Exercise 4. Complete the following statements by choosing the answer

which you think fits best. Why are the other answers unsuitable?

1. That iron was of great importance is shown by an inventory of king’s

possessions because:

a) things made of iron were classed as jewels and valuables.

b) King Edward III wrote about their value himself.

c) things made of iron could be used only by the king.

2. The owners of metal industry got a political influence because:

a) they had much money.

b) the industry grew in importance.

c) people wanted so.

3. The importation into England of any iron or steel goods was prohibited

by Parliament because:

a) it was necessary to develop native industry.

b) the native production stopped.

c) England didn’t need them.

4. The immediate problem confronting the iron manufacturer was:

a) the lack of skills in steel-making.

b) the growing shortage of wood.

c) the establishment of the blast furnaces.

Exercise 5. Give a written Russian translation of the following passages.

1. The chemical process for extracting a metal from its ore is called smelting. Iron ore is heated with limestone and coke, which is mostly made up of carbon. Coke and limestone remove the unwanted parts of the iron ore to leave almost pure iron, which still contains some carbon. Steel is made by removing more carbon and adding other metals.

2. Gold is much softer than copper, so it is easier to hammer into shape. It is not very strong. A gold knife might look very fine but would not have been much use for skinning a bear, so from early times gold became the metal for ornaments. Copper is much harder; it would have been much more difficult for early man to shape; but the finished article was more durable.

3. These metal-workers were masters of the ancient craft of gold-beating, a process by which gold is beaten between skins until it is reduced to a very thin sheet. The Egyptians could produce sheets only one five-thousandth of an inch thick, and used them for gilding wooden statues and for other decorative purposes.

THE NATURE OF ELECTRICITY

     Practical electricity is produced by small atomic particles known as electrons. It is the movement of these particles which produce the effects of heat and light.

     The pressure that forces these atomic particles to move, the effects they encounter opposition and how these forces are controlled are some of the principles of electricity.

Accepted atomic theory states that all matter is electrical in structure. Any object is largely composed of a combination of positive and negative particles of electricity. Electric current will pass through a wire, a body, or along a stream of water. It can be established in some substances more readily than in others, that all matter is composed of electric particles despite some basic differences in materials. The science of electricity then must begin with a study of the structure of matter.

     Matter is defined as any substance which has mass (or weight) and occupies space. This definition should be broad enough to cover all physical objects in the universe. Wood, water, iron, and paper are some examples of matter. Energy is closely related to, but not to be confused with, matter. Energy does not have mass, and it does not occupy space. Heat and light are examples of energy.

The smallest particle of
matter which can be recognized as an original substance was thought to be a
unit called the atom. Recently scientists have found particles even smaller
than atoms, but our theories are still based on the atom. The atom consists of
a nucleus and a cloud of electrons. It is generally agreed that the electrons
are small particles of electricity, which are negative in nature. These
particles orbit the nucleus in much the same fashion that planets orbit a sun.

ELECTRIC CURRENT

The electric current is a quantity of electrons flowing in a circuit per second of time. The unit of measure for current is ampere. If one coulomb passes a point in a circuit per second then the current strength is 1 ampere. The symbol for current is I.

The current which flows along wires consists of moving electrons. The electrons move along the circuit because the e .m. f. drives them. The current is directly proportional to the e. m. f.        

In addition to traveling through solids, however, the electric current can flow through liquids as well and even through gases. In both cases it produces some most important effects to meet industrial requirements.

       Some liquids, such as melted metals for example, conduct current without any change to themselves. Others, called electrolytes, are found to change greatly when the current passes through them.

When the electrons flow in one direction only, the current is known to be d. c., that is, direct current. The simplest source of power for the direct current is a battery, for a battery pushes the electrons in the same direction all the time (i.e., from the negatively charged terminal to the positively charged terminal).

The letters a. c. stand for alternating current. The current under consideration flows first in one direction and then in the opposite one. The a. c. used for power and lighting purposes is assumed to go through 50 cycles in one second. One of the great advantages of a. c. is the ease with which power at low voltage can be changed into an almost similar amount of power at high voltage and vice versa. Hence, on the one hand alternating voltage is increased when it is necessary for long-distance transmission and, on the other hand, one can decrease it to meet industrial requirements as well as to operate various devices at home.

Although there are numerous
cases when d. c. is required, at least 90 per cent of electrical energy to be
generated at present is a. c. In fact, it finds wide  application for lighting,
heating, industrial, and some other purposes.

помогите пожалуйста решить задание по тексту .

Hippocrates was born in Greece. He was the son of a doctor. Hippocrates studied medicine and then went from town to town where he practiced the art of medicine. It is known that he drove out plague from Athens by lighting fires in the streets of the city. That is all we know of Hippocrates himself. But we have his writings which are called Hippocratic Collection. The Collection Consists of more than one hundred books. Some of the Hippocratic thoughts are quite modern. The Collection begins with the famous Oath. Hippocrates was known as an excellent practitioner and a teacher of medicine. This great physician taught his pupils to examine the patient very quick help. He created medicine on the basic of experience. Hippocrates freed medicine from superstition. He hated the idea that a disease was the punishment of goods. Hippocrates paid much attention to diet, gymnastics, and massage, sea-bathing in treatment. He knew the use of many drugs and was also a good surgeon. Hippocrates set fractures and even trephines the skull. Aristotle, the famous philosopher, called him “Hippocrates in Great”.
