一个很简单的关于主语从句的问题,我搞了It turned out that what he said was true.可变为What he said turned out to be true.可不可以说成That what he said turned.可不可以有thatthat what 在句中是否可以连用？我们一个老师说可以，一个说不可以
问题描述：
一个很简单的关于主语从句的问题,我搞了
It turned out that what he said was true.可变为What he said turned out to be true.可不可以说成That what he said turned.可不可以有that
that what 在句中是否可以连用？我们一个老师说可以，一个说不可以
答
不可以
加that后前面就变成一个整体了
句意就不对了
答
不可以因为What he said turned out to be true是what引导的主语从句that不能充当主语 It turned out that what he said was true是it that引导的句子
