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

B) Wrong

C) Not mentioned

17.The temperatures of lakes around the world have increased greatly between 1985 and 2009.

B) Wrong

C) Not mentioned

19. A slight temperature increase in a lake could be harmful to fish.

A) Right

B) Wrong

C) Not mentioned

20. Scientists generally focus on air temperatures when studying global warming.

22. UNFCCC’s annual meeting will be held in Mexico this year.

A) Right

16 B 文中第二段提到科学家在 1985 到 2009年的24年间不断地测量湖泊的夜间温度。然而，题干认为科学家对湖泊温度的测量超过 30 年，与文章本意不符。

17 B 文中第二段最后两句话提到科学家连续 24年测量了世界上 167个湖泊的夜间温度。测量的结果是这些湖泊的温度每年增长 0.045 度。题干中认为的"世界的湖泊温度大幅增 长"的表达不符合文章本意。

18 C 文章第三段第一句话只提到了有些地方湖泊的温度增长可以每年达到O. 1 摄氏度，但并没有说是亚洲湖泊，因此本题的答案应是选项 C，"没有提及"。

19 A 文章第三段最后一句话提到"一个湖泊水温的轻微升高都会导致水藻增多，并且水藻使得湖泊有毒而不适合鱼类生存"，因此本文题干表达的意思符合文章本意，选择答案A。

20 A 文章第四段第二句话提到"科学家经常使用对空气温度的测量值来研究地球变暖的情况"，因此题干表达的意思与文章本意相符。答案为 A。

21 B 文章第五段第一句话提到"世界上没有哪个国家会很大或很小以至于不用关注气候的变化"，因此，题干中提到的"一些小国家受到气候变暖的威胁比较小"与文章本意不符。答案为B。

22 C 文章最后一段提到了"联合国气候变化框架公约"的年会，但是没有提到今年的会议在墨西哥举行，所以题干中提到的信息在文中没有显示。答案为 C。
