帶介詞的定語從句是定語從句學習的重要內(nèi)容，也是高考重要考點，學習時要注意下列幾點：
一、明確介詞位置，把握介詞使用要求
關系代詞whom或which在定語從句中作介詞賓語時，介詞可放在后面，也可提前構成“介詞＋關系代詞whom(先行詞指人)/which(先行詞指物)”引導定語從句。
This is the girl whom I borrowed a book from.
=This is the girl from whom I borrowed a book.這就是我向她借書的那個女孩。
Is this the room which he once lived in?
=Is this the room in which he once lived?這是他曾經(jīng)住過的房子嗎?
但下列情況下介詞不能提前。
(1)用who代替whom，that代替which時介詞不能提前。
He's the boy who I learned English from.這是我向他學英語的男孩。
This is the room that he once lived in.這是他曾住過的房間。
(2)當whom,which省去時介詞不能提前。
Is he the boy you went there with?他是你和他一起去那兒的男孩嗎?
This is the room he lived in.這是他住過的房間。
(3)當從句中的謂語是一個動詞短語時，動詞短語中的介詞不能拆開提前。
You're the very man whom I'm looking for.你正是我在找的那個人。
This is the program which he listened to.這就是他聽過的節(jié)目。
二、了解關系代詞省略的背景要求
關系代詞whom或which在定語從句中作介詞賓語且介詞又放在后面時可以省去。
Can you find a girl(whom)I can go to Beijing with?你能替我找一個我可以和她一道去北京的女孩嗎?
Is this the pen(which)you referred to yesterday?這是你昨天提到的那支筆嗎?
但如果介詞被提前，關系代詞whom或which不能省略。
This is the boy on whom you can depend.這就是你可以依賴的那個男孩。(whom不可省)
My glasses without which I was almost like a blind man fell to the ground and broke into pieces.我的眼鏡掉到地上摔成碎片，沒有它我簡直像個瞎子。(which不可省)
三、熟悉關系代詞替換的背景要求
關系代詞whom或which作介詞賓語時，如果介詞放在后面，可用who/that代替whom，that代替which。
Qiu Yike,a new ping?pong star at the 47th World Championships in Paris is the boy(who/whom/that)I'm proud of.邱貽可，47屆巴黎世界乒乓球錦標賽上升起的明星，是我感到驕傲的對象。
This is the laboratory(that/which)he studies Sars in.這就是他研究Sars病毒的實驗室。
但如果介詞被提前，不可用who/that代替whom,也不可用that代替which。
This is the doctor with whom Xiao Wang fought Sars with.這就是小王和他一起與Sars病毒戰(zhàn)斗的醫(yī)生。(whom不能被who或that所替換)
This is the table on which lies a thick dictionary.這就是上面放著一本厚字典的桌子。(which不能被that所替換)
四、掌握帶介詞定語從句的幾種創(chuàng)新形式
(一)介詞＋whose引導定語從句
whose引導定語從句時，可出現(xiàn)創(chuàng)新句型：介詞＋whose引導定語從句。解這種定語從句時需弄清從句的動詞與先行詞、whose后邊的名詞及定語從句主語之間的關系，并發(fā)揮合理想象，不難發(fā)現(xiàn)其中正確的邏輯關系。
She is the girl to whose brother I talked yesterday.她就是昨天我和其兄弟談話的女孩。
析：分析the girl、brother和I之間的邏輯關系，不難發(fā)現(xiàn)我和女孩的兄弟談話。
He is the boy for whose boss I work.他就是我為其老板打工的男孩。
析：分析the boy、boss和I之間的邏輯關系，不難發(fā)現(xiàn)我為男孩的老板打工。
(二)復雜介詞＋whom/which引導定語從句
This is the hotel at the back of which is a small garden.這就是后面有一座花園的旅館。
They came to a farm house in front of which sat a small boy.他們來到一家農(nóng)房，前面坐著一個小男孩。
(三)數(shù)詞(不定量數(shù)詞)／含所屬關系名詞＋of whom/which引導定語從句
She has many books only one of which is interesting.她有許多書，只有一本是有趣的。
I have many friends,the tallest of whom is Wei Fang.我有許多朋友，個子最高的是魏芳。
