Green gang jokes.

My English is poor, but I tried my best to give you a wonderful speech, so I spent a lot of time preparing. Although the lecture lasted only one or two minutes, it was a great challenge for me. To be honest, this is the first time for me to speak English in front of so many people. So, if there are any mistakes, please forgive me. I am a senior high school student in Grade Two. I realize the importance of time. I will study harder in the future. I think everyone has the same idea.
