Karaoke

Karaoke is a welcome and popular source of entertainment. People all over the world are familiar with it. It enjoys popularity in get together （聚會） and evening gala（聯歡晚會）。 Common folks （平民百姓） can simply sit in the living room and sing songs that best suit their tastes. Thus it enriches people's lives in a simple but creative way.

　　Being an inexpensive and convenient source of entertainment， Karaoke is of various functions. Firstly， it enlarges our social circle and strengthens our bond （紐帶）。 Secondly， Karaoke can remove the ban of social walls between people. Thirdly， it helps channel enthusiasm （熱愛） into enjoyable and instructive pastimes （消遣）。 The list does not stop here.

　　However， it can also be a nuisance. For instance， some fans sing loudly late at night， which disturbs others. For another instance， some suffer from a sore throat from excessive practice. Karaoke， in the final analysis， should be for the overall improvement of social civilization. Its enduring appeal should lie in the high quality of entertainment， not noise pollution.
