Wild animals (and wild plants) and the wild places where they live are seriously threatened almost everywhere. One species has become extinct in each year of this century. But many hundreds are now in danger. Lack of attention would lead to the rapid advance of the process of extinction.
Already many kinds of wild animals have been so reduced in number that their role in the ecosystem is forgotten. Animals like the great apes, the whales, seals etc. thought to be in danger of extinction.
But even more important, perhaps than individual kinds of animals and plants, whole habitats are in danger of vanishing: marshes are being drained, and the world forests, especially tropical forests are being cut down to satisfy man’s needs of timber and paper.
What would our world be like if all the wild animals and wild plants vanished? - Would our life still exist then?
1. What would happen to the human beings if the wild life vanished?
A. Many species would quickly become extinct.

Read the passage carefully, then choose the correct answer
The first system of communication of animals is natural. Many kinds of animals have ways of communicating with each other. And one of the most interesting examples is that of bees. These insects communicate with each other by dancing. The most important kind of dance that they do is concerned with food. They get their food from flowers, of course, from plants and trees. When a bee has found some food, it returns to the other bees and can give them three basic kinds of information about the food: which direction it is in, whether it is nearby or a long way away, and whether it is good to eat or poisonous.
The other kind of system of communication of animals is artificial. It means animals learn it; in this case, they learn from man. Several famous experiments have been carried out with chimpanzees, trying to teach them human language.
One of these experiments was done with a chimpanzee called Sarah. Sarah was taught to understand a system of symbols which represented words. The symbols were cut out of coloured plastic, and each different shape stood for a different word. For example, a red square stood for “banana”, Sarah’s favorite fruit. Soon Sarah could not only understand words, but even sentences. She could obey orders: if her human friends put down the symbols for “apple in cup”, she would put the apple in the cup. Later, she began giving the scientists orders – she was writing her own sentences, and she got upset if the scientists did not obey her. We do not yet know whether chimpanzees will ever learn to use language to communicate as freely as human beings do, but the results so far suggest that this is at least a possibility.

43) The experiment done with Sarah is an example of ____________________.
A. animals with natural system of communication
B. animals able to communicate with humans
C. animals possible to use language as humans
D. animals with a system of communication worked out by humans
44) The results of the experiment with chimpanzees show the possibility to teach animals _____.
A. how to use language freely
B. how to give orders
C. how to obey orders
