hello ..
I'm writing about the special teacher that too deserves to win this year
As she was my teacher i want to say thank you for her about her helping me from my first year in high school. And i like to say she’s an excellent teacher .
The award should be given to her because she is hard-working and helpful for the new students because she’s explain every things in language the student will understand quickly.
Why i I chose her my special teacher! Because she’s help me a lot in my English class and explain the work clearly and in easy way. Also she helped me with my school timetable and my class rooms.
The special about her that she’s good at dealing with new students, especially for those who do not speak the English language very well.
