EHave you winterized your horse yet? Even though global warming may have made our climate more mild, many animals are still hibernating(冬眠) .It’s too bad that humans can’t hibernate. In fact, as a species, we almost did.Apparently, at times in the past , peasants in France liked a semi-state of human hibernation . So writes Graham Robb, a British scholar who has studied the sleeping habits of the French peasants. As soon as the weather turned cold people all over 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 invention 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 modern invention.In the past , without the artificial light of the city to bathe in, humans went to sleep when it became dark and then woke themselves around midnight. The late night period was known as ”The Watch” It was when people actually kept watch against wild animals ,although many of them simply moved around or visited family and neighbours .According to some sleep researchers, a short period of insomnia(失眠) at midnight is not a disorder .It is normal . Humans can experience another state of consciousness around their sleeping, which occurs in the brief period before 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 upon many of his new ideas.Playing with your sleep rhythms can be adventurous ,as anxiety may set in. Medical science doesn’t 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.67.The example of the French peasants shows the fact that________.A. people might become lazy as a result of too much sleepB. there were signs of hibernation in human sleeping habitsC.people tended to sleep more peacefully in cold weatherD. winter was a season for people to sleep for months on end

共用题干Even Intelligent People Can Fail1 The striking thing about the innovators who succeeded in making our modern world is how often they failed.Turn on a light,take a photograph,watch TV,search the Web,jet across the Pacific Ocean, talk on a celiphone（手机）.The innovators who left us these things had to find the way to success through a maze（错综复杂）of wrong turns.2 We have just celebrated the 125th anniversary of American innovator Thomas Edison's success in heating a thin line to white-hot heat for 14 hours in his lab in New Jersey,U.S.He did that on October 22,1879,and followed up a month later by keeping a thread of common cardboard alight（点亮着的）in an airless space for 45 hours.Three years later he went on to light up half a square mile of downtown Manhattan,even though only one of the six power plants in his design worked when he turned it on,on September 4,1882.3 "Many of life's failures,"the supreme innovator said,"are people who did not realizehow close they were to success when they gave up."Before that magical moment in October 1879,Edison had worked out no fewer than 3,000 theories about electric light,but in only two cases did his experiments work.4 No one likes failure,but the smart innovators learn from it.Mark Gumz,the head of the camera maker Olympus America Inc,attributes some of the company's successes in technology to understanding failure.His popular phrase is:"You only fail when you quit."5 Over two centuries,the most common quality of the innovators has been persistence.That is another way of saying they had the emotional ability to keep up what they were doing.Walt Disney,the founder of Disneyland,was so broke after a succession of financial failures that he was left shoeless in his office because he could not afford the U.S.$1.50 to get his shoes from the repair shop.Pioneering car maker Henry Ford failed with one company and was forced out of another before he developed the Model T car.6 Failure is harder to bear in today's open,accelerated world.Hardly any innovation works the first time.But an impatient society and the media want instant success.When American music and movie master David Geffen had a difficult time,a critic said nastily that the only difference between Geffen Records(Geffen's company)and the Titanic(the ship that went down)was that the Titanic had better music.Actually,it wasn't.After four years of losses,Geffen had so many hits（成功的作品）he could afford a ship as big as the Titanic all to himself.Paragraph 2________A:Importance of learning from failureB:Quality shared by most innovatorsC:Edison's innovationD:Edison's comment on failureE:Contributions made by innovatorsF:Miseries endured by innovators
共用题干第三篇Shouldn't We Know Who Invented the Windshield WiperWe know the famous ones一the Thomas Edison and the Alexander Graham Bells一but what about the less famous inventors?What about the people who invented the traffic light and the windshield wiper（雨刷器）?Shouldn' t we know who they are?Joan Mclean thinks so.In fact,Mclean,a professor of physics at Mountain University in Range,feels so strongly about this matter that she's developed a course on the topic.In addition to learning" who"invented"what",however,Mclean also likes her students to learn the answers to the"why"and"how" questions.According to Mclean,"when students learn the answers to these questions,they are better prepared to recognize opportunities for inventing and more motivated to give inventing a try".Her students agree.One young man with a patent for an unbreakable umbrella is walking proof of McLean's statement."If I had not heard of the story of the windshield wiper's invention,"said Tommy Lee,a senior physics major,"I never would have dreamed of turning my bad experience during a rainstorm into something so constructive."Lee is currently negotiating to sell his patent to an umbrella producer.So,just what is the story behind the windshield wiper? Well,Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy,but Anderson still wanted to see the sights,so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield,she found herself wondering why there couldn't be a built-in device for cleaning the window. Still wondering about this when she returned home to Birmingham,Alabama,Anderson started drafting out solutions. One of her ideas,a lever（操作杆）on the inside of a vehicle that would control an arm on the outside,became the first windshield wiper.Today we benefit from countless inventions and innovations,It's hard to imagine driving without Garrett A.Morgan's traffic light. It'5equally impossible to picture a world without Katherine J. Blodgett's innovation that makes glass invisible.Can you picture life without clear windows and eyeglasses?What can we learn from this article?A:Teachers should help students to sell their inventions to producers.B:How to design a built-in device for cleaning the window.C:We should know less famous inventors.D:We should develop invention courses in universities.

共用题干Some Things We Know About LanguageMany things about language are a mystery,and many will always remain so.But some things we do know.First , we know that all human beings have a language of some sort.There is no race（种族）of men anywhere on earth so backward that it has no language,no set of speech sounds by which the people communicate with one another.Furthermore,in historical times,there has never been a race of men without a language. Second,there is no such thing as a primitive（原始的）language.There are many people whose cultures are undeveloped,who are,as we say,uncivilized,but the languages they speak are not primitive.In all known languages we can see complexities that must have been tens of thousands of years in developing. This has not always been well understood;indeed,the direct contrary has often been stated.Popular ideas of the language of the American Indians will illustrate.Many people have supposed that the Indians communicated in a very primitive system of noises.Study has proved this to be nonsense.There are,or were, hundreds of American Indian languages,and all of them turn out to be very complicated and very old.They are certainly different from the languages that most of us are familiar with,but they are no more primitive than English and Greek.A third thing we know about language is that all languages are perfectly adequate.That is,each one is a perfect means of expressing the culture of the people who speak the language. Finally,we know that language changes.It is natural and normal for language to change;the only languages which do not change are the dead ones.This is easy to understand if we look backward in time. Change goes on in all aspects of language.Grammatical features change as do speech sounds,and changes in vocabulary are sometimes very extensive and may occur very rapidly.Vocabulary is the least stable part of any language.According to the third paragraph,the author thinks that______.A:there exist some primitive languages in the worldB:there are many people who don't have a languageC:no languages in the world haven't been well developedD:there are some languages we know having little complexities
