Question

Identify the prepositional phrases, the subject and the verb in this sentence."After turning onto Main Street, drive for one mile."

Answer 1

Hi I hope this helps. Your answer should be Main Street

Answer 2

Drive is the verb, the prepositional phrase is after turning onto Main Street.
Put you for the subject, because the person is talking to another, and although the subject is not named, the proper way is to put you - subject, drive - verb, after turning onto Main Street - prepositional phrase.
