    Water is the most important of all the things we eat and drink. Not 1people understand this but 2 quite true. The human body can work without3 for a long time. We've got many examples for this. Yet two 4 three days without water can usually make people 5. Man can't live6water.

    A lot of people don't know how 7 water the human body needs to work well, and many people, especially the young, do not drink enough water, 8in very hot weather. About 70% of the human body is water. That is to say about two thirds of our body9 water. When we do sports, some of the water will get away from our body. 10 we don't drink enough water, we may feel tired and many of us will get ill. So you know how important water is to us.

    There are many different kinds of museums in the world. But have you ever visited a museum of tap water? Beijing Museum of Tap Water may be the only one in the world.

    The museum has a large number of photos, models, maps and equipment which tell the water treatment history of China. Few of them are in English, so it's a bit difficult for foreign visitors to understand them.

    Beijing's tap water history began in 1908.  At that time Empress Dowager Cixi(慈禧太后) ordered to build water plants and city pipelines to help fight fires that happened in Beijing.

    At first, people did not believe in tap water. They continued using well water(井水) which was not safe. Later, the government did everything to explain to people how safe tap water really was. Finally, more and more people started using tap water.

    The museum is one of the most wonderful places in Beijing. For those who want to try something different, this place near the Dongzhimen Subway Station is a very unusual one.

    There are too many cities around the world. And each city needs water in many ways. Water on the Earth falls mainly as rain. So the rainfall（降雨量）is important to each part of the world. And it is different from one city to another. The following chart shows the average(平均的）rainfall in four different cities in July and January.
