300年前，上海只是个小镇，只有几千人居住在这里，其中很多人是渔民和农民。

Today, Shanghai is becoming an international city. Many tall building have been built. Some bridges have been put up over the Huangpu River. More and more foreigners come to Shanghai for a visit every day.

今天，上海已变成一座国际大都市，并建成了很多高楼大厦。黄浦江上架起了很多桥梁。每天都有越来越多的外国人前来旅游。

Shanghai has already won the bid for holding the World Expo 20xx. I think the environment will be better and better and the city will be more and more beautiful.

上海已经取得了20xx年世博会的举办权，我相信上海的环境会越来越好，并且越来越美丽。
