A.areB.isC.wasD.werehelpsam5.主謂一致問題:被強(qiáng)調(diào)的主語要和that后面的謂語動詞在數(shù)上保持一致。另外：在強(qiáng)調(diào)句型中，有時也考察用ratherthan，not…but…等連接的平行對比結(jié)構(gòu)，此時既要注重比較結(jié)構(gòu)，又要注意主謂一致，屬于較復(fù)雜的句式。常見的句式特征為：Itis/wasnot…but…that…“不是…而是…”（that后的動詞與but后的名詞或代詞保持一致）Itis/was…ratherthan…that…“是…而不是…”(that后的動詞應(yīng)與ratherthan前的名詞或代詞保持一致)如：1.Itisnothelpbutobstaclesthatmakeaman.[簡析]“使人成才的,不是助力,而是阻力”。obstacles和make形成主謂一致關(guān)系。2.PersonallyIthinkitisthesalesmanager,ratherthanthesalesgirls,______toblame.A.isB.thatisC.areD.whoareB句式特征為：Itis/was+被強(qiáng)調(diào)部分+that…，isn’t/wasn’tit？例：ItwasAliceandherboyfriendwhosenttheoldmantothehospital,______?A.dotheyB.didn’ttheyC.wasn’titD.wasit6.強(qiáng)調(diào)句型的反意疑問句形式C7.

not…until結(jié)構(gòu)的強(qiáng)調(diào)：強(qiáng)調(diào)“not…until”引導(dǎo)的時間狀語時，要用“itis/wasnotuntil…that…”結(jié)構(gòu),譯為"直到...才...".that后面的句子要用肯定式，且須用陳述句語序。

3.

Itwas________backhomeaftertheexperiment.A.notuntilmidnightdidhegoB.untilmidnightthathedidn'tgoC.notuntilmidnightthathewentD.untilmidnightwhenhedidn'tgo句式特征為:1)整個強(qiáng)調(diào)句型用作名詞性從句;或2)在強(qiáng)調(diào)句型中含有名詞性從句。8.強(qiáng)調(diào)句型和名詞性從句的結(jié)合。例：I’veforgotten____youputthepen.A.thatitwasthereB.whereitwasthatC.thatwhereitwasD.whereitwasthat[簡析]：本題是經(jīng)過變形的強(qiáng)調(diào)句型放在forgotten后作賓語從句的體現(xiàn)，為了更好地理解，我們分三步對其進(jìn)行討論。第一步，復(fù)原強(qiáng)調(diào)句，如→ItwasonthedeskthatIputthepen.第二步，對劃線部分提問→Wherewasitthatyouputthepen?第三步，將其放forgotten后作賓語從句，變?yōu)殛愂稣Z序,則變成:I’vealreadyforgottenwhereitwasthatyouputthepen.我們再看一個強(qiáng)調(diào)句型中含有同位語從句的例子：[簡析]：本題答案為D。第一個that為強(qiáng)調(diào)句型中的that；第二個that引導(dǎo)同位語從句，說明decision的內(nèi)容。Itwasattheverybeginning____Mr.Foxmadethedecision_____weshouldsendmorefirefightersthere.A.when;whichB.where;whatC.then;soD.that;that

句式特征為:在強(qiáng)調(diào)句型的被強(qiáng)調(diào)部分或其他部分中找出一個先行詞，附上修飾該部分的定語從句，這樣整個句子結(jié)構(gòu)就變得非常復(fù)雜。應(yīng)特別注意不要混淆定語從句的關(guān)系詞和強(qiáng)調(diào)句型中的that/who部分。9.強(qiáng)調(diào)句型和定語從句的結(jié)合。例1:Itwasinthesmallhouse_____wasbuiltwithstonesbyhisfather____hespenthischildhood.A.which;thatB.that;whereC.which;whichD.that;which[簡析]：本題含義為“是在這間小房子里他度過了童年”，thesmallhouse作先行詞，其后的定語從句缺做主語的關(guān)系代詞；第二空所缺的應(yīng)是強(qiáng)調(diào)句型中的結(jié)構(gòu)詞that,故答案選A。[簡析]：劃線部分作定語從句修飾先行詞time。本題中有兩個that，最大的誤會就是把二者弄混，第一個that是強(qiáng)調(diào)句型中的；第二個that是關(guān)系代詞引導(dǎo)定語從句的。因其作spent的賓語，可換成which，也可以省去。例2：Itwasplayingcomputergamesthatcosttheboyplentyoftimethatheoughttohavespentdoinghislessons.1.Itwasinthe1990s,___greatchangesweretakingplaceinchina,___hemadealotofmoney.that;whenB.duringwhich;thatC.that;thatD.that;where解析強(qiáng)調(diào)部分inthe1990s后跟了一個非限定性定語從句。練習(xí)2.Itwasintheschool,____Ioncestudied,_____weheldaparty.where;thatB.which;thatC.that;whereD.that;inwhich解析whereIoncestudied為非限定性定語從句修飾school。3.WasitBill,___playsfootballwell,___helpedtheblindmancrosstheroad.that;thatB.who;thatC.who;whoC.that;who解析Who引導(dǎo)一個非限定性定語從句修飾Bill;that指代被強(qiáng)調(diào)部分Bill.句式特征為:在一定的上下文語境中，強(qiáng)調(diào)句型的某個部分可以省略。作題時要特別注意將其復(fù)原并加以比較。1.---Whoismakingsomuchnoiseinthegarden?---_____thechildren.A.ItisB.TheyareC.ThatisD.Thereare[簡析]：強(qiáng)調(diào)句型在具體的語境中省略，其完整形式應(yīng)是：Itisthechildrenwho/thataremakingsomuchnoiseinthegarden.。10.強(qiáng)調(diào)句型的省略形式。練習(xí)2．---Hewasnearlydrownedonce.---Whenwas_______?---____wasin1998whenhewasinmiddleschool.A.that;ItB.this;ThisC.this;ItD.that;This[簡析]：第一空that指代前面他差點(diǎn)被淹死這件事。第二空的it是強(qiáng)調(diào)句的標(biāo)志詞。whenhewasinmiddleschool.為定語從句，修飾1998，其后省去了thathewasnearlydrownedonce.此題如把關(guān)系副詞when也挖空，則很容易誤選that。答案選A。3.---Wheredidyoumeethim?---Itwasinthepark____heworked.A.thatB.whereC.inwhichD.when這是個強(qiáng)調(diào)句的省略句，完整句子是：ItwasintheparkwhereheworkedthatImethim.解析三、強(qiáng)調(diào)句與其它從句的區(qū)別1）強(qiáng)調(diào)句型的判斷把itis(was)...that(who)...去掉后，（適當(dāng)調(diào)整語序）剩下的部分句意完整，不缺任何成分，那么這個句子就是強(qiáng)調(diào)句；如果句子不完整，則不是強(qiáng)調(diào)句。注意：強(qiáng)調(diào)句這一特點(diǎn)是區(qū)分強(qiáng)調(diào)句和其它從句的關(guān)鍵。ItwasyesterdaythatIboughtabook.YesterdayIboughtabook.主要從以下兩方面考慮：1)強(qiáng)調(diào)句式“Itis(was)…that/who”可去掉，不影響句意，剩下的詞能單獨(dú)組成一個完整的句子，而包含定語從句的句子不能這樣做。2)Itis(was)后，若是名詞及名詞詞組，其后一般是定語從句；若是副詞、介詞短語，則句子屬強(qiáng)調(diào)句式。2)強(qiáng)調(diào)句型與和定語從句的區(qū)別：請寫出正確的引導(dǎo)詞1)Itwas

onthefarm______wemeteachother2)Itwasthefarm_______wemeteachother.3)

onthatday_____wemeteachother.4)

(強(qiáng)調(diào)句式)(定語從句)

3)強(qiáng)調(diào)句型與主語從句的區(qū)別：強(qiáng)調(diào)句型中去掉Itbe…that后，句子仍然通順，意義也依然完整。而含主語從句的復(fù)合句中的it是指示代詞，后面多為系表結(jié)構(gòu)或被動語態(tài)。如果去掉Itbe…that，句子就不通順了。如：主語從句：Itiscertainthatheishonest.強(qiáng)調(diào)句：Itwasonthestreetthat

Isawhim.=Isawhimonthestreet

Itwas5o’clockintheafternoon_______Igothome.

Itwasat5o’clock

intheafternoon_______Igothome.whenthat

4)強(qiáng)調(diào)句型與狀語從句的區(qū)別：(狀語從句)強(qiáng)調(diào)句型:去掉Itwas…that后,剩下“Igothomeat5o’clock

intheafternoon”句子仍然通順.四、強(qiáng)調(diào)句型的形近句型Itisimportantthatwe(should)learnEnglishwell.ItisafactthatEnglishisveryimportant.ItisreportedthatEnglishisgettingmoreandmoreimportantnow.1)Itis/was+adj./n./過去分詞+that從句該句型中的It是形式主語，that引導(dǎo)的從句是真正的主語從句。如：Itistwomonthssincehefellill.他病了兩個月了。Itistwomonthssincehewasill.他病好已經(jīng)兩個2)Itis/hasbeen+時間段+since從句如果since和延續(xù)性動詞連用，則意為“某人不做某事已有多久了”；如和短暫動詞連用，則為“某人做某事已有多久了”。如：3)Itwas/willbe+時間段+before從句表示“……多久后才...”。Itwasalongtimebeforetheymetagain.很長時間后他們才再次見面。Itwillbealongtimebeforetheymeetagain.要過很久后他們才會再見面。Itwas1949whenthePeople'sRepublicofChinawasfounded.4）Itbe+時間點(diǎn)+when從句表示“某事發(fā)生時正是……時候”試比較強(qiáng)調(diào)句型句：Itwasin1949thatthePeople'sRepublicofChinawasfounded.(去掉it，was，that后仍是一個完整的句子)Wasitonalonelyisland______hewassavedonemonthaftertheboatwentdown?where B.that C.whichD.what2.Itisnothowmuchwedobuthowmuchloveweputintowhatwedo______benefitsourworkmost.who B.which C.that D.what3.ItwasnotuntilIcamehere_____Irealizedthisplacewasfamousfornotonlyitsbeautybutalsoitsweather.A.who B.thatC.where
