题目

两个that前的部分理解,后面的第一个that 我理解为引导词,难道第二个是从句中的代词?
the methods that a community devises to perpetuate itself come into being to preserve aspects of the cultural legacy that that community perceives as essential .后面两个that 中的第二 如是代词,应该没有必要加呀?可能我理解 的方向本就不对!
还是说 两个that 中的第二个 只是特指 那个 community!如果是这样，那我把问题弄复杂了哈^^

答案

this is a very cumbersome sentence.Let us take a look of this sentence.
the methods that a community devises to - the first 'that' is a relative pronoun representing 'methods' giving more detail of 'methods'.Therefore you see the following clause of 'devising to perpetuate ..'
Then we see 2 more 'that' later on and stacking with each other.
Let us look at the first that - this function is to link up the sentence before and after itself
the second 'that' - you already know.But without the second 'that' as a relative pronuon for cultural legacy.
you can say that the sentenc is telling us:A community can come into existence by designing methods to presreving its cultural legacy.
