ROBERT BURNS
Robert Burns is the national poet of Scotland. Burns’s poetry is loved and enjoyed by all his countrymen. His father was a small farmer. He was a hardworking man and wanted to give his children the education he could. Thanks to his father Robert got a good knowledge of English, he made a rapid progress in reading and writing; he read and tried to understand Shakespeare, Milton and other writers of the seventeenth-eighteenth centuries. Robert’s father also taught his children arithmetic and other subjects. And at the same time young Robert worked hard on his family farm. When he was 14 he composed his first poem. He traveled much across his native country which he so dearly loved. All this influenced his literary work and resulted in many fine poems. People loved Burns for the generosity and kindness of his nature, for his patriotism and truthfulness. He died at the age of 37.
