【答案解析】[听力原文] Raw Milk Some milk drinkers like what they call 'real milk',/also known as raw milk./This is milk that has not been sterilized./In the United States,/health officials warn that drinking raw milk can be dangerous and even deadly./But the popularity seems to be growing./Supporters say raw milk tastes better than sterilized milk/though not everyone can taste a difference./In all of the fifty states but Michigan,/people are permitted to buy raw milk for animals. 本文的主题为“生牛乳”。文中出现的难词主要有：sterilized, popularity, supporters.要注意美国各州名称的正确书写，此篇文章出现了Michigan(密歇根州)。全文难度不大，第五句中，tastes的主语为raw milk,要用第三人称单数形式，difference前面要加a。
