第二篇　Water　Pollution　and　Man 
Water　pollution　affects　man’s　health,　recreational　use　of　water,　industrial　of　water　and　sense　of　beauty. 
The　spread　of　water-carried　disease　is　of　great　concern.　In　highly　developed　countries　in　particular,　emphasis　has　shifted　from　concern　over　bacterial　disease　to　concern　over　water-carried　viral　(病毒性的)　disease.　Viral　hepatitis　(肝炎),　for　example,　has　been　found　to　occur　more　frequently　in　cities　whose　water　supplies　have　comparatively　high　levels　of　water　impurity.　Poisonous　chemicals　found　in　streams　that　are　ultimately　used　for　water　supplies　also　create　an　important　public　health　problem. 
It　is　clear　that　poisonous　chemicals　must　be　excluded　from　water,　but　more　and　more　chemicals　from　new　pesticides,　fertilizers,　and　other　new　products　have　been　found　in　water.　Since　the　public　health　significance　of　these　chemicals　is　not　yet　fully　known,　they　are　of　increasing　concern.　The　chemicals　from　fertilizers　are　also　finding　their　way　into　water　supplies　from　groundwater　pollution. 
As　man’s　desire　for　water-based　recreation　increases,　greater　demands　are　placed　on　the　quality　of　water.　The　water　must　not　only　be　attractive　in　appearance　but　also　meet　certain　other　conditions.　Sports　such　as　swimming　involve　direct　contact　with　water,　and　so　water　standards　are　raised　higher. 
The　range　of　water　quality　necessary　for　industrial　processes　varies　greatly　with　the　intended　use　of　to　water.　The　water　used　in　steel　mills,　for　example,　must　have　a　lower　chloride　(氯物)　level　than　that　accepted　for　drinking　water.　Cooling　water　can　often　be　of　comparatively　low　sanitary　quality.　A　large　part　of　the　water　used　in　the　paper-making　industry　can　be　of　relatively　low　quality　in　some　aspects,　but　must　contain　little　iron　and　carbon　dioxide. 
41.　According　to　the　passage,　the　people　in　highly　developed　countries　today　are　most　concerned　about　_________. 
○A.　bacterial　disease 
○B.　water-carried　disease 
○C.　poisonous　chemicals　in　streams 
○D.　water　impurity 
42.　The　chemicals　from　pesticides　and　fertilizers　found　in　water　are　of　increasing　concern　because　____________. 
○A.　Their　significance　to　man’s　health　has　not　been　completely　known. 
○B.　they　may　cause　groundwater　pollution 
○C.　they　can　find　their　way　into　water　supplies　for　farmers 
○D.　they　are　important　factors　contributing　to　the　spread　of　disease 
43.　According　to　the　passage,　water-based　recreation　demands　that　_______. 
○A.　the　water　contain　a　higher　level　of　oxygen 
○B.　the　water　contain　little　iron　and　carbon　dioxide 
○C.　the　water　be　attractive　and　of　high　quality 
○D.　the　water　standards　be　appropriate　for　all　sports 
44.　In　the　last　paragraph,　the　author　mentions　all　of　the　following　except　_________. 
○A.　water　quality　necessary　for　steel　mills 
○B.　soft　water　and　hard　water　for　industrial　processes 
○C.　cooling　water　of　low　sanitary　quality 
○D.　water　standards　for　paper　mills 
45.　As　the　passage　is　not　complete,　that　do　you　think　would　follow　in　its　full　text? 
○A.　The　relationship　between　carbon　dioxide　and　paper　making. 
○B.　Water　pollution’s　direct　economic　effects　on　man. 
○C.　Examples　of　continued　water　pollution. 
○D.　Man’s　views　on　water　pollution　in　terms　of　beauty　values.

Crime　and　Drugs 
Despite　the　respect　of　most　Americans　for　law　and　the　determination　of　the　legal　system　to　protect　the　rights　of　individuals,　the　United　States,　like　all　other　countries,　does　experience　crime.　Especially　in　large　cities,　the　c　46　rate　can　be　high. 
A　high　percentage　of　crime　in　the　United　States　in　directly　related　to　the　illegal　sale　and　u　47　of　drugs.　Drugs　are　smuggled　i　48　the　country　by　organized　groups　of　criminals　despite　intense　efforts　by　the　government　to　stop　the　illegal　drug　trade.　T　49　who　become　addicted　to　drug　use　sometimes　rob　or　break　into　houses　or　stores　to　get　money　to　pay　f　50　the　drugs. 
Drug　use　has　caused　great　concern　i　51　the　United　States.　The　federal　government　has　worked　hard　to　stop　the　growing　of　drug　plants　in　other　c　52　.　It　has　also　set　up　special　agencies,　sometimes　working　with　agencies　from　o　53　nations,　to　catch　the　smugglers　outside　and　inside　the　United　States.　Teachers　and　many　other　citizens　work　together　to　t　54　children　about　the　dangers　of　drug　use.　Many　government　agencies　in　the　states　and　private　citizen　groups　work　to　help　drug　addicts　give　u　55　their　drug　use　and　turn　to　useful　lives.
