I have different subjects at school. Some of them are easy and some are difficult. My favourite subject is English. It is not easy but it is interesting. Every lesson we learn to pronounce English words correctly, read  English literature, use  tape recorder for listening of English texts, play different games. My favourite exercise is a role-game. When we talk to each other as in a  real life, f.e, a conversation in a shop, or in a school canteen. Next year I will attend English couses after my lessons. I like English and I want to learn it better.

People work in different jobs. They live in cities, in towns and on farms. They work in the mountains, in the fields, in factories and offices and on the roads. Many people live near the sea and earn their living from it.
