原文：I found him in a field eating a stale pancake.请问这句话是不是时间状语从句？省略了从属连词？
When I found him in a field,he was eating a stale pancake.
I found him in a field,while he was eating a stale pancake.
可以这样改写吗？
还是I found him in a field.He was eating a stale pancake.这句话和原文相比，原文是由这两句话合并了？

原句是现在分词做定语
后面两句都可以，但是改成了时间状语
最后两句没问题。

应试教育，必须配合出题人心意。
实用角度看，关键是说话人意图是什么

不是。不是

语法太难了是在学什么要学那么多语法
