这句话中的定语从句应该如何理解,我没有找到先行词.
Perhaps for us today,two of the most signifciant aspects of most of these studies of genius are the frequency with which early encouragement and teaching by parents and tutors had beneficial effects on the intellectual,artistic or muscial development of the children but caused great difficulties of adjustment later in their lives,and the frequency with which abilties went unrecongnised by teachers and schools.

Answer 1

很容易找的,楼主!
结构分析：
主语：two of the most signifciant aspects of most of these studies of genius
谓语：are
表语：the frequency+其后引导的定语从句（一共是两个）
骨干：方面是频率
定语从句分析：
先行词：frequency 频率 ————>在定语从句中：early encouragement and teaching by parents and tutors had beneficial effects on the intellectual, artistic or muscial development of the children but caused great difficulties of adjustment later in their lives++ with the frequency++
父母导师的鼓励和教导队孩子智力,艺术,音乐方面有提高且在其之后人生当中有重大影响,伴随着这样的频率,在定语从句中与with充当状语成分
后面一个句子跟这个相同的!
不懂再问,
