31-34 Two friends discussing weekend plans.
*Susan, I could really use your help this weekend.
*What is it, John? Another term paper?
*No, no. This is easy compared to that. My cousin is coming on Thursday. She has an interview at the college and I promised my aunt I look after her. We are going to the game on Friday, but Saturday I'm on duty at the library all day and can't get out of it. Uh, I was wondering if you could show her around during the day and maybe we can all meet for dinner later.
*Sure. I don't have any plans. What kind of things does she like to do?
*Actually I haven't seen her for three years. She lives so far away. But this will be her first time on a college campus, she is still in high school. So she probably enjoy anything on campus.
*Well, there is a music festival in the auditorium. That's a possibility. Only I hope it doesn't show. They are predicting 68 inches for the weekend. Everything will be closed down then.
*Well, how about for the time being. I'll plan on dropping her off at your place on the way to work, around eleven. But if there is a blizzard, I'll give you a call and see if we can figure something else out.
*Sounds good. Meantime I'll keep Saturday open. We can touch base Friday night when we have a better idea of the forecast.
*I hope this works out. I feel kind of responsible. She won't know a way around. And I want her to have a good time. Anyway I really appreciate your help. I owe you one.
*No problem I'll talk to you tomorrow.

33. What does John say about his cousin's interests?
34. What can be inferred about John's cousin?
35-37 A conversation in a university cafeteria.
*I see you are having the fish for lunch.
*That's right. Fish sticks and tomato soup, my favorites.
*I bet they were frozen.
*What?
*The fish sticks.
*Of course they were frozen. We are hundreds of miles from the ocean. The cafeteria can't afford to fly in fresh fish.
*I just mentioned it because an anecdote Professor Chambers told in class this morning.
*Which class?
*My American social history. It's a lot of fun.
*He talked about fish sticks?
*Not exactly. Bur he did talk about frozen fish. OK, this is back in 1920, right? It's 20 degrees below zero. And this guy Clarence Birdseye's out ice-fishing.
*Where is this, Antarctica?
*No. Massachusetts I think. Anyway he catches a fish and drops it beside him on the ice and it freezes solid.
*So?
*So, later at home he thaws out the fish in a bucket of water and it's alive. Of course Birdseye is amazed. But he eventually figures it out that the fish froze so fast that no large ice crystals fomed.
*What do you mean?
*Look, usually when a plant or animal cell freezes, large ice crystals form inside and eventually tear the cell walls. That's what kills the frozen plant or animal. And also what changes the taste of something that's been frozen. But if you freeze something quickly, only very small ice crystals form. So Birdseye invented the process of quick freezing food.
*And that was the beginning of the frozen foods?
*Right.
35. Why does the woman tell the man the story?
36. Why is it important to quick freeze fresh food?
37. What was Clarence Birdseye surprised to learn?
PART C
38 to 41 A lecture about the railroad industry.
At the beginning of the century the railroads were used to haul everything. Powerful railroad barons made fortunes without laving to be accountable to the public or considerable to the customers. But cars and trucks changed all of that. And by 1970, the rail industry was beset with problems. Trucks were taking all the new business. And even so the rail industry remained indifferent to customers. Also many regulations kept the rail industry from adjusting to shifting market. But in 1980, the rail industry entered the modern era when a deregulation bill was passed that allowed railroad companies to make quick adjustments to fees and practices. Companies reduced their lines by 1/3 and used fewer employees. They also took steps to minimize damage to product. And to increase their shipping capacity by stacking freight containers on railroad cars. To accommodate these taller loads, underpasses and tunnels were enlarged. The image of the rail industry has changed dramatically. Today companies are very responsive to customers and are gaining increasing market shares in the shipping industry. The railroad safety record is also strong. Freight trains have an accident rate that is only 1/3 that of the truck industry. Trains also come out ahead of the trucks on environmental grounds because they give off only 1/10 to 1/3 the pollution that is emitted by trucks. And railroading does not were out highways as trucks do.
38. What does the speaker mainly discuss?
39. What development caused a decline in the use of railroads?
40. What is one reason why the railroad industry is gaining public support?
41. According to the speaker, what expense does trucking public support?
42 to 45 Talk in an introductory biology class.
This coffee can contains soil from my garden. And I prepared slide samples to show you that it is alive. This ordinary backyard dirt is crawling with microbes. Microbes is not a very specific term. There are hundreds of thousands of different species called microbes. What they have to common is that we can't see them with a naked eye. They are microspopic. Look at this slide. You should see some round cells. Those are yeasts. Yeasts are fermenters. And they are necessary for making bread, beer, yogurt and so forth. Now look for an irregular shape with hairs coming out of it. That's a mold. Molds are decomposers, and they are responsible for the decomposition of my compile teeth. You should also see some protozoa. Some protozoa, like the one causes malaria are harmful to people. A microbic causes disease is called a pathogen. Finally you should see a lot of squiggly lines. They are bacteria. The oldest form of life on earth. Like the other microbes, bacteria are single-cells do not have a nuclear. So I've got about a teaspoon of soil in my hand here. In that teaspoon are about ten thousand protozoa, 200 thousand mold cells, a million yeast, probably a billion bacteria.
42. What is the main purpose of the talk?
43. Why did the speaker take a soil sample from his garden?
44. What does the speaker imply about yeasts?
45. What does the speaker ask the class to look at during the talk?
1996年5月托福阅读全真试题
Question 1-12
Orchids are unique in having the most highly developed
of all blossoms, in which the usual male and female reproductive
organs are fused in a single structure called the column.
The column is designed so that a single pollination will fertilize
hundreds of thousands, and in some cases millions, of seeds,
so microscopic and light they are easily carried by the breeze.
Surrounding the column are three sepals and three petals,
sometimes easily recognizable as such, often distorted into gorgeous,
weird, but always functional shapes. The most noticeable
of the petals is called the labellum, or lip. It is often dramatically
marked as an unmistakable landing strip to attract
the specific insect the orchid has chosen as its pollinator.
To lure their pollinators from afar, orchids use appropriately
intriguing shapes, colors, and scents. At least 50 different
aromatic compounds have been analyzed in the orchid family,
each blended to attract one, or at most a few, species of
insects or birds. Some orchids even change their scents to interest
different insects at different times.
Once the right insect has been attracted, some orchids
present all sorts of one-way obstacle courses to make sure it
does not leave until pollen has been accurately placed or removed.
By such ingenious adaptations to specific pollinators,
orchids have avoided the hazards of rampant crossbreeding in
the wild, assuring the survival of species as discrete identities.
At the same time they have made themselves irresistible to collectors.

Question 13-22
One of the most important social developments that
helped to make possible a shift in thinking about the role of
public education was the effect of the baby boom of the 1950's
and 1960's on the schools. In the 1920's, but especially in
the Depression conditions of the 1930's, the United States
experienced a declining birth rate -every thousand women aged
fifteen to forty-four gave birth to about 118 live children in
1920, 89.2 in 1930, 75.8 in 1936, and 80 in 1940. With the
growing prosperity brought on by the Second World War and
the economic boom that followed it, young people married and
established households earlier and began to raise larger families
than had their predecessors during the Depression. Birth rates
rose to 102 per thousand in 1946, 106.2 in 1950, and 118 in
1955. Although economics was probably the most important
determinant, it is not the only explanation for the baby boom.
The increased value placed on the idea of the family also helps
to explain this rise in birth rates. The baby boomers began
streaming into the first grade by the mid-1940's and became a
flood by 1950. The public school system suddenly found itself
overtaxed. While the number of schoolchildren rose because of
wartime and postwar conditions, these same conditions made
the schools even less prepared to cope with the flood. The
wartime economy meant that few new schools were built between
1940 and 1945. Moreover, during the war and in the boom
times that followed, large numbers of teachers left their
profession for better-paying jobs elsewhere in the economy.
Therefore, in the 1950's and 1960's, The baby boom
hit an antiquated and inadequate school system. Consequently,
the "custodial rhetoric" of the 1930's and early 1940's no
longer made sense; that is, keeping youths aged sixteen and
older out of the labor market by keeping them in school could
no longer be a high priority for an institution unable to find
space and staff to teach younger children aged five to sixteen.
With the baby boom, the focus of educators and of laymen
interested in education inevitably turned toward the lower grades
and back to basic academic skills and discipline. The system no
longer had much interest in offering nontraditional, new, and
extra services to older youths.
13.What does the passage mainly discuss?
(A) The teaching profession during the baby boom

Questions 23-32
Nineteenth-century writers in the United States,
whether they wrote novels, short stories, poems, or plays,
were powerfully drawn to the railroad in its golden year. In
fact, writes responded to the railroads as soon as the first
were built in the 1830's. By the 1850's, the railroad was a
major presence in the life of the nation. Writers such as Ralph
Waldo Emerson and Henry David Thoreau saw the railroad
both as a boon to democracy and as an object of suspicion. The
railroad could be and was a despoiler of nature; furthermore,
in its manifestation of speed and noise, it might be a despoiler
of human nature as well. By the 1850's and 1860's, there
was a great distrust among writer and intellectuals of the rapid
industrialization of which the railroad was a leading force.
Deeply philosophical historians such as Henry Adams lamented
the role that the new frenzy for business was playing in eroding
traditional values. A distrust of industry and business continued
among writers throughout the rest of the nineteenth century
and into the twentieth.
For the most part, the literature in which the railroad
plays an important role belong to popular culture rather than to
the realm of serious art. One thinks of melodramas, boys'
books, thrillers, romances, and the like rather than novels of
the first rank. In the railroads' prime years, between 1890
and 1920, there were a few individuals in the United States,
most of them with solid railroading experience behind them,
who made a profession of writing about railroading-works
offering the ambience of stations, yards, and locomotive cabs.
These writers, who can genuinely be said to have created a
genre, the "railroad novel." are now mostly forgotten, their
names having faded from memory. But anyone who takes the
time to consult their fertile writings will still find a treasure
trove of information about the place of the railroad in the lift
of the United States.
23.With which of the following topics is the passage mainly concerned?
(A) The role of the railroad in the economy of the United States.
(B) Major nineteenth-century writers.
(C) The conflict between expanding industry and preserving nature.

(A) railroad
(B) manifestation
(C) speed
(D) nature
25.In the first paragraph, the author implies that writers' reactions to the development of railroads were
(A) highly enthusiastic
(B) both positive and negative
(C) unchanging
(D) disinterested
26.The word "lamented" in line 14 is closest in meaning to
(A) complained about
(B) analyzed
(C) explained
(D) reflected on

(A) grew in
(B) disappeared from
(C) remained in
(D) developed from
32.What is the author's attitude toward the "railroad novels" and other books about railroads written between 1890 and 1920?
(A) They have as much literary importance as the books written by Emerson, Thoreau, and Adams.
(B) They are good examples of the effects industry and business had on the literature of the United States.
(C) They contributed to the weakening of traditional values.
(D) They are worth reading as sources of knowledge about the impact of railroad on life in the United States.
Questions 33-44
By the 1820's in the United States, when steamboats
were common on western waters, these boats were mostly
powered by engines built in the West (Pittsburgh, Cincinnati,
or Louisville), and of a distinctive western design specially
suited to western needs. The first steam engines in practical
use in England and the United States were of low pressure
design. This was the type first developed by James Watt, then
manufactured by the firm of Boulton and Watt, and long the
standard industrial engine. Steam was accumulated in a large,
double-acting vertical cylinder, but the steam reached only a
few pounds of pressure per square inch. It was low-pressure
engines of this type that were first introduced into the United
States by Robert Fulton. He imported such a Boulton and
Watt engine from England to run the Clermont. But this type
of engine was expensive and complicated, requiring many
precision-fitted moving parts.
The engine that became standard on western steamboats
was of a different and novel design. It was the work primarily
of an unsung hero of American industrial progress, Oliver
Evans(1755-1819). The self-educated son of a Delaware
farmer. Evans early became obsessed by the possibilities of
mechanized production and steam power. As early as 1802 he
was using a stationary steam engine of high-pressure design in
his mill. Engines of this type were not unknown, but before
Evans they were generally considered impractical and
dangerous.
Within a decade the high-pressure engine, the new type,
had become standard on western waters. Critics ignorant of
western conditions often attacked it as wasteful and dangerous.
But people who really knew the Ohio, the Missouri, and
the Mississippi insisted, with good reasons, that it was the only
engine for them. In shallow western rivers the weight of
vessel and engine was important; a heavy engine added to the
problem of navigation. The high-pressure engine was far
lighter in proportion to horsepower, and, with less than half
as many moving parts, was much easier and cheaper to repair.
The main advantages of low-pressure engines were safe operation
and economy of fuel consumption, neither of which meant
much in the West.
33.What is the passage mainly about?

Questions 45-50
Volcanic fire and glacial ice are natural enemies. Eruptions
at glaciated volcanoes typically destroy ice fields, as they
did in 1980 when 70 percent of Mount Saint Helens ice cover
was demolished. During long dormant intervals, glaciers gain
the upper hand cutting deeply into volcanic cones and eventually
reducing them to rubble. Only rarely do these competing
forces of heat and cold operate in perfect balance to create a
phenomenon such as the steam caves at Mount Rainier
National Park.
Located inside Rainier's two ice-filled summit craters,
these caves form a labyrinth of tunnels and vaulted chambers
about one and one-half miles in total length. Their creation
depends on an unusual combination of factors that nature
almost never brings together in one place. The cave-making
recipe calls for a steady emission of volcanic gas and heat, a
heavy annual snowfall at an elevation high enough to keep it
from melting during the summer, and a bowl-shaped crater to
hold the snow.
Snow accumulating yearly in Rainier's summit craters is
compacted and compressed into a dense form of ice called firn,
a substance midway between ordinary ice and the denser crystalline
ice that makes up glaciers. Heat rising from numerous
openings (called fumaroles) along the inner crater walls melts
out chambers between the rocky walls and the overlying ice
pack. Circulating currents of warm air then melt additional
opening in the firn ice, eventually connecting the individual
chambers and, in the larger of Rainier's two craters, forming
a continuous passageway that extends two- thirds of the way
around the crater's interior.
To maintain the cave system, the elements of fire under
ice must remain in equilibrium. Enough snow must fill the
crater each year to replace that melted from below. If too
much volcanic heat is discharged, the crater's ice pack will
melt away entirely and the caves will vanish along with the
snow of yesteryear. If too little heat is produced, the ice,
replenished annually by winter snowstorms, will expand, pushing
against the enclosing crater walls and smothering the present
caverns in solid firn ice.
45.With what topic is the passage primarily concerned?
(A) The importance of snowfall for Mount Rainier.
(B) The steam caves of Mount Rainier.
