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.词义指代题.根据第二段"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"傅里叶得出结论,大气必须负责吸收太阳吸收的热量,并将其描述为一个有玻璃盖的盒子:当光线穿过玻璃时,由于盖住了热量,盒子内部变得更热.可知 "it"指的是"大气".故选C. 2.细节理解题.根据最后一段" 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世纪50年代末,美国科学家一直在对气候变化的长期后果发出*告.自从傅里叶第一次描述了温室效应以来,气候变化研究已经取得了长足的进步".可知科学家是到20世纪50年代发现全球变暖的负面影响的*据的.故选C. 3.推理判断题.根据最后一段"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.自从傅里叶第一次描述了温室效应以来,气候变化研究已经取得了长足的进步--尽管如此,也许阿伦尼乌斯应该更加小心他所希望的."可知作者对阿伦尼乌斯的愿望是反对的.故选B. 4.主旨大意题.根据第一段"But the concept itself isn't new at all --- in fact, scientists have been exploring questions about climate change for almost 200 years.但这一概念本身并不新鲜--事实上,科学家们研究气候变化问题已经有近200年的历史了."可知文章主要介绍了气候变化探索.故选D.
