Pinyin practice (1)

I always choose some useful  tongue twisters(rao4 kou3 ling4) to help my students practice their pinyin, here is one of them(this is for you to practise your tones):

        Māma lā mǎ，Mǎ màn māma mà mǎ。
         妈妈   拉 马，马   慢      妈妈  骂  马。
         Mom was pulling a horse, the horse moved slowly, so mom shouts  at the horse.
