题目：
Scientists do not understand why women should outlive men by five years.
答案：
参考答案：错
解析：[听力原文]A man is in his best shape in the decade before age 25 when his muscles are firmest, his resistance to colds and infections is highest and his body is most efficient in utilizing nutrients. For reasons that scientists do not understand, women get a five-year bonus.
[分析]： 数字信息的找寻和判断。 根据原文可知，男人在25岁以前的10年中身体状态、各项机能处于最高峰，但不知为什么，women get a five-year bonus 即女人的高峰时期比男人还多五年。由此可见，原文并未讨论女性寿命比男性长的问题。因此，题干的说法与原文不符。[解题关键] 能够将关键信息总结归纳。如将本题中几个最高级表达firmest，highest和 most efficient总结归纳，可知本段主题讨论身体最佳状态或身体机能的高峰，显然与题干中关键词outlive“比……活得长”不符。
