    So where does all the cheese come from, and why do makers keep it The answer is that farmers make too much milk in America. People can keep the cheese for a long time. So milk makers are turning the extra (额外的) milk into different types of cheese, such as Cheddar, Colby, Monterey Jack, and Swiss. People can eat different cheeses and more people buy the cheeses.
    Americans drink less milk than before. In 1975, an American drank about 29 gallons (110 liters) of milk a year. In 2017, that number was down to about 17 gallons (66 liters). And now, for many reasons, farmers can get more milk from their cows. So there is more and more extra milk. When there’s too much of something, the price (价格) usually goes down. And the price of milk also goes down. So farmers don’t make as much money from their milk as before.
    The US keeps the most cheese in the world for about 100 years. The 1.4 billion pounds of cheese is enough to build a cheese house. It’s amazing.
    26．Why do milk makers in the US keep lots of cheese
    A．There is too much milk.
    B．There are too many cows.
    C．Cheese is Americans’ favourite food.

    5.D　[乙醇和乙烷都含有乙基(—CH2CH3)，但羟基(—OH)是乙醇的官能团，其决定乙醇的化学性质，而乙烷不含官能团，显然二者的化学性质不同。]
    6.B　[苯乙烯含有，官能团和乙醇不同；丙三醇含有—OH，官能团和乙醇相同；丙酮含有，官能团和乙醇不同；乙醚中含有，官能团和乙醇不同，故选B。]
    7.C　[①乙醇的沸点低，易挥发，若饮酒，呼出的气体中含有乙醇，与测定原理有关；③K2Cr2O7遇乙醇迅速生成蓝绿色的Cr3+，Cr元素的化合价由+6价降低为+3价，K2Cr2O7被还原，则乙醇具有还原性，与测定原理有关。]
    8.B　[铜丝燃烧生成黑色的CuO，如遇稀硫酸和盐酸，发生反应：CuO+2H+Cu2++H2O，使质量减少；遇酒精又生成Cu单质，质量不变。]
    9.B
    10.D　[乙醇中羟基上的氢的活泼性小于水中氢的活泼性，所以钠与乙醇反应较缓慢，不会熔化成小球，故A错误；乙醇不显碱性，向其水溶液中滴入几滴酚酞，溶液不变红色，故B错误；将灼热的铜丝伸入乙醇中，铜丝表面由黑色变为红色，不会溶解，故C错误；乙醇具有还原性，能使酸性高锰酸钾溶液褪色，故D正确。]
    11.D　[乙醇和水互溶，不能将碘从碘水中萃取出来。]
