　　定語從句的引導(dǎo)詞分為關(guān)系代詞（who， whom， whose， which， that）和關(guān)系副詞（where， when， why）兩類，這些引導(dǎo)詞在引導(dǎo)定語從句的同時(shí)均在從句中充當(dāng)成分。關(guān)系代詞可作主語、賓語和定語，作賓語時(shí)可省略；關(guān)系副詞可作狀語，一般不能省略。下面簡單介紹一下定語從句的難點(diǎn)。

　　一、介詞（短語） 關(guān)系代詞 / 副詞

　　1. 此處關(guān)系代詞只能是which / whom / whose / where / when，而不能用who / that.

　　如：They arrived at an old building， in front of which stood a tower. He climbed up to the top of the tree， from where he could see clearly what was happening in the woods.

　　2. 不定代詞 / 數(shù)詞 of which / whom.

　　如：Mrs. Green has three sons， none of whom works in the city. The boys discovered many pictures on the walls of the cave， most of which dated back to 15，000 years ago.比較：The boys discovered many pictures on the walls of the cave， most of them dating back to 15，000 years ago. （此處是獨(dú)立主格結(jié)構(gòu)）
