Adverb clauses are used to show relationships between ideas. They show relationships of time, cause and effect, contrast and condition.
ex, 1, When the phone rang, the baby woke up. (adverb clause main clause)
2, The baby woke up when phone rang. （main clause adverb clause）
When an adverb clause precedes a main clauses, as in (1), a comma is used to separate the clauses.
when an adverb clause follows, as in (2), usually no comma is used.
3, Because he was sleepy, he went to bed.
4, He went to bed because he was sleepy.
In (3) and (4), because introduces an adverb clause that shows a cause-and-effect relationship.
