General Writing: Unreal Conditions

2 3 4

Adverbial clauses are dependent clauses beginning with subordinating conjunctions. They are attached to independent clauses forming complex sentences.
Examples:

While you were out running around town, I was home taking care of your chores.
I was home taking care of your chores while you were out running around town.

The use of an adverbial clause alone results in a sentence fragment. When it is used to begin a sentence, a comma is usually placed after the clause.

The meanings and functions of adverbial clauses are determined by the subordinating conjunctions used, which are generally classified into:
Time and place: before, after, when, whenever, as, while, until, where, wherever
Cause and effect: because, since, as
Manner and condition: if, as, in case, although, unless

1. Complete each of the following sentences with one of the following subordinating conjunctions: when, whenever, before, after, as, while, until, where, wherever.
Example: When you put on your tie, button the top button of your shirt.

1. the sun began to set, I took out my camera.
2. your alarm goes off, please get up and feed the dog.
3. a hard day at the sawmill, Sam's arms are very tired.
4. I won't answer any of your questions you've given them more thought.
