单选题"Equal pay for equal work" is a phrase used by the American women who feel that they are unfairly treated by society. They say it is not right for women to be paid less than men for the same work. Some people say men have more duties than women. A married man is thought to earn money to support his family and to make the important decision, so it is right for them to be paid more. Some are even against married women working at all. When wives go out to work, they say, the home and children are given no attention to. (78) If women are encouraged by equal pay to take full-time jobs, they will be unable to do the things they are best at doing: making a nice home and bringing up children . Women who disagree say they want to escape from the limited place which society wishes them to fill and to have freedom to choose between work and home life, or a mixture of the two. Women have the right not only to equal pay but also to equal chances.

单选题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.
