关于一个句子，谢谢了

found by the Chinese是非谓语短语作定语，如果改成定语从句的话，是：which/that was found by the Chinese。
假如你把它改成was found的话，此句就有两个动词了。

过去分词作后置定语，修饰water，是被中国人发现的。如果用was found，就有两个谓语，应该改为The water which was found by the Chinese has changed

the water found by the Chinese是一个宾语从句,还原语序为the Chinese found the water.如果你一定要用was found，就应该用the water which was found，宾从中which was是可以省略的
