篇章概要

本文选自《The Guardian》与联合国环境规划署联合报道风格，系统论述全球气候危机的成因、表现与应对路径。文章采用“问题—影响—对策”三段式结构：首段以极端天气事件切入，引出温室气体累积的科学事实；中段详述冰川消融、海平面上升、生物多样性锐减等生态连锁反应；末段强调《巴黎协定》框架下的多边合作机制，并指出碳中和目标的实现路径——包括能源结构转型、绿色技术创新与公众行为变革。

题目解析

• ①

  题目：What is the main purpose of the passage?

  答案：To emphasize the urgency of addressing climate change and call for collective action.

  解析：主旨题需把握全文基调。文章未止步于现象罗列，而是通过“alarming”“irreversible”“imperative”等词层层推进，最终落脚于“urgency”与“action”。干扰项如“describe weather patterns”仅覆盖细节，未触及作者意图。

• ②

  题目：Which of the following is NOT mentioned as a greenhouse gas?

  答案：Ozone (O₃)

  解析：细节题需定位关键词。文中明确列出CO₂（二氧化碳）、CH₄（甲烷）、N₂O（一氧化二氮）及氟化气体（F-gases），但未提及臭氧——其虽属大气成分，但在本语境中主要作为平流层紫外线防护层，非人为温室效应主因。

• ③

  题目：According to the passage, what is the key to effective climate policy?

  答案：International cooperation and binding commitments.

  解析：推理题需结合段落逻辑。第三段指出“unilateral efforts remain fragmented”，继而强调“the Paris Agreement’s strength lies in its universality and bottom-up contribution”，揭示多边主义与法律约束力的双重必要性。

• ④

  题目：The tone of the passage can best be described as ______.

  答案：Urgent yet hopeful

  解析：态度题需识别情感倾向词。“alarming”“threatening”体现紧迫感，“innovation”“resilience”“opportunity”传递希望，属辩证型结论。

• ①

  原句：Traditional education, ______ centered on the teacher, often prioritizes knowledge transmission over critical thinking.

  选项：A. primarily B. temporarily C. reluctantly D. occasionally

  答案：A. primarily

  解析：“centered on the teacher”为固定搭配“以教师为中心”，需副词修饰“centered”。primary意为“主要地”，与后文“over critical thinking”构成对比逻辑。其他选项（暂时地/不情愿地/偶然地）均不符合教育理论语境。

• ②

  原句：New models emphasize personalized learning, ______ enables students to progress at their own pace.

  选项：A. what B. which C. where D. that

  答案：B. which

  解析：非限制性定语从句，先行词为整个前句内容，用which引导。that不可用于非限制性从句；what无指代功能；where表地点，此处不适用。

• ③

  原句：A major ______ lies in the uneven distribution of qualified teachers across regions.

  选项：A. obstacle B. opportunity C. outcome D. origin

  答案：A. obstacle

  解析：前文谈“挑战”，后文“uneven distribution”为负面因素，obstacle（障碍）最契合。opportunity（机会）逻辑矛盾；outcome（结果）语义不符；origin（起源）需与“the cause of”搭配。

Dear fellow students,

With plastic waste choking our oceans and landfills, the time to act is now. Every year, 8 million tons of plastic enter marine ecosystems, harming wildlife and entering our food chain. As future leaders, we must lead by example.

Here’s how you can help:

1. Bring reusable bottles and containers to campus;
2. Decline plastic bags at cafeterias;
3. Join the “Zero-Waste Week” event on April 22 (Earth Day).

Small choices create big change. Let’s build a greener campus—together.

Sincerely,
Li Hua
Student Union President

The rapid advancement of artificial intelligence has transformed how we live, work, and learn. While AI enhances efficiency in healthcare and transportation, it also raises profound ethical questions: Who decides algorithmic priorities? How do we protect privacy in a data-driven world?

Technology without humanity is dangerous. As the ancient Chinese philosopher Confucius warned, “The superior man is concerned with righteousness; the inferior man is concerned with profit.” We must embed ethics into every line of code. Universities should offer interdisciplinary courses—blending AI with philosophy, law, and sociology—to cultivate technologists who prioritize human dignity.

In conclusion, innovation must serve humanity, not replace it. Let’s build a future where machines augment human potential, not diminish our values.
