在定语从句中，先行词有the only 修饰时，关系代词只能用that吗？ 比如？

当only修饰定语从句的先行词时，在定语从句中用的关系代词只能是that，不能用which，如：
he
is
the
only
person
that
was
present
at
the
time.
this
is
the
only
bow
tie
that
there
is
in
the
store.
this
is
the
only
sample
that
we
have
received.

yes.
在定语从句中当先行词被the
only、the
very、the
same、the
last四个中的任何一个修饰时只能用关系代词that
EG.
He
is
the
only
person
that
I
want
to
talk
to.
This
is
the
very
book
that
I
want
to
buy.
