.,替代词it，that，one(s)，those用法区别,.,【学习目标】为了避免重复,it,that,one(s),those都可用来代替上文出现的名词，但它们的用法不同。现在来区别。,.,【知识概括】用法1.it代替的是前面提到的同一名称的同一事物，即同名同物。所代替的名词可以是可数名词,也可以是不可数名词。如：Thenamewhitewatercomesfromthefactthatthewaterinthesestreamsandriverslookswhitewhenitmovesquickly.（it代替不可数名词water)Andtoday,ifyougotoSaltLakeCity,youcanseeamountainwithseagullsontopofit.(it代替可数名词mountain)Idliketolookatthatatlas.MayIborrowit?(it代替可数名词atlas),.,2.one代替的是前面提到的同名异物中的任何一个,即同名异物，是泛指所代替名词是可数名词,其前可带冠词与修饰语。如代替复数名词，则用ones。如：Thepopulationproblemmaybethegreatestoneintheworldtoday.(one代替可数名词problem)-Whichjacketsareyours?-Thewhiteones.(ones代替可数名词jackets),.,3.that代替前面提到的同名异物中特指的事物，所代替的名词可以是可数名词,也可以是不可数名词，但其前通常不能有修饰语。如：those都可用来代替上文出现的名词，Thedoctorinourschoolisyoungerthanthatintheirschool.(that代替可数名词doctor)Theweatherofthisweekisworsethanthatoflastweek.(that代替不可数名词weather)Thequalityofironproducedinyourfactoryisbetterthanthatintheirfactory.(that代替不可数名词quality),.,4.those代替前面提到的同名异物中特指的事物，只能指代复数名词，相当于theones。如：InChinastudentslearnEnglishatschoolasaforeignlanguage，exceptforthoseinHongKong，wheremanypeoplespeakEnglishasafirstorasecondlanguage.(those代替复数名词students)Thecomputersinyourofficearemoreexpensivethanthoseinourschool.(those代替复数名词computers),.,区别,I.itonethat三者均可用作代词,指代前面提到的名词。一般说来,it指代同名同物;one与that则指代同名异物。Ihavelostmyumbrella;Imlookingforit.（该句中it就是指前面的myumbrella）Ihavelostmyumbrella;IthinkImustbuyone.（one在该句中表泛指,因为myumbrella已经丢了）TheumbrellayouboughtischeaperthanthatIbought.（替代词that在该句中特指“theumbrellaIbought”,以区别“theumbrellayoubought”）,.,II.one与that虽可用来指代同名异物,但one为泛指,相当于aan名词;that为特指,相当于the名词。所以one所指代的名词的修饰语一般为aansomeany;that所指代的名词的修饰语往往是thethisthat。Achairmadeofsteelisstrongerthanonemadeofwood.（该句中one可以换成achair）Thewaterinthecupishotterthanthatinthepot.（该句中that可以换成thewater）,.,III.one只能代替可数名词单数,代替可数名词复数时用ones;that既可以代替不可数名词也可以代替可数名词单数,代替可数名词复数时用those。Ilikethispenmorethanthatone.（one代替可数名词单数pen）Therewereafewyoungpeopleandsomeolderonesinthehouse.（ones代替可数名词复数people）MaryshandwritingisfarbetterthanthatofPeter.（that代替不可数名词handwriting）Thesepicturesaremorebeautifulthanthose.（those代替可数名词复数pictures）,.,IV.one既可代替事物,也可代替人,that只能代替事物而不能代替人。有时可以用theone或theones代替that或those。TheoneThatonthetableismine.（该句中Theone代替事物,并且也可以用That）Heistheteacher,theonewhoislovedbythestudents.（该句中theone代替人,不能用that）Headvisedthefarmerstochoosethebestseed-heads,theonesthosethathadthebestcolor.（该句中theones代替事物,并且也可以用those）,.,V.one一般有前置修饰语,有时也可有后置修饰语或不用修饰语。而that不能有前置修饰语,但可有后置修饰语。Cookwasastrictbutgoodcaptain,onewhotookgoodcareofhissailors.Thewaterinthewelliscleanerthanthatintheriver.,.,VI.it可以替代句中的不定式或从句等,充当形式主语或形式宾语。one与that均无此用法。Itisknowntoeverybodythatthemoontravelsaroundtheearthonceeverymonth.Ifoundithardtogetonwithher.VII.it与that均可以替代上文全句的内容或部分内容,而oneones则不可以。Hehassavedmylife;Illneverforgetit.（it代替第一分句）Tomispaintinghishouse.Iamtoldhedoesiteveryfouryears.（it代替前面分句的部分内容paintinghishouse）Letssaywemeethereatthreeoclock.Thatoughttogiveyoutimetobuyeverything.（That代替前面表述的内容）,.,可数单数用one替，ones替代复数词。不定冠词后加one，one前一般有定语。替代若系本身物，it替单they代复。比较句中替代词，不可数名词that替。最高级及序数词后，替代词常常被略去。复数名词替代词，ones与those均用之，特指ones加定冠，those之前无冠词。One(s)的定语多在前，those的定语必后置。,.,MrZhanggavethetextbookstoallthepupilsexcept_whohadalreadytakenthem.A.theonesB.onesC.someD.theothers,.,2.Ifind_easyenoughtogetonwithPam.A.thatB.thisC.oneD.it,.,3.IfIcanstophercomingtoyou,Ishalldo_.A.thoseB.whichC.theseD.it,.,4.Ihaventapen.Canyoulendme_?A.theseB.thoseC.themD.one,.,5._isnecessarythatIgetthetextofmyrevisiontyped.A.ThereB.ThisC.ThatD.It,.,6.Itook_forgranted（conj.假定;就算）thatyouwould
