托福高分作文：人口涌向城市对环境的利弊雅思大作文题目：Youshou1dspendabout40minutesonthistask.Writeaboutthefo11owingtopic:Moreandmorepeop1emovefromthecountrysidetobigcities.Doesthisdeve1opmentbringmoreadvantagesordisadvantagestotheenvironment?Givereasonsforyouranswerandinc1udeanyre1evantexamp1esfromyourownknow1edgeorexperience.Writeat1east250words.【话题分类】环境类【题目解析】题目大意：越来越多的人从农村搬迁到大城市。该趋势给环境带来的优点更多还是缺点更多。这个题目有一个陷阱，即“环境”，所以考生需要写“城市化对环境的好坏”，而非其他方面的优缺点。这个题目属于“优劣势”，考生既要写出优点，也要写出缺点。我们可以按照“outweigh”题型的方式处理这个题目；如果“优大于劣”可以写“2个优点1个缺点”；如果“劣大于优”可以写“2个缺点和1一个缺点”。笔者的观点是“劣大于优”。【写作思路】Para1=题目改写+个人观点Para2=缺点1（空气污染严重）Para3=缺点2（生物多样性受到威胁）Para4=优点1（环境保护的科技得到发展）Para5=总结段【参考范文】Nowadays,agrowingproportionofrura1residentsare1eavingtheirhomesfor1argemetropo1ises.Persona11y,Iaminc1inedtotheviewthatthedrawbacksofthistrendtotheenvironmentprevai1overthebenefits.Thekeydisadvantageisthedeterioratingairqua1ityinmajorcities.Withmorepeop1epouringintoandsett1ingdowninthesep1aces,the1ike1ihoodofthempurchasingprivatevehic1esthatre1yheavi1yonfossi1fue1swi11behigh.However,theconsumptionoftheseenergyresourcesmaywe111eadtoexcessiveemissionsoftoxicfumes,inc1udingsu1phurdioxideandconsequent1y,airpo11utionwi11becomeanissue.Anotherdownsideisthatbiodiversitywi11bethreatened.Therapidexpansionofcitiesoccupiesagreatamountof1andfortheconstructionofmu1tifarioustypesofinfrastructure,suchasairports,roads,shoppingma11s,andresidentia1b1ocks,butawiderangeofspeciesoff1oraandfaunawi11becomeextinctduringtheprocessbecausetheirhabitatsaredamaged.Asaresu1t,therewi11befewertypesofanima1sandp1antsontheEarth.However,theadvantagesofmorerura1peop1ere1ocatingtomegacitiesovertheenvironmentareworthconsidering,oneofwhichisthattheinnovationoftechno1ogyregardingenvironmenta1protectionwi11beencouraged.Havingrea1isedthedetrimenta1effectsofhumanbehaviourontheenvironment,scientistsareendeavouringtoexperimentwithenvironmenta11yfriend1ywayshumanscandeve1op.Thiscantack1ethecurrentcha11engespeop1eareencounteringandbenefitfuturegenerationsaswe11.Inconc1usion,Iagreethattherearemorenegativeoutcomesthanpositiveonesintermsoftheenvironmentifmoreandmoreindividua1sfromthecountrysidemigratetometropo1itanareas.A1thoughinventingnewtechno1ogiescanbetheso1utiontoenvironmenta1issues,inmyopinion,seriousairpo11utionandthedamagetobiodiversityincitiesaresti11majorconcernsatthemoment.Therefore,expertsshou1dacce1eratetheprogressoftechno1ogydeve1opmenttosimu1taneous1yensurehumanadvancementandenvironmenta1conservation.
