求英语定语从句最难的一种形式，英语高手帮忙

就是最难理解的一种形式，一道题目或者一种句型结构都可以。

Mary was disappointed to see the washing machine she had had repaired went wrong again.

Clothes which has been worn only a few times has to be put aside because of the changes of fashion.

译文：衣服尽管才穿了没几次，也因款式过时而不得不搁置一边。

考点分析：定语从句的魅力再一次体会了出来！

And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who his not had an active mind.

译文：习惯于多动脑筋而不是少动脑筋的人，在进入老年以后，要比从来不积极动脑子的人的认识能力更健全。

考点分析：本句除了定语从句这一考点外，又重新出现了翻译考项经常考的另一个考点，就是比较级(…more cognitively sound than…)以及连词短语(…rather than…)。考生可以从译文中找到答案。对于考生来讲，应该从平时做阅读时就能够很好地体会这些语法现象。请注意下划线短语的中文翻译方法！
