问题 共用题干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 sur-
faces 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一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 impor-
tant 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 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 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.
选项 Scientists have been keeping records of lake temperatures for over 30 years.A:RightB:WrongC:Not mentioned
答案B
解析由第二段可知，科学家从1985年开始记录湖水温度的，到现在还不到30年。 由第二段最后一句话可知，此判断正确。 湖水在亚洲温暖的快在文中没有信息依据。 由第三段最后一句话可知，此判断正确。 由第四段第二句话可知，科学家经常用空气温度来研究地球变暖的问题，说明他们关 注的主要焦点在于空气温度。 由第五段的内容可知，地球上的任何人都应关心全球变暖的问题。 在文中没有提及今年的UNFCCC在哪举行。第3部分：概括大意与完成句子
