2013高考英语阅读理解（4月）训练（11）及答案阅读下列短文，从每题所给的选项（a、b、c、d）中，选出最佳选项。ait is obvious that doctors recognize obesity（肥胖） as a health problem. so why is it so hard for them to talk to their patients about it?the results of two surveys, one of primary care physicians and the other of patients, found that while most doctors want to help patients lose weight and think it is their responsibility to do so, they often dont know what to say.“so while doctors may tell patients they are overweight, the conversation often ends there,” said christine c. ferguson, director of the stop obesity alliance. “patients are not told about the possibility of diabetes (a kind of disease),” she said. “and doctors dont feel they have good information to give. they felt that they didnt have adequate tools to address this problem.the lack of dialogue hurts patients, too. the patient survey, of over 1,000 adults, found that most overweight patients dont even know that theyre too heavy. only 39 percent of overweight people surveyed had ever been told by a health care provider that they were overweight.of those who were told they were obese, 90 percent were also told by their doctors to lose weight, the survey found. in fact most have tried to lose weight and may have been successful in the pastand many are still trying, the survey found. and many understand that losing even a small amount of weight can have a positive impact on their health and reduce their risk of obesityrelated diseases like hypertension and diabetes.dr. william bestermann jr., medical director of holston medical group, in kingsport, tenn. , which ranks the 10th in obesity among metropolitan areas in the united states, said the dialogue had to be an ongoing one and could not be dropped after just one mention of the problem. “if youre to be successful with helping your patients lose weight, you have to talk to them at actually every visit about their progress, and find something to encourage them and coach them,” he said.he acknowledged that many doctors tend to be not optimistic.“part of this is that theres this common belief, and doctors are burdened by it, too, that overweight people are weak-willed and just dont have any willpower and are selfindulgent and all that business,” he said. “if you think that way, youre not going to spend time having a productive conversation.”1. what is the stop obesity

参考答案 dbcab *结束3.（2011湖南卷）ca recent study of ancient and modern elephants has come up with the unexpected conclusion that the african elephant is divided into two distinct (不同的) 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 elephants and the african forest elephants 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 3.5metres while the forest elephant has an average shoulder height of 2.5metres. the

elephants as two different units for conservation purpose. since 1950 all african elephants have been conserved as
