10．(2009年高考四川卷)—MayIopenthewindowtoletinsomefreshair?
—________
A．Comeon！B．Takecare!
C．Goahead!D．Holdon!
解析：选C。问句是在请求许可，句意是：我可以打开窗户，让新鲜空气进来吗？四个选项中只有Goahead！表示说话者同意，意为“打开吧！”Comeon！用来催促对方，意为“快点吧！”Takecare！小心！Holdon！坚持住！。

★11.(2009年高考安徽卷)—Couldyoubesokindastoclosethewindow?
—________.
A．Withpleasure　B．Goahead
C．Yes，pleaseD．That’sOK
解析：选A。问句的意思是“你可不可以好心把窗户关上？”这个情景是请对方做某事，所以回答不能用Goahead，而是Withpleasure(愿意)。
★12.(2010年高考重庆卷)—Honey，let’sgooutfordinner.
—________Idon’thavetocook.
A．Forgetit！B．That’sgreat!
C．Why?D．Goahead.
解析：选B。句意：——亲爱的，我们去外面吃晚饭吧。——太好了！我不必做饭了！由语境Idon’thavetocook可知，听话者非常赞同说话者提出的建议，故答案为B项。forgetit“没关系”“不必太在意”；why？“干嘛？”goahead“去做吧”，都不符合语境。

13．—Theplane________arriveat11∶30，butwasalmosthalfanhourlate.
—Commonpractice.
A．wasaboutto　B．waslikelyto
C．wassupposedtoD．wascertainto
解析：选C。besupposedtodo“本应该”。

★14.Themessageisveryimportant，soitissupposed________assoonaspossible.
A．tobesentB．tosend
C．beingsentD．sending
解析：选A。句意：这条信息很重要，所以要尽快发出去。besupposed后接不定式结构，意为“理应，应该”，排除C项和D项。it指message，message和send之间为被动关系，排除B项，故A为正确答案。
句型梳理
①　Itishardtothinkofaworldwithoutmetals.(P44)
很难想象一个没有金属的世界。
　本句中，it为形式主语，真正的主语是不定式短语tothinkof...，构成Itis/was＋adj.＋todosth.的结构。
Itis＋adj.＋forsb.todosth.该句式中，作表语的形容词只能说明不定式的行为性质和特点，不能说明不定式的执行者。常见的这类形容词有：easy，important，difficult，hard，possible，impossible，necessary等。
Itis＋adj.＋ofsb.todosth.该句式中，作表语的形容词表达不定式的逻辑主语的品行、性格或性质。常见的这类形容词有：kind，nice，good，honest，careful，careless，clever，wise，stupid，foolish，rude，polite，impolite等。
Itis＋adj./n.＋that?clause
Itis＋nogood/usedoingsth.
①Itiseasiertosaythantodo.说比做容易。
②Itisnogoodplayingcomputergames.玩电脑游戏没有好处。
③Itisashamethathedidn’tpasstheexam.
很遗憾他没有通过考试。
④Itissaidthattheticketshavebeensoldout.
据说票已售完。
15．(2010年高考大纲全国卷Ⅱ)Thedoctorthought______wouldbegoodforyoutohaveaholiday.
A．thisB．that
C．oneD．it
解析：选D。句意：医生认为度假对你有好处。本题考查代词it作形式主语。根据句意不定式短语tohaveaholiday在宾语从句中作真正的主语，只有it可作形式主语，故选D项。

★16.(2009年高考天津卷)Itisobvioustothestudents________theyshouldgetwellpreparedfortheirfuture.
A．asB．which
C．whetherD．that
解析：选D。句意是：对学生来说，很明显的是他们应该为将来做好准备。It是形式主语，________theyshouldgetwellpreparedfortheirfuture是主语从句，作真正的主语。这个引导词起引导作用，不作成分，故用that。
②　Hereisatablewiththemetalsthatreactmostatthetop，andthemetalsthatreactleastatthebottom.(P44)
这儿有一个图表，那些反应最强烈的金属在上部，反应最不强烈的在下部。
　这是一个倒装句，正常语序是：Atablewith...ishere.
(1)在there，here引导的句子中，谓语是be，exist等表示状态的不及物动词时，句子要全部倒装。
(2)在there，here，now，then，thus等开头的句子里，谓语动词是come，go，follow等时，句子要全部倒装。
(3)here，there引导的句子，当主语是代词时，不倒装，且此类句子不用进行时。
①HerearewhatIwantyoutodo.下面是我想让你做的事情。
②Theregoesthebus.公共汽车走了。
③Nowcomesmyturn.现在该轮到我了。
17．(2010年高考江苏卷)—Iseveryonehere?
—Notyet...Look，there________therestofourguests!
A．comeB．comes
C．iscomingD．arecoming
解析：选A。句意：——都到了吗？——还没有……看，其余的客人过来了！本题考查主谓一致。本句中there放在句首，句子采用了倒装句式，谓语动词应该根据句子的主语therestofourguests来判断，B项和C项为第三人称单数形式，可排除；come用于进行时态表示将来的动作，不合题意，可排除；A项谓语动词与主语一致，故答案为A。

★18.(2009年高考福建卷)Foramomentnothinghappened.Then________allshoutingtogether.
A．voiceshadcomeB．camevoices
C．voiceswouldcomeD．didvoicescome
解析：选B。考查倒装结构。表示时间的副词now，then及表示方位的副词here，there等位于句首，与位移性动词come，go，arrive等连用，且主语不是人称代词，此时用完全倒装。从前一句可知此处描述的是过去的事情，所以用一般过去时。

Answers：3forms——原级、比较级和最高级。
Step3.DetailedNotesaboutGrammarUsage
⒈原级的构成和用法
1）构成：形容词和副词的原级形式是形容词和副词的原形。
2）用法：当表示双方在程度、性质、特征等某方面相等时，用“as+原级adj./adv.+as”的结构；当表示双方不相等时，用“notas(so)+原级adj./adv.+as”的结构；当表示一方是另一方的若干倍时，用“倍数+as+原级adj./adv.+as”的结构。例如：
①HeisastallasJack.//IspeakEnglishasfluentlyasyou.
②Yourbikeisnotas(so)newashers.
③Thisroadisthreetimesaslongasthatone.
⒉比较级和最高级的构成和用法
1）构成：
⑴规则变化
①单音节形容词以及少数以－er,－or结尾的形容词和副词加＂er＂，＂est＂．例如：
fast-faster-fastest;few-fewer-fewest;great-greater-greatest;
clever-cleverer-cleverestnorrow-norrower-norrowest.
②以e结尾的单音节形容词和副词后以及少数以-ble,-ple结尾的双音节形容词和副词后，加＂r＂，＂st＂．例如：
large-larger-largest,able-abler-ablest,simple-simpler-simplest
③以一个辅音结尾的单音节形容词，其前面的元音字母发短元音时，该辅音字母要双写，然后加＂er＂，＂est＂．例如：
hot-hotter-hottest
④以辅音加y结尾的形容词和少数不是形容词加ly构成的副词要将y改写为i，再加＂er＂，＂est＂．例如：
easy-easier-easiest,happy-happier-happiestearly-earlier-earliest
⑤一般双音节词、多音节形容词和副词在原级前more或most．例如：
beautiful-morebeautiful-mostbeautiful;carefully-morecarefully-mostcarefully
⑥少数单音节或双音节形容词也加more和most构成比较级和最高级。例如：
tired-moretired-mosttired;pleased-morepleased-mospleased;
crowded-morecrowded-mostcrowded
⑵不规则变化
原级比较级最高级
good,wellbetterbest
bad,illworseworst
many,muchmoremost
littlelessleast
oldolder(较老、较旧),
elder（较年长）oldest(最老、最旧)，
eldest(最年长)
farfarter(较远的),
further(进一步地)farest（最远的）
furthest（最深刻地）
[注意]辨析few-fewer-fewest和little-less-least的差别:①前者是规则变化，后者是不规则变化；②前者用来修饰可数名词，后者用来修饰不可数名词。
2）用法：
⑴比较级的用法
①双方比较，表示一方超过另一方时，用“比较级+than”的结构表示。例如：
Thisbookisbetterthanthatone.
②表示一方不及另一方时，用“less+原级adj./adv.+than”的结构表示。例如：
Thisroomislessbeautifulthanthatone.
③表示一个方面随另一个方面的程度而变化时，用“the+比较级（+主语+谓语），the+比较级（+主语+谓语）”的结构。例如：
Theharderheworks,thehappierhefeels.
Theharderyoustudy,themoreknowledgeyouwillget.
④表示自身程度的改变“越来越---”时，用“比较级+and+比较级”结构表示。如：
Theweatherisgettingcolderandcolder.
Thelittlegirlbecomesmoreandmorebeautiful.
⑤表示倍数的比较级有如下几种句型：
a)“倍数+as+原级adj.+as+被比较对象”，例如：
Thisriverisfourtimesaslongasthatone.（这条河是那条河的四倍长）
b)“倍数+the+size(length,width,depth,height)+of+被比较对象”，例如：
Thisriverisfourtimesthelengthofthatone.（这条河是那条河的四倍长）
c)“倍数+比较级adj.+than+被比较对象”，例如：
Thisriveristhreetimeslongerthanthatone.（这条河是那条河的四倍长/这条河比那条河长三倍）
[注意]：
在比较级的前面可以加上如下一些表示程度的状语，但要注意其含义的差别。
a)any加比较级,表示疑问程度，译为“------一些”，“------一点”。例如：
Areyoufeelinganybetter?
b)no/not(any)加比较级,表示否定程度，译为“并不-------”。例如：
Somegrownohigherthanyourankles.
Thisfilmisnotmoreinterestingthanthatone.
c)abit,alittle,slightly加比较级,表示“稍微，一点（些）”。例如：
MayIstayherealittlelonger?
Thisproblemisabitmoredifficultthanthatone.
d)many,much,alot,greatly,(by)far,rather,agood(great)deal等加比较级,表示“------得多”。例如：
Ourschoolismuchmorebeautifulthantheirs.
Thepeoplehereareagreatdealrichernowthanbefore.
[附]byfar通常用于强调最高级。用于比较级时，一般放在比较级的后面，如在前面，应在二者中间加“the”。例如：Heistallerbyfarthanhisbrother.//Heisbyfarthetallerofthetwobrothers.
e)even,still加比较级,表示强调，译为“甚至更/还要-------”。例如：
Hegetsevenstronger.
Jackistall,butTomisstilltaller.
f)“数词+名词+比较级”表示确定的程度。例如：
HeisfiveyearsolderthanI.
Igotupanhourearlierthantheothers.
⑵最高级的用法
①三者或三者以上相比，表示最高程度时，用“the+最高级”的结构表示。这种句式一般常有表示比较范围的介词短语。例如：
ZhangHuaisthetallestofthethree.
Heworks(the)hardestinhisclass.
TheThreeGorgesareaisoneofthemostbeautifulareasofChina.
②最高级可被序数词以及byfar,bynomeans,much,nearly,almost,notquite,nothinglike等词语修饰。例如：
TheYangtzeRiveristheworld’sthirdlongestriver.
Howmuchdidthesecondmostexpensivehatcost?
Thishatisbyfar/bynomeans/much/nearly/notnearly/almost/notquite/nothinglikethebiggest.
[注意]：
a)作状语的副词最高级前可以不加定冠词。例如：
Hecame(the)earliestofalltheboys.
b)excellent(优秀的、极好的)，extreme（极端的），favourate(最喜爱的)，perfect（完美的）等词本身含有最高级的含义，所以它们没有比较级和最高级。
c)形容词最高级修饰作表语或介词宾语的名词、代词时，被修饰的词往往省略。
Heisthetallest(boy)inhisclass.
⒊使用形容词、副词的比较等级时要注意的几个问题
⑴在as-----as之间只能使用原级形容词（副词）。例如：
误：Ihaveaslessmoneyasyoudo.
正：Ihaveaslittlemoneyasyoudo.
⑵切忌采用双重比较
比较级前可以用表示程度的修饰语来表示强调或程度，但不可用more加比较级形式。例如：
误：Hishealthismoreworsethanbefore.
正：Hishealthisworsethanbefore.
⑶应避免自我比较
使用比较级时，进行比较的双方必须是互相分离、互不包含的独立概念或事物，否则比较就不合逻辑。例如：
误：Bambooprobablyhasmoreusesthananyplantintheworld.
正：Bambooprobablyhasmoreusesthananyotherplantintheworld.
[附]比较的另一方如果是不定代词anyone,anything,前面不能加other,而要在其后加else.例如：
Shestudiesharderthananyoneelseinherclass.
但是，若比较的双方不属于同一范围，句中则不加other。例如：
Sherunsfasterthananyboyinherclass.
⑷表示“两者中较-------”时，比较级前要加the。例如：
Theolderofthetwonoblementookalightandledmeintoabackroom.
⑸被比较的双方必须具有可比性。例如：
误：Therearemorestudentsinthisschoolthanthatschool.
正：Therearemorestudentsinthisschoolthaninthatschool.
⑹连词than后使用代词主格和宾格有时意义不同。例如：
①Iknowyoubetterthanhe.我比他更了解你
②Iknowyoubetterthanhim.我对你的了解比对他的了解更透彻些（或：“我比他更了解你”，此时与①同义）。
⑺使用最高级时，主语不可被排除在最高级所指的范围之外。例如：
误：Heisthetallestofallhisbrothers.
正：Heisthetallestofallthebrothers.
⑻most前面加不定冠词a/an，或者不加冠词修饰形容词时，它的意思等于very。此时，most已失去最高级的意义。试比较：
amostinterestingfilm(一部很有趣的电影)/themostinterestingfilm(最有趣的电影)

附》关于本单元模块整体备课的特别说明：
本人在本单元模块的整体备课上主要遵循了“创造性、灵活性、有效性”的三大原则，为此，特意对原有教材的编排体系进行了重新整合，同时对原有教学素材进行了灵活取舍。但是，这种整合与取舍不是随意的，主要考虑到以下三个方面因素的制约：第一，为完成应有的教学任务，实际分配到每个单元模块的教学课时一般只有5~6课时；第二，每一课时的信息容量应合乎情理；第三，组合的话题之间有时是出于外在形式的需要，但更多是出于其内在的必然联系（如listening和everydayEnglish之间的组合）。此外，为提高教案的情景化和可操作程度，我适当在教案中加入了一些图片。
需要补充说明一下的是，本教案的阅读课时安排的是两课时，但本教案只体现出了一课时左右的内容，原因在于另一课时主要集中处理阅读课文中的语言知识点，大家都轻车熟路了，没有再累述出来的必要；另外，在处理grammar部分时，我的安排是开始让学生主动体验(experience)和发现(discover)要讲解的grammar,然后老师集中讲解，在讲解时考虑到平时语法课的实际效果，所以我在这一步骤的教案上主要使用的是汉语。

话题导入
人类从日常生活到宇宙探索都离不开科学技术。如果没有科学的发展,我们将仍然处于愚昧无知的原始状态,科学技术是第一生产力,它推动了社会经济、文明的发展,使我们人类成为了宇宙的主人。作为中学生,我们应该以“八荣八耻”中的“以崇尚科学为荣、以愚昧无知为耻”为行为准则,把智慧和热情投入到科学研究和探索中。

背景资料
什么是铁？?
铁位于周期表第四周期第Ⅷ族。元素符号为Fe,原子序数为26,是一种重要的过渡元素。光亮的银白色金属,密度7.86g／cm3,熔点1535℃,沸点2750℃。纯铁的抗蚀力相当强,但通常的铁都含有碳和其他元素,因而使它的熔点降低,抗蚀力也减弱。铁有延展性和导热性，也能导电。但导电性比铜、铝都差。铁能被磁体吸引,在磁场作用下,铁自身也能产生磁性。?
铁为什么会生锈？?
铁放的时间长了就会生锈。铁容易生锈,除了由于它的化学性质活泼以外,同时与外界条件也有很大关系。水分是使铁容易生锈的物质之一。然而,光有水也不会使铁生锈,只有当空气中的氧气溶解在水里时,氧在有水的环境中与铁反应,才会生成一种叫氧化铁的东西,这就是铁锈。铁锈是一种棕红色的物质,它不像铁那么坚硬,很容易脱落,一块铁完全生锈后,体积可胀大8倍。如果不除去铁锈,这海绵状的铁锈特别容易吸收水分,铁也就烂得更快了。??
