阅读理解。 Tea drinking was common in China for nearly one thousand years before anyone in Europe had ever heard about tea . People in Britain were much slower in finding out what tea was like , mainly because tea was very expensive . It could not be bought in shops and even those people who could afford to have it sent from Holland did so only because it was a fashionable curiosity . Some of them were not sure how to use it . They thought it was a vegetable and tried cooking the leaves . Then they served them mixed with butter and salt . They soon discovered their mistake but many people used to spread the used tea leaves on bread and give them to their children as sandwiches . Tea remained scarce and very expensive in England until the ships of the East India Company began to bring it direct from China early in the seventeenth century . During the next few years so much tea came into the country that the price fell and many people could afford to buy it . At the same time people on the Continent were becoming more and more fond of tea . Until then tea had been drunk without milk in it , but one day a famous French lady named Madame de Sevigne decided to see what tea tasted like when milk was added . She found it so pleasant that she would never again drink it without milk . Because she was such a great lady that her friends thought they must copy everything she did ,they also drank their tea with milk in it . Slowly this habit spread until it reached England and today only very few Britons drink tea without milk . At first , tea was usually drunk after dinner in the evening . No one ever thought of drinking tea in the afternoon until a duchess (公爵夫人) found that a cup of tea and a piece of cake at three or four o'clock stopped her getting 'a sinking feeling' as she called it . She invited her friends to have this new meal with her and so , tea-time was born . 1. This passage mainly discusses .
