Unit1WhatcanIdoforyou?that和which做比較，主要在于它們在定語從句中的用法that和which在定語從句中都是做關(guān)系代詞，指代先行詞是事物的名詞或代詞（that還可以指代人，which不可以）。通常情況下二者可以互換。區(qū)別：關(guān)系代詞用that（不用which）的情況：1.先行詞是all,anything,everything,nothing等,關(guān)系代詞應(yīng)用thatThat'sallthathetoldme.2.先行詞前有theonly,thesame,thevery或no,little,much,any,every,all等修飾時(shí),關(guān)系代詞應(yīng)用thatSheistheonlypersonthatIknowinthiscompany.3.先行詞前有序數(shù)詞或形容詞最高級修飾時(shí),關(guān)系代詞常用thatThefirstthingthatIwanttodoistotakeitaway.4.當(dāng)先行詞同時(shí)含有"人"或"物"時(shí),關(guān)系代詞應(yīng)用that5.在固定結(jié)構(gòu)thesame...that...;so...that...;such...that...以及itis/was...that...的強(qiáng)調(diào)句型中,要用thatThisisthesameparkthatweoncevisited.6.如主句以therebe開頭時(shí),關(guān)系代詞應(yīng)用thatThereisaroomthathastwowindows.關(guān)系代詞用which（不用that）的情況：1.非限制性定語從句中關(guān)系代詞一般要用whichShewonthecompetition,whichmadethewholefamilyveryhappy.2.關(guān)系代詞前如有介詞,關(guān)系代詞須用which;如把介詞移至句末,可用that(或省略)There’sonlyoneproblemaboutwhichtheydisagree.Thisisthekey(that)shewaslookingfor.3.如果先行詞是that,關(guān)系代詞應(yīng)用whichIknowthatwhichyoutoldme.4.如先行詞和定語從句之間被其它較長的成分分隔,常用whichTomtoldherthestoryoftheyoungairmanwhichInarratedatthebeginningofthisbook.(先行詞為story)5.在"those+復(fù)數(shù)形式的名詞"結(jié)構(gòu)中,其后的關(guān)系代詞多用whichAshopshouldkeepastockofthosegoodswhichsellbest.6.一個(gè)句子中如有兩個(gè)定語從句,第一個(gè)定語從句用了關(guān)系代詞that,第二個(gè)從句中的關(guān)系代詞宜用which;但在平行結(jié)構(gòu)中,應(yīng)重復(fù)同一個(gè)關(guān)系代詞Thisisthebookthatyouboughtwhichyouhavelost.Ihaveahousewhichislocatedonthehillside,whichfacesthesouth.此外，that還可引導(dǎo)同位語從句,which不能Ihaveheardthenewsthattheyhadwonthegame.專項(xiàng)訓(xùn)練
