China’s existing COVID-19 containment strategy, characterized by firm and rapid response to cut its transmission and block new outbreaks, should be sufficient for dealing with the new Omicron variant（变种）of the novel coronavirus, health experts and officials said recently.
They added that the country’s dynamic zero-case policy should continue to be enforced this winter and spring, as new modeling shows that dropping it prematurely would risk causing “a huge outbreak”.
Wu Zunyou, a chief epidemiologist, said the new variant appears to be more contagious（传染的）than the Delta variant due to its exceptionally high number of spike mutations.
“But no matter how the virus mutates, regular public health measures, such as wearing masks, maintaining social distancing and washing hands, will be effective against all variants,” Wu said.
Zhang Wenhong, a well-known doctor from Shanghai, said China’s current “rapid response 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 against the pandemic, and boosting inventories（存货）of China’s public health and medical resources.
According to Wu Zunyou, China’s overall epidemic situation remains stable and under control against a backdrop of surging infections globally. “This remarkable outcome is largely due to the central approach of interrupting the spread of the virus, blocking new outbreaks and implementing quarantine（隔离）for incoming travelers,” he said.
“By the most conservative estimates, the strategy had avoided 47.8 million COVID-19 infections and 950, 000 related deaths in China,” he said.
As the outlook for the pandemic remains serious for this winter and spring, Wu said these measures should continue to be enforced.
“Adjustment（调整）of virus control measures should be done extremely carefully and with every detail and procedure being taken into consideration, so as to avoid making mistakes or taking the wrong path,” he said.

With the world reporting more cases of Omicron variant (欧米克隆变种) 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 (疫苗) study and the experience got from China’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 variant 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, China’s policy means isolation (隔离). CNN said in a report on Monday that as much of the world started to learn to live with COVID-19, China"looked increasingly isolated by comparison”.
Chinese observers said that the West’s choice of dealing with COVID-19 is a helpless action as they cannot possibly clear their domestic cases with large numbers of locally transmitted cases, and residents are unwilling to team up with governments. In some countries, even the leaders do not follow their own rules.
Biden on Monday call on Americans to wear masks, but he has come under fire for flouting his own rules. He was pictured without a mask covering his face over the Thanksgiving weekend in a shop that had a sign on the window requiring customers to wear face coverings, the BBC reported.
5．What is the zero-COVID policy?
A．The vaccine can kill all the variants of the epidemic.
B．No one goes out and people will close the doors for isolation.
C．It is a useful measure to reduce the local infection.
D．It is a serious control method to clear the cases.
6．What does the underlined word “flouting” mean?
A．observing
B．hating
C．going against
D．following
7．Which means does the author NOT use to develop the passage?
A．By following the time order.
B．By giving examples.
C．By making comparisons.
D．By quoting.
8．What is the main idea of the report?
A．Western countries are likely to be affected by Omicron.
B．Despite the Omicron variant, it is still under control in China.
C．Western choice is helpless when faced with COVID-19.
D．Biden call on Americans to deal with the epidemic seriously.

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 transmission.
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 severe disease is determined not only by how quickly the virus replicates(复制) but also by a person’s 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 said. “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 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 bronchial tissue,” Kamil said. “This could in some ways contribute to an advantage in transmission between people.”
Kamil added, “Of course, a huge component of Omicron’s transmissibility in real life is going to be its potential to escape neutralising antibodies that protect against infection in the first place. It’s very likely spreading well even between vaccinated people, especially those who haven’t 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 transmissible in addition to escaping existing immunity.
9．What is the kind of the passage?
A．A news report.
B．A science fiction.
C．A health guide.
D．A medicine advertisement.
10．What could Jeremy Kamil agree with?
A．We should take the result seriously.
B．Omicron may cause more severe disease and death.
C．Both Omicron and Delta grew slowly in the lungs.
D．Those who have gotten a booster shot won’t be infected.
11．What can we learn about Omicron?
A．It is a new variant of Delta.
B．Delta is less pathogenic than it.
C．Vaccinated people needn’t worry about it.
D．It may pose a great threat to people’s health.
12．According to the passage, which of the following may cause Omicron’s transmissibility?
A．That many people haven’t been vaccinated.
B．That many people refused to wears masks in public.
C．That Omicron infects lung cells much more quickly.
D．That existing immunity plays a poor part in fighting Omicron.

Cases of the omicron variant of the coronavirus popped up in countries on opposite sides of the world on Sunday and many governments rushed to close their borders even as scientists cautioned that it’s not clear if the new variant is more alarming than other versions of the virus.
The variant was identified days ago by researchers in South Africa, and much is still not known about it, including whether it is more infectious, more likely to cause serious illness or more able to evade the protection of vaccines. But many countries rushed to act, reflecting anxiety about anything that could prolong the pandemic that has killed more than 5 million people.
Israel decided to bar entry to foreigners, and Morocco said it would suspend all incoming flights for two weeks starting Monday. Scientists in several places — from Hong Kong to Europe to North America — have confirmed its presence. The Netherlands reported 13 omicron cases on Sunday, and both Canada and Australia each found two.
Dr. Francis Collins, director of the National Institutes of Health in the United States, meanwhile, emphasized that there is no data yet that suggests the new variant causes more serious illness than previous COVID-19 variants. 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, you’re really tired about hearing those things, but the virus 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. It has warned against any overreaction before the variant is thoroughly studied, noting that travel restrictions may play “a role in slightly reducing the spread of COVID-19 but place a heavy burden on lives and livelihoods.”
Spain announced it won’t admit unvaccinated British visitors starting Dec. 1. David Hui, a respiratory medicine expert in Hong Kong, agreed with that strategy, saying the two people who tested positive for the omicron variant had received the Pfizer vaccine and exhibited very mild symptoms, such as a sore throat.
13．What does the underlined word “evade” in Paragraph 2 probably mean?
A．escape from
B．help with
C．come down with
D．engage in
14．According to Dr. Francis Collins, we know that ________.
A．more and more countries will have to close their borders.
B．omicron has already made Americans tired of the disease.
C．the new variant has caused more serious illness than the previous one.
D．regular public health measures are effective against the variant.
15．What can we learn from the passage?
A．World Health Organization is against omicron-related travel bans.
B．The new variant is thought to have originated in South Africa.
C．The previous vaccine is of little use in fighting against omicron.
D．Spain has its border closed to foreign travelers including British visitors.
16．Which would be the best title for this passage?
A．More countries have begun to introduce travel bans
B．Great damage caused by a new variant called omicron
C．More omicron cases emerge as world rushes to learn more
D．Vaccinations and booster shots recommended to be pushed
