第1题
In 1972 there were critics who said that the State's action in allowing unemployment to rise was a faithless act, a breaking of the social contract between society and the worker. Yet in the main any contribution by employers to unemployment such as laying off workers in order to introduce technological changes and maximize profits tended to be ignored. And it was the unemployed who were accused of failing to honor the social contract, by not fulfilling their duty to society to work. In spite of general concern at the scale to the unemployment statistics, when the unemployed were considered as individuals, they tended to attract scorn and threats of punishment. Their capacities and motivation as workers and their value as members of society became suspect. The unemployed were accused of being responsible for their own workless condition, and doubts were expressed about the State' s obligation either to provide them with the security of work or to support them through Social Security.
Underlying the arguments about unemployment and the unemployed is a basic disagreement about the nature and meaning of work in society. To what extent can or should work be regarded as a service, not only performed by the worker for society but also made secure for the worker by the State, and supported if necessary？ And apart from cash are there social pressures and satisfactions which cause individuals to seek and keep work, so that the workless need work rather than just cash？
What the author proposes to examine is ______.
A．how far the unemployed are to blame for their failure in working and how far it is the State' s fault
B．to what extent the State should insist on the unemployed working if they fail to do so
C．whether being at work is a social duty which the State should ensure everybody carries out
D．whether work should be obligatory, and if so, whether the State or the individual is responsible for the enforced obligation

听力原文：W: Howard, what are you working on now？
M: I have just finished a piece on the background music.
W: Background music？ Oh, like the music they're playing here now.
M: Yes. You can hear it everywhere — in restaurants, airports, supermarkets, department stores and so on. It's supposed to influence your attitudes, put you in the right mood.
W: I am not sure I like that idea.
M: Well, it seems to work. Companies pay millions of dollars every year for background music. It's supposed to give you a better feeling about yourself and the people around you. Factories use it a lot. It makes the workers happy, and they work better that way. In one factory, music increased production 4.5 percent.
W: I should think they'd get tired of hearing music all day.
M: They don't, though. One fellow in San Francisco told me, "If the music stops, somebody always runs to the telephone to complain."
W: Now that I think about it, I can't remember when there wasn't background music in restaurants and stores.
M: That shows how young you are. Actually, it all started during World War Ⅱ when some factories had their own orchestras to keep workers happy and calm. Now different kinds of music are playing at different times during the day. They play faster music at ten in the morning than at eight, for instance, because workers tend to be slower then.
W: What about restaurants？ Do they play the same music for dinner and lunch？
M: I don't know about that, but I do know that hamburger places play fast music. When they started playing faster music, they found that a customer spent only seventeen minutes eating. The time was twenty-minutes before that.
