Ann: A distinguishing feature of our time is the unprecedented speed of technology development based upon outstanding scientific achievements.

Pete: Indeed. For thousands of years people led a primitive way of life and then in a comparatively short period of time a gigantic leap has been made in the scientific and technical progress.

Ann; I also thought of how much had been done by the people to reach the present state of the development of human society.

Pete: While the 19th century was mainly the century of steam, the first half of the 20th century was the century of electricity. Now it is increasingly becoming the century of atomic power.

Ann: Yes, Pete, many scientists investigated electric phenomena, and during the 19th century many discoveries about the nature of electricity and of magnetism, which is closely related to electricity, were made. Our life nowadays is revolving around electricity and its many uses.

Pete: Right you are, Ann, we have come to take it for granted. Much had been done by scientists, engineers, workers in producing electricity.

Ann: The present generation knows much about electricity. We now define electricity using the atomic theory. Any matter is made up of atoms. They contain electrons. Their movement in one direction from atom to atom produces electric current.

Pete: It is precisely so. But it is not so simple, as it seems, to generate this current. The common processes of generation of electricity are very uneconomic. To generate electricity it is necessary to get energy and then convert it into electricity.

Ann: And the chief source of energy is heat. So, the common processes of generation of electricity are multistaged ones.

Pete: Yes, Ann. Not direct and with big losses.

Ann: And what about direct methods of electricity generation? Do our scientists work at this problem?

Pete: Yes, they do work. Certain results have already been achieved.

A n n: Do you mean the plasma generator?

Pete: Yes, Ann, I do.


Answer the following question. Your answer should contain 10 sentences. ("What had Pete and Ann talked about?") 3. You will find 7 instances of the usage of the -ed forms in the dialogue. Find all of them and define theii functions. They may be used to form the tense and the voice of a verb. They may be used as modifiers.

The nature of electricity

The ancient Greeks knew that when a piece of amber is rubbed with wool or fur it achieves the power of attracting light objects. Later on the phenomenon was studied, and the word electric, after the Greek word "electron", meaning amber was used. Many scientists investigated electric phenomena, and during the nineteenth century many discoveries about the nature of electricity, and of magnetism, which is closely related to electricity, were made. It was found that if a sealing-wax rod is rubbed with a woolen cloth, and a rod of glass is rubbed with a silken cloth an electric spark will pass between the sealing-wax rod and the glass rod when they are brought near one another. Moreover, it was found that a force of attraction operates between them. An electrified sealing-wax is repelled, however, by a wax rod, and also an electrified glass rod is repelled, by a similar glass rod.

The ideas were developed that there are two kinds of electricity, which were called resinous electricity, and that opposite kinds of electricity attract one another, whereas similar kinds repel one another.


it achives the power вона набуває здібностей sealing-wax rod — паличка із сургуча

after the Greek word —від грецького слова

a rod of glass — скляна паличка

moreover — більше того
