A year ago，I paid no attention to English idioms（习语），though my teacher mentioned the importance again and again．But soon，the importance of English idioms was shown in a funny experience．

One day，I happened（碰巧）to meet an Englishman on the road with his friend，and soon we began to talk．As l was talking about how l was studying English，the foreigner seemed to be surprised，gently shaking his head，shrugging（耸一耸）his shoulders，saying，“You don't say!” “You don’t say!” I was puzzled．I thought，perhaps this was not a right topic．So I'd better change the topic．I said to him， “Well，shall we talk about the Great Wall? By the way，have you ever been there?” “Certainly．everyone will laugh at me if I leave China without seeing it．It is fantastic．” He was deep in thought when I began to talk like a tourist guide．“The Great wall is one of the wonders in the world．We are very proud of it．” Soon I was interrupted（打断）again by his order “You don’t say!”．I couldn’t help（忍不住）asking，“Why do you ask me not to talk about it?” “Well，I didn’t ask you to do so，” he answered in surprise．I said，“Didn’t you say ‘You don’t say’?”

Hearing this，the Englishman laughed to tears．He began to explain，“ ‘You don't say!’ actually means ‘really?’．It is an expression of surprise．Perhaps you don't pay attention to English idioms．” I knew I hadn't understood him．Since then I have been more careful with idiomatic expressions．
