22、e 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 announced it will do the same.Three years ago, the company introduced the Think C
23、ity 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 carts have been sold so far in 2002.“The bottom line is we dont believe that
24、 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-hour battery recharge time General Motors EVI electric vehicle also had a limi

An electric Toyota RAV4 EV vehicle costs over $42,000 in the US, compared with just $17,000 for the petrol version. Toyota and Nissan
26、 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 senior transport campaigner at UK Friends of the
27、 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 vehicles will help it meet planned new guidelines
28、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 zero-emission and other low-emission vehicle
29、s in the state by 2003. Car manufactures hope the legislation will be rewritten to allow for more low-emission, rather than zero-emission, vehicles.1.what have the Ford motor company, General Motors and Honda done concerning electric cars?A.

34、rothersYoung female chimps are faster and better learners than young male chimps, suggests a new study, echoing learning differences seen in human girls and boys.While young male chimps pass their time playing. Young female chimps carefully study their mothers. As a result, they learn how to fish fo
35、r 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 the Gombe National Park in Tanzania learned “cultural behavior”.The sex diffe
36、rences 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 differences may therefore date back at least to the last common ancestor of
37、 chimpanzees and humans.” they write in the journal 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 video cameras to record this feeding behavior and found that each chim
38、p 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 termites, where the boy chimps were aged 58 months on average. Females w
39、ere 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 frolicking around the termite mound. Behaviors such as playing or swingin
40、g 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 just two main sources of animal protein for chimps the termites or colobus monkeys. “Mature males often hunt monkeys up
41、 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 termite fishing could mean adult females eat better, “They can watch their off

Because young female chimps dont play with their brothers.B. Because young fe

47、inged Robot Learns to FlyLearning how to fly took nature millions of years of trial and errorbut a winged robot has cracked it in only a few hours, using the same evolutionary principles.Krister Wolff and Peter Nordin of Chalmers University of Technology (CUT) in Gothenburg, Sweden, built a winged r
48、obot and set about testing whether it could learn to fly by itself, without any pre-programmed data on what flapping is or how to do it.To begin with, the robot just twitched and jerked erratically. But, gradually, it made movements that gained height. At first , it cheated simply standing on its wi
49、ng tips was one early short cut. After three hours, however, the robot abandoned such methods in favor of a more effective flapping technique, where it rotated its wings through 90 degrees and raised them before twisting them back to the horizontal and pushing down.“This tells us that this kind of evolution is capable of coming up with flying motion,” says Peter Bentley, who works on evolutionary computing at University College London.
