Good morning,ladies and gentlemen. (一般正式的场合要这样开头的,显得尊重对方)
I'm MaoYiChao, a pupil from the Center Primary School of GuanHaiWei town.
I love English because it make me happy. That's why I'm here. (用I'm here表示我报名参与)
I hope to make greater progress in English.
I'm willing to receive your instructions and advice.(直译是:我很希望得到大家的指导和建议)
