下列说法错误的是（ ）。
- A.热水管往往比冷水管先被冻裂
- B.高尔夫球上的微凹坑使作用于球上的空气阻力减小
- C.自燃是由于材料内部的氧化使得材料的热量增加而引起的
- D.材料能够燃烧是由于可燃材料富含一种叫“燃素”的物质
正确答案及解析
正确答案
解析
热水管，在高温条件下的稳定性和力学性能更好，但是在低温的条件下则会有脆性，易损坏几率较高。冷水管，在低温条件下的韧性非常好，在高温条件下使用的话，则易变形。A选项正确。高尔夫球上的微凹坑使作用于高尔夫球上的空气阻力（当物体穿过气体时使物体失去能量的力）减少到最小，使球运动的距离超过光滑的球运动的距离。当空气流过有微凹坑的高尔夫球表面时，会较长时间地附着在球体上，从而减少消耗球体能量的涡流或气流的影响。B选项正确。
可燃物质和空气接触都会发生缓慢的氧化过程，如果温度升高或其他条件改变，氧化过程就会加快，析出的热量增多，不能全部散发掉就积累起来，使温度逐步升高。当到达这种物质燃烧的最低温度也就是该物质的着火点时，就会自行燃烧起来，这就是自燃。C选项正确。燃素学说是很久很久以前的化学家们对燃烧的解释,他们认为火是由无数细小而活泼的微粒构成的物质实体。这种观念是错误的。燃烧是可燃物与氧气或空气进行的快速放热和发光的氧化反应，并以火焰的形式出现。D选项错误。

Two years ago,Rupert Murdoch’s daughter,Elisabeth,spoke of the“unsettling dearth of integrity across so many of our institutions”.Integrity had collapsed,she argued,because of a collective acceptance that the only"sorting mechanism"in society should be profit and the market.But"it's us,human beings,we the people who create the society we want,not profit".
Driving her point home,she continued:“It’s increasingly apparent that the absence of purpose,of a moral language within government,media or business could become one of the most dangerous goals for capitalism and freedom.”This same absence of moral purpose was wounding companies such as News International,she thought,making it more likely that it would lose its way as it had with widespread illegal telephone hacking.
As the hacking trial concludes-finding guilty one ex-editor of the News of the World,Andy Coulson,for conspiring to hack phones,and finding his predecessor,Rebekah Brooks,innocent of the same charge-the wider issue of dearth of integrity still stands.Journalists are known to have hacked the phones of up to 5,500 people.This is hacking on an industrial scale,as was acknowledged by Glenn Mulcaire,the man hired by the News of the World in 2001 to be the point person for phone hacking.Others await trial.This saga still unfolds.
In many respects,the dearth of moral purpose frames not only the fact of such widespread phone hacking but the terms on which the trial took place.One of the astonishing revelations was how little Rebekah Brooks knew of what went on in her newsroom,how little she thought to ask and the fact that she never inquired how the stories arrived.The core of her successful defense was that she knew nothing.
In today’s world,it has become normal that well-paid executives should not be accountable for what happens in the organizations that they run.Perhaps we should not be so surprised.For a generation,the collective doctrine has been that the sorting mechanism of society should be profit.The words that have mattered are efficiency,flexibility,shareholder value,business-friendly,wealth generation,sales,impact and,in newspapers,circulation.Words degraded to the margin have been justice,fairness,tolerance,proportionality and accountability.
The purpose of editing the News of the World was not to promote reader understanding,to be fair in what was written or to betray any common humanity.It was to ruin lives in the quest for circulation and impact.Ms.Brooks may or may not have had suspicions about how her journalists got their stories,but she asked no questions,gave no instructions-nor received traceable,recorded answers.
Which of the following is suggested in the last paragraph?（ ）
-
- A.The quality of writings is of primary importance
- B.mmon humanity is central to news reporting
- C.Moral awareness matters in editing a newspaper
