How do you find an adverb clause?

A clause must contain a subject and a verb to be complete. An adverb clause also begins with a subordinating conjunction, such as "after," "if," "because" and "although." If you see a group of words in a sentence that acts like an adverb but does not have both a subject and a verb, it's an adverb phrase.
