定景描写(景观不变，更换视察角度)的手法。处理好空间位置的转化。4．突出语言特色：以描写为主要写作手法，对景物进行介绍，并适当抒发个人感情。为此在写作中要依据内容提示，筛选可能用到的描述该景点的形容词，既要恰当、敏捷地运用词汇，又要避开同一词汇的重复运用。5．抓住典型特征：在描写中要做到重点突出，详略得当。可以把景点和四周环境及景点的历史意义等结合起来。6．把握文章时态：文章的时态通常采纳一般现在时，用于强调客观事实。【常用句式】①...liein/on/totheeast/west/north/southof...②Locatedin...，...coversanareaof...③Situatedin...，...isparadisefor...④...islocated/situatedin/to/on...，coveringanareaof...⑤...hasbecomethemostpopulartouristattractionfor...⑥...beknown/famousfor/as...⑦Ithasapopulationof...，withahistoryof...⑧Theweatherheregetsneithertoocoldnortoohotalltheyeararound.⑨Ifyoucometo...foravisit，youwillhaveachancetoenjoy...⑩Atripto...willgiveyouaglimpseofthehappylifestyleof...⑪...，knownas...，attractsvisitorsfromallovertheworld.⑫Awalkaround...isafeastforyoureyes.假设你是晨光中学高二(1)班的班长李津，得知美国学生Chris作为交换生，下学期将到你班学习。请你依据以下提示，给他写封邮件。1．表示欢迎；2．介绍与本地生活相关的信息(如气候、饮食等)；3．介绍本班状况；4．希望Chris做哪些事情，以增进中美学生间的了解和友情。留意：1.请勿提及与考生相关的真实信息；2.可以适当增加细微环节，使内容充溢、行文连贯；3．词数80左右；开头已给出，不计入总词数。参考词汇：交换生exchangestudentDearChris，I'mLiJin，monitorofClassOne，GradeTwo.___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________Yours，LiJin【范文点评】范文点评DearChris，I'mLiJin，monitorofClassOne，GradeTwo.Knowingthatyouwillstudyinourclassasanexchangestudentnextsemester，①weallfeelexcitedandeagertomeetyou.Generallyspeaking，②theclimatehereispleasant.Butinwinteritcanbeabitcold,soyou'dbettercarrysomeovercoats.Asiswellknown，③theChinesefoodisdelicious，I'mconfidentyouwilladoreit.Ourclass,consistingoftwentygirlsandthirtyboys，④isahappygroup.Don'thesitatetoaskusforhelp.Besides，IhopeyoushowusAmericanschoolsandculture，andmeanwhileconveyourculturetoyourclassmates.We'relookingforwardtoseeingyou.Yours，LiJin本篇习作语言地道，覆盖了全部要点，并且适当增加了细微环节，使内容充溢、行文连贯。本文同时运用了较多的高级句式结构，另外还多处正确运用了非谓语动词。①非谓语动词作时间状语，表示与句子主语动作同时或几乎同时进行。此处表达一听到Chris要来，全班同学都激烈的那种心情。②这是评注性短语，常放在句首作状语，也可以换成generally或ingeneral。同时在此处也起到过渡作用。③处as引导非限制性定语从句，as代指整句话内容。④非谓语动词consistingof作后置定语运用。另外，consistof用得特别精确，须要提示的是这个短语不能运用被动语态写一篇介绍华山的短文，80词左右。要点如下：1．华山位于陕西省华阴市，是我国闻名的五岳(FiveSacredMountains)之一；2．华山有五座山峰(peak)，分别为东峰、西峰、南峰、北峰和中峰；3．可以步行上山，也可乘索道(ropeway)或缆车(cablecar)。___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________答案：MountHuaMountHuaislocatedinHuayin，ShannxiProvince.ItisfamousasoneoftheFiveSacredMountainsofChina.ItsfivemainpeaksaretheEastPeak，theWestPeak，theSouthPeak，theNorthPeakandtheMiddlePeak.Youcanclimbtothetoponfoot，takingtheropeway，orridinginacablecar，whereyoucanenjoythescenery.You'llseeanumberofstrangehillsanduniquerocks.Whenyouarriveatthetop，youcanlookoutoveraseaofclouds.Nowitisattractingmoreandmorepeople.Whynotpayavisithere？A级基础过关Ⅰ.用所给单词的正确形式填空1．Shewasfoundalivebut________(conscious)．2．I'm________(anxiously)abouthersafety.3．Toshowour________(appreciate)forallyourhardwork，we'dliketogiveyouabonus.4．Peopleliketolivealifefullof________(various)．5．Istoodthere________(tremble)withanger.6．Thecompanyguaranteed________(deliver)myorderwithintwodays，whichmademesatisfied.7．Thelabsinourschoolare________withalotofgood________，whichishelpfulforourstudy.(equip)8．She________herdressasfashionchangesforshehas________kindsofclothesandshoesandshethinksthat________isthespice(调味品)oflife.(vary)答案：1.unconscious2.anxious3.appreciation4．variety5.trembling6.todeliver7.equippedequipment8．variesvariousvarietyⅡ.选词填空burntotheground;haveagiftfor;makeone'swayto;glancethrough;makeup;outoftheway；inthedistance;pickup;behometo;givebirthto1．Nowadaysmanyyoungcoupleshavevolunteeredto____________________onlyonechild.2．Women______________________over65percentoftheworkforceinthatcountry.3．Hearingthebellringing,theladyrosefromherchairand____________________thedoor.4．She_________________makingeveryvisitorfeelatease.5．Hecarelessly________________________thenoticeonthebulletinboardandgotaway.6．Iclimbedthehillandsawafaintlightcomingfromahouse____________________．7．Thebigfirespreadacrossthestreetquicklyandbuildingsonbothsides____________________．8．Shesaidshe______________________someJapanesewhileshewasinJapanforavisit.9．Zhongguancun________theChineseAcademyofSciencesandmorethantenfamousuniversities.10．Makesurethekidskeep________whileI'mworking.答案：1.givebirthto2.makeup3.madeherwayto4.hasagiftfor5.glancedthrough6.inthedistance7．wereburnedtotheground8.pickedup9.ishometo10.outofthewayⅢ.依据汉语完成句子1．She______________whenshethoughtshe'dlostthetickets.她特别惊惶，以为自己把入场券丢了。2．Iwokeup___________
