關(guān)系詞判斷步驟:

首先，要看先行詞。如果先行詞是指人,關(guān)系代詞可用

who,that,whom,whose。如果先行詞指物,關(guān)系代詞可用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

主語

賓語

所有格

人who,thatwho(m),that，xwhose

物which,thatwhich,thatwhose

注意：定語從句謂語動詞和先行詞一致.

注:定語從句的時態(tài)不受主句的限制。Thewoman

who/that

is

my

mother.(主句)Thewomanismymother.(敘述客觀事實(shí)用一般現(xiàn)在時)(從句)Thewoman(who/that)spokeatthemeetingyesterday.(句中yesterday表示過去時間)先行詞前有theonly，thevery，thesame，thelast等詞修飾時，只能用that。例如：ThisisthesamebikethatIlost.以who或which引導(dǎo)的特殊疑問句，為避免重復(fù)，只能用that。例如：Whoisthegirlthatiscrying？

定語從句中其他需注意事項先行詞是物，關(guān)系詞只能用that,而不宜用which的情況1.從句所修飾的詞又被形容詞最高級或序數(shù)詞修飾時

Thisisthemostinterestingstory(that)Ihaveeverheard.Thefirstmeeting(that)wewilltakepartinwillbeheldintheafternoon.

3.先行詞既有人也有物時,只能用thatIcanrememberwellthepersonsandsomepictures(that)Isee.4.先行詞是oneof,theone,或用little,much,few,no,all,some,any,theonly,thevery,thesame,thelast作修飾時

Isittheonethatyouwant?

Ihaven’tgotmuchthatIcanofferyou.

5.當(dāng)主句已有疑問詞who或which時，用thatWhoisthewomanthatwaspraisedatthemeeting?acouchpotatolovestoplayorwatchabookwormlikesreadingverymuchasportsfan
