Lakes,Too,Feel Global WarmingThere'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 degreeCelsius 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 theamount 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.Scientists have been keeping records of lake temperatures for over 30 years.A:RightB:WrongC:Not mentioned

Washoe Learned American Sign Language1.An animal that influenced scientific thought has died.A chimpanzee named Washoe and born in Africa died of natural causes late last month at the age of 42 at a research center in the American state of Washington.Washoe had become known in the scientific community arid around the world for her ability to use American sign language.She was said to be the first non-human to learn a human language.Her skills also led to debate about primates and their ability to understand language.2.Research scientists Allen and Beatrix Gardner began teaching Washoe sign language in 1966.In 1969,the Gardners described Washoe's progress in a scientific report.The people who experimented with Washoe said she grew to understand about 250 words.For example,Washoe made signs to communicate when it was time to eat. She could request foods like apples and bananas.She also asked questions like,"Who is coming to play?"Once the news about Washoe spread,many language scientists began studies of their own into this new and exciting area of research.The whole direction of primate research changed.3. However,critics argued Washoe only learned to repeat sign language movements from watching her teachers.They said she had never developed true language skills.Even now there are some researchers who suggest that primates learn sign language only by memory,and perform the signs only for prizes.Yet Washoe's keepers disagree.Roger Fouts is a former student of the Gardners.He took Washoe to a research center in Ellensburg,Washington.There,Washoe taught sign language to three younger chimpanzees,which are still alive.4.Scientists like private researcher Jane Goodall believe Washoe provided new information about the mental workings of chimpanzees.Today,there are not as many scientists studying language skills with chimps.Part of the reason is that this kind of research takes a very long time.5.Debate continues about chimps' understanding of human communication.Yet,one thing is sure一Washoe changed popular ideas about the possibilities of animal intelligence.Paragraph 2________A:Reason Why Not Many Scientists Carry out This Research Nowadays.B:Report about Washoe's Progress in Learning Sign Language.C:General Information about Washoe.D:The Gardeners' Contributions Recognized.E:Debate on Chimps' Intelligence.F: Washoe's Love for Three Young Chimps.
