English Class

Today I was nervous in during my English class because the teacher said that we have to talk speak in front of alleveryone . My pronunciation is not good I have not a good pronunciation and to be honest, my English is not the best. I was afraid because my classmates speak very well and they  always are laughing when you someone has bad pronunciation pronounce bad. I didn't participate because the class ended finished, but tomorrow I'm gonna going to do it. I have to be brave, I mean, if I know am aware of about my mistakes I'm gonna going to improve.

Hi Lourdes! My advice is that you should learn to laugh at your own mistakes, because the students who don't make any mistakes aren't taking enough risks, but those who make the most mistakes are the successful ones in the end. By the way, what kind of pronunciation problems are you having?

As far as your notebook entry -- Everything you wrote could have been written by a native speaker; the problem is, it looks like it was written by many different native speakers. What I mean is, it's not consistent in style.. formality, dialect, etc. Also, there are some phrases that are not errors, but are rather unusual "they always are laughing" and other phrases, that are usual, but technically incorrect (like using "bad" as an adverb). Also, "gonna" is the most common pronunciation in spoken English, but should be written as "going to." I've re-written your paragraph in a consistent, natural American style:

Today I was nervous in (it's not incorrect to say "my," but it's unnecessary) English class because the teacher said that we had to talk in front of everyone. I don't have (in British, you could say "haven't" and in both British and American, you could say "haven't got) a good pronunciation (or "My pronunciation isn't that good) and to be honest, my English is not the best. I was afraid because my classmates speak very well and they are always laughing when you pronounce badly (or "... when you make pronunciation mistakes). I didn't participate because the class finished (or "ended." A typical expression would be "I was saved by the bell"), but I'm going to do it tomorrow (I moved "tomorrow" to the end for emphasis -- optional, but a nice technique). I have to be brave, I mean, if I know about my mistakes (or better, "if I have the opportunity to make mistakes and get corrected") I'm going to improve.

Be brave, Lourdes. In my experience, the other students are almost as nervous as you are, and they'll be too busy worrying about their own mistakes to pay attention to you.
