教材分析和教材重組
教材分析
本單元的主要內(nèi)容是邊緣科學(xué)、地球生命的起源，萬有引力、黑洞和太空旅行等天文學(xué)知識。通過本單元的學(xué)習(xí)，培養(yǎng)學(xué)生對科學(xué)的興趣，激發(fā)學(xué)生探究科學(xué)的熱情。
1.WarmingUp部分共有三組問題，第一組問題引導(dǎo)學(xué)生討論邊緣科學(xué)(FrontierScience)，即以兩種或多種學(xué)科為基礎(chǔ)而發(fā)展起來的科學(xué)。例如，生物化學(xué)是以生物學(xué)和化學(xué)為基礎(chǔ)的邊緣科學(xué)。第二組問題探討科學(xué)研究的方法。第三組問題讓學(xué)生思考要成為真正的科學(xué)家所必須掌握的技能。
2.Pre-reading部分主要讓學(xué)生弄清楚什么是科學(xué)思想，什么是宗教信仰或文化傳統(tǒng)。學(xué)生總喜歡聽故事或講故事，在探討生命的起源的科學(xué)道理之前，讓學(xué)生交流一下有關(guān)宇宙的起源的種種傳說，既有趣味性，又能調(diào)動學(xué)生的相關(guān)知識，激活學(xué)生的思維。
3.Reading部分講述了地球上生命的起源。水的形成使得地球有別與其他星球，它使得地球上生命的誕生成為可能。科學(xué)家認(rèn)為，地球上的生命首先誕生于水中，上百萬年后，陸地上才長出綠色植物，隨后出現(xiàn)了陸棲動物和水陸兩棲動物。最初的動物靠孵化繁衍后代，后來出現(xiàn)了哺乳動物，人類也隨之誕生了。文章最后講述的現(xiàn)象發(fā)人深省：Theearthmaybecometoohotforthelivesonit.它關(guān)系到地球上生命的未來。
4.Comprehending部分通過四個選擇填空題檢測學(xué)生對本文核心問題的理解：地球上生命的起源和延續(xù)需要哪些條件?隨后通過排序的方式幫助學(xué)生弄清本文的行文線索，也就是地球上生命的起源和發(fā)展歷程。最后提出兩個問題，考查學(xué)生的深層理解和推斷能力。
5.LearningaboutLanguage部分首先通過英文解釋幫助理解課文中的生詞，然后，通過短文填空、詞語分類等形式將這些詞語用于一個相關(guān)的情境中。語法部分也是采用先發(fā)現(xiàn)后應(yīng)用的學(xué)習(xí)方法。先通過到課文中找句子，讓學(xué)生認(rèn)識主語從句，然后，設(shè)置一個用手機發(fā)短信息的情境，讓學(xué)生進行簡單句與主語從句之間的轉(zhuǎn)換練習(xí)。最后設(shè)置情境來復(fù)習(xí)第三單元出現(xiàn)的表語從句。
6.UsingLanguage部分綜合訓(xùn)練聽說讀寫的能力。聽力部分的內(nèi)容介紹三位科學(xué)巨匠，不僅通過聽力填表的形式訓(xùn)練學(xué)生捕捉細(xì)節(jié)的能力，還通過四選一的形式幫助學(xué)生找主題思想。在解釋對與錯的過程中，教師可以適當(dāng)?shù)亟榻B一下概括主題的方法。閱讀部分是一個科幻小故事，通過“我”和“我的朋友”乘宇宙飛船登月球的經(jīng)歷，介紹了重量、失重和地球引力等科學(xué)道理。說和寫部分以Visitingthemoon為話題，要求學(xué)生討論登月球需要攜帶的物品和在月球上可能遇到的困難，并要求學(xué)生找出克服這些困難的方法。教師可以根據(jù)課本上的提示，向?qū)W生介紹“先分述后總結(jié)”的寫作方法。提出問題的解決方案時，要求學(xué)生選用適當(dāng)?shù)摹爸甘尽庇谜Z。
教材重組
1.將WarmingUp，Pre-reading，Reading與Comprehending整合在一起上一節(jié)“閱讀課”。
2.將LearningaboutLanguage和Workbook的usingwordsandexpressions及usingstructures整合在一起上一節(jié)“語言學(xué)習(xí)課”。
3.將UsingLanguage設(shè)計為一節(jié)包括聽說讀寫在內(nèi)的“綜合技能課（一）”。
4.將Workbook的READINGANDLISTENING和TALKING結(jié)合在一起上一節(jié)“聽說課”。

“Willyougofishingthisafternoon?”“Well,italldependsontheweather.”“你今天下午去釣魚嗎？”“得看天氣?！?br> formillionsofyearstocome中不定式tocome作定語，與前面的名詞之間有邏輯上的主謂關(guān)系，例如：
Sheisthelastpersontodosuchathing.她是最不像做這種事的人。

主語從句
一、由what（whatever，whoever）等代詞引導(dǎo)的主語從句。
Whattheyareafterismoney.他們追求的是金錢。
Whateverwassaidheremustbekeptsecret.這里說的話都應(yīng)當(dāng)保密。
二、由連詞that引導(dǎo)的主語從句。其中that一般不可省略，但若用it作形式主語，that從句后置時，則可省略。為避免頭重腳輕，我們傾向用it開頭，后接be，seem等。如果句子是疑問形式，就只能用帶it的結(jié)構(gòu)。
Thatmoneydoesntgrowontreesshouldbeobvious.
金錢不能從樹上長出來是顯而易見的。
Itisobvious（that）moneydoesntgrowontrees.顯而易見，金錢是不能從樹上長出來的。
Hasitbeenannouncedwhentheplanesaretotakeoff？飛機什么時候起飛宣布了沒有？
注意：
1）選用what還是用that引導(dǎo)主語從句要根據(jù)關(guān)聯(lián)詞在從句中是否擔(dān)任成分而定。且what（以及whatever，whoever等）引導(dǎo)的主語從句一般不用it作形式主語。
Whathesaidistrue.他說的是真的。（what在其引導(dǎo)的主語從句中作賓語。）
ThatChinaisagreatsocialistcountryiswellknown.（=It’swellknownthat…）眾所周知，中國是一個偉大的社會主義國家。（that在其引導(dǎo)的主語從句中不作任何成分，也無詞義，只起連接作用。）
2）it引導(dǎo)的強調(diào)句與it作形式主語的復(fù)合句不可混淆。it引導(dǎo)的強調(diào)句是用來對句中某一成分加以強調(diào)，其結(jié)構(gòu)為：“Itis（或was）+強調(diào)部分+that（或who）…”強調(diào)句去掉Itis（或was）…that（或who）…框架后，剩余部分為一個完整的句子。
ItwasIthat(who)metMaryinthestreetyesterday.是我昨天在街上遇見了瑪麗。(強調(diào)主語)
3）常見的用it作形式主語的復(fù)合句結(jié)構(gòu)：
*Itis+形容詞（necessary，strange，important，wonderful，possible，likely，等）+that從句，從句中常用虛擬語氣。
It’snecessarythathewritesomethinginEnglish.他用英語寫點東西是必要的。
It’sstrangethatshedidnotgotoschoolyesterday.奇怪的是她昨天沒去上學(xué)。
*Itis+名詞（afact，apity，nowonder，goodnews，等）+that從句
Itsapitythatsheshouldhavesaidso.真遺憾她竟然會這么說。
*Itis+過去分詞（said，reported，decided，unknown等）+that從句
ItssaidthatourEnglishteacherwillgoabroadnextweek.據(jù)說我們英語老師下周要去出國。
*It+不及物動詞（seems，appears，happens，matters等）+that從句
Itseemsthatsheisingreatneedofhelp.看來她急幫忙。
4）主語為從句時，一般要用單數(shù)謂語動詞形式；但如果引導(dǎo)的從句作主語、代表復(fù)數(shù)概念（?？蓮谋碚Z上看出）時，謂語動詞則常用復(fù)數(shù)形式：
Whatweneediswater.我們需要的是水。
Whatweneedareusefulbooks.我們需要的是有用的書。
三、由連接代詞或連接副詞（或if,whether）引導(dǎo)的主語從句。
Whentheywillcomehasntbeenmadepublic.他們什么時候回來還沒有宣布。
WhetherI’llattendthemeetinghasn’tbeendecided.=Ithasn’tbeendecidedwhether(if)I’llattendthemeeting.我是否參加會議還未決定。

1.澳大利亞出產(chǎn)羊毛。
2.父親把零錢放進錢包。
3.他們敏捷的行動阻止了火勢蔓延。
4.你不能永遠(yuǎn)依賴你的雙親。
5.我們初次見面到如今已有好多年了。


1.B因謂語動詞dependson，說明gocamping這件事尚未確定。主語從句在句首時，不用if，故用whether。
2.A本句兼考查主語從句與表語從句。
3.C此題中有兩個不是并列的動詞謂語，而Anyone和Theperson不是連接代詞，也不是關(guān)系代詞，所以先排除A和B；又whoever=thepersonwho,故選C.
4.A本句考查“dowhatonecan（do）”這一句型。用whatever代what語氣更強。
5.Cwhat引導(dǎo)主語從句，在從句中做主語，it是形式主語；that引導(dǎo)主語從句時，只起引導(dǎo)作用，不作任何成分。
6.A主語從句wecan’tget后缺賓語，故需用what；而than后分句也缺賓語，仍需用what。
7.D根據(jù)句子結(jié)構(gòu)可知本題考查名詞性從句用法，故A、B項排除；whatever與whichever的不同之處在于前者沒有范圍而后者有范圍，而本句中所表達(dá)的是在本周六參加比賽的獲勝隊，是有范圍的，故D項正確。
8Awhat引導(dǎo)主語從句，在主語從句中作主語。表語從句部分是說明該商店與眾不同的具體內(nèi)容，并未指人，因此排除B、D兩項；whatever：anythingthat…意為“……的任何事物”，不合句意，故排除。
9.B根據(jù)題干中的…todois…可知主語從句中缺少主語，而選項中能作主語從句主語的只有what。
10.C此句中it作形式主語，代替后面的that從句，而且that從句內(nèi)容與require構(gòu)成被動關(guān)系，故C項正確。

高二英語Scienceversusnature教案

高二英語Scienceversusnature教案
Verb-edform
一、V-ed分詞具有形容詞和副詞性質(zhì)，在句中可充當(dāng)定語、表語、賓語補語、狀語。
1．作定語
過去分詞作定語，表示已經(jīng)完成的被動的動作或狀態(tài),但不及物動詞構(gòu)成的過去分詞只表示完成，而不表示被動意義。
例如：完成+被動：apollutedriveralockedroomawell-educatedman
只有完成：aretiredworkerafallenleafboiledwater
作定語的V-ed分詞也有前置和后置兩種情況。單個過去分詞作定語，常常位于被修飾的名詞前；而過去分詞短語作定語時，常常位于被修飾的名詞后面，相當(dāng)于一個定語從句。
Eg.1).Youshouldimproveyourspoken(speak)English.
2).What’sthelanguagespoken(speak)inthatarea?
=.What’sthelanguagewhich/thatisspoken(speak)inthatarea?
3).Thefiremenweretryingtorescuethepeopletrappedinthefire.
=Thefiremenweretryingtorescuethepeoplewhowastrappedinthefire.
4).Themeeting,attendedbyonethousandstudents,wasasuccess.
=Themeeting,whichwasattendedbyonethousandstudents,wasasuccess.
2．作表語
作表語的V-ed分詞大多轉(zhuǎn)化成為形容詞，通常用于聯(lián)系動詞之后（例如be,seem,appear,look,sound,feel,remain,stay,become,get等），表示主語所處的狀態(tài)
1).Edisonbecameinterested(interest)insciencewhenhewasveryyoung.
2).Shelooksveryexcited(excite)atthenews.
3).WhenIwascleaningthewindow,myfingergotcut(cut)unexpectedly.
3．作賓語補足語
如果賓語與后面作賓補的動詞構(gòu)成被動關(guān)系，則使用V-ed分詞作賓補。可以帶V-ed分詞作賓補的詞有：with,see,watch,observe,notice,lookat,hear,listento,feel,sense,find,leave,keep,get,have,make.
1).Ihadmymoneystolen(steal)onthebus.
2).AsheknowslittleEnglish,hefindsitdifficulttomakehimselfunderstood(understand).
3).Inthemorning,peoplewokeupandfoundtheworldoutsidetheirhousescompletelychanged(change).
4．作狀語
作狀語的V-ed分詞與主句之間常有逗號隔開,在句中可表示時間,原因,條件,讓步,伴隨等情況,并可轉(zhuǎn)化為相應(yīng)的狀語從句。作狀語的V-ed和主句的主語常有被動關(guān)系。
1)時間狀語
Seenfromspace,theearthlooksblue.
=Whentheearthisseenfromspace,itlooksblue.

Askedwhathadhappened,heloweredhishead.
=Whenhewasaskedwhathadhappened,heloweredhishead.
2)原因狀語
Bornintoapoorfamily,hehadonlytwoyearsofschooling.
=Ashewasbornintoapoorfamily,hehadonlytwoyearsofschooling.
Becausetheyweremovedbythestory,theydecidedtohelpher.
=Movedbythestory,theydecidedtohelpher.
3)條件狀語
Givenmoretime,wearesuretofinishit.
=Ifwearegivenmoretime,wearesuretofinishit.
Comparedwithotherprofessors,sheisanexcellentspeaker.
=.
4)讓步狀語
Laughedatbyeverybody,hehadmysympathy.
=Thoughhewaslaughedatbyeverybody,hehadmysympathy.
Eventhoughhewasdefeatedbyhisopponent,hestillisaheroinmyheart.
=Defeatedbyhisopponent,hestillisaheroinmyheart.
5)伴隨狀語
Theboysatatthetableburiedinhishomework.
=Theboysatatthetableandhewasburiedinhishomework.
Thegirllayinbedlostinthought.
=Thegirllayinbedandshewaslostinthought.
Iwillspendthenightlocked(lock)inyourroom.
Shelefttherestaurant,disappointed(disappoint)withthebadservice.
二、轉(zhuǎn)化為形容詞的V-ed
有一些過去分詞已轉(zhuǎn)化為形容詞,失去被動意義,僅表狀態(tài)。如:hidden,dressed,lost,seated,determined,absorbed,injured,based,surprised,satisfied,bored,tired…
e.gWhatmadeyousofrightened?
Thedog,boredwiththegame,willnotplayanymore.
=Thedog,whichisboredwiththegame,willnotplayanymore.
Muchinterested,heagreedtogiveitatry.
=Ashewasmuchinterested,heagreedtogiveitatry.
Seatedinthecar,thePresidentwavedtothecrowd.
=Whilehewasseatedinthecar,thePresidentwavedtothecrowd.
三、連詞+V-ed
過去分詞有時和連詞(when,while,whenever,until,if,unless,once,though,
although，eventhough/if)一起用，相當(dāng)于狀語從句的緊縮式。
（注意：before/after后不直接跟V-ed分詞，而用before/after＋beingdone,因為此時分詞前的before/after是介詞。）
Ifaccepted(accept)forthispost,youwillbeinformedbyMay1st.
Unlesschanged(change),thislawwillmakelifedifficultforfarmers.
Iwillnotgiveupmyplaneveniftold(tell)to.
Thesemachinesmustbecheckedbeforebeingused(use).

四、tobedone,beingdone,done,havingbeendone作定語的區(qū)別：
以上四種形式都表示被動，都可作定語。tobedone表示即將被…;beingdone表示正在被…;done表示被做過了…;havingbeendone作非限制性定語，和被修飾詞用逗號隔開,強調(diào)在謂語動詞的動作之前完成。
Thequestiontobediscussed(discuss)tomorrowinvolvespollution.
Thequestiondiscussed(discuss)yesterdayinvolvespollution.
Thequestionbeingdiscussed(discuss)nowinvolvespollution.
Thequestion,havingbeendiscussed(discuss)foryears,involvespollution.
五、done,havingbeendone作狀語的區(qū)別：
beingdone一般在句中不作狀語,而用done代替之。havingbeendone強調(diào)動作在謂語動作之前完成,或已經(jīng)持續(xù)一段時間的動作,常用作時間和原因狀語,done則不強調(diào)時間先后和持續(xù)一段時間。
Led(lead)bythelocalguide,wewentfurtherintotheforest.
Havingbeentaken(take)goodcareofforhalfayear,thepatientbecamefarbetter.
Havingbeentranslated(translate)intomanylanguages,thenoveliswell-knownthroughouttheworld.

高二英語Understandingeachother教案

虛擬語氣（TheSubjunctiveMood）

虛擬語氣用于表示主觀愿望和假設(shè)的虛擬情況。所講的內(nèi)容往往是與事實相反的；或是其實現(xiàn)的可能性微乎其微，甚至于沒有實現(xiàn)的可能性。當(dāng)然，有時為了使說話的語氣客氣、緩和、委婉，也使用虛擬語氣.

虛擬語氣是英語語法中的難點?？忌鷳?yīng)主要掌握虛擬語氣在下列情況下的用法：

①虛擬語氣在非真實條件句中的用法；

②在賓語從句中的用法；

②在狀語從句中的用法；

④及主語從句、同位語從句、表語從句中的用法；

⑤在一些特殊句型中的用法等。

一、用于非真實條件句中的虛擬語氣

。

If從句的謂語形式

主句的謂語形式

與過去事實相反

haddone

wouldhavedone

與現(xiàn)在事實相反

did/were

woulddo

與將來事實相反

did/were

shoulddo

weretodo

woulddo

注意點：

1.省略If當(dāng)條件狀語從句的謂語含有were,had,should時，可以將它們放在句首，省略if。

1.Ifheshouldactlikethatagain,hewouldbefiredimmediately.

=Shouldheactlikethatagain,hewouldbefiredimmediately.

2.Ifyouwerethemanagerhere,whatwouldyoudo?

=___Wereyouthemangerhere_______________,whatwouldyoudo?

______Ifitshouldrain____/_________Shoulditrain____tomorrow(如果明天下雪),wewouldputoffourcelebration.

__Ifyouhadattended______/___Hadyouattended______________thelecture(如果你聽了講座),youcouldhaveknownthespecialcustoms.

2.錯綜時間條件句

當(dāng)條件狀語從句表示的行為和主句表示的行為所發(fā)生的時間不一致時，被稱為"錯綜時間條件句",動詞的形式要分別根據(jù)它所表示的不同時間作相應(yīng)的調(diào)整

1）Ifhehadfollowedthedoctorsadvice，hewouldrecoveralready．如果他遵照醫(yī)生的勸告，現(xiàn)在病就好了。（從句與過去事實相反，主句與現(xiàn)在事實相反。）

2）IfI___were______(be)you，I__wouldn’thavemissed___(notmiss)thefilmlastnight．

3)Iftheboy__________hadn’tsaved_(notsave)thisafternoon,hisfamily_wouldn’tbe_(notbe)inpeacenow.

4)Ifyouworked(work)hardnow,you_wouldget___(get)agoodjobinthefuture.

5)Ifhehadn’tbeencaught(notcatch)intherainyesterday,he______wouldn’tbe__(notbe)illnow.

二．虛擬語氣用于某些從句中的情況：
1）在主語從句中
在It+be+形容詞/名詞+that從句的結(jié)構(gòu)中，由于某些形容詞/名詞的原因，that從句中的謂語動詞要用虛擬式"should+動詞原形"或是"動詞原形"。

這類形容詞/名詞常見的有：important（重要的）,necessary(必要的）,strange（奇怪的）,natural（自然的）,essential（絕對必要的）,urgent（緊急的）,advisable(明智的),regretful（遺憾的）,duty（義務(wù)、責(zé)任）,apity（遺憾）,nowonder（難怪）,aregret（遺憾）：
Itisstrangethathe___say______________(say)so.

Itisagreatpitythatyou____think_____________(think)so.
Itisnaturalthatabird___rest_________(rest)intrees.
Itisnecessarythathe___besent___________(send)toBeijingrightaway.

另外，下列結(jié)構(gòu)中主語從句的謂語動詞也要求用虛擬語氣：
Itisorderedthat…(根據(jù)命令、要求……),Itisproposedthat…(人們建議……)
Itisdesiredthat…(最好、需要……),Itisrequestedthat…(人們要求……)
Itissuggestedthat…(有人建議……),Itisrecommendedthat…(有人推薦……)
Itisdemandedthat…(根據(jù)要求……),等。例如：
ItissuggestedthattheEnglishevening_beheld________(hold)onSaturday.

2)在賓語從句中
一個堅持，兩個命令，三個建議，四個要求。即1.insist2.order,command3.advise,suggest,propose4.demand,require,request,desire這些動詞后面的賓語從句要使用虛擬語氣用法。即從句中的動詞使用should+v，或者將should省略。以上動詞相應(yīng)的名詞構(gòu)成的名詞性從句包括主語從句，表語從句和同位語也要使用虛擬語氣。(order,advice,suggestion,proposal,demand,request,desire)

Heproposedthatwe_set________(set)adeadlineforthecomplementoftheplan.
Theyrequestedthatwe__send___________(send)adelegationtotheircountry.
Isuggestedthathe___set_______(set)offforourheadquartersstraightaway.
注意：當(dāng)insist表示“堅持說”、suggest表示“表明，顯示”時，不用虛擬語氣。

Thelookonhisfacesuggestedthathe__was________(be)quitesatisfiedwithwhatIhaddoneforhim.

Heinsistedthathe_was__________(be)honest.

3)在表語從句和同位語從句中
名詞suggestion（建議）,proposal（提議）,order（命令）,recommendation（推薦），advice(建議)等后面所接的表語從句和同位語從句中，謂語動詞要用"(should)+動詞原形"：
Mysuggestionisthathe__leave_______(leave)forLondonatonce.

Whatdoyouthinkofhisproposalthatwe__put_________(put)onaplayattheEnglishevening?

4)在狀語從句中
asif、asthough（似乎，仿佛）引出的方式狀語從句，如果表示真實情況應(yīng)該用陳述語氣；如果表示非真實情況則應(yīng)該用虛擬語氣,過去用haddone,現(xiàn)在用did/were,將來用woulddo

Theyaretalkingasifthey__hadbeen_________(be)friendsforyears.

Theteachertreatsthestudentsasifthey_were_________(be)hisownchildren.

Theyaretalkingandtalkingasifthey____wouldn’tmeet_____(notmeet)again

5)在Itis(high)timethatsbdid/weresth從句中"該是……的時候了",

Itistimethatwe__got______(get)readyforthefinalexamination.

Itishightimethatwe__had_______(have)ourlunch.

6)在Ifonly/wish…從句中"要是……就好了"、"但愿……"

過去：haddone現(xiàn)在：did/were將來：woulddo
Ifonlyhe____wouldfind_______(find)asatisfactoryjobafterhisgraduation.
