I want a cross talk about Christmas.

A Have you all been to school? B I did study for a few years. How many years? B four years. A is better than me. How many years did you go to school? Two years. B If you study hard for two years, that's fine. A says two years is not enough. Why isn't b two years? I have been ill for several days. How many days has B been ill? One year and eleven months. B only studied for a month. Wow! A also skipped class for 29 days. Just one day! It was Sunday. Wow! I haven't studied all day! This is a joke. After studying for a few days, I am better at arithmetic. B you can't. You can't compete with me in arithmetic. I am best at arithmetic. Oh, are you good at arithmetic? B ok! I have learned addition, subtraction, multiplication and division, and I know decimal points and fractions. A Well, I'll give you a question. Do you count? B yes. What is one plus one? One plus one equals two! This is addition. A: Yes! What's the difference between one and one? One minus one ... that's all. A what? You think that one must be subtracted from the other. Isn't that gone? A is wrong. One minus one equals two! How can b be equal to two? Hey! I don't understand. Let us take a fan as an example. There's already one here. Do you want to pick up (subtract) another one? Isn't that two? B Oh, where can I pick up the car? Answer! B: Good! I chop and he chops (picks up). A You didn't work it out anyway. B, you ask another question. A vertical, how much is a circle here? B equals ten. A well, add another circle? B one hundred. One more lap. B 1000。 Draw another circle? B ten thousand. A line. If you put this vertical line across these four circles, how much is it? B Well ... I don't know. A sugar-coated gourd! B sugar gourd! !
