advertisement plays a big role in our lives. some people don't like to see it everywhere and some people don't care about it. as for me, i think that  advertisement is an inportant part of our world. to keep the economy up we have to sell goods to people but it would be inpossible to sell a lot of products without advertising it. but i believe that it should be limited. i can't stand when i am in museum or theatre or any other cultural place and there i see commercial everywhere around me. i also don't like when i watch an interesting movie and it is interrupteb by a commercial. so my opinion is that the advertisement should have a right to exist but it should be limited.

every nation has its own customs and long-lived traditions. there is a great number of exciting events which are held in every country throughout the year. such events of national importance unite people, make them feel proud of their nation. each family is like a little country with its own traditions. so and my family. we celebrate all holidays in a very special way and it keeps our family together in spirit. our most favorite holiday is christmas. we celebrate it on the 25th of december. preparation for christmas are always pleasant: buying gifts, sending christmas cards and decorating christmas tree with small, bright-colored lights and small colored glass ornaments. our church holds a special service on sunday before christmas.
