An adverb clause will meet three requirements:
•First, it will contain a subject and verb.
•You will also find a subordinate conjunction that keeps the clause from expressing a complete thought.
•Finally, you will notice that the clause answers one of these four adverb questions: How? When? Where? or Why?
