Reading:

My father came to America from Poland. He used to live in Poland until he was 15. He settled in a small town in Poland. When he moved to the USA, he would never speak English. He didn’t use to learn English at school because he always used to work to help his family’s expenses. After a while, he went to an English course, and then he could understand a bit. But anyway, he used to make a lot of mistakes for some time. Now, he is a fluent English speaker.
