Changzhou has a long history of more than 3,000 years. It’s home to manyfamouspeople, like Liu Haisu and Zhou Youguang. Hua Luogeng also comes from Changzhou. He lives in Jintan, an area of Changzhou for a long time. He is famous for his study in maths.

Changzhou is in the south of China and it’s a water town（城镇）. There are lots of lakes and rivers, so you can see many boats. You can find lots of old houses there too. Food in Changzhou tastes great and the people there are kind. I like the food and the people in Changzhou.

The best time to visit Changzhou is in spring and autumn. During the time, the weather is nice and the scenry（风景）is the most beautiful.

Bern is the capital of Switzerland. It is in the west of the country. It is pretty quiet there. Geneva and Zurich are two important cities in Switzerland. Geneva has a long history and Geneva Lake is very beautiful. Zurich is the largest city in Switzerland and the financial capital of the country. There are also some lakes in Switzerland and its tourists can travel between towns by boat.

Venice is the “Queen” of the Adriatic Sea. Every year many people from all over the world visit the city. Do you know why they like to travel there?

Venice is a very beautiful city. It is quite different from other cities in the world. There aren’t any roads or streets in the city. So there aren’t any cars or buses. There are many canals in the city. There is one big canal and 177 small canals. People move up and down the canals in boats to go to work, go shopping or visit their friends.

But Venice is sinking(下沉). It is going down and the water is going up. In 2040 Venice will be under water. The Adriatic Sea will cover(覆盖) the city. The Venetians love their city and want to stay there. They do not want to leave. So they want to save(拯救) Venice from the sea. How can they save Venice? They can build some strong big walls and gates in the sea. The gates will close to keep too much water out. In this way Venice will not sink.
