②關(guān)系代詞有that,which,who,whom,whose,as等；關(guān)系副詞有when,where,why等。

③作用：引導(dǎo)定語(yǔ)從句；代替先行詞；在定語(yǔ)從句中擔(dān)當(dāng)一個(gè)成分。e.g.Thefish

that/which

comefromtherivercan’t

liveinthesea.（先行詞）（關(guān)系代詞）Theworkers

that/whoworkveryhardcangetmoremoney.（先行詞）（關(guān)系代詞）

④先行詞表人用who/that,主語(yǔ)，賓語(yǔ)，表語(yǔ).先行詞表物用which/that,主語(yǔ)，賓語(yǔ)，表語(yǔ).先行詞表人或物的，用whose,即whose+n.

先行詞表時(shí)間用when,狀語(yǔ)先行詞表地點(diǎn)用where,狀語(yǔ)先行詞表原因用why,狀語(yǔ)

▲.1.當(dāng)關(guān)系代詞在從句中作主語(yǔ)時(shí)不能省略，作賓語(yǔ)時(shí)則可以省略.2.當(dāng)先行詞被序數(shù)詞、形容詞最高級(jí)修飾或是不定代詞或既有人又有物時(shí)，關(guān)系代詞只能用that，而不能用which.e.g.Thisisthebest

film

thatIhaveseen.3.關(guān)系代詞在定語(yǔ)從句中作主語(yǔ)時(shí)，從句的謂語(yǔ)動(dòng)詞的人稱和數(shù)須和先行詞一致。e.g.I

sofar修飾謂語(yǔ)動(dòng)詞且表示一直持續(xù)到現(xiàn)在時(shí)，謂語(yǔ)動(dòng)詞通常要用現(xiàn)在完成時(shí)。eg.Sofartherehasbeennobadnews.到現(xiàn)在為止還沒(méi)有什么壞消息。Sofar50peoplehavediedinthefighting.

到現(xiàn)在為止，已有50人在戰(zhàn)斗中喪生。(3)表示“僅到一定程度”“僅在有限的范圍內(nèi)”，此時(shí)句子謂語(yǔ)動(dòng)詞也需要根據(jù)具體語(yǔ)境來(lái)確定時(shí)態(tài)。eg.Icanonlyhelphimsofar.我只能幫他到這種程度。Languagepoints2.
