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?

Question 1-8

With Robert Laurent and William Zorach, direct carving
enters into the story of modern sculpture in the United States.
Direct carving - in which the sculptors themselves carve stone
or wood with mallet and chisel - must be recognized as some
-thing more than just a technique. Implicit in it is an aesthetic
principle as well: that the medium has certain qualities of beauty
and expressiveness with which sculptors must bring their
own aesthetic sensibilities into harmony. For example, some-
times the shape or veining in a piece of stone or wood suggests,
perhaps even dictates, not only the ultimate form, but
even the subject matter.

The technique of direct carving was a break with the nineteenth-
century tradition in which the making of a clay model
was considered the creative act and the work was then turned
over to studio assistants to be cast in plaster or bronze or carved
in marble. Neoclassical sculptors seldom held a mallet or chisel
in their own hands, readily conceding that the assistants they
employed were far better than they were at carving the finished
marble.
With the turn-of-the-century Crafts movement and the
discovery of nontraditional sources of inspiration, such as
wooden African figures and masks, there arose a new urge for
hands-on, personal execution of art and an interaction with the
medium. Even as early as the 1880's and 1890's, nonconformist
European artists were attempting direct carving. By
the second decade of the twentieth century, Americans -
Laurent and Zorach most notably - had adopted it as their primary
means of working.

Born in France, Robert Laurent(1890-1970) was a prodigy
who received his education in the United States. In 1905
he was sent to Paris as an apprentice to an art dealer, and in
the years that followed he witnessed the birth of Cubism,
discovered primitive art, and learned the techniques of wood-
carving from a frame maker.

Back in New York City by 1910, Laurent began carving
pieces such as The Priestess, which reveals his fascination with
African, pre-Columbian, and South Pacific art. Taking a walnut
plank, the sculptor carved the expressive, stylized design.
It is one of the earliest examples of direct carving in American
sculpture. The plank's form dictated the rigidly frontal view
and the low relief. Even its irregular shape must have appealed
to Laurent as a break with a long-standing tradition that
required a sculptor to work within a perfect rectangle or square.

Question 9-19

Birds that feed in flocks commonly retire together into
roosts. The reasons for roosting communally are not always
obvious, but there are some likely benefits. In winter especially,
it is important for birds to keep warm at night and conserve
precious food reserves. One way to do this is to find a
sheltered roost. Solitary roosters shelter in dense vegetation or
enter a cavity - horned larks dig holes in the ground and
ptarmigan burrow into snow banks - but the effect of sheltering
is magnified by several birds huddling together in the
roosts, as wrens, swifts, brown creepers, bluebirds, and anis
do. Body contact reduces the surface area exposed to the cold
air, so the birds keep each other warm. Two kinglets huddling
together were found to reduce their heat losses by a quarter
and three together saved a third of their heat.

The second possible benefit of communal roosts is that
they act as "information centers." During the day, parties of
birds will have spread out to forage over a very large area.
When they return in the evening some will have fed well, but
others may have found little to eat. Some investigators have
observed that when the birds set out again next morning,
those birds that did not feed well on the previous day appear to
follow those that did. The behavior of common and lesser
kestrels may illustrate different feeding behaviors of similar
birds with different roosting habits. The common kestrel
hunts vertebrate animals in a small, familiar hunting ground,
whereas the very similar lesser kestrel feeds on insects overa
large area. The common kestrel roosts and hunts alone, but
the lesser kestrel roosts and hunts in flocks, possibly so one
bird can learn from others where to find insect swarms.
Finally, there is safety in numbers at communal roosts
since there will always be a few birds awake at any given
moment to give the alarm. But this increased protection is partially
counteracted by the fact that mass roosts attract predators and
are especially vulnerable if they are on the ground. Even those
in trees can be attacked by birds of prey. The birds on the
edge are at greatest risk since predators find it easier to catch
small birds perching at the margins of the roost.

Question 20-30

Before the mid-nineteenth century, people in the United
States ate most foods only in season. Drying, smoking, and
salting could preserve meat for a short time, but the availability
of fresh meat, like that of fresh milk, was very limited;
there was no way to prevent spoilage. But in 1810 a French
inventor named Nicolas Appert developed the cooking-and-sealing
process of canning. And in the 1850's an American
named Gail Borden developed a means of condensing and preserving
milk. Canned goods and condensed milk became more
common during the 1860's, but supplies remained low because
cans had to be made by hand. By 1880, however, inventors
had fashioned stamping and soldering machines that mass-produced
cans from tinplate. Suddenly all kinds of food could be
preserved and bought at all times of the year.

Other trends and inventions had also helped make it possible
for Americans to vary their daily diets. Growing urban
populations created demand that encouraged fruit and vegetable
farmers to raise more produce. Railroad refrigerator cars
enabled growers and meat packers to ship perishables great
distances and to preserve them for longer periods. Thus, by the
1890's, northern city dwellers could enjoy southern and
western strawberries, grapes, and tomatoes, previously available
for a month at most, for up to six months of the year. In
addition, increased use of iceboxes enabled families to store
perishables. An easy means of producing ice commercially had
been invented I the 1870's, and by 1900 the nation had
more than two thousand commercial ice plants, most of which
made home deliveries. The icebox became a fixture in most
homes and remained so until the mechanized refrigerator
replaced it in the 1920's and 1930's.

Almost everyone now had a more diversified diet. Some
people continued to eat mainly foods that were heavy in starches
or carbohydrates, and not everyone could afford meat. Never-
theless, many families could take advantage of previously
unavailable fruits, vegetables, and dairy products to achieve
more varied fare.

Question 31-38

The ability of falling cats to right themselves in midair
and land on their feet has been a source of wonder for ages.
Biologists long regarded it as an example of adaptation by
natural selection, but for physicists it bordered on the miraculous.
Newton's laws of motion assume that the total amount of spin
of a body cannot change unless an external torque speeds it up
or slows it down. If a cat has no spin when it is released and
experiences no external torque, it ought not to be able to twist
around as it falls.

In the speed of its execution, the righting of a tumbling
cat resembles a magician's trick. The gyrations of the cat in
midair are too fast for the human eye to follow, so the process
is obscured. Either the eye must be speeded up, or the cat's
fall slowed down for the phenomenon to be observed. A century
ago the former was accomplished by means of high-speed
photography using equipment now available in any pharmacy.
But in the nineteenth century the capture on film of a falling
cat constituted a scientific experiment.

The experiment was described in a paper presented to the
Paris Academy in 1894. Two sequences of twenty photographs
each, one from the side and one from behind, show a
white cat in the act of righting itself. Grainy and quaint
though they are, the photos show that the cat was dropped
upside down, with no initial spin, and still landed on its feet
Careful analysis of the photos reveals the secret. As the cat
rotates the front of its body clockwise, the rear and tail twist
counterclockwise, so that the total spin remains zero, in perfect
accord with Newton's laws. Halfway down, the cat
pulls in its legs before reversing its twist and then extends
them again, with the desired end result. The explanation was
that while no body can acquire spin without torque, a flexible
one can readily change its orientation, or phase. Cats know
this instinctively, but scientists could not be sure how it
happened until they increased the speed of their perceptions a
thousandfold.

31.What does the passage mainly discuss?

(A) The explanation of an interesting phenomenon
(B) Miracles in modern science
(C) Procedures in scientific investigation

(C) By dropping a cat from a greater height.
(D) By studying Newton's laws of motion.


Question 39-50

The changing profile of a city in the United States is apparent
in the shifting definitions used by the United States Bureau
of the Census. In 1870 the census officially distinguished
the nation's "urban" from its "rural" population for the first
time. "Urban population" was defined as persons living in
towns of 8,000 inhabitants or more. But after 1900 it meant
persons living in incorporated places having 2,500 or more
inhabitants.

Then, in 1950 the Census Bureau radically changed its
definition of "urban" to take account of the new vagueness of
city boundaries. In addition to persons living in incorporated
units of 2,500 or more, the census now included those who
lived in unincorporated units of that size, and also all persons
living in the densely settled urban fringe, including both incor-
porated and unincorporated areas located around cities of
50,000 inhabitants or more. Each such unit, conceived as an
integrated economic and social unit with a large population
nucleus, was named a Standard Metropolitan Statistical Area
(SMSA).

Each SMSA would contain at least (a) one central city
with 50,000 inhabitants or more or (b) two cities having
shared boundaries and constituting, for general economic and
social purposes, a single community with a combined population
of at least 50,000, the smaller of which must have a population
of at least 15,000. Such an area included the county in
which the central city is located, and adjacent counties that are
found to be metropolitan in character and economically and
socially integrated with the country of the central city. By 1970,
about two-thirds of the population of the United States was
living in these urbanized areas, and of that figure more than
half were living outside the central cities.

While the Census Bureau and the United States government
used the term SMSA (by 1969 there were 233 of them),
social scientists were also using new terms to describe
the elusive, vaguely defined areas reaching out from what used
to be simple "town" and "cities". A host of terms came into
use: "metropolitan regions", "polynucleated population
groups", "conurbations", "metropolitan clusters",
"megalopolises", and so on.
