PAGEUnit4GlobalwarmingSectionⅢGrammar——it的用法(Ⅱ)一、it引導(dǎo)強(qiáng)調(diào)句型1．強(qiáng)調(diào)句型的基本結(jié)構(gòu)：Itis/was＋被強(qiáng)調(diào)部分＋that/who＋其他成分(1)此結(jié)構(gòu)中it沒有詳細(xì)意義，只是引出被強(qiáng)調(diào)部分。(2)此強(qiáng)調(diào)句型只能強(qiáng)調(diào)主語、賓語、狀語，不能強(qiáng)調(diào)謂語。(3)強(qiáng)調(diào)時間狀語、地點狀語、緣由狀語等時要用that而不能用when,where,because。(4)被強(qiáng)調(diào)的成分是表示人的詞時用who/that，而被強(qiáng)調(diào)部分是物時只能用that。如：Itismymotherthat/whoremindsmetogetupontimeeveryday.每天都是我媽媽提示我按時起床。ItwasMrSmithwho/that/whomheturnedtoforhelp.他是向史密斯先生求助的。ItwasinthemuseumthatIfirstsawthisoldancientvase.我是在博物館里第一次見到這個古花瓶的。ItiseverySundaythattheygettogethertohaveagoodtime.每個星期天他們聚在一起來度過開心的時間。ItwasbytrainthattheytravelledtoTibetlastsummer.去年夏天他們乘火車去了西藏。2．強(qiáng)調(diào)句型的時態(tài)：(1)假如原句中謂語動詞的時態(tài)是現(xiàn)在或?qū)頃r間范疇的時態(tài)(如一般現(xiàn)在時、現(xiàn)在進(jìn)行時、現(xiàn)在完成時、現(xiàn)在完成進(jìn)行時、一般將來時、將來進(jìn)行時、將來完成時等)，強(qiáng)調(diào)句型的時態(tài)為Itis＋被強(qiáng)調(diào)部分＋that/who＋其他成分。(2)假如原句中謂語動詞為過去時間范疇的時態(tài)(如一般過去時、過去進(jìn)行時、過去完成時、過去將來時等)，強(qiáng)調(diào)句型的時態(tài)為Itwas＋被強(qiáng)調(diào)部分＋that/who＋其他成分。如：Ameetingwillbeheldnextweekinthemeetingroom.→Itisnextweekthatameetingwillbeheldinthemeetingroom.Wegotoworkeverydaybybus.→Itisbybusthatwegotoworkeveryday.Thecouplehavegotseparatedfromeachotherrecently.→Itisrecentlythatthecouplehavegotseparatedfromeachother.Theyboughtanexpensiveapartmenttheotherday.→Itwastheotherdaythattheyboughtanexpensiveapartment.Whentheyarrivedattheairport,theplanehadalreadyleft.→Itwaswhentheyarrivedattheairportthattheplanehadalreadyleft.3．強(qiáng)調(diào)句型的疑問形式：(1)強(qiáng)調(diào)句型的一般疑問句：Is/Wasit＋被強(qiáng)調(diào)部分＋that/who＋其他成分？(2)強(qiáng)調(diào)句型的特別疑問句：特別疑問詞＋is/wasit＋that/who＋其他成分？如：Isitinthedininghallthattheywillholdaparty?他們將在這家餐廳實行宴會嗎？IsitProfessorLiwhowillcometoourschooltogiveusaspeech?是李教授要來我們學(xué)校給我們做演講嗎？Wasitlastmonththattheyhadanimportantexamination?他們是上個月進(jìn)行了一次重要考試嗎？WhenisitthattheyaregoingtoleaveforParis?他們準(zhǔn)備何時動身去巴黎？Howwasitthattheygottothetopofthathighmountain?他們是如何到達(dá)那座高山的山頂?shù)模?．not...until...在強(qiáng)調(diào)句型中的運(yùn)用：當(dāng)被強(qiáng)調(diào)的是not...until句型時，應(yīng)將not與until部分一起進(jìn)行強(qiáng)調(diào)，即構(gòu)成“Itis/wasnotuntil...that...”結(jié)構(gòu)。由于not已經(jīng)前移，that后應(yīng)用確定句式。如：Hedidn'tcomebackuntilthenextyear.→Itwasnotuntilthenextyearthathecameback.Theywillnotleavehereuntiltheyfinishtheproject.→Itisnotuntiltheyfinishtheprojectthattheywillleavehere.[巧學(xué)助記]強(qiáng)調(diào)結(jié)構(gòu)記憶口訣it強(qiáng)調(diào)并不難，that總是在中間。除了謂語不用管，主、賓、表、狀都提前。否定轉(zhuǎn)移必考題，否定強(qiáng)調(diào)難為你。疑問強(qiáng)調(diào)莫忽視，高考場上要牢記。[深化點撥]強(qiáng)調(diào)句型的幾個留意事項：(1)在強(qiáng)調(diào)句型中，若強(qiáng)調(diào)原句中的主語，that/who后的謂語動詞的單復(fù)數(shù)應(yīng)與被強(qiáng)調(diào)的主語的單復(fù)數(shù)形式一樣。如：Thelittleboyhasbrokenawindowoftheoldlady.→Itisthelittleboywho/thathasbrokenawindowoftheoldlady.Hisfriendsareplanningtoattendhispartytobeheldtomorrow.→Itishisfriendsthat/whoareplanningtoattendhispartytobeheldtomorrow.(2)強(qiáng)調(diào)句型的特別疑問形式用于主從復(fù)合句中的名詞性從句時，其語序應(yīng)用陳述語序。如：Whatisitthattheywilldonext?→Doyouknowwhatitisthattheywilldonext?Whywasitthattheywenttothatvillagelastweek?→Canyoutellmewhyitwasthattheywenttothatvillagelastweek?(3)強(qiáng)調(diào)句型與定語從句相結(jié)合，若強(qiáng)調(diào)句型中的被強(qiáng)調(diào)部分含有定語從句，留意要對定語從句引導(dǎo)詞及強(qiáng)調(diào)句型中的that做出正確的推斷。如：Itwaslastspringwhentheyworkedtogetherthattheybecamegoodfriends.(when引導(dǎo)定語從句)正是在他們一起工作的去年的春天里，他們成了好摯友。Itwasintheschoolwheretheyhadtheirschoolingthattheyhadaget-togetheragaintwentyyearslater.(where引導(dǎo)定語從句)正是在他們曾接受教化的學(xué)校里，他們20年后又聚在了一起。二、it的習(xí)慣用法1．it的習(xí)慣用語(1)Howisitwithyourstudy?你的學(xué)習(xí)怎么樣？(2)Wemustfightitout.我們必需奮戰(zhàn)究竟。(3)Ican'thelpit.我沒有方法。(4)Itwenthardwithhim.他身遭不幸。(5)Itisalloverwithme.我完蛋了。(6)Yougotit!你猜對了！/你答對了！(7)Thankyou！Icanmanageit.感謝你！我能行。(8)Ihopewecanmakeit.我希望我們能勝利。2．it指代時間的常用句型(1)Itbe＋時間段＋since...如：Itisfiveyearssincehelefthere.他離開這兒已有5年了。Itisfiveyearssinceshegraduated.她畢業(yè)已經(jīng)5年了。(2)Itbe＋時間段＋before...如：ItwassometimebeforeIrealizedthetruth.過了一段時間我才了解到真相。(3)Itis/was＋時間＋when定語從句。如：Itwasmidnightwhenwegothome.我們到家時已是半夜。Ⅰ.句型轉(zhuǎn)換(強(qiáng)調(diào)下列各句中的黑體部分)1．Havetheydecidedtogiveuptheirchancetoworkforthecompany?→Isittheirchancetoworkforthecompanythattheyhavedecidedtogiveup?2．Notwhatyousaidbutwhatyoudidmattersmuch.→Itisnotwhatyousaidbutwhatyoudidthatmattersmuch.3．Wheredidthepolicefindtheirmissingchild?→Wherewasitthatthepolicefoundtheirmissingchild?4．Theydidn'tleavetotraveluntiltheyfinishedthework.→Itwasnotuntiltheyfinishedtheworkthattheylefttotravel.5．Inthecitywheretheyspenttheirholiday,theyhadaquarrelforthefirsttime.→Itwasinthecitywheretheyspenttheirholidaythattheyhadaquarrelforthefirsttime.Ⅱ.在句中空白處填入1個適當(dāng)?shù)膯卧~1．Itisnotwhoisrightbutwhatisrightthatisofimportance.2．Ijustwonderwhatitisthatmakeshimsoexcited.3．ItwasalongtheMississippiRiverthatMarkTwainspentmuchofhischildhood.4．—I'ver
