材料分析: 2019 年 12 月 , 武汉发现的冠状病毒是新发现的在人类中传播的病毒株系, 被 WHO 命名为 2019 新型冠状病毒(2019-nCoV)。 冠状病毒是一个大型病毒家族,已知可引起感冒以及中东呼吸综合征(MERS) 和严重急性呼吸综合征(SARS) 等较严重疾病。 新型冠状病毒是以前从未在人体中发现的冠状病毒新毒株。 2019 年 12 月 以来, 湖北省武汉市持续开展流感及相关疾病监测, 发现多起病毒性肺炎病例, 均诊断为病毒性肺炎/肺部感染。人感染了冠状病毒后常见体征有呼吸道症状、 发热、 咳嗽、 气促和呼吸困难等。 在较严重病例中, 感染可导致肺炎、 严重急性呼吸综合征、 肾衰竭, 甚至死亡。 目前对于新型冠状病毒所致疾病没有特异治疗方法。 但许多症状是可以处理的, 因此需根据患者临床情况进行治疗。 此外, 对感染者的辅助护理可能非常有效。 新型冠状病毒感染肺炎的传播途径有三种, 直接传播、 气溶胶传播、 接触传播。 直接传播: 患者喷嚏、 咳嗽、 说话的飞沫、 呼出气体近距离接触直接吸入, 可以导致感染。 气溶胶传播: 飞沫混合在空气中, 形成气溶胶, 吸入后导致感染。 接触传播: 飞沫沉积在物品表面, 接触污染手后,在接触口腔、 鼻腔、 眼睛等粘膜, 导致感染。

阅读理解

    In every British town, large and small, you will find shops that sell second-hand goods. Sometimes such shops deal mostly in furniture, sometimes in books, sometimes in ornaments(装饰) and household goods, sometimes even in clothes.

    The furniture may often be “antique”, and it may well have changed hands many times. It may also be very valuable, although the most valuable piece will usually go to the London salerooms, where one piece might well be sold for hundreds of thousands of pounds. As you look around these shops and see the polished wood of chests and tables, you cannot help thinking of those long-dead hands which polished that wood, of those now-closed eyes which once looked at these pieces with love.

    The books, too, may be antique and very precious; some may be rare first printings. Often when someone dies or has to move house, his books may all be sold, so that sometimes you may find whole libraries in one shop. One the border between England and Wales, there is a town which has become a huge bookshop as well. Even the cinema and castle have been taken over, and now books have replaced sheep as the town's main trade.

    There are also much more humble shops, sometimes simply called “junk shops”, where you can buy small household pieces very cheaply. Sometimes the profits(利润)from these shops go to charity(慈善事业). Even these pieces, though, can make you feel sad; you think of those people who once treasured them, but who have moved on to another country or to death.

    Although the British do not worship(崇拜)their ancestors, they do treasure the past and the things of the past. This is true of houses as well. These days no one knocks them down; they are rebuilt until they are often better than new. In Britain, people do not buy something just because it is new. Old things are treasured for their proven worth; new things have to prove themselves before they are accepted.

  1. (1) Books found in second-hand book shops may          .
    A . be copies of the earliest printings B . be on sale for the first time C . never be worth very much D . never be rare
  2. (2) What is the small town on the border between England and Wales famous for?
    A . Its sheep. B . Its bookshops. C . Its cinema. D . Its castle.
  3. (3) Second-hand goods sometimes fill you with sadness because          .
    A . they are too expensive for average buyers B . they remind you of the original owners C . they are now forgotten D . they are sold for charity
  4. (4) The average British person          .
    A . does not respect old things because they are not fashionable B . likes to build new houses simply because it is fashionable to do so C . likes to buy new things because they are fashionable. D . does not like to buy things simply because they are fashionable
  5. (5) What does the underlined word “them” (Paragraph 4) refer to?
    A . junk shops B . profits from shops C . old things D . old houses
“天苍苍,野茫茫,风吹草低见牛羊”、“ 大漠孤烟直”描述的是(   )
