     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 In-dia 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 af-ford 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 her friends thought they must copy everything she did, so they also drank their tea

with milk in it. Slowly this habit spread until it reached England and today only very few Brit-ons (British

people) 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.
