Question

 (05·湖北E篇)

From the moment that an animal is born it has to make decisions . It has to decide which of the things around it are for eating , and which are to be avoided ; when to attack and when to run away . The animal is , in fact , playing a very dangerous game with its environment , a game in which it must make decision—a matter of life or death .

Animals’ ability to act reasonably is believed to come partly from what we may call “genetic (遺傳性的)learning” , which is different from the individual (個體的) learning that an animal does in the course of its own lifetime . Genetic learning is learning by a species —animals of the same kind—as a whole , and it is achieved by selection of those members of each generation that happen to act in the right way . However , the role of genetic learning depends upon how similar the future environment is to the past . The more important individual experience is likely to be , the less important is genetic learning as a means of getting over the problems of the survival game . Because most animals live in ever changing evironments from one generation to the next , it is not surprising to find that very few species indeed depend wholly upon genetic learning .

In the great majority of animals , their particular ways of acting in a new environment are a compound (復合體) of individual experience added to the action patterns animals are born with .That is why animals can survive .

       A．if the animal makes a wrong decision    B．if the animal plays a dangerous game

       A．each generation has its own way of learning

       B．their environments change all the time

       C．they can act reasonably on their own

       D．it takes their whole life to learn

74．When the environment doesn’t change much ,         .

       A．a(chǎn)nimals cannot act in a right way

       B．genetic learning is less important for animals

       C．individual learning plays a less important role

       D．a(chǎn)nimals cannot get over problems on their on their own

75．Animals’ living on generation after generation depends on          .

       A．their natural action pattern with their own experience

       B．the lessons they have learnt during their lifetime

       C．their experience in particular environments

       D．the knowledge passed on by their parents
