Most people work to earn a living and they

produce goods and services. Goods are either

agricultural (like maize) or manufactured (like

cars). Services are such things like education, 1._________

medicine, and commerce. These people provide 2.__________

goods; some provide services. Other people provide

both goods or services. For example, in the same 3.__________

garage a man may buy a car or some service which

helps him maintain his car.

The work people do is called as economic 4.__________

activity. All economic activities taken together make

up the economic system of a town, a city, a country,

or the world. Such economic system is the sum-total 5.__________

of what people do and what they want. The work

people do either provides what they need or provides

the money with that they can buy essential 6.__________

commodities. Of course, most people hope to have

enough money to buy commodities and services which

are essential but which provide some particular 7. __________

personal satisfaction, such as toys for children, visits 8. __________

the cinema, and books.

The science of economics is basic upon the facts 9. __________

of our everyday lives. Economists study our everyday

lives and the general life of our communities in order

economy in which we live, and to explain how it

works. The economist methods should of course be 10. __________

II.

Crime has its own cycles, a magazine reported

some years before. Police records that were studied 1.__________

for five years from over 2400 cities and towns show

a surprised link between changes in the season and 2.__________

crime patterns.

The pattern of crime has varied very little

over a long period of years. Murder reaches its high record

during July and August, as does rape and other violent 3.__________

attacks. Murder, however, is more than seasonal: it is a 4.__________

weekend crime. It is also a nighttime crime: 62 percent

of members are committed between 6 p.m. and 6 a.m.

Unlike the summer high in crimes of bodily harm,

burglary has a different cycle. You are most likely

to being robbed between 6 p.m. and 2 a.m. on a Saturday 5.__________

night in December, January, or February. The most

uncriminal month of all? May--except for one strange

statistic. More dog bites are reported in this month

than in an other month of the year. 6.__________

Apparent our intellectual seasonal cycles are 7.__________

completely different from our criminal tendencies.

professor Huntington, of the Foundation for the Study

of Cycles, made extensive studies to discover the

seasons when people read serious books, attend scientific

meetings, make the highest scores on examinations,

and to propose the most changes to patents. In all 8.__________

instances, he found a spring peak and an autumn peak

separated by a summer low. On other hand, Professor 9.__________

Huntington’s studies indicated that June is the peak

month for suicides and admissions in mental hospitals. 10.__________

June is also a peak month for marriages!

2. surprised → surprising

4. however → moreover

5. being → be

III.

For centuries the gypsies have lived as a unfettered people 1.__________

who traveled through half the countries of the world,

abiding to their own laws. Scorning discomfort, 2.__________

enduring persecution, accumulating only meager possession, 3.__________

they sacrificed all for their freedom.

To be settled people they seemed both fascinating or fearful,

4.__________

while to the gypsies the settling people were equally fearful.

5.__________

Gypsies acquired in ancient times their traditional occupations

like smiths and horse traders. They plied their crafts

6.__________

from village to village, presenting entertainments to attract townsmen. So they

became musicians, magicians, animal trainers, and acrobats.

A folk saying held that when a gypsy woman predicted misfortune

it always came fact because she stole something from the victim. 7.__________

The gypsies were known also for the big trick which they 8.__________

deceived the credulous.

A typical trick was to convince a peasant to bury his money, 9.__________

promising that it would be multiplied by magic powers; when the peasant returned to

dig them up, the money and the gypsies were both gone. 10.__________

The term “gypsy” soon became synonymous with all the

robbers and brigands who

infested the countryside.
