Robots have certain advantages compared to humans：They are efficient，tireless，can be repaired when damaged and they never get sick．This last trait has made them the star during our fight against the COVID-19 pandemic．While hundreds of thousands of medical workers have fallen ill dealing with this highly infectious virus and a lot more are forced to stay at home for fear of getting the disease，this isn't a problem for robots．
   This is why the COVID-19 outbreak is seen as the "tipping point"---noted The Independent Science reporter Anthony Cuthbertson---for robots to start to replace humans in certain jobs．
   In areas like hospitals and healthcare facilities，robots are used to perform high-risk tasks．In China，for example，a hotel in Hangzhou employed a robot named "Little Peanut" to deliver food to people under quarantine（隔離期）．In Spain，robots are about to be used to test people for the coronavirus．Ultraviolet-light-disinfection（紫外線消毒） robots are also being widely used to clean hospital corridors and wards．
   "Hospitals around the world are waking up to autonomous disinfection，" Per Juul Nielsen，CEO of Denmark's UVD Robots，a leading company manufacturing disinfection robots，told Forbes． "We can't build these robots fast enough．"
   In non-medical companies，robots are also replacing human employees since they don't have the problem of social distancing and will never take sick leave．Walmart and Amazon，for example，where robots are already used in sorting，packing and shipping，are planning to increase the number of robots in their facilities．Fast-food chains like McDonald's are not only delivering food with robots in some areas，but also looking to use them as cooks and servers．
   According to futurist Martin Ford，using more robots than human employees can prove to be rewarding for companies---even when the pandemic is over． "People will prefer to go to a place that has fewer workers and more machines because they feel they can lower overall risk，" Ford told the BBC．
   But this sudden surge（激增） in robot demand doesn't mean that they triumph over humans in every aspect．According to Bill Smart，a roboticist at Oregon State University，the human contact between doctors and patients is still important．Doctors comfort the patients and guide them through hard decisions while robots are only doing routine tasks，like cleaning and giving tests，just to free up doctors and nurses．
   It might be true that robots have certain advantages over humans，but they are still secondary to human interaction．

  • 1．Astronauts travelling in space meet forms of radiation that are uncommon on Earth.Some of this radiation has been shown to be harmful to human health.It is linked to cancers and heart problems.Yet a new American study suggests the radiation does not shorten astronauts' lives.
       Researchers studied nearly 60 years of health records and other data about male astronauts from the United States.They then compared this data with information about a group of men who are in good health，richer than most Americans and receive good health care-professional athletes.The study found that neither group has higher rates of dying at a young age.In fact，both groups generally live longer than other Americans.
       Astronauts are usually well educated，earn more money and are in better physical condition than the average American.Some earlier research has linked being an astronaut to a lower risk of early death，the researchers noted.The findings were reported in the publication Occupational & Environmental Medicine.
       Much of the existing research on mortality rates in astronauts has not yet explored the mental and physical demands of this job.There also has not been a lot of research on whether astronauts show what is known as the "healthy worker effect".This effect leads people with employment of any kind to have fewer medical problems than people who are unable to work，said Robert Reynolds.
       Reynolds said， "The challenge has always been to understand if astronauts are as healthy as they would be had they been otherwise comparably employed but had never gone to space at all.To do this，we need to find a group that is comparable on several important factors."

    （1）How did researchers carry out their study？

    A．By doing interviews.
    B．By analysing some factors.
    C．By comparing different data.
    D．By doing experiments in the lab.
    （2）What can we learn from the text？

    A．All radiation is harmful to human health.
    B．Athletes tend to be poorer than most Americans.
    C．Healthy worker effect makes working people healthier.
    D．Research has explored the mental and physical demands of being astronauts.
    （3）What can be inferred from Reynolds' words？

    A．Researchers are determined to face the challenge.
    B．The research is almost impossible to conduct.
    C．Several important factors hold back the research.
    D．Astronauts are as healthy as they would be if they haven't been astronauts.
    （4）What can be a suitable title for the text？

    A．Astronauts-healthy or otherwise
    B．Astronauts are as healthy as athletes
    C．Radiation affects astronauts' health
    D．Astronauts-well-educated and earn more

  • 3．Some caterpillars' warning signals（信號）may have evolved（進化）from walking.
       A team，writing in the journal Nature Communications，reported that the hair-like structures the living things use to make sounds evolved from legs.
       The team studied caterpillars which use these structures to communicate their ownership of leaves.This means the caterpillars are able to"tell"strangers to go away without risking injury in fighting."These are really interesting caterpillars，"said Dr.Jayne Yack from Carleton University in Ottawa，Canada，who led the research."They make signals using hair-like structures which are on their back ends."
       The caterpillars drag these structures across the leaf to make scraping（刺耳的）sounds when strangers enter the area of their leaves."When they make this signal，the strangers leave，"explained Dr.Yack."It's like saying'I'm here，get out of here-I already own this leaf '."
       The scientists looked at other species（物種）within the same group of caterpillars and created their"family tree".They used chemical markers（標記物）to work out the relationship between the animals，showing which in the group were the more ancient species and which species evolved more recently."Those more ancient species actually don't have these sound-producing structures.They have legs that they use to walk towards strangers，"said Dr.Yack.These more ancient species，she explained，walk towards strangers and try to fight against them."They can kill each other in the fighting，"Dr.Yack added.She said that the evolution of the scraping show had allowed the caterpillars to solve their fighting without injury."So our idea is that these signals actually avoid harm to both sides-they solve fighting in a more' friendly' way."
       The study also provides a map of an evolutionary process that many other biologists are researching.

    （1）What can we learn about caterpillars' warning structures from the text？

    A．They have the same use as hair.
    B．They are found in caterpillars' heads.
    C．They are used to fight against strangers.
    D．They may have evolved from caterpillars' legs.
    （2）According to the text，Dr.Yack's team did NOT
    .
    A．draw a family tree of caterpillars
    B．create a map to show how caterpillars evolve
    C．study species within the same group of caterpillars
    D．make clear the relationship between different species of caterpillars
    （3）What does the underlined word"They"in the fifth paragraph refer to？

    A．The ancient species.
    B．The chemical markers.
    C．The sound-producing structures.
    D．The more recently evolved species.
    （4）What is the main idea of the text？

    A．How caterpillars evolved.
    B．How caterpillars warn strangers.
    C．Communication between caterpillars.
    D．Caterpillars' warning signals evolved from walking.
