1. W: Rob， why don’t you come and find me in the library after your history lecture? I’m going there to do my Algebra homework.
M: Oh， I need to check a few things on the reference shelves.
W: I mean， after that we can get some coffee.
M: That’s good.
Q: What is the woman going to do now?
2. M: Laura said you used to be a doctor. I’m really curious why you’re doing this teacher training course！
W: I worked for a doctor for three years， and I just didn’t like it. So I decided to teach biology.
M: My father wanted me to be an accountant， but I’ve always known I wanted to be a dancer.
Q: What was the woman’s first career?
3. W: We’re so unlucky to be in the middle of the bus strike! We’ve spent the first day of our holiday waiting around.
M: There’s probably no point waiting here in the station anymore. Why don’t we go to see if the trains are running?
W: If they aren’t， I just would like to change our tickets and fly home early.
Q: Why are the speakers trapped in the bus station?
4. M: Dr. Smith， what’s it actually like at the South Pole? I know you’ve been there several times.
W: Yes， I have， and each time I’m struck by the unusual beauty of the place. It’s magnificent， but you can only visit it in the summer months.
M: You mean November to March?
W: Yes， because it’s completely dark for four months of the year. And in addition， it’s the coldest place on earth.
M: Colder than the North Pole? Why’s that?
W: Antarctica is a land mass shaped like a dome， with the result that the winds blow down the slopes at speeds of up to 150 km an hour and that’s what makes it so cold.
Q: Why is Antarctica so cold according to Dr. Smith?
5. W: Mrs. Harwick always looks so severe! I could imagine her working as a manager of a museum， alone in some dark dusty room， but she seems such a strange personality to be teaching kids!
M: Have you seen her at work， though? She’s actually very nice and kind! All kids behave well and like her when she speaks to them.
Q: What proverb can we infer from the conversation?
