Joe asked me to bring his jacket. Being the accounts manager made Milo feel important. Hiking for two hours, Ashley developed blisters on both feet. Everyone wanted the Silver Foxes to win the championship. Fred's favorite activity is blowing bubbles to his little sister. Gerund Phrases

The gerund phrases are:

"Being the accounts manager" (Subject) "blowing bubbles to his little sister" (Subjet Complement)

Gerund phrases begin with a gerund or - ing word, and include other modifiers and objects. They function as nouns, and can be the subject, subject complement or direct object of the sentence.

The rest of the alternatives are not gerund phrases because options one and three possess an infinitive verb ("to bring" and "to win"), and "Hiking for two hours" is a present participle clause.
