外研版高一年级(必修1)Module5如何写英文实验报告【案例呈现】按照下列说明写一篇英文实验报告。实验目的：探究噪音是否会对植物产生影响。实验用品：若干盆同种植物，长势相同。实验方法：将该同类植物分成A组和B组，提供给它们相同的生长环境，但是每天都给B组“听”90分贝的噪音，观察A组和B组植物的生长情况。实验结果：数天后，B组植物渐渐枯萎，而A组的依然正常生长。实验结论：噪音会对植物的生长造成危害。注意：1.词数：100左右；2.参考词汇：盆pot；分贝decibel；枯萎wither。【写作指导】●审题定调：实验报告属于说明文体裁，其最大特点就是知识性和科学性。它是对客观事实的阐述，措辞严谨真实，准确恰当。时态主要为一般现在时态；人称一般用第二人称。●布局谋篇：全文分三段式（题目可省略）第一段：说明实验的目的和所需要的实验用品。第二段：实验的方法或实验的过程。第三段：实验的结果和结论。●常用表达:1.描写实验目的:inordertofind;Theaimoftheexperimentistofind;withthepurposeofdiscovering;doresearchon;inthehopeof...2.描写实验用品:Tocarryout/make/do/performtheexperiment,youshouldneedsomepotsofflowersand...;Thefollowingthingsareneeded;Whenallthethingsareready,youcanbegintheexperiment.3.描写实验方法或过程：makegoodpreparationsfor;Itisimportantthat;dotheexperimentasfollows;firstly;secondly;thirdly;finally;first;then;next;afterthat;twohours’later;afterseveraldays;findabetterwayofdoing;beunderobservation;makeagoodstudyof...4.描写实验结论：fromthisexperimentwecanconclude;inconclusion;drawaconclusionthat;Wecanlearnfromtheexperiment...;Wecanfindoutthat...;Youcansee/discover...5.描写原因和结果：Thereasonisthat...;Thisisbecause...;resultfrom/in;leadto;cause...【范文欣赏】Theaimoftheexperimentistodiscoverwhethernoisedoesharmtotheplants.Tocarryouttheexperiment,youneedsomepotsofthesamekindofplants,whosegrowingsituationisthesame.First,dividetheplantsintotwogroups:GroupAandGroupB.Thenputtheminthesamegrowingenvironment.ButletGroupBlistentosomenoisewhichreaches90decibels.Next,observehowtheplantsgrowinthefollowingdays.Afterseveraldays’observation,youcanfindtheplantsofGroupBwithergraduallywhiletheplantsofGroupAgrownormally.Fromthisexperimentwecanconcludethatnoisecandogreatharmtothegrowthoftheplants.
