THANK YOU!!!!!!!!
There are many mistakes here, mostly of usage. I will address the major problems here.

First sentence: a teen have benn victim of a short missed ,then he tried to kill his agressor,he had a feud with the two boys.

Let's correct the spelling first:

A teen have been victim of a shot missed, then he tried to kill his aggressor, he had a feud with the two boys.

Here, have been does not agrees with the subject. In order to agree with the 3rd person singular noun teen, have been must become has been.

A teen has been victim of a shot missed, then he tried to kill his aggressor, he had a feud with the two boys.

Now let's look at the tone of the sentence. When you use a construction like has been, you are usually talking about some past event--you really are not concerned with the event itself, just that it has happened. Here, however, you are describing a specific event. You will want to point to that past event with a verb in the simple past (we'll add the proper article, a, for good measure:

A teen was a victim of a shot missed, then he tried to kill his aggressor, he had a feud with the two boys.

Now you have a complete sentence up to the underlined portion. The underlined portion should be a separate sentence because it is a separat thought and includes its own subject and predicate:

A teen was a victim of a shot [that] missed, then he tried to kill his aggressor, He had a feud with the two boys.

These sentences are now complete and correct.

Here is the rest with the errors underlined:

For the principal who try to make her life bettter , the solution isn't it police but more discussion, help and hope.she says that apathy and rage are the enemies of children not knives an guns

And corrected for spelling, verb tense and agreement, and usage:

For the principal who (tries / is trying) to make her life better, the solution isn't [more] police, but more discussion, help, and hope. She says that apathy and rage are the enemies of children, not knives and guns.

To may want to look at your other compositions in the same way. Don't look at the work as a whole, but separate the parts of the task of correction and perform each task separately (correct the spelling, then correct verb tense, etc.)

Please check post no. 198597 in the thread http://www.EnglishForward.com/English/TellMistake/bpwvz/Post.htm by Silversamand. He/she is not the one asking the question, and the "solution" provided is a complete mess with regard to spelling and grammar.

Thanks!
