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.

In 1982, Mark Thatcher, the son of Mrs. Thatcher was reported 61 in the
Sahara Desert while competing in the Grand Prix motor race from Paris to Dakar.
This sad news, so 62 , shook the usually calm and unperturbed seasoned
politician 63 her balance. Though she did her best to pretend as if 64 had
happened and made her public appearances as usual, people could not 65 to notice
that she was no longer the old 66 prime minister who always had everything 67
control. 68 she had become a very sad mother who was unable to recover from her
shock.
One day, when she was to speak at a luncheon party, a reporter caught her 69
her guard by 70 up the subject of her missing son again. She was totally
mentally 71 for the question and lost her self control. Tears were rolling down
her eyes as she sobbingly told the reporter that there 72 still no news of Mark
and that she was very worried about him. She said that all the countries 73 had
promised to do their best to help her find her son. 74 that she broke down
completely and sobbed silently for quite a while. Gradually she 75 down and
started to speak as 76. it was a very moving scene which 77 a new side of Mrs.
Thatcher’s character the public do not usually see, 78 people began to talk
about the Iron Woman’s maternal love, a sentiment that is 79 to all human
kind.
Later Mark returned 80 and sound to his mother’s side, good-humored and all
smiles as usual, as if nothing unusual had ever happened. The Iron Woman,
however, broke down again as was sobbing for the second time.

In the last 12 years total employment in the United States grew faster than
at any time in the peacetime history of any country – from 82 to 110 million
between 1973 and 1985 – that is, by a full one third. The entire growth,
however, was in manufacturing, and especially in no – blue-collar jobs…
This trend is the same in all developed countries, and is, indeed, even more
pronounced in Japan. It is therefore highly probable that in 25 years developed
countries such as the United States and Japan will employ no larger a proportion
of the labor force I n manufacturing than developed countries now employ in
farming – at most, 10 percent. Today the United States employs around 18 million
people in blue-collar jobs in manufacturing industries. By 2010, the number is
likely to be no more than 12 million. In some major industries the drop will be
even sharper. It is quite unrealistic, for instance, to expect that the American
automobile industry will employ more than one –third of its present blue-collar
force 25 years hence, even though production might be 50 percent higher.
If a company, an industry or a country does not in the next quarter century
sharply increase manufacturing production and at the same time sharply reduce
the blue-collar work force, it cannot hope to remain competitive – or even to
remain “developed.” The attempt to preserve such blue – collar jobs is actually
a prescription for unemployment…
This is not a conclusion that American politicians, labor leaders or indeed
the general public can easily understand or accept. What confuses the issue even
more it that the United States is experiencing several separate and different
shifts in the manufacturing economy. One is the acceleration of the substitution
of knowledge and capital for manual labor. Where we spoke of mechanization a few
decades ago, we now speak of “robotization “ or “automation.” This is actually
more a change in terminology than a change in reality. When Henry Ford
introduced the assembly line in 1909, he cut the number of man – hours required
to produce a motor car by some 80 percent in two or three years –far more than
anyone expects to result from even the most complete robotization. But there is
no doubt that we are facing a new, sharp acceleration in the replacement of
manual workers by machines –that is, by the products of knowledge.

3.American politicians and labor leaders tend to dislike_____.
A.confusion in manufacturing economy
B.an increase in blue – collar work force

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.
