When we speak of a basic human need we mean something necessary to life, something we cannot do without. Food is a basic human need. Without it we would starve to death. Whether in primitive(原始的)countries or in more advanced societies, man’s food needs are the same.     2    
But primitive people eat only the food which can be grown near their homes, whereas people in more advanced societies eat food which is often grown many thousands of miles away from their homes. Primitive people are satisfied with less kinds of food, therefore we can say people’s wants are different although their needs are the same.
    3     Clothing is necessary to regulate (调节) the heat of our bodies. In different climates and in different seasons we need more or less clothes. We also dress differently for other reasons.     4    
Shelter, the third of our needs, depends on climate, the skill of the builders, one’s social position, and the material which can be used.     5     The three-bed-roomed house of the average family would not be grand enough for a very rich family, but a modern house with many of the material comforts were denied to the kings and queens in the past.
