We’re looking for someone with experience for this post.
Generally, we know that "look for" means "try to find" and "find" means "successfully get something after searching for it"
My question is that
When to use "find" & when to use "look for"?
could you go find Tommy?
could you go look for Tommy?
I want to find a good stone
I want to look for a good stone (does it sound strange?)
But seem we don't use "find" with continuous tenses
"I am finding my book" sounds strange
But "I am looking for my book" sounds ok.
