女生染黑色头发显老吗?:简单的英文自我介绍

My name is Li Yang.I graduated from Lanzhou University and majored Mechanical Engineering.I was once a poor student of English,and it was my biggest headache and trouble-maker.I got sick and tired of learning boring grammar rules and lifeless words.But through hard work in practicing speaking English and breaking away from the traditional grammar games,I found myself a totally different and exciting new world.Not only did I pass Band four and Band six College English Exams very easily with high marks,but importantly,I began to use English.
Finally,I developed a new Language Cracking System myself,I began to teach German not long after I started to learn this terribly difficult language in my own way.It was a miracle but I made it.To speak good English,I think one year of study should be enough for any dilligent and interligent person.
I'd like to share my learning techniques with you,and I will be very glad to answer your letters and be your friend.
