Passage TwoQuestions 19 to 21 are based on the conversation you have just heard.
A. The sleep a person needs varies from day to day.
B. The amount of sleep for each person is similar.
C. One can get by with a couple of hours of sleep.
D. Everybody needs some sleep for survival.
题目解答
答案
D. Everybody needs some sleep for survival.
解析
本题考查对听力材料主旨的把握，需要根据对话内容判断关于睡眠需求的核心观点。关键点在于识别材料中强调的“睡眠对生存的必要性”，而非具体睡眠时长或个体差异。选项D直接对应材料中“每个人生存都需要一定睡眠”的核心结论。
选项分析
选项D正确，因为材料中明确提到睡眠是人类生存的基本需求，所有人都需要足够的睡眠来维持正常功能。
- 排除A：材料未提及睡眠需求“每天不同”，而是强调普遍性需求。
- 排除B：材料指出个体睡眠需求存在差异，与“相似”矛盾。
- 排除C：材料否定“仅需少量睡眠”，强调必须保证充足睡眠时间。
