Answer 2

看从句的句子结构是否完整！
如果从句的结构是主+谓+宾，that可省，如缺成分则不可省
有点例子，仔细看看吧！
1、who,
whom,
that
这些词代替的先行词是人的名词或代词，在从句中所起作用如下：
(1)
Is
he
the
man
who/that
wants
to
see
you?
他就是想见你的人吗？（who/that在从句中作主语）
(2)
He
is
the
man
whom/
that
I
saw
yesterday.
他就是我昨天见的那个人。（whom/that在从句中作宾语）
2、Whose
用来指人或物
(只用作定语,
若指物，它还可以同of
which互换，指人的时候也可以用of
whom
代替）
(1)
They
rushed
over
to
help
the
man
whose
car
had
broken
down.
那人车坏了，大家都跑过去帮忙。
(2)
Please
pass
me
the
book
whose
(of
which)
color
is
green.
请递给我那本绿皮的书。
3、
which,
that
它们所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等，例如：
(1)
A
prosperity
which
/
that
had
never
been
seen
before
appears
in
the
countryside.
农村出现了前所未有的繁荣。（which
/
that在句中作主语）
(2)
The
package
(which
/
that)
you
are
carrying

to
come
unwrapped.
你拿的包快散了。(which
/
that在句中作宾语）
