Passage OneAnimals have different ways of protecting themselves against wintertime weather. Some animals grow heavy coats of fur or feathers, while others dig into the ground to find a warm wintertime home.Some animals spend the winter in a deep sleep because by going to sleep they avoid the time of the year when food is scarce and the temperatures are low. Their sleep is known as hibernation.There is much about hibernation that puzzles scientists. For example, they are wondering how hibernation came into being. Some scientists have explored the possibility that animals release a chemical that starts them hibernating.One thing that scientists are certain about is that animals hibernate only when it is cold. Hibernation is a seasonal practice.Some animals that fall into a wintertime sleep are not true hibernators because they spend only a part of the cold season asleep. Bears, for example, can easily be awakened from their winter nap. They are not true hibernators.Sometimes it is difficult to determine whether a particular animal is a true hibernator. For example, some mice hibernate, but others do not. The same is true of bats. Some of them hibernate. Others do not.36. Hibernation is a seasonal practice. This means it ______.A. takes place only during a particular seasonB. occurs only during the nightC. is a daily practiceD. only happens when a species becomes over-populated
Don’t worry. We have enough time to finish ____ the food and drinks before the guests arrive.A. setting asideB. laying outC. smoothing outD. taking over

Passage 2For centuries in Spain and Latin America, heading home for lunch and a snooze with the familywas some thing like a national right, but with global capitalism standardizing work hours, this idyllichabit is fast becoming an endangered pleasure. Ironically, all this is happening just as researchers arebeginning to note the health benefits of the afternoon nap.According to a nationwide survey, less than 25 percent of Spaniards still enjoy siestas. And likeSpain, much of Latin America has adopted Americanized work schedules, too, with shortened lunchtimes and more rigid work hours. Last year the Mexican government passed a law limiting lunchbreaks to one hour and requiring its employees to work their eight-hour shift between 7 a.m. and 6 p.m.Before the mandate, workers would break up the shift--going home midday for a long break withthe family and returning to work until about 9 or 10 p.m. The idea of siesta is changing in Greece,Italy and Portugal, too, as they rush to join their more "industrious" counterparts in the globalmarket.Most Americans I know covet sleep, but the idea of taking a nap mid-afternoon equates withlaziness, un employment and general sneakiness. Yet according to a National Sleep Survey poll,65percent of adults do not get enough sleep. Numerous scientific studies document the benefits of naptaking, including one 1997 study on the deleterious effects of sleep deprivation in the journal Inter-nal Medicine. The researchers found that fatigue harms not only marital and social relations butworker productivity.According to Mark Rosekind, a former NASA scientist and founder of Solutions in Cupertino,Calif., which educates businesses about the advantages of sanctioning naps, we′ re biologically pro-grammed to get sleepy between 3 and 5 p.m. and 3 and 5 a.m. Our internal timekeeper--called thecircadian clock--operates on a 24-hour rotation and every 12 hours there′s a dip. In accordancewith these natural sleep rhythms, Rosekind recommends that naps be either for 40 minutes or for twohours. Latin American countries, asserts Rosekind, have had it right all along. They′ ve been in syncwith their clocks; we haven′t.Since most of the world is sleep-deprived, getting well under the recommended eight hours anight (adults get an average of 6.5 hours nightly), we usually operate on a kind of idle midday. Napsare even more useful now that most of us forfeit sleep because of insane work schedules, longercommute times and stress, In a study published last April, Brazilian medical researchers noted thatblood pressure and arterial blood pressure dropped during a siesta.The author suggests that most Americans feel that__________.A.Spanish culture is inefficientB.nap-taking will put their jobs at riskC.nap-taking is a sign of lazinessD.they get plenty of sleep

共用题干第二篇Not all sleep is the same every night.We experience some deep,quiet sleep and some active sleep,which is when dreams happen.You might think sleepwalking would happen during active sleep,but a person isn't physically active during active sleep.Sleepwalking usually happens in the first few hours of sleep in the stage called slow-wave or deep sleep.Not all sleepwalkers actually walk.Some simply sit up or stand in bed or act like they're awake when in fact,they're asleep! Most,however,do get up and move around for a few seconds or for as long as haff an hour.Sleepwalkers' eyes are open,but they don't see the same way they do when they're awake and often think they're in different rooms of the house or different places altogether. Sleepwalkers tend to go back to bed on their own and they won't remember it in the morning.Researchers estimate that about 15% of kids sleepwalk regularly. Sleepwalking may run in families（在家族中世代相传）and sometimes occurs when a person is sick, has a fever, is not getting enough sleep,or is stressed（紧张）.If sleepwalking occurs frequently,every night or so,it's a good idea for your mom or dad to take you to see your doctor. But occasional sleepwalking generally isn't something to worry about,although it may look funny or even scary（骇人的）for the people who see a sleepwalker in action.Although occasional sleepwalking isn't a big deal,it's important,of course,that the person is kept safe. Precautions（预防措施）should be taken so the person is less likely to fall down, run into something,or walk out the front door while sleepwalking.When does sleepwalking usually occur?A:During active sleep.B:During deep sleep.C:In the daytime.D:In the early morning.

Right after your evening meal,engage in some sort of physical activity一a sport such as bowling,perhaps.______(48).Then go to bed at your usual time or a little earlier,and you should be able to get a good night's rest without taking a pill.If you can get into the habit of spending your evenings this way,I am sure you will feel less tired during the day.______(49).If so,get up and watch television or do some jobs around your house until you feel sleepy.If you fall asleep and then wake up a few hours later,get up but do not take a sleeping pill.Read a while or listen to the radio,and make yourself a few hours' sleep that night.You will feel better in the morning than you usually feel after taking a pill.______ (50).The most important thing is to avoid taking that nap right after dinner and avoid taking pills.________（50）A:The key to your problem is that long nap after dinnerB:Or get together with friends for an evening of cards and conversationC:At first it may be hard for you to go to sleep without taking a pillD:The next night you will be ready to sleep at an earlier hourE:Having difficulty sleeping is a common problem shared by many people F: The pill is still working in your system when you get up in the morning
