在定语从句中which和that的用法区别

Answer 1

在限制性定语从句里，如果先行词是物，which和that的用法基本上是一样的，作宾语时，都可以省略，作主语则保留。但是，在非限制性定语从句里，只能用
which
不能用that。
只能用that不能用which的情况：先行词前有下列词语修饰时,
定语从句必须用
that
引导。
all,
every,
any,
little,
few,
much,
no,
only,
very,
the
+
序数词,
the
+
形容词最高级
eg.
this
is
the
cleanest
park
that
you
can
imagine.
eg.
this
is
the
only
book
that
has
been
written
in
french.

在
who
或
which
引导的特殊疑问句中，限制性定语从句必须用
that
引导。
eg.
who
is
the
man
that
is
standing
over
there.

先行词在从句中作表语时,
限制性定语从句通常用
that
引导。(常可省略)
eg.

the
girl
that
she
