定語從句關(guān)系代詞的用法:當(dāng)先行詞是物時,用which

或that引導(dǎo).Thesearethetrees

which/thatwereplantedlastyear.當(dāng)先行詞是人時,用who,whom,whose,that引導(dǎo).who,whom,whose,that用法區(qū)別.who/that作定語從句的主語或賓語.Theman

who/thatisspeakingatthemeetingisaworker.Themanisaworker.Themanisspeakingatthemeeting.分解作主語做題思路：先分解——分析——再合并whom/who/that作定語從句的賓語Thewoman（

whom/whom/that)

theywantedtovisitisateacher.Thewomanisateacher.Theywantedtovisitthewoman.分解作賓語注意:

關(guān)系代詞作動詞賓語時可省略.whose作定語從句的定語.Iknowthegirlwhose

motherisateacher.分解Iknowthegirl.Thegirl’smotherisateacher.作定語Ofwhom

關(guān)系代詞判斷步驟

首先，要辨別出先行詞。如果先行詞是指人,關(guān)系詞可能就用who,thatwhom,whose。如果先行詞指物,關(guān)系詞可能用which或that

然后，要確定關(guān)系詞在從句中的成分。請看下表先行詞

定語從句關(guān)系詞的確定:a.先行詞的分類b.先行詞在從句中充當(dāng)?shù)某煞秩耍簑ho/that物：which/that2.先行詞做賓語人：who/whom/that物：which/that3.先行詞做定語人：whose/ofwhom物：whose/ofwhich4.先行詞做狀語：when/in(on)which,where/in(at)which,why/forwhich1.先行詞做主語定語從句使用中應(yīng)注意:

(1)先行詞為all,everything，anything，nothing,something,nothing,few,little,much,theone等不定代詞時；

(2)先行詞被形容詞最高級所修飾或被theonly,thevery,thelast,any,few,little,no,all,oneof等修飾時：

(3)先行詞為數(shù)詞或被序數(shù)詞（含last)修飾時。（4）先行詞是并列詞組既有人又有物時。

(5)在以who,which開頭的句子中為了避免重復(fù)?？谠E：不定代詞這一伙，全用that準(zhǔn)沒錯先行詞前有修飾，千萬不能用which.A.只能用that,不能用which的情況：

B.只能使用which的情況1.關(guān)系代詞前有介詞時；2.先行詞本身是that時；3.非限定定語從句口訣:要有which別著急，介詞提前逗隔離。e.g:1.Thisistheclassroomin

whichwestudiedfortwoyear.2.Shehastwodolls，whicharefromherparentsC.從句謂語動詞的情況1._____cleanstheblackboardshouldbepraised.

A.That

B.Who

C.Theonewho

D.Thestudentswho注意：①當(dāng)關(guān)系詞作定語從句的主語時，從句謂語動詞的形式應(yīng)與先行詞的人稱和數(shù)保持一致。②若句中無先行詞，先補出先行詞再判斷用法。2.這就是救了那個孩子命的醫(yī)生.Thisisthedoctor

whosavedtheboy’slife注意：定語從句的時態(tài)不受主句影響。1.Thisisthehousein________wehavelivedfor10years.2.I’veneverheardofthepeopleandthings________youtalkedaboutjustnow.whichthat當(dāng)先行詞同時指人和物時，關(guān)系代詞只能用that.Exercise.3.Thisisthefirstplay
