Question

英语问题？

But schools rarely dig down to find out what really makes an applicant succeed, to create a class which also contains diversity of attitude and approach—arguably the only diversity that, in a business context, really matters.
老师说,to creat a class是并列结构，我想知道他为啥是并列结果啊，并列不是一般有连词吗

Answer 1

To create 和 to find out明显是并列的成分。都做 dig down后面的目的状语。是并列的成分。不是并列句。所以不需要连词。

Answer 2

But schools主 rarely dig down谓 to find out （what really makes an applicant succeed宾语从句）目的状语, to create a class （which also contains diversity of attitude and approach定语从句）并列目的状语—arguably the only diversity同位语 that, in a business context, really matters定语从句.
to find out，to create a class都是目的状语，用逗号来并列。

Answer 3

结构2：名词或代词(主格) + doing
1)My mother cooking in the kitchen, I was doing my homework in my room. （表伴随）我妈妈正在厨房做饭，我在房间里做作业。
