Rose: Dave, I’m going to pick up food and drink for Saturday’s picnic. Any 61 (suggest)?
Dave: Well, everyone has been talking about 62 (have) a barbecue(烧烤), so 63 not pick up some hamburger meat and hot dogs?
Rose: Okay, but do you know how 64 hamburger meat we are going to need? And hot dogs too?
Dave: Uh, how about three pounds of hamburger and a couple of packages of hot dogs?
Rose: Oh, that's not going to be enough. Do you remember the last picnic we went on? Jim, your roommate, ate about ten hamburgers by 65 (him)!
Dave: Yeah, I remember that. Then seven packages of hot dogs should b enough. And you can pick up some chicken for those who don’t like hamburgers 66 hot dogs.
Rose: Okay. How about five or six bags of potato chips?
Dave: Hmm. It might be 67 (well) to make that eight.
Rose: Okay. Uh, we will need some soft drinks. How about ten of those 2-liter bottles?

Rose: Okay. And what about dessert(甜点)?
Dave: Well, maybe we could ask Kathy 69 (make) a few cherry pies like she did last time.
Rose: Great! I’ll give her 70 call right now.
