　　Hip hop or rap (说唱 ） music as it is also called,started on the street and in the clubs of the New York City in the 1970s．But today many countries have their own kind of hip hop music．This kind of music comes from reggae, disco and funk music．Rapping means speaking to the rhythm of the music, and it is an important part of the music．People rap to express how they feel about their lives and problems．

　　Would you like to rap in class ? Well actually,hip pop music is played in more than 10,000 schools in the USA．Why ? There is a new school program called “ Flocabulary ”in which teachers use texts and hip hop CDs to help teach different school subjects．The words of the songs are just what students are studying．This makes learning easy and fun．Students and teachers are excited about the positive results it has had on exam marks．One teacher said, “ I've used hip hop songs in class, and I have never seen my students so crazy about history ! You can't imagine how well they imagine how well they remember what I teach ! We even try to write our own songs．”

　　Whose idea was Flocabulary?

　　Blake Harrison, a high school student, was the first person to come up with the idea of Flocabulary．The word “ Flocabulary ” comes from the word “ flow ” and “ vocabulary ”．“ Flow ” is a rap word for “ style ”,or the way a rapper says the words of a song．“ Vocabulary ” means the words you have to learn in a language．How did he get the idea ? Well, he realized he could remember the words of a hip hop song very easily．So,why not make lessons into songs ? Today together with Alex Rappaport, a song writer, Blake produces hip hop songs for maths, science and literature (文学 ）．They are now used in schools with great success．

　　Peter was walking to school from his home with his friend Jim．

　　“I’m thinking．” he said．

　　“What?” Jim laughed．

　　“Before we came to this school, we had studied for 6 years．” Peter said．“And it will be 9 years by the end of this term…”

　　“Don’t you think nine-year studying is too long?” his friend asked．

　　“What about it?Everyone must go to school at least 9 years．Well, we have learned English for years…and you still can’t understand a word of it…．that’s really funny,” Peter shouted when he ran away from his friend．

　　When Jim caught up with him, he said, “I think it is a long time really, when you think about it．”

　　“Mm…．Hey, you haven’t forgotten your math homework this time?”

　　“I did it last night,” Jim answered, when they came to the school gate．“It was difficult, wasn’t it?I sometimes think that all this homework is not good for our brain…We need a rest from all this studying．”

　　“I really can’t agree with you,” Peter said, “studying is good for you; and school isn’t only about studying．We learn lots of other useful things, and at school we can develop our interests．”

　　“You’re right,” Jim agreed．“I wasn’t very interested in playing basketball until I joined the school team．”

　　“So you see, it seems like a long time and a lot of work sometimes, but it helps to make our lives more interesting．”

　　“Now you speak just like my father; you should be a ‘teacher’ at this school, not a student,” Jim joked when the bell rang．
