  2. ※Definitions and Purposes: • A dependent clause introduced by an adverbial subordinator. • Used to modify the verb of the independent clause and to indicate time, place, reason, and so forth. It is also used to show contrast.

  4. ※ Simple punctuation: • adverbial clauses are placed before and after an independent clause. • Ex. Because scientists are interested in the planets, they send spacecraft to orbit them. • Scientists send spacecraft to orbit the planets so that humans can learn more about the universe.

  5. ※Types of Adverbial Clauses:
