什么时候只能用that，什么时候只能用which？

Question

如题所述

Answer 1

定语从句
以下情况用which不用that.
(1)
当关系词前面有介词时，指物常用which.
the
prize
for
which
he
worked
so
hard
was
a
new
bike.
he
built
a
telescope
through
which
he
could
study
the
skies.
(2)
非限制性定语从句指物时，多用which.
bamboo
is
hollow,
which
makes
it
light.
he
wrote
an
article,
which
tells
us
about
the
computer.
(3)
如果先行词本身是that时，只用which.
this
is
that
which
he
bought
yesterday.
(4)
which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分概念。在这种从句中，which可以作主语，也可以作宾语或表语，多数情况下意思是与and
this
相似，例如：
he
succeeded
in
the
competition,
which
made
his
parents
very
happy.

Answer 2

在定语从句中只能用that引导，而不能用which引导的情况：
1、
如果先行词是all,
much,
anything,
something,
nothing,
everything,
little,
none等不定代词，关系代词一般只用that，不用which。例如：
all
the
people
that
are
present
burst
into
tears.
is
there
anything
that
i
can
do
for
you?
2、如果先行词被the
only,
the
very,
the
same,
the
last,
the
best等词修饰，关系代词常用that(指人时，可以用who)，例如：
this
is
the
very
book
that
i
want
to
find.
that
is
the
best
film
that
we
have
seen.
i
was
the
only
person
in
my
office
that/who
was
invited.
3、当先行词被all,
every,
no,
some,
any,
little,
much所修饰时；
you
can
take
any
seat
that
is
free.
4、当先行词被序数词或形容词最高级所修饰时。
it
is
the
first
foreign
book
that
i
have
ever
seen.
this
is
the
most
beautiful
flower
that
i
have
seen.
5、
在there
be句型中，常用that.
there
is
a
man
that
lives
in
that
village.
6、先行词有两个，一个指人，一个指物，关系代词应该用that。例如：
the
boy
and
the
dog
that
are
in
the
picture
are
very
lovely.
以下情况多用which：
1、当关系词前面有介词时，指物常用which.
the
prize
for
which
he
worked
so
hard
was
a
new
bike.
he
built
a
telescope
through
which
he
could
study
the
skies.
2、非限制性定语从句指物时，多用which.
bamboo
is
hollow,
which
makes
it
light.
he
wrote
an
article,
which
tells
us
about
the
computer.
3、如果先行词本身是that时，只用which.
this
is
that
which
he
bought
yesterday.
4、which还有一种特殊用法，它可以引导从句修饰前面的整个主句，代替主句所表示的整体概念或部分概念。在这种从句中，which可以作主语，也可以作宾语或表语，多数情况下意思是与and
this
相似，例如：
he
succeeded
in
the
competition,
which
made
his
parents
very
happy.
