     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 (遗传性的)
learning", which is different from the individual (个体的) 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 environments 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
(复合体) of individual experience added to the action patterns animals are born with.That is why animals
can survive.

1. The animal's life will come to an end _____.

A. if the animal makes a wrong decision

2. Very few species depend entirely on genetic learning because _____.

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

3. When the environment doesn't change much,  _____.

A. animals cannot act in a right way
B. genetic learning is less important for animals
C. individual learning plays a less important role
D. animals cannot get over problems on their on their own

4. 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
