n anyone asked me some-thing, I always said "Yes. " But I really didnt know what they were saying. Once I went to a large store to buy a mouse (鼠标) for my computer. When I got there, I was worried about the price. At last I found a cheap mouse. I checked the price to make sure of it before I went to the cashier. While I was at the cashiers, she asked me something. I said, "Yes," even though I didnt under-stand what she said. Then she told me what I had to pay. The price was different. I knew something was wrong. But I was afraid to say anything. Later, at home, I thought about what the cashier said to me. What made the price go up？ Then my husband came home. He looked at the receipt and found out what was wrong. The cashiers question was, "Would you like a one-year warranty(保修)？”and my answer was, "Yes.” Since that day, I have never said "Yes" before I understand the question. And I have never paid more than the actual(实际的)price. The writer is studying in the United States.

l, Dr Browns class finished ten minutes early, so I went to the library between classes. I knew I didnt have much time, but I wanted to get those books on the Industrial Revolution. I looked them up in the card catalogue and went right to the stacks and found them. So I put them in my book bag and headed back toward the door. Then it happened. The exit gate in front of the door wouldnt open, and a guard immediately warned me that I hadnt checked out my books. He thought I was trying to steal them. W: That must have been embarrassing. But why didnt the exit gate open？ M: I asked them that. It seems the books in the library are all magnetically coded, and when you check them out, the librarian behind the desk demagnetises them, then the exit gate will open. W: How interesting!
