         Dear Rose,
         How are you?
         I like your programmes very much. They're very interesting and I can learn a lot from them. I
like travelling and I have won a free four-week trip to England, but I know little about the British way
of life. Would you please write to tell me something about the British meals?
         Thank you.
                                                                                                                                  Yours,
                                                                                                                                Wang Lin

        Dear Wang Lin,
        It's very helpful to know something about the British meals before travelling. In many English
houses, people eat four meals a day. They are breakfast, lunch, tea and dinner.
        Breakfast takes place at any time from 7:00 to 9:00 in the morning. They usually have eggs,
bread with butter, cheese and so on. English people drink tea or coffee at breakfast. Lunch comes at
one o'clock. It can be a hamburger or a three-course (三道菜) meal. Afternoon tea is between 4:00
pm and 5:00 pm. Dinner begins at about half past seven. The first course is soup. The next is often
meat or fish with vegetables. Then come fruits of different kinds: apples, pears, bananas and so on.
But not all English people eat like that. Some of them have their dinner in the middle of the day. Their
meals are breakfast, dinner, tea and supper. And all these meals are usually simple.
         Wish you a good time in England!
                                                                                                                                 Yours,
                                                                                                                                  Rose
