7．"Drink your milk．It is good for you!"You've probably heard that many times，and it is true．Milk contains calcium，which is a necessary nutrient for keeping bones and teeth healthy and strong．The US government even requires milk as part of the National School Lunch Program，saying that students should drink one cup of fat-free milk at each meal．
Last Thursday，however，a group of doctors asked the government to remove the lunch program．The Physical Committee for Responsible Medicine says，"Milk is high in sugar，high in fat and high in animal protein，"all of which have negative effects on health．The PCRM says there were 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．"One of the only reasons people talk about dairy，or promote it at all，is because it is going to help build strong bones．"says Dr．Neal Bamard，president of the PCRM．But milk may not be the best way to get calcium your body needs．
Of course，calcium is important for health bones and teeth，but there are other things that affect your bone strength，such as genes，how much vitamin D you take in and getting an hour's worth of exercise every day．
Some nutritionists disagree with the idea that milk isn't important．Keri Gans，a dietitian，says，"I think it is irresponsible to take this beverage that children enjoy，especially among those who are unable to meet their nutrient needs for the day，and remove it from lunch time．"
The US government is studying the request of the PCRM，but a decision may be a one way to take off．Meanwhile，Marion Nestle，a professor at New York University，put it best："Milk demonstrably has nutrients．Other foods have the same nutrients．It's just a food．Like other foods，too much might be a problem．"
29．Why does the US government ask students to drink one cup of milk at lunch time？
D
A．They have been told many times．
B．They have taken the PCRM's advice．
C．Fat-free or low-fat milk is less expensive．
D．Milk helps build students'strong bones．
30．Which of the following opinions does the PCRM support？A
A．Milk is harmful to students'health．
B．Students should drink more milk each day．
C．Orange juice is higher in calcium than milk．
D．Milk is the best way to get calcium．
31．The underlined word"beverage"in Paragraph 4 most probably meansC．
A．gene        B．idea       C．milk       D．lunch
32．What does the above text mainly talk about？D
A．The best way to get the most calcium．
B．The connection between milk and health．
C．Different opinions about the importance of milk．
D．Whether to take milk off the school-lunch menu．
