先行詞:被修飾的名詞或代詞關(guān)系詞：1.連接從句；2.替代先行詞；3.在從句中充當(dāng)主語、賓語或者狀語。定語從句2.用法被定語從句限定的詞叫做先行詞,引導(dǎo)定語從句的詞叫做引導(dǎo)詞，分別是關(guān)系代詞和關(guān)系副詞;其中which,that,who,whom,whose,為關(guān)系代詞。關(guān)系代詞指代人：whowhomthat

指代事物：whichthat指代所屬關(guān)系：whose關(guān)系副詞wherewhenwhy1.ThisisthehousewhereIlived20yearsago.2.Istillremembertheday

引導(dǎo)定語從句的關(guān)系詞在從句中作時間狀語，可使用關(guān)系副詞when來引導(dǎo)，也可用“介詞+which”來引導(dǎo)，介詞可使用in/on/at/during…Thewavessooncarriedmetoanareawheretheotherfishermenwere.先行詞關(guān)系副詞Thewavessooncarriedmetoanarea.Theotherfishermenwereinthearea.Thewavessooncarriedmetoanareainwhichtheotherfishermenwere.引導(dǎo)定語從句的關(guān)系詞在從句中作地點狀語，可使用關(guān)系副詞where來引導(dǎo)，也可用“介詞+which”來引導(dǎo)，介詞可使用in/on/at/under/…地點地點狀語Thereason

如何選擇關(guān)系代詞VS關(guān)系副詞?

①從句缺少主、賓、定關(guān)系代詞關(guān)系副詞②從句缺狀語關(guān)系副詞先行詞在從句中作成分相當(dāng)于wherewhenwhy地點名詞地點狀語時間名詞時間狀語reason原因狀語in,at等介詞+whichat,in,on,during等介詞+whichfor+whichReadthesentencesbelowandcomparethem.Whichchoice(aorb)doyouthinkisbetter?Why?101.aIsthereashopnearby?Iwanttobuysomesweetsintheshop.bIsthereashopnearbywhereIcanbuysomesweets?2.aWecangothereonSunday.FewpeoplegotoworkonSunday.bWecangothereonSundaywhenfewpeoplegotowork.3.aHewassoupsetforsomereason.Hedidn'ttellmethereason.bHedidn'ttellmethereasonwhyhewassoupset.Usingrelativeclauseshelpstomakethesentenceslogicallyclearerandconcise.Relativeclausescanalsohelptoomitrepeatedwordsandexpressions.11Completethesentencesaboutyourselfusingrelativeclauses.1.I'llneverforgettheday____________________________________2.Iwasbornin
