input: Please answer the following: W: Hi, Jack. It's me, Ann. I wasn't at school today. Have we got any homework to do for tomorrow?  M: Let me see. Well, we've got to do the math problems on Page 40 in our textbook.  W: All right. I've got it.  M: Then, we have to go on with our reading for English. The history teacher wants us to read the chapter on the History of London for tomorrow, and write down the most important dates and events in that chapter.  W: Anything else? Ah...ah, music?  M: No, we haven't any music homework, but the science teacher is giving us a test on Friday, so we have to study for that.  W: Oh no. I'm so bad at science. I hate it. Thanks, Jack.  M: Don't mention it. See you tomorrow.  What was said before this conversation?

Answer: M: My mother is a teacher. She teaches English in our school. What about your mother, Ann?
Problem: Terry: Yes.  Frank: It must be an exciting trip.  Terry: Well, I've really seen lots of things. I saw the most spectacular view when I was crossing a bridge to Manhattan at dusk, and the skyscrapers were lit up producing a classic nighttime view of Manhattan.  Frank: That's really beautiful.  Terry: But that's not the whole picture. Some of the streets in New York are very rough. I saw large piles of garbage cans at the roadside, and graffiti all over garage doors and store shutters.  Frank: I can't believe it.  Terry: The garbage are tidily bagged and boxed, though.  Frank: Did you stay in a hotel?  Terry: Yes. The hotel we stayed at turned out to be fairly decent, though the room was small, with a tiny bathroom that was only about 3 feet larger than the bed. As I was inexperienced with tourist-area hotels, I was startled, I mean, the room was $129 a night. But at least the room was clean and the bed reasonably comfortable.  Frank: What's your general impression of New York?  Terry: Well, restaurants pack their tiny tables very tightly; grocery stores and bookstores have aisles that are narrow; the sidewalks are cluttered with newsstands, vendors and their carts, and places that aren't restrictively small, such as the lawns around the Natural History Museum, are full of people, so they're no escape.

A: Frank: Hi, Terry, you're just back from New York.
Problem: Given the question: M: It would be better if you could check the same information in English newspapers afterwards.  What was said before this conversation?

W: In my opinion, watching the news on TV is a good way to learn English. What do you think?
input question: M: The Public Library? But there are so many public libraries in London. Which one do you want to go to?  W: The nearest one.  M: That's rather far away, too. You'd better take a bus. Take the No. 7 bus to the zoo, then change to the No. 9 bus and get off at the end.  W: And where's the No. 7 bus-stop, please?  M: Go straight down the street, and turn left at the traffic lights. Then take the second turning on the right, and you'll find the bus-stop near the corner. You can't miss it.  W: Thank you very much.  M: Not at all.  What was said before this conversation????
output answer: W: Excuse me. Can you tell me the way to the Public Library?
input question: M: Not too good.  W: Well, the term exam is always more difficult. Work harder, and you'll certainly do better next time.  M: I've worked hard enough, I think, but unluckily, I have never done well in the exam.  W: Well, it's no use worrying about the exam now. Let's talk about the football game tonight. It's much more interesting.  M: Is there a football game on TV tonight?  W: Yes it's between the Chinese team and the Japanese team.  M: ... Er I'd rather watch some other programmes.  W: Why? You're so interested in football.  M: The Chinese team has always played badly in the important match, just as I have done in the important exam.  What was said before this conversation????
