A: Could I ask some friends to join my birthday party on Saturday, Mom?
B: Of course! That sounds like a good idea.
A: Yeah. Could I borrow some money? I need to buy some drinks and snacks.
B: Well, I am going to the market tomorrow. I can buy some drinks and snacks for you.
A: Oh, good. Thank you, Mom.
B: You’re welcome. Oh, could you clean your room?
A: I cleaned it last week.
B: But you need to clean it again for your party.
A: OK, but I need to do my homework first.
B: That’s right. Let’s clean the house after you finish your homework.
A: Sure. What do I need to do?
B: Er, could you sweep the floor and take out the trash?
A: OK. I’ll do them.
