问题                 Lakes, Too, Feel Global Warming
    There’s no doubt, In the last few decades, the average temperature on Earth has been higher than it has 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.     Scientist 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 recorded the night time 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 in just 10 years. That difference may seem small, you might not even notice it in your bath. But in a lake, slightly warmer temperatures could mean more algae(水藻) and algae can make the lake poisonous to fish.
    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 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 matter the country is too big or too small, can’t ignore climate changes. Scientists aren’t the only ones concerned. Everyone who lives on Earth is going to be affected by the rapid warming of the planet. Many world leaders believe we might be able to do something about it, especially by reducing the amount of greenhouse (温室)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.
A slight temperature increase in a lake could be harmful for fish.

选项 A、Right
B、Wrong
C、Not mentioned

答案A

解析 本题难度不大,答案依据比较明显,在文章第三段最后一句:But in a lake,slightly warmer temperatures could mean more algae(水藻),and algae can make the lake poisonous to fish.谈到湖水温度上升会产生很多水藻,给湖里的鱼类带来毒害,题干和原文句意相符,答案是A。
