Question

as there were strange marks on the X-ray plates taken of the mummy
because of the hard resin which covered the skin
两个句子都是定语从句,为什么一定可以不用引导词,另一个一定要用呢
as there were strange marks on the X-ray plates taken of the mummy可不可以改成as there were strange marks on the taken X-ray plates of the mummy,taken既然做定于为什么不放在前面，要放在后面，有什么原因吗？放在前面就不行吗？我可以把taken理解成非谓语动词吗？

Answer 1

the x-ray plates of the mummy 木乃伊的X光片
由于taken要修饰plates,所以就插到of前面去了.
