Перевести текст (можно по частям) 

To show somebody my achievements, I went to high school to take a course in English for foreigners called "English as a Second Language." There were about 30 students in the classroom. It took almost an hour to get through a process of introducing ourselves. Stefan, Zofia, Marek, Jose, Pedro and Maria.
One at a time they rose from their chairs and stammered something I already knew from my books; an English alphabet, numbers, simple words like: a table, a chair, a boy, a man, a woman. The level of English suggested by the high school didn't seem to fulfill my expectations. I left the course.
After a month or so i tried again, but this time at college. After 15 minutes of introducing ourselves, a doctor of linguistic gave us a lecture about the history of English. Then we were told that it was very important to learn English in a country where English was spoken. It look three hours for the doctor of linguistic to tell us this. Again I left the course.
