描写老师的英文短文

my english teacher is an old woman, most guys in our class were afraid of her, because she seemed very strict. everytime when she came to our classroom, we'd become quiet, no one dared to say a word on her class. but one day she told us a story, it was about her former student, and from then on we knew that she's a kind lady and takes much care about us in fact. we felt shame about what we thought about her before. we have become more active on her class now, and our english progressed quickly. we love her much more than before.
