Sentence Diagramming?

Question

I had a worksheet from school, and in it I am sappose to find a mistake in a diagram and then create a new diagram with the old one corrected. For example, the sentence is : The fire cast strange shadows across the room. In the diagram, "the" belongs to fire, " across the room" belongs to cast, and "strange " belongs to shadows. I think there's something wrong with "accross the room"..... what do you think? HELP ME OUT HERE!

Answer 1

"across the room"... is an adverb phrase.... specifically, it is an adverb of place because it tells where the action occurred. All adverb phrases belong under the verb in a diagram. You are correct... " across the room" belongs under " cast".
