Artthere are many different types of arts in the world. the most popular ones are cinema, theater, literature, music and painting. i’d like to tell you a little bit about each of these arts. first of all, my favourite type of art is music. it has always fascinated me how people create such melodic tunes. i love all genres of music, be it jazz, classical, pop, rock, reggae, opera, blues or else. music can change my mood. if i’m sad i try to listen to something cheerful, for example, to disco music. if i want to think in loneliness, i prefer alternative rock. i’m glad that there are so many devices nowadays which allow us to listen to music everywhere we wish. it includes radios, mp-3 players, cd-players, mobile phones. my second favourite type of art is literature. i like reading interesting novels and detective stories. i also value the works of famous writers and poets. speaking of russian writers i’ve read some works of pushkin, lermontov, tolstoy, turgenev, dostoevsky and mayakovski. their works are world-famous and many books have been translated into other languages. theater is gradually becoming an outdated type of art. on the contrary, cinemas become more popular. there are many great theatres and large cinemas in russia. i think people should respect the work of actors and attend theatres more often. as for me, i don’t really like cinemas. if i want to watch a new movie, i buy and watch it at home. painting is another form of art. museums and art galleries have always attracted me. i think that painting is a rather interesting activity. one of my friends is really good at it. he is going to enter the university of arts after graduating from school. his works include oil paintings and pastel. i really admire his talent. i wish i could be as good at painting as him.
