It is difficult to imagine what life would be like without memory. The meanings of thousands of everyday perceptions, 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 involving 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 for 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 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 basis of 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. [br] The comparison made between the memory capacity of a large computer and that of a human being shows that______.
选项
A、the computer’s memory has a little bigger capacity than a teenager’s
B、the computer’s memory capacity is much smaller that an adult human being’s
C、the computer’s memory capacity is much smaller even than a teenager’s
D、both A and B
答案
C
解析
根据文章的第三段提到的“The instant—access memory of a large computer may hold up to 1 00,000“words”一ready for instant use.An average U.S.teenager probably recognizes the meaning of about 1 00,000 words of English.However,this is but a fraction of the total amount of information which the teenager has stored."可知,一台大型计算机的存储器可以容纳多达10万个单词;而一个普通的美国青少年可能也会认识大约10万个英语单词的意思。然而,10万个单词只是一个青少年全部记忆储存的一小部分。所以,计算机的记忆储备量要比一个十几岁的青少年的记忆存储量小得多。这个比较是在计算机和青少年之间进行的,与成年人无关,故选C。
