One possible version:

"One World, One Dream" is the simple but meaningful slogan adopted for the Beijing Olympic Games.

It fully reflects the Olympic spirit and highlights the theme that the whole mankind lives in the same world

and seeks for the same dream and ideal. Qinhuangdao is a city to host some of the football events of the

Olympics. That's why the slogan is frequently seen there.

People throughout the world live together like members of a huge family, sharing the same home, the

earth. It is everyone's dream to build our world into a paradise, where there's no poverty, no disease

and no war. To make the dream come true, we should make common efforts to protect the environment,

develop science and technology, and promote international friendship. When people from all over the

world come together for the Beijing Olympics, we're actually stepping forward towards the realization

of that shared dream.
