In England, afternoon tea, taken between four and five, is the most informal (非正式的) meal of the day. If you are a friend of the family, you may drop in for tea without an invitation or telling that you are coming. Very often it is not served at a table. The members of the family and visitors take tea in the sitting-room. Each person has a cup and saucer, a spoon (汤匙) and a small plate for bread-and-butter and cake. By the way, do not help yourself to cake first, bread-and-butter first, then cake if there is any. Another piece of advice, do not put more than one piece of bread or cake on your plate at the same time.

An ordinary English tea usually consists of ______.
