您好,我大体修改了一下你的作文,有一些具体的语法问题和句子表达问题没有给你改,因为这是很难在短时间提高的.我T的大作文是Good,这里给你一点经验.不要照着xdf的思路去写作文,因为那样会太套路,比如每段第一句是主旨句然后举例子啥的.你可以看一下OG里面给出的两片满分作文,都不是这么构思的.另外你要注意og里面的范文都是把题目的各个方面都点到了,论述详细,但是examples并不是写的很多,很多是一句话带过了,更多的是抽象的论述.把握这几点,托福作文也就没有什么太担心的. 　　我觉得你的作文应该在3.5-4分左右的样子.主要缺点是是论述不够详细,比如说书本里面的只是和实践中的如何不同,为什么实践中的更容易记住和掌握等等；语言我觉得有的时候你真的太过刻意用高级句式和词汇了,真正好的句子并不是特别复杂的,而是准确的而且让人看懂的.很多地方你用了很多倒装句我觉得并不是很有必要,让人读起来感觉怪怪的. 　　作文还有小作文的部分,我觉得小作文是更好拿分的,因为有一些套路.小作文其实基本不用写阅读部分里面的内容,要把主力放到听力段子中,og上的范文你可以看一看.希望对你有帮助! 　　修改部分如下：（括号里是修改的） 　　Weliveinaworldwherealmostalltheknowledgecanbeobtainedfrombooks.(应为句号,therefore是副词,不能引导两个句子)Thereforealargeamountofpeoplebelievethatknowledgecontainedin(from)booksare(is)themostcrucial.However,isitawiseidea?Isthatmean(Doesitmeanthat)wecanignoretheknowledgegainedfromexperience?Ofcoursenot. 　　Nodoubtthatitisbooksthathaveahugenumberofknowledgeaboutvariousaspects,suchashistory,science,decoration,evencosmetology.（Nodoubtthatbookscontainknowledgeonallaspects,e.g.history,science,decoration,evencosmetology.）Itseemsthateveryonecan(will)benefitbykindsofspecializedbooks.Onlyabook,canprovidestudentslikememethodsofsolutionstosomemathproblems,cantellhousewiveshowtoprepareadeliciousmeal,canteachthepeasantryskillsofcultivation.Besides,itisquiteconvenienttogetabooknowadays(itisquiteeasytogetabookyouneededwiththehelpofmoderninformationsystem).Whetherweborrowabookfromnearlibraryorbuyonefromabookshop,wecanalwaysfindwhatweneed.Andwiththedevelopmentofprinting,printedmattersbecamecheapersothateverybodycanaffordthem. 　　Ontheotherhand,knowledgeacquiredfromexperiencealsoplaysaimperativerole(andknowledgegainfromthiswaycanneverbereplacedbythatfrombooks).Suchkindofknowledgecanbeabsorbedbetterandunderstooddeeply(easier保持句子的对称)bypeople.Takememyselfasanexample,whenIlearnedanewexperimentofphysics,notuntilImadeitbymyselfcanIcomprehendit.Inhighschoolsofourcountry,whatwelackofisthisefficientwaytogainknowledgethroughexperience.Whatwealwaysdoistoreadlotsofthickbooksofeverysubject,whichoftenmakesstudyatediousthing.Maybeonewillarguethattheknowledgeacquiredfromexperienceisnotsoprecisesothatitwillmisleadustoadiversedirection.Wecannotdenyit,butisthatknowledgeincludedinbooksusuallydefinite?Inourmodernsociety,producersofbookssurelyknowthatpeopleneversuspecttheknowledgefromabookatall,sotheyincreaselyprinttheirproductstogetaprofitwithoutconsideringthequalitiesofthem.Thenexpertscouldsearchoutanumberofmistakesinthoseso-calledspecializedbooks.Consequently,weshouldhaveasenseofjudgmentratherthandependonbooksblindly. 　　Inaword,thesetwotypeofknowledgebothhavetheiradvantagesanddisadvantages,soweoughtnottoactuallysay(that)whichoneismoreimportant(thananother).Inmyopinion,themostessentialthingis(tomakefulluseofknowledgegainedfrombooksandexperienceandcombinethemefficiently)howtomakefulluseofthevalueofthetwosourcesandcombinethemefficiently.
