Because we are different from others,so the world will become so beautiful.這是個錯句的,不能加so.
我們和別人不同（應該是我們之間不相同吧：所以應該說：Because we are different from each other,)
We are different from others.The world will become so beautiful.
應該說：
We are different from each other.The world will become so beautiful.(這句話是中式英語,前者為一般現(xiàn)在時,后者為一般過去時,不太合適的）
我的譯文：
It is the differences between us that make the world become so beautiful.
就是我們之間的不同使這個世界如果美麗.（強調句的）
