　　【小题1】B

　　【小题2】C

　　【小题3】A

　　【小题4】D

　　【小题5】C解析

　　分析：

　　本文是一篇说明文。文中介绍了海洋科学家CurtisEbbesmeyer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。

　　【小题1】B.考查词义猜测。和第一段画线短语swapmeets的意思更接近的词是什么？根据tryandmatchleftandrightshoestosellorwear.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B。

　　【小题2】C.考查推理判断。Ebbesmeyer给这些鞋的公司打电话是为了确定什么？根据Asexpectedthecompanytoldhimthattheydidn't.Ebbesmeyerrealizedthiscouldbeagreatexperiment.Ifhelearnedwhenandwheretheshoeswentintothewaterandtrackedwheretheylandedhecouldlearnalotaboutthepatternsofoceancurrents.可知他打电话问公司要不要这些鞋，公司说不要。他觉得这可能是一个巨大的实验。如果他能知道这些鞋是何时下水的，何时登陆的，那他就可以推断洋流的形式。这样，打电话最根本的目的是确定“能用你们的鞋子吗？能用我就用来实验了。”故选C。

　　【小题3】A.考查细节理解。Ebbesmeyer如何证明他的假设的？根据Ebbesmeyergottoknowalotofthemandaskedfortheirhelpincollectinginformationaboutwheretheshoeslanded.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A。选项B通过研究海洋搜寻发现的鞋。根据Inayearhecollectedreliableinformationon1600shoes.Withthisdataheandacolleaguewereabletotestand可知他用这些鞋的信息做实验，故排除B项。选项C通过上网搜寻洋流的模型。根据improveacomputerprogramdesignedtomodeloceancurrents可知他自己不断完善洋流模型的电脑程序设计，不是在网上搜的洋流模型，故与原文不符。选项D通过在图书馆研究洋流资料。文中没有提到他在图书馆的学习研究，故排除D项。

　　【小题4】D.考查细节理解。Ebbesmeyer以什么最出名？根据Ebbesmeyerhasbecomeknownasthescientisttocallwithquestionsaboutanyunusualobjectsfoundfloatingintheocean.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D。

　　【小题5】C.考查推理判断。作者下这篇文章的目的是什么？根据HoweveroceanexpertCurtisEbbesmeyerdoesitinaspecialway--bystudyingmovementsofrandomfloatinggarbage.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C。考查：科普类短文阅读。
