Question

8．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 random 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（海灘搜尋） 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 1，600shoes．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 500subscribers from West Africa to New Zealand．They have recorded all lost objects ranging from potatoes to golf gloves．

41．The underlined phrase swap meets in Paragraph 1 is closest in meaning toB．
A．fitting rooms
B．trading fairs
C．business talks
D．group meetings
42．Ebbesmeyer phoned the shoe company to find outC．
A．what caused the shipping accident
B．when and where the shoes went missing
C．whether it was all right to use their shoes
D．how much they lost in the shipping accident
43．How did Ebbesmeyer prove his assumption？A
A．By collecting information from beachcombers
B．By studying the shoes found by beachcomber
C．By searching the web for ocean currents models
D．By researching ocean currents data in the library
44．Ebbesmeyer is most famous forD．
A．traveling widely the coastal cities of the world
B．making records for any lost objects on the sea
C．running a global currents research association
D．phoning about any doubtful objects on the sea
45．What is the purpose of the author in writing this passage？C
A．To call people's attention to ocean pollution
B．To warn people or snipping safety in the ocean
C．To explain a unique way of studing ocean currents
D．To give tips on how to search for lost objects on the beach．

Answer 1

分析 本文是說明文，文中介紹了海洋科學家Curtis Ebbesmeyer的一種獨特研究洋流的方法--根據(jù)海上的漂浮物來研究洋流．他通過尋問海洋搜尋，請他們幫忙來收集漂浮物的信息，用這些信息資料他做實驗和研究，不斷完善洋流模型的電腦程序設計，然后出版他的研究結(jié)果．

解答 41．B     考查詞義猜測．根據(jù)畫線詞所在句中的"tryand match left and right shoes to sell or wear"可推斷出"swapmeets"應該是"市集"，選項中的"tradingfairs"有"交易會"之意，故選B．
42．C     考查推理判斷．根據(jù)文章第二段第二句"Hephoned the shoe company and asked if they wanted the shoes back"可知他打電話的目的是問公司是否要這些鞋子．結(jié)合下文中的"Ebbesmeyerrealized this could be a great experiment．If he learned when and where theshoes went into the water and tracked where they landed，he could learn a lotabout the patterns of ocean currents"可知，Ebbesmeyer是想用這些鞋子，故選C．
43．A    考查細節(jié)理解．由文章第三段中的"askedfor their help in collecting information about where the shoes landed"以及"Withthis data，he and his colleague were able to test and improve…"可知選項A正確．
44．D    考查推理判斷．文章最后一段第一句中的"Ebbesmeyerhas become known as the scientist to call with questions about any unusualobjects found floating in the ocean"可知，Ebbesmeyer已經(jīng)成為一位知名科學家，一旦發(fā)現(xiàn)海上有不尋常的漂浮物時，人們都會打電話咨詢他．故答案為D．
45．C    考查主旨大意．文章開頭指出：大多數(shù)科學家研究洋流時，大多使用衛(wèi)星和其他高科技設備，但CurtisEbbesmeyer 則不同．至于如何不同，文章在后面幾段有詳細說明．故選C．

點評 解答細節(jié)理解題時，一個常用的方法就是運用定位法，即根據(jù)題干和選項中的關(guān)鍵詞從原文中找到相關(guān)的句子，與選項進行比較從而確定答案；推理判斷題既要求學生透過文章表面文字信息推測文章隱含意思，又要求學生對作者的態(tài)度、意圖及文章細節(jié)的發(fā)展作正確的推理判斷，力求從作者的角度去考慮，不要固守自己的看法或觀點．
