题目解答

答案

解析

考查要点：本题主要考查学生对文章主旨、词汇理解、细节推理及标题归纳能力的掌握。
解题思路：

  1. 定位关键时间点（如第56题）需结合历史背景与事件因果关系；
  2. 词义猜测（如第57题）需结合上下文语境推断短语含义；
  3. 主旨归纳（如第58、59题）需抓住文章核心论点，即运动的健康益处及其科学依据。

第56题

关键信息：文章首段提到“Exercise as a part of daily life did not catch on until the late 1960s when research by military doctors began to show the health benefits of doing regular physical exercise.”
推理过程：

  • 时间顺序：运动成为日常生活的组成部分是在军事医生研究显示健康益处后发生的。
  • 选项对比：A选项“研究显示健康益处”直接对应文中时间点，其他选项（如B、D）是后续现象，非起因。

第57题

关键信息：原文“running has levelled off in recent years”后解释原因“Americans have discovered equally rewarding-and sometimes safer-forms of exercise”。
词义推断：

  • 语境分析：跑步不再增长（因被其他运动取代），而非完全消失或达到最低点。
  • 选项匹配：D选项“停止增加”最符合语境。

第58题

关键信息：文中多次强调“scientific evidence of health benefits”（如第2段末尾）。
推理过程：

  • 直接引用：文章明确指出健康益处有科学依据，C选项“被科学证据支持”与原文一致。

第59题

关键信息：文章核心论点为运动对健康的益处及其科学性（如“key to fitness”“improvements in physical health”）。
标题归纳：

  • 主旨提炼：B选项“Exercise—The Road to Health”最能概括文章主旨，其他选项（如A、D）仅涉及部分细节。
