Unfold it completely if it is a small napkin, or in half, lengthwise (纵向地), if it is a large dinner napkin.If you need to leave the table during the meal, place your napkin on your chair as a signal to your server that you will be return

12、ing. Once the meal is over, place your napkin neatly on the table to the right of your dinner plate. Do not refold it.Use a napkin only for your mouth. Never use it for your nose, face or forehead.Use of utensils (餐具)Start with the knife, fork or spoon furthest from your plate, and work your way in,

13、 using one utensil for each course.If soup is served, remember to spoon away from yourself. This helps stop the drips. Do not put the entire soup spoon in your mouth. Instead, fill a soup spoon about 75 percent with soup, and sip (啜饮) it from the side noiselessly.After finishing dinner, place the kn

19、mostly fuelling automobiles. Coal is still used, mostly in power stations, to cover one-quarter of our energy needs, but it is the least efficient, unhealthiest and most environmentally damaging fossil fuel (矿物燃料). Natural gas reserves could fill some of the gap from oil, but reserves of that will n

20、ot last into the 22nd century either. Most experts predict we will exhaust easily accessible reserves within 50 years. Less-polluting renewable energy sources offer a more practical long-term energy solution. “Renewable“ refers to the fact that these resources are not used faster than they can be re

21、placed.Hydroelectric (水力发电的) power is now the most common form of renewable energy, supplying around 20% of world electricity. Chinas Three Gorges Dam is the largest ever. At five times the size of the USs Hoover Dam, its 26 turbines (涡轮机) will generate the equivalent energy of 18 coal-fired power s

22、tations. It will satisfy 3% of Chinas entire electricity demand.In 2003, the first commercial power station to use tidal (潮汐的) currents in the open sea opened in Norway. It is designed like windmill (风车), but others take the form of turbines.As prices fall, wind power has become the fastest growing

23、type of electricity generationquadrupling (翻两番) worldwide between 1999 and 2005. Modern wind farms consist of turbines that generate electricity. Though it will be more expensive, there is more than enough wind to provide the worlds entire energy needs. Wind farms come in onshore and offshore forms.

24、 They can often end up at spots of natural beauty, and are often unpopular with residents. And turbines are not totally harmlessthey can interfere with radar, alter climate and kill sea birds. Scotland is building Europes largest wind farm, which will power 200,000 homes. The UKs goal is to generate

25、 one-fifth of power from renewable sources, mainly wind, by 2020. But this may cause problems, because wind is unreliable.（分数：10.00）(1).According to the passage, which of the following is the most polluting energy resource?APetroleum. BCoal.CNatural gas.

They cannot reason in the sense that man can, but nature has taken care of the animal kingdom by providing animals with special instincts (本能). One of these instin

29、cts is known as hibernation (冬眠).“Sleeping like a dormouse (榛睡鼠)“ is not only a common saying but is a reality. When winter comes, the dormouse and other hibernating animals have reached a well- nourished state. They eat very well in warmer days laying down fat in the tissues of their bodies and dur

30、ing hibernation this keeps them alive. Safe in their nests, or burrows (地洞), they sleep soundly until the warmth of spring arrives.Bats, tortoises, snakes, frogs, even insects like butterflies, hibernate more or less completely. Some, like the squirrels (松鼠), sleep during coldest weather but are rou

31、sed (弄醒) by a warm spell (暖流). During hibernation, the temperature of an animals body drops drastically. Breathing and heart-beats almost cease.Another instinctive method of avoiding intense cold is to escape by means of migration. Wild swans, seagulls, swallows and cuckoos are a few of the very man

32、y kinds of birds which fly thousands of miles, twice a year, to avoid cold. Many animals, especially those of the Arctic regions, have summer and winter quarters. The Arctic deer of North America, as well as the reindeer (驯鹿) of Europe, move southward towards the forests when winter approaches. They

33、 return to the northern area when the warmth of spring begins to be sensed.There are animals which do not attempt to leave at the first sign of winter cold. Their instinctive means of defense is to dig out a deep burrow, made it soft and warm by padding (填塞) out with straw, leaves, moss and fur. In

34、it they have a “secret place“ containing food which they hope will last the winter through! Animals which fall into this class include the Arctic fox, the rabbit and the little field-mouse.（分数：10.00）(1).How does the dormouse defend itself against cold in winter?AIt moves about to keep warm.BIt grows

35、 thicker fur.CIt stores fat before hibernation.DIt goes to warmer areas.（分数：2.00）A.B.C.D.(2).“Sleeping like a dormouse“ most probably meansAsleeping longer on cold days.Bsleeping badly.Csleeping with a lower heartbeat rate.Dsleeping with little breathing.（分数：2.00）A.B.C.D.(3).During hibernation, anim

36、als breatheAnormally. Bat a slower rate.Cat a faster rate. Dirregularly.（分数：2.00）A.B.C.D.(4).4 According to the passage, “migration“ (paragraph 4) meansAmoving from one place to another at a particular time of the year.Bliving in burrows in winter.Ctraveling in the winter months.Dvisiting foreign co

37、untries.（分数：2.00）A.B.C.D.(5).How does the Arctic fox survive in winter?AIt leaves its burrow and migrates to a warmer land.BIt sleeps soundly inside its burrow in winter.CIt lives on rabbits or field mice.DIt stays in its burrow and lives on the food stored there.（分数：2.00）A.B.C.D.Sleep Necessary for

38、 MemoriesBurning the midnight oil before an exam or interview does harm to the performance according to a recent research which found that sleep is necessary for memories to be taken back into the brain. Agood nights sleep within 30 hours of trying to remember a new task is a required condition of h

39、aving good recall in the weeks ahead, scientists have found.The research, published in the December issue of Nature Neuroscience, showed that it was the act of sleep, rather than the simple passage of time, that was critical for long- term memory formation.“We think that getting that first nights sl

40、eep starts the process of memory consolidation (巩固),“ said Robert Stickgold, a sleep researcher at Harvard Medical School who conducted the latest study.“It seems that memories normally wash out of the brain unless some process nails them down. My suspicion is that sleep is one of those things that

41、does the nailing down,“ Professor Stickgold said.With about one in five people claiming that they are so chronically short of sleep that it affects their daily activities, the latest work emphasizes the less well-understood side effectserious memory impairment (损害).Volunteers in an experiment found

42、it easier to remember a memory task if they were allowed to sleep that night. But for those kept awake, no amount of subsequent sleep made up for the initial loss.Professor Stickgolds team trained 24 people to identify the direction of three diagonal (斜线形的) bars flashed for a sixtieth of a second on

43、 a computer screen full of horizontal (水平的) stripes.Half of the subjects were kept awake that night, while the others slept. Both groups were allowed to sleep for the second and third nights to make up for any differences in tiredness between the volunteers.Those who slept the first night were signi

44、ficantly and consistently better at remembering the task while the second group showed no improvement despite enjoying two nights of catch-up sleep.（分数：10.00）(1).The research published in Nature Neuroscience showed that what was essential to the formation of long-term memory wasAintelligence. Btime.

48、r than those who did not.（分数：2.00）A.B.C.D.TapeStore: ANew Tape Storage SystemTapeStore is a new kind of tape storage system which can store up to 6,000 computer tapes. No other tape storage system can hold as many computer tapes as TapeStore. The tapes look exactly like video cassettes. Many hundred

49、s of data files can be stored on each tape, up to a maximum of 500 million bytes (字节) of data. If you stored the same amount of information on paper, you would need nearly 4. 5 billion printed pages.The machine is a tall black box with a mechanical arm. The machine is 2.5 metres high and 3.0 metres wide. This is how it works. Each tape has a code printed on it. You feed the code number into TapeStore, which then looks for the code. As soon as TapeStore locates th
