　　Snake poison

　　蛇毒

　　First listen and then answer the following question.

　　听录音，然后回答以下问题。

　　What are the two different ways in which snake poison acts?

　　How it came about that snakes manufactured poison is a mystery. Over the periods their saliva, a mild, digestive juice like our own, was converted into a poison that defies analysis even today. It was not forced upon them by the survival competition; they could have caught and lived on prey without using poison, just as the thousands of non-poisonous snakes still do. Poison to a snake is merely a luxury; it enables it to get its food with very little effort, no more effort than one bite. And why only snakes? Cats, for instance, would be greatly helped; no running fights with large, fierce rats or tussles with grown rabbits -- just a bite and no more effort needed. In fact, it would be an assistance to all carnivores though it would be a two-edged weapon when they fought each other. But, of the vertebrates, unpredictable Nature selected only snakes (and one lizard). One wonders also why Nature, with some snakes, concocted poison of such extreme potency.

　　In the conversion of saliva into poison, one might suppose that a fixed process took place. It did not; some snakes manufacture a poi...

　　The great escape

　　大逃亡

　　First listen and then answer the following quesion.

　　听录音，然后回答以下问题。

　　What is one of the features of modern camping where nationality is concerned?

　　Economy is one powerful motive for camping, since after the initial outlay upon equipment, or through hiring it, the total expense can be far less than the cost of hotels. But, contrary to a popular assumption, it is far from being the only one, or even the greatest. The man who manoeuvres carelessly into his 20 pounds' worth of space at one of Europe's myriad permanent sites may find himself bumping a Bentley. More likely, Ford Escort will be hub to hub with Renault or Mercedes, but rarely with bicycles made for two.

　　That the equipment of modern camping becomes yearly more sophisticated is an entertaining paradox for the cynic, a brighter promise for the hopeful traveler who has sworn to get away from it all. It also provides and some student sociologist might care to base his thesis upon the phenomenon -- an escape of another kind. The modern traveller is often a man who dislikes the Splendide and the Bellavista, not because he cannot afford, or shuns their material comforts. but because he is afraid of them. Affluent he may be, but he is by no means s...

　　Lesson 5 No Room in the Ark 诺亚方舟无容身之地

　　The gorilla is something of a paradox in the African scene. One thinks one knows him very well.

　　For a hundred years or more he has been killed, captured, and imprisoned, in zoos. His bones have been mounted in natural history museums everywhere, and he has always exerted a strong fascination upon scientists and romantics alike. He is the stereotyped monster of the horror films and the adventure books, and an obvious (though not perhaps strictly scientific) link with our ancestral past.(暂不提供全文)

　　Lesson 1 Finding fossil man 发现化石人

　　We can read of things that happened 5,000 years ago in the Near East, where people first learned to write.

　　But there are some parts of the world where even now people cannot write. The only way that they can preserve their history is to recount it as sagas----legends handed down from one generation of storytellers to another. These legends are useful because they can tell us something about migrations of people who lived long ago, but none could write down what they did. Anthropologists wondered where the remote ancestors of the Polynesian peoples now living in the Pacific Islands came from. The sagas of these people explain that some of them came from Indonesia about 2,000 years ago.(暂不提供全文)

　　Lesson 2 Spare that spider 别伤害蜘蛛

　　Why, you may wonder, should spiders be our friends ? Because they destroy so many insects, and insects include some of the greatest enemies of the human race. Insects would make it impossible for us to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for the protection we get from insect-eating animals. We owe a lot to the birds and beasts who eat insects but all of them put together kill only a fraction of the number destroyed by spiders.(暂不提供全文)
