I. Read the passage and decide whether the statements are true (T) or false (F). New Year’s Eve, 31st December, is a time for the British to eat, drink and party when they celebrate the beginning of a New Year. Many people go to Trafalgar Square in London or a street party in their city. Others visit friends or go to pubs and restaurants, which are very crowded on that night. There is a great atmosphere when everyone waits for Big Ben to strike midnight. Then people kiss and hold hands to sing the traditional Scottish song Auld Lang Syne. Many people also light fireworks at midnight. The main tradition is ‘First Footing’. This means the first person to come into your house after midnight should be a tall dark-haired man. He should bring a piece of coal, some bread, salt or a bottle of whisky to bring good luck to the family. A lot of people also make New Year’s Resolution; they promise to do things like stop smoking or ‘do more exercise’ in the New Year. January 1st (and 2nd in Scotland) is a public holiday so their people can recover from their celebrations. 1. On New Year’s Eve everyone stays at home. 2. People sing a traditional song at midnight. 3. There are no fireworks on New Year’s Eve. 4. It is good luck for a blonde woman to be your first visitor after midnight. 5. Lots of people promise to change in the New Year. 6. New Year’s Day is a public holiday in Britain.
