The articles in English are the following:

* a (used in front of a word that begins with a consonant)
* an (used in front of a word that begins with a vowel)
* the

Here are some good exercises to learn how to use these: http://english-zone.com/index.php?ID=21

~~~~~~~~~~~~~~~~~~~~~

Simple sentences have one independent clause. "Jack hit a homerun."

Compound sentences have two independent clauses and are usually joined by a coordinating conjunction (FANBOYS). "Jack hit a homerun, and he was the game's hero."

Complex sentences have one independent and at least one dependent clause in them. "When he least expected it, Jack hit a homerun."

An article is a word that combines with a noun to indicate the type of reference being made by the noun. The three most common are, in no specific order: the, an & a.

When you say 3 simple,compound and complex sentences, do you mean 1 or 3 of each?
P.S. I like to say:
The DEFINITE article is the. The book. The chair. The girls.

The INDEFINITE article is a, an. a book, a chair, an apple, etc.
