替代詞one,ones,that,those,it,

this,that

1)one,ones,that,thoseThat替代單數(shù)可數(shù)名詞或不可數(shù)名詞；one只替代單數(shù)可數(shù)名詞。Eg:Thevaseontheleftismorebeautifulthan__________ontheright.ThecoffeeproducedinBrazilismorefamousthan__________inMexico.

theonethat第1頁That只用于替代表達(dá)事物名詞，而one/ones替代表達(dá)人和表達(dá)事物名詞皆可。Eg:Hisyoungersisteristallerthantheelder___.Ineedtheplasticbags,notthepaper______.oneones第2頁That/those一般不帶前置定語，但必須有后置定語。One/ones都可。當(dāng)替代詞后置定語用所有格of短語或當(dāng)替代詞被所有格修飾時(shí)，不用one/ones而用thatof/thoseof.

Eg:Ilikethevasebetterthan________________inanothershop.Thewindowsofyourflatarecleanerthan_________ofmine.Agrandparent’sjobiseasierthan________ofaparent.ThecomputersinourschoolareconnectedtotheInternetwhile__________intheirschoolaren’t.theone/thatthosethatthose第3頁That/those用于替代有定冠詞名詞；one/ones用于替代有不定冠詞名詞。Eg:Thestyleofthebuildingissimilarto_________ofatemple.ACDplayermadeinJapancostsmorethan________madeinChina.thatone第4頁2)it,this和that都能夠替代前文已提到事或情況，細(xì)微差異在于it不如其他二者那么強(qiáng)調(diào)。Eg:Soshedecidedtopaintthedoorpink.______upsettheneighboursabit.Soshedecidedtopaintthehousepink._____reallyupsettheneighbours.ItThat第5頁目前面提到事物不止一件時(shí)，it一般指最先提到事物，而this/that是指最后提到事物。Eg:Wekeeptheicecreammachineinthespareroom.________ismainlyusedbythechildren.(指themachine)

Wekeeptheicecreammachineinthespareroom.____________ismainlyusedbythechildren.(指thespareroom)ItThis/That第6頁This能夠出目前它所指代事物之前；而that則指上文所提到事物。Eg:Listento________!Wewillhavethreedaysoff.“Apennysavedisapennyearned.”Whosaid_________?thisthat第7頁Eg:IboughtadictionarythreeyearsagoandIamstillusing______now.IboughtadictionarythreeyearsagobutIamgoingtobuyanew_______soon.It用以指特定前面提到過事物，即：it和它替代是同一種事物，it前無修飾語；而one用于替代與前提事物有共同之處但并不完全同樣事物，因此，one之前或之后一定有修飾語來加以區(qū)分。3)It和one

itone第8頁

It引發(fā)幾個(gè)易混同時(shí)間句型It+be+時(shí)間+since-clause

這個(gè)句型表達(dá)從since從句謂語動(dòng)作發(fā)生后來到目前或過去所通過一段時(shí)間，意為“自從......以來已多久了”

Itisthreeyearssincehisfatherpassedaway.It+be+時(shí)間+before-clause這個(gè)句型中時(shí)間一般為表達(dá)一段時(shí)間詞語(如：alongtime,months,weeks,days,hours,minutes)，主句中謂語動(dòng)詞用肯定式，意為“過多長時(shí)間才......”。主句謂語動(dòng)詞是否認(rèn)式時(shí)，意為“沒過多長時(shí)間就......”。主句時(shí)態(tài)可用過去時(shí)was或?qū)頃r(shí)willbe；用was時(shí)，before從句動(dòng)詞用一般過去時(shí)；用willbe時(shí)，before從句常用一般目前時(shí)。

第9頁她沒過多久就背會(huì)了那些詩歌。Itwas_______________shelearnedthosepoemsbyheart.過了很久警察才來。Itwas______________thepolicearrived.

要過好幾個(gè)小時(shí)他才會(huì)作出決定。It__________hoursbeforehemakesadecision.要不了幾個(gè)小時(shí)我們還會(huì)再會(huì)面。

3.It+be+時(shí)間+when-clause這個(gè)句型中,it指時(shí)間，并且表達(dá)時(shí)間詞語前沒有介詞(時(shí)間一般為詳細(xì)時(shí)間)。主句中謂語動(dòng)詞和從句中謂語動(dòng)詞在時(shí)態(tài)上一般是一致，主句是willbe，when從句用一般目前時(shí)替代將來時(shí)。Itwasalready8o‘clockwhenwegothome.Itwasthenextmorningwhenwefinishedourwork.Itwillbemidnightwhentheygetthere.

第11頁It+be+時(shí)間+that-clause

這個(gè)句型是個(gè)強(qiáng)調(diào)句型。例如：

Itwastwoyearsagothathemadeanimportantinvention.

(原句是：__________________________________)Itwasat5o’clockthathepractisedplayingtheviolininthemorning.

(原句是：________________________________)

比較：Itwas5o’clockwhenhestartedinthemorning.

(5o‘clock前沒有介詞，這是個(gè)定語從句)

Hemadeanimportantinventiontwoyearsago.Hepractisedplayingtheviolinat5o‘clockinthemorning.第12頁It+be+time+that-clause這個(gè)句型屬虛擬語調(diào)構(gòu)造，不論主句中用是is或was，that從句都須用動(dòng)詞過去式或should+動(dòng)詞原型(但不及用過去式一般)，在time之前有時(shí)可加上high或about以加強(qiáng)語調(diào)。例如：

Itistime(that)wehandedinourexercises.(=Itistimethatweshouldhandinourexercises.)

Itishightime(that)shewrotealettertoherboyfriend.第13頁It/This/That+thefirst(second,third…)time+that-clause這個(gè)句型表達(dá)截止到說話時(shí)為止某人一種經(jīng)歷，關(guān)鍵是注意time前有序數(shù)詞，主句是is時(shí)，從句要用目前完成時(shí)；假如主句用一般過去時(shí)was，則從句須對(duì)應(yīng)地用過去完成時(shí)。例如：

Thisisthefirsttime(that)theseEuropeans____________theGreatWall.

Itwasthefifthtime(that)I___________afriendlyvisittoAfrica.hadpaidhavevisited
