Of all the things we eat and drink, water is the most important. Not many people understand this, but it is quite true. The human body can go without food for a long time, but two or three days without water usually make people dead.

Many people don’t know how much water the human body needs and they don’t drink enough, especially (尤其) in hot weather. Most people drink when they feel thirsty. They often need more water especially when they have sports.

A man’s body is 65 to 70 percent (百分之……) water. If we don’t have enough water, we may feel tried and may become ill.
