　　Games are fun．After hours of homework it's great to relax by playing a game．But do games ever do kids any harm(害处)?And are there any ways parents can help kids stay away from bad games?The US researchers are trying to find solutions to these problems．

　　They studied what video games could do to children．The researchers found game sellers had made big changes to make sure the games didn’t harm kids．And they suggested that work should be done to find out if video games affected children's school work and health．

　　One problem found was that parents hadn’t taken enough notice of their kids' game-playing habits．

　　“Many game sellers put control(控制键)on the games to help parents make sure that children don’t play games unsuitable for them,”said David Walsh, the president(院长)of the National Institute on Media and the Family．Parents should watch the games kids are playing and know how much time they are spending playing them．

　　The study found that playing games too long could affect kids' health as well as their school work．Almost half of all“heavy garners”were six to seventeen years old．These kids were more likely to have weight and eyesight problems than other kids．Playing too many games also affected how children did at school．

　　Kids are supposed to ask their parents to set a time limit(限制)for playing games and remind them when the time is up．

　　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．
