单选题 To what extent are the unemployed failing in their duty to society to work, and how far has the State an obligation to ensure that they have work to do? It is by now increasingly recognized that workers may be thrown out of work by industrial forces beyond their control, and that the unemployed are in some sense paying the price of the economic progress of the community. But concern with unemployment and the unemployed changes sharply. The issues of duty and responsibility were re-opened and made active by the unemployment scare of 1971--1972. Rising unemployment and increased sums paid out in benefits to the workless had reawakened controversies which had been inactive during most of the period of fuller employment since the war ended the Depression. It looked as though in future there would again be too little work to go round, so there were arguments about how to produce more work, how the available work should be shared out, and who was responsible for unemployment and the unemployed. In 1972 there were critics who said that the State's action in allowing unemployment to rise was a barrier of faith, a breaking of the social contract between society and the worker. Yet the main contribution by employers to unemployment--such as laying off workers in order to introduce technological changes and maximize profit-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 of 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 values as members of society became suspect. Of all the myths of the Welfare State, stories of the workshy and stealing have been the least well founded on evidence, yet they have proved the most persistent. 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 subsidized 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?

单选题In the United States, it is not customary to telephone someone very early in the morning. If you telephone him early in the day, while he is shaving or having breakfast, the time of the call shows that the matter is very important and requires immediate attention. The same meaning is attached to telephone calls made after 11:00 p.m.. If someone receives a call during sleeping hours, he assumes it's a matter of life and death. The time chosen for the call communicates its importance. In social life, time plays a very important part. In the U.S.A., guests tend to feel they are not highly regarded if the invitation to a dinner party is extended only three or four days before the party date. But it is not true in all countries. In other areas of the world it may be considered foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten. The meaning of time differs in different parts of the world. Thus, misunderstandings arise between people from cultures that treat time differently; promptness is valued highly in American life, for example. If people are not prompt, they may be regarded as impolite or not fully responsible. In the U.S. no one would think of keeping a business friend waiting for an hour; it would be too impolite. A person who is 5 minutes late is expected to make a short apology. If he is less than 5 minutes late, he will say a few words of explanation, though perhaps he will not complete the sentence.
