8、未对选项A 和 C中的相关说法加以这样的限定。选项D 也太绝对了，第 2 段第3 句只是说到 大多数情况下是因为空调设计欠佳所致”，并不是说所有设计良好的大厦就不会发生这种情况。2.A事实细节题。本题考查复合句的理解。只要明白第3段 第2句这个非限制性定语从句中的the bottoms of which中的which是指上文的reservoirs,问题就不难解决了。3.C事实细节题。本题考查被动语态长句的理解。在 第3段 第3句中，关键词是highlight,选 项C是对原句主谓部分的近义替换。选 项A和B在文中皆无提及，选 项D是过度使用生物杀灭剂的后果，与本题干的情况无关。5.C推理判断题

9、。本题考查代词的理解。解题的关键在于理解最后一句中的This是指上一句所说的情况。选 项A中所说的人造环境不是使免疫系统变弱的必然条件。选项B是保持免疫系统健康的条件。选项D是免疫系统变弱后的影响。6月大学英语四级阅读练习及答案（一）Oceanography has been defined as“The application of all sciences to the studyof the sea.Before the nineteen century,scientists with an interest in the sea were few andfar between.Cert

10、ainly Newton considered some theoretical aspects of it in hiswritings,but he was reluctant to go to sea to further his work.It was to Maury of the US Navy that the Atlantic Telegraph Company turned,in1853,for information on this matter.In the 1840s,Maury had been responsible forencouraging voyages d

11、uring which soundings（测身）were taken to investigate thedepths of the North Atlantic and Pacific Oceans.Later,some of his findings arousedmuch popular interest in his book The Physical Geography of the Sea.The cable was laid,but not until 1866 was the connection made permanent andreliable.At the early

12、 attempts,the cable failed and when it was taken out for repairsit was found to be covered in living growths,afact which defied contemporaryscientific opinion that there was no life in the deeper parts of the sea.Within a few years oceanography was under way.In 1872 Thomson led ascientific expeditio

13、n（考-察），which lasted for four years and brought home thousandsof samples from the sea.Their classification and analysis occupied scientists for yearsand led to a five-volume report,the last volume being published in 1895.练习题:Choose correct answers to the question:1.The proposal to lay a telegraph cab

14、le from Europe to America madeoceanographic studies take on.A.an academic aspectB.a military aspectC.a business aspectD.an international aspect2.It was that asked Maury for help in oceanographic studies.A.the American NavyB.some early intercontinental travelersC.those who earned a living from the se

15、a3.The aim of the voyages Maury was responsible for in the 1840s wasA.to make some sounding experiments in the oceansB.to collect samples of sea plants and animalsC.to estimate the length of cable that was neededD.to measure the depths of the two oceans4.“Defied in the 5th paragraph probably means.A

16、.doubtedB.gave proof toC.challengedD.agreed to5.This passage is mainly a b o u t.A.the beginnings of oceanographyB.the laying of the first undersea cableC.the investigation of ocean depths2.D细节题。文章第4段首句为一个强调句，强调的是宾语。题干也是一个强调句型，但强调的是主语。如果把原文的强调句型改为一般的句型，就知道向 Maury 寻求帮助的是 the Atlantic Telegraph Compan

17、y.故答案为 D。A 是 Maury的工作单位，可以排除;原文只提到对于一些早期的穿越洲际的旅行家和依靠海洋维持生计的人，海洋并不遥远，故 B、C 与题意不符。3.D 聿实判断题。文章第4 段提到，19世纪40年代，Maury负责推动进行测深工作的海上航行，以此来探测北大西洋与太平洋的深度.故选Do4.C词义推断题。当时的科学观点是海洋较深的地方不存在生命，而事实上在电缆表面发现了活的生物.由此可知这一事实对当时的科学观点提出质疑，故答案为C。5.A主旨题。通读全文可知，oceanography（海洋学）是全文的中心词，本文主要讲述海洋学是如何起步的，故答案为A o B、C 只表述了原文中个别

18、细节，并非主题;D 跟全文无关。6月大学英语四级阅读练习及答案（九）Not all sounds made by animals serve as language,and we have only to turn tothat extraordinary discovery of echolocation（回声定位）in bats to see a case inwhich the voice plays a strictly practical role.练习题：Choose correct answers to the question:l .The main purpose of th

19、is passage is to.A.describe that animals can make different soundsB.prove that animals voices can play practical rolesC.inspire the readers to make more inventionsD.startle the readers with some shocking facts2.The discovery of echolocation may help with all of the following EXCEPTA.measuring the de

20、pth of the seaB.distinguishing different kinds of fishC.improving the functions of radarD.varying the size and nature of an object3.By saying A shoal of fish will do this(Lines 6-7,Para.2),the author meansA.only one special kind of fish can reflect soundsB.only one special kind of fish can be used t

21、o help locate a shipC.a large group of fish can reflect soundsD.a large group of fish can be used to help locate a shipA.human languagesB.a mountainsideC.a shoal of fishD.taps on a ship5.Which of the following statements can be inferred from the passage?A.Animals are more intelligent than humans.B.H

22、umans are more intelligent than animals.D.Humans are often inspired by animals.l .B主旨大意题。文章第1段就点明主题，明确指出以蝙蝠为例，动物发出的声音有实际作用，只有B可以概括文章的这个写作目的。2.C事实细节题。本题考查列举处，可用排除法解答。A、B、C在文中都有相关提及。D利用第2段中的varying制造干扰。在原文中，指的是回声因障碍物的不同而不同，而D偷换概念、曲解文意，D中的varying为及物动词，意为 改变显然不可能是回声定位的发现带来的功效。3.C词义推断题。本题考查对shoal的词义推测及代词

23、this的理解。依据第2段最后几句话，可推测出a shoal offish指的是“海里的一群鱼”;this则是指上一句提到的 任何固体都可以反射声音，因此这句话表明一大群鱼就能像一个固体一样反射声音。4.D推理判断题。根据最后一段可知，蝙蝠发出吱吱声可以探测障碍物的距离，而 第2段也指出轻敲船体可测知海底的距离，因此在功能上,D与蝙蝠的吱吱声相同。A中的human languages在文中未提到;B和C在文中各自的例子中充当的都是障碍物的角色，因此都不正确。5.D推理判断题。文章先说动物的回声定位功能，再说到回声定位探测仪的发明，由此可见，是动物的某些能力启发了人类的创造，因此只有D可从文中推

24、测。文章并没有从智力方面比较人类和动物，因此可以排除A和B;尽管文章说到了蝙蝠和雷达的原理相似，但是C中的。ften 一词无据可循，且C的说法浮于表面，没有说到重点，故排除。6月大学英语四级阅读练习及答案（四）Where do pesticides fit into the picture of environmental disease?We haveseen that they now pollute soil,water and food,that they have the power to makeour streams fishless and our gardens and wo

33、us signs are easy to cureD.people tend to overlook hidden dangers caused by pesticidesl.B 题干的句子是文章第1 段第3 句，这是一个带有插入语的简单句,contrary在此表示跟part of nature相反,因此答案为B。3.A第 2 段第2 句提到，杀虫剂使人突然发病或者死亡是很令人难过的事，对于人口整体来说，人类对杀虫剂长期累计的潜在后果的认识不足，才是最严重的问题，故选A。4.C根据第3段倒数第2句说的“对未来的灾难无动于衷是人的本性 以及最后一句说的“大多数人只对有明显迹象的疾病予以关注 可知

34、C 正是人们忽视化学药物的潜在危害的原因，故选C。5.D Dubos博士话中 最可怕的敌人 指的是 杀虫剂引起的潜在危险，博士话中的 slowly approach them unnoticed 直接表明 D 正确。6月大学英语四级阅读练习及答案（七）Deeply involved with this new technology is a breed of modern business peoplewho have a growing respect for the economic value of doing business abroad.Inmodern markets,succe
