27.What can we conclude from the passage?A.Love breaks down barriers.B.Education promises a bright future.C.Great hopes make great man.D.Two heads are better than one.CResearchers estimate that roughly one-third of Earth's lakes are blue.But,should aver-age summer air temperatures rise by a few degrees,some of those crystal waters could turn amurky green or brown,the team reports in the Sept.28 Geophysical Research Letters.Lake color depends in part on what's in the water,but factors such as water depth andsurrounding land use also matter.Compared with blue lakes,green or brown lakes have morealgae(藻类)，sediment(沉淀)and organic matter..Yang,a hydrologist at Southern Method-ist University in Dallas,and colleagues used satellite photos from 2013 to 2020 to analyze thecolor of more than 85,000 lakes around the world.The scientists then looked at local climatesduring that time to see how they may be linked to lake color around the world.Lakes in places with average summer air temperatures that were below 19Celsius weremore likely to be blue than lakes with warmer summers,the researchers found.If averagesummer temperatures increase another 3 degrees Celsius-an amount that scientists think isprobable by the end of the century-those 3,800 lakes could turn green or brown.That's be-cause warmer water helps algae bloom more,which changes the properties of the water,giv-ing it a green-brown.Lakes are often used for drinking water,food or recreation.If the water is more blockedwith algae,it could be unappealing for play or more costly to clean for drinking.But the colorchanges wouldn't necessarily mean that the lakes are any less healthy."Humans don't valuelots of algae in a lake,but if you're a certain type of fish species,you might be like 'this isgreat',"O'Reilly says.Lake color can hint at the stability of a lake's ecosystem,with shifting shades indicatingchanging conditions for the creatures living in the water.One benefit of the new study is thatit gives scientists a baseline for assessing how climate change is affecting Earth's freshwaterresources.Continued monitoring of lakes could help scientists detect future changes.28.What are the first two paragraphs mainly about?A.The reasons for global warming.B.The causes of the changes in lake colourC.The stability of a lake's ecosystem.D.The efforts to fuel the growth of algae.29.What can we learn about algae from the passage?A.Algae have been used to control global climateB.Algae play a declining role in the lake color.C.Lakes with more algae may appear greener.D.More algae make the lake less healthy.
