随着科技的发展，电脑在二十一世纪成了人们必要的用品。随之而来，网络与我们的生活息息相关，给现代人的生活、工作带来了无与伦比的方便。通过网络，我们能查寻有用的资料,了解时事动态等等.当你工作了很长时间后去玩电脑游戏，可以减缓你的精神压力，放松你的心情.并且，上网玩游戏也不完全是坏事，因为学生玩游戏可以锻炼手、脑的反应能力，满足学生娱乐需要。但是网络也有弊。长时间的看电脑,电脑发出的辐射对人体有很大的害处。眼睛长期处于紧张状态容易造成近视。现在的电脑游戏众多,某些电脑游戏粗制滥造,甚至含有暴力等不健康内容。有的孩子由于对社会认识不足和自我保护意识缺乏，沉迷网络游戏，网络交友。其实网络并不可怕，只要我们面对网络时多一些认识，网络就会成为我们学习上的有利助手。让我们一起创个干净的网络世界吧！Withthedevelopmentofthescienceandtechnology,thecomputerhasbeenbecoingthenecessityforpeopleinthe21stCentury.Following,networkisofcloselinkwithourlife,bringingusincomparableconvenienceonourlifeandwork.Throughthenetwork,wecansearchforusefuldatasandgettoknowthecurrentevents.Whenyouplaycomputergamesafteralong-timework,itcanrelieveyourpressureandmakeyoufeelrelaxed.Besides,playingonlinegamesisnotallbad,foritcanfulfilstudents'entertainingrequestsaswellaspractisetheirresponseability.However,therestillexistssomedisadvantagesinthenetwork.Theradiationfromthecomputerwilldoharmtopeople'shealthifyoukeeponwatchingthecomputerforalongtime.Andshortsightmaycausedbyitforyoureyesstaytense.Atpresent,therearetoomanygamesontheInternet,butsomeofthemarenotofgoodqualityevencontainsomeunhealthycontentlikeviolenceandsoon.Duotothelackofrecognizingsocietyandself-protectionawareness,somestudentsgetaddictedinthegamesandonlinedating.Infact,networkisnotthathorrible,aslongasweknowmoreaboutit,itwillbecomeourrighthandonourstudies.Let'sbuildacleannetworkworldtogether.1)网络课堂教学的兴起，使传统的课堂教学受到了前所未有的挑战2)网络课堂教学模式会完全取代传统课堂教学模式吗？3)你的看法，理由是……【思路点拨】本题属于提纲式文字命题。提纲第1点指出一种新兴事物，提纲第2点针对该事物提出一个有争议的观点，提纲第3点要求表明“我”的看法，由此可判断本文应为对比选择型作文。根据所给提纲，本文应包含如下内容：描述网络课堂对传统课堂的挑战；提出关于网络课堂是否会取代传统课堂的两种不同观点并说明理由；表明“我”的态度并说明理由。【参考范文】WillNetworkClassroomsReplaceTraditionalClassrooms?WiththepopularizationoftheInternet,networkclassroomsaregainingmoreandmorepopularity.Asanewteachingpattern,networkclassroomshavebecomeaneffectivecomplementtotraditionalclassrooms.Sosomepeopleproposeonequestion:willnetworkclassroomsreplacetraditionalclassrooms?Astothisquestion,theopinionsvaryfromonetoanother.Somepeoplethinkitquitepossiblefornetworkclassroomstotaketheplaceoftraditionalclassrooms.First,networkclassroomsneedn’thaveface-to-facecommunicationandarenotlimitedbytimeandplace,whichfacilitatebothteachersandstudents.Secondly,networkclassroomsreleaseteachersfromrepeatingthesamecontentssincethevideooraudiomaterialcanbeplayedtimeandagain.However,manypeoplehaveoppositestandpoints.Theysaythatwithonlinecourses,studentslackdirectcommunicationswithteachersandtheirconfusioncannotbesolvedinstantly.Inaddition,thecomputersystemcannotbeguaranteedtoworkstablyallthetime。Personally,bothnetworkclassroomsandtraditionalclassroomsarenecessaryforstudents.Iftraditionalteachingpatternsandthemodernoneslikenetworkclassroomscanbecombinedtogether,morefruitfuleducationissuretoberealized。远程教育DistanceEducation在这个科技高速发展的信息时代，人们的购物、交流，甚至是学习等一系列生活所需都可以通过网络来完成。就此，我们分析下当今社会发展所流行的远程教育。Inthistechnicalhighspeeddevelopmentinformationage,people'sshopping,exchange,evenisstudiesandsoonaseriesoflivestobepossibletocompletethroughthenetwork.Underthis,weanalyzethedistanceeducationwhichthesocialdevelopmentispopularnow.首先，远程教育使偏远地区的人们学习他们感兴趣的项目成为可能。Foronething,distanceeducationmakesitpossibleforpeopleinremoteareastolearnthesubjectstheyareinterestedin.另外，人们有更广的范围选择老师和课程，因为他们可以听全国甚至全世界最好的老师讲的最好的课程。Foranother,peoplehaveawiderrangeofchoicesastoteachersandlessons,becausetheycanlistentothebestlessonsbythebestteachersinthecountry,orevenintheworld.但是，弊端也是有的。由于老师与学生间交流不生动，因此学术探讨也不够深。But，malpracticeisalsosome。Becausebetweenteacherandthestudents’exchangesnotvividly,thereforeacademicdiscussionalsoinsufficientdepth.总之，远程教育发展空间很大，教育前景很好，只是需要时间逐步完善。Inbrief,thedistancelearningdevelopmentopportunitiesareverybig,theeducationprospectisverygood,isonlyrequiresthetimetoconsummategradually.Beingonlineisnolongersomethingneworfreshinourlife.Tosomeextent,ithasbecomepartofourdailylife.Wecandoalotofthingsonline,suchassearchingforinformationandcommunicatingwithfriendsfaraway.Butrecentlyanotherhelpfulonlineactivityhasbecomevery“in”.Thatisonlineeducation.Whycouldonlineeducationbesopopularwithinsuchashortperiodoftime?Amongotherreasons,thequickdevelopmentoftheInternetshouldbeanessentialone,whichmakesallourdreamsofattendingclassinthedistancepossible.Anotherunderlyingreasonisthequickdevelopmentofbothsocietyandtechnology.Today,modernscienceandtechnologyisdevelopingwithfantasticspeed.Tocatchupwiththisdevelopmentweallfeelanurgentandstrongdesiretostudy.However,duetothegreatpaceofmodernsociety,manypeoplearetoobusytostudyfulltimeatschool.Onlineeducationjustcomestotheiraid.examda.comPersonally,Iappreciatethisnewformofeducation.It’sindeedahelpfulcomplementtothetraditionaleducationalmeans.Itcanprovidedifferentlearnerswithmoreflexibleandversatilewaysoflearning.Bestofall,withonlineeducation,wecansticktoourjobsandatthesametimestudyandabsorbthelatestknowledge.点评：英特网的迅速发展改变了人们的生活和学习、工作方式，现代生活节奏快、工作忙导致人们没时间全日制的学习，网络和远程教育正好满足了人们的学习需要，许多大学生利用因特网学习知识，它成为传统教学的有益补充。本预测题贴近时代，也与大学生校园生活相关，值得重视。Withtherapiddevelopmentofscienceandtechnology,tele-educationhasspedupinou
