Every Saturday I’ll give you a couple of idioms to learn. An idiom is a saying or phrase whose meaning cannot be taken from the literal meanings of the words.
eager beaver: someone who is a diligent worker, or looks forward to working on a project or similar task.
Example:
He is such an eager beaver when it comes to yard work – he takes pride in his backyard garden.
eat like a horse: eat a lot, have a good appetite
Example:
Are you sure you have enough food for the party? Several kids on Tom’s football team are coming, and they all eat like a horse.
