The royal family is a part of British history and cultural identity.

Up until the 17th century, people believed that the British king or queen had a “divine(天赐的)right” to rule. This was the idea that God chose the king or queen and that he or she was therefore above the law. However, this idea was challenged during the English Civil War, when King Charles the First was put in prison and then killed in 1649.

So what role does the British royal family have today?

The Queen is head of the UK and the Commonwealth. She has important formal duties that go with her different titles. As Head of State, for example, she represents the UK on visits abroad and invites other world leaders to visit the UK;as Head of the Armed Forces in name, only she can declare when the UK is at war or when a war is over. She has to sign many government and Commonwealth documents every day.

Although the royal family does the work for the UK, there are British people called“anti-monarchists(反君主制者)”who do not believe there should be a royal family. One criticism(批评意见)is that the British people should not have to pay for the royal family with their taxes(税).

Today, the royal family works hard to be relevant(相关的)in the modern world. The Queen still gives a speech to the nation on television at Christmas, but it gets less and less formal every year;now it is even available as a podcast(播客).

In 2005, after graduating from university, Prince William spent time teaching English in Uruguay, the sort of work many ordinary young British people do in their gap years.
