从句,连接词
all that they have done is good for us.
这句话为什么用that,为什么不能用what.
they have invited us to their party,which is very kind of them.
这句话为什么用which,为什么不能用that.

第一句里用that是因为all的存在,这是一种特殊情况,当定语从句修饰的是all时,选择that来当连接词；
第二句,不能用that首先是因为这里的连接词是放在逗号后面的,不符合语法规范,非限制性定语从句不能用that引导,其次,这里的which指代的是前面整句话,即“他们邀请我们来参加宴会”,that没有指代整句话的功能.
