

A.太阳能

B.风能

C.核能

D.闪电

答案

小题1:A 

小题2:A

题目分析:

小题1:探测器软着陆月面就是指探测器无损伤的降落到月面上,探测器如何由高速撞向月球的硬着陆,转变成可控状态下的安全无损的软着陆,其关键技术应该在制动减速上。像飞机、返回舱等航空、航天器在地球上着陆时常用减速伞,可月球上的真空环境,无法用减速伞,只能探索新的减速方法。选项A正确。

小题2:在四个选项中,月球上能有的资源只有太阳能和核能,在太阳能和核能中能用激光或微波传回地球的只有太阳能了,选项A正确。
