我有一篇英语作文,不知道够不够1分钟演讲,而且有蛮多语法错误,

1.第一句跟第二句的意思是一样的,可以省略其中一个.
2.通常演讲前面可以加个“Good morning / afternoon,everyone.等开场白,演讲结束加个结束语,如That's all.Thank you.
3.根据你要表达的大概意思,我帮你修改一下语法方面的问题,没有使用很多从句,基本是保持原来的简单句式.
4.一般按照匀速的话,表达出来,大概就一分钟左右吧.
Good morning,everyone.It’s my pleasure to introduce myself to all of you here.My name is XXX.I am a fanciful girl who always have many wonderful dreams.Sometimes,I would like to travel around the world,sitting on the clouds.Sometimes,I want to become a witch so as to steal the spell of black cat.Sometimes,I want to have the same speed as the vampire.
I have hundreds of dreams,most of which probably won't come true.However,I also have a very realistic dream.I want to be invigorating,like the pianist.(其实精力充沛跟钢琴家没有什么必然的联系吧?如果是要表示充满活力的,可以用energetic ,更简单点）
I have been playing the piano since I was little,hoping that one day,I can have a concert held in Provence.I am also in the hope that one day,I could own a piano which is the same as theirs.But my parents always say," Do not think about irrelevant things.Study is the most important." What they say really discourage me.
I hope my parents can give me more free space.They should allow me to schedule the time by myself,which can make me mature.And this is my biggest wish.I do hope someday in the future it can come true.
That's all for my speech.Thank you for listening.

第二句跟第一句重复了， I would like to travel around the world sat on the clouds; 中的sat 改为sitting。Studied piano since I was little改为Having studied....
