解析一下这句话,晕了 (结构不懂

nothing （she had studied in her educational curriculum 定语从句修饰nothing）helped（vi.谓语-有用）
没有什么（她在教育课程中学到的）有用.也就是什么都没有用
she certainly hadn't seen anyting like it in her student-teaching days back in Phoenin
（在她在菲尼克斯的学生时代中）她当然没有见过什么东西像这个样过.
in her student-teaching days back in Phoenin是时间副词短语,在她在菲尼克斯的学生时代中
