m.教材分析與教材重組

i.教材分析

本單元以“Lifeinthefuture"為中心話題，旨在通過本單元的學(xué)習(xí)，讓學(xué)生大膽發(fā)

揮想象，對人類今后的生活環(huán)境，生活方式進(jìn)行猜測，并在此基礎(chǔ)上，對人類的種種活動進(jìn)

行反思，提倡環(huán)保生活意識。同時讓學(xué)生學(xué)會過去分詞作定語和作狀語的不同用法。最后讓

學(xué)生將本單元所討論的話題和推測手法相結(jié)合，學(xué)習(xí)怎樣寫reports

1.1WarmingUp部分利用一個關(guān)于“住”和“行”的對比研究表格引導(dǎo)學(xué)生回顧過去，

認(rèn)識現(xiàn)在和展望未來。通過這一活動，引發(fā)學(xué)生對過去，現(xiàn)在和未來的思考，使學(xué)生對將要

閱讀的文章有個知識準(zhǔn)備。

1.2Pre-reading部分讓學(xué)生充分運(yùn)用發(fā)散思維，先列舉當(dāng)今世界人類面臨的一些突出

問題,然后要求學(xué)生思考為什么會產(chǎn)生這些問題，這些問題中哪些在未來社會仍然可能存在,

哪些將會被克服，哪些將會惡化。為下面的閱讀做了鋪墊。

1.3Reading部分通過一封發(fā)自未來的電子郵件，講述了作者LiQiang怎樣安全到達(dá)

“未來世界”，他對“未來世界”的印象，以及“未來世界”的日常生活方式和交通工具情

況。閱讀時要把重點放在“未來世界”生活與當(dāng)今生活的不同點上。

1.4Comprehending部分設(shè)計了三個教學(xué)活動來加深學(xué)生對Reading部分的理解。第一

個活動要求學(xué)生通過閱讀找出“未來世界”在以下幾個方面的變化：跨時空旅行，交通，住

房，城鎮(zhèn)環(huán)境和空氣質(zhì)量。接著讓學(xué)生在此基礎(chǔ)上得出自己的結(jié)論，哪些變化好，哪些變化

不好，并說明理由。第二個活動要求學(xué)生通過閱讀來判斷LiQiang對“未來世界”的態(tài)度

是樂觀的還是悲觀的。學(xué)生要在文中找出支持自己觀點的論據(jù)，盡可能說服別人。第三個活

動讓學(xué)生想象一下LiQiang將會去參加哪些活動。這樣既鼓勵學(xué)生展開豐富的想象，又為

UsingLanguage部分的語篇學(xué)習(xí)做了鋪墊。

1.5LearningaboutLanguage部分突出了本單元的一些重點詞匯及語法。首先通過完

成語篇來考查學(xué)生運(yùn)用本單元詞匯的能力，并且通過練習(xí)，讓學(xué)生區(qū)分兩種動詞短語，一種

是以動詞為中心的詞組，另一種是以介詞為中心的詞組。語法部分要求學(xué)生主動找出閱讀語

篇中的重點結(jié)構(gòu)一一過去分詞作定語和狀語，然后加以應(yīng)用。

1.6UsingLanguage部分涵蓋了聽，說，讀，寫四項語言基本技能。要求學(xué)生通過閱

讀IHAVESEENAMAZINGTHINGS一文，對LiQiang旅行的第三站有個總體的印象，并能

找出部分細(xì)節(jié)知識。

1.7SUMMINGUP部分歸納了本單元的主要學(xué)習(xí)內(nèi)容并讓學(xué)生自我檢測一下學(xué)習(xí)效果。

1.8LEARNINGTIP部分告訴學(xué)生在討論時記筆記的好處和方法。

2.教材重組

2.1可將WarmingUp,Pre-reading,Reading和Comprehending整合在一起上一節(jié)

精讀課。

2.2UsingLanguage中的reading和listening是LiQiang'straveltothe

future的延續(xù)，可將這兩部分及Workbook中的LISTENING整合起來上一節(jié)聽力課。

2.3可將LearningaboutLanguage和Workbook中的USINGWORDSANDEXPRESSIONS

及USINGSTRUCTURES整合起來上一節(jié)語法課。

2.4將Workbook中的READINGTASK和LISTENINGTASK結(jié)合起來上一節(jié)泛讀課，

進(jìn)一步拓展學(xué)生的思維和想象力。

2.5將UsingLanguage中的speaking和Workbook中的TALKING整合在一起上一節(jié)

口語課，鼓勵學(xué)生對現(xiàn)在進(jìn)行反思，對未來進(jìn)行大膽猜測(makepredictions)。

2.6將Workbook中的SPEAKINGTASK和WRITINGTASK整合起來上一節(jié)寫作課，同

時對整個單元進(jìn)行一個小結(jié)。

過去分詞作狀語：

用作狀語的過去分詞通常來自及物動詞。過去分詞用作狀語時，修飾主句的謂語動詞，意義

上相當(dāng)于狀語從句，表示時間、條件、原因、伴隨狀況等。過去分詞作狀語，前邊往往可以

加when,while,asif,asthougho一般說來，這種結(jié)構(gòu)的邏輯主語必須與主句的主語一

致。例如：

Wheneverpraised,sheblushes.（作時間狀語）

二Wheneversheispraised,sheblushes.

United,westand;divided,wefall.（作條件狀語）

二Ifweareunited,westand;ifwearedivided,wefall.

Writteningreathaste,thisbookisfulloferrors.（作原因狀語）

2.Tomorrowyouwillbereadyforsomevisitsorganizedbythecompany.

=Tomorrowyouwillbereadyforsomevisitsthat/whichwasorganizedbythecompany.

過去分詞作定語：

a.用作前置定語的過去分詞通常來自及物動詞，帶有被動意義和完成意義。例如：

Welikeskatinginthefrozenlakeinthewinter.

=Welikeskatinginthelakewhichhasbeenfrozeninthewinter.

Howmanyfinishedproductshaveyougotuptonow?

=Howmanyproductsthathavebeenfinishedhaveyougotuptonow?

來自不及物動詞的過去分詞很少能單獨用作前置定語，能作這樣用的僅限以下幾個詞，這時

僅表示完成意義，不表示被動意義：

aretiredworker=aworkerwhohasretired

anescapedprisoner=aprisonerwhohasescaped

afaded/witheredflower=aflowerthathasfaded/withered

fallenleaves=leavesthathavefallen

therisensun二thesunthathasjustrisen

areturnedstudent=astudentwhohasreturned

vanishedtreasure=treasurethathasvanished

b.用作后置定語的過去分詞通常也來自及物動詞，表示被動意義和完成意義。這明相當(dāng)于

一個定語從句。例如：

Thingsseenarebetterthanthingsheard.

=Thingsthat/whichareseenarebetterthanthingsthat/whichareheard.

過去分詞作表語：

過去分詞作表語表示主語所處的狀態(tài)。用作表語的過去分詞大多來自及物動詞；不及物動詞

的過去分詞能作表語的只限于少數(shù)表示位置轉(zhuǎn)移的動詞，如g。，come,assemble等，它們

用在聯(lián)系動詞之后，表示完成意義，無被動意義。例如：

Themanlookedquitedisappointed.

Heisgreatlydiscouragedbyherrefusal.

Hishairisnearlyallgone.

已經(jīng)形容化了的過去分詞大多可作表語，常見的有：

accomplished,amazed,amused,astonished,broken,closed,completed,complicated,

confused,crowded,devoted,disappointed,discouraged,drunk,excited,frightened,

hurt,interested,lost,satisfied,surprised,worried等。

過去分詞作賓語補(bǔ)足語：

a.see,hear,feel,find,think等表示感覺和心理狀態(tài)的動詞可以帶過去分詞作賓語補(bǔ)

足語。例如：

Tomfoundhimselfinvolvedinanawkwardsituation.

IsawTomdressedlikeabeggarinthestreet.

Everybodythoughtthematchlostuntilthelastminute.

b.make,get,have,keep等表示“致使”意義的動詞可以帶過去分詞作賓語補(bǔ)足語。例

如：
