11.写奥茨走向死亡，其他人不敢劝阻，这和上文他们表现出来的集体主义精神是否矛盾？为什么？【答案】不矛盾。这里不敢劝阻，并非胆怯，而是因为令人绝望的无助和无奈。面对漫天的暴风雪，所有人都自身难保，对奥茨也爱莫能助。奥茨选择英雄式的死亡，大家只能理解、尊重他的选择。
12. “心中的海市蜃楼”指什么？这样表达有何作用？【答案】本题运用关键词语表达效果法。“心中的海市蜃楼”是指斯科特在离开世界前心中回忆的美好的往事和他对遥远的祖国、亲人和朋友的怀想。它们与严酷的现实形成了鲜明的对照，海市蜃楼是美好的，却是根本无法实现的，这更加增强了悲剧效果，给人以心灵的冲击。
3.“千万年来”“太古以来”“一个月内”三个表示时间的词语有什么作用？
【答案】 “千万年来”“太古以来”与“一个月内”形成对比，写出阿蒙森和斯科特两支探险队惊人的壮举。 “一个月内”也表示斯科特一行晚了一个月，为下文的悲剧作铺垫。
4.结合文段思考，“对人类来说，第一个到达者拥有一切，第二个到达者什么也不是”这句话作者要表达的意思是什么？作者同意这种说法吗？【答案】这句话是作者站在斯科特的角度来写的，表达了斯科特在角逐失败后的一种极度沮丧、悲哀的心情。但事实上作者本人并不这么认为，因为作者为斯科特这个失败者作传，本身就说明作者不同意“第一个到达者拥有一切，第二个到达者什么也不是”这一说法。
1．以时间为顺序，条理清晰。课文记叙了斯科特探险队一行五人历尽艰难、满怀希望地奔向南极点，却悲哀地发现已经有人捷足先登，只好垂头丧气地踏上归途，最后一个个悲壮死去的故事。文章按照时间顺序逐一叙述，条理清晰。 2．出色的细节描写。文中多处运用细节描写，充满感情。比如，奥茨用冻掉了脚趾的脚板行走；再如，威尔逊博士在死亡的边缘仍坚持科学观察，并在极度艰难的情况下，拖着16公斤的珍贵岩石样品！这些细节描写表现了作者对他们的赞美之情，同时感动了所有的读者。
