A、Human Basic Needs. B、Material Comfort. C、Food: Human Basic Need. D、Basic Necessities of Life. A主旨题。全文谈到了人的三种基本需求，所以A正确。B(物质享受)

We can agree with primitive man that food is a basic need, but we differ from him in our food wants because of the wide variety of food we have available compared with him; we have a wider choice. Take fruit for example, not only can we enjoy the fruits grown in his century, but because of modern methods of transport and food preservation, we can also enjoy more fruits from foreign countries, whereas primitive man is limited in his choice to the kinds of fruit which actually grow where he lives.
     However they differ in satisfying their hunger, primitive and civilized men both experience the basic need for food.
     The same is tree of the second of our human needs. Clothing is necessary to regulate the heat of our bodies. Since we live in a temperate climate we need more clothes than people living in tropical conditions. Likewise, our clothing needs to change with the seasons.
Shelter, the third of our needs, depends upon the climate, the skill of the builder, one’s social position, and the materials available. The simple shelter of primitive man would not do for us, and yet it satisfies his needs. The three- bedroom suburban house of the average family would not be grand enough for a rich family, and yet the modern house contains many of the material comforts which were denied to the Kings and Queens of old.
