Passage 1原文节选（含题干对应段落标记）

〈1〉The debate over climate change has long shifted from “Is it happening?” to “How fast?” and “What will be the consequences?” While natural variability does play a role, overwhelming evidence now confirms that human activities—particularly the emission of greenhouse gases from fossil fuel combustion—are the dominant cause of the rapid warming observed since the mid-20th century.

〈2〉Ice cores from Antarctica and Greenland, tree-ring records, and satellite observations all point to a warming trend unprecedented in at least the past 1,000 years. Glaciers are retreating globally, sea levels are rising at twice the rate of the 20th century average, and extreme weather events—such as heatwaves, droughts, and intense storms—are increasing in frequency and severity.

〈3〉Skeptics often cite the medieval warm period or the little ice age as proof that current changes are natural. Yet these historical fluctuations occurred regionally and lacked the global synchrony and magnitude of today’s warming. Climate models that incorporate only natural forcings (e.g., solar activity, volcanic eruptions) fail to reproduce the observed warming since 1970; only when anthropogenic greenhouse gases are included do simulations match reality.

〈4〉This places a moral and practical imperative on humanity: to mitigate future risks, we must drastically reduce emissions. The principle of “common but differentiated responsibilities” recognizes that developed nations, having contributed most to historical emissions, bear greater responsibility for mitigation and must provide financial and technological support to developing countries.

〈5〉Without urgent, coordinated action, the world faces cascading impacts—displacement of coastal populations, collapse of ecosystems like coral reefs, and food system disruptions—that could destabilize societies and economies.

① Main Idea Question（主旨题）

Which of the following best expresses the main idea of the passage?

A) Climate change is primarily caused by natural factors over geological time scales.

B) Human activities are the principal driver of recent global warming, demanding urgent global cooperation.

C) The economic costs of climate action outweigh the benefits of mitigation.

D) Developing countries should bear the same emission reduction obligations as industrialized nations.

答案：B

解析：本题考查对全文核心论点的把握。A项错误在于“natural factors”与原文“dominant cause”矛盾；C项未在文中出现；D项曲解“differentiated responsibilities”原则。B项准确概括了“人类活动主导+需协同应对”的双重主旨。

② Vocabulary in Context（词义题）

In Paragraph 1, the word “dominant” is closest in meaning to ______.

A) temporary

B) occasional

C) prevailing

D) marginal

答案：C

解析：“dominant cause”意为“主导性原因”，与“prevailing”（普遍存在的、占主导地位的）同义。A、B、D均为贬义或弱化词，与语境不符。

③ Detail Question（细节题）

According to Paragraph 2, which of the following is NOT mentioned as evidence of climate change?

A) Retreat of glaciers worldwide

B) Rising sea levels

C) Increased frequency of earthquakes

D) More frequent extreme weather events

答案：C

解析：〈2〉段明确提到A、B、D三项；地震（earthquakes）属地质活动，未被列为气候变化证据，属典型“无中生有”干扰项。

④ Inference Question（推理题）

It can be inferred from Paragraph 3 that climate models that ignore human influences ______.

A) accurately simulate past climate patterns

B) overestimate the role of solar activity

C) fail to reproduce recent warming trends

D) are more reliable than observational data

答案：C

解析：〈3〉段末句明确指出“only when anthropogenic greenhouse gases are included do simulations match reality”，反推即为C项。A项与事实相反；B、D项无依据。

⑤ Attitude Question（态度题）

The author’s attitude toward “skeptics” is best described as ______.

A) sympathetic

B) dismissive

C) neutral

D) admiring

答案：B

解析：作者用“Yet these historical fluctuations occurred regionally…”“fail to reproduce”等表述，表明对质疑者论点的否定与轻视，“dismissive”（轻蔑的）最贴切。非“neutral”（中立）或“sympathetic”（同情）。

【重点句式拆解】

“The ‘black box’ nature of deep learning algorithms makes it difficult to trace how a particular decision was reached, raising concerns about accountability.”

→ 主干：The nature… makes it difficult to trace…；其中it为形式宾语，真正宾语为to trace…；分词短语raising…作结果状语。

翻译：深度学习算法的“黑箱”特性，使得追溯某一具体决策的生成路径变得困难，从而引发了对责任归属问题的担忧。

“While AI can process vast amounts of data more efficiently than humans, it lacks the contextual awareness and moral reasoning that underpin sound judgment.”

→ 让步状语从句+主句；that引导定语从句修饰awareness and reasoning。

翻译：尽管人工智能处理海量数据的效率远超人类，但它缺乏支撑审慎判断所必需的情境感知与道德推理能力。

【逻辑连接词识别】

• While…, it…（让步转折）
• However, …（强转折）
• Moreover, …（递进）
• Specifically, …（举例说明）
• Therefore, …（因果结论）

① Vocabulary in Context（词义题）

In Paragraph 1, the word “underscore” most nearly means ______.

A) emphasize

B) overlook

C) complicate

D) complicate

答案：A

解析：“underscore the need for…”意为“凸显/强调……的必要性”，与“emphasize”同义。B项“overlook”意为忽视，C、D项重复（应为complicate），均不符。

② Detail Question（细节题）

According to the passage, which of the following is a specific example of algorithmic bias?

A) AI systems using too much computational power

B) Facial recognition software performing less accurately on darker-skinned individuals

C) Doctors relying too heavily on AI diagnostics

D) Data breaches exposing patient records

答案：B

解析：文中以“facial recognition”为例说明训练数据偏倚导致的种族/肤色歧视问题，是典型偏见案例。A项属效率问题，非偏见；C、D项属责任与安全问题，非偏见本身。

③ Inference Question（推理题）

It can be inferred that the author would most likely support ______.

A) unrestricted deployment of AI in critical sectors

B) replacing human decision-makers with AI in legal judgments

C) embedding ethical considerations into AI design from the outset

D) delaying AI implementation until all technical issues are resolved

答案：C

解析：末段明确主张“value-sensitive design”与“human-in-the-loop”，即在设计初期即嵌入伦理考量，并保留人类监督权。A、B项与作者立场相悖；D项“delaying”非文中所倡，作者主张“负责任推进”而非停滞。

④ Main Idea Question（主旨题）

The passage is primarily concerned with ______.

A) advocating for a ban on AI in sensitive domains

B) examining the benefits and risks of AI applications

C) criticizing corporate misuse of personal data

D) promoting a specific regulatory framework

答案：B

解析：全文结构为“利—弊—应对”，核心是平衡视角。A项“ban”过于极端；C项仅涉及隐私问题，以偏概全；D项“specific framework”未具体命名，属过度推断。

● algorithmic bias（算法偏见）

结构：algorithm（算法）+ -ic（形容词后缀）+ bias（偏见）→ 指因训练数据偏差导致的系统性歧视；

现实案例：某面部识别系统对深肤色人群识别率低达34%，对浅肤色仅0.8%；

考研高频：2018-2023年连续6年出现“bias”相关考题，属科技伦理高频词；

解题提示：遇到“bias”，优先考虑“unfair treatment”“discrimination”等选项。

● ethical dilemma（伦理困境）

搭配：face/encounter an ethical dilemma；

近义表达：moral quandary, principled conflict；

反义词：clear-cut case（非黑即白的情形）；

考研真题链接：2020年Text 3提及“AI in hiring”引发ethical dilemma。

● whereas / while（对比连词）

用法：连接两个对比事实，主句主语需不同；

真题例句：“AI can process data rapidly, whereas humans require more time for analysis”；

易错点：不可省略主语，如错误：“…whereas rapid”→ 应为“…whereas humans process it rapidly”；

考研统计：2004-2023年出现27次，是阅读理解最高频对比连词。

● hence / therefore（因果连接词）

位置：句首用逗号隔开，句中用分号+逗号；

真题例句：“Temperatures have risen sharply; hence, policy changes are urgent”；

同义替换：consequently, as a result；

干扰项特征：题干问“reason”，选项含“hence”可能为正确答案。
