如果看不懂的,可能是我打错了。只要大体意思对就可以了。
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 tow or three days without water usually make people dead.
Many people don’t understand how much water the human body needs to work well and many people do not drink enough, especially in hot weather. Most people drink when they are thirsty, but they often need more water especially when they take exercises.
A man’s body is 65 to 75 percent water. If you do not have enough water, you feel tired and may become ill.
