定语从句分类
定语从句
The
Restrictive
Attributive
Clause限制性定语从句
The
Non-Restrictive
Attributive
Clause非限制性定语从句
限定性定语从句与非限定性定语从句得区别:
限定性定语从句是句中不可缺少的组成部分，主句和从句之间不用逗号隔开。
引导词：关系代词和关系副词，作宾语时一些关系代词可以省略
非限定性定语从句是对主句先行词的补充说明，没
( http: / / www.21cnjy.com )有这种从句不影响主句意思完整.一般用逗号把主句和从句分开。引导词：who,
whom,
whose,
which,
of
which,
when,
where等，不用that,不能省略
Step3.关系词的用法：
(一）关系代词的用法：
1、作主语用who,
which和that,
如：
He
is
the
man
who/that
lives
next
door.
The
train
which/that
has
just
left
is
for
Shenzhen.
2、作宾语用whom,
who,
which,
that,
如：
The
man
(whom/who/that)
we
have
just
seen
is
a
famous
writer.
Where
is
the
book
(which/that)
I
bought
last
week
注：在非正式文体中，关系代
( http: / / www.21cnjy.com )词作宾语时，用于指人的who
whom,
that和用于指物的which和that通常可以省略；但在介词提前时,或在非限定性定语从句中，关系代词即使作宾语也不可省略。
3、作定语用whose,
如：
(a)
He
is
the
man
whose
car
was
stolen
last
week.
(b)
It
was
( http: / / www.21cnjy.com )a
meeting
whose
importance
I
did
not
realize
at
that
time.
注：“whose
+名词中心词”这一结
( http: / / www.21cnjy.com )构在定语从句中既能作主语（如上a句），又能作宾语（如上b句）。whose
的先行词常用来指人，但有时也可以用来指具体事物或抽象概念，这时可以与of
which
结构互换，词序是：“名词+of
which”，如：
They
came
to
a
( http: / / www.21cnjy.com )house
whose
back
wall
had
broken
down.
(=
the
back
wall
of
which)
He’s
written
( http: / / www.21cnjy.com )a
book
the
name
of
which
I’ve
completely
forgotten.
(=
whose
name)
4、作表语只用that
，它既可以指人，也可以指物，但时常省略。
He
is
no
longer
the
man
that
he
used
to
be.
This
is
no
longer
the
dirty
place
(that)
it
used
to
be.
难点:as
引导限定性定语从句，指代被
the
same,
such,
as,
so
等修饰的名词
Don’t
talk
about
such
things
as
you
don’t
understand.
We’re
facing
the
same
problems
as
we
did
years
ago.
It
is
as
pleasant
a
film
as
I
have
ever
seen.
Here
is
so
big
a
stone
as
no
one
can
lift.
比较：
Here
is
so
big
a
stone
that
no
one
can
lift
it.（结果状语从句）
