I haven't seen Mr Jenkins since I finished school, but I often think about him. I wasn't very good at school subjects before I(遇到) Mr Jenkins. I suppose I was a bit lazy, (尤其) in science. But everything changed when I went into Mr Jenkins' class at the age of (十五).
Before Mr Jenkins taught me, science had simply been a subject ( 充满) of strange words to me. I didn't know what oxygen was. And I didn't really want to know, (也). I found it so boring and difficult. But Mr Jenkins made everything interesting. He used to explain things which seemed difficult with lots of easy (例子) and in simple words. He even asked us to build a rocket by ourselves!
I wasn't an (积极) student, but I wasn't slow to learn new things. The problem was that I was not confident in (我自己). Mr Jenkins made me feel that I had my own advantages. He once asked me to give a presentation about stars and planets to the class. I had never done that before. And now it's my job! When I'm(准备) a class, I often think about how Mr Jenkins would do it. I hope I can always have the(机会) to ask for his opinion!
