5、and dynamic zeroing of new infections” can deal with all variants.The strategy has also enabled China to win a window of opportunity in terms of building up scientific support to fight the virus, he said. Ongoing work includes increasing reserves of vaccines（疫苗）and drugs to support the global battle
6、 against the pandemic, and boosting inventories（存货）of Chinas public health and medical resources.According to Wu Zunyou, Chinas overall epidemic situation remains stable and under control against a backdrop of surging infections globally. “This remarkable outcome is largely due to the central approa

China, where so far only Hong Kong has reported cases, is calmly and confidently responding to possible challenges with vaccine (疫苗) study and the experience got from China
13、s zero-COVID policy.Chinese observers said that China will benefit from its COVID-19 policy of preventing cases from home and abroad which continues to show its unique advantages facing Omicron. In comparison, observers reminded that Western countries are likely to be affected by Omicron if the vari
14、ant is highly infectious (感染的), with their unscientific epidemic (流行病) control measures and overconfidence in vaccines, which has led to the rapid spread of the new variant, an expert told Global Times on Tuesday.But to some Western media, Chinas policy means isolation (隔离). CNN said in a report on
15、Monday that as much of the world started to learn to live with COVID-19, Chinalooked increasingly isolated by comparison”.Chinese observers said that the Wests choice of dealing with COVID-19 is a helpless action as they cannot possibly clear their domestic cases with large numbers of locally transm

20、c seriously.（三）The Omicron Covid variant has been found to multiply about 70 times quicker than the original and Delta versions of coronavirus in tissue samples taken from the bronchus(支气管), the main tubes from the windpipe to the lungs, in laboratory experiments that could help explain its rapid tr
21、ansmission.The study, by a team from the University of Hong Kong, also found that the new variant grew 10 times slower in lung tissue, which the authors said could be an indicator of lower disease severity.Michael Chan, who led the work, said the result needed to be interpreted with caution because
22、severe disease is determined not only by how quickly the virus replicates(复制) but also by a persons immune response. “It is also noted that by infecting many more people, a very infectious virus may cause more severe disease and death even though the virus itself may be less pathogenic(致病的),” he sai
23、d. “Therefore, taken together with our recent studies showing that the Omicron variant can partially escape immunity from vaccines and past infection, the overall threat from the Omicron variant is likely to be very significant.”Jeremy Kamil, an associate professor of microbiology and immunology at
24、Louisiana State University Health Shreveport, pointed out that Delta, which turned out to be more pathogenic, showed a similar pattern of replicating more slowly in the lungs. “These authors found Omicron replicates fantastically well-even far better than either Delta or the original virus-in bronch
25、ial tissue,” Kamil said. “This could in some ways contribute to an advantage in transmission between people.”Kamil added, “Of course, a huge component of Omicrons transmissibility in real life is going to be its potential to escape neutralising antibodies that protect against infection in the first
26、place. Its very likely spreading well even between vaccinated people, especially those who havent recently gotten a booster shot.”The findings, together with other recent work showing Omicron infects cells more readily, add to an emerging picture that the variant may be intrinsically more transmissi

But many countries rushed to act, reflecting anxiety about anything that could prolong the

Scientists in several places from Hong Kong to Europe to North America have confirmed its presence. The Netherlands re

34、riants. Collins, along with several experts, said that the news should make everyone redouble their efforts to use the tools the world already has, including vaccinations, booster shots and measures such as mask-wearing. “I know, America, youre really tired about hearing those things, but the virus
35、is not tired of us,” Collins said.As more omicron cases have been found in more countries such as Dutch, Canada, Australia, many countries are introducing travel bans or closing borders, though they go against the advice of the WHO.

41、答案和解析1.A2.B3.C4.C【解析】本文为一篇说明文。文章主要讲述了中国现有的新冠遏制战略（以坚定快速的方式中断新冠的传播阻挡新的爆发），能够有效地对抗新冠变异的Omicron病毒，这种策略还会加大力度来预防冬季疫情的爆发。1.细节理解题。根据文章第一段“Chinas existing COVID-19 containment strategy, characterized by firm and rapid response to cut its transmission and block new outbreaks, should be sufficient for dealing
42、 with the new Omicron variant（变种）of the novel coronavirus, health experts and officials said recently.（中国现有的新冠遏制战略（以坚定快速的方式中断新冠的传播阻挡新的爆发），能够有效地对抗新冠变异的Omicron病毒）”可知，此篇文章主要讲中国新冠战略可以对抗Omicron病毒，故选A。2.细节理解题。根据文章第一段“Chinas existing COVID-19 containment strategy, characterized by firm and rapid response t
43、o cut its transmission and block new outbreaks（中国现有的新冠遏制战略，以坚定快速的方式中断新冠的传播阻挡新的爆发）”可知，中国现在抗疫的战略是坚定有效的，故选B。3.细节理解题。根据文章第六段“The strategy has also enabled China to win a window of opportunity in terms of building up scientific support to fight the virus, he said（他说道，就建立对抗病毒的科学支撑来讲，这个战略能让中国赢得机会）”可知，现在的战略
44、能让中国在科学准备方面取得机会，故选C。4.推理判断题。根据文章第二段“the countrys dynamic zero-case policy should continue to be enforced this winter and spring（国家的动态零病例政策在今年冬天和春天应继续加大力度执行）”可知，动态零病例政策还会持续一段时间，故选C。5.D6.C7.A8.B【解析】本文是一篇说明文。文章主要介绍了尽管是欧米克隆的变种，新冠病毒在中国仍然处于控制之下。5.推理判断题。根据第一段“China, where so far only Hong Kong has reported
45、 cases, is calmly and confidently responding to possible challenges with vaccine study and the experience got from Chinas zero-COVID policy.（迄今为止，只有香港报告了新冠肺炎病例，中国在疫苗研究方面沉着、自信地应对可能面临的挑战，并从中国的“新冠病毒清零”政策中获得了经验。）”以及第三段“But to some Western media, Chinas policy means isolation（隔离）. CNN said in a report on
46、 Monday that as much of the world started to learn to live with COVID-19, China u looked increasingly isolated by comparison”.（但对一些西方媒体来说，中国的政策意味着隔离。CNN在周一的一篇报道中表示，随着世界上许多国家开始学习与COVID-19共存，相比之下，中国看起来越来越孤立。”）”可推断，中国的“新冠病毒清零”政策指的是一种严肃的为清除病例的控制方法。故选D。6.词义猜测题。根据前一段的尾句“In some countries, even the leaders
47、 do not follow their own rules.（在一些国家，甚至领导人也不遵守自己的规则。）”和划线词前半句“Biden on Monday call on Americans to wear masks,(周一，拜登呼吁美国人戴上口罩，)”和转折词but及后文可知，拜登呼吁美国人戴上口罩，但他因违反自己的规定而受到抨击。所以flouting为“违反”之意。故选C。7.推理判断题。根据第二段末尾“on Tuesday（在周二）”以及最后一段“on Monday（在周一）”可推断，本文没有按照时间顺序展开文章。故选A。8.主旨大意题。根据第一段“With the world re
48、porting more cases of Omicron variant on Tuesday and more Western countries hurry up to close their doors. China, where so far only Hong Kong has reported cases, is calmly and confidently responding to possible challenges with vaccine study and the experience got from Chinas zero-COVID policy.（随着世界各地周二报告了更多的欧米克隆变种病例，越来越多的西方国家急于关闭国门。迄今为止，只有香港报告了新冠肺炎病例，中国在疫苗研究方面沉着、自信地应对可能面临的挑战，并从中国的“新冠病毒清零”政策中获得了经
