Dear my teacher(name)
i am very ashamed of not listening carefully to your class of english. yes I'm a slacker, but I want to change.Maybe it 's a tough and challenging job for me ,but I realise this was totally my mistask and i would stop playing mobile phone in your class and be more studious and hardworking in english studying.it's not irrealizable promise,i will make my promise come true.
I just want to ask you to forgive me because you have such positive effect on me ,without your helf i would never get proper education .I know i did wrong .
Sorry again
Yours sincerely

But this is not the end ,after that ,make sure that you do what you said you would do, and made a big change .
Dear English teacher: Iam so sorry that I have absented your English class for three times.But I am not quite myself then.I say sorry that I dont come to have the class.I am not deliberately. Ihave felt the strong sins now.That I want that you can give me another chance.Every student can be a deponent.that I will not do it again .IF I do it again,I will do as the teacher says.All things that I say come from my heart.please pardon me .Now I will say 'sorry,teacher,I will not do it again ' Thats all 祝你好运
Dear Miss Nancy,
Much to my regret I was unable to keep my promise to attend your birthday party last Saturday, owing to the fact that my little son was suddenly taken ill early that day.
Hoping to see you soon.
Truly yours,
Tom
