高考語法專題：定語從句
考綱新研讀
考查的重點是介詞+關系代詞which，whom引導的定語從句；非限制性定語從句也時有考查。
1.限制性定語從句
句子作定語，由關系代詞和關系副詞引導，被修飾部
分叫先行詞。
(1)關系代詞：that, which, who, whom, whose,在句子中
作主語或賓語，作賓語時可省略。
that,指人或物：
who is the man that is reading the newspaper over there?
the finger (that) i put into my mouth was not the one
(that) i
had dipped into the cup.
which,指物：
a chemical’s shop is a shop which sells medicine.(作主語)
the film (which) we saw last night was wonderful.(作賓語)
who, whom, whose,指人，分別做主語、賓語和定語：
the man who visited our class yesterday is our new headmaster.
who’s the man (whom) you just talked to?
this is the room whose window faces south.
介詞后指人用whom,指物用which。
介詞可提前，也可在后；在后時可用who, that，也可省略：
this is the room in which we lived last year.
= this is the room
(which/that) we lived in last year.
who’s the man with whom you just shook hands?= who’s the
man (who/whom/that) you just shook hands with?
但是固定搭配,介詞不能提前：
is this the book which she was looking for?
(2)關系副詞：when, where, why,在定語從句中分別作時間、地點
和原因狀語。
when,指時間：
i still remember the day when (on which) i first came to beijing.
比較：i still remember the day that i spent in beijing.
where,指地點：
this is the house where (in which) i lived two years ago.
比較：this is the house that i bought two years ago.
why,指原因：在“reason”后：
the reason why he was late is that the car broke down on the way.
比較：the reason that he gave us is not reasonable.
