Peace be upon you....

The simple sentence contains one subject and one finite verb, it is a finite clause that stands alone

So, the bellow sentence contains more than one finite verb, but my teacher considered it as a simple sentence and she told me that we've one subject

*He changed the oil and washed the car

so since it contains more than one finite verb, it is rather a compound sentence

What do you think?

Thank you ; )

 
Husam,  

  Thank you so much  for your answer
I see what you mean but if we agree that it is a simple sentence, we'll be in contradiction with the definition of the simple sentence

All the best for you

Hello dear, I found this explanation that may help you   :

This means that "Simple Sentence" may contain "Compound Verb" or "Compound Subject" but it differs from "Compound Sentence" …..

Compare….

 
SIMPLE SENTENCE

A simple sentence, also called an independent clause, contains a subject and a verb, and it expresses a complete thought. In the following simple sentences, subjects are in yellow, and verbs are in green.  

A. Some studentsliketo study in the mornings.
B. Juanand Arturoplayfootball every afternoon.
C. Aliciagoesto the library and studiesevery day.

The three examples above are all simple sentences.  Note that sentence B contains a compound subject, and sentence C contains a compound verb.  Simple sentences, therefore, contain a subject and verb and express a complete thought, but they can also contain a compound subjects or verbs.

COMPOUND SENTENCE

A compound sentence contains two independent clauses joined by a coordinator. The coordinators are as follows: for, and, nor, but, or, yet, so. (Helpful hint: The first letter of each of the coordinators spells FANBOYS.) Except for very short sentences, coordinators are always preceded by a comma. In the following compound sentences, subjects are in yellow, verbs are in green, and the coordinators and the commas that precede them are in red.

A.  Itriedto speak Spanish, andmy friendtriedto speak English.
 
B.  Alejandroplayedfootball, soMariawentshopping.
 
C.  Alejandroplayedfootball, for Mariawentshopping.


The above three sentences are compound sentences.  Each sentence contains two independent clauses, and they are joined by a coordinator with a comma preceding it.  Note how the conscious use of coordinators can change the relationship between the clauses.  Sentences B and C, for example, are identical except for the coordinators.  In sentence B, which action occurred first?  Obviously, "Alejandro played football" first, and as a consequence, "Maria went shopping.  In sentence C, "Maria went shopping" first.  In sentence C, "Alejandro played football" because, possibly, he didn't have anything else to do, for or because "Maria went shopping."  

 
Ranaa,  
Husam,  
Many thanks to all of you
Me too I've already seen that website
but what is confusing to me is  that some teachers insist that if we consider a sentence as a simple one, it should have one finite verb ,so, if not it is a compound sentence
Best wishes
