Mrs Brown was much disappointed to see the washing machine she had had repaired went wrong again?

问题描述:

Mrs Brown was much disappointed to see the washing machine she had had repaired went wrong again?
为什么填 repaired?it repaired行吗?

不行,此处是定语从句,先行词是machine,引导词that被省略
第一个had是过去完成时的助动词,第二个had实际上正是词组have sth done的成分,但是定语从句中不需再加it或者machine
