感谢逸老师修正My Bad Teeth小文!周末愉快!:)回头再来学习这篇。
Years ago back in Toronto,THAT WAS one year before my graduation WWHEN I decided to receive the orthodontic treatment IN a dental clinic , because my bad teeth really bothered my self-confidence. ..... Every time when I got the urge to smile I would cover my mouth because I hateD to show my flipped-over-backwards-inside-out looking teeth.
