Though water does not seem all that exciting, it is very valuable. The Ancient Greek people believed all the fresh water on the Earth came from a river called Okeanos. They imagined that clouds collected rain from its magical waters (海域). The reason they believed in this is because water is important for humans, Doctors say that without water we would die in about one week.
There are two places that our fresh water comes from. The first is surface water, which includes all the water in lakes or rivers. The second is groundwater, which refers to all the water that comes from under the ground.
Water must be treated before it can come out of the tap (水龙头). First, anything harmful in the water must be removed. Then a cleaning agent (净化剂) is added. This will destroy any remaining germs (细菌).
There have been reports of factories in China letting waste water leak into the ground. Industrial waste water is a big problem as it can pollute our drinking water. Even if the water is treated, it is unfit for drinking. The Ministry of Environmental Protection has improved the water in China since 2004. In 2011, 76 percent of water was safe for dinking. But treated water should always be boiled before drinking.
Some countries have more fresh water resources (资源) and this means that it is easier for them to treat their water.
A report from a British Consulting Firm called Maplecroft found that Iceland has the best fresh water supply in the world. That is because most of the tap water in Iceland comes from pure mountain springs. No treatment of any kind is required before Icelandic people drink their delicious water.

加拿大的史密斯先生昨天收到李明的一封信。
Mr. Smith in Canada _______________ Li Ming yesterday.
Long ago，as people got older，there was something wrong with their teeth and it would be very painful. To avoid a toothache，they had their teeth pulled out. Later people learned that cleaning their teeth was important，but they didn’t have toothpaste (牙膏) at that time. They used lemon juice，salt or other things to clean their teeth.
It was only about 100 years ago that someone finally created a mint (薄荷) cream to clean teeth. Not long after that，the toothpaste tube (管子) was invented，so people could squeeze (挤出) the toothpaste right onto the toothbrush! Tooth brushing became popular during the World War I. The U. S. Army gave brushes and toothpaste to all the soldiers，and they learned to brush teeth twice a day. Back then，toothpaste tubes were made of metal；today they’ re made of soft plastic and are much easier to use!
Today there are plenty of toothpaste choices：lots of colors and flavors (口味) to choose from，and some kinds of toothpaste are made just for children. When you’re choosing a kind of toothpaste，make sure it has fluoride (氟化物). Fluoride makes your teeth strong and healthy. When you brush，you don’t need a lot of toothpaste：just squeeze out a bit.
