[填空题]
Do mobile phones cause explosions at petrol stations That question has just been exhaustively answered by Adam Burgess, a researcher at the University of Kent, in England. Oddly, however, Dr Burgess is not a physicist, but a sociologist. For the concern rests not on scientific evidence of any danger, but is instead the result of sociological factors: it is an urban myth, supported and propagated by official sources, but no less a myth for that. Dr Burgess presented his findings this week at the annual conference of the British Sociological Association.
Mobile phones started to become widespread in the late 1980s, when the oil industry was in the middle of a concerted safety drive, Dr Burgess notes. This was, in large part. a response to the Piper Alpha disaster in 1988, when 167 people died in an explosion on an oil platform off the Scottish coast. (41)__________So nobody questioned the precautionary ban on the use of mobile phones at petrol stations. The worry was that a

[单项选择] Family Matters
This month Singapore passed a bill that would give legal teeth to the moral obligation to support one’’s parents. Called the Maintenance of Parents Bill, it received the backing of the Singapore Government.
That does not mean it hasn’’t generated discussion. Several members of the Parliament opposed the measure as un-Asian. Others who acknowledged the problem of the elderly poor believed it a disproportionate response. Still others believe it will subvert relations within the family: cynics dubbed it the "Sue Your Son" law.
Those who say that the bill does not promote filial responsibility, of course, are right. It has nothing to do with filial responsibility. It kicks in where filial responsibility fails. The law cannot legislate filial responsibility any more than it can legislate love. All the law can do is to provide a safety net where this morality provide insufficient. Singapore needs this bill not to replace morality, b

B. public support.
C. government assurance.

Opinion polls are now beginning to show a reluctant consensus that, whoever is to blame and whatever happens from now on, high unemployment is probably here to stay. This means we shall have to find ways of sharing the available employment more widely. But we need to go further. We must ask some fundamental questions about the future of work. Should we continue to treat employment as the norm Should we not rather encourage many other ways for self-respecting people to work Should we not create conditions in which many of us can work for ourselves, rather than for an employer Should we not aim to revive the household and the neighbourhood, as well as the factory and the office, as centres of production and work
