The US has lots of cheese. Milk makers in the US keep about 630 million kilograms of cheese.
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.
D．Farmers want to open more cheese stores.
27．What does the underlined word “types” in Paragraph 2 mean
A．Prices. B．Names. C．Kinds. D．Colours.
28．We can learn from Paragraph 3 that ________.
A．Americans didn’t like drinking milk in 2017
B．Farmers can get more money by selling milk than before
C．Americans drank less milk in 2017 than in 1975
D．The price of milk becomes more and more expensive
29．Which of the following is TRUE according to the passage
A．People can keep cheeses longer than milk.
B．The price of milk becomes high in the US.
C．An American drank about 110 liters of milk a year in 2017.
D．Milk makers in the US keep about 650 million kilograms of milk.
30．Which can be the best title for the passage
A．The Milk in US
B．The Cheese in the US
C．A Cheese House in US
D．The Hard-working Farmers in US
