訪問次數(shù)：863眾所周知，which與as都可以引導(dǎo)定語從句，但它們有許多用法上的區(qū)別，現(xiàn)就此簡(jiǎn)要分析如下：一、which與as引導(dǎo)非限制性定語從句的區(qū)別：1．Which只能放在主句后面，而as引導(dǎo)的從句位置相對(duì)較靈活，可在前，可在中，也可在后。例如：A)

Asherealized,Iwasveryusefultohim.(在前)B)

Air,asweknow,isagas.（在中）C)

Hewasaforeigner,asIknowfromhisaccent.(在后)2.在which引導(dǎo)的定語從句中，謂語動(dòng)詞若是am,is,are則這些系動(dòng)詞不能省略；而as后面若是這種情況，則可以省略。例如：A)

Heisateacher,as(is)clearfromhismanner.(is可以省略)B)

Hesaidhehadneverseenherbefore,whichwasnottrue.(was不可省略)3.當(dāng)which引導(dǎo)的從句在意義上近乎并列關(guān)系時(shí)，可以用andthis，andthat代替，意思是“這件事”例如：A)

Hechangedhismind,which(andthis,andthat)mademeveryangry.他改變了主意，這使我很生氣。B)

Shehasmarriedagain,which(=andthis,andthat)wasunexpected.出乎意料的是，她又結(jié)婚了。而as主要起與上下文連接的作用，表達(dá)說話人的看法、觀點(diǎn)，并指出主句內(nèi)容的出處或根據(jù)等，例如：C）Einstein,asweknow,isafamousscientist.愛因斯坦，眾所周知，是位偉大的科學(xué)家。D）Asisannouncedintoday’snewspaper,wemustimproveourstyleofwork.今天的報(bào)紙上說，我們必須改進(jìn)工作作風(fēng)。4．作主語時(shí)，which既可以作系動(dòng)詞be的主語，也可以作實(shí)義動(dòng)詞的主語；而這時(shí)as只可以做系動(dòng)詞be的主語。例如：A)

Hemarriedher,whichwasnatural.（可用as代替which）他和她結(jié)婚，這是很自然的事。B)

Hewona/theNobelPrizeinchemistry,whichmadehimillustrious.(不可用as代替which)他獲得了諾貝爾化學(xué)獎(jiǎng)，這使他名揚(yáng)天下。5．當(dāng)定語從句位于主句之后，純粹表示主句所述內(nèi)容，不帶有“如……那樣”的意思時(shí)，往往用which,而不用as。例如：A)

Theywereinvitedtothestatebanquet,which(as)wasagreathonortothem.他們被邀請(qǐng)參加國宴，這對(duì)他們來說是莫大的榮幸。B)

Wehadtosleepinourwetclothes,whichwasmostuncomfortable.我們不得不穿著濕衣服睡覺，這簡(jiǎn)直太不舒服了。C)

Mummyalwaystreatsmejustlikeababy,whichIcan’tbear.媽媽老把我當(dāng)成小孩對(duì)待，這讓我無法忍受。6．當(dāng)定語從句有“如同……那樣”含義時(shí)，用as比用which更常見，而這些從句幾乎成為固定說法。例如：A)

Thingswillturnoutcontrarytoone’swishes,asisoftenthecase.事與愿違，這是常用的事。B)

Aswasnatural,thisinordinatehopewasfollowedbyanexcessivedepression.這種過分希望之后，接著是極度的沮喪，是很自然的事。C)

Chaucerisburiedin“poet’sCorner”,asmighthavebeenexpected.正如人們已經(jīng)預(yù)料的，喬叟被葬在“詩人角”。D)

Thematerialiselastic,asisshowninthefigure.這種霉?fàn)€有彈性，如圖所示。E)

Asweknow(眾所周知)F)

Ashasbeensaidabove/before（正如前文所述）G)

Ashasbeenpointedout（正如已經(jīng)指出的）H)

Asmightbeimagined（可以想象得到）7．當(dāng)定語從句的關(guān)系代詞指的是先行詞本身時(shí)，只能用which。例如：A)

Theseappletrees,whichIplantedthreeyearsago,havenotborneanyfruit.這些蘋果樹是我三年前種下的，沒結(jié)出任何果實(shí)。B)

TheThames,whichisnowcleanenoughtoswimin,waspollutedforoverahundredyears.泰晤士河，現(xiàn)在已經(jīng)干凈，可以在里面游泳，它曾被污染了一百多年。8．帶介詞的典型的定語從句，必須用which，不能用as。例如：A)

Thereisagreatdealofoxygenaroundus,withoutwhichwecouldnotlive.我們周圍有許多氧氣，沒有它我們就無法生存。B)

Theshedinourgarden,inwhichweoftenplayed,haslastedforalongtime.我們經(jīng)常玩耍的花園里的那個(gè)棚子，已經(jīng)有很長時(shí)間了。二、引導(dǎo)限制定語從句時(shí)which與as的區(qū)別：1．先行詞如為表示物的名詞或代詞，在從句中又做介詞的賓語時(shí)，只能用which。例如：ThisisthepaninwhichIboiledthemilk.這就是我煮牛奶的鍋。2．前面有as時(shí)，引導(dǎo)定語從句的關(guān)系代詞用as,不用which。例如：Thereareasmanydictionariesasareneeded.所需要的字典都有了。3．前面有such時(shí)，引導(dǎo)定語從句的關(guān)系代詞用as，不用which。1）SuchwomenasknowTomthoughthewascharming.認(rèn)識(shí)湯姆的女人都認(rèn)為他很迷人。2）Ihaveneverheardsuchstoriesashetells.他講的那些故事我從沒有聽過。3）HeisnotsuchamanasIexpected.他不是我期望的那種人。1．

前面有thesame時(shí)，引導(dǎo)定語從句的關(guān)系代詞用as而不用which。例如：1）Wearefacingthesameproblemsaswedidyearsago.我們現(xiàn)面臨著和多年以前同樣的困難。2）ThisisthesamewalletasIlost.這只錢夾子與我丟失的那只相同。3）Ihavethesametroubleasyouhave.我和你有著同樣的困難。總之，which與as引導(dǎo)定語從句的區(qū)別要在實(shí)踐中多體會(huì)，體會(huì)多了，才能正確運(yùn)用。

在定語從句中，一般的從句關(guān)系代詞是which、who、whom、that、whose,其代替主句中的人或物，在從句中做主語、賓語或定語。而學(xué)生在學(xué)習(xí)過程中，常會(huì)遇到as作為關(guān)系代詞出現(xiàn)，做起題來，無從下手,就此筆者對(duì)as作為關(guān)系代詞引導(dǎo)定語從句的情況做一歸納,以供參考.一、as引導(dǎo)限制性定語從句主要結(jié)構(gòu)有：thesame…asas…assuch…asso…as主句中出現(xiàn)thesame,as,such,so修飾先行詞，需選擇as做關(guān)系代詞在定語從句中做主語或賓語。

Grammar,ashasbeensaidbefore,isnotasetofdeadrules.語法，就像以前所說，不是一套死規(guī)則。2.

Asisknowntoall,TaiWanispartofChina.⑶

as引導(dǎo)非限制性定語從句，有“如，似，正像”的含義，因此，下列句式多用asashasbeensaidabove如上所說asanybodycansee正像每個(gè)人所看到的那樣aswehadexpected正如我們所預(yù)料的那樣1.

Thingsarenotalwaysastheyappear.事情并不一直像他們表面那樣。2.
