Finding Yourself without GPSAs more mobile phones tap into the Internet, people increasingly turn to them for location-centric services like getting directions and finding nearby restaurants.

8、 While Global Positioning System (GPS) technology provides excellent accuracy, only a fraction of phones have this capability. Whats more, GPS coverage is spotty in dense urban environments, and inphone receivers can be slow and drain a phones battery.To sidestep this problem, last week Google added

9、 a new feature, called My Location, to its Web-based mapping service. My Location collects information from the nearest cell-phone tower to estimate a persons location within a distance of about 1,000 meters. This resolution is obviously not sufficient for driving directions, but it can be fine for

10、searching for a restaurant or a store. “A common use of Google Maps is to search nearby,“ says Steve Lee, product manager for Google Maps, who likened the approach to searching for something within an urban zip code, but without knowing that code. “In a new city, you might not know the zip code, or

11、even if you know it, it takes time to enter it and then to zoom in and pan around the map.“Many phones support software that is able to read the unique identification of a cell-phone tower and the coverage area that surrounds it is usually split into three regions. Lee explains that My Location uses

12、 such software to learn which tower is serving the phoneand which coverage area the cell phone is operating in. Google also uses data from cell phones in the area that do have GPS to help estimate the locations of the devices without it. In this way, Google adds geographic information to the cellpho

13、ne towers identifiers that the company stores in a database. As the database grows, says Lee, the service will become more accurate. It will never be as accurate as GPS, but he expects that it could eventually find a person within a couple hundred meters.（分数：7.00）(1).All the cell phones are able to

19、n EffectSpace is a dangerous place, not only because of meteors (流星)but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth light, gets through, and this is essential for plants to make the food that we eat. Heat, too, makes our environment

20、 endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation, but their spacesuits or the walls of their spacecrafts, if they are inside, do prevent

21、a lot of radiation damage.Radiation is the greatest known danger to explorers in space. The unit of radiation is called “rem“ (“雷姆”). Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged, the figure of 60 reins has been agreed on. The troub

22、le is that it is extremely difficult to be sure about radiation damage-a person may feel perfectly well, but the cells of his or her sex organs may be damaged ,and this will not be discovered until the birth of deformed(畸形的)children or even grandchildren. Missions of the Apollo flights have had to c

23、ross belts of high radiation and, during the outward and return journeys, the Apollo crew accumulated a larger amount of reins. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they

24、 spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage clone by radiation ,but no really effective ones have been found so far.（分数：15.00）(1).According to the first paragraph, the atmosphere is essential to man in that_

29、ffee late in the day will play havoc with your sleep. As well as being a stimulant, caffeine interrupts the flow of melatonin, the brain hormone that sends people into a sleep.Melatonin levels normally start to rise about two hours before bedtime. Levels then peak between 2 am and 4 am, before falli

30、ng again. “Its the neurohormone that controls our sleep, and tells our body when to sleep and when to wake,“ says Maurice Ohayon of the Stanford Sleep Epiderniology Research Center at Stanford University in California. But researchers in Israel have found that caffeinated coffee halves the bodys lev

31、els of this sleep hormone.Lotan Shilo and a team at the Sapir Medical Center in Tel Aviv University found that six volunteers slept less well after a cup of caffeinated coffee than after drinking the same amount of decal On average, subjects slept 336 minutes per night after drinking caffeinated cof

32、fee, compared with 415 minutes after decaf. They also took haft an hour to drop off-twice as long as usual - and jigged around in bed twice as much.In the second phase of the experiment, the researchers woke the volunteers every three hours and asked them to give a urine sample. Shilo measured conce

33、ntrations of a breakdown product of melatonin. The results suggest that melatonin concentrations in caffeine drinkers were half those in decaf drinkers. In a paper accepted for publication in Sleep Medicine, the researchers suggest that caffeine blocks production of the enzyme that drives melatonin

34、production.Because it can take many hours to eliminate caffeine from the body, Ohayon recommends that coffee lovers switch to decaf after lunch.（分数：15.00）(1).Which of the following tells us how caffeine affects sleep?A. Caffeine blocks production of the enzyme that stops melatonin production.B. Caff

The proof that the subjects took half an hour to fall asleep.（分数：3.00）A.B.C.D.(3).What does the experiment mentioned in paragraph 4 prove?A. There are more enzyme

37、s in decal drinkers urine sample.B. There are more melatonin concentrations in caffeine drinkers urine sample.C. Decaf drinkers produce less melatonin.D. Caffeine drinkers produce less sleep hormone.（分数：3.00）A.B.C.D.(4).The author of this passage probably agrees thatA. coffee lovers sleep less than

38、those who do not drink coffee.B. we should not drink coffee after supper:C. people sleep more soundly at midnight than at 3 am.D. if we feel sleepy at night, we should go to bed immediately.（分数：3.00）A.B.C.D.(5).The author mentions “pick-me-up“ to indicate thatA. melatonin levels need to be raised.B.

One is why human beings flock there by thousands, only to prostrate(俯卧) themselves in dense packs of glistening flesh. The other

40、 is why the sand goes there. Strange as it seems, oceanographers have never really understood why sand piles up on the shore. Now Douglas Inman and Daniel Conley think they have solved the puzzle.The puzzle had to do with waves. Though it might seem intuitive that waves carry water to shore, and san

41、d along with it, its not that simple. The crest(浪尖)of a passing wave lifts a given hit of water upward and landward, but the ensuing trough(波谷) pushes the water back down and Out to sea. Near the bottom, there the sand is, the water was always assumed to just slide back and forthand the sand with it

42、. “If you take a very aloof look at a beach,“ says Inman, “youll realize that if the two motions move sand back and forth the same amount, then all the sand should end up in deep water.So for beaches to exist, the crests onshore flow must somehow move enough sand up the beach to counter the seaward

43、tug of both the trough and gravity . The pressure changes in the sand bed, Inman and Conley think, are the key to beach creation. They found that sand doesnt just slide back and forth with each passing wave. Under a trough, it does slide seaward, in a thin layer just above the bottom. But under a cr

44、est its movement is often more elaborate. The higher pressure under a cresthigher because the water is piled higherforces water into the porous(多孔的) sand. This creates strong whirlpools just above the sand, which help loosen it. As the crest passes overhead, the sand first rushes across the bottom;

45、then it abruptly turns violent lifting off the bottom in large, boiling bunches. Finally, just after the crest passes, the sand explodes up into the great water column. The boiling and rushing move more sand than the backsliding under a trough, so theres a net movement of sand toward the shore.（分数：1

46、5.00）(1).What is the primary purpose of this passage?A. To explain why sand piles up on the beaches.B. To explain why men only prostrate in the sea.C. To propose a new explanation of a phenomenon.D. To refute a misconception.（分数：3.00）A.B.C.D.(2).Which of the following statements is NOT true accordin

47、g to the passage?A. Tile pressure changes in the sand bed are the most important factor in the creation of beach.B. The crest pushes water seaward.C. People take it for granted that waves carry water and sand to the beach.D. The high pressure under a crest forms strong whirlpools above the sand.（分数：

48、3.00）A.B.C.D.(3).Which of the following is not a step of beach creation?A. Water is forced into sand by the high pressure under a crest.B. Strong whirlpools loosen the sand.C. The sand is first at the bottom when a crest passes.D. More sand is pushed back to the sea.（分数：3.00）A.B.C.D.(4).Which of the
