Unit 2 Healthy eatingⅠ.阅读理解A(2020·东北三省四市高考模拟) Until last year，Borris would never turn down a pork steak.By the time his owner，Annemarie Formoy，entered him in the PDSA Pet Fit Club petition，he was 28kg—almost double his remended weight.Thanks to a tailored six­month diet and exercise，he is now 7kg lighter.Borris，at his heaviest，was not alone.The worldwide rate of pet obesity(肥胖症) lies between 22% and 44%.The reasons are fairly predictable.Owners of overweight dogs feed them more snacks and table leftovers，are more likely to have their pets present as they prepare their own meals and are less likely to walk them daily.Owners of obese cats tend to use food as a reward and play with them less.But obesity also seems to be occurring even in some wild animals that aren't being overfed or under­exercised.If these findings are true，something else must be driving obesity and uncovering those could help solve our own problems with the condition.“Labradors are consistently the headline act when it es to overweight dogs，”says Eleanor Raffan，a veterinarian and geneticist.She and fellow researchers discovered that a genetic mutation(基因变异) present in around a quarter of Labradors was associated with obesity.For each copy of the mutation—which occurred in a gene called POMC—a dog was about 2kg heavier.Most of the animals the researchers studied had one copy of the mutation，but fewer had two.“These are dogs always in the kitchen when owners are preparing food，sticking around scouring_a_titbit even if there's not much chance of getting food，or eating disgusting stuff on walks，” Raffan says.“But they're not doing that because it's fun.They're doing it because they're hungry.”That's because POMC mutations disturb the brain's function of controlling food intake and energy consumption.As a result，the behaviour of these Labradors beesvery food­motivated.语篇解读全球宠物肥胖率在22%到44%之间，弄清楚宠物肥胖的原因对人类应对肥胖问题也很有启发。
