Lakes, Too, Feel Global Warming

There’s no doubt: In the last few decades, the average temperature on Earth has been higher than it’s been in hundreds of years. Around the world, people are starting to measure the effects of global warming — and trying to figure out what to do about it.

Scientists recently used satellites to study the temperatures of lakes around the world, and they found that lakes are heating up.Between 1985 and 2009,satellites recordedthe nighttime temperatures of the surfaces of 167 lakes. During those 24 years, the lakes got warmer　—　by an average of about 0.045 degree Celsius per year.

In some places, lakes have been warming by as much as 0.10 degree Celsius per year. At that rate, a lake may warm by a full degree Celsius, or 1.8 degrees Fahrenheit, in just 10 years. That difference may seem small — you might not even notice it in your bathtub. But in a lake, slightly warmer temperatures could mean more algae, and algae can make the lake poisonous to fish.

The scientists who did the study work for NASA’s Jet Propulsion Laboratory at the California Institute of TechnologyinPasadena.Theyreportthatlakesseem to bewarming faster in the northern parts of the Northern Hemisphere. In the United States, lakes in the southwestern part of the country warmed faster than did the Great Lakes in the north.

The study shows that in some regions, lakes are warming faster than the air around them. This is important because scientists often use measurements of air temperature to study how the Earth is warming. By using lake temperatures as well, scientists can get a better picture of global warming.

The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.

That’s going to be useful, since no country is too big or too small to ignore climate change.

Scientists aren’t the only ones concerned. Everyone who lives on Earth is going to be affected by therapidwarming of the planet.Many world leaders believe we might be able to do something about it, especially by reducing the amount of greenhouse gases we put into the air.

That’s why the United Nations started the Framework Convention on Climate Change, or UNFCCC. Every year the convention meets, and representatives from

countries around the world gather to talk about climate change and discuss global solutions to the challenges of a warming world.

16.Scientist have been keeping records of lake temperatures for over 30 years.

A) Right

16 B 文中第二段提到科學(xué)家在 1985 到 2009年的24年間不斷地測量湖泊的夜間溫度。然而，題干認(rèn)為科學(xué)家對湖泊溫度的測量超過 30 年，與文章本意不符。

17 B 文中第二段最后兩句話提到科學(xué)家連續(xù) 24年測量了世界上 167個湖泊的夜間溫度。測量的結(jié)果是這些湖泊的溫度每年增長 0.045 度。題干中認(rèn)為的"世界的湖泊溫度大幅增 長"的表達不符合文章本意。

18 C 文章第三段第一句話只提到了有些地方湖泊的溫度增長可以每年達到O. 1 攝氏度，但并沒有說是亞洲湖泊，因此本題的答案應(yīng)是選項 C，"沒有提及"。

19 A 文章第三段最后一句話提到"一個湖泊水溫的輕微升高都會導(dǎo)致水藻增多，并且水藻使得湖泊有毒而不適合魚類生存"，因此本文題干表達的意思符合文章本意，選擇答案A。

20 A 文章第四段第二句話提到"科學(xué)家經(jīng)常使用對空氣溫度的測量值來研究地球變暖的情況"，因此題干表達的意思與文章本意相符。答案為 A。

21 B 文章第五段第一句話提到"世界上沒有哪個國家會很大或很小以至于不用關(guān)注氣候的變化"，因此，題干中提到的"一些小國家受到氣候變暖的威脅比較小"與文章本意不符。答案為B。

22 C 文章最后一段提到了"聯(lián)合國氣候變化框架公約"的年會，但是沒有提到今年的會議在墨西哥舉行，所以題干中提到的信息在文中沒有顯示。答案為 C。
