Part B
Questions 31-34 Listen to a conversation at a bicycle shop.
Hi, John.
Oh, hi, Laura. What are you doing here?
Uh, I’m usually here on weekends. It’s my dad’s shop. So, you are looking for a bike?
Yeah. Now the weather is warming up. I thought I’d get some exercise instead of taking the bus all the time.
Well, you came to the right place. Do you know what you’d like?
Well, I don’t want a racer or a touring bike or anything. Mostly I’ll just be using it to get me back and forth from work.
How far is that?
About four miles.
Are there a lot of hills on the way?
Some I guess. But, um, maybe I should just tell you in front that I’ve only got a hundred and fifty dollars. Can I get anything decent for that?
Well, you’re not going to get anything top of the line. But we do have a few trade-ins
in the back that are in good condition.
That sounds good.
And you’re right. For the kind of riding you’re going to be doing, the most important thing is comfort. You want to make sure it’s the right height for you. Follow me and I’ll show you what we’ve got.

31. Why is Laura at the bicycle shop?

32. Why does John want to buy a bicycle?

33. What does Laura suggest that John do?

34. What does Laura say is most important about a bike?

Questions 35-39 Listen to a conversation between two students.
Hi, Lynn. I saw you at registration yesterday. I sailed right through, but you were standing in a long line.
Yeah. I waited an hour to sign up for a distance-learning course.
Distance learning? Never heard of it.
Well, it’s new this semester. It’s only open to psychology majors. But I bet it’ll catch on else where. Yesterday, over a hundred students signed up.
Well, what is it?
It’s an experimental course. I registered for child psychology. All I have got to do is watch a twelve-week series of televised lessons. The department shows them seven different times a day and in seven different locations.
Don’t you ever have to meet with professor?
Yeah. After each part of the series I have to talk to her and the other students on the phone, you know, about our ideas. Then we’ll meet on campus three times for reviews and exams.
It sounds pretty non-traditional to me. But I guess it makes sense, considering how many students have jobs. It must really help with their schedules, not to mention how it will cut down on traffic.
You know, last year my department did a survey and they found out that 80 percent of all psychology majors were employed. That’s why they came up with the program.
Look, I’ll be working three days a week next semester and it was either cut back on my classes or try this out.
The only thing is: doesn’t it seem impersonal though? I mean, I miss having class discussions and hearing what other people think.
Well, I guess that’s why phone contact’s important. Any way, it’s an experiment.
Maybe I’ll end up hating it.
Maybe. But I’ll be curious to see how it works up.

35. Where did the man see the woman yesterday?

36. How was the distance-learning course different from traditional courses?

37. What do the speakers agree is the major advantage of the distance-learning course?

38. Why did the woman decide to enroll in the distance-learning course?

39. What does the man think is a disadvantage of distance learning?

Part C
Questions 40-43 Listen to a student report in the United States history class. So, uh, as Jim said, James Polk was the eleventh president. And, um, my report’s about the next president Zachary Taylor. Taylor was elected in 1849. It’s surprising because he was the first president that didn’t have any previous political experience. The main reason he was chosen as a candidate was because he was a war hero.
In the army his men called him old, rough and ready, I guess because of his rough edges. He was kind of blunt and he didn’t really look like a military hero. He liked to do things like wearing civilian clothes instead of uniform even in battle. And he was so short and plump that he had to be lifted up on his horse. But he did win a lot of battles and he became more and more popular. So the Whig party decided to nominate him for the presidency, even though no one knew anything about where he stood on the issues. I couldn’t find much about his accomplishments, probably because he was only in office about a year and a half before he died. But one thing, he pushed for the development of the transcontinental railroad because he thought it was important to form a link with the west coast. There was a lot of wealth in California and Oregon from commerce and minerals and stuff. Also he established an agricultural bureau in the department of the Interior and promoted more government aid to agriculture.
Well, that’s about all I found. Like I said he died in office in 1850, so his vice president took over. And that’s the next report. So, thank you.

40. Why was Zachary Taylor chosen by his party as a candidate for president?

41. According to the speaker, why is it surprising that Taylor was elected president?

42. Why did Taylor accomplish relatively little as president?

43. What will the class probably do next?

Questions 44-46 Listen to a talk at a special event.
I want to welcome each and every balloon enthusiast in Philadelphia. Thank you for coming here this morning to commemorate the first balloon voyage in the United States. On January ninth, 1793, at ten o’clock in the morning, a silk balloon lifted into the skies above this city, which was at that time the capital of the country. According to the original records of the flight, the voyage lasted 46 minutes, from its departure in Philadelphia to its landing across the Delaware River in New Jersey.
Though our pilots today will try to approximate the original landing site, they are at the mercy of the winds, so who knows where they’ll drift off to. Even the balloonist in 1793 experienced some uncertain weather that day. There were clouds, fog and mist in various directions.
Our reenactment promises to be nothing less than spectacular. The yellow balloon directly behind me is five storeys high. It’s inflated with helium, unlike the original, which was filled with hydrogen and unbeknownst to the pilots, potentially explosive. Gas filled models are pretty uncommon now because of the extremely high cost. So the eighty other balloons in today’s lunch are hot air heated by propane burners. These balloons are from all over the country.

44. What is the purpose of the balloon lunch?

45. What problem might today’s pilots encounter?

46. What does the speaker imply about helium balloons?

Questions 47-50 Listen to part of a lecture in a geology class.
I’m glad you brought up the question of our investigations into the makeup of the earth’s interior. In fact, since this is the topic of your reading assignment for next time, let me spend these last few minutes of class talking about that.
There were several important discoveries in the early part of the century to help geologists develop a more accurate picture of the earth’s interior. The first key discovery had to do with seismic waves. Remember, they are the vibrations caused by earthquakes. Well, scientists found that they travel thousands of miles through the earth’ s interior. This finding enabled geologists to study the inter parts of the earth.
You see, these studies revealed that these vibrations were of two types: compression or P waves and shear or S waves. And researchers found that P waves travel through both liquids and solids while S waves travel only through solid matter. In 1906, a British geologist discovered that P waves slowed down at a certain depth but kept traveling deeper. On the other hand, S waves either disappeared or were reflected back. So he concluded that the depth marked the boundary between a solid mantle and the liquid core. Three years later, another boundary was discovered, that between the mantle and the earth’s crust.
There are still a lot to be learned about the earth. For instance, geologists know that the core is hot. Evidence of this is the molten lava that flows out of volcanoes. But we are still not sure what the source of the heat is.

47. What is the purpose of the talk?

48. What important discovery about seismic waves does the instructor mention?

49. What did the study of seismic vibrations help geologists learn more about?

50. What did P and S waves help scientists discover about the layers of the earth?

Question 1-7

Hotels were among the earliest facilities that bound the
United States together. They were both creatures and creators
of communities, as well as symptoms of the frenetic quest for
community. Even in the first part of the nineteenth century,
Americans were already forming the habit of gathering from all
corners of the nation for both public and private, business and
pleasure purposes. Conventions were the new occasions, and
hotels were distinctively American facilities making conven-
tions possible. The first national convention of a major party to
choose a candidate for President (that of the National Republican
party, which met on December 12, 1831, and nominated
Henry Clay for President) was held in Baltimore, at a hotel
that was then reputed to be the best in the country. The
presence in Baltimore of Barnum s City Hotel, a six-story building
with two hundred apartments helps explain why many other
early national political conventions were held there.

In the longer run, too. American hotels made other national
conventions not only possible but pleasant and convivial.
The growing custom of regularly assembling from afar the
representatives of all kinds of groups - not only for political conventions,
but also for commercial, professional, learned, and
avocational ones - in turn supported the multiplying hotels. By
mid-twentieth century, conventions accounted for over a third
of the yearly room occupancy of all hotels in the nation, about
eighteen thousand different conventions were held annually
with a total attendance of about ten million persons.

Nineteenth-century American hotelkeepers, who were no
longer the genial, deferential "hosts" of the eighteenth-century
European inn, became leading citizens. Holding a large
stake in the community, they exercised power to make it
prosper. As owners or managers of the local "palace of the
public", they were makers and shapers of a principal community
attraction. Travelers from abroad were mildly shocked by this
high social position.

1. The word "bound" in line 1 is closest in meaning to

(A) led
(B) protected
(C) tied
(D) strengthened

2. The National Republican party is mentioned in line 10 as an example of a group

(A) from Baltimore
(B) of learned people
(C) owning a hotel
(D) holding a convention

3. The word "assembling" in line 19 is closest in meaning to

(A) announcing
(B) motivating
(C) gathering
(D) contracting

4. The word "ones" in line 22 refers to

(A) hotels
(B) conventions
(C) kinds
(D) representatives

5. The word "it" in line 30 refers to
(A) European inn
(B) host
(C) community
(D) public

6. It can be inferred from the passage that early hotelkeepers in the United States were

(A) active politicians
(B) European immigrants
(C) Professional builders
(D) Influential citizens

7. Which of the following statements about early American hotels is NOT mentioned in the
passage?

(A) Travelers from abroad did not enjoy staying in them.
(B) Conventions were held in them
(C) People used them for both business and pleasure.
(D) They were important to the community.

Question 8-17

Beads were probably the first durable ornaments humans
possessed, and the intimate relationship they had with their
owners is reflected in the fact that beads are among the most
common items found in ancient archaeological sites. In the
past, as today, men, women, and children adorned them-
selves with beads. In some cultures still, certain beads are
often worn from birth until death, and then are buried with
their owners for the afterlife. Abrasion due to daily wear alters
the surface features of beads, and if they are buried for long,

the effects of corrosion can further change their appearance.
Thus, interest is imparted to the bead both by use and the
effects of time.

Besides their wear ability, either as jewelry or incorporated
into articles of attire, beads possess the desirable characteristics
of every collectible, they are durable, portable, available
in infinite variety, and often valuable in their original cultural
context as well as in today s market. Pleasing to look at and
touch, beads come in shapes, colors, and materials that almost
compel one to handle them and to sort them.

Beads are miniature bundles of secrets waiting to be
revealed: their history, manufacture, cultural context, economic
role, and ornamental use are all points of information one
hopes to unravel. Even the most mundane beads may have
traveled great distances and been exposed to many human
experiences. The bead researcher must gather information from
many diverse fields. In addition to having to be a generalist
while specializing in what may seem to be a narrow field, the
researcher is faced with the problem of primary materials that
have little or no documentation. Many ancient beads that are
of ethnographic interest have often been separated from their
original cultural context.

The special attractions of beads contribute to the uniqueness
of bead research. While often regarded as the "small
change of civilizations", beads are a part of every culture, and
they can often be used to date archaeological sites and to
designate the degree of mercantile, technological, and cultural
sophistication.

Question 18-31

In the world of birds, bill design is a prime example of
evolutionary fine-tuning. Shorebirds such as oystercatchers use
their bills to pry open the tightly sealed shells of their prey,
hummingbirds have stiletto-like bills to probe the deepest
nectar-bearing flowers, and kiwis smell out earthworms thanks to
nostrils located at the tip of their beaks. But few birds are
more intimately tied to their source of sustenance than are
crossbills. Two species of these finches, named for the way
the upper and lower parts of their bills cross, rather than meet
in the middle, reside in the evergreen forests of North America
and feed on the seeds held within the cones of coniferous trees.

The efficiency of the bill is evident when a crossbill locates
a cone. Using a lateral motion of its lower mandible, the
bird separates two overlapping scales on the cone and exposes
the seed. The crossed mandibles enable the bird to exert a
powerful biting force at the bill tips, which is critical for
maneuvering them between the scales and spreading the scales
apart. Next, the crossbill snakes its long tongue into the gap
and draws out the seed. Using the combined action of the bill
and tongue, the bird cracks open and discards the woody seed
covering action and swallows the nutritious inner kernel. This whole
process takes but a few seconds and is repeated hundreds of
times a day.

The bills of different crossbill species and subspecies vary -
some are stout and deep, others more slander and shallow. As
a rule, large-billed crossbills are better at securing seeds from
large cones, while small-billed crossbills are more deft at
removing the seeds from small, thin-scaled cones. Moreover,
the degree to which cones are naturally slightly open or tightly
closed helps determine which bill design is the best.

One anomaly is the subspecies of red crossbill known as
the Newfoundland crossbill. This bird has a large, robust bill,
yet most of Newfoundland s conifers have small cones, the
same kind of cones that the slender-billed white-wings rely on.

18.What does the passage mainly discuss?

(A) The importance of conifers in evergreen forests
(B) The efficiency of the bill of the crossbill
(C) The variety of food available in a forest

Question 32-38

If you look closely at some of the early copies of the De-
laration of Independence, beyond the flourished signature of
John Hancock and the other 55 men who signed it, you will
also find the name of one woman, Mary Katherine Goddard.
It was she, a Baltimore printer, who published the first official
copies of the Declaration, the first copies that included the
names of its signers and therefore heralded the support of all
thirteen colonies.

Mary Goddard first got into printing at the age of twenty-
four when her brother opened a printing shop in Providence,
Rhode Island, in 1762. When he proceeded to get into trouble
with his partners and creditors, it was Mary Goddard and her
mother who were left to run the shop. In 1765 they began
publishing the Providence Gazette, a weekly newspaper.
Similar problems seemed to follow her brother as he opened
businesses in Philadelphia and again in Baltimore. Each time Ms.
Goddard was brought in to run the newspapers. After starting
Baltimore s first newspaper, The Maryland Journal, in
1773, her brother went broke trying to organize a colonial
postal service. While he was in debtor s prison. Mary Katherine
Goddard s name appeared on the newspaper s masthead
for the first time.

When the Continental Congress fled there from Philadelphia
in 1776, it commissioned Ms. Goddard to print the first
official version of the Declaration of Independence in January
1777. After printing the documents, she herself paid the post
riders to deliver the Declaration throughout the colonies.

During the American Revolution, Mary Goddard continued
to publish Baltimore s only newspaper, which one historian
claimed was "second to none among the colonies". She was
also the city s postmaster from 1775 to 1789 - appointed by
Benjamin Franklin - and is considered to be the first woman
to hold a federal position.

32.With which of the following subjects is the passage mainly concerned?
(A) The accomplishments of a female publisher
(B) The weakness of the newspaper industry

Question 39-50

Galaxies are the major building blocks of the universe. A
galaxy is giant family of many millions of stars, and it is held
together by its own gravitational field. Most of the material
universe is organized into galaxies of stars together with
gas and dust.

There are three main types of galaxy: spiral, elliptical,
and irregular. The Milky Way is a spiral galaxy, a flattish disc
of stars with two spiral arms emerging from its central nucleus.
About one-quarter of all galaxies have this shape. Spiral
galaxies are well supplied with the interstellar gas in which
new stars form: as the rotating spiral pattern sweeps around
the galaxy it compresses gas and dust, triggering the formation
of bright young stars and in its arms. The elliptical galaxies have a
symmetrical elliptical or spheroidal shape with no obvious
structure. Most of their member stars are very old and since
ellipticals are devoid of interstellar gas, no new stars are forming
in them. The biggest and brightest galaxies in the universe
are ellipticals with masses of about 1013 times that of the Sun,
these giants may frequently be sources of strong radio
emission, in which case they are called radio galaxies. About two-
thirds of all galaxies are elliptical. Irregular galaxies comprise
about one-tenth of all galaxies and they come in many
subclasses.

Measurement in space is quite different from measure-
ment on Earth. Some terrestrial distances can be expressed as
intervals of time, the time to fly from one continent to another
or the time it takes to drive to work, for example. By comparison
with these familiar yardsticks, the distances to the
galaxies are incomprehensibly large, but they too are made
more manageable by using a time calibration, in this case the
distance that light travels in one year. On such a scale the
nearest giant spiral galaxy, the Andromeda galaxy, is two
million light years away. The most distant luminous objects seen
by telescopes are probably ten thousand million light years
away. Their light was already halfway here before the Earth
even formed. The light from the nearby Virgo galaxy set out
when reptiles still dominated the animal world.

39.The word "major" in line 1 is closest in meaning to

(A) intense
(B) principal
(C) huge
(D) unique

40.What does the second paragraph mainly discuss?

(A) The Milky Way
