     Ireland has had a very difficult history. The problems started in the 16th century when English rulers

fried to conquer (征服) Ireland. For hundreds of years, the Irish people fought against the English. Finally,

in 1921, the British government was forced to give independence to the south of Ireland. The result is that

today there are two "Irelands". Northern Ireland, in the north, is part of the United Kingdom. The republic

of Ireland, in the south, is an independent country.

     In the 1840s the main crop, potatoes was affected by disease and about 750,000 people died of bunger.

This, and a shortage (短缺) of work, forced many people to leave Ireland and live in the USA, the UK,

Australia and Canada. As a result of these problems, the population fell from 8.2 million in 1841 to 6.6

million in 1851.

     For many years, the majority of Irish people earned their living as farmers. Today, many people still work

on the land but more and more people are moving to the cities to work in factories and offices. Life in the

cities is very different from life in the countryside, where things move at a quieter and slower pace.

     The Irish are famous for being warm-hearted and friendly, Oscar Wilde, a famous Irish writer, once said

that the Irish were "the greatest talkers since the Greeks". Since independence, Ireland has revived (复兴) its

own culture of music, language, literature and singing. Different areas have different styles of old Irish song

which are sung without instruments. Other kinds of Irish music use many different instruments such as the

violin, whistles, etc.
