题目内容
13.Scientists today are making greater effort to study ocean currents (洋流).Most do it using satellites and other high-tech equipment.However,ocean expert Curtis Ebbesmeyer does it in a special way--by studying movements of floating garbage.A scientist with many years'experience,he started this type of research in the early 1990s when he heard about hundreds of athletic shoes washing up on the shores of the northwest coast of the United States.There were so many shoes that people were setting up swap meets to try and match left and right shoes to sell or wear.
Ebbesmeyer found out in his researches that the shoes-about 60,000 in total-fell into the ocean in a shipping accident.He phoned the shoe company and asked if they wanted the shoes back.As expected,the company told him that they didn't.Ebbesmeyer realized this could be a great experiment.If he learned when and where the shoes went into the water and tracked where they landed,he could learn a lot about the patterns of ocean currents.
The Pacific Northwest is one of the world's best areas for beachcombing(海滩搜寻) because winds and currents join here,and as a result,there is a group of serious beachcombers in the area.Ebbesmeyer got to know a lot of them and asked for their help in collecting information about where the shoes landed.In a year he collected reliable information on 1,600 shoes.With this data,he and a colleague were able to test and improve a computer program designed to model ocean currents,and publish the findings of their study.
As the result of his work,Ebbesmeyer has become known as the scientist to call with questions about any unusual objects found floating in the ocean.He has even started an association of beachcombers and ocean experts,with 500 subscribers from West Africa to New Zealand.They have recorded all lost objects ranging from potatoes to golf gloves.
32.The underlined phrase swap meets in Paragraph 1 is closest in meaning to.C

分析 本文是一篇说明文.文中介绍了海洋科学家Curtis Ebbesmeyer的一种独特研究洋流的方法--根据海上的漂浮物来研究洋流.他通过寻问海洋搜寻,请他们帮忙来收集漂浮物的信息,用这些信息资料他做实验和研究,不断完善洋流模型的电脑程序设计,然后出版他的研究结果.
解答 32.C.考查词义猜测.和第一段画线短语swap meets的意思更接近的词是什么?根据try and match left and right shoes to sell or wear.可知人们要试穿或卖这些鞋,故推测这是在进行一个交易会.故选C.
33.B.考查细节理解. Ebbesmeyer如何证明他的假设的?根据Ebbesmeyer got to know a lot of them and asked for their help in collecting information about where the shoes landed.可知Ebbesmeyer通过寻问海洋搜寻,请他们帮忙来收集信息,证明他的假设.故选B.
34.B.考查细节理解.Ebbesmeyer以什么最出名?根据Ebbesmeyer has become known as the scientist to call with questions about any unusual objects found floating in the ocean.可知Ebbesmeyer是个著名的科学家,专门打电话寻问罕见的海上漂流物.故选B.
35.D.考查推理判断.作者下这篇文章的目的是什么?根据However,ocean expert Curtis Ebbesmeyer does it in a special way--by studying movements of random floating garbage.可知本文介绍了一种独特的研究洋流的方法--通过研究海洋上的漂流物.故选D.
点评 本篇文章难点在推理判断题上.推理判断题要以表面文字为前提,以具体事实为依据进行推理,做出判断.这种推理方式比较直接,考生只要弄清事实,即可结合上下文推断出合理的结论.
