Do the preparation task first. Then watch the video and do the exercises.
And now, a page from our Sunday morning Almanac. February 6th, 1952. Seventy years ago today. The day Princess Elizabeth, Duchess of Edinburgh, became Queen Elizabeth II. Her ascent was sudden.
TV voice: Nairobi, Kenya's capital was in a sunny mood for the visit of Princess Elizabeth and the Duke of Edinburgh.
The Princess was in Kenya on what was supposed to be a five-month overseas tour, when her father, King George VI, died. Word of his death first reached Elizabeth's husband, Philip, who told his wife the news that would change their lives forever.
TV voice: And the new queen left immediately for London, where her uncle, the Duke of Gloucester, and Earl Mountbatten, uncle of the Duke of Edinburgh, were waiting to welcome the girl who left as a royal ambassador and returned as a queen.
The ensuing seven decades of the Queen's reign brought periods of national prosperity and political upheaval, as well as the decline of the once vast British Empire.
Prince Philip died last April, but, 70 years on, the woman who ascended to the throne at age 25 occupies it still.
In June, Britain will stage a Platinum Jubilee celebration to honour a monarch who, in a world of constant change, remains a singular figure of strength and continuity.
