Unit4NaturalDisasters定語從句——關(guān)系代詞引導(dǎo)的定語從句

一、

什么是定語？

二、什么是定語從句？定語是用來描述名詞或代詞的修飾語，它常和名詞構(gòu)成名詞短語。定語分前置定語和后置定語兩種。定義：在復(fù)合句中起定語作用的句子稱為定語從句，定語從句可以用來修飾名詞、代詞或整個句子。被定語從句修飾的部分為先行詞，引導(dǎo)定語從句的詞為關(guān)系詞。翻譯為“……的”。分類：限制性定語從句：無逗號，從句是主句不可缺少的部分。非限制性定語從句：有逗號，主句完整，從句是補(bǔ)充說明。關(guān)系代詞不可省略，不能用that。關(guān)系詞關(guān)系代詞關(guān)系副詞作用：引導(dǎo)定語從句——連接先行詞和定語從句；代替先行詞；在定語從句中充當(dāng)成分。that\which\who\whom\whose\as在從句中，作主語、賓語、表語或定語where\when\why在從句中作（時間、地點(diǎn)、原因）狀語一、識別從句：主句＋關(guān)系詞＋從句二、劃分從句：先行詞＋（關(guān)系詞+V1（從句謂語）...）＋V2（主句謂語）1.找到關(guān)系詞（從句的開端）2.找到連接詞后2個謂語動詞3.畫左括號（從連接詞開始）4.畫右括號（到從句結(jié)束）eg.HeisMike(wholikestoys).\Theboy(wholikesthetoys)isMike.識別定義從句＋做題1.判從句：名詞或代詞后的句子一般為定語從句；劃分出定語從句：先行詞＋（關(guān)系詞+V1（從句謂語）...）＋V2（主句謂語）2.析成分：分析從句所缺成分。3.看先行詞：看先行詞指人指物還是整個主句。①(教材典句)Thereweredeepcracksthatappearedinthewellwalls.②(教材典句)Thesupplieswhichwereprovidedtothedisasterareawerecollectedfromaroundthecountry.③(教材典句)Thenextday,peopleputupsheltersintheopenairusinganythingthattheycouldfind.④(教材典句)Thenumberofpeoplewhowerekilledorbadlyinjuredinthequakewasmorethan400,000.⑤(教材典句)Soonafterthequakes,thearmysent150,000soldierstoTangshantodigoutthosewhoweretrappedandtoburythedead.⑥(教材典句)Workersbuiltsheltersforsurvivorswhosehomeshadbeendestroyed.⑦(教材典句)Theinjuredboywhosemotherwaslostinthedisasterwastakentothehospital.⑧Socialmedialikeblogshascomebetweenusandthefriendswhomwelove.用法感知關(guān)系代詞的用法關(guān)系代詞先行詞所指在從句中充當(dāng)?shù)某煞质欠窨梢允÷詗ho人主語、賓語賓語可省whom人賓語可省whose人、物定語不可省that人、物主語、賓語、表語賓語可省which物主語、賓語賓語可省as人、物、事主語、賓語、表語賓語可省當(dāng)先行詞前有thesame/such/as/so時，關(guān)系代詞只用as：eg.This
