　　一项简单的调查揭露，人为因素仍然是主要的原因。比如，其中三起事故都是由于学生使用热得快引起的。由于学生经常让热得快处于无人看守状态，如果瓶中的水烧干却没有人在旁边拔掉电源的话风险是相当高的。其他情况，如火炉，蜡烛，烟头等也会引起火灾。

　　因为如果能够采取适当的预防措施，大部分的这些灾难本可以避免的，所以学生应该更好地被教育控制火灾的重要性以及措施。以下三个警告对我们学生尤其重要：第一，学会如何使用灭火器。第二，仔细检查蜡烛，热水器，炉具及其他电器，并确保在离开房间之前没有明火。最后，不要在寝室内吸烟。

　　Atfirst,youmustunderstandthemeaningofclimatechange.Itmeansanylong-termsignificantchangeintheaverageweather,whichmayincludeaveragetemperature,precipitation,windpatternsandsoon.Forexample,Australiaisexperiencingrapidclimatechange.Sincethemiddleofthetwentiethcentury,Australiantemperatureshaverisenbyaboutaverageonetemperaturedegreewithanincreaseinthefrequencyofheatwavesandadecreaseinthenumbersoffrostsandcolddays.Rainfallpatternshavealsochanged,whichmeansthatthenorthwesthasseenanincreaseinrainfalloverthelastfiftyyearswhilemuchofeasternAustraliaandthefarsouthwesthaveexperiencedadecline.Fromthisexample,itindicatesclimatechangethatisoccurringtodayhasspedup,andaffectslong-termweather.TheEarth’sclimateislargelyaffectedbyhowmuchheatisstoredintheatmosphere.Furthermore,theclimatechangeiscausedbydynamicprocessonEarth,externalforcesincludingvariationsinsunlightintensity,andmorerecentlybyhumanactivities.

　　Themostimportantreasonofclimatechangeiscausedbyhumans,becausehumansproducealotofcarbondioxideintotheair.Thiscarbondioxideemitsfromfossilfuel,aerosols,cementmanufacture,landuse,animalagricultureanddeforestation.Forexample,treescantakeincarbondioxidetoproduceoxygenbyphotosynthesis.Ifpeoplecutmanytreesformakingfurniture,paper,orsellwoodtomakemoney,thereismuchmorecarbondioxideintheair.Beginningwiththeindustrialrevolutioninthenineteenthcenturyandacceleratingeversince,thehumanconsumptionoffossilfuelshasraisedcarbondioxidelevelsrapidly.Itmeansthatcarbondioxidelevelsaresubstantiallyhighernowthanbefore.Ontheotherhand,duringtheprocedureofmanufacturingcement,whichisusedinbuildings,significantlymorecarbondioxideisproduced.Whilepeopleimprovetheirlivingstandard,theycauseclimatechange.Whenpeopleburncoal,oil,andgasforourelectricity,carbondioxideisproduced.Whenpeopleburnfossilfueltomovevehicles,carbondioxideisalsoproduced.Thesesortsofexamplesindicatethathumansaretherealculprit.Theydonotconsidertheconsequence,whiletheyenjoyproducingeverythingtheywant.
