species. the discovery was made by researchers at york and harvard universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephantsthe asian elephant, african forest elephant, and african savanna elephant. once they obtained dna sequences (序列) from two fossils (化石), mammoths and mastodons, the team compared them with dna from modern elephants. they found to their amazement that modern forest and savanna elephants are as distinct from each other as asian elephants and mammoths. the scientists used detailed genetic analysis to prove that the african savanna elephant and the african forest elephant have been distinct species for several million years. the divergence of the two species took place around the time of the divergence of asian elephants and woolly mammoths. this result amazed all the scientists. there has long been debate in the scientific community that the two might be separate species, but this is the most convincing scientific evidence so far that they are indeed different species. previously, many naturalists believed that african savanna elephants and african forest elephants were two populations of the same species, despite the elephants significant size differences. the savanna elephant has an average shoulder height of 3. 5 metres while the forest elephant has an average shoulder height of 2. 5 metres. the savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant. but the fact that they look so different does not necessarily mean they are different species. however the proof lay in the analysis of the dna. alfred roca, assistant professor in the department of animal sciences at the university of illinois, said, “we now have to treat the forest and savanna elephants as two different units for conservation purposes. since 1950, all african elephants have been conserved as one species. now that we know the forest and savanna elephants are two very distinctive animals, the forest elephant should become a bigger priority (优先) for conservation purposes.”1. one of the fossils studied by the researchers is that of.a.

dcaacaafter a terrible electrical accident, which caused him to become both blind and deaf, the whole world became completely dark and quiet for robert edwards for almost ten years. the loss of sight and hearing threw him into such sorrow that he tried a few times to put an end to his life. his family, especially his wife, did their best to tend and comfort him and finally he regained the will to

lightning. witnesses thought he was dead but he woke up some 20 minutes later lying face down in muddy water at the base of the tree. he was trembling badly, but when he opened his eyes, he could hardly believe what he saw: a plough and a wall. when mrs. edwards came running up to him, shouting to their neighbors to call for help, he could see her and hear her voice for the first time in

got from the lightning. however, none of them could give a convincing answer as to why this should have happened. the only reasonable explanation given by one doctor was that, since robert lost his

clothes addict.” he jokes. “i used to carry a fresh suit to work with me so i could change if my clothes got wrinkled.” today david wears casual clotheskhaki pants and a sports shirtto the office. he hardly ever wears a necktie. “i am working harder than ever.” david says, “and i need to feel comfortable.”more and more companies are allowing their office workers to wear casual clothes to work. in the united states, the change from formal to casual office wear has been gradual. in the early 1990s, many companies allowed their employees to wear casual clothes on friday（but only on friday）. this became known as “dress-down friday” or “casual friday”. “what started out as an extra one-day-a-week benefit for employees has really become an everyday thing.” said business consultant maisly jones.why have so many companies started allowing their employees to wear casual clothes? one reason is that its easier for a company to attract new employees if it has a casual dress code.” “a lot of young people dont want to dress up for work,” says the owner of a software company, “so its hard to hire people if you have a conservative（保守的）dress code.” another reason is that people seem happier and more productive when they are wearing comfortable clothes. in a study conducted by levi strauss and company, 85 percent of employers said that they believe that casual dress improves employee morale（心境，士气）. only 4 percent of employers said that casual dress has a negative influence on productivity. supporters of casual office wear also argue that a casual dress code helps them save money. “suits are expensive, if you have to wear one every day,” one person said. “for the same amount of money, you can buy a lot more casual clothes.”9. david smith refers to himself as having been “a clothes addict,” because _.a. he often wore khaki pants and a sports shirtb. he couldnt stand a clean appearancec. he wanted his clothes to look neat all the timed. he didnt want to spend much money

“therere too many cars, and you cant move around a lot.”professor cyrus shahabi also knows about traffic jams. he lives more than 65 kilometers from his office at the university of southern california, in los angeles. he is always late even with the help of a navigation (导航) system.he decided to develop a program called clearpath for that. he says his program uses historical data to predict traffic conditions even before the driver leaves the house.“whats unique is that we use a lot of data thats currently become available including traffic data, weather data, and we analyze that so that we can predict whats going to happen in front of you when you leave home.”professor shahabi says his system does more than just respond to current traffic conditions. with clearpath, he says,
