In our study we asked people if they had had Covid-19 themselves. Those people     1       responded yes were 3.9 times more likely to be highly resilient. That is to say, the more exposed you were, the    2    (high) your resilience levels. This strongly suggests that we discover our resilience only when we    3     (force) to meet unavoidable suffering full in the face. The real is almost always less scary than the imagined, and the reality of the disease helps you with knowing       4       you’re capable of.

Some high school students have built purifiers to help fight against disease. They put the purifiers together with materials like fans, and had many trials to test their effectiveness in filtering out viral particles. The goal was to make classrooms safer and the students     1     (accomplish) their mission—the filters were tested 90% efficient. “I don’t like wearing masks—they get     2     (annoy) when they’re on long enough,” said one of the students. “So, yes, I like the purifiers, which make me feel     3     (protect), being around everyone but not having to worry about getting sick.”

8 . Now, an increasing number of cities are suspending recycling services, partly out of fear that workers might contact the coronavirus from one another while sorting through used water bottles, food containers and boxes. One solution: Let robots do the job.

Since the coronavirus took hold in the United States last month, AMP Robotics has seen a “significant” increase in orders for its robots that use artificial intelligence to sort through recycled material, and weed out trash. Some facilities that were looking at getting one or two robots are now saying, “We need quite a bit more.” The Colorado company’s chief executive, Matanya Horowitz said, “It’s all moving quite fast.”

Before the pandemic, automation had been gradually replacing human work in a range of jobs, from call centers to warehouses and grocery stores, as companies looked to cut labor costs and improve profit.

But labor and robotics experts say social-distancing directives, which are likely to continue in some form after the crisis become less strong, could cause more industries to accelerate their use of automation. And long-lasting worries about job losses or a broad unease about having machines control vital aspects of daily life could disappear as society sees the benefits of restructuring workplaces in ways that minimize close human contact.

Recycling is one industry that may be altered permanently by the pandemic. Some workers, who earn as little as $10 an hour, have been concerned about coming to work during the crisis and some cities have been competing to find enough protective gear (防护装备) for all of their employees. Federal health officials have assured them that the risks of transmission from household refuse is low. But workers in recycling facilities often work side by side sorting material, making social distancing difficult.

At AMP Robotics, executives like Mr. Horowitz say their robots will enable recycling facilities to space out their employees, who stand at conveyor belts weeding through the used plastic and paper.

9 . How to go abroad and minimize your COVID-19 risk?

If you are desperate to go abroad, then what measures should you take?

“Vaccination (接种疫苗) is of great importance.    1    , I would take the view that you’re going to be pretty safe as long as you observe the usual, sensible rules,” says Anthony Costello at University College London.

The US Centers for Disease Control and Prevention (CDC) agrees.    2    . Travelers are advised to stay at least 1.8 meters away from the people they aren’t traveling with, wash their hands often and monitor their health for signs of illness, too.

You should also take “low risk” with a pinch of salt (有所保留).    3    . That means you have to quarantine (隔离).at home or in the place you are staying for 10 days when you arrive in England. Meanwhile, Portugal remains in the CDC’s “avoid all travel” category.

    4     The US mainly looks at the number of new cases in the past 28 days. Decisions for England are based on broader risk assessments from the Joint Biosecurity Centre, including vaccination rates and circulating variants.

“It is hard to tell which method is right, and it isn’t unusual for two countries to look at the same data and come to opposite conclusions,” says Jeffrey Lazarus at the Barcelona Institute for Global Health in Spain, “Germany closed the border to the UK in the same week when Spain opened it.    5    .”

10 . Chinese people spent more time on leisure activities in 2021 compared with the period before the novel coronavirus hit, according to a recent report by the China Tourism Academy. The academy said that urban residents’ leisure time was closely related to their work. They spent more time on leisure activities on weekends in 2021, about 4. 4hours a day, compared with an average of 3.82 hours a day on workdays. It said that urban residents’ leisure time increased both at weekends and during holidays in 2021 when compared with 2019. Daily weekend leisure time increased by 0.91 of an hour and that during holidays by 0.64 of an hour. The time that people in rural areas spent enjoying leisure activities rose nearly 39 percent compared with 2019, increasing to 4.36 hours a day from 3.14 hours before the COVID-19 pandemic struck.

Shopping at physical stores remained the most popular leisure activity for both urban residents and people in the countryside, followed by activities like facial treatments, hairdressing and manicures(修指甲). “Shopping is my favorite way to give vent to my negative emotions and pressure, also for leisure,” said Li Lingli, a 28-year-old financial analyst in Beijing. She said she had quite a heavy workload on workdays and also on weekends, meaning she didn't have much time to enjoy other leisure activities, especially outdoor ones like camping or hiking.

The report said it will be difficult to increase people’s leisure time in the future due to the large amount of time they spend working and looking after children.

A recent survey by the academy shows that 50 percent of urban residents worked over eight hours a day and 15 percent worked over 10 hours a day. “Heavy workload is truly a big problem,” Li said. “For me, as long as I don’t message or email back my clients, it’s my leisure time. I sometimes go to museums or exhibitions over holidays. It’s also a good form of leisure to appreciate beautiful art pieces.”

Dai Bin, chairman of the academy, said at an online conference that with more rural residents spending time on leisure activities thanks to the nation's rural vitalization(振兴)policy, the tourism market and travel companies will embrace new growth in the future.
