F: OK, I think we have 2 choices of where we can spend our vacation. The first place is a little house. It's located on a fruit farm. But it says there is no air conditioner. ,M: That's OK. It's on the rainy side of the island. It's cooler there. ,F: You're probably right. But there is no washing machine or dryer, not even a TV. ,M: Oh no, no TV? That's terrible. What's our second choice? ,F: It's on the opposite side of the island, a very nice place with a big swimming pool. It's only 3 blocks from the ocean and the pool area also has a beautiful garden. ,M: Wow, it does have everything, washing machine, dryer, TV, refrigerator. All we need is our toothbrushes. Let's go with the second choice. I can't wait to go.
(A) F: I'm sorry, I didn't catch that. Would you mind speaking more slowly? (B) F: Yeah, it does have everything, washing machine, dryer, TV, and refrigerator. And it has a big swimming pool! (C) F: Really? You mean we don't need our toothbrushes because the second place provides toothbrushes? (D) F: Well, although it doesn't have washing machine, dryer, TV, or refrigerator, it has a big swimming pool!

F: Next week is your birthday party. How exciting! What do you want for your birthday? ,M: Well, a car like yours would be fantastic. ,F: Hmm...Maybe not a car just yet. You're only turning 9, you know? How about a doll? ,M: Mom, I'm a boy. Boys don't play with stupid dolls, but a machine gun would be OK, too. ,F: Well, not this time. Maybe we could get you a nice dress and a little purse, son. Maybe... ,M: Maybe I should change my name to Mary since you seem to want a daughter so badly?
(A) F: I believe you'll love the doll for your birthday next month, my daughter. (B) F: You know I was only joking, son. You'll turn 18, a grown-up, tomorrow. (C) F: It's just a joke for my little son. Come on, I'll buy you a toy car next week. (D) F: I am afraid I did not quite catch what you were saying. Please repeat it.
