Passage 4
Questions 16 to 20 are based on the following passage:
Successful innovations have driven many older technologies to extinction and
have resulted in higher productivity, greater consumption of energy, increased
demand of raw materials, accelerated flow of materials through the economy and
increased quantities of metals and other substances in use each person. The
history of industrial development abounds with examples.
In 1870, horses and mules were the prime source of power on U.S. farms. One
horse or mule was required to support four human beings a ratio that remained
almost constant for many decades. At that time, had a national commission been
asked to forecast the population for 1970, its answer probably would have
depended on whether its consultants were of an economic or technological turn of
mind. Had they been “economists”, they would probably have projected the 1970
horses or mule population to be more than 50 million. Had they been
“technologists”, they would have recognized that the power of steam had already
been harnessed to industry and to learn and ocean transport. They would have
recognized further that it would be the prime source of power on the farm. It
would have been difficult for them to avoid the conclusion that the horse and
mule population would decline rapidly.
16. According to the passage, what supplied most of the power on U.S. farms
in 1870?
A. Animals B. Humans C. Engines D. Water
17. Which of the following is NOT mentioned by the author as a consequence of
new technological developments?

A. technology began to be more economical
B. the steam engine had been invented
C. the U.S. horse population was about 10 million
D. a national commission was about 10 million
19. In the second paragraph, the author suggests that “economists” would
.
A. plan the economy through yearly forecasts
B. fail to consider the influence of technological innovation
C. value the economic contribution of farm animals
D. consult the national commission on the economy
20. What is the author’s attitude toward changes brought on by technological
innovations?
A. He is excited about them.
B. He accept them as natural.
C. He is disturbed by them.
D. He questions their usefulness.
Part I Reading Comprehension
Passage 1
Questions 1 to 5 are based on the following passage:
In Washington D.C., 1600 Pennsylvania Avenue is a very special address. It is
the address of the White House, the home of the president of the United
States.
Originally the White House was gray and was called the Presidential Palace.
It was built from 1792 to 1800. at this time, the city of Washington itself was
being built; it was to be the nation’s new capital city. George Washington, the
first president, and Pierre Charles L’Enfant, a French engineer, chose the place
for the new city. L’Enfant then planned they city. The president’s home was an
important part of the plan.
A contest was held to pick a design for the president’s home. An architect
named James Hoban won. He designed a large three-story house of gray stone.
President Washington never lived in the President Palace. The first president
to live there was John Adams, the second president of the United States, and his
wife Mrs. Adams did not really like hew new house. In her letters, she often
complained about the cold. Fifty fireplaces were not enough to keep the house
warm!
In 1812 the United States and Britain went to war. In 1814 the British
invaded Washington. Theu burned many buildings, including the Presidential
Palace.
After the war James Hoban, the original architect, partially rebuilt the
president’s homes. To cover the marks of the fire, the building was painted
white. Before long it became known as the White House.
The White House is one of the most popular tourist attractions in the United
States. Every year more than 1.5 million visitors go through the five rooms that
are open to the public.
1. The White House was built in Washington .

Part III Cloze
Directions: There are twenty blanks in the following passage. For each blank there are four choices. Choose the one that best fits into the passage and then marks your answer on the Answer Sheet.
What makes a child speak a language has long been a puzzle to linguists. 61 speaking, there are two schools of linguists, both of whom try to explain 62 a child picks up a language so easily. The fact that a child picks a language 63 is 64 : At one year old, a child is able to say “bye-bye”; at two, he is able to
use fifty; by there he begins to 65 tenses. The famous American linguist Noam Chomsky 66 that human being have a sort of built-in system for language use, and that the 67 is 68 . Children are not taught language 69 they are taught arithmetic. Other linguists, 70 , hold the view that a child learns 71 of his
language from the hints in the environment. 72 , theorists of both schools 73 that there is a biological basis for language use. The 74 is which is more important, the inner ability or the environment. This is certainly a field 75 to be explored. Researchers from both schools are busy finding evidence to 76 their own theory, but 77 side is persuading the other.
It seems that in order to 78 why a child learns a language so easily, we have to 79 the joint efforts of both schools. Some linguist, like De Villiers, has recognized the value of cooperation, and 80 linguists of both sides to work together.

We can begin our discussion of “population as global issue” with what most persons mean when they discuss “the population problem”: too many people on earth and a too rapid increase in the number added each year. The facts are not in dispute, It was quite right to employ the analogy that likened demographic growth to “a long, thin powder fuse that burns steadily and haltingly until it finally reaches the charge and explodes.”
To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history, we find that populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility
in most places, but this was usually balanced by high mortality. For most of human history, it was seldom the case that one in ten persons would live past forty, while infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.
This pattern is important to notice. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden enthusiasm for more children, but an improvement in the conditions that traditionally have caused high mortality.
Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8,000 BC.till approximately AD. 1650. In the first period of some 9600 years, the population increased from some 8
million to 500 million in 1650. Between 1650 and the present, the population has increased from 500 million to more than 4 billion. And it is estimated that by the year 2000 there will be 6.2 billion people throughout the world. One way to
appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000BC and 1650, an average of only 50,000 persons was being added annually to the world’s population each year. At present, this number is added every six hours. The increase is about 80,000,000 persons annually.
1.Which of the following demographic growth pattern is most suitable for the
long thin powder fuse analogy?
A.A virtually stable or slightly decreasing period and then a sudden
explosion of population.
B.A slow growth for a long time and then a period of rapid, dramatic
increase.
C.Too many people on earth and a few rapid increase in the number added each
year.
D.A long period when death rates exceeds birthrates and then a short period
with higher fertility and lower mortality.
2.During the first period of demographic history, societies were often in
danger of extinction because___.
A.only one in ten persons could live past 40.
B.there was higher mortality than fertility in most places.
C.it was too dangerous to have babies due to the poor conditions.
D.our ancestors had little enthusiasm for more children.
3.Which statement is true about population increase?
A.There might be an increase of 2.2 billion persons from now to the year
2000.
B.About 50,000 babies are born every six hours at present.
C.Between 8000 BC and the present, the population increase is about
80,000,000 persons each year.
D.The population increased faster between 8000BC and 1650 than between 1650
and the present.
4.The author of the passage intends to___.
A.warn people against the population explosion in the near future.
B.compare the demographic growth pattern in the past with that after
1650.
C.find out the cause for rapid increase in population in recent years.
D.present us a clear and complete picture of the demographic growth.
5.The word “demographic” in the first paragraph means___.
A.statistics of human.
B.surroundings study.
C.accumulation of human.
D.development of human.
Passage 2
Questions 6 to 10 are based on the following passage:
The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown tat 40 percent of cancer is related to the diet as well, especially cancer of the colon.
Different cultures ate more prone to get certain illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates and nitrites, commonly used to preserve color in meats, and other food additives,
caused cancer. Yet these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives that we eat are not all so direct. Farmers often give penicillin to beef and poultry, and because of
this, penicillin has been found in the milk of treated cows. Sometimes similar drugs are administered to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.
6. How has science done a disservice to mankind?
A. Because of science, most of the foods we eat today are contaminated.
B. It has caused a lack of information concerning the value of food.
C. As a result of scientific intervention, some potentially harmful
substances has been added to our food.
D. The scientists have preserved the color of meats, but not of
vegetables.
7. What are nitrates used for?
A. They preserves flavor in packaged foods.
B. They preserve the color of meats.
C. They are the objects of research.
D. They cause the animals to become fatter.
8. The FDA has tried repeatedly to control .
A. the attempt to fatten the animals
B. the attempt to cure sick animals
C. the using of drugs to animals
D. the using of additives to preserve the dolor of food
9. The word “carcinogenic” means most nearly the same as .
A. trouble-making B. color-retaining
C. money-saving D. cancer-causing
10. Which of the following statements is NOT true?
A. Drugs are always given to animals for medical reasons.
B. Some of the additives in our food are added to the food itself and some
are given to the living animals.
C. Researchers have known about the potential hazards of the food additives
for over thirty-five years.
D. Food may cause forty percent of cancer in the world.
