E　　Have you winterized your horse yet? Even though global warming may have made our cli,ate ,ore mild, many animals are still hibernating(冬眠). It’s too bad that humans can’t hibemate. In fact, as a species, we almost did.
　　Apparently, at times in the past, peasants in Fance liked a semi-state of hunman hibemation. Scwrites Graham Robb, a Brinsh scholar who has studied the sleeping habits of the French peasants. As soon as the weather turned cold, people all over the France shut themselves away and practiced the forgotten art of doing nothing at all for months on end.
　　In line with this, Jeff Warren, a producer at CBC Radio’s The Current, tells us that the way we sleep has changed fundamentally since the incention of artificial(人造的)lighting and the electric bulb.
　　When historians began studying texts of the Middle Ages, they noticed something referred to as “first sleep”.which was not clarified, though, Now scientists are telling us our ancestors most likely slept in separate periods. The business of eight hours’uninterrupted sleep is a modem incention,
　　In the past, without the artificial light of the city bathe in, humans went to sleep when it became dark and then world themselves around midnight, The late night period was known as “The Watch”. It was when people actually kept watch against wild animats,although many of them simply moved around or visited lamily and neighbours.
　　According to some sleep researchers, a short of insomnia（失眠） at midninght is not a disorder. It is normal. Humans can experience another state of consciousness around their sleeping,which occurs in the beief period berore we fall asleep or wake ourselves in the morning, This period can be an extraordinarily creative time for some people. The impressive inventor, Thomas Edison, used this state to hit uponmany of his new ideas.
　　Flaying with your sleep rhythms can be adaunturous,as anxiety may set in. Medical science doesn’t help help much in this case. It offers us medicines for a full night’s continuous sleep, which sounds natural; however, according to Warren’s theory, it is really the opposite of what we need.The example of the French peasanls shows the fact that__________. A．people might become lazy as a result of too much sleep
B．there were signs of hibernation in hunan sleeping habits
C．people lended to sleep mor Peacefully in cold weather
D．winter was a season for people to sleep for months on end
