Every year, students in many countries learn English. Some of these students are young children. Others are teenagers. Many are adults. Some learn at school, others study by themselves. A few learn English just by hearing the language in films, on television, in the office or among their friends. But not many are lucky enough to do that. Most people must work hard to learn another language.

Many boys and girls learn English at school because it is one of their subjects. They study their own language, mathematics, and English. In England, America, or Australia, many boys and girls study their native language, which is English, mathematics, and another language, perhaps French, or German or Spanish.
