Англійська мова дуже важлива, тому що вона стала найбільш уживаною мовою в галузі політики, науки, торгівлі і культурних відносин у світі.
Це також мова великої літератури.
Англійською писали такі письменники, як Вільям Шекспір, Вальтер Скотт, Чарльз Диккенс і Бернард Шоу.
Я одержую велике задоволення, читаючи їхні книги в оригіналі.
Я вивчаю англійську мову в школі.
Також я відвідую курси англійської мови у Москві (курсы английского языка в москве).
Крім того, я читаю англійські книги, журнали і газети.
Я дивлюся відеофільми і слухаю пісні англійською мовою.
У мене є плеєр, тому я часто слухаю пісні чи навчальні касети під час прогулянок чи у метро.
Нові слова я записую на маленькі картки і переглядаю їх щовечора перед сном.
Сподіваюся, що коли-небудь я буду вільно говорити англійською мовою.
My favourite subject is English.
English is very important as it has become the most used language in politics, science, trade and cultural relations in the world.
It is also the language of great literature.
Such writers as William Shakespeare, Walter Scott, Charles Dickens and Bernard Shaw wrote in English.
It gives me great pleasure to read their books in the original.
I learn English at school.
I also attend English courses in Moscow.
I also read English books, magazines and newspapers.
I watch video films and listen to songs in English.
I have a Walkman, so I often listen to songs or teaching cassettes when walking or in the underground.
I write new words on little cards and look them through every evening before going to sleep.
I hope that in the future I’ll speak English fluently!
