A year ago, I paid no attention to English idioms（习语）, though my teacher told us the importance again and again. But soon, the importance of English idioms was shown in an amusing experience.
One day, I happened to meet an Englishman on the road, and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be surprised. Gently shaking his head，shrugging his shoulders, he said，“You don’t say!” “You don’t say!” I was puzzled. I thought, perhaps this is not a right topic. “Well, I’d better change the topic.” So I said to him. “Well, shall we talk about the Great Wall? By the way, have you ever been there?” “Certainly, everyone back home will laugh at me if I leave China without seeing it. It was wonderful.” 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 words: “You don’t say!” I couldn’t help asking, “Why do you ask me not to talk about it?” “Well, I didn’t ask you to do so,” he answered, greatly surprised. 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 realized I had made a fool of myself. Since then I have been more careful with idiomatic expressions. Remember: what the English teachers said is always right to us students.
【小题1】A year ago, I paid no attention to English idioms because       .

The Great Wall is known ____ the world.

One day, I happened to meet an Englishman in the street and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be very surprised, gently shaking his head and saying “You don’t say!”
I was confused, and I thought, “Perhaps this is not a right thing to talk about.” Then I said to him, “Well, shall we talk about the Great Wall? Have you ever visited it?”
“Certainly! Everyone back home will laugh at me if I leave here without seeing it. The Great Wall is wonderful! ” “Yes, it is one of the wonders in the world. And people of many countries have come to visit it.” As I went on telling him more about it, he stopped me again, “You don’t say!”
I couldn’t help asking, “Why couldn’t I talk about it?”
“Well, I didn’t stop you talking about it,” he answered, greatly surprised.
“Didn’t you say ‘You don’t say!’?” I asked again.
Hearing this, the foreigner laughed loudly. He began to explain, “’You don’t say!’ means ‘Really’. Perhaps you know little about English idioms(习惯用语).”
Wow! How foolish I was! Since then I have been careful with English idioms.
