阅读理解。 The karaoke machine is the most annoying invention in Britain,a survey (民意调 查) for the government found.It found that the Japanese invention topped a list of inventions that people wished had never been invented. 2,584 adults were su rveyed in England online.Among them,22 percent chose the karaoke machine.17 percent said 24－hour sports channels,12 percent chose video games,while 11 percent said mobile phones and seven percent said alarm clocks.'Seeing the karaoke machine at the top of that list made me smile,' said Kane Kramer,a director at the British Inventors Society. 'When people are singing karaoke,they are enjoying themselves,but as a member of the audience you are just watching somebody who can't perform for as long as you can bear it. It is antisocial (令人讨厌的)．You might ha ve 10 people who want to sing some karaoke, which means 150 people have to suffer it.But the crazy thing is that people still do go just to be a listener at other people's inability to sing.After a short while-unless they're very drunk they're going to find that listening to performers failing to perform for two hours is not the best way to spend the evening.' Karaoke has turned into a very large industry since being invented in 1971 by Daisuke Inoue,a worker in a club in Japan who was looking to provide music for a customer who wanted to sing on a company trip.
