I had so much for which to be grateful这时定语从句吗

这句话是定语从句的话，从句的主语谓语分别是什么呢，如果写成 I had so much to be grateful for 可以吗，如果可以，和原文有什么区别

I had so much that I am to be grateful for. 定语从句，非正式语体。省略关系代词that，I，am, 得到：

I had so much to be grateful for.不定式作定语。非正式语体。

I had so much for which I am to be grateful. 定语从句，正式语体。省略I，am, 得到：

I had so much for which to be grateful. 正式语体

介词+which+to do 叫做带关系代词的不定式。这种不定式实际是定语从句的一种简略形式，只能做定语。也只用于正式书面语体。
