Book or yours?

My favorite subject in school - is biology . in these lessons i sit and i think that i did not breathe . i'm afraid to miss some important word teacher. every time i look forward to the next lesson. i do not understand those who are not interested in this subject , because biology - the science about life , about us , about all living organisms. it explores the stages of development of living beings , sentient beings themselves , their interaction with the outside world . biology - the science of ancient as life itself . after all, to understand how to live - it was necessary to understand yourself , to find your place in this world , to understand how to interact with the world around them and keep yourself as a species. so the development of science was not only from curiosity , but also because of the need . so i carefully preparing for each lesson, i re-read a lot of literature and even signed up for extra classes . not because i have to catch up with the course or i have a bad performance , but because it is very interesting . i confess that i liked as much as biology in the eighth grade when we started to study human anatomy . perhaps it was due to the fact that her teacher taught us that he dearly loved this item . his lessons have flown as one instant .
