Question

求分析一个英语复合句

some graduates have come up with the finding that certificates have far less impact on job-hunting than is generally supposed.请问，than is generally supposed 应该是比较状语从句对吧，请问此处有省略吗，请高手指教。

Answer 1

首先some graduates have come up with the finding 是主句，that certificates have far less impact on job-hunting than is generally supposed是修饰finding的同位语从句，而同位语从句中又用了比较级此处可人为有省略，可补充为，that certificates have far less impact on job-hunting than （certificates ） is generally supposed，此处意思为证书在对找工作的影响没有人们想象的那么重要。

Answer 2

我不会讲，但是可以明确地说没有省略，
what
happened是名词性从句，就充当名词。happened是happen的过去式，不是过去分词。
interpretation
of
what
happened对发生了什么的解释。
