Explanation

An adverb phrase:

• is a reduced adverb clause. Adverb clauses can be reduced in ONLY one situation. Reduce an adverb clause only when the subject of the adverb clause is the same as the subject of the independent clause.
• has the same meaning as the adverb clause.
• has no subject.
• does not have a complete verb.
• follows two general rules:
  - When the adverb clause has a "be" verb form, omit the subject and the "be" verb form.
  - When the adverb clause does not have a "be" verb form, omit the subject and change the verb to its participle (-ing) form.
