Respuesta :

After I ran three miles, I was tired. 

The first part of the sentence is dependent on the rest because it can no longer stand alone as it's own sentence.

Answer:

The answer to your question would be that the a combination of the sentences above would be as follows: I ran three miles, so I was tired.

Explanation:

The sentence above is a complex sentence: It contains a independent clause and a dependent one. The first one represents a complete thought and can stand alone as a sentence, whereas the second one fails to do so (see A). Subordinating conjunctions link a dependent clause to a independent one. The subordinating conjunction indicates that the dependent clause has informative value to add to the sentence's main idea.

a) *So I was tired

A shows that the clause introduced by a subordinating conjunction cannot stand alone as a sentence because it does not represent a complete thought. It depends on the main clause to complete its meaning.
