4 sources of sentence

Simple:

1. " I was seven years old on a troopship heading to the Philippine Islands. "(pg.1) (http://minh-khieu.blogspot.com/)

I think that this sentence structure is a good example of a simple because in the user explanation stated that this sentence has a subject and a verb. Also, this sentence has a complete independent clause but no dependent clause.

Compound Sentence:

"I had just sat up and it drove me back down." (Pg. 55) (http://don4tell4.blogspot.com/)

I think that in this sentence it has two independent clauses that are joined with a coordinating conjunction of "and".

Complex:

“The Sea was there, deep cobalt, immense, rising like a great saucer to the blue horizon, where it was impossible to see a defining line between water and sky.”(p.1) (http://alexjudeng.blogspot.com/)

I think that this sentence has a complete independent clause with a join of a dependent clause. The dependent clause starts with a "where" and ended as "sky". This dependent clause is an adjective clause which is described the noun "horizon".

Compound complex:

Then I began to read about the sea and found that the Pacific Ocean was so enormous it dominated the entire planet; all the land mass in the world could fit inside the Pacific and there would still be sea around it. P. 10 (http://englishwitheuphrasie.blogspot.com/)

I think that this sentence has two independent clause that joined with a coodinator of "and"; it has a dependent clause that started with "then" and ended with "planet".
