Modifying Nouns with Prepositional Phrases
Prepositional phrases, groups of words beginning with prepositions like in, on, near, of) with, about, at, to, for, and from, can also modify nouns. Prepositional phrases have many purposes.
They often tell place:
We bought a house in the country.
The keys on the desk are mine.
She owns the cafe near the railroad station.
But they often give other information as well:
Everyone knows the dangers of smoking.
I bought a car with a sunroof.
She wrote a novel about evil politicians.
In this unit, you will use prepositional phrases to modify nouns. Like other modifiers of more than one word that you studied in Unit Eight, prepositional phrases come after the nouns they modify:
EXAMPLE: The dance club admits everyone.
The dance club is for teenagers.
Everyone is between 18 and 21.
SOLUTION: The dance club for teenagers admits everyone between 18 and 21.
Just as you did in the exercises in the previous unit on adjective modifiers, try crossing out repeated words and forms of the verb be in the sentences containing the prepositional phrases; then place the prepositional phrases after the nouns they modify in the base sentence.
