If the festive season is all about filing up on the things you like that are bad for you, then the new year is the “Detox season“ when people across the western world ado

8、pt special diets to lose weight and get rid of the vague feeling that they have spent the last few weeks poisoning themselves.But are Detox diets really necessary? After all, the body itself gets rid of unwanted substances. Thats what the liver and kidney are for.“The Detox fad or fads, as there are

9、 many methods, is an example of the capacity of people to believe in and pay for magic despite the lack of any sound evidence,“ says Martin Wiseman, professor of human nutrition at the University of Southampton in the UK.Most of the pills, juices, teas and oils that are sold for their detoxifying ef

10、fects on the body have no scientific foundation for their claims, according to the research. People would be better off having a glass of water and going to bed early.Detox diets may be magic rather science, but they are the kind of magic which many people want to perform. That may have something to

11、 do with the western diet in general.Scientists and dieticians argue that the benefits people feel are not due to their body getting rid of excessive toxins but are due to changing from what is likely to have been a “poor“ diet.Having fewer headaches, for example, is probably the result of being ful

12、ly hydrated due to drinking so much water and better skin may be due to eating more fruit and vegetables.Detox diets may also be dangerous, as they may deprive vulnerable groups-pregnant women, for instance, or growing teenagers of the kind of nutrients they need.Yet their popularity continues to ri

13、se. This may be something to do with the way that food works within many western cultures. Generally, a countrys food develops along with its economy and society. Food becomes part of a persons cultural identity.In some countries, this link has been broken. In the UK, for example, rapid industrializ

14、ation in the 18th and 19th centuries saw millions of people move from the countryside to the towns interrupting the development of a national cuisine. The United States, a country of immigrants from many different places, has found it hard to develop a national cuisine. In both places, comparatively

15、 few people cook for themselves and food supply is dominated by big processing and agribusiness companies.Detox diets are more popular in these countries than in places like France and Italy, where strong links between food and national culture remain, and where far more people regularly cook for th

16、emselves instead of buying processed foods.Perhaps Detox diets are successful because many westerners have lost mast in what they eat. On the other hand, they may help re-introduce people to the kind of food that is necessary for a healthy diet. And after learning that, they wont poison themselves i

17、n the first place.This would mean radical changes in the way that people eat across the west. And that would be an unwelcome development for the food industry. From the business point of view, it is much better to sell people the problem and then sell them the solution.（分数：7.00）(1).Detox begins afte

19、y take.（分数：1.00）A.RightB.WrongC.Not mentioned(3).Both the UK and the USA lack a national cuisine as a result of similar historical development.（分数：1.00）A.RightB.WrongC.Not mentioned(4).The French and the Italians cook for themselves more often than the British and the Americans, which helps them to

20、keep the link between food and their culture.（分数：1.00）A.RightB.WrongC.Not mentioned(5).On the whole the eastern people like the Chinese and the Japanese have a stronger link between their food and their culture than the western people.（分数：1.00）A.RightB.WrongC.Not mentioned(6).A positive effect of De

25、 abandonment of electric cars effectively signals the end of the road for the technology, analysts say.General Motors and Honda ceased production of battery-powered cars in 1999, to focus on fuel cell and hybrid electric gasoline engines, which are more attractive to the consumer. Ford has now annou

26、nced it will do the same.Three years ago, the company introduced the Think City two-seater car and a golf cart called the THINK, or Think Neighbor. It hoped to sell 5,000 cars each year and 10,000 carts. But a lack of demand means only about 1,000 of the cars have been produced, and less than 1,700

27、carts have been sold so far in 2002.“The bottom line is we dont believe that this is the future of environment transport for the mass market,“ Tim Holmes of Ford Europe said on Friday. “We feel we have given electric our best shot. “The Think City has a range of only about 53 miles and up to a six-h

28、our battery recharge time. General Motors EVI electric vehicle also had a limited range, of about 100 miles.The very expensive batteries also mean electric cars cost much more than petrol-powered alternatives. An electric Toyota RAV4 EV vehicle costs over $42,000 in the US, compared with just $17,00

29、0 for the petrol version. Toyota and Nissan are now the only major auto manufacturers to produce electric vehicles.“There is a feeling that battery electric has been given its chance. Ford now has to move on with its hybrid program, and that is what we will be judging them on, “ Roger Higman, a seni

30、or transport campaigner at UK Friends of the Earth, told the Environment News Service.Hybrid cars introduced by Toyota and Honda in the past few years have sold well. Hybrid engines offer greater mileage than petrol-only engines, and the batteries recharge themselves. Ford says it thinks such vehicl

31、es will help it meet planned new guidelines on vehicle emissions in the US.However, it is not yet clear exactly what those guidelines will permit. In June, General Motors and Daimler Chrysler won a court injunction, delaying by two years Californian legislation requiring car-makers to offer 100,000

32、zero-emission and other low-emission vehicles in the state by 2003. Car manufacturers hope the legislation will be rewritten to allow for more low-emission, rather than zero-emission, vehicles.（分数：15.00）(1).What have the Ford motor company, General Motors and Honda done concerning electric cars?（分数：

38、himps carefully study their mothers. As a result, they learn how to fish for tasty termite snacks over two years before the boys.Elizabeth Lonsdorf, now at Lincoln Park Zoo in Chicago, US, and colleagues at the University of Minnesota, Saint Paul, spent four years watching how young chimpanzees in t

39、he Gombe National Park in Tanzania learned “cultural behavior“.The sex differences in learning behavior were “consistent and strikingly apparent“, says the team. The researchers point out that similar differences are seen in human children with regard to skills such as writing. “A sex-based learning

40、 differences may therefore date back at least to the last common ancestor of chimpanzees and humans,“ they write in the Nature.Chimps make flexible tools from vegetation and then insert them into termite mounds, extract them and then munch the termites clinging onto the tool. The researchers used vi

41、deo cameras to record this feeding behavior and found that each chimp mother had her own technique, such as how she used tools of different lengths.Analysis of the six infants whose ages were known showed that girl chimps were an average of 31 months old when they succeeded in fishing out their term

42、ites, where the boy chimps were aged 58 months on average. Females were also more skillful at getting out more termites with every dip and used techniques similar to their mothers while males did not.Instead of studying their mothers, the boy chimps spent a significantly greater amount of time froli

43、cking around the termite mound. Behaviors such as playing or swinging might help the male infants later in life when typically male activities like hunting or fighting for dominance become important, suggest the researchers.Lonsdorf adds that there are just two main sources of animal protein for chi

44、mps-the termites or colobus monkeys. “Mature males often hunt monkeys up trees, but females are almost always either pregnant or burdened with a clinging infant. This makes hunting difficult,“ she says. “Adult females spend more time fishing for termites than males.“ So becoming proficient at termit

45、e fishing could mean adult females eat better. “They can watch their offspring at the same time. The young of both sexes seem to pursue activities related to their adult sex roles at a Very young age. /（分数：15.00）(1).Why do young female chimps learn faster than young male chimps at fishing for termit

46、es?（分数：3.00）A.Because young female chimps dont play with their brothers.B.Because young female chimps begin to study their mothers earlier.C.Because young male chimps never learn to fish for termites.D.Because young male chimps are not interested in termites.(2).What are the tools with which chimps
