An uncommitted crime
On October 19, 2010, the day that I will never forget, I was unjustly accused of stealing my colleague's necklace. After finishing the three hours of the novel lecture, the girl, who was sitting beside me, shouted, suddenly, because she had lost her necklace. All of us, immediately, separated everywhere in the room in order to search for her necklace. During the time that I was searching with my friends, my sister called me and informed me that my mother got sick and I had to come now. At this moment, I was very embarrassed; I took my needs rapidly and left the room without telling any single word. When I went home, I found that my mother was, really, in a very bad state, and the doctor told me that she was in bad need for someone to take care of her. I, therefore, had to stay with her, and I did not go university three days ago until she became better. In the fourth day, when I went to my faculty in order to attend my lectures, as usual, I found that all my colleagues looked down upon me. In fact, I was surprised from the way they treated me, but when I met Ann, the necklace's owner, and asked her about her necklace, she alluded immorally that I was the one who stole her necklace. I swore at her that I did not take her necklace, but she did not believe me. She told me that I was the only one who sat beside her and left the room during the time they were searching for the necklace. Although I told her what happened to my mother, she did not believe me. In fact, I did not bear the way they treated me; therefore, I decided not to go the faculty any more in order not to see any one of them. Actually, I was forced to pay a price for a crime which I did not commit.

Hello, Greece-- and welcome to English Forums. You have far too many commas. I have underlined some problem areas:

thanks very much for your editting, but can you tell me what is the problem with:
novel lecture,
go the faculty
alluded immorally

did not bear
went home
Students: We have free audio pronunciation exercises.
novel lecture -- a strange lecture? I think you mean 'a lecture on the novel'.

go the faculty-- 'faculty' seems the wrong word[[ that is usually a body of professors. You probably went to the 'department'.

alluded immorally-- Oh dear! Please look up 'immorally' in your dictionary. The girl wasn't a prostitute, was she?

did not bear --'could not bear' or 'did not like'.

went home -- 'came home'.
OK I UNDERSTOOD YOUR POINT, but
i show you some points
first of all, illuded immorally
the word immorally does not only have the meaning that she a prostitute, but this word have an athor meaning which is the way that people behave; foreexample, it's immoral to steal
Second, novel lecture i want to define the subject we were taking at that time.
Thanks for the rest of mistakes . i really understood them ang i agree with you
I neither wish nor need to argue with you. My English is much better than yours: that's why you have come here for advice. If you do not wish to accept the advice given, then just ignore it.
Students: Are you brave enough to let our tutors analyse your pronunciation?
Thank you

The words that contain errors are bracketed and correction are mentioned and seperated with a slash. The left side of the bracket is your error while the right side of the bracket is, I assume, the correction. Maybe some professional will give you a more sophisticated answer. Hope this helps.

Emotion: smile

thanks again for using words like:lashed out; 'allegedly'
