energy savings to be made from all recyclable materials，sometimes huge savings.Recycling plastics and aluminum，for instance，uses only 5% to 10% as much energy as producing new plastic or smelting (提炼) aluminum.Long before most of us even noticed what we now call “the environment”， Buckminster Fuller said，“Pollution is nothing but the resources(资源) we are not harvesting We allow them to be left around because we've been ignorant of their value.” To take one example，let's compare the throwaway economy(经济) with a recycling economy as we feed a cat for life.Say your cat weigh 5kg and eats one can of food each day.Each empty can of its food weighs 40g.In a throwaway economy，you would throw away 5，475 cans over the cat's 15­year lifetime.That's 219kg of steel—more than a fifth of a ton and more than 40 times the cat's weight.In a recycling economy，we would make one set of 100 cans to start with，then replace them over and over again with recycled cans.Since almost 3% of the metal is lost during reprocessing，we'd have to make an extra 10 cans each year.But in all，only 150 cans will be used up over the cat's lifetime—and we'll still have 100 left over for the next cat.★What is the author's purpose in writing the text?A．To promote the idea of recycling.B．To introduce an environmentalist.C．To discuss the causes of pollution.D．To defend the throwaway economy.★试题特点目的意图题要求考生根据文章的论述，揣测作者的写作意图及作者运用某种写作手法的目的。作者一般不直接表明自己的意图，而是通过文章所提供的事实，客观地使读者信服某种想法或观点。题干中常有purpose，in order to等词。★解题思路Step 1：定位——体现文章目的意图的信息句(□中句)。Step 2：详读——回收利用可大大节约资源，并引用伟大建筑师富勒的话和给猫喂食的例子说明循环经济的价值所在。Step 3：尝试解答——本文用数字对比了循环经济和一次性经济消耗资源的不同结果，故写作目的是推广回收利用的价值理念。故选A。★名师点津巧用文体解题记叙文一般会在首段或尾段出现高度概括的总结性的语言，且往往有一定的哲理性，所有的叙述都是围绕该哲理展开。应用文文章中有对某种物品或服务的详细介绍，使用具有明显支持倾向的语言。说明文写作目的有赖于对文章主旨的把握，阅读时需要找准主题句。议论文提出论点——进行论证——得出结论，作者的意图往往隐含于最后一部分中。[即学即练]AReading can be a social activity.Think of the people who belong to book groups.They choose books to read and then meet to discuss them.Now，the website BookCrossing.com turns the page on the traditional idea of a book group.Members go on the site and register the books they own and would like to share.BookCrossing provides an identification number to stick inside the book.Then the person leaves it in a public place，hoping that the book will have an adventure，travelling far and wide with each new reader who finds it.★Why does the author mention book groups in the first paragraph?A．To explain what they are.B．To introduce BookCrossing.C．To stress the importance of reading. D．To encourage readers to share their ideas.B　[作者在第一段中提出读书也是一种社交活动，那些参加读书小组的人经常在一起阅读讨论所读内容，增强相互之间的理解。接着在最后一句提出BookCrossing.com，说明作者提到读书小组的目的正是为了介绍BookCrossing.com这个网站。故B项正确。]BSince 1962，Pacific Science Center has been inspiring a passion(热情) for discovery and lifelong learning in science，math and technology.Today，Pacific Science Center serves more than 1.3 million people a year and brings inquiry based science education to classrooms and community events all over Washington State.It is an amazing accomplishment and one we cannot achieve without generous support from individuals，corporations，and other social organizations.Visit pacificsciencecenter.org to find various ways you can support Pacific Science Center.★What is the purpose of the paragraph?A．To encourage donations.B．To advertise coming events.C．To introduce special exhibits.D．To tell about the center's history.A　[本段倒数第二句提及：要是没有个人、大公司和其他社会组织的慷慨支持的话，我们不能实现这样惊人的成就。最后一句呼吁人们寻找各种各样的方式来支持太平洋科学中心。此处可利用排除法解题，本段并没有为该中心做广告，故B项的陈述错误；本段没有介绍特色展品，可排除C项；本段提到这个中心创办于1962年，但是没有介绍它的历史，可排除D项。只有A项提及的鼓励捐赠与本段主旨吻合。故A项正确。]
