問題詳情：

Sometimes we may find that every week there are a lot of new stories about how climate change is affecting the planet, or new plans to battle its effects. But the concept itself isn’t new at all — in fact, scientists have been exploring questions about climate change for almost 200 years.

The idea of “greenhouse gases” goes back to 1824, when Joseph Fourier wondered what was regulating the earth’s temperature. Fourier concluded that the atmosphere must be responsible for containing the heat absorbed from the sun and described it as a box with a glass lid: As light shines through the glass, the inside gets warmer as the lid traps the heat. As Fourier’s ideas spread, it came to be called “the greenhouse effect”.

Scientists continued to study the greenhouse effect. Not until a Swedish chemist named Svante Arrhenius came along, did scientists understand how global warming actually works. After years of work, Arrhenius determined that the level of carbon dioxide in the atmosphere did in fact have a direct effect on global temperatures.

Arrhenius found that CO2, and other gases trap radiation, which warms the atmosphere. Arrhenius was the first to suspect that burning coal could contribute to the greenhouse effect. But Arrhenius welcomed the warming effect on the planet. At a lecture later that year, Arrhenius noted that creatures of a warmer earth “might live under a milder sky and in less barren surroundings”.

While Arrhenius’ findings won him the 1903 Nobel Prize in chemistry, scientists kept debating whether the greenhouse effect was increasing until 1950, when researchers finally began to find strong data supporting it. By the end of the 1950s, American scientists had been sounding the alarm on the long-term consequences of climate change. Climate change research has come a long way since Fourier first described the greenhouse effect — still, maybe Arrhenius should have been more careful of what he wished for.

1824.                   1903.                    1950.                   D.200 years ago.

’s the author’s attitude towards Arrhenius’ wish?

mistic.               tive.                  ral.                    guous.

’s the main idea of the text?

es of climate change.                             cts of greenhouse gases.

ings about global warming.                     orations on climate change.

【回答】

1.C; 2.C; 3.B; 4.D 解析：1.詞義指代題.根據第二段"Fourier concluded that the atmosphere must be responsible for containing the heat absorbed from the sun and described it as a box with a glass lid: As light shines through the glass, the inside gets warmer as the lid traps the heat"傅里葉得出結論,大氣必須負責吸收太陽吸收的熱量,並將其描述為一個有玻璃蓋的盒子:當光線穿過玻璃時,由於蓋住了熱量,盒子內部變得更熱.可知 "it"指的是"大氣".故選C. 2.細節理解題.根據最後一段" By the end of the 1950s, American scientists had been sounding the alarm on the long-term consequences of climate change. Climate change research has come a long way since Fourier first described the greenhouse effect - still.到20世紀50年代末,美國科學家一直在對氣候變化的長期後果發出*告.自從傅里葉第一次描述了温室效應以來,氣候變化研究已經取得了長足的進步".可知科學家是到20世紀50年代發現全球變暖的負面影響的*據的.故選C. 3.推理判斷題.根據最後一段"Climate change research has come a long way since Fourier first described the greenhouse effect - still, maybe Arrhenius should have been more careful of what he wished for.自從傅里葉第一次描述了温室效應以來,氣候變化研究已經取得了長足的進步--儘管如此,也許阿倫尼烏斯應該更加小心他所希望的."可知作者對阿倫尼烏斯的願望是反對的.故選B. 4.主旨大意題.根據第一段"But the concept itself isn't new at all --- in fact, scientists have been exploring questions about climate change for almost 200 years.但這一概念本身並不新鮮--事實上,科學家們研究氣候變化問題已經有近200年的歷史了."可知文章主要介紹了氣候變化探索.故選D.
