| If someone asks me, "Do you like music?" I will answer him or her, "Of course, I do."Because I think music is an important part of our lives. Different people have different ideas about music. For me, I like rock music(摇滚乐) because it's so exciting. And my favourite rock band is Foxy Ladies(酷妹). I also like pop music. My classmate Li Lan loves dance music, because she enjoys dancing. My best friend Jane likes jazz music( 爵士乐) .She thinks it is really cool. "I love dance music and rock very much,"says my brother, " because they are interesting." But my mother thinks rock is boring. "I like some relaxing(轻松的) music,"she says. That's why she likes country music, I think. Dear friends, do you like music? What kind of music do you like? | ||||||||||||||||||
