Question

定语从句关系代词什么情况下可以省略

Answer 1

关系代词，在限制性定语从句中做从句中的宾语成分的时候是可以省略的。在非限制性定语从句绝对不能省略。
例如：The
girl
（who
is
）standing
there
is
my
sister。括号里的可以省略，standing
there
就做一个后置定语。
但也有几种特殊情况，关系代词不用作宾语也可以省略，同学们学习和使用时请注意。
　　在下列情况下,引导宾语从句的关联词可以省略。
　　一、that在定语从句中作表语时。例如:
　　She
is
all
(that)
a
teacher
should
be.
她具备一个老师应该具备的所有条件。
　　二、that在从句中作补语时。例如:
　　I'm
not
the
fool(that)
you
thought
me.
我不是你以前所认为的那个傻子了。
　　He
is
the
nicest
teacher
(that)
the
students
consider
him
in
their
school.
他就是学生认为学校中最好的那个老师。
　　三、作状语时的省略。
　　1.
当先行词是reason,且在定语从句中作原因状语时,可以用关系副词why或关系代词that,也可以省略。例如:
　　The
reason
(why/that)
he
failed
was
his
laziness.
他失败的原因是因为他懒惰。
　　That
is
the
reason
I
did
it.
那就是我做那件事的原因。
　　2.
当先行词是way,且在定语从句中作方式状语时,关联词可用in
which或that,也可以省略。例如:
　　The
way(in
which/
that)
these
comrades
look
at
problems
is
wrong.这些同志看待问题的方式是错误的。
　　That
was
the
way(in
which
/
that)
she
worked
the
problem
out.
她就是用那种办法解决问题的。
　　3.
当先行词是time时,关联词可用when,
that或省略。例如:
　　The
second
time
(that)
I
saw
him
was
in
2000.
我第二次见到他是在2000年。
　　I
don't
know
the
exact
time
(when/
that)
the
sports
meeting
will
take
place.
我不知道运动会举办的确切时间。
　　4.当先行词是place时,关联词可用where,that或省略。例如:
　　The
place(where/
that)
we
will
have
our
picnic
is
not
decided
yet.
我们举行野餐的地点还没定下来。
　　This
is
the
right
place
he
was
born.这儿就是他的出生地。(注意:句末不可用介词in)
　　同学们往往认为关系代词作宾语时就一定可以省略,其实不然.在下列四种情况下,关系代词虽作宾语,却不能省略。
　　一、在介词+whom
/which结构中,
whom,
which不能省略。例如:
　　Do
you
know
any
shops
nearby
in
which
I
can
buy
flowers?你知道附近有可以买到花的商店吗?
　　That
is
the
headmaster
with
whom
my
father
was
talking
just
now.刚才和我爸爸交谈的那个人是校长。
　　二、在非限制性定语从句中,作宾语的关系代词也不能省略。例如:
　　Mr
Green,
whom
you
know,
is
the
tallest
in
our
school.
格林先生是我们学校里最高的,你也认识他。
　　The
elephant
is
like
a
spear,
as
anyone
can
see.
大象像长矛,任何人都知道。
　　三、在the
same
...
as,
such
...
as,
as
...
as,
the
same...
that结构中,
as,
that
即使作宾语,也不能省略。例如:
　　I
have
bought
the
same
bike
as
you
(have).
(指同类用as)我买了一辆和你的一样的自行车。
　　This
is
the
same
book
that
I
read
the
day
before
yesterday.
这就是我前天读过的那本书。(关系代词that如要换成as,
则指与我读的书一样,而不是同一本。)
　　四、当and,
but,
or等连词连接两个或两个以上的定语从句修饰一个先行词时,关系代词第一个可省略,第二、第三个等不可省略。例如:
　　This
is
the
book
(which)
I
read
yesterday
and
which
I
found
very
interesting.
这就是我昨天读的那本书,它很有趣。
　　You
have
many
people
around
you
(whom)
you
always
turn
to
and
whom
you
will
never
forget.你身边有很多人,你经常向他们求助,你永远不要忘记他们。
