英语好的帮帮忙啊！！

I used to go to circus to see magician playing magic tricks with my dad when I was little. At that time, I appreciated so much and enjoyed them. I was always amazed by how they cut a people halfway who's inside a box without hurting him, and how they make people float in the air. The most popular magician in my opinion is David. He always has the most amazing tricks ever. For example, we see him flying on the stage without the help of any mechanisms which is dreamed by people for centuries. However, I know the tricks are not real, but I still like it.
我小时候经常和父亲一起去马戏团看魔术师表演魔术.那时,我很欣赏和喜欢魔术.我经常惊叹于魔术师们是如何切断一个在箱子里的人而不让他们受伤,或者他们怎么让人们漂浮在空中.最受欢迎的魔术师应该是大卫了,他能表演最让人惊奇的魔术.比如我们能看到他在不受任何帮助的条件下飞翔在空中,这个是被人们梦想了好多世纪的.但是,我知道魔术不是真的,可是我还是很喜欢魔术.

现在， 魔术非常流行。我不是魔术师，但我能变魔术。

首先， 找一个硬币。然后对着一个人说：我可以把硬币吃下去再从背脊里拿出来。 同时，开始魔术表演。说“吃”后， 假作把硬币吃进肚子里面， 并做些假动作来掩饰。说“从背脊里拿出来”后， 把硬币从背后拿出来。如果你理解，这个魔术就会很简单。
