题目解答
答案
6. C 7. D 8. B
解析
考查要点：本题组考查中国探月工程系列任务的关键成就，涉及嫦娥系列探测器及鹊桥卫星的作用。
解题核心：需明确各探测器的任务目标及技术突破，结合时间顺序判断。
关键点：
- 首次月球软着陆：需区分嫦娥系列不同任务的里程碑意义。
- 鹊桥卫星的功能：理解中继卫星在月球背面通信中的作用。
- 嫦娥-4的特殊性：明确“月球背面软着陆”这一全球首次成就。
第6题
关键思路：嫦娥系列任务中，嫦娥-3号是首次实现月球软着陆的探测器。
- A. 嫦娥-1：2007年发射，主要任务为绕月探测，未着陆。
- B. 嫦娥-2：2010年发射，为后续任务试验技术，仍属于绕月任务。
- C. 嫦娥-3：2013年发射，首次实现月球表面软着陆，携带“玉兔”月球车。
- D. 嫦娥-4：2018年发射，首次在月球背面软着陆，但非首次整体软着陆。
第7题
关键思路：鹊桥卫星是专为月球背面通信设计的中继卫星。
- A. 地形勘测：此为嫦娥-4着陆前的预选工作，由轨道器完成。
- B. 备份功能：鹊桥卫星与探测器无直接功能关联。
- C. 搭载仪器：中继卫星主要负责通信，不承担科学探测任务。
- D. 通信链路：月球背面无法直接与地球通信，鹊桥卫星填补这一空白。
第8题
关键思路：嫦娥-4首次实现月球背面软着陆，属全球首次。
- A. 搭载生物实验：确有“月面微型生态圈”实验，但非独特成就。
- B. 月球背面软着陆：人类探测器首次实现，具有里程碑意义。
- C. 人类首次目视月球：此成就属于阿波罗登月任务。
- D. 国际合作载荷：虽有搭载，但非嫦娥-4的核心突破。
