94强调句型

强调句型强调句型Itis/was...who/that的用法及注意事项一、强调句型的用法在英语中，我们常用Itis／was…who/that结构来突出强调句子的某一成分(一般是句子中主语，宾语或状语)。在这个句型中，it没有词汇意义，只是引出被强调的成分。如果被强调的成分是表示人的词，用who或that来连接都可以。如果是其它成分，则一律用that来连接。e.g.Itismymotherwho／thatcookseveryday.e.g.ItwasyesterdaythatTompassedinthemathsexam．二、使用本句型的几个注意事项1．被强调成分是主语，who／that之后的谓语动词应该在人称和数上与原句中的主语保持一致。e.g.ItisIwhoamright．e.g.Itishewhoiswrong．e.g.Itisthestudentswhoarelovely．2．即使被强调成分是句子中的时间状语，地点状语，原因状语等，也不能用when，where,because，要用that。e.g.ItwasafterthewarwasoverthatEinsteinwasabletocomebacktohisresearchworkagain.e.g.Itwasinfrontofthebankthattheoldladywasrobbed．e.g.Itwasbecauseoftheheavyrainthathecamelate．3．如果被强调的成分有同位语，同位语也应提前。Itwasfromhim，hischemistryteacher，thatPaullearnedtowatchcarefullyinclass．4．被强调成分是作主语的代词，用主格，是作宾语的代词，用宾格。Itwashethathelpedmeyesterday.Itwasmethathehelpedyesterday.5．被强调部分既包括人又包括物，用that不用wholtwasthethingsandpeoplethattheyrememberedthattheyweretalkingabout．三、考试中，为了增加试题难度，强调句型经常以疑问句形式出现。其一般疑问句形式是：Is／Wasit+被强调成分+who／thatIsitMr.SmithwhoteachesyouEnglish?其特殊疑问句形式是：疑问词+is／was+被强调成分+that...Whywasitthatyoudidnotattendthemeetingyesterday?Whenwasitthatthistrafficaccidenthappen?WherewasitthatyouputmyEnglishdictionary?四、区分定语从句和强调句型.某些定语从句和强调句型形式差不多，容易混淆。如果去掉itis／was...that句子仍然通顺成立，则为强调句型，不成立不通顺，则为定语从句。e.g.ItwasthreeyearsagothathewenttoAmericaforafurtherstudy.去掉Itwasthat句子为ThreeyearsagohewenttoAmericaforafurtherstudy．句子通顺，意思完整，那么，这就是一个强调句型。PracticeNancysawyoursisterinTokyolastweek.ItwasNancywhosawyoursisterinTokyolastweek.ItwasyoursisterwhomNancysawinTokyolastweek.ItwasinTokyothatNancysawyoursisterlastweek.ItwaslastweekthatNancysawyoursisterinTokyo.Ex:把下列句子改为强调句：1.Petersawhisfriendintheparkyesterday.2.Ididn’treceivemyletteruntilyesterday?4.Didithappenin1980?5.WhydoeseveryonethinkI’mnarrow-minded?1.Petersawhisfriendintheparkyesterday.ItwasPeterwhosawhisfriendintheparkyesterday.ItwashisfriendwhomPetersawintheparkyesterday.ItwasintheparkthatPetersawhisfriendyesterday.ItwasyesterdaythatPetersawhisfriendinthepark.2.Ididn’treceivemyletteruntilyesterday?Itwasn’tuntilyesterdaythatIreceivedmyletter.4.Didithappenin1980?Wasitin1980thatithappened?5.WhydoeseveryonethinkI’mnarrow-minded?WhyisitthateveryonethinksI’mnarrow-minded?有些否定句也可以改成这种强调结构：Ididn’thearfromheruntillastsummer.Itwasn’tuntillastsummerthatIheardfromher.Ididn’tdoallthisformyself.Itwasn’tformyselfthatIdidallthis.问句也可变成这种结构：Whocalledhim“comrade”?Whowasitthatcalledhim“comrade”?Howdidyouforgettolockthedoor?Howwasitthatyouforgottolockthedoor?使用强调句型应注意以下几点：强调句的谓语is或was永远用单数，其中is既可强调现在的情况，也可强调过去的情况，was只能强调过去的情况。例如：Itis/wasyesterdaythatImetyourfatherinthestreet.不管被强调部分是哪种状语，只能用that连接，不得使用where,when等连词。例如：ItwasinthestreetthatImetyourfatheryesterday.被强调部分为人时，可用who（主格或宾格）和whom（宾格）代替that，用that也行。例如：Itwasyourfatherthat/whom/whoImetinthestreetyesterday.强调句中也要注意主谓一致、人称一致和否定转移的问题。例如：Itistheywhoareourfriends.Itwasnotuntilteno’clockthatwegothomelastnight.注意不要混淆强调句和其他从句。Itis/was---that---为强调句标志，去掉后仍可组成一个完整的句子，只是没有被强调，而其他从句一般不具备这一特征。比较：Itwasteno’clockwhenwegothomelastnight.我们昨晚到家时已十点了。Itwasatteno’clockthatwegothomelastnight.我们昨晚是在十点到家的。第一句不是强调句，when不可改为that，因为去掉itwas和that后，只能组成“Wegothometeno’clocklastnight”这是一个不完整的句子；第二句是强调句，因为去掉itwas和that后，能组成“Wegothomeatteno’clocklastnight”这是一个完整的句子,that不可改为when。注意不要混淆强调句和其他从句。1.去掉“itis/was及关联词”，在不添词、不减词的前提下能重新排列成一个完整的句子，则是强调句型，关联词用that（被强调部分是人也可用who/whom）。2.如果不是强调句型，则分析表时间的短语是时间段还是时间点，是时间点则用关联词when。It+be+(时间点)+when…此句型中,when引导的是状语从句,常用一般过去时.表示“当…发生时,时间是…”3.如果是时间段，则看从句发生的动作在该时间段之前还是之后，之前则选since，在之后则选before；或就如下句型进行记忆：Itis+时间段+sinceSince从句是瞬间动词:“自从…以来多长时间”Since从句是延续动词:“自从…不以来多长时间”Itwillbe/is+时间段+before“再过多久某事才发生”Itwas+时间段+before“过了多久某事才发生某事”4.Itis/wasthefirst/secondtime(+that)…此句型中time(次)前常用序数词,that从句用完成时态5.It+be+(high)time+that…(should)+do/did要用虚拟语气,“该做某事了”eg.Itis6yearssinceIbegantolearnEnglish.Itis5yearssinceIworkedinthefactory.It’llbetwoyearsbeforetheprojectiscompleted.ItwasOct.1,1949whennewchinacameintobeing.Itwasnotuntillastnightthathemadeuphismind.ThisisthefirsttimethatIhavebeenhere.Itistimethatyouwenthome.Itwastenmonthsbeforehedesignedthebridge.Practice:1.ItwasonlywhenIrereadhispoemsrecently___Ibegantoappreciatetheirbeauty.A.untilB.thatC.thenD.so2.Itwasabout600yearsago_____thefirstclockwithafaceandanhourhandwasmade.A.thatB.untilC.beforeD.when3.Itwasnotuntil1920_____regularbroadcastbegan.A.whileB.whichC.thatD.since4.Itwasmidnight_____myfathercamebackfromwork.A.whenB.whileC.beforeD.that5.It’llbemanyyears_____thechemicalsstarttoescapefromthecontainers.A.sinceB.thatC.whenD.beforeBACADwith复合结构with复合结构是学生学习英语时经常接触的句型，也是高考考查的热点1.with复合结构的构成with+宾语+宾语补足语，构成with复合结构，宾语可以是名词或是代词，宾语补足语可以是介词短语、过去分词、现在分词、形容词、动词不定式、副词。且with后面的宾语与其后的宾语补足语有逻辑上的主谓关系。1）With+宾语+介词短语Hewasasleepwithhisheadonhisarms.2）with+宾语+过去分词（宾语与宾补之间是被动关系）Alltheafternoonheworkedwiththedoorlocked.Helayinbedwithhisheadcovered.3）with+宾语+现在分词（宾语与宾补之间是主动关系）Withwintercomingon，it'stimetobuywarmclothes.4）with+宾语+todo（不定式做宾补有“将来”的含义）Ican'tgooutwithallthesedishestowash.5）with+宾语+形容词/副词WithJohnaway，we'vegotmoreroom.Andersonwaslyingonthebedwi
