原句再現◆強調句型的基本結構Itis/was+被強調部分+that/who(m)+句子其它成分※讓我輕輕地告訴您：強調句型可強調的句子成分通常為主語、賓語、地點狀語、時間狀語等，也可以強調一個從句。但不能用來強調謂語動詞，請觀察以下句子原句：Imetmyoldfriendintheparkyesterday.ItwasintheparkthatImetmyoldfriendyesterday.（強調地點狀語）ItwasyesterdaythatImetmyoldfriendinthepark.（強調時間狀語）ItwasmyoldfriendthatImetintheparkyesterday．（強調賓語）ItwasIwho/thatmetmyoldfriendintheparkyesterday.（強調主語）a.Itwasintheparkthatwemettheforeignerthismorning．b.Itisourteachersthat／whooftenhelpus．◆在強調句型中，如果被強調的部分指人時,可用who(m)／that,其它一律用that,請觀察以下句子◆在強調結構中，無論被強調的是人還是物，是單數還是復數,be動詞一律用is／was，如果原句的謂語動詞是一般過去時態(tài)，用was.如果原句的謂語動詞是一般現在時,則用is.有時也可以用“情態(tài)動詞+be”形式,請觀察以下句子a.ItisTomwho/thatwinsthefirstprizeintheexam．b.Itwastheworkerswho/thatbuiltthebuildingthreeyearsago．c.ItmightbeyesterdaythatAlicecleanedtheclassroom．d.Itwillbetheteacherwhogowithyoutomorrow．

特殊疑問句：特殊疑問詞+is／was+it+that+句子其余部分！特殊疑問句是對陳述句中被強調部分劃線提問變來的，請觀察以下句子◆

not…until…結構可用在強調句型中，其結構為：Itis／wasnotuntil…that….(句子其它成分),請觀察以下句子原句：Hedidn’tcameinuntiltheclassbegan.→Itwasnotuntiltheclassbeganthathecamein．原句：Hedidn’tfinisheddoinghishomework.→ItwasnotuntillastFridaythathefinishedreadingthebook．◆當強調主語時，謂語動詞應和被強調的人或物在人稱和數上保持一致。如果被強調的主語是人，人稱代詞一般用主格，請觀察以下句子a.Itis

I

who/thatam

goingtoattendthemeeting．b.Itis

myteacher

who/thathelps

◆強調句型與定語從句、主語從句和狀語從句的區(qū)別：一般說來，如果把句子中的Itis／was和that去掉，稍加調整語序，能還原句子，且句子意思依然完整，則為強調句型；否則，應為其他句式，請觀察以下句子◆考點訓練及解析

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

強調句型只可以強調由because引導的原因狀語從句，as／since／for引導的句子不能用在強調句中。2.Heforgets______hesawthefilm.A.thatitwaswhenB.whenitwasthat

C.whenwasitthatD.thatwasitwhen答案B.

分析：假設原句為：Hesawthefilm

whenhewasthreeyearsold．對時間狀語進行強調后為：Itwaswhenhewasthreeyearsoldthathesawthefilm．再對被強調部分whenhewasthreeyearsold提問變成特殊疑問句：Whenwasitthathesawthefilm?再讓特殊疑問句作賓語從句后,疑問語序就變成陳述語序:Heforgetswhenitwasthathesawthefilm.3.Itwasthetraining______hehadasayoungman______madehimsuchagoodengineer．A.what；thatB.that；whatC.that；whichD.which；that答案D.本句強調主語thetraining，而主語后又接which引導的定語從句，還原后應為：Thetrainingwhichhehadasayoungmanmadehimagoodengineer．4.Itwas_____hesaidandsomethinghedid______disappointedmeatthattime.A.what；that；thatB．that；what；that

C.what；what；thatD．what；that；what答案A.

此題的強調部分是what引導的主語從句和something，而something后帶有that引導的定語從句。

5.Wasitthroughtheteacher____youcametorealizetheimportanceoflearningEnglish?A.whoB.whomC.howD.that答案為D.強調介詞短語throughtheteacher，而不是名詞teacher.選項A、B項具有很強的迷惑性6.Itistheyoungman____lookedfor_____caughtthemurderer．A.that;whoB.that;theyC.they;thatD.they;which答案為C.考查了定語從句和強調句型。theylookedfor前省略了關系代詞that，that引導定語從句，同時又在從句中做賓語，可以省略，如果去掉定語從句，強調句為：Itistheyoungmanwho／thatcaughtthemurderer．本句意思是：是他們在尋找的那個年輕人抓住了殺人犯7.Wasitseveno'clock___youfinishedyourtask?A.whenB.thatC.then
