Minsk is my native town. It is the capital of the Republic of Belarus and I am proud to be its citizen. Minsk is an ancient town with a rich history.
More than 2000 years ago on the banks of the Nemiga and Svisloch rivers came into existence the city of Minsk or Mensk as it was called before.The name of the city is believed to be associated with the river Menka that flowed into the lake Ptich not far from the city. But the legends say that the city derives its name from the word "mena" as in the ancient times there was a barter market on the right bank of the river Svisloch. Mensk was first mentioned in chronicles in 1067. In the 12th century Mensk became the center of the independent Polotsk principality. In the late 13th century the principality became part of the Great Duchy of Lithuania.
The 14th -15th centuries were very important in the life of Mensk and its inhabitants. It was the period when the Belarusian nation was formed with its national language and culture. In the middle оf the 16th century the Lithuanian Princes united with the Polish Kingdom and formed a united state Rzecz Pospolita. It was at that period when Mensk was renamed into Minsk. Till the 18th century the Belarusian people were vassals to Polish feudal lords who exploited them cruelly.
In the 18th century (1793) Belarus was annexed by Russia and was turned into a province with Minsk as its center. In 1812 the Napoleon troops burnt the city almost to ashes. In the 20th century the Belarusian capital underwent not once foreign occupation: in 1918 it was occupied by Germany; in 1919-1920 by Poland.
During the Great Patriotic War our capital was almost completely destroyed by the fascist invaders. We can say that in the post-war years it was rebuilt anew to become even more beautiful.
At present Minsk is the capital of the Republic of Belarus which is an independent state with its own state symbols, Parliament and President. It is a big developing city with the population of about 2 million. It occupies the territory of 200 square kilometers.
Every visitor of our city admires its beautiful buildings, wide streets and avenues, green parks and monuments. Minsk is also a big traffic center with a wide network of roads, railways, airlines and two Metro lines.
Minsk is the major industrial and cultural center and one of the most beautiful cities. The city has acquired its peculiar look and colouring thanks to the well-planned avenues and squares, to the green of the parks and gardens stretching along the Svisloch river, to its historical monuments.
There are hundreds of plants and factories in the city which produce various goods. Tractors and lorries, motorcycles and bicycles, TV-sets and watches, refrigerators and computers, textile and footwear are manufactured here. Our Belarus tractors and MAZ trucks enjoy a high reputation both in our country and abroad.
Minsk is also known as a city of science and students. There are many state and non-state institutions of education which train specialists in different fields of economy and social life.
The cultural life of the Belarusian capital is varied and very interesting. In Minsk there are many museums and exhibitions, theatres and concert halls, cinemas and libraries, clubs and concert halls. Among the theatres it is worth mentioning the National Academic Bolshoi Theatre of Opera and Ballet, the Yanka Kupala State Academic Theatre, and the Gorky State Russian Drama Theatre which are extremely popular with the public.
Minsk is a Hero-City. It was honoured with this title in 1974 for the courage and heroism displayed by its inhabitants during World War II.
Minsk today is a city with broad possibilities for development. Embassies, banks, business centers, public and private institutions, offices have been springing out in the city. Minsk is attractive and very romantic in all seasons of the year. This special city is beloved by its inhabitants and by all Belarusians.

Reproduction and Growth
Reproduction of bacteria is usually by fission: an individual cell enlarges and splits into two, each of the resulting pair being an exact replica of the parent cell (in the absence of mutation). Filamentous species reproduce by the elongation and branching of their filaments. A few bacteria multiply by a budding process. Methods of reproduction are almost invariably asexual, though a form of ‘sexual’ mating has been rarely observed.
In the laboratory most bacteria can be induced to ‘grow’ (reproduce) in liquid or on solid culture media. Nutrient requirements, atmospheric conditions correct pH value (acidity or alkalinity) of the medium, osmotic pressures and temperatures are rendered optimum for the multiplication of species in vitro. Some bacteria will grow in a simple defined medium consisting of a few salts in aqueous solution (trace elements are provided by the impurities found in all chemicals, even those described as ‘pure’). Others, including many pathogenic species, require protein degradation products, such as digested meat, in the constitution of media suitable for their growth. Some fastidious pathogens need media enriched with blood or other highly nutritious substances.
Say whether the following statements are true or false:
1. Methods of reproduction of bacteria are mainly asexual.
2. Bacteria never multiply by budding.
3. Bacteria usually reproduce by dividing into numerous parts.
4. Bacteria can’t be grown in the laboratory.
5. Numerous requirements have to be met in order to make bacteria reproduce in vitro.
6. The medium enriched with nutritious substances is required for some pathogenic bacteria.
T E X T B
Bacteria: their Construction
Bacteria are very small single-celled organisms (microorganisms) that exist in enormous numbers almost everywhere. They live in soil, water, air, and in living and dead animals and plants. A gram of soil can contain up to a thousand million bacteria, and there may be hundreds of thousands in a single drop of milk.
Bacteria differ from each other mainly in where and on what they live, and in the shape of their single cells. There are the spherical coccus types such as Staphylococcus and Streptococcus, which often occur in chains or masses, and the rod-shaped bacillus type such as Mycobacterium, which causes tuberculosis. Other disease-causing bacteria are Eberthella typhi (typhoid), and Vibrio cholerae (cholera). The type of bacterium which forms a coil or spiral is Spirillum.
Although bacteria cells are more complicated than viruses they are still very simple. Their structure has been worked out with optical microscopes which magnify by one hundred thousand times. All bacteria have a tough outer cell wall so their food must be soluble before it can be absorbed into the cell. In some bacteria there is a protecting layer of jelly enclosing the cell wall, and also one or more minute fibres (flagella) used for swimming. Inside the cell there is a coil of DNA and other chemical substances, but there is no definite nucleus or any of the other structures found in plant and animal cells.
Bacteria usually reproduce by simply splitting in two. When temperature conditions are favourable, about 37°C for most bacteria, they can divide about оncе every 30 minutes. In theory, one bacterium could form about 140 000 000 000 000 bacteria at the end of 24 hours. In fact, this does not happen because the supply of food soon runs out, poisonous wastes accumulate, and after a time no more bacteria can survive. Although most bacteria reproduce by dividing in two, some bacteria can reproduce sexually, during which the contents of one bacterium flow into another.
Bacteria are very tough. Different kinds can live in almost every environment, from hot springs to arctic frost. Many can form a type of spore under certain conditions. A spore is capsule inside which a bacterium can survive for years of drying out, intense heat or disinfectant. Few of disease bacteria can make spores.

The United Kingdom
The United Kingdom of Great Britain and Northern Ireland is situated on the British Isles comprising 2 large islands, Great Britain and Ireland, and a number of smaller islands washed by the North sea, the Irish sea, the English Channel and the Atlantic Ocean. Its territory is about 244,000 square kilometers; the population is about 57 million people.
When we speak about the U.K. we actually speak about 4 countries united into one state: England, Scotland, Wales and Northern Ireland. Each of these countries has its own language, its capital, its government. The capital of Scotland is Edinburgh, the capital of Wales is Cardiff, the capital of Northern Ireland is Belfast, the capital of England is London. London is the capital of the United Kingdom as well. English is the official language but a lot of people know more than one language: Welsh, Gaelic, Irish.
The surface of England and Ireland in rather flat, the highlands are in Scotland and most of Wales. The highest mountain in Scotland is Ben Nevis (1,343m high) and the highest mountain in Wales is Snowdon (1,085m high). The main rivers are the Severn, the Clyde, the Thames.
The climate is moderate and mild due to the influence of the warm waters of the Gulf Stream. There is a lot of rain in autumn and winter.
The U.K. is a highly developed industrial state. Britain is a major supplier of machinery, aerospace products, chemicals, electric equipment and a growing oil exporter. Nowadays an important part of foreign trade is so called “invisible” export: insurance, aviation, scientific and technical expertise, tourism, financial services. The biggest industrial centres are London, Glasgow, Liverpool, Sheffield, Birmingham, Manchester.
The United Kingdom is a parliamentary monarchy. Her Majesty Queen Elizabeth II (the second) is considered to be the head of the state, with a largely ceremonial role.
The legislative power belongs to the Parliament which consists of two Houses. The House of Lords is composed of hereditary, life and spiritual peers and peeresses. The members of the House of Commons are elected by the people. The executive power is exercised by the Prime Minister and his Cabinet.
There are three main political parties in the U.K.: the Labour, the Conservative (the Tories) and the Liberal-Democratic Parties. The Labour Party with David Cameron at the head is the ruling party nowadays. There is no written constitution in the U.K., only precedents and traditions.
The inhabitants of the U.K. are famous for their customs and traditions.
British people are naturally polite: they are never tired of saying “Thank you” and “I’m sorry”.
They are generally disciplined; they never talk aloud in the street; they never show their emotions even in tragic situations; they seem to remain good-tempered and cheerful under difficulties.
The most famous educational centres are Oxford and Cambridge universities. They are considered to be the intellectual centres of Europe.
