46、 thecostsofwaterredistributionshouldbeconsideredD. watercanbeeasilycarriedthroughpipesacrosstheworld答案:C解析:推理判断题。根据文章第一段可知人口的不断增长给淡水的供应带来了压力。第二段提到了解决水源缺乏的办法,但解决办法所付出的代价是巨大的,这不仅仅要考虑工程本身的代价,还要考虑对自然环境的破坏所付出的代价。据此推断答案为C项。根据第一段第二句话可知A项错误;第一段中的“someonefortunateenoughtoliveinahighrainfallcountry.意思并非是说降水量大

47、的地区的人们自身感到幸运,故B项错误;根据文章第二段倒数第二句话可知D项错误。W30.WhichofthefollowingisTRUE?A. ThewaterstoresinTexashavebeenreducedby75%.B. Mostindustriesintheworldsufferfromwatershortages.C.

48、解题。根据最后一段最后一句话中的“.anditisbelievedthatfiftyyearsofpumpingwillseethemrundry.可知C项正确;第三段第二句话提到水源储存减少了25%,而不是75%由此可知A项错误;根据第一段最后一句中的manyoftheworldsagriculturalindustries.可知B项中的Mostindustries有误;根据倒数第二段最后一句话可知D项与文中叙述内容相反。J31.Whatismostlikelytobediscussedintheparagraphthatfollows?A. Stepstoimprovingwateruse

49、management.B. Waystoreducethecostsofbuildingdams.C. Measurestodealwithworldwidewatershortages.D. Approachestohandlingthepressureonwatersupply.答案:A解析:推理判断题。文章第一段指出淡水资源的贫乏问题,第二段作者提出了解决水源贫乏问题的唯一可行的办法就是依靠对水源的管理,第三、四段分别介绍了两个国家在水源管理中出现的弊端。据此推断接下来作者可能会具体谈改善水源利用的管理措施。故选A项。L32.Thetextismainlyabout.A. watersu

50、pplyandincreasingpopulationB. waterusemanagementandagricultureC. waterredistributionandwildlifeprotectionD. watershortagesandenvironmentalprotection答案:B解析:主旨大意题。第一段介绍了淡水资源匮乏与农业生产;第二段介绍了解决办法与农业灌溉;第三段介绍了美国农业灌溉用水管理中显现的问题;第四段介绍了沙特阿拉伯利用地下水进行农业灌溉显现的问题。综合上述分析不难判断本文主要讲述的是水资源管理与农业。虽然A、C、D三项中的内容文中有所提及,但都不能概括全

51、文主旨。故选B项。第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。Whatisayawn哈欠)andwhydopeopleyawn?Ayawnisoftenassociatedwithapersonbeingtired33.Peopleyawnformanyreasonsincludingstress,boredom,emotionandoverwork.Haveyounoticedthatyawningseemstobecontagiou会传染的)?lfonepersonyawns,thisappearstocaus
