根据短文判断下列句子的正确的与错误。

    Have you seen the videos on TV? Do you wear large T-shirts and baggy(宽松的) jeans? Or have you heard someone rap (说唱)? Hip-Hop is very hot now.

Hip-Hop music was started in the middle of the 1970s by African Americans in New York. break-dancing (霹雳舞)and graffiti(涂鸦)are the two main kinds of music in Western Hip-Hop culture. Most of the Hip-Hop songs are about love, jobs or even games.

    Usually in rap, singers speak words very quickly to a certain beat. Most of the words are fun. Singers play off words to make fun of themselves or others. Hip-Hop music has few rules. Singers just do what they think and rap it out in a clever or creative way. The freedom makes a lot of teenagers fall in love with the music. Many of them like wearing large T-shirts and baggy jeans. Famous rap(说唱) and Hip-Hop stars include Eminem in the U. S. and Jay Chou from China.

    Today Hip-Hop is more and more popular across most of the world.
