Venice(威尼斯) is a beautiful city in northern Italy. It’s very famous because it is built on many islands and it looks like it is built on water. There are 117 islands in Venice. Vince is famous for its architecture(建筑) and well-known people who were born there. One was Antonio Vivaldi.
Today, Venice has a big problem because it is sinking down deeper and deeper into the water. It is sinking down about 4 centimeters every 10 years. It doesn’t sound like much but it is a big problem because there are more and more floods(洪水) every year and people now have to use special wooden bridges to walk in the city.
