(2013·安徽卷)Argentina in the late nineteenth century was an exciting place.Around 1870，it was experiencing an economic(经济的)boom，and the capital，Buenos Aires，attracted many people.Farmers，as well as a flood of foreigners from Spain and Italy，came to Buenos Aires seeking jobs.These jobs didn't pay well，and the people felt lonely and disappointed with their new life in the city.As the unhappy newcomers mixed together in the poor parts of the city，the dance known as the tango(探戈舞)came into being.
At the beginning the tango was a dance of the lower classes.It was danced in the bars and streets.At that time there were many fewer women than men，so if a man didn't want to be left out，his only choice was to dance with another man so that he could attract the attention of the few available women.Gradually，the dance spread into the upper classes of Argentinean society and became more respectable.
