Music in Our Life I love music, I think people can not live without it. The first thing I do in the morning I switch on my tape — recorder. We can hear music everywhere: in the streets, in the shops, on TV, over the radio, in the cars, in the parks, everywhere. I think it's really doesn't matter what kind of music you prefer: rock, pop, classical, jazz. A lot of people are fond of music. They buy tapes, go to the concerts, visit Concert Halls and Opera Theatres. I enjoy listening music because it reflects my moods and emotions. Very often when I'm blue, I play my favourite merry songs and feel much better. Sometimes I attend music halls and the concerts, when popular groups and singers are there. I like watching music programs on TV. I like to know more and more about popular talented groups and singers I like. One wall of my room is covered with posters of "Bon Jovi", "Scorpions", "Roxette", Russian singers Agutin, Sjutkin, Linda and others. Some people go to musics schools, they play different musical instruments, sing in the chorus, try to compose music. Unfortunately there are so many ungifted singers on the stages, that it makes me sad. To have a good producer doesn't mean to have good ears and voice. I think that only talented people can claim to be singers. 

Музыка в нашей жизниЯ люблю музыку, я думаю, что люди не могут жить без него. Первое, что я делаю утром я переключаюсь на моей ленте - магнитофон. Мы можем слышать музыку повсюду: на улицах, в магазинах, на телевидении, по радио, в автомобилях, в парках, везде. Я думаю, что это на самом деле не имеет значения, какую музыку вы предпочитаете: рок, поп, классика, джаз. Многие люди любят музыку. Они покупают кассеты, идут на концерты, посетить Концертные залы и оперных театров. Мне очень нравится слушать музыку, потому что она отражает мое настроение и эмоции. Очень часто, когда я голубой, я играю мои любимые песни веселые и чувствовать себя намного лучше. Иногда я хожу музыкальные залы и концерты, когда популярные группы и певцы там. Я люблю смотреть музыкальные программы по телевизору. Я хотел бы знать больше и больше о популярных талантливых групп и певцов, которые мне нравятся. Одна стена моей комнаты покрыта плакатами "Bon Jovi", "Scorpions", "Roxette", российские певцы Агутин, Сюткин, Линда и другие. Некоторые люди идут в Musics школы, они играют на различных музыкальных инструментах, поют в хоре, пытаются сочинять музыку. К сожалению, есть так много бездарных певцов на этапах, что это делает меня грустным. Для того, чтобы иметь хороший производитель не значит иметь хороший слух и голос. Я думаю, что только талантливые люди могут претендовать на певцов.
