Being a self-taught English instructor, I must keep myself informed with pertinent information and the most up-dated styles in English writing at all times, which is why I've decided and then joined this "Knowledge-sharing" site. Offering my English ability and proficiency to help people solve their thorny problems of various natures is, at least the way I think, a pleasure I can afford. Therefore, whenever I have enough free time besides mymain job, which is teaching various levels of English programs both at school and at some reputed cram schools for higher education, foreign studies, and employment-oriented purposes, and my major hobby, riding super-heavy class motorcycles around town and country, I'd be willing to offer more here. OK, I think time, effort and patience will eventually pay off at the end for all of us interested in learning better English. Wish you all the best and keep in touch.
