关于learn from receive from的提问

老师，请看两个句子 receive messages from my friends 中这里的介词短语做的是定语么？还有learn the skill from my teacher中，介词短语是做状语么，请老师确认。

I received messages from my friends.

from介词短语可能是状语，也会是定语，取决于语境。比如：

假如这句话是对 What did you receive? 这个问题对回答，则介词短语为定语。

假如这句话是对What did you receive from your friends?这个问题对回答，则介词短语为来源状语。

I learned the skill from my teacher. 介词短语为来源状语。不可能是定语。
