做题顺序（四步法）：　准备——给每段标上序号（只数段，不读文）；　第 1 步 只看题干，圈题型；　第 2 步 回原文划依据句、填段落号；　第 3 步 长难句攻关；　第 4 步 正式作答。　全部做完才翻页核对——答案页在背面，翻页前不许偷看。
原文（段号自己标：在每段开头写 1 2 3……——只数段，不读文）

The peak of Mount Qomolangma, 8,849 meters above sea level. Chimborazo, 6,263 m; Mont Blanc, 4,806 m; Pradidali hut, at the foot of the Pala group in the Dolomites, 2,278 m. It is common practice to provide the elevation (高度) of a place. Simple readings are now readily available on our phones and wearables. But elevation is necessarily relative: only the choice of a reference point allows us to express numerically the height of an object or a location.

The idea of sea level as a reference point for elevations has by now been around for so long as to go essentially unnoticed — we mention it without even considering what it means. That the concept has a history is easily ignored. We tend to forget that sea level is a product of technically and culturally determined assumptions. In this book, I tell a story of these assumptions.

Appropriately, the book took shape during a summer spent between sea and mountains. A month after visiting the French Riviera and enjoying the sandy beaches of Nice and Menton, I went hiking with friends in the Pala group. Resting on a pass near the Pradidali hut, we began discussing the readings offered by our altimeters (测高仪). Why did they vary ever so slightly from one instrument to the next? This sense of uncertainty led me to think about the meaning of zero. This is how I began my search for the conceptual history of sea level.

In this book I examine three crucial stages in the history of mean sea level. These stages mirror the development of human conceptions of the sea. Since I began thinking about this project in August 2011, the issue of sea-level rise and the need to place it historically have only become more urgent: between then and the end of 2022 the global sea rose by almost 5 centimeters, about half of the overall rise recorded by satellites since 1993.

28. What does the author point out at the beginning of the text?
A. Some mountains are getting higher.B. Data on wearables are misleading.C. The concept of elevation is relative.D. The reference point is hard to locate.
29. What is paragraph 3 mainly about?
A. How the altimeter was invented.B. What initiated the author's research.C. Why the digital readings varied.D. Where the author spent his holiday.
30. What does the underlined word "it" refer to in the last paragraph?
A. The book.B. The project.C. The issue.D. The development.
31. What can be the title of the book mentioned in the text?
A. The Altimeter: A Must-Have.B. Sea Level: A History.C. Meaning of Zero: Nothing or Everything.D. Mountains to Seas: Ups and Downs.
第 1 步判断题型——只看题干，不看原文
怎么做：只凭每题题干里的信号词，凭第一判断圈出题型。这一步不许回原文。
28细节理解推理判断主旨大意段落作用词义猜测
29细节理解推理判断主旨大意段落作用词义猜测
30细节理解推理判断主旨大意段落作用词义猜测
31细节理解推理判断主旨大意段落作用词义猜测
第 2 步找依据句——回原文划句、填段落号
怎么做：从每题题干的信号词出发，回到原文划出该题的依据句，并在句旁标注题号，然后把依据句所在的段落号填在下面。
28→ 第段
29→ 第段
30→ 第段
31→ 第段
需要扫全篇的题（不锚定单独一句），段落号处写「全篇」。
第 3 步长难句攻关
怎么判断：一个句子同时满足三条才值得攻关——句长超过 20 词、结构有两层以上嵌套、和本题相关。把你判断需要攻关的句子抄进下面的框，划出主干（主—谓—宾），圈出连接词。
题号 　原句抄写：
主干（主—谓—宾）：
题号 　原句抄写：
主干（主—谓—宾）：
没有需要攻关的句子就留空——跳过也是判断。
第 4 步正式作答
我的答案 28. 29. 30. 31. （依据句和长难句都过了，再填 A/B/C/D）
