huì)和文化形態(tài)發(fā)生了重大變化。地球村是互聯(lián)網(wǎng)的發(fā)展；是信息網(wǎng)絡(luò)時(shí)代的集中體現(xiàn)；是知識(shí)經(jīng)濟(jì)時(shí)代的一種形式；而現(xiàn)代交通工具的飛速發(fā)展，通信技術(shù)的更新?lián)Q代，網(wǎng)絡(luò)技術(shù)的全面運(yùn)用使地球村得以形成。Ⅲ.學(xué)習(xí)策略形成如何有效地進(jìn)行聽說訓(xùn)練1．聽懂文章大意在聽力過程中，不能只在意單詞，要在意句子本身的意思，有些地方聽不懂沒關(guān)系，要了解整篇文章在說什么。2．積累語言知識(shí)整理每次聽力材料中的新知識(shí)點(diǎn)、新單詞，通過語境去記憶。3．訓(xùn)練聽說能力聽說能力可以從聽寫、精聽、跟讀和復(fù)述四個(gè)方面來訓(xùn)練。(1)聽寫：先總體聽一遍材料，了解大意；然后聽文章句子，寫下來，倒回去再聽；直到把它完全寫出來。(2)精聽：將聽力材料一字一句地寫下來，精確到標(biāo)點(diǎn)符號(hào)。(3)跟讀：先對(duì)照著文本，精聽至少三遍；然后嘗試以相同的節(jié)奏跟讀聽力材料，不斷地跟讀，理想情況下平均8遍之后可以跟上材料的語速。(4)復(fù)述：整段復(fù)述(保證段落長(zhǎng)度的復(fù)述時(shí)間不超過1分鐘)。4．不要害怕犯錯(cuò)誤學(xué)習(xí)英語口語是在不斷犯錯(cuò)誤的過程中練習(xí)、進(jìn)步的。因此練口語應(yīng)該積極主動(dòng)，克服害羞心理，利用一切機(jī)會(huì)講英語。1．conveniencen．方便，便利；便利的事物convenientadj.方便的；便利的inconveniencen.不方便；不便inconvenientadj.不方便的provideconvenience(教材P6)提供便利[合作探究]體會(huì)convenience及其派生詞的用法和意義Wehopetodiscussbusinesswithyouatyourearliestconvenience.我們希望盡早與你方洽談業(yè)務(wù)。Wehaveprovidedseatsfortheconvenienceofourcustomers.為方便顧客，我們備有座位。WillitbeconvenientforyoutochatwithmeontheInternettonight?你今晚和我網(wǎng)上聊天方便嗎？[自主發(fā)現(xiàn)]①atone’sconvenience在某人方便的時(shí)候②forone’sconvenience(of)＝fortheconvenienceofsb為了某人的方便③Itisconvenientforsbtodosth某人方便做某事[名師提醒]convenient作表語時(shí)，不可用人作主語，要用物作主語或用it充當(dāng)形式主語。表達(dá)“如果你方便的話”和“在你方便的時(shí)候”時(shí)，要分別用ifitisconvenientforyou和whenitisconvenientforyou。[詞塊積累]forconvenience為了方便起見conveniencefood/store方便食品/便利店[鞏固內(nèi)化](1)單句語法填空①Thesegatesarealwaysopenfortheconvenienceofvisitors.②Anyhelpfromyouwillbegreatlyappreciated.Pleasegivemeareplyatyourconvenience.③Willitbeconvenientforyoutostartworktomorrow?(2)一句多譯④方便的話，我們希望你能接受我們的邀請(qǐng)。Wehopeyouwillacceptourinvitationat__your__convenience．(convenience)＝Wehopeyouwillacceptourinvitationif/when__it__is__convenient__for__you．(convenient)2．effectn．效應(yīng)；影響；結(jié)果(教材P6)effectiveadj.有效的[合作探究]體會(huì)effect的用法和意義Whileonlineshoppinghaschangedourlife,notallofitseffectshavebeenpositive.雖然網(wǎng)上購(gòu)物已經(jīng)改變了我們的生活，但它的影響并不全是積極的。Thenewtrafficrulecameintoeffect.Now,itisbeginningtotakeeffect.Ineffect，ithasaneffectonpeople’slifeinmanywaysbesidespeople’sfocusontheroadsafety.新的交通法規(guī)開始實(shí)施了。現(xiàn)在它開始生效了。實(shí)際上，除了人們對(duì)道路安全的關(guān)注外，它還在很多方面影響著人們的生活。[自主發(fā)現(xiàn)]①comeintoeffect生效，開始實(shí)施②take__effect生效，開始起作用③ineffect實(shí)際上，事實(shí)上④havea/an...effecton/upon...對(duì)……有……影響[詞塊積累]sideeffect副作用causeandeffect因果[鞏固內(nèi)化]單句語法填空①Shouldhousepropertytax(房產(chǎn)稅)comeintoeffect，Chinamightwitnessafallinhouseprices.②Optimismhasapositiveeffecton/uponpeople’sphysicalandmentalhealth,ofwhichI’mveryconvinced.③Hesaidhegraduatedfromafamousuniversity，butineffect，heneverwenttocollege.④Oneofthemosteffective(effect)waystoreducestressistotalkaboutyourfeelingswithsomeoneyoutrust.3．a(chǎn)ddictedadj.對(duì)……著迷的；沉迷的addictionn．癖好addictvt.使沉溺；使上癮n．有癮的人makesusaddictedtoit(教材P6)使我們對(duì)它上癮[合作探究]體會(huì)addict的用法和意義TeenagerswhoareaddictedtotheInternetaremorelikelytosufferfromdepression.有網(wǎng)癮的青少年更可能患憂郁癥。Hersonaddictedhimselftosmoking,whichhadabadeffectonhishealth.她的兒子吸煙上癮，這對(duì)他的健康有很壞的影響。Addictedtoplayingtheviolin,hedidn’tfindathiefwalkintohishouse.他醉心于拉小提琴，沒有注意到小偷進(jìn)屋。[自主發(fā)現(xiàn)]①be/become/getaddictedtosth/doingsth沉溺于……；專心做……②addictoneselftosth沉溺于……[鞏固內(nèi)化]一句多譯很多孩子沉迷于上網(wǎng)，因此他們對(duì)學(xué)習(xí)失去了興趣。Manykidsare/become/get__addicted__tosurfingtheNet,andsotheyhavelostinterestinstudy.＝Manykidsaddict__themselves__tosurfingtheNet,andsotheyhavelostinterestinstudy.＝Addicted__tosurfingtheNet,manykidshavelostinterestinstudy.4．a(chǎn)dmitvt.&vi.承認(rèn)；容許；接納；容納admissionn．承認(rèn)；許可Well，Iadmitit.(教材P99)好吧，我承認(rèn)。[合作探究]體會(huì)admit的用法和意義Hehadtoadmithavingmadeaseriousmistakeinpublic.他不得不當(dāng)眾承認(rèn)犯了一個(gè)嚴(yán)重的錯(cuò)誤。Ihavetoadmitthattimecanchangeeverything，includingyourfaceandyourmind.我不得不承認(rèn)，時(shí)間可以改變一切，包括你的容顏和你的想法。Theconcernedmotherbecameexcitedtohearthenewsofherson’shavingbeenadmittedtotheuniversity.擔(dān)憂的母親聽到她兒子被大學(xué)錄取的消息十分激動(dòng)。Ourfootballteamdecidedtoadmithimasoneofthemembers.我們的足球隊(duì)決定吸收他為本隊(duì)隊(duì)員。[自主發(fā)現(xiàn)]①admitdoing/having__done/that...承認(rèn)……②beadmittedto/into被接納進(jìn)入③admit...as．..接納……作為……[鞏固內(nèi)化](1)單句語法填空①LittleJackadmittedhaving__stolen(steal)intheshop,promisingthathewouldn’tdothatinfuture.②Hestudiesveryhardinordertogethimselfadmittedinto/toakeyuniversity.(2)一句多譯③他承認(rèn)無證駕駛。Headmittedhaving__drivenwithoutadrivinglicense.＝Headmittedthat__he__had__drivenwithoutadrivinglicense.Ⅰ.Listening(Ⅰ)ListentoDialogue1justonceandchoosethebestanswer.Howdoeschattingonlinemakethewomanfeel?A．Veryhappy.
