求 change the unchangeable为题的三分钟英语演讲稿.

Hello all.
I would like to about the title "change the unchangable".
As of today,the scientific development is on a very fast pace.
We are in a quite comfortable mode in our day life.
In order to surplus the current situation or to be better,we need to make improvemet.
We need to make change.
As mentioned above,minor improvement will just result in a small change with small return.
Thus,the small return will not be able to meet the people's need today
We need to make huge step to get more advancement.
Under this circustance,we need to make big change and we need make to change the unchangable,the things that others think that is could not be changed.
Just an example,iphone.
Do anyone imagine the smartphone looks like today before the iphone was launched?
previouly,everyone thinks that the phone is just a tool to make call,to receive message.
But nobody think of internet surfing,phone pocket money etc.
Till our great genious,Job Bruce came out with the great idea of iphone.
He finally made a product,that change the people's mind about phone.
He changed something that is unchangable and therefore he is sucess.
In short,in order to achieve success,we must always be ready to change the unchangable
