ACID RAINS
Every year more and more plants and animals disappear never to be seen
again. Strangely, it is the most intelligent but most thoughtless animal that is
causing most of the problems — man. Nature is very carefully balanced and if
this balance is disturbed, animals can disappear alarmingly fast. Every day,
thousands of species of animals draw closer to extinction. There are countless
number of species which may become extinct before they are even discovered.
In many lakes the fish are dying. Fishermen are worried because every year there
are fewer fish and some lakes have no fish at all. Scientists are beginning to get
worried too. What is killing the fish?
The problem is acid rain. Acid rain is a kind of air pollution. It is caused by
factories that burn coal or oil or gas. These factories send smoke high into the
air. The wind often carries the smoke far from the factories. Some of the
harmful substances in the smoke may come down with the rain hundreds of
miles away.
The rain in many places isn't natural and clean any more. It's full of acid
chemicals. When it falls in lakes, it changes them too. The lakes become more
acidic. Acid water is like vinegar or lemon juice. It hurts when it gets in your
eyes. It also kills the plants and animals that usually live in lake water. That is
why the fish are dying in lakes.
But dead fish may be just the beginning of the problem. Scientists are finding
other effects of acid rain. In some large areas trees are dying. Not just one tree
here and there, but whole forests. At first scientists couldn't understand why.
There were no bugs or diseases in these trees. The weather was not dry. But
now they think that the rain was the cause. Acid rain is making the earth more
acidic in these areas. Some kinds of trees cannot live in the soil that is very
acidic.
Now scientists are also beginning to study the effects of acid rain on larger
animals. For example, they believe that some deer in Poland are less healthy
because of acid rain. If deer are hurt by the rain, what about people? This is the
question many people are beginning to ask. No one knows the answer yet. But
it is an important question for us all.

Marketing Department is run by Frank Peters. He was appointed the Sales Manager a year ago. He hopes he will be promoted next year. The factory is completely different now. It has been modernized and computerized and a lot of people have been made redundant. I couldn’t use the company car because it was being repaired.

PHYSICAL AND CHEMICAL CHANGESTransformations are of two kinds, known as physical and chemical changes.Physical changes are those which effect the state or condition of matter withoutchanging its composition. There is no change in the composition of a substancewhen it is transformed from the liquid to the gaseous state by heating, or from theliquid to the solid state by cooling, and vice versa. Thus, in all three states, stream,water, and ice are all the same substance, made up of the simpler substances,hydrogen and oxygen. The state, but not the composition is effected by the process ofheating or cooling.By changes in the conditions of a substance are meant changes such as when asolid mass is made to fine powder, salt or sugar are dissolved in water. It is clear thatsuch transformations like the changes from one state of matter to another, do notaffect the composition of the material. The fine power of a substance may be madesolid again, and we get back the sail or sugar unchanged by evaporating the water.Chemical changes, however, are those matter changes in which changes ofcomposition does take place and the new substance formed will not return to itsoriginal state, unless it is subjected to another chemical change. Thus iron, when it iseffected by moist a ir, is slowly transformed into iron rust entirely different in itsproperties from the original iron. The new substances will not become iron againwhen it is allowed to stand, although the iron can be obtained from it if it issubjected to the proper conditions

Considerable attention in the Soviet space programme is paid to
researches aimed at solving problems for national science and
economy. A great deal of scientific- technical and medical-
biological experiments have been carried out. Numerous data
concerning the earth' s national resources, the atmosphere and
seasonal changes are gathered. Biological experiments with the aim
of developing the technology of growing plants in space conditions
are continued. These experiments and data are of great practical
importance.

In England about 93 per cent of children attend state schools. The other 7 per cent attend private schools. A minority of these private schools are boarding schools where children live as well as study. Private schools are very expensive.
In Britain it is compulsory between the ages of 5 and 16 years to receive some officially recognized form of schooling. For younger children, there are a few state kindergartens, some private kindergartens and a few „ nursery classes "in ordinary schools. They are optional. Primary school consists of a reception class, infant school and junior school. A reception class and infant school take a year. In junior school, pupils spend 5 years. At the age of five they go to infant schools where they learn first steps in reading, writing and using numbers.
When children leave infant school, at the age of seven, they go to junior schools until they are about eleven years of age. Their school subjects include English, arithmetic, history, geography, na-ture study, swimming, music, art and organized games.
At about 11 or 12 children move to a new school, ussualy a "comprehensive" that accepts all the children from theree or four neighbouring junior schools. Changigng to the "big" school is a great moment in life for them. At secondary school pupils study for 5 years. Comprehensive schools want to develop the talents of each individual child. So they offer a wide choice of subjects, from art and craft, woodwork and domestic science to modern languages, computer studies. There are no entrance examinations, all pupils move automatically to the next form at the end of the year.
There are some grammar schools in which children have to pass a selection test to get in. The grammar school is a secondary school taking about 3 per cent of children pffering a full theoretical secondary education and students can choose which subjects and languages they wish to study. Pupils leave school at 16 and there are several opportunities to continue their studies elsewhere.
