题型:单项选择题

问题:

一种机场安全扫描器被用来探测行李中的爆炸性物质,每当通过扫描器的行李中包含有爆炸性物质时,扫描器就会提醒它的操作者。当100件不含有爆炸性物质的行李通过扫描器时,扫描器会错误地提醒它的操作者一次。因此,在100次有爆炸性物质的警报中,有99次实际上都存在有爆炸性物质。
上面论述中的推理是错误的,因为该论述:

A.忽视了当一行李确实含有爆炸性物质时,扫描器有不发出警告信号的可能性。

B.基于那些可能有偏见的样品,做了一个关于可靠性的结论。

C.忽视了一旦扫描器给它的操作员发出警告,他或她有人为错误的可能性。

D.在陈述说明百分比时,用一组代替另一个不同的组。

One of the most disturbing statistics I’ve read for a long time was published this week. The Work Foundation claims that job satisfaction in this country has fallen alarmingly. Women’s satisfaction level has fallen from 51 percent in 1992 to 29 percent today; men’s has fallen from 35 percent to 20. The reason — the long-hours culture and job insecurity.
For my father’s generation, work was something that had to be endured so that real life could be maintained. But my generation has been gulled into thinking that work is real life, Most work is not satisfying. Most work stinks. Most work, however well paid, is meaningless and dull. But somehow we’ve been convinced that work provides self-fulfillment.
Before Mrs Thatcher, we had a famous British attitude to work — the less we did the better. Thatcher introduced the idea that, in a world where identity was so fragile, you could become real through work, through long hours and assiduous consumption, in the small amount of time you had been left after clocking off. Now Blair carries on the crusade, I’ve got one of the best jobs in the world — sitting in an office by myself all day trying to make up something that someone somewhere will be interested in. But I’d rather be stretched out in front of the TV, or in bed, or playing tennis, or doing just about anything else.
Much of feminist thought has been about getting what men have traditionally had without examining the underlying assumption of whether it was worth having. Feminism never ended up with a life built around creative leisure, instead, women of talent and drive threw themselves into the labour pool, believing that work and its attendant income and power would affect the change of life and consciousness that would liberate them.
Can anything be done Only if we’re willing to change the way we’ve been tricked into thinking. Most people now measure their lives primarily in units of currency — money saved and spent. I have a friend who’ll travel halfway across London for a shoe sale, without factoring in how much of her precious time has been spent travelling. The most important truth I know is that all we ever own is the time we were given on this earth. We need to seize it back. Now the future has arrived, and we have the means to do it — we just don’t have the imagination.

The sentence "Now Blair carries on the crusade…" (para.3) could be best illustrated by which of the following statements

A.(A) Blair continues to promote the idea of achieving self-fulfillment through work.

B.(B) Blair opposes his people to be workaholic and has launched such a campaign.

C.(C) Blair sets a perfect example as a hard-working person for his people in the UK.

D.(D) Blair is most unwilling to have his people labouring as slaves.
