8、d unfortunate that in our modern era of technologic and scientific achievement, there is no adequate explanation for a seemingly simple question: “why do people become too fat and what can be done to prevent it?“ about 50 million men and 60 million women between the ages of 18 and 79 are “too fat“ a

9、nd need to reduce excess weight. This amount to about 377 million kg of excess fat for men and 667 million kg for women, or a total of t044 million kg (2297 million 1b) for the United States adult population! If the overfat men and women dieted by consuming 600 fewer calories each day to reduce to a

10、 “normal“ value of body fat (achievable in 68 days for men and 101 days for women), the reduced caloric intake would equal 5.7 trilling calories. Translating this into fossil fuel energy and considering such factors as the energy required to plant, cultivate, harvest, feed, process, transport, whole

11、sale, retail, acquire, store and cook the food, the annual energy savings would be equal to that required to supply the residential electric demands of Boston, Chicago, san Francisco and Washington DC, or 13 billion gallons of gasoline to fuel 900,000 autos per year. Until recently, the major cause

12、of obesity was believed to be overeating. However, if gluttony (贪食) and overindulgence were the only factors associated with an increase in body fat, the easiest way to permanently reduce would surely to be cut back on food. Of course, if it were that simple, obesity would soon be eliminated as a ma

13、jor health problem. There are obviously other factors operative such as genetic, environmental, and social influences. However, these causes probably overlap. It seems fairly certain that the treatment procedures devised so far, whether they be diets, surgery, drugs, psychologic methods, or exercise

14、, either alone or in combination, have not been particularly successful in solving the problem on a long-term basis. There is nonetheless, optimism that as researchers continue to investigate the many facets of. obesity, as well as to test and quantify various treatment modes, significant progress c

Although Benjamin Franklin demonstrated lightning as an enormous electrical discharge more than 200 years ago, many puzzles still surround this powerful phenom

20、enon.2Lightning is generated when electrical charges separate in rain clouds, though processes are still not fully understood. Typically, positive charges build at the cloud top, while the bottom becomes negatively charged. In most instances of cloud-to-ground lightning, the negatively charged lower

21、 portion of the cloud repels negatively charged particles on the grounds surfaces, making it become positively charged, The positive charge on the ground gathers at elevated points.3A flow of electrons begins between the cloud and earth. When the voltage charge becomes large enough, it breaks throug

22、h the insulating barrier of air, and electrons zigzag earthward. We see the discharge as lightning.4Lightning can occur within a cloud, between clouds, or between clouds and the ground. The first variety, intra-cloud lightning, is the most frequent but is often hidden from our view. Cloud-to -ground

23、 lightning, making up about 20 percent of lightning discharges, is what we usually see lightning comes in several forms, including sheet, ribbon, and ball, Intra-cloud lightning can illuminate a cloud so it looks like a White sheet, hence its name. When cloud-to-ground lightning occurs during strong

24、 winds, they can shift the lightning channel sideways, so it looks like a ribbon. The average lightning strike is more than 3 miles long and can travel at a tenth of the speed of light. Ball lightning, the rarest and most mysterious form, derives its name from the small luminous ball that appears ne

25、ar the impact point, moves horizontally, and lasts for several seconds.5Thunder is generated by the tremendous heat released in a lightning discharge second. This sudden heating acts as an explosion, generating shock waves we hear as thunder.6About 2,000 thunderstorms are occurring in the world at a

26、ny time, generating about 100 lightning strikes every second, or 8 million daily. Within the United States, lightning strikes are estimated at 20 million a year, or about 22,000 per day. You have a 1-in-600,000 chance of being struck by lightning during your lifetime. Lightning can strike twice or m

27、ore in the same spot. The Empire State Building in New York is struck by lightning about two dozen times annually.7You can measure how far you are from a lightning strike by counting the seconds between viewing the flash and hearing the bang, and then dividing by five. This approximates the mileage.

31、、第 4部分：阅读理解(总题数：0，分数：0.00)五、第一篇(总题数：1，分数：15.00)Dancing in the StreetsIf there is one thing certain to get Brazilians on their feet, it is the Rio Carnival (狂欢节). Held in Rio de Janeiro, the countrys biggest city, the carnival began on February 20 when the mayor gave key of the city to Rei Momo-the L

32、ord of Misrule (无序之皇)On his orders, each year people turn the city into a paradise of dance and music. The following six days are so fun of parades, street dancing, fantastic clothes and partying (聚会) that many people forget about eating and sleeping.“It was the passion of the carnival that attracte

33、d me to Brazil and made me settle down in Rio. “ said Bob Nadkarni, a British man who has lived in the city for several years. For many Brazilians, the centerpiece of the carnival is samba (桑巴舞) , a typical Brazilian dance. Every year, tens of thousands of visitors and locals show off their passion

34、and energy in the streets, following the beat (节拍) of the Latin music.The climax to this street party is the float(彩车) parade, in which floats decorated with tons of fresh flowers by various samba schools and local communities move through the city. On the top of each float stands the candidate for

35、the Drum Queen, who is chosen at the end of the party.While most people are free to enjoy the celebrations. Rios police officers have to keep a clear head. Following the murder of three officers in a gunfight early last week, the Brazilian Government has tightened security in Rio. The street fightin

36、g, robbery and sex crimes that accompany the carnival are very difficult to police.Carnivals began in ancient Rome as a celebration at which people fed wild wolves, in honor of the citys founder who was said to have been raised by a she-wolf. Brazil gave new life to this tradition and so despite the

37、 troubles, the carnival will remain a symbol of the countrys culture.（分数：15.00）(1).According to the passage, during the Carnival people in Rio did all of the following EXCEPTAdancing in the streets.Bputting on colorful clothes.Ceating a lot of food.Dholding exciting parades.（分数：3.00）A.B.C.D.(2).How

41、culating the numbers of the threatened animals such as elephants, “ say African and American researchers. The error occurs because of a flaw in the way they estimate animal numbers from the piles of dung(粪)the creatures leave behind. The mistake could lead researchers to think that there are twice a

42、s many elephants as there really are in some regions according to Andrew Plumptre of the Wildlife Conservation Society(WCS) in New York. Biologist Katy Payne of Cornell University in Ithaca, New York, agrees. “We really need to know elephant numbers and the evidence that we have is quite indirect, “

43、says Payne, who electronically tracks elephants Counting elephants from planes is impossible in the vast rainforests of Central Africa. So researchers often estimate elephant numbers by counting dung piles in a given area. They also need to know the rate at which dung decays because its extremely di

44、fficult to determine these rates. However, researchers counting elephants in one region tend to rely on standard decay rates established elsewhere. “But researchers at the WCS have found that this decay rate varies from region to region depending on the climate and environment. Using the wrong value

45、s can lead the census astray(离开正道),“ says Plumptre. He and his colleague Anthony Chifu Nchanji studied decaying elephant dung in the forests of Cameroon. They found that the dung decayed between 55 and 65 per cent more slowly than the dung in the rainforests of neighbouring Gabon. If researchers use

46、 decay rates from Gabon to count elephants in Cameroon, they would probably find more elephants than are actually around. “This could mean estimates in Cameroon are at least twice as high as those derived from decay rates calculated locally,“ says Plumptre “However accurate your dung density estimat

47、e might be the decay rate can severely affect the result.“ Plumptre also says that the dung-pile census should be carried out over a region similar in size to an elephants natural range. The usual technique of monitoring only small, protected areas distorts numbers because elephants move in and out

48、of these regions, he says“ If the elephant population increases within the protected area, you can not determine whether it is a real increase or whether it is due to elephants moving in because they are being poached(入侵偷猎)outside. “ Plumptre says that similar problems may also affect other animal c

49、ensus studies that rely on indirect evidence such as nests, tracks or burrows(地洞).（分数：15.00）(1).The word “threatened“ in the first sentence of the first paragraph could be best replaced by A. “endangered“. B. “frightened“. C. “killed“. D. “angered“.（分数：3.00）A.B.C.D.(2).Why do researchers estimate elephant numbers in an area by counting dung piles? A.
