Newwordsandexpressions1.学生能够了解本单元单词的基本用法。2.学生能够辨析易混淆词的用法,并能熟练运用。3.学生能够掌握重点难点词的拓展及其用法。4.学生能够用所学单词翻译或造出句子,提升自己的句子表达和写作水平。本节课为unit4的单词和短语教学,单词本来是零散的,易混的,但是本节课运用了从点到线,从线到面的词汇教学方法,使重点难点单词成了容易掌握的单词块,单词串,从而实现了知识即词汇的重新组合,这一点也符合新的英语教学大纲的要求。首先,用听本单元的单词录音进行导入,让学生从整体上感知下单词。然后,对重点单词进行讲解,既有对单词用法的拓展,又有对短语释义的延伸。讲解和巩固练习结合,让学生加深理解词汇用法并当堂掌握。Wordsandexpressions1.theotherday不久前一天alldaylong=allday整天,终日,一天到晚dogdays三伏天,闷热天everyotherday每隔一天,每两天haveadayoff休假一天oneday/someday有一天,某一天,总有一天dayafterday一天又一天地,日复一日地dayandnight日日夜夜地daybyday逐日地,一天天地2.relevant(adj)→relevantly(adv)“有关的,有实际价值(重要性)的”反义词:irrelevant这种工作与经验无关。Theworkofthiskindisnotrelevanttoexperience.这类课程与当今的社会问题的关系而论已毫无实际价值。Thetypeofthecourseisnolongerrelevanttotoday’ssocialproblem.berelevantto=havesth.todowith与……有关relevancen.关联;相关性haverelevanceto与……有关havenorelevanceto=havenothingtodowith与……无关Topicsforcompositionsshouldbe_____totheexperiencesandinterestsofthestudents.A.concernedB.DependentC.concerningD.relevant【解析】选D。句意为:作文的题目应与学生的经历和兴趣有关。berelevantto与……有关。而concerning是介词,相当于about,后面不加to。D3.remotearemoterelative远亲aquestionremotefromthesubject与本主题不相干的问题beremoteandcoldinone’smanner态度冷淡aremotepossibility极小的可能性4.adjust小屋内很黑,因此,眼睛要过好一阵才能适应过来。▲adjustvt&vi.调整;(使)适合adjusttosth./doingsth.适应(做)某事adjustoneselftosth.使某人(自己)适应某事adjustableadj.可调整的;可调节的adjustmentn.调整;调解;(思想、行为的)调整,适应makeadjustmentsto对……作出调整5.participatevi.参加参与1)participateinsth.a.他没有参加讨论。Hedidn’tparticipateinthediscussion.b.Adultsdeveloptheconfidencetoparticipateinthesocial,economicandpoliticallivesoftheircommunities.成年人在他们的社会生活中增强参与社会、经济和政治的自信心。c.希望全班同学参与这项活动。Allthestudents__________areexpectedto___________intheactivity.inourclassparticipate2)participationn.参加参与Thisisashowwithlotsofaudienceparticipation.这是一次观众热烈参与的演出。3)compare“参加”:participatein,attend,join,takepartin与joinin?①participatein正式用语,表参加,参与。强调与他人共同参加某一活动,暗示以一种积极的态度参加。②attend正式用语,一般用于指参加会议,出席典礼或招待会等,也可以指上学,听课,听演讲或讲座等。③join常用词,作及物动词;通常指参加某组织或团体,并成为其中的一员,其宾语往往是thearmy/party/team/club或sb.等。④takepartin指参加群众性的活动,侧重说明主语参加该项活动并在其中发挥一定的作用。part前若有修饰语,要用不定冠词。如take(anactive)partinschool/activities。⑤joinin参加正在进行的活动,其宾语一般是竞赛、娱乐、谈话、讨论、聚会、游戏等名词,可以用于joinin(doing)sth./joinsb.in(doing)sth.结构中。选用所给单词或短语的适当形式填空join;joinin;takepartin;attend;participatein①Theyall______________theplot.②Attheageofeight,he________agroupofchilddancers.③Thechildren___________theEnglishEveningandhadagoodtime.④Hedidn’t________schoolyesterdaybecauseofhisillness.⑤ZhouEnlai___________thestudentmovementsactivelywhenhewasatschool.participatedinjoinedjoinedinattendtookpartinHetoldmethatthecanwasheatedto__________________(2)Watertheplantregularly,neverletting________________(让土壤干枯)6.dryout(使)变干;干透(1)他告诉我加热罐子是为了使剩余的食物变干。dryouttheleftoverfood.thesoildryout7.dryup(河流,湖泊等)干枯;弄干、晒干、变干;(供应、思路)枯竭(1)Duringthedrought,theriverdriedup.(2)Thewriter’slongseparationfromsocialdrieduphisimagination.(3)太阳很快就会把马路晒干的。___________________________Thesunwillsoondryuptheroads.8.otherwise(adv.&conj.)“用别的方法,其他方面;否则,不然(or)”Heisslow,butotherwiseheisagoodworker.Seizethechance,otherwise(or)youwillregretit.★祈使句,and(or,otherwise)+简单句(简单句常用将来时)1)Hurryup,________youwillbelate.A.andB.otherwiseC.ifD.unless2)Studyhard,_______youwillpasstheexam.A.andB.orC.ifD.unless3)Studyhard,______youwillnotpasstheexam.A.andB.otherwiseC.ifD.unlessBAB9.donatedonatev.捐赠,赠送donatesth.tosb.向某物捐赠某人donationn.捐赠;捐赠物;捐款donatorn.捐赠者make/give/presentadonationtosb.捐赠给某人sendadonationto把捐款寄至……promiseadonation应允捐赠①He_____________________(捐赠)amilliontotheschool.②Therestofthemoneywegetis______________(来自捐赠)madeadonationoffromdonations10.inneed在困难中,在危急中句意理解:Afriendinneedisafriendindeed.患难朋友才是真朋友.(1)我们应该帮助有困难的人.Weshouldhelpthoseinneed.(2)他现在很需要一大笔钱.Henowisingreatneedofmuchmoney.11.purchase1)vt.购买采购;努力取得a.他把两年前买的那幢房子卖了。Hesoldthehousehehadpurchasedtwoyearsbefore.b.Theypurchasedlifeattheexpenseofhonour.他们以牺牲名誉为代价换得了生命。2)n.购买购得物如果你对所购之物不满意,我们将全额退款。Ifyouarenotsatisfiedwithyourpurchase,we’llgiveyouafullrefund.返回makeapurchase买东西returnone’spurchase退货agoodpurchase便宜货acquiresthbypurchase买得某物提示:purchase要比buy正式12.securityn.安全保障1)theSecurityCouncil(联合国)安全理事会2)出于安全的考虑须对旅客进行搜身。For_______reasonsthepassengershaveto_____________.securitybesearched返回13.operate(vt&vi)vi工作,运转,动手术(on)Somepeoplecanonlyoperatewellunderpressure.Thefamousdoctorhasoperatedonmanyimportantpeople.vt操作Whatskillsareneededtooperatethismachine.operationn.操纵,经营,手术operatorn.接线员,操作人员,手术员operateon给……动手术performanoperationon…给……实施手术Inoperation工作中,使用中,有效comeintooperation开始工作,开始有效putsthintooperation实施,启用使……运转★Shewillhaveto___________onforhercancer.★Heandtheotherdoctorsdidn’tleaveuntilthe__________wasover.★Hewillperformanoperation______herforadiseasedlung.beoperatedoperationon
