题目解答
答案
解析
考查要点：
- 细节理解：根据文章内容定位具体信息，如睡眠袋的放置位置、词语含义等。
- 词义猜测：通过上下文推断“watch over”的具体含义。
- 时间计算：提取文中明确给出的数字信息。
- 主旨归纳：通过文章细节总结整体主题。
解题核心思路：
- 直接定位法：小题1、3可通过关键词（如“sleeping bags”“orbit”）快速定位答案。
- 逻辑推理法：小题2需结合上下文（工程师和计算机负责监控）推断词义。
- 主题词串联法：小题4需整合文章中“sleeping bags”“sleep-time”“fall asleep”等关键词概括主旨。
小题1
关键句：
At bedtime we untie them and take them wherever we’ve chosen to sleep.
解析：
文中明确说明宇航员在睡觉时会将睡袋带到自己选择的任何地方，因此答案为 D。
小题2
关键句：
No one has to stay awake to watch over the space-plane; the shuttle’s computers and the engineers at Mission Control do that.
解析：
“watch over”表示“监控、看护”，而下文提到计算机和工程师负责“do that”，即“监控航天飞机”。选项中 D（take care of） 最接近此含义。
小题3
关键句：
During each ninety-minute orbit the sun “rises” and shines through our windows for about fifty minutes...
解析：
文中直接提到航天飞机绕地球一圈需要 90分钟，对应选项 C。
小题4
关键句：
Sleep-time doesn’t mean nighttime... It is surprisingly easy to get comfortable and fall asleep in space...
解析：
文章围绕“太空船中的睡眠”展开，详细描述了睡眠袋的使用、作息规律、睡眠环境等，因此最佳标题为 A（Sleeping in the Space Shuttle）。
