Locative phrases (phrases denoting locations, such as at the schoolor on the table) may come before or after the verb. Preverbal locative phrases normally refer to where an action took place (e.g. I read the book at the library), whereas postverbal locative phrases generally denote the place where something or someone ends up being as the result of an action (e.g. I put the book on the bookshelf).
