关于that和which的一个语法问题,
这是新概念英语第三册中的一句
but the inspector found a dirty red bundle that contained jewellery which the old lady said was not hers
请问这句中的that which 可以互换吗,或者都能用that 或 which吗

可以.
多数时候that和which都可以互换,除了：1、that可修饰人/物,which只能修饰物；2、非限定性定语从句只能用which（A,which+句子）；3、前面有介词时只能用which（如：of which...）

可选

不用that,因为前文出现过that

不能同时用which或that，英语中是避免重复，不是语法不对。
