2026年新高考全国I卷-阅读理解C篇

2026年新高考I卷阅读理解C篇

【1】In line with longstanding initiatives to expand its green spaces, New York City is planting tens of thousands of trees each year. They provide shade, lower surface temperatures, absorb a surprising amount of airborne carbon, remove tiny pollutants, and provide wildlife habitat along with just plain beauty.

【2】Something could go wrong, though, according to a new study. Oaks and sweetgums, which currently account for a majority of the city’s trees, produce huge amounts of a chemical substance called isoprene. Harmless by itself, isoprene interacts rapidly with polluting nitrogen oxides released by vehicles, buildings and industry to form ground-level ozone (臭氧)—a major factor in many breathing problems.

【3】The research, carried out by scientists at the Columbia Climate School and other institutions, found that if the city maintains past species patterns in new plantings, isoprene production in Manhattan in coming decades will go up by about 140%, and resulting summer ozone levels as much as 30%.

【4】“We’re all for planting more trees. They bring so many good things,” said study coauthor Róisín Commane. “But if we’re not careful, we could make air quality worse.”

【5】The Parks Department is notoblivious tothe issue. A study carried out by some of its researchers several years ago concluded that city trees did release isoprene. “We didn’t make a big deal of that,” said Novem Auyeung, a Parks Department senior scientist. She said trees should not be viewed as the enemy. “We could plant any trees we want to, if we just rethink our car-centric lifestyle,” she said.

【6】“We’re not going to go cutting down any big old oaks, and neither will the department completely stop planting new ones,” said Auyeung. “You have to think about what you would lose if you do that.” Oaks are keystone species, she pointed out, providing food and habitat for native insects, birds and other animals.

28.What does the new study imply regarding oaks and sweetgums?

A. They affect the growth of other trees.

B. They absorb less carbon than expected.

C. They harm people’s health indirectly.

D. They raise the local temperature slowly.

29.Which of the following may Commane suggest based on their study?

A. Cutting down the isoprene-producing trees.

B. Suspending tree-planting for a few decades.

C. Changing the species of trees in new plantings.

D. Removing isoprene released by existing trees.

30.What does the underline phase “oblivious to” in paragraph 5 mean?

A. Honest about.

B. Unaware of.

C. Related to.

D. Optimistic about.

31.What would Auyeung probably advocate?

A. Reducing car use in daily life.

B. Providing animals with new habitats.

C. Controlling population growth.

D. Doing more research on the problem.

28. C；新研究指出，橡树和枫香树释放的异戊二烯（isoprene）本身无害，但会与车辆、建筑及工业排放的氮氧化物反应，生成地面臭氧（ground-level ozone），而臭氧是"许多呼吸问题的主要因素"。因此，这两种树间接危害人体健康。【定位原文：Oaks and sweetgums... produce huge amounts of a chemical substance called isoprene. Harmless by itself, isoprene interacts rapidly with polluting nitrogen oxides... to form ground-level ozone—a major factor in many breathing problems.刘凯老师解题思路：本题考查推理判断（imply）。解题关键是理清因果链：橡树/枫香树 → 释放异戊二烯（isoprene）

异戊二烯 + 氮氧化物（来自车辆、建筑、工业）→ 地面臭氧（ground-level ozone）

地面臭氧 → 呼吸问题（breathing problems）

这是一个间接危害的过程，而非树木本身直接有毒；

常见错误：误选 B：看到第1段提到吸收碳，但题目问的是第2段新研究的发现，两段信息不可混用。误选 D：将第1段树木"降温"的好处与第2段的问题混淆，或误以为臭氧会导致升温】

29. C；Commane 明确表示 "We're all for planting more trees"（完全支持多种树），但提醒 "if we're not careful, we could make air quality worse"。结合第3段研究结论——"if the city maintains past species patterns in new plantings, isoprene production... will go up by about 140%"——可推断她建议改变新植树木的物种搭配，而非停止种树或砍伐现有树木。【定位原文：...if the city maintains past species patterns in new plantings, isoprene production... will go up by about 140%, and resulting summer ozone levels as much as 30%.；"We're all for planting more trees... But if we're not careful, we could make air quality worse."】【常见错误：误选 A：将第6段 Auyeung 的表态（不会砍伐）误认为是 Commane 的观点，或混淆两人立场。误选 B：看到"air quality worse"就推断要停止种树，忽略了"all for planting more trees"的明确态度】

30. B；"oblivious to" 意为 unaware of（不知道、未意识到）。后文提到 Parks Department 的研究人员数年前就已得出城市树木释放异戊二烯的结论，说明他们并非不知情。【定位原文：The Parks Department is not oblivious to the issue. A study carried out by some of its researchers several years ago concluded that city trees did release isoprene.】

31. A；Auyeung 指出 "We could plant any trees we want to, if we just rethink our car-centric lifestyle"（只要重新思考以汽车为中心的生活方式，我们可以种植任何想种的树）。因此她最可能倡导的是在日常生活中减少汽车使用。【定位原文："We could plant any trees we want to, if we just rethink our car-centric lifestyle," she said.】【常见错误：误选 B：将第6段"橡树为动物提供栖息地"这一事实性描述误认为是 Auyeung 的倡导主张。误选 D：将科学家的身份与研究行为简单挂钩，忽略了文中明确给出的"rethink car-centric lifestyle"这一具体主张。】

【1段】纽约市大规模植树，树木带来多重生态效益

【2段】转折：橡树和枫香树释放异戊二烯，与氮氧化物反应生成地面臭氧，引发呼吸问题

【3段】研究数据：若维持现有物种模式，曼哈顿异戊二烯产量将增140%，夏季臭氧水平增30%

【4段】Commane 观点：支持种树，但需谨慎避免恶化空气质量

【5段】公园部门早已知晓该问题；Auyeung 认为不应将树木视为敌人，应改变"以汽车为中心"的生活方式

【6段】不会砍伐老橡树，橡树是关键物种，为野生动物提供食物和栖息地

文章大意：

纽约市每年大规模植树以扩大绿地，树木能遮阳降温、吸收碳、净化污染物并提供野生动物栖息地。然而，一项新研究指出，该市目前占多数的橡树和枫香树会释放大量异戊二烯（isoprene），这种物质虽本身无害，但会与车辆、建筑及工业排放的氮氧化物反应，生成危害呼吸健康的地面臭氧。研究显示，若新植树仍维持现有物种模式，曼哈顿未来几十年的异戊二烯产量将激增约140%，夏季臭氧水平可能上升30%。

研究者Commane支持继续植树，但提醒需谨慎选种以避免恶化空气质量。公园部门科学家Auyeung则表示，树木并非敌人，问题根源在于"以汽车为中心的生活方式"；只要减少汽车依赖，就可以自由种植任何树种，而不必砍伐作为关键物种、为众多野生动物提供栖息地的老橡树。

词汇拓展：

oblivious /əˈblɪviəs/ adj. 未察觉的，未注意的；健忘的

常见搭配：oblivious of/to sth. 未意识到某事

例句：He was oblivious to the danger. 他没有意识到危险。

文章核心矛盾：树木的生态效益 vs. 特定树种带来的间接空气污染问题。作者并未否定植树，而是强调科学选种与减少汽车污染的重要性。
