我有一个梦不会变，，英语怎么说？

我觉得用被动语态比较好，因为梦想是被改变。原句可能也可以，不过逗号后加个and更好
I have a dream, and it won't be changed. (不用被动语态应该也可以吧）
也可以用定语从句 I have a dream which will never be changed.

i have a dream, and i am not planning to change it

I have a dream that will never change.

I have a dream that never changes.
I have an unchangible dream.
I have a dream that lasts forever.
