给你支招 　　建议信是写信人向收信人对某事提出自己的建议或忠告，有可能是写给个人，就其遇到的某个问题提出自己的看法和观点；也可能是写给某个组织和机构，就改进其服务提出建议或忠告。建议信不同于投诉信，所以写信人一定要注意礼貌当先。建议信和普通的信件一样，通常由六部分构成：信头、信内地址、称呼、正文、结束语和签名。建议信要写出写信的原因，建议的 内容 财务内部控制制度的内容财务内部控制制度的内容人员招聘与配置的内容项目成本控制的内容消防安全演练内容 ，提出建议的理由和根据。理由要合情合理，语气一定要礼貌。因此建议信要写得简明扼要、目的明确、具有合理性和说服力。建议信一般采取“三段式结构”。首段：针对对方对自己的信任简单表示感谢，亦可表明自己的诚意。建议信的开头必须指明建议的前提和事情的原委，对自己的立场作一些解释。中段：围绕问题，结构清晰、科学婉转地提出建议。注意充分考虑对方的实际情况，表达时应选择得体用语。切忌用语生硬强制，泛泛而谈。通常以firstly，secondly，thirdly或tobeginwith，then，later等依次陈述建议。尾段：简单予以希望。希望自己的建议能对对方有所帮助。通常在建议信的结尾部分阐明你所提供的劝告或建议仅供对方参考，常用表达有：Ihopeyouwilltakemyadviceintoaccount./Ihopeyouwillfindtheseproposals/suggestions/recommendationspractical/useful/helpful。

　　目前，你们学校图书馆的服务存在一些问题。假如你是李明(高三五班的一名学生)，请你给你们的校长写一封信，提出一些有利于图书馆管理的合理化建议。内容如下：1.图书馆电脑的大部分键盘都有操作上的问题，给学生带来很多不便，建议更换新的键盘；2.建议图书馆购买更多新书，定购更多学术期刊；3.自习教室的照明系统也需要进一步的改进。注意：1.词数：100左右；2.不要逐条翻译，可以适当增加细节。参考词汇：subscribeto定购DearSir，I’mwritingtotellyousomesuggestionsonhowtoimproveourlibrary.Firstly，Ifindthatmostcomputerkeyboardsinthelibraryarebad(用词不贴切，最好为poor).It(将它改为which且把其前的句号改为逗号，即前后两句整合成一个复合句)causesmany(inconvenience是不可数名词，其前应用much)inconveniencetousers.Isuggestthatthelibrarywill(suggest后的从句谓语动词用should＋动词原形)buysomenewkeyboards.Secondly，ourlibraryhadbetterto(hadbetter后应接动词原形，故去掉to)buymorenewbooksandsubscribetomoreacademicjournalstoletthestudentsgetmoreandmoreinformations(information是不可数名词，故去掉s)intheirstudy.Lastbutnotleast，thelightsinthestudyroomarenotbright.Inordertoprotectoureyes，weneed∧(此处应添加a)betterlightingsystem.Surely，we’llbenefitalotof(alotof后没宾语，故去掉of).Theseareonlymypersonalsuggestions，∧(前后两个句子缺少连词but)Ihopetheycouldbetakenintoconsideration.Bestregards.Yourssincerely，LiMing

以我之见 　　1.本文注意了建议信的逻辑顺序和语言特点。文章中使用了一些过渡词：meanwhile，inthefirstplace,so，secondly，lastbutnotleast等。在语言上，语气中肯、委婉，符合建议信的特点。如：①Ifeelthatitwouldbebeneficialto...；②Theseareonlymypersonalsuggestions，butIhopetheycouldbetakenintoconsideration.等。2.用了一些高级词汇(短语)，如：beneficial有益的；taketheopportunityto利用这个机会；befurnishedwith安装有……的。【趁热打铁】假设你是谢凯，是一名中学生，你们学校附近有一条河，去年河边开办了一家工厂，河水受到污染。请你向厂长写一封120～150词的信，信中包含以下内容：1.建厂前河流的概况；2.工厂倾倒废水造成的后果；3.呼吁采取措施，保护环境。【参考范文】DearSir，MynameisXieKai.Youknow，thereisarivernearyourfactory.Itwasabeautifulriverwithcleanwater.Manylovelyfisheswereswimminginit.Therewereflowersandgrassonit’sbothbanks.Butwecan’tseeitnow.Sinceyourfactoryopened，ithasbecomedirtyandsmellsterrible.Thefishesdiebecausetheriverisseriouslypollutedbythewastewater.Theenvironmentisbecomingworseandworsebecauseofthepollutedriver.Wemustprotectourenvironment；wemustdosomethingfortheriver!Ithinkyoucanbuysomemachinestocleanthewastewater.Then，theriverwillbecleanagain.Allthepeoplearoundyourfactorywillthankyouverymuch!Amiddleschoolstudent，XieKaiUnit2EnglisharoundtheworldPeriod1-2Warming-upandSpeaking1.Knowledge：MasterthewordsandphrasesandgetaviewoftheroadtomodernEnglish.2.Ability：Trainstudents’readingskill.3.Emotion：LetstudentsknowmoreaboutEnglishandinspirestudentstostudyEnglishhard.●教学重点Theunderstandingandcomprehensionofthepassage.●教学难点（1）Howtogettomastertheusefulwordsandexpressions.（2）Howtoimprovestudents’abilitytoreadanarticle.●教具准备cassetterecorder，somepiecesofslide●教学过程Step1GreetingsT：Goodmorning，boysandgirls!S：Goodmorning，teacher!Step2WarmingupT：Englishisawidelyusedlanguage.DoyouknowinwhichcountriesEnglishisspokenastheirnativelanguage？Sa：TheUS，theUK，Australia，Canada...T：（aslide：Nancy：Oh，thereyouare.Nowthen，didyouhaveagoodflight？Joe：Sure，weflewallthewaydirectfromSeattletoLondon.Nancy：You
