大家帮我看看哪里错了!
As we had had a long walk through a market of the Old Delhi.we stopped to have a rest at a square.After a while,we noticed there was a snake-charmer with two large baskets over there,so we went to have a look at him.As soon as he saw us ,he pick up a long pipe inlayed coins and opened one of the baskets.When he began to play a tune,we first saw the snake which rose out of the basket and followed the pipe to move.When snake -charmer suddenly played jazz and pop musics,we were very surpirsed that the nake still moved slowly.It is obvious that the nake couldn't tell the difference betwen Indian music and jazz.
