dear Ann,
thank you for your letter. you asked me to tell you why you should learn English, so I'm gonna answer you.
English is very useful language in the world, lot of people speak in English. being in every place you can use English and people can understand you as minimum 80%.
you can study English in school, but if you can't, you can take a lessons of English. if you need more or you don't have money for it or you want to learn it easy so you can watch any films or cartoons with English subtitles or in English language as well.
i hope it helped you!
good luck, (ваше имя)
