问题 选择题

下图是由芝加哥大学《原子科学家公报》杂志设立的虚构的“世界末日钟”,指针距离零点的远近象征着世界距离毁灭的远近,其变化通常与核威胁相关。杂志社根据世界局势将分针拨前或拨后,以此提醒世人正视核威胁。下列说法正确的是

③苏联解体、东欧剧变会使分针拨后  ④新科技可能给人类带来更大的危害

A.①②③

B.①②④

C.②③④

D.①③④

答案

答案:D

题目分析:本题主要考查学生阅读材料,获取信息及知识的迁移能力,依据已学知识可知核武器以相对论为理论依据,利用聚变或者裂变产生的质量亏损转化为巨大能量,①符合史实;美苏核恐怖,使世界处于核战争的威胁之下,给世界带来不和平的因素,②说法有误;苏联解体、东欧剧变标志着两级格局的解体,世界朝着多极化方向发展,利于世界的和平,因此会使分针拨后,③符合史实;题干中核武器是新科技的一种体现,先进的科技既给人类造福,也给人类带来了灾难,科技是一把双刃剑,④的表述符合史实,故选D。
