M: What's this, Sally?
W: It's my homework, sir.
M: You haven't handed in your homework yet?
W: No, I haven't. I'm sorry.
M: Well, what's your excuse then? What has happened, Sally?
W: My mother was ill and I had to stay at home.
M: Oh, I see.
W: It's true, sir. I've brought a note. Here it is.
M: That's all right. But do your homework on time this week.
W: Yes, sir.
M: Someone named Cooper phoned this afternoon. He left word for you to call him. He's at the Biltmore Hotel. You can get in touch with him there.
W: That's my old friend, Dave Cooper. I knew he was coming to town.
M: Shall we ask him to our party tonight?
W: I'd like to. But we've already invited twenty people. And the house is not so big.
M: Don't worry. We can always make room for one more.
W: That's true. And the other friends will like Dave. He's very friendly.
M: Be sure to tell him not to dress up. It's not an important party, you know.
W: OK. I'll go get Dave in the car. He doesn't know this city. He might lose his way coming alone.
Now boys and girls, let's begin our class. As I know, you are interested in some strange math problems. So today I'm going to tell you one of the strangest ways to multiply numbers of two or more figures. Maybe you don't know the word "multiply". The word "multiply" means "乘……, 乘法的乘" in Chinese. For example, 8 multiplied by 2 is 16. It means "8乘以2是16" in Chinese. Do you understand now? Of course, there are many ways to multiply numbers. But here is one of the strangest.
Imagine you wish to multiply 23 by 17. In Chinese, it means 23 乘以 17. Half of 23 is 11.5. Write only 11 under 23 as you see in the paper. Half of 11 is 5.5. Write only 5 under 11. Now think it over, what number will you write under 5? Yes, you are right, just 2. Now please write the number under 5. Continue until you have 1.
Now write numbers under 17. But this time you must multiply each number by two to write the number under it. For example, you should write 34 under 17. As a rule, what number will you write under 34? Yes, you are right, 68. Now please write the number under 34. Continue until you have a number on the same line as 1. Now draw a line through any row that has an even number on the left. Yes, even number means 偶数 in Chinese. In our example there is only one even number. Right? Now please draw a line through the line that has an even number on the left. Now add the rest of the numbers in the right-hand row. Believe it or not, you will get the right answer. What is it? OK. Please write the number, I mean the right answer in the right place.
Now class, I'll give you several minutes to discuss how it works.

One possible version:
Recently I have had a discussion about the ways to learn English better with Allen, a student from Britain. In his opinion, the best ways are reading English newspapers and talking with friends. He also believes that sometimes seeing English films isn't a bad way.
I quite agree with him. However, I think, we can go surfing online, where we can find a lot of information in English to read. Besides, we can look for an e-pal from an English-speaking country so that we can get to know something about his or her country. Finally, learning English grammar well is also a great help.
