课时分层作业(十)Section Ⅰ(建议用时：30分钟)[高考题型练习提能力]Ⅰ.阅读理解AMother Nature is a cruel mistress.Why? Read on to find the answer.VeniceThis iconic city is sinking rapidly.The canals that make up the streets of Venice rise 2mm every year，making relics of history go under the surface of water and destroying architecture.Experts warn that without intervention (干预)，this city will disappear back into the water at an even faster rate，consumed by rising sea level from melting polar ice caps.Machu PicchuThese Incan ruins have drawn adventurous tourists into the mountains of South America.The forces of natural erosion have been accelerated by tourism and this landmark faces severe influence from increasing foot traffic.The Peruvian government recently suggested a cable car that would cut out the intense hike up to the ruins，making the site instantly accessible to millions，but the future of Machu Picchu remains uncertain.Glacier National ParkPerhaps you've heard that the ice caps are melting.But nowhere is more apparent in the United States than in Glacier National Park.Estimates indicate that the glaciers that are part of the beauty of this national landmark will disappear entirely in the next two decades.The Great Barrier ReefHidden from view beneath the waves，the Great Barrier Reef has been rapidly dying off.Nearly fifty percent of coral which once occupied a large area is gone，destroyed by pollution and disease.【语篇解读】本文是应用文，文章主要介绍了世界上濒临消失的几个旅游胜地。

]BSince the first Earth Day in 1970，Americans have gotten a lot “greener”toward the environment.“We didn't know at that time there even was an environment，let alone that there was a problem with it，”says Bruce Anderson，president of Earth Day USA.But what began as nothing important in public affairs has grown into a social movement.Business people，political leaders，university professors，and especially millions of grassroots Americans are taking part in the movement.“The understanding has increased many，many times，”says Gaylord Nelson，the former governor from Wisconsin，who thought up the first Earth Day.According to US government reports，emissions (排放) from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons.The number of cities producing CO beyond the standard has been reduced from 40 to 9.Although serious problems still remain and need to be dealt with，the world is a safer and healthier place.A kind of “green thinking”has become part of practices.Great improvement has been achieved.In 1988 there were only 600 recycling programs; today in 1995 there are about 6，600.Advanced lights，motors，and building designs have helped save a lot of energy and therefore prevented pollution.Twentyfive years ago，there were hardly any education programs for environment.Today，it's hard to find a public school，university，or law school that does not have such a kind of program.“Until we do that，nothing else will change！”say Bruce Anderson.【语篇解读】在文章中作者介绍了自从1970年第一个地球日成立以来，美国的环境问题有了很大的改善。
