这两个句子我看不太懂啊。请教各位

1.  For about 400 years, following the ideas of French philosopher XXX, those who thought about its nature considered the mind related to the body, but separate from it.    [红色部分结构、关系看不懂]

2.  They are put off by the notion that such rich experiences could be reduced to mechanical or chemical bits.   [put off 和bits 有什么特殊意义？]

谢谢了

补充：在这篇文章后面的翻译中 put off 被翻译成了“感到厌恶”
            但我在网上查的put off只有
1. 延期,推迟;拖延
2. 阻碍做某事
3. (停车)让某人下
4. 使分心
5. 关掉
6. 敷衍, 推诿
7. 脱去(衣、帽等)
8. 丢弃, 摆脱

所以说这个put off 到底什么怎么回事？有特殊用法吗？

1.
those (who thought about its nature) considerd  (the mind related to the body , but separate from it)
2.
put off  需要上下文
bit 【informal】a small piece or amount of something

第二句单词或者搭配有问题的建议还是自己多翻一下字典才能够记忆深刻
补充一下put off : to hold back to a later time
这个搭配建议记住，有一年的完型考过

[s:2] 原句 1. For about 400 years, following the ideas of French philosopher XXX, those who thought about its nature considered the mind related to the body, but separate from it.
分析：
who thought about its nature 修饰前面的those，为后置定语；
considered 是谓语动词；the mind 是宾语；
related to the body,是后置定语，修饰前面的 the mind ；
but 是连词，连接两个相同的成分，在这个句子中，本人认为separate应该用过去式，separated，与前面的动词considered 并列；本人认为这是理解句子的关键。
it 是代词，指代前面的the mind，避免重复。
红色部分应该这样划分成分：
those〈 who thought about its nature〉 considered the mind 〈related to the body〉, but separated from it.
大体翻译一下就是：四百年来，沿着法国哲学家某某某的思想道路，这些考虑了它的本质的人们，参考了与这个问题相关的思想，但是却都背离了原来的研究道路
[s:9] 个人意见，仅供参考，呵呵

红色部分主干：those considered
those是指一群人，后面who引导的从句就是修饰those的，指明是什么样的人
considered 后面的都是considered 的宾语
其中有省略的部分：
the mind related to the body, but separated from it.————>the mind related to the body, but the mind separated from it （the body）。

建议查英英词典，而不是英汉
put somebody off：（British English）to make you dislike something or not want to do something
