15."Drink your milk.It's good for you!"You've probably heard that many times,and it's true.Milk contains calcium,which is a necessary nutrient for keeping bones and teeth healthy and strong.The U.S.government even requires milk as part of the National School Lunch Program,saying that students should drink one cup of fat-free or low-fat milk at each meal.Last Thursday,however,a group of doctors asked the government to remove milk from the lunch program.The Physicians Committee for Responsible Medicine (PCRM) says,"Milk is high in sugar,high in fat and high in animal protein,all of which have negative effects on health.""One of the only reasons people talk about dairy,or promote it,is that it is going to help build strong bones."says Dr.Neal Barnard,president of the PCRM.There are better and healthier ways to get calcium such as eating beans,broccoli,cereals and tofu.Orange juice and soymilk that have calcium added to them also supply the nutrient.
Of course,calcium is important for healthy bones and teeth,but your genes,how much vitamin D you take in and getting an hour's worth of exercise every day all play a part.
Some nutritionists disagree with the idea that milk isn't important.Keri Gans,a dietitian,says,"I think it's irresponsible to take away this beverage that children enjoy,especially among those who are unable to meet their nutrient needs for the day,and remove it from the lunch line."
The U.S.government is studying the request of the PCRM,but a decision may be a long way off.Meanwhile,Marion Nestle,a professor at New York University,puts it best:"Milk has nutrients.Other foods have the same nutrients.It's just a food.Like other foods,too much might be a problem."

分析 本文属于说明文阅读,文章主要讲述了美国的传统认为牛奶是对于补钙非常重要的营养品,然而一些专家却呼吁人们少喝牛奶,因为其中有很多的糖和蛋白质,专家认为可以通过吃别的更加健康的食物来给孩子们补钙,文章中也给出了一些相反的观点,总之任何东西吃的太多都是不好的.
解答 41.D 细节理解题,根据第一段Milk contains calcium,which is a necessary nutrient for keeping bones and teeth healthy and strong.The U.S.government even requires milk as part of the National School Lunch Program,saying that students should drink one cup of fat-free or low-fat milk at each meal.可知美国政府要求学生在午餐时间喝一杯牛奶是因为牛奶对骨骼和牙齿的健康和强壮有好处,故选D.
42.A 细节理解题,根据The Physicians Committee for Responsible Medicine (PCRM) says,"Milk is high in sugar,high in fat and high in animal protein,all of which have negative effects on health."可知PCRM认为牛奶中所含的物质会对健康产生负面影响,故选A.
43.C 词义猜测题,根据第四段"I think it's irresponsible to take away this beverage that children enjoy,especially among those who are unable to meet their nutrient needs for the day,and remove it from the lunch line."可知Keri Gans认为把孩子们所喜欢的牛奶从午餐中删除是不负责任的,故选C.
44.B 推理判断题,根据最后一段Meanwhile,Marion Nestle,a professor at New York University,puts it best:"Milk has nutrients.Other foods have the same nutrients.It's just a food.Like other foods,too much might be a problem."可知Marion Nestle认为牛奶只是一种食品,与其他食物一样,牛奶只是普通食物中的一种,故选B.
45.D 主旨大意题,通读全文可知本文主要讲述了是否应该将牛奶从午餐中删除,故选D.

Currently,the world is facing an epidemic (流行病) due to what is considered to be among the most dangerous viruses that humanity has ever faced-the Ebola bleeding virus.Though there were announcements about experimental treatments that were reported to be successful in terms of treating the virus,people around the world continue to die from Ebola.
Ebola was first discovered in 1976in Africa,on the banks of the Ebola River,after which the virus has been named.Back then,there were two major outbreaks of the virus,and this is how people learned about it.There exist several strains of the Ebola virus,some of them are deadly to people,and some are not.
The main symptoms of Ebola can appear in a period between the second and the 21st days of infection,but usually it happens on the eighth through 10th day.Among the symptoms that appear in the first turn,one should mention fever and chills,strong headaches,pain in joints and muscles,and general weakness.These symptoms are not too different from those that people usually experience when catching a severe cold,or flu,so victims may even ignore these symptoms,or try to treat them as a common sickness.However,as the virus keeps progressing,a patient develops nausea(呕吐) with vomiting,diarrhea,chest and stomach pains,red eyes and rash over the body,severe weight loss,and bleeding from almost all bodily openings.
The virus is usually transmitted either through blood,or through waste.Infection through blood usually takes place if a person consumes infested meat,or even touches it (for example,butchering can also lead to infection).Also,there were cases when people got infected after stepping in waste of infected mammals,mostly bats.The other ways of getting infected is through skin by receiving bodily liquids via tiny openings.
Even though there is no specific cure for Ebola,doctors still try to treat it.In order to diagnose Ebola,doctors usually take tests on such diseases as cholera or malaria,because it is difficult to diagnose Ebola based only on symptoms.After the diagnosis has been made,doctors start treating the symptoms,which includes killing infected cells,electrolytes,blood pressure medication,blood transfusions,oxygen treatment,and so on.
Though Ebola is a highly dangerous disease,it is not likely that it will spread globally.It is most deadly in anti-sanitary(不卫生的) conditions,which many African countries have an extremely bad reputation for.As for first world countries,even though there is still no universal cure,they are at much lesser risk than African countries.Though the symptoms of Ebola are severe and getting infected is not difficult,with the correct handling of an outbreak,the virus should not be able to spread.
(71)Introduction | ●Ebola,a dangerous virus,was named after the Ebola River,on whose banks it was first discovered. ●Despite the (72)announced/reported success in the virus treatment,people across the world continue to die from the virus. |
Symptoms | ●In the first turn,the symptoms are (73)similar to those that people experience when they are (74)suffering from a severe cold or flu. ●If not (75)taken seriously,the virus will keep progressing,and things will change for the worse. |
Ways of getting infected | ●People (76)consuming infested meat or touching it can get infected. ●People who step in waste of infected mammals,mostly bats,are (77)likely to get infected. ●People who receive bodily liquids via tiny openings can also get infected. |
Treatment and (78)prevention | ●After making correct diagnosis,doctors start treating the symptoms in many ways,(79)including killing infected cells,blood pressure medication,oxygen therapy,and so on. ●Sanitary living conditions play a significant (80)part/role in preventing the outbreak of the Ebola virus. |
