Animals do have their own languages just as humans do. Scientists who study the evolution of language say wild chimpanzees(黑猩猩) have a more complex communication system     1     past research has shown. The researchers say the animals use over ten kinds of calls     2    can be combined into hundreds of different orders.

The study team made 4,800 recordings of calls produced by members of three groups of chimpanzees    3    (live) in Ivory Coast’s National Park. It’s one of the last important     4     (area) of old-growth tropical forest in West Africa and home to a variety of plants and animals, Chimpanzees stay the closest to humans. They are    5    (intelligence) and sociable. Chimpanzees make and use tools and can    6     (teach) a small amount of human sign language.

Scientists    7    (know) that chimpanzees use different calls in    8    wild since a long time ago. But the new study helped people    9    (far)understand the animals’ communication. Cedric was the lead writer of the study. He spoke of the chimpanzee calls, “It is not a language but it is among the most complex forms of communication    10    (describe) in a nonhuman world.” It can be seen that the secrets of nature are still waiting for human beings to explore.

Can you get reinfected with the coronavirus? Yes, it’s definitely possible to get COVID-19more than once.

“Even before the virus started to turn into different variants, there were already many     1     (document) cases of people getting reinfected,” Dr OttoYang, a professor in infectious diseases, told TODAY. As more variants emerge, reinfections only become more likely because those variants can     2     (potential) escape the immune protection we already have.

Dr Bernard Camins notes that     3     experts may define as a “mild” infection can still feel subjectively awful-and of course cause     4     (disrupt) in your daily life. “In most cases, the symptoms are less severe, meaning your likelihood of death or severe disease is     5     (low),” he said. But if your symptoms cause you to miss work for a longer period of time or it takes you a few weeks     6     (recover), “that’s still pretty significant” even if it doesn’t send you to hospital.

And there is still a small chance that you may experience severe symptoms or that you will spread the virus to someone with a weakened immune system or other hidden condition that puts them     7     a higher risk. Among 7, 300 patients hospitalized with symptoms like those of COVID-19, those who were unvaccinated (未接种疫苗) but previously     8     (have) the illness were five times more likely to test positive for the infection than those who were vaccinated.

To prevent COVID-19 reinfections, you can use     9     same public health strategies that we know can help prevent an initial coronavirus infection. That     10       (include) getting vaccinated, wearing a mask in public, getting tested when appropriate and focusing on ventilation (通风) .

It is too early to label Omicron variant infections as “big flu”. For individuals, the risk of severe symptoms caused by Omicron may decrease, but the virus spreads quickly, said Liang Wannian, head of the COVID-19 response expert panel under China’s National Health Commission (NHC). “If there is a large absolute number of people     1     (infect), the number of severe cases and deaths in the population as a whole will be high, which can still inflict great harm,” he noted. None of the mainstream health experts in the world say Omicron should be regarded as just another flu virus. It is mainly Western politicians in countries     2     the pandemic is out of control that are doing that.

Liang stressed that the essence of China’s dynamic zero-COVID approach is a swift response and targeted response measures. “    3     an outbreak is detected, we have a range of ways to nip it in the bud,” he said. “The key lies in ensuring its early detection and disposal.” Liang warned     4     any slackness, hesitation, or the mentality of taking chances in the anti-COVID fight,     5     (say) that the virus can spread exponentially if it had not been detected in a timely manner or intervened immediately.

The dynamic zero-COVID approach, the Chinese public health policy that     6     (implement) to fight the coronavirus over the past two years, has proved to be effective in striking a good balance between epidemic prevention and control, economic, and social development, according to Liang. The goal of this approach is     7    (bring) the epidemic under control in the shortest possible time with a minimum cost to society.

“The latest resurgence in China does not mean that     8     country’s COVID-19 response policy and measures are ineffective,” Liang said. The infections have increased exponentially in many countries and regions in a short period of time     9     the Omicron variants raged across the world. “However, China has witnessed a slower increase in the number of infections,     10     is precisely because we have taken a series of effective intervention measures to curb the virus,” he added.
