Question

分析这句话的语法成分

It’s not as hard for them to transform their thought processes as it is for older students.

Answer 1

It形式主语's系动词 not as hard表语 （for them to transform their thought processes as it is for older students动词不定式复合结构真正主语）.
for them宾 to transform their thought processes宾补 （as it is插入语） （for older students状语）
对他们来说，改变他们的思维过程并不像对年长的学生那样困难。

Answer 2

第一个as相当于so，作副词修饰hard，意为“如此；那样”；

It's not as/so hard 主系表，it是形式主语；
for them 对象状语，翻译的时候可以先译；
to transform their thought processes 句子真正的主语；
as it is for older students as从句作方式状语，as it is已经是个习语，意为“像...那样；按照...的样子”。
所以这个句子可以翻译成“对他们来说，改变他们的思维过程，不像对年长的学生那样困难。”
