In Michael Swan' Practical English Usage (OUP, 1996), it says that "the" is not used withe superlative adverbs, when we compare the same person or thing in different situations.
e.g., She works hardest when she's doing something for her family.
It often says "the" is sometimes dropped before superlative adverbs in an informal style.
e.g., Who can run (the) fastest?
But can we drop "the" in the following situations? We are not comparing the same person or thing in different situations, instead, we are comparing a group of people of things.
Trees live the longest of all things on Earth.
He plays the violin the worst of all our students.
Really find it boring to ask questions about these "the"s, but it seems unavoidable when it comes.
Thanks in advance.
