Just a few remarks on the previous correction:

-  lauanages --> languages

-  For example, my older brother... --> Another example of people knowing a different language is my older brother, who can translate French articles.

- I had admired him. --> "I admire him. " or "I've always admired him." since the action is still continuing.

-  I think it's unnessary -->  I think it's unnecessary

- I want to speak this language fluently as they do --> I want to speak English as fluently as they do

- in the furture. --> in the future.

My Dream

I'm 17 years old, and  I have a dream. I want to travel around the world. I want to study different kinds of lauanages. In fact, I have had heard seen many people speak English fluently cily. For example, my older brother can translate French articles  artcile .I had admired him. and. I think it's unnessary to do the same thing as  like others, I want to speak this language fluently as they do  fluencily lauanage as like them.and I think I will realize my dream as soon as I do my best. i wish i I hope I will succeed successed in the furture.
I think I am like a liked the Witch .I will realize my dream. Come on.
