听力原文：W: Did you have a good time last weekend？

M: Yes, I did. I visited some friends in Pennsylvania. They live in a small town called Canonsburg.

W: That must have been interesting. I've never been in a small town——just big cities.

M: Neither had I.

W: What did you do？

M: There isn't as much to do as there is here. No plays or concerts, that is, people make their own entertainment, though.

W: What do you mean？

M: Well, Saturday we went to a potluck supper.

W: A potluck supper？ What's that？

M: The whole neighborhood has a party. Everybody brings something. It's all put on the table and you can eat whatever you like. That is a potluck supper.

W: It's something like a picnic, isn't it？

M: Well, yes. The weather was warm, so we had this one outdoors. But in winter they have them indoors too.

W: What else did you do？

M: Sunday we went for a drive. We had lunch at a drive-in.

W: Is the countryside interesting？

M: Beautiful farmland. You'd like it.

W: I'm sure I would.

M: Sunday evening some people came to dinner. It was very informal we just sat around and talked. Just a nice Sunday night supper.

W: That's the kind of evening I like. I don't care for a formal dinner so much.

M: Neither do I.

听力原文：Now, we are going to examine the weather forecast for the coming week. We expect

听力原文： Now, we are going to examine the weather forecast for the coming week. We expect a minor heat wave to sweep across the nation with temperatures hitting as high as 35 degrees Celsius in some parts of the country, especially in the Mid-west. Tomorrow, we should see temperatures rise sharply to 29 degrees Celsius and then steadily increase to peak on Thursday and Friday of 35 degrees Celsius. They will then taper off by the weekend to 30 degrees Celsius. Currently, we have slightly above normal temperatures for this time of year, coasting at around 25 degree Celsius. Therefore, remember to try and stay indoors if possible, especially if you have any children or elderly under your care. And don't forget to drink plenty of water. It's going to be a tough week ahead of us. Now, back to the news desk, and I'll see you again tomorrow.

What type of weather should the listeners expect？

A．Warm. .

B．Hot.

C．Rainy.

D．Foggy.
