that不能当主语吗

Question

如题所述

Answer 1

你好，同学。
That是一个代词，既可指人，也可指物，当然可以做主语。比如最简单的句子：
This is a book. That is a box.
另外，在定语从句中，that还可以用作关系代词作主语指人或物。比如：
The
book
is
about
a
girl
that
runs
away
from
home.
(这里的that也可以换作who)
What
was
the
name
of
the
horse
that
won
the
race?
(这里的that也可以换作which)
The
police
have
caught the
man
that
stole
my
car.
(这里的that也可以换作who)
