何谓经济杂交？

阅读理解。

     It is difficult to imagine what life will be like without memory．The meanings of thousands of

everyday perceptions(感觉、知觉), the bases for the decisions we make, and the roots of our

habits and skills are to be found in our past experiences, which are brought into the present by

memory．

     Memory can be defined as the capacity to keep information available for later use．It includes

not only "remembering" things like arithmetic or historical facts, but also involves any change in

the way an animal typically behaves．Memory is involved when a rat gives up eating grain

because he has sniffed something suspicious in the grain pile．Memory is also involved when

a six-year-old child learns to swing a baseball bat．

     Memory exists not only in humans and animals but also in some physical objects and

machines．Computers, for example, contain devices from storing data for later use．It is

interesting to compare the memory-storage capacity of a computer with that of a human being．

The instant-access memory of a large computer may hold up to 100,000 "words"-ready for

instant use．An average U．S．teenager probably recognizes the meaning of about 100,000

words of English．However, this is but a fraction(部分、片断) of the total amount of

information which the teenager has stored．Consider, for example, the number of faces and

places that the teenager can recognize on sight．

     The use of words is the advanced problem-solving intelligence of human beings．A large

part of a person's memory is in terms of words and combinations of words．

A．the basis for decision making and problem solving

A．the computer's memory has a little bigger capacity than a teenager's

B．the computer's memory capacity is much smaller than an adult human being's

C．the computer's memory's capacity is much smaller even than a teenager's

D．both A and B

3．The whole passage implies that _______．

A．only human beings have problem-solving intelligence

B．a person's memory is different from a computer's in every aspect

C．animals are able to solve only very simple problems

D．animals solve problems by instincts rather than intelligence

4．The topic of the passage is __________．
