  23. Too much ________ to X-rays can cause skin burns, cancer or other damage to the body.

  [A] disclosure [B] exhibition [C] contact [D] exposure

  正确答案是(D)

  题目分析:(A) disclosure:close为"关闭"之意, disclose的含义是"揭露, 透露"。(B) exhibition: "展览,表演",一般用于exhibition of ...表示:"……的展览",或on exhibition: "在展览中"。(C)contact:"接触,联系",用于contact with :"同……接触"。(D)exposure :"暴露;揭露;接触",用于词组exposure to : "暴露于……中"。根据上下文及用词搭配,都应该选(D)exposure。

  24. When confronted with such questions, my mind goes __________, and I can hardly remember my own date of birth.

  [A] dim [B]blank [C] faint [D] vain

  正确答案是(B)

  题目分析:(A)dim:" 昏暗的,模糊的",go dim:指"(脑子)变得混沌不清楚。"(B)blank: "空白的",go blank指"(头脑)变成一片空白",与后面"我几乎记不起来我自己的生日"意思相吻合,故应选(B)。(C)faint : "衰弱的,昏晕的",go faint :一般指"(身体)发晕";(D)vain :"空费的,徒劳的;自负的"。一般不与go搭配,短语in vain是“徒劳的,白白的”。

  25. It is well known that knowledge is the _________ condition for expansion of mind.

  [A] incompatible [B] incredible [C] indefinite [D] indispensable

  正确答案是(D)

  题目分析:(A)incompatible: "不能共存的,不相容的"。(B) incredible:"难以置信的;不可思议的"。(C)indefinite: "含糊的;不明确的"。(D)indispensible:"必不可少的;必需的"。此题目译为:大家都知道,知识是扩充头脑的必不可少的条件。It是形式主语,that引导的是主语从句。根据上下文判断,(D)是最合适的答案。

  26. More than two hundred years ago the United States __________ from the British Empire and became an independent country.

  [A] got off [B] pulled down [C] broke away [D] attached to

  正确答案是(C)

  题目分析:此题目考查词组意义。(A)got off : "下来,出发,动身"。(B)pulled down:"拆毁;拖垮"。(C)broke away(from): "脱离,摆脱",根据上下文,应选(C)。(D)dropped off :"陆续散去,睡着"。

  27. Care should be taken to decrease the length of time that one is ________ loud continuous noise.

  [A] subjected to [B] filled with [C] associated with [D] dropped off

  正确答案是(A)

  题目分析:(A)(be)subjected to : "遭受,受到,服从"。 (B)(be ) filled with : "充满了"。(C)(be) associated with: "与……联系在一起"。(D)(be) attached to:"附属于,依恋于"。显然是(A)"遭受到极大的不断的噪声"为最合理。

  28. Some of the most important concepts in physics ________their success to these mathematical systems.

  [A] oblige [B]owe [C]contribute [D]valuable

  正确答案是(B)

  题目分析:(A)oblige ...(to do):"强迫……做某事"。Oblige还有“施惠;帮…的忙”的含义,例如:Please oblige me by closing the door.请帮我把门关上。I'm much obliged to you.我非常感谢你帮忙。这一用法是2004年考研英语翻译第62题的一个重要考点。(B)owe ....(to ):"多亏,感谢,把…归功于"。(C)contribute...(to):"献出,把……花费在……",contribute to导致,造成。(D)attribute...(to):"把……归属于……"。显然,(B)为正确答案。这句话的意思为:一些物理学中最重要的概念的成功应该归功于这些数学体系。而不能把物理学中概念的成功"归属于"数学体系。

  29. As your instructor advised, you ought to spend your time on something __________ researching into.

  [A] precious [B] worth [C] worthy [D] valuable

  正确答案是(B)

  题目分析:(A) precious:"宝贵的;完全的"。(B)worth:"值得的"。worth后面一般跟动名词表示"值得做某事",并且用主动形式表达被动的含义,而(C)worthy也表示"值得做某事"时,一般的用法是worthy of sth.或worthy to be done。此外,worthy有受人尊敬的意思,这一含义,在2006年考研阅读理解第二篇文章第二段从到了这一含义,“the worthy residents”. (D)valuable:"有价值的,贵重的",比较词义和用法,(B)为最佳答案。

  30. As a defense against air-pollution damage, many plants and animals _________ a substance to absorb harmful chemicals.

  [A] relieve [B] release [C] dismiss [D] discard

  正确答案是(B)

  题目分析:(A) relieve:"减轻, 解除, 援救, 救济"。(B)release:"释放;免除;发行,发布"。(C)dismiss"解散;解雇;消除"。(D)discard:"抛弃,解雇"。此题目意思是:作为对空气污染的防护措施,许多植物和动物释放出一种可以吸收有害化学成分的物质。因此应选择(B)。against是1998年完形填空的43题的考点。
