阅读短文。完成27～31题。金属历来都是通过采矿、冶金制取的，可是80年代初期，科学家发现在聚乙炔中加入强氧化剂或还原剂后，它的导电性能大大提高。因为这种塑料具有金属的一般特性，所以人们称它为“人造金属”。近年来，它的发展极为神速，人们又先后研制成功了聚苯乙炔、聚苯硫醚和聚双炔类等。这种人造金属不仅具有金属光泽，还能导电传热，其用途十分引人瞩目。“人造金属”最奇特的功能是它的导电性。与普通塑料不同的是，“人造金属”塑料具有一种独特的线型结构，许多同样的分子能奇妙地结合起来，并带有较多的“自由”电子，这就使原来的塑料改变了物理性能，能够导电。它的导电率比铜、银还要高。普通金属的导电性，随着温度的降低而增大，在接近绝对零度时成为超导，但这种低温度很难得到。而人造金属却相反，随着温度升高，外围“自由”电子释放越来越多，因此导电性增大，在常温下呈现出超导电性能。实现超导，由低温变成常温，这是人造金属创造的一大奇迹，是科学家梦寐以求的目标，用超导体制造的发电机，它的效率可以从30%提高到98%，超导电线将使远距离无损耗输电的设想成为可能，使火车悬浮在轨道上高速运行，也将使有控热核聚变反应成为现实，最终解决能源问题。人造金属的另一突出贡献是，用它制成的新型电池代替笨重、硕大的铅蓄电池，可以使人们长期用蓄电池作为汽车动力有了（）①的可能。人造金属电池可提供相当于常规电池10倍的电力，不需要维修，充电次数可达1000次以上，使用寿命比铅蓄电池长4～5倍，而且不会污染环境。人造金属在外压和光的作用下，能产生电磁效应，把它装在扩音器上，能将声音放大；把它放在红外摄像机上，在红外热能作用下，也能产生工作电流进行录像。此外，人造金属弹性大、易加工、重量轻、耐磨蚀性能好、强度高、成本低。 下列对“人造金属”导电性判断正确的一项是（）。
By 1830 the former Spanish and Portuguese colonies had become independent nations. The roughly 20 million (1) of these nations loved (2) to the future. Born in the crisis of the old regime and Iberian Colonialism, many of the leaders of independence (3) the ideals of representative government, careers (4) to talent, freedom of commerce and trade, the (5) to private property, and a belief in the individual as the basis of society. (6) there was a belief that the new nations should be sovereign and independent states, large enough to be economically viable and integrated by a (7) set of laws.On the issue of (8) of religion and the position of the church, (9) , there was less agreement (10) the leadership Roman Catholicism had been the state religion and the only one (11) by the Spanish crown.

Read the following text. Choose the best word (s) for each numbered blank and mark A, B, C or D on ANSWER SHEET 1.5（）
男，18岁，右大腿有一肿块，前来某医院就诊。甲医师接诊，经拍片检查，疑为骨瘤，但病灶不明显，未确诊，亦未将病情告知患者。半年后，肿块明显增大，再到该院就诊。乙医师接诊，确诊为恶性骨瘤，需截肢。乙医师在与患者家属谈话时，透露半年前甲医师接诊的实情。患者家属听后认为，这次遭受截肢之苦是甲医师的误诊造成。甲、乙医师之间的关系也因此而变坏。 从医际关系角度，对乙医师“透露实情”的做法进行评价，下面的说法正确的是( )。
