I know that you are all learning English. Do you find it difficult?

No, not really. I think language learning is fun. I can learn it fast.

I find it rather difficult. Especially grammar. My teacher says I make a lot of grammar mistakes. In fact I prefer reading.

And what about you, Boris?

I liked learning English at the beginning but now it`s getting more difficult and less fun. There are so many things to remember – words, grammar, spelling pronunciation. English has such a rich vocabulary. I don`t always understand my teacher.

I see. And what do you do to learn English successfully? Have you got any special rules that you follow?

I try to do my homework regularly. It helps me to practice English when there are no classes. I know that practice means perfect. I also watch films in English and listen to tapes.

I listen to English songs. Eminem is my favourite singer. English songs help me to understand English better. I have learned some of them and sing them with my friends.

I do a lot of exercises, watch American video films in English and read adapted books. That`s what I like most of all.

And may I ask you how you are planning to use English in the future?

I`d like to learn to speak English well because I want to visit many countries of the world and meet different people. I hope I will be able to speak English to them.

I`d like to be a computer programmer and I`ll need English for my future job. A lot of modern computer programmes are in English.

I don`t know how I am going to use my English yet. I just like learning it. Maybe I`ll learn another language – French, Spanish or Italian. Maybe I`ll become a linguist. I can`t wait to grow and go to university.
