高二英语Savingtheearth教案

RSEFC2AUnit9Savingtheearth
教材分析
本单元的中心话题为“拯救地球”，通过课堂导入引出水污染、空气污染、环境破坏，乱砍乱伐树木等环境问题，围绕这一主题，结合听、说、读、写的训练达到熟悉话题表述，语言熟练应用，能运用所学知识就环境问题展开讨论，在口头上和笔头上阐述自己的观点，达到语言输出的目的。
“热身”（Warmingup）部分，运用图片导入法，通过对所展示图片的讨论，引出环境保护、拯救地球的主题，初步了解学生对现状、原因、解决办法的掌握程度，并通过提问了解学生对本单元学习内容、学习策略、学习途径的愿望，以便教师及时调整其后课堂教学的内容、难度、和深度的把握。
“听力”训练由两大部分组成，分别安排在“听力”（Listening）和“综合技能”（IntegratingSkills）两个部分。前者又由两部分组成，第一部分为纪念“世界地球日”活动上的讲话，阐述了保护水资源的必要性和紧迫性。第二部分围绕保护水资源的主题，介绍了如何保护水资源的具体措施；后者，作为综合语言运用部分，听力内容主要为其后的写作作为铺垫，除了敏锐捕捉语言信息以外，学生还需要了解发言稿的开篇、论证、以及结束。
“阅读”（Reading）着重介绍世界地球峰会的由来，详细描述了2002年南非约翰内斯堡地球峰会的召开情况，展示了“可持续发展”这一主题，会上大多数代表所涉及的“世界三大杀手（被污染了的饮用水、简陋的卫生设备和空气污染，以及贫困、战争、和暴乱，指出世界的顺利发展，取决于各国的和平相处、互相合作、互相促进、共同进步，最后文章还阐述了世界地球峰会的作用和意义。
“语言学习”（LanguageStudy）要求学生利用构词法的知识，灵活运用词形变化进行正确运用，在第二部分要求学生正确辨别－ly结尾词的词性。
“语法”（Grammar）通过对倒装形式的总结，全面了解倒装的具体结构和应用，结合句型转换和选词填空练习，帮助学生掌握这一语法现象。
“综合技能”（Integratingskills）采用高一课本中未曾出现过的展示方式，选用听力方式展示写作模式，通过口头讨论等方式，巩固学生对本单元知识的掌握，从而有效地指导学生进行写作练习，并通过Unit2中的checklist对所写的书面表达进行修改。

II.补充语法
倒装语序分为“全部倒装”和“部分倒装”。在全部倒装的句子中，整个谓语都放在主语的前面；在部分倒装的句子中，只是谓语中的一部分（如助动词、情态动词或系动词be等）放在主语前面，其余部分仍放在主语后面。一、由there,here或now等引起，谓语为come（或go）的句子，例如：
Therecomesthebus!Theregoesthebell!
HerecomesMary!Nowcomesyourturn.
注：如果主语为人称代词，仍用自然语序，例如：
Therehecomes!Hereshecomes!

二、由then引起，谓语为come（或follow）的句子，
Thencameanewdifficulty.
ThenfollowedeightyearsoftheAnti-JapaneseWar.

三、由here（或there）引导，谓语为be的句子
HereisChina’slargesttropicalforest.
Herearesomepicture-books.
注：如果主语为人称代词，仍用自然语序，
Hereyouare./Hereweare./Hereitis

四、由so引起的，表示前面所说的情况也适用于另一个人（或物）的句子，如：
Societyhaschangedandsohavethepeopleinit.
Heplaystheviolinquitewell.Sodoesmysister.
如果一个句子只是重复前面一句话的意思，尽管so用开头，语序也不要倒装
--Itwascoldyesterday.–-Soitwas!

五、由neither或nor引起的，表示前面所说的情况也适用于另一个人（或物）的句子，
--Iwon’tdosuchathing.
–-Neither/NorwillI.
--Ihaven’tdonemyhomework.
–-Neither/NorhaveI.
Ifyoudon’tgo,neitherwillI.
Ididn’treadthenotice,nordidhe.

六、在if引导的非真实条件句中，如有助动词had,should或were时，可以省略if，进行倒装，
HadIcomefiveminutesearlier,Iwouldhavemetthefamousscientist.
(IfIhadcomefiveminutes…)
Shouldanyonecall,tellhimtowaitformehere.
WereItenyearsyounger,Iwouldwithyou.
Shouldyouchangeyourmind,letusknow.

七、out,in,up,down,away等副词放在主语前,主谓倒装
Upflewtheredballoon.
Outrushedapolicemanfromamongthecrowd.
注：如果主语是一个人称代词，谓语仍放在后面，如：
Awaytheywent./Downitflew./Upitwent.八、当as引导让步状语从句时，把表语提到前面来,用“形容词（或副词、名词+as+主语+谓语”这种形式
Childasheis,heknowsalot.
Tiredashewas,hecontinuedtowork.
HardasIwork,Ican’tcatchupwithyou.
Muchasweliketheplace,wecan’tstayhere.
九、当always,often,manyatime等词放在句首时，后面常用倒装语序，如：
Alwaysdidhecometohelpus.
Oftendidwewarnthemnottodoso.
Manyatimedidhegoswimmingintheriver.
注：上述所说的词不放在句首，不用倒装语序。
十、only所修饰的副词、介词短语或状语从句放在句首时，其后面的主语部分要进行倒装，如：
Onlyinthiswaycanyouhopetoimprovethesituationthere.
OnlythendidIrealizethatIwaswrong.
Onlyoncedidhisfatherdiscusshisfuturewithhim.
OnlyyesterdaydidIrealizewhatwasgoingon.
OnlyafterhecamebackwasIabletoseehim.
注：only修饰主语，仍用自然语序，如：
OnlysocialismcansaveChina.十一、含有否定意义的副词、连词或短语构成的状语放在句首时，常用倒装语序
not,never,hardly,seldom,little,rarely,
scarcely,notuntil,notonly…butalso…,
neither…nor…nosooner…than…,
hardly…when…,scarcely…when
NevershallIforgettheday.
NotuntilIbegantoworkdidIrealizeIhadwastedmuchtime.
Notonlydidhereadthebook,butalsoherememberedwhathehadread.
Nosoonerhadhearrivedthanhefellill.
Hardly/Scarcelyhadhearrivedwhenhefellill.
注：上面所说的词和词组如果不在句首，句子不必用倒装语序。
另外，notonly…butalso连接两个主语时,不用倒装，如：
Notonlythestudents,butalsotheteacherwishesforaholiday.
十二、当so（或such）…that…结构中的so或such用于句首时，要采取倒装语序，如：
Soloudlydidhespeakthathewasheardupstairs.
Soangrywashethathecouldn’tspeak.
Soharddoeshestudythatheisthebestintheclass.
Suchwastheforceoftheexplosionthatallthewindowswerebroken.
Suchwashisstrengththathecouldbendironbars.
注：such和be连用作表语时，也常用倒装语序，
Suchwastheresult.
Suchwereherwords.
Suchwasthestoryhetold.十三、在下列结构中也常用倒装语序：
Infrontofthemstoodagreatcastle.
Onthebedlayasickoldman.
Underthetreesatanoldman.
Seatedonthegroundaresomeyoungmen.
Lyingonthefloorwasaboy.

典型例题：
1.NotuntilIbegantowork______howmuchtimeIhadwasted.　
A.didntIrealizeB.didIrealize
C.Ididntrealize　D.Irealize
2.—DoyouknowTomboughtanewcar?
—Idontknow,_______.
A.nordontIcare　B.nordoIcare
C.Idontcareneither　D.Idontcarealso
答案为B。Notuntil引导从句位于句首，后面的主句要倒装。
答案为B。句中的nor引出部分倒装结构，表示"也不"。由so,neither,nor引导的倒装句，表示前一情况的重复出现。其中,so用于肯定句,而neither,nor用在否定句中。典型例题
—WhycantIsmokehere?
—Atnotime_______inthemeeting-room.
A.issmokingpermittedB.smokingispermitted
C.smokingisitpermitted　D.doessmokingpermit
答案A.这是一个倒装问题。当否定词语置于句首以表示强调时，其句中的主谓须用倒装结构。这些否定词包括no,little,hardly,seldom,never,notonly,notuntil等。本题的正常语序是Smokingispermittedinthemeeting-roomatnotime.
Notuntiltheearlyyearsofthe19thcentury_______whatheatis.
A.mandidknow　B.manknow　
C.didntmanknow　D.didmanknow
答案D.看到Notuntil…的句型，我们知道为一倒装句，答案在C，D中选一个。改写为正常语序为，Mandidnotknowwhatheatisuntiltheearlyyearsofthe19th.现在将not提前，后面就不能再用否定了,否则意思就变了。典型例题
Nosooner_______thanitbegantorainheavily.
A.thegamebegan　B.hasthegamebegun
C.didthegamebegin　D.hadthegamebegun答案D.以具有否定意义的副词放在句首时，一般采用倒装句(谓语前置)。这类表示否定意义的词有never,seldom,scarcely,little,few,not,hardly,以及notonly…but(also),nosooner…than,hardly…whenscarcely…when等等。
注意：只有当Notonly…butalso连接两个分句时，才在第一个分句用倒装结构。如果置于句首的Notonly…butalso仅连接两个并列词语，不可用倒装结构。
NotonlyyoubutalsoIamfondofmusic.
