问题     It is difficult to imagine what life would be like without memory. The meanings of thousands of everyday  perceptions, the bases for rite 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 of 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.
The whole passage implies that______.
选项 A、only human beings have problem-solving intelligence
B、a person’s memory is different from a computer’s in every respect
C、animals are able to solve only very simple problems
D、animals solve problems by instincts rather than intelligence
答案C
解析 推断题。本题问的是：整篇文章暗示出______。为了能找出本题的最佳答案，我们必须正确把握作者在文章最后一段第1句中想要表达的意思。“The use of words is the basis of the advanced problem solving intelligence of human beings．”此句的意思是“文字的运用是人类所具备的解决高级问题的智慧的基础。”它暗示出入类可以运用文字来解决一些复杂的问题，而其他动物却无法做到，因为一些动物只是具有低级的智慧，它们只能解决一些简单的问题。故选C。
