本单元语法→强调句型它是英语中既特殊又实用的句型，也是高考考点中的热点，另外，如果它恰当地出现在学生的英语习作中，会给人一种“高大上”的感觉！ItisforthisreasonthatSpanishisthemainofficiallanguageofPeru.◆

原句再现◆强调句型的基本结构Itis/was+被强调部分+that/who(m)+句子其它成分※让我轻轻地告诉您：强调句型可强调的句子成分通常为主语、宾语、地点状语、时间状语等，也可以强调一个从句。但不能用来强调谓语动词，请观察以下句子原句：Imetmyoldfriendintheparkyesterday.ItwasintheparkthatImetmyoldfriendyesterday.（强调地点状语）ItwasyesterdaythatImetmyoldfriendinthepark.（强调时间状语）ItwasmyoldfriendthatImetintheparkyesterday．（强调宾语）ItwasIwho/thatmetmyoldfriendintheparkyesterday.（强调主语）a.Itwasintheparkthatwemettheforeignerthismorning．b.Itisourteachersthat／whooftenhelpus．◆在强调句型中，如果被强调的部分指人时,可用who(m)／that,其它一律用that,请观察以下句子◆在强调结构中，无论被强调的是人还是物，是单数还是复数,be动词一律用is／was，如果原句的谓语动词是一般过去时态，用was.如果原句的谓语动词是一般现在时,则用is.有时也可以用“情态动词+be”形式,请观察以下句子a.ItisTomwho/thatwinsthefirstprizeintheexam．b.Itwastheworkerswho/thatbuiltthebuildingthreeyearsago．c.ItmightbeyesterdaythatAlicecleanedtheclassroom．d.Itwillbetheteacherwhogowithyoutomorrow．

特殊疑问句：特殊疑问词+is／was+it+that+句子其余部分！特殊疑问句是对陈述句中被强调部分划线提问变来的，请观察以下句子◆

not…until…结构可用在强调句型中，其结构为：Itis／wasnotuntil…that….(句子其它成分),请观察以下句子原句：Hedidn’tcameinuntiltheclassbegan.→Itwasnotuntiltheclassbeganthathecamein．原句：Hedidn’tfinisheddoinghishomework.→ItwasnotuntillastFridaythathefinishedreadingthebook．◆当强调主语时，谓语动词应和被强调的人或物在人称和数上保持一致。如果被强调的主语是人，人称代词一般用主格，请观察以下句子a.Itis

I

who/thatam

goingtoattendthemeeting．b.Itis

who/thathelps

◆强调句型与定语从句、主语从句和状语从句的区别：一般说来，如果把句子中的Itis／was和that去掉，稍加调整语序，能还原句子，且句子意思依然完整，则为强调句型；否则，应为其他句式，请观察以下句子◆考点训练及解析

1.Itwas_______itwasrainingheavilythattheyhadtostayathomeallday．A.becauseB.sinceC.forD.since答案A.

强调句型只可以强调由because引导的原因状语从句，as／since／for引导的句子不能用在强调句中。2.Heforgets______hesawthefilm.A.thatitwaswhenB.whenitwasthat

C.whenwasitthatD.thatwasitwhen答案B.

分析：假设原句为：Hesawthefilm

whenhewasthreeyearsold．对时间状语进行强调后为：Itwaswhenhewasthreeyearsoldthathesawthefilm．再对被强调部分whenhewasthreeyearsold提问变成特殊疑问句：Whenwasitthathesawthefilm?再让特殊疑问句作宾语从句后,疑问语序就变成陈述语序:Heforgetswhenitwasthathesawthefilm.3.Itwasthetraining______hehadasayoungman______madehimsuchagoodengineer．A.what；thatB.that；whatC.that；whichD.which；that答案D.本句强调主语thetraining，而主语后又接which引导的定语从句，还原后应为：Thetrainingwhichhehadasayoungmanmadehimagoodengineer．4.Itwas_____hesaidandsomethinghedid______disappointedmeatthattime.A.what；that；thatB．that；what；that

C.what；what；thatD．what；that；what答案A.

此题的强调部分是what引导的主语从句和something，而something后带有that引导的定语从句。

5.Wasitthroughtheteacher____youcametorealizetheimportanceoflearningEnglish?A.whoB.whomC.howD.that答案为D.强调介词短语throughtheteacher，而不是名词teacher.选项A、B项具有很强的迷惑性6.Itistheyoungman____lookedfor_____caughtthemurderer．A.that;whoB.that;theyC.they;thatD.they;which答案为C.考查了定语从句和强调句型。theylookedfor前省略了关系代词that，that引导定语从句，同时又在从句中做宾语，可以省略，如果去掉定语从句，强调句为：Itistheyoungmanwho／thatcaughtthemurderer．本句意思是：是他们在寻找的那个年轻人抓住了杀人犯7.Wasitseveno'clock___youfinishedyourtask?A.whenB.thatC.then
