短对话：
11. W: I forgot to tell you that Fred called last night to borrow your sleeping bag.
M: Oh, I saw him at the gym this morning, but he didn’t say anything. So he must have asked somebody else.
Q: What does the man imply?
12. W: These summer days are getting to be more than I can take. It was even too hot to go to the pool yesterday.
M: Hang in there. According to the weather report we should have some relief by the end of the week.
Q: What does the man mean?
13. W: Well, tonight we have Professor Brown in our studio to talk about the famous oil painting of Queen Victoria. Good evening, professor.
M: Good evening, madam, my pleasure to be here tonight.
Q: What is the woman doing?
14. M: The plants next to the window always look brown. You wouldn’t know by looking at them that I water them every week.
W: Maybe they don’t like direct sunlight. I had the same problem with some of my plants. And a little shade helps them immensely.
