阅读奥义：三查法
认识单词 ≠ 看懂句子。看懂句子 = 三步：① 找动词主干 ② 介词多 = 逻辑关系 ③ 代词多 = 定语从句指代。
一、三查法
- 查动词（找主干）：先划出谓语动词 → 谁干了啥 / 谁是谁
例句：The Babylonians began to measure time, introducing calendars to co-ordinate communal activities.（其余全是"挂件"） - 查介词（定逻辑）：on/above 不接触、around 围绕、through 穿过、for 目的、of 所属
例句：it organised its activity chart around the solar year（around = 围绕） - 查代词（回指）：which/that/who/in which 往左找名词 = 先行词，往右读动词 = 从句内容
例句：the system in which each interval of darkness was divided into a dozen equal parts
句子特征预判：介词多 = 找句子结尾单词，用介词知道彼此之间的逻辑关系；代词多 = 定语从句密集，逐个往左回指。
二、实战：A Chronicle of Timekeeping（时间测量史）
长难句：According to archaeological evidence, at least 5,000 years ago…the Babylonians began to measure time, introducing calendars to co-ordinate communal activities, to plan the shipment of goods and to regulate planting and harvesting.
- 主干：Babylonians began to measure time；三个 to do = 日历的三个目的
- 三个自然周期并列：the solar day（marked by…）；the lunar month（following…）；the solar year（defined by…）——冒号后各挂分词 = 定语压缩
时间轴（本篇考点地图）
- Babylonians 5000 年前引入日历（纬度影响：低纬重月、高纬农区重太阳年）
- Egyptians：12×30 天 + 5 天；decans 划分 12 段 → temporal hours（随季节长短变化）
- sundials（白天）/ water clock（夜晚，北欧阴天失效）→ 机械钟 1283：escapement 擒纵器是革命点 → anchor escapement（1670）→ 长摆 → grandfather clock
- 现代：石英钟 → GPS 授时（"时间技术失效才被察觉"是出题人爱考的结尾）
三、作文里的三查（educational shift 批改示范）
- 非限定 which 是补充，不是递进：which enables them to improve… 可拿出来做单独句 → 递进要用 These 代词开新句
- including vs such as：如果是"能力类型清单"用 such as 更合适
- 下探深度：practical skills → competence in these areas is in high demand in today's job market
- 复合词：N+现在分词（time-saving）；N+过去分词（hand-made / machine-made / solar-powered / profit-driven）
