Part B
Questions 31-34 Listen to a conversation between two students.
Hey, Karen. Looks like you got some sun this weekend.
Yeah, I guess so. I spent the weekend at the beach.
Oh, yeah? That’s great! Where did you stay?

Some friends of my parents live out there. And they invited me for as long as I wanted to stay.
So, what are you doing back here already?
Oh, I have a paper I need to work on. And I just couldn’t do any serious studying at the beach.
I don’t blame it. So, what did you do out there? I mean, besides lie out in the sun, obviously.
I jogged up and down the beach and I played some volleyball. You know, I never realize how hard it is to run on sand. I couldn’t even get through a whole game before I had to sit down. It’s much easier to run on the wet sand near the water.
Not to mention cooler. Did you go swimming?
I wanted to, but they said the water isn’t warm enough for that until a couple of months from now. So I just wetted in up to my knees.
It all sounds so relaxing. I wish I could get away to the beach like that.
It looks like you could use it. Don’t tell me you spent the weekend in the library again.
31. How did the woman spend last weekend?
32. Why did the woman come home so soon?
33. Why did the woman have to stop playing in the volleyball game?
34. Why didn’t the woman go swimming?

Questions 35-38 Listen to a conversation between a graduate student and her biology professor.
Thanks for stopping by, Ann. I’d like to talk to you about a research project that I thought you might be interested in. A friend of mine is working in Yellow Stone National Park this summer.
Yellow Stone! I’ve always wanted to spend sometime out Wyoming.
Wait till you hear what the project is. She’s working with the buffalo population.
The herds have been increasing in size latterly which is good in theory.
Yeah. But I though they were in endanger of becoming extinct.
Well, apparently, because of all the winter tourists, paths are created in the snow.
More buffalo survived in the harsh winters because the paths made it easier for the buffalo to move around and find food. But it turns out that some of the herds are infected with the bacteria.
Oh, yeah. I heard about that. A blue…
A blue seller aborders.
Right. It’s been around for quite a while.
Yes, it has. And because the buffalo population is increasing, they’ve been roaming more than usual. And the disease’s begun to spread to the cattle ranches that border the park.
That’s bad news. Isn’t that the disease that causes animal to abort their young?
Yes. And it’s caused a lot of controversy. Some of the ranchers even want to destroyed the buffalo herds.
That’s awful! Have they made much progress with the research?
So far, they’ve been collecting tissue samples from dead buffalo to see if the bacteria is present.
I’ll really be interested in working on this. You know I’ve been researching diseased animal population.
That’s why I thought of you. I took the liberty of mentioning your name to my friend.
She’s hoping you’ll be able to spend the whole summer out there.
Well, I was going to work on my thesis a lot in July. But I’m sure my adviser wouldn’t want me to pass up this opportunity.
35. What did the professor want to talk to Ann about?
36. According to the professor, why is the buffalo population increasing?
37. Why does the professor think Ann would be interested in going to Yellow Stone?
38. How will Ann probably spend the summer?

Part C
Questions 39-41 Listen to a talk given by a tour guide.
Welcome to Everglade’s National Park. The Everglade is a watery plain covered with saw grass that’s the home to numerous species of plants and wild life. And one and half million acre is too big to see it all today. But this tour will offer you a good sampling. Our tour bus will stop first at Tailor Slue. This is a good place to start because it’s home to many of the plants and animals typically associated with the everglade. You’ll see many exotic birds and of course a world famous alligators. Don’t worry. There’s a boardwalk that goes across the marsh, so you can look down at the animals in the water from a safe distance. The boardwalk is high enough to give you a great view of the saw
grass prairie. From there we’ll head at some other marshy and even jungle-like areas that feature wonderful tropical plant life. For those of you who’d like a close view of the saw grass prairie, you might consider running a canoe sometime during your visit here. However, don’t do this unless you have a very good sense of direction and can negotiate your way through tall grass. We hate to have to come looking for you. You have a good fortune of being here in the winter, the best time of the year to visit. During the spring and summer the mosquitoes will just about to eat you alive. Right now, they are not so bothersome, but you’ll soon want to use an insect repellent.
39. What is the main purpose of the tour?
40. What does the speaker imply about pedaling across the water in a canoe?
41. Why is it good to visit the everglades in the winter?

Questions 42-46 Listen to a talk given by an astronaut.
Thank you. It’s great to see so many of you interested in this series on survival in outer space. Please excuse the cameras. We are being radio taped for the local TV stations. Tonight I’m going to talk about the most basic aspect of survival—the space suit. When most of you imagine an astronaut, that’s probably the first thing that comes to mind, right? Well, without space suits, it would not be possible for us to survive in space. For example, outer space is a vacuum. There’s not gravity or air pressure. Without protection, a body would explode. What’s more, we’d cook in the sun or freeze in the shade with temperature’s ranging from a toasty 300 degrees above to a cool 300 degrees
below zero Fahrenheit. The space suit that NASA has developed is truly a marvel. This photo enlargement here is a left side’s image of an actual space suit worn by astronauts on the last space shuttle mission. This part is the torso. It’s made of seven extremely durable layers. This thick insulation protects against temperature extremes and radiation. Next is what they call a bladder of oxygen. That’s inflatable sack filled with oxygen to simulate atmospheric pressure. This bladder presses against the body with the same force as the earth atmospheric sea level. The innermost layers provide liquid cooling and ventilation. Despite all the layers, the suit is flexible allowing free movement, so we can walk. Another really sophisticated part of the space suit is the helmet. I brought one along to show you. Can I have a volunteer come and demonstrate?
42. What is the speaker’s main purpose?
43. What will cause an unprotected human body to explode in outer space?
44. Where is the bladder of oxygen located?
45. What does the speaker show the audience as she describes the main part of the space suit?
46. What will probably happen next?

Questions 47-50 Listen to a talk about a program sponsored by a student organization.
Good evening. My name is Pam Jones and on behalf of the modern dance club, I’d
like to welcome you to tonight’s program. The club is pleased to present the TV version of the Catherine Wheel, Twyla Tharp’s rock ballet. This video version of the ballet has been even more successful with audiences than the original theater production. It includes some animation, slow motion and stop action phrases that really help the audience understand the dance. The title of the piece refers to Saint Catherine, who died on a Wheel in 307 AD. Nowadays, a Catherine wheal is also a kind of firework that looks something like a pinwheel. Any way, the dance is certainly full of fireworks. You’ll see how Twyla Tharp explores one family’s attempt to confront the violence in modern life. The central symbol of the work is a pineapple. But exactly what it represents has always created a lot of controversy. As you watch, see if you can figure it out.
The music for this piece is full of the rhythmic energy of rock music. It was composed by David Burn of the rock band Talking Heads. And the lead dancer in this version was Sara Radnor who is perfectly suited to Tharp’s adventurous choreography. Following the video, dance teacher Mary Parker will lead the discussion about the symbolism Mr. Tharp used. We hope you can stay for that. So, enjoy tonight’s video and thank you for your support.
47. What is the purpose of the talk?
48. Why was the video version of the dance more successful than the theater production?
49. What kind of music is the dance performed to?
50. What will probably be included in the discussion after the program?
