句子结构分析，结构分析

When students graduate from college,many of them do not know how they want to spend their working lives and they sometimes move from job to job, until they find something that suits them and of equal importance to which they are suited.
and of equal importance to which they are suited.，这里的and 并列的是什么？还有后面是做的是句子的什么分成呢？

Answer 1

When students graduate from college是第一句的状语从句，第一个and后面并列的是they sometimes move from job to job, until they find something that suits them and of equal importance to which they are suited.第二个and是定语从句something that suits them and of equal importance to which they are suited.的一部分直到他们发现某些东西，这些东西是适合他们的，并且最他们合适的东西是重要的，比较复杂的句子可以从主句翻译起，然后把从句补上去，这样好懂

Answer 2

until they find something （that suits them） and （of equal importance to which they are suited.）
括号里的是两个定语从句，先行词都是something
翻译：知道他们找到适合他们的职位，同样的在这样的职位中也能体现出他们的重要性。
这里的until引导的是时间状语从句

追问

后面那个定语从句的引导词是那个呢？which吗 ？something 不是只能用that 吗 ？

追答

有两种情况关系代词用which不用that
1. 关系代词前面有介词
2，如果一句话有两个定语从句，其中的一句关系代词用that了，另一个就用
which
