British Traditions
Clubs. One of English traditions is clubs. A club is an association of people who like to meet together to relax and discuss things. These people are usually upper-class men or men connected with the government or other powerful organizations which control public life and support the established order of society. However, there are clubs of people not connected with the ruling circles, for example cultural clubs, whose members are actors, painters, writers and critics and their friends. In a word, clubs are organizations which join people of the same interests. A club usually owns a building where members can eat, drink, and sometimes sleep.
Traditional ceremonies. A lot of traditional ceremonies have been preserved since old times and are still regularly observed. Among them is the Ceremony of the Keys.
The Ceremony of the Keys. The Ceremony of the Keys dates back 700 years and has taken place every night since that time. It was never interrupted even during the air-raids by the Germans in the last war. Every night, at 9.53 p.m. the Chief Warder of the Yeomen Warders (Beefeaters) of the Tower of London lights a candle lantern and goes, accompanied by his Escort, towards the Bloody Tower. In his hand the Chief Warder carries the keys, with which he locks the West Gate and then the Middle Tower. Then the Chief Warder and his Escort return to the Bloody Tower, where they are stopped by the sentry. Then comes the following dialogue.
SENTRY. Halt! Who goes there?
CHIEF WARDER. The keys.
S. Whose keys?
CR. W. Queen Elizabeth’s keys.
S. Advance, Queen Elizabeth’s keys; all’s well.
Having received permission to go on, the Chief Warder and his Escort walk through the Archway of the Bloody Tower and face the Main Guard of the Tower, who gives the order to present arms, which means to hold a weapon upright in front of the body as a ceremonial greeting to an officer of high rank. The Chief Warder takes off his Tudor-style cap and cries, “God preserve Queen Elizabeth!” “Amen”, answer the Main Guard and the Escort.

New words:
The Yeomen Warders (Beefeaters) – Стражи Тауэра; the Bloody Tower – Кровавая башня; the West Gate – Западные ворота; the Middle Tower – Средняя башня; sentry – часовой; Halt! – Стой! to present arms – взять оружие «на караул»; an officer of high rank – офицер высокого ранга; Amen – Аминь.
