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 一 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 recorded the 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 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 (有毒的）to fish. The study shows that in some regions,they are warming faster than the air around them. This is important because scientis ofen 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 apund 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 the rapid warming of the planet. Many world leaders believe we might be able to do something about it, especially ^reducing the amount of greenhouse (温室）gases we put into the air. That’s why the United Nations sntad the Frammork Convention on Climate Change, or UNFCCC. Every year the convention meets, and presentatives from countries around the world gather to talk about climate change and discuss global solutions to the challenges of a warming world. Global warming is less threatening to small countries.

选项 A Right B Wrong C Not mentioned

答案 B

解析文章第五段第一句话提到“世界上没有哪个国家会因为很大或很小而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。
