听力原文： 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 the more fruits from foreign countries thou- sands of miles away, 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 true of the second of our human need. 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 tropic conditions. Likewise, our clothing needs to change with 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.

Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
Running a lever was once thought to be the prerogative of warm-blooded creatures, whose internal temperatures are independent of the weather. But, as Matthew Kluger reported in "The Importance of Being Feverish" (January 1976), lizards can also develop fevers, even though there is no question that they are cold-blooded. They raise their temperatures by moving into the sun or, in the case of Kluger's experiments, under a sun lamp. And it seems to do them some good. Sick lizards kept in cages at feverish temperatures fare much better than their counterparts in normal mid cool environments.
Now, fever has spread to invertebrates(无脊椎动物). Recent studies have shown that crayfish and scorpions can develop fevers. Crayfish injected with bacteria and scorpions injected with prostaglandins(前列腺素) swam and scuttled to hot areas. (Prostaglandins are hormones thought to be instrumental in the development of a fever. )
Evidence is also mounting that moderate fevers have their benefits, which might explain why the fever process is so widespread. Leukocytes, white blood cells that are active in fighting bacterial infections, are more mobile at febrile temperatures. And fevers reduce the amount of iron available to bacteria. That reduction, combined with high temperatures, has been shown to inhibit bacterial growth.
