Flying over a desert area in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour’s flight one of the scientists wrote in his book, “Look here for probable mental. ” Scientists in another airplane, flying over a mountain region, sent a message to other scientists on the ground, “ Gold possible”. Walking across hilly ground, four scientists reported, “This ground should be searched for metals. ” From an airplane over a hilly wasteland a scientist sent back by radio one word, “Uranium”

  None of the scientists had X-ray eyes; they had no magic power for looking down below the earth’s surface. They were merely putting to use one of the newest methods of locating minerals in the ground―using trees and plants as sighs that certain minerals may lie beneath the ground on which the trees and plants are growing.

  This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow on the surface.

  At Watson Bar Creek, a brook six thousand feet high in the mountains of British 39, however, one tends to believe fully in the reality of the dream world, Columbia, Canada, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug and put into boxes. Each bag and box was carefully marked. In a scientific laboratory the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it.

  Study of the roots, branches, and seeds showed no silver. But there were small amounts of gold in the roots and a little gold in the branches and seeds. The seeds growing nearest to the tree trunk had more gold than those growing on the ends of the branches.

  If the tree had not indicated that there was gold in the ground, the scientists would not have spent money to pay for digging into the ground. They did dig and found more gold below. They dug deeper. They found large quantities of gold.

  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.

 

66. According to the passage, memory is considered to be ________.

A. the basis for decision making and problem solving

B. an ability to store experiences of future use

C. an intelligence typically possessed by human beings

D. the data mainly consisting of words and combinations of words

67. The comparison made between the memory capacity of a large computer and that of a human being shows that ________.

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

68. 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

69. The phrase “in terms of” in the last sentence can best be replaced by ________

A. in connection with                         B. expressed by

C. consisting                                     D. by means of

70. The topic of the passage is __________.

A. What would life be like without memory?

B. Memory is of vital importance to life.

C. How is a person’s memory different from an animal’s or a computer’s?

D. What is contained in memory?
