谁能帮我改一改,检查一下我这篇英语演讲稿的语法等信息,

Hello! My name is
Ben. I’m a junior secondary school student in Grade8 (中学不叫middle school那是中式英语). Small as my campus is, it supplys me a wonderful school life.
. My favourite subject is Physics. It’s amazing（very有点多余,amazing已经是语气很强烈的词了）. I enjoy (比like跟贴切)
Physical experiments. I am always be able to find some unusual things from experimenting.
I love badminton very much. So I think I’m a sporty boy. I believe （别老用think显得词汇匮乏)doing exercise
can keep fit. that's why I exercise for at least forty minutes a day. I have a broad range of interests(wide interest 估计很会让鬼佬们觉得疑惑).I also like traveling(逗号不能连接两个句子,用句号). I have been （不能加to） many
places. I even have been to Hong Kong Disneyland(看了下面老兄的回答,嗯,even是有点炫耀的意思). It’s a famous theme park and
includes four different parks——Main Street USA, Tomorrowland,Fantasyland and
Adventureland. I really enjoy my stay in Hong Kong. I hope I can visit there again some day. Thank you very much.
总体来讲语法没什么大问题,就是有些不地道表达,再就是使用了过多的“I”.另外就是有些句子过于简单,用鬼佬的话就是“baby talk”,虽然我也认为simple is the best,但是我觉得适当用几个略略复杂的句式可以使你听起来更成熟有水平,也能使句子的结构更为紧凑.通篇的简单句和一两句平列句有些过于简单.我指的就是后面的几句.还有就是结尾不太自然.
