Talks and Conversations
Directions: In this part of the test, you will hear several short talks and conversations. After each of these, you will hear a few questions. Listen carefully because you will hear the talk or conversation and questions ONLY ONCE, when you hear a question, read the four answer choices and choose the best answer to that question. Then write the letter of the answer you have chosen in the corresponding space in your ANSWER BOOKLET.
听力原文: M: Happy Anniversary!
W: Oh, thank you. The flowers are beautiful. You shouldn't have… especially since our anniversary was last week.
M: What? Oh, I completely forgot...
W: Again?
M: No way. I can't believe it.
W: Neither can I, but you did.
M: Ah, how can I make it up to you… again? Anything!
W: Okay, let's negotiate. First of all, I want to go on that dream vacation you've always promised me.
M: You mean, to Chicago?
W: No! To Europe. I want to fly first class and stay at 5-star hotels. And no more places with broken heaters, leaky showers, and dirty bedding.
M: Ah, were those places that bad?
W: Well, SOMETHING a little nicer, and, oh yeah. Next, I want to get a new kitchen stove. The old one took its last breath weeks ago.
M: But we…
W: No, we're NOT going to use the outdoor barbecue anymore. It isn't any fun at all cooking outside in the winter, with icicles hanging from your nose.
M: That bad?
W: Not for YOU since you're always watching from inside.
M: Oh, well.
W: And finally, I want a new wardrobe: some new dresses, shirts, pants, earrings...
M: But…
W: And, NO, I'm not going to wear your grandmother's old secondhand pants again.
M: Is that it?
W: Uh, hmm, for now. So, why don’t we grab a bite to eat before we start planning the entire adventure.
M: Ok, I am a bit hungry now.
W: These steaks are really delicious. Well, let's see. Paris, Rome, London, then a short detour to Russia, China, and, ooh, and Hawaii on the way home.
M: Wow. I'd better ask the boss for a huge raise.
