Hello,my dear teachers
I am glad to be here for this interview。
My name is Li Junhao (and) I'm 14 years old。I come from No。37 middle school of Xiangfan,(it is) a beautiful school。
At school,I am a good student,and English is my favorite subject。I have a great English teacher,（whose） very young and beautiful。She let(s) me feel the charm of english。
I like singing English songs,watching English movies,(and reading) E(n)glish articles (along with many other things related to English)。
（The reason I want to) participate in this competition is (because I believe this is the best way) to improve my English。(I also want to challenge myself and be able to feel) the atmosphere of the competition。I know (my English is not good enough at the moment),but (I am willing to try my best and put all my effort into this competition)
(不需要thats all)
Thank you。
