英语改错,找出10个错误
I am so exciting that i can't wait to share with you what i experienced today.I gave my first lesson in our school.which left me the deep impression.When i entered into the classroom,my students began to make much noise.I stood on the platform,knowing what to do at first.But soon I realized everything must be done.I asked the kids that they liked English songs.They all say "Yes" .I sang a song I had practised many times.To my great surprised,all the kids turned their attentions to my class.From this experience I know however happens,we must stay calmly first and find a wise solution.
