请帮我改一下这篇英语文章，拜托，急！！！！！上海世博带给我许多

首先 第一句中的“bring ” 要改成“brings”用 第三人称
第二，“two thousand and ten Shanghai ”可以直接用阿拉伯数字 没有外国人会写一大长串的哦 直接2010就行了
第三，第二行中“Shanghai world expo held in China” 应该是被举行 所以应是 was held in china.
第四，“It iet us know that we have lots of proble now”改成“it makes us konw that we ourselves have lots of problem "
哎呀 我都无语了 我直接把改好后的文章写在下面 你自己看看错在哪里
Shanghai brings me a lot
Everybody knows that the 2010 shanghai world expo was held in china . It makes me know that we ourselves have lots of problem and how important it is to protecet the environment.
The shanghai world expo not only promoted the development of economy and,international cooperation and the domestic infrastructure construction but also a great opportunity to show chinese civilization.
The world expo lets me understand how to protect the environment.For example ,we should be a good citizen and never spiltting or littering.
let us work together to make our city more beautiful!
that's all. thank you for your listening!
