Verb+Preposition

Many verbs are followed by a preposition:
hear of: Have you heard of Spice Girls?
read about: I read about the fight between the two families.
speak to: Camila won't speak to Daniel.

Most verbs can have more than one preposition. Usually this changes the meaning:
apologise for: I apologise for my behaviour last night.
apologise to: I apologised to John for swearing at his sister.
complain about: Leigh complained about the food.
complain to: Leigh complained to the waiter.

Sometimes using a different preposition after a verb doesn't change the meaning:
speak to/with: I need to speak to/with you.
think about/of: I'm thinking of/about you.

Sometimes using the same preposition after a verb can have more than one meaning:
She went through the park. (go through = go cross)
She went through the details (go through = to explain)
