A. It's raining heavily now.
Mum: How's the weather today，Alice?
Alice: It's windy.
Mum: I see. We can go to the supermarket after lunch.
Mum: Look, Alice, They are moving quickly. It's going to rain.
Alice: Oh，Mum. We can't go out now.
Mum: Yes. But we can go after the rain stops.
Alice: That's a good idea.
