3.M4,GA giftof thegods.According to an oldGreek myth,Prometheus andhis brother,Epimetheus,heroes ofa raceofgiants calledthe Titans,were giventhe taskof creatingman.Epimetheus was also toprovide allthe animalswithmeans ofdefense orflight.To somehe gavecourage,strength,and clawswith whichto fight,and to others(慷慨的)long legs,nimble feet,or wingswith whichto escape.So lavishwas hewith thesegifts to the loweranimalsthat hehad nothingleft togive toman.Prometheus,however,was determinedthat manshould notbeneglected andso,according to the myth,he gainedaccess toheaven and1ighted his torch atthe chariotofthe sun.Returning toearth,he presentedfire toman,and withthis giftcame man,s dominionover alltheearth.The firstcook.It tooka longtime,however,to learnhow touse thisgift.For centuriesmen livedlike wildanimals.Their foodconsisted ofnuts,herbs,fruit,and theflesh ofanimals.Cooking wasunknown,and whenawild animalwas captured,the savagetore itapart and ate theraw flesh.According toone legend,a hunter,(缓慢燃烧的)after along tramp,succeeded incatching arabbit.On hisway homehe founda smolderingfirewhich hadbeen started by lightning.Throwing hisrabbit ona log,he laydown andwent tosleep.When heawoke,he foundthat hisrabbit hadfallen into the fire.In attemptingto rescueit,the savagegot someofthejuiceof theroasted rabbiton hisfingers.By instinct,he puthis burntfingers tohis mouth,and thetaste wassopleasing thathe immediatelyfinished therabbit,and thisis howman learnedto cook.Reduction ofmetals.Ages later,man begantousefire to make metalsand toform theminto spearsand hatchetsforhunting andfighting.The alchemists,as weknow,used firein theirattempts tochange thebase metalsintogold,and todayfires areburning inmany furnacesproducing,if notgold,metals offar greatervalueto theprogress ofcivilization.Copper,bronze,iron,and steel,produced byfire,have beenthe steppingstonesof mans progressthrough theages.The chemistryinvolved inthe extraction,purification,and alloyingofmetals isso interestingand ofsuch greatimportance thatvolumes have been writtenon thissubject.Heating homes.We are so accustomedto livingin heatedhomes thatit isonly whensomething goeswrong withthe furnace thatwe giveany thoughtto theblessed fire.To thesavage shiveringin hiscave,however,a firewas a realblessing,even ifit didfill hiseyes withsmoke.Keeping thehome firesburning第wasadifficult taskfor theAmerican Indian,who delegatedthis tohis wife.Woe beto thesquaw E[1安女子或妻子who letthe firego out.In thewintertime,the firewas builtontheground inthe centerofthe tent,which hada smallhole inthe topto actasasmokestack.Even thepalaces ofthe wealthyin theMiddle Ages were cold anddamp,the fireplacesbeing soinefficient thatonlyaportion ofone roomcould beheatedata time.Not untila comparativelyrecent date1742were stovesinvented,and furnaceswere unknownevenwhen yourgrandfather wasa boy.How firesare startedand stopped.You havelearned thatburning israpid oxidationwhich givesoff lightand heat.In orderto start a fire,three conditionsare necessary1something toburn;2something tosupportthe combustion;and3a meansof lightingthe fuelraising itto itskindling temperatureHaving livedallhis lifeinahome wherethefurnaceis keptburning allwinter,the averageperson seldomthinks ofthedifficulty ofstarting a fire.To getsome idea ofthedifficulty ofstarting fires,imagine yourselfshipwrecked likeRobinson Crusoeuponan uninhabitedisland.To builda fire,the firstcondition would be metby collectingsome wood.The secondconditionwouldbeno problemas air

byrubbing twodry stickstogether.This soundssimple,but muchskilland practiceare essentialtothesuccess ofthis operation.The secondmethod isto makesparks bystriking极硬的东西,燧石two piecesof flinttogether.This maywork ifthe operatoris persistentand ifhis fuelissufficiently fineand dry.But beforehe succeeds in gettingafirestartedbyeither method,our RobinsonCrusoewill dosome thinkingabout theusefulness ofthe commonmatch.Poison matches.There aretwo kindsof phosphorusused in making matches,white andred.White phosphorushasan advantageandadisadvantage.White phosphorus is cheaperand,at onetime,its usewas quitecommon.Whitephosphorus ispoisonous,however,and forthis reasonits use inmakingmatches isprohibited bylaw innearlyall civilizedcountries.Men working in match factories whichused whitephosphorus weresubject to a diseasewhichcaused the jaw bonesto decay.The dangerof smallchildren beingpoisoned bythese matches is alsoevident.Fortunately,chemists havediscovered amethod of making aform ofphosphorus which is not poisonous.Whenwhite phosphorusis gentlyheated forseveral hoursinaclosed vesselfrom whichairisexcluded,it slowlychangesin colorand theno-poisonous red phosphorusisformed.In additiontothefactthatit is notpoisonous,redphosphorushas otheradvantages.Its kindling temperature ismuch higherthan thatofthewhite variety,and thismakes redphosphorus lessdangerous toship and to

notpoisonous.
