2026年新高考I卷閱讀理解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，橡樹和楓香樹釋放的異戊二烯（isoprene）本身無害，但會與車輛、建筑及工業(yè)排放的氮氧化物反應，生成地面臭氧（ground-level ozone），而臭氧是"許多呼吸問題的主要因素"。因此，這兩種樹間接危害人體健康。【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.劉凱老師解題思路：本題考查推理判斷（imply）。解題關鍵是理清因果鏈：橡樹/楓香樹 → 釋放異戊二烯（isoprene）

異戊二烯 + 氮氧化物（來自車輛、建筑、工業(yè)）→ 地面臭氧（ground-level ozone）

地面臭氧 → 呼吸問題（breathing problems）

這是一個間接危害的過程，而非樹木本身直接有毒；

常見錯誤：誤選 B：看到第1段提到吸收碳，但題目問的是第2段新研究的發(fā)現，兩段信息不可混用。誤選 D：將第1段樹木"降溫"的好處與第2段的問題混淆，或誤以為臭氧會導致升溫】

29. C；Commane 明確表示 "We're all for planting more trees"（完全支持多種樹），但提醒 "if we're not careful, we could make air quality worse"。結合第3段研究結論——"if the city maintains past species patterns in new plantings, isoprene production... will go up by about 140%"——可推斷她建議改變新植樹木的物種搭配，而非停止種樹或砍伐現有樹木。【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."】【常見錯誤：誤選 A：將第6段 Auyeung 的表態(tài)（不會砍伐）誤認為是 Commane 的觀點，或混淆兩人立場。誤選 B：看到"air quality worse"就推斷要停止種樹，忽略了"all for planting more trees"的明確態(tài)度】

30. B；"oblivious to" 意為 unaware of（不知道、未意識到）。后文提到 Parks Department 的研究人員數年前就已得出城市樹木釋放異戊二烯的結論，說明他們并非不知情。【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"（只要重新思考以汽車為中心的生活方式，我們可以種植任何想種的樹）。因此她最可能倡導的是在日常生活中減少汽車使用。【定位原文："We could plant any trees we want to, if we just rethink our car-centric lifestyle," she said.】【常見錯誤：誤選 B：將第6段"橡樹為動物提供棲息地"這一事實性描述誤認為是 Auyeung 的倡導主張。誤選 D：將科學家的身份與研究行為簡單掛鉤，忽略了文中明確給出的"rethink car-centric lifestyle"這一具體主張。】

【1段】紐約市大規(guī)模植樹，樹木帶來多重生態(tài)效益

【2段】轉折：橡樹和楓香樹釋放異戊二烯，與氮氧化物反應生成地面臭氧，引發(fā)呼吸問題

【3段】研究數據：若維持現有物種模式，曼哈頓異戊二烯產量將增140%，夏季臭氧水平增30%

【4段】Commane 觀點：支持種樹，但需謹慎避免惡化空氣質量

【5段】公園部門早已知曉該問題；Auyeung 認為不應將樹木視為敵人，應改變"以汽車為中心"的生活方式

【6段】不會砍伐老橡樹，橡樹是關鍵物種，為野生動物提供食物和棲息地

文章大意：

紐約市每年大規(guī)模植樹以擴大綠地，樹木能遮陽降溫、吸收碳、凈化污染物并提供野生動物棲息地。然而，一項新研究指出，該市目前占多數的橡樹和楓香樹會釋放大量異戊二烯（isoprene），這種物質雖本身無害，但會與車輛、建筑及工業(yè)排放的氮氧化物反應，生成危害呼吸健康的地面臭氧。研究顯示，若新植樹仍維持現有物種模式，曼哈頓未來幾十年的異戊二烯產量將激增約140%，夏季臭氧水平可能上升30%。

研究者Commane支持繼續(xù)植樹，但提醒需謹慎選種以避免惡化空氣質量。公園部門科學家Auyeung則表示，樹木并非敵人，問題根源在于"以汽車為中心的生活方式"；只要減少汽車依賴，就可以自由種植任何樹種，而不必砍伐作為關鍵物種、為眾多野生動物提供棲息地的老橡樹。

詞匯拓展：

oblivious /??bl?vi?s/ adj. 未察覺的，未注意的；健忘的

常見搭配：oblivious of/to sth. 未意識到某事

例句：He was oblivious to the danger. 他沒有意識到危險。

文章核心矛盾：樹木的生態(tài)效益 vs. 特定樹種帶來的間接空氣污染問題。作者并未否定植樹，而是強調科學選種與減少汽車污染的重要性。
