（2022·广西·南宁三中模拟预测）Scientists in the Netherlands have trained bees to identify
COVID-19 through their n of smell, according to a press relea from Wageningen University. The rearch was conducted on more than 150 bees in Wageningen University’s bio-veterinary rearch laboratory.
The scientists trained the bees by giving them a treat — a sugar-water solution — every time they were expod to the scent of a mink (貂) infected with COVID-19. Each time the bees were expod to a non-infected sample, they wouldn’t get a reward. Eventually, the bees could identify an infected sample within a few conds — and would then stick out their tongues like clockwork to collect the sugar water.
Bees aren’t the first animals to detect COVID-19 by scent. Rearchers have also trained dogs to distinguish between positive and negative COVID-19 samples from human saliva (唾液) or sweat with fairly high levels of accuracy. A small German study found that dogs could identify positive COVID-19 samples 94% of the time. That’s becau metabolic changes from the coronavirus make an infected person’s bodily fluids smell slightly different from tho of a non-infected person. But rearchers still aren’t sure whether animals are the best bet for sniffing out COVID-19 cas outside the lab.

“No one is saying they can replace a PCR machine, but they could be very promising,” Holger Volk, a neurologist, told Nature. PCR machines are what lab technicians u to process standard COVID-19 swab tests. At the very least, certain animals could be uful for identifying COVID-19 in places or countries in which high-tech laboratory equipment is scarce or inaccessible.
Wageningen scientists are working on a prototype of a machine that could automatically train multiple bees at once. Then bees can u their skills to test for coronavirus aerosols (气溶胶) in the surrounding environment.

（2022·广西北海·高三阶段练习）Dogs are born to sociali with people becau we rai them that way. Two-month-old dogs can already recogni when people are pointing at objects and will stare at our faces when they’re spoken to—both signs that dogs have an innate capacity to interact with us through body language.
“Although individual relationships with people might influence that behaviour, at least 40percent of this ability comes from genetics alone, “says Emily Bray at the University of Arizona. “Over the cour of keeping dogs, there has been a clear lection for the social skills,” she says. “It’s something that’s deep in them and that comes out at a really young age even before they have much experience with humans.”
Bray and her colleagues tested the types of skills in 375 eight-week-old dogs that were chon to become rvice dogs. Bray says, “It was the earliest age when the dogs could carryout such experiments becau they were only just old enough to be motivated by food rewards.”
The rearchers found that pointing at food hidden under a cup helped the dogs to find it nearly 70 percent of the time. The success rate was high from the start, meaning they weren’t learning to follow pointing, but had already known to do so. In a control test, the randomly lected dogs couldn’t find food hidden under one of the two cups at a higher rate, indicating that they weren’t simply smelling it. Much of the variation in different dogs’ abilities to follow finger-pointing is explained by genetics. Using statistical analys bad on the dogs’ parents and other relatives, the rearchers found that genetic factors were responsible for much of the variations.
