What it does suggest is that doctors need to be aware of the risks to their older patients if they do become infected，Louie said.“One_of_the_ideas_we_ve_been_trying_to_dispel_(消除)_is_that_this_is_a_mild_disease，” she said in a telephone interview.“In this paper, 30 percent of patients required intensive care. ” Overall, 11 percent of people who were hospitalized died, but among people 50 and older, 18 to 20 percent died.The most common causes of death were viral pneumonia and acute respiratory distress syndrome.As with other studies, obesity appeared to play a great role in the severity of disease.In the 268 cases of adults over 20 whose weight was known, 58 percent were obese, with a BMI(体质指数) of over 30, and of these, 67 percent were very obese, with a BMI of over 40.BMI is equal to weight in kilograms divided by height in meters squared. A person 5 feet 5 inches tall becomes obese at 180 pounds.Louie said in California, the flu has caused shortages of antiviral drugs and of 【解析】细节理解题。根据第三段首句可知患H1N1流感住院的病人的年龄比患季节性流感住院的人的年龄要小。也就是说，患季节性流感住院的病人的年龄比患H1N1流感住院的人的年龄要大。【答案】A3What does the underlined sentence imply?APeople neednt be too worried about H1N1 flu.BPeople take H1N1 flu too seriously.CAll patients with H1N1 flu should be hospitalized.DH1N1 flu can be very severe.【解析】句意理解题。这句话的意思是“我们一直在试图改变人们的这样一个观点，那就是H1N1流感并不严重”，实际上Louie在警告人们：H1N1流感可能会很严重。【答案】D4We can infer that _.Aviral pneumonia is a kind of drugBthe fat people are less likely to become affected with H1 N1 fluCit is very hard to get N95 respirator masks in CaliforniaDH1N1 flu only affects young people【解析】推理判断题。根据最后一段可知，在Califomia抗病毒药物和N95口罩发生短缺，故可推断买这种口罩很困难。【答案】C5What does the author mainly tell us?AH1N1 flu is not just a threat to young people.BH1N1 flu poses a special threat to obese women.CCDCs recommendations for vaccination.DH1N1 flu and seasonal flu.【解析】主旨大意题。根据短文的主题句H1N1 flu can cause severe disease in people of all ages and appears to pose a special threat to those who are obese可知，本文主要讲甲型H1N1流感不是只影响年轻人，而是影响各年龄层次的人群，尤其对肥胖的人构成严重威胁。故A最佳。【答案】ABWith only about 1,000 pandas left in the world，China is desperately trying to clone the animal and save the endangered species.Thats a move similar to what a Texas A&M University researchers have been undertaking for the past five years in a project called “Noahs Ark” Noahs Ark is aimed at collecting eggs，embryos(胚胎)，semen and DNA of endangered animals and storing them in liquid nitrogen.If certain species should become extinct，Dr.Duane Kraemer，a professor in Texas A & Ms College of Veterinary Medicine，says there would be enough of the basic building blocks to reintroduce the species in the future.It is estimated that as many as 2,000 species of mammals，birds reptiles will become extinct in over 100 years.The panda，native only to China，is in danger of becoming extinct in the next 25 years.This week，Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit.They are now trying to implant the embryo into a host animal.The entire procedure could take from three to five years to complete.“The nuclear transfer(核子移植) of one species to another is not easy，and the lack of available (capable of being used) panda eggs could be a major problem，” Kraemer believes.“They will probably have to do several hundred transfers to result in one pregnancy (having a baby)It takes a long time and its difficult，but this could be groundbreaking science if it works.They are certainly not putting any live pandas at risk，so it is worth the effort，” adds Kraemer，who is one of the leaders of the Project at Texas A&M，the firstever attempt at cloning a dog.“They are trying to do something thats never been done，and this is very similar to our work in Noahs Ark.Were both trying to save animals that face extinction.I certainly appreciate their effort and theres
