minute cease his fanatic pounding at the other bench. He gave him a look, but
Sobel’s bald head was bent over the last as he worked, and he didn’t notice. The
shoemaker shrugged and continued to peer through the partly frosted window at,
the near-sighted haze of falling February snow. Neither the shifting white blur
outside, nor the sudden deep remembrance of the snowy Polish village where he
had wasted his youth could turn his thoughts from Max, the college boy (a
constant visitor in the mind since early that morning when Feld saw him trudging
through the snowdrifts on his way to school), whom he so much respected because
of the sacrifices he had made throughout the years in winter or direst heat— A. Feld may not have a happy childhood. B. Feld cherished his childhood memories. C. Feld thought highly of man of perseverance. D. Feld lived an affluent but empty life.

．当物体远离地球时，这些光的频率会移向光谱上的红色端(低频)，简称“红移”，
反之，则称“蓝移”。
原子释放出的这种独特的光也被组成原子的基本粒子尤其是电子的质量所影响。
如果某一原子的质量增加，其释放的光子的能量也会变得更高，因此，
释放和吸收频率将会蓝移。相反，如果粒子变得越来越轻，频率将会红移。
天文观察发现，大多数星系都有红移现象，而且，星系距离地球越远，红移越大，
据此，许多科学家认为宇宙一定在不断膨胀。
以下哪项如果为真，最能反驳上述科学家的观点?
A.在遥远的宇宙中．也发现了个别蓝移的天体 B.地球并非处于宇宙的中心区域 C.人们所能观察的星体可能不足真实宇宙的百分之一 D.从宇宙中其他天体的视角看，红移也是占绝对优势的现象 [判断题]《铁路旅客运输管理规则》规定,饮食供应工作要认真贯彻执行《食品安全法》,加强食品采购、保管、加工、销售等各环节的管理,严防食物中毒。
