除關(guān)系代詞外，還有關(guān)系副詞， when， where， why， 其中 when用來(lái)指時(shí)間，在定語(yǔ)從句中作時(shí)間狀語(yǔ)。如： I never forget the day when I first came to the Great Wall�� 而 where 則指地點(diǎn)，如： This is the house where the old man lives�� 請(qǐng)看下面例句：

　　1.　 The city was beautiful�� We spent our vacation there�豹�

　　2.　 That is the restaurant�� I will meet you there�豹�

　　在定語(yǔ)從句中又可分為兩大類(lèi)定語(yǔ)從句，即限制性定語(yǔ)從句和非限制性定語(yǔ)從句。��

　　①　限制性定語(yǔ)從句是先行詞在意義上不可缺少的定語(yǔ)，如果去掉的話，主句的意思就不完整，意義就表述不明。這種句型一般定語(yǔ)從句緊接先行詞，如：��I was the only person in my office who was invited�豹�

　　②　非限制性定語(yǔ)從句。它與主句的關(guān)系不十分密切，只是對(duì)其附加說(shuō)明，也就是講即便去掉定語(yǔ)從句，句意也不受影響，仍然清晰明了。這樣的定語(yǔ)從句要在它和主句之間加一逗號(hào)分開(kāi)。且關(guān)系代詞不引導(dǎo)這種非限制性定語(yǔ)從句，如： Abraham Lincoln， who led the United States through these years， was shot on April 14，　1865 at a theatre in washington�� D.　C.　又如：Galileo lived in the city of Pisa， where there is a leaning tower about 180 feet high�豹オ�
