ed the shoe pany and asked if they wanted the shoes expected,the pany told him that they didn’ realized this could be a great 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 beachbing (海滩搜寻 )because winds and currents join here,and as a result,there is a group of serious beachbers in the got to know a lot of them and asked for their help in collecting information about where the shoes a year he collected reliable information on 1,600 this data,he and a colleague were able to test and improve a puter program designed to model ocean currents,and publish the findings of their study. As the result of his work,Ebbesmeyer has bee known as the scientist to call with questions about any unusual objects found floating in the has even started an association of beachbers and ocean experts,with 500 subscribers from West Africa to New have recorded all lost objects ranging from potatoes to golf gloves. underlined phrase“swap meets” in Paragraph 1 is closest in meaning to . rooms fairs talks meetings 答案 :B 解析 :词义猜测题。 swap 意思是 “ 交换 ”, 由相似表达 sports meet 可以推出 meet 的含义 ,再从文中 “There were so many sho es that people were setting up swap meets to try and match left and right shoes to sell or wear.” 可以确定答案为 B 项。 trading 的意思是 “ 交易 ”。 fair 意思是 “ 集市 ”。 phoned the shoe pany to find out . caused the shipping accident and where the shoes went missing it was all right to use their shoes much they lost in the shipping accident 答案 :C 解析 :细节理解题。 根据第二段第二句 “He phoned the shoe pany and asked if they wanted the shoes back.” 可知埃贝斯迈尔给制鞋公司打电话问他们还要不要收回这些鞋子 ,再结合下文 “Ebbesmeyer realized this co uld be a great experiment.” 可以得出他打算利用这些鞋子进行研究。 故选 C项。 did Ebbesmeyer prove his assumption? collecting information from beachbers. studying the shoes found by beachbers. searching the web for ocean currents models. researching ocean currents data in the library. 答案 :A 解析 :细节理解题。 根据第三段中的 “...there is a group of serious beachbers in the got to know a lot of them and asked for their help in collecting information about where the shoes landed.” 可知埃贝斯迈尔是从海滩搜寻者那里得到信息的。 故选 A项。 is most famous for . widely the coastal cities of the world records for any lost objects on the sea a global currents research association about any doubtful objects on the sea 答案 :D 解析 :细节理解题。 根据 最后一段中的 “...Ebbesmeyer has bee known as the scientist to call with questions about any unusual objects found floating in the has even started an association of beachbers and ocean experts” 可知答案为 D项。 其中 call对应 phone,unusual 对应 doubtful。 C (2020重庆 ,C) The idea of being able to walk on water has long interested humans ,biological facts prevent us ever acplishing such a thing without artificial aid— we simply weigh too much,and all our mass pushes down through our relatively small feet,resulting in a lot of pressure that makes us sink. However,several types of animals can walk on of the most interesting is the mon basilisk Basilicus basilicus,a lizard(蜥蜴 ) native to Central and South can run across water for a distance of several meters,avoiding getting wet by rapidly hitting the water’s surface with its lizard will take as many as 20 steps per second to keep moving humans to do this,we’d need huge feet that we could bring up to our ears in order to create adequate “hitting.” But fortunately there is an alternative: adding enough of this mon thickening agent to water(and it does take a lot),you can create a “non Newtonian” liquid that doesn’t behave like normal ,if the surface of the water is hit hard enough,particles(粒子 ) in the water group together for a moment to make the surface quickly enough and put enough force into each step,and you really can walk across the surface of an adequately thick liquid of cornflour. Fun though all this may sound,it’s still r ather messy and better read about in theory than carried out in you must do it,then keep the water wings handy in case you start to sink— and take a shower afterward! on water hasn’t bee a reality mainly because humans . not interested in it biological limitations not invented proper tools afraid to make an attempt 答案 :B 解析 :细节理解题。 根据第一段第二句可知 ,人类在水面上行走的想法无法实现的主要原因是生物的局限性 :人们的身体太重 ,水面无法承受这种压力。 do we know about Basilicus basilicus from the passage? is light enough to walk on water. huge feet enable it to stay above water. can run across water at a certain speed. unique skin keeps it from getting wet in water. 答案 :C 解析 :细节理解题。 根据第二段第三、四句可知 ,这种生活在中美洲和南美洲的蜥蜴能够以20步 /秒的步频在水面飞跑。 这样的步频能达到一定的速度。 is the function of the cornflour according to the passage? create a thick liquid. turn the water into solid. help the liquid behave normally. enable the water to move rapidly. 答案 :A 解析 :推理判断题。 根据第三段第二句和最后一句可推断出 ,这种玉米淀粉的作用是让液体变得黏稠。 thickening agent“ 增稠剂 ”。 is the author’s attitude toward the idea of humans’ walking on water? is risky but beneficial. is interesting and worth trying. is crazy and cannot bee a reality. is impractical though theoretically possible. 答案 :D 解析 :推理判断题。 根据最后一段第一句可推断出 ,作者认为 ,人类在水面上行走的想法是不切合实际的 ,虽然这一想法在理论上似乎可行。 D For an island experience just taking a few minutes by ferry from Victoria Point,why no。
