Today afternoon,I played tennis with my foreign friends .They are from india,and study in my school---Wenzhou medical colleage.We communicate in English,because their mother language are English and india.At first ,I can't understand what they said .but as time went by ,I  can fellow a little what they said .At last they told me that thier country is a large South Asian country rich in ethnic diversity,with over one billion people speaking hundreds of languages. Politically it is the world's largest liberal  democracy..when we say goodbey to each other,they shaked my hands and said :u r great!
