问题描述
In time, it became an accepted fact that the Cox brothers employed a conscientious ghost that did most of their work for them.
这里 that did most of their work for them.
这里主语省略了吗，可以改成 that it did most of their work for them.
或者省略掉 that，直接说成 the Cox brothers employed a conscientious ghost (did most of their work for them)吗？
老师答疑
曹老师：
the Cox brothers employed a conscientious ghost that did most of their work for them.
that did most of their work for them是定语从句。修饰ghost。that在意义上指代ghost，并在从句作主语。
关系代词在定语从句中作主语，只有一下几种情况在非正式语体可以省略关系代词。
1 从句修饰there be句型中的真正主语时：
There is a man (who/that) asks for you.
2 关系代词为there be句型中的真正主语：
I had to use anything (that) there was.
3 This is the man (who) wants to see you.
4 It is the man (who) wants to see you.
其余情况都不可省略在定语从句中作主语的关系代词。
提问者的问题可能是没有看出定语从句导致的。
句子分析：
In time, it became an accepted fact that the Cox brothers employed a conscientious ghost that did most of their work for them.
in time: 时间状语
it：形式主语
became：系动词
an accepted fact: 表语
that the Cox brothers employed a conscientious ghost that did most of their work for them：真正主语从句
主语从句进一步分析：
that：引导主语从句的从属连词
the Cox brothers: 主语
employed: 谓语
a conscientious ghost: 宾语
that did most of their work for them：定语从句修饰ghost. 其中that为主语，did为谓语，most of their work为宾语，for them为状语。
陈老师：
In time, it became an accepted fact that the Cox brothers employed a conscientious ghost that did most of their work for them.
这里 that did most of their work for them.
这里主语省略了吗，可以改成 that it did most of their work for them.
或者省略掉 that，直接说成 the Cox brothers employed a conscientious ghost (did most of their work for them)吗？
解答如下：
that did most of their work for them 为一个由“关系代词that" 引导的定语从句，修饰/限定前面先行词为”a conscientious ghost", 关系代词that在定语从句充当主语成分，不可以省略。
(特别备注：引导定语从句关系代词，只有在定语从句充当宾语成分时，方可以省略，作主语是不可以省略。）
或者省略掉 that，直接说成
the Cox brothers employed a conscientious ghost (did most of their work for them)吗？
以上句子在没有任何连词的情况下出现2个谓语动词，是一个错误的句子
