Metals are materials most widely used in industry because of their properties. The study of the production and properties of metals is known as metallurgy.

The separation between the atoms in metals is small, so most metals are dense. The atoms are arranged regularly and can slide over each other. That is why metals are malleable (can be deformed and bent without fracture) and ductile (can be drawn into wire). Metals vary greatly in their properties. For example, lead is soft and can be bent by hand, while iron can only be worked by hammering at red heat.

The regular arrangement of atoms in metals gives them a crystalline structure. Irregular crystals are called grains. The properties of the metals depend on the size, shape, orientation, and composition of these grains. In general, a metal with small grains will be harder and stronger than one with coarse grains.

Heat treatment such as quenching, tempering, or annealing controls the nature of the grains and their size in the metal. Small amounts of other metals (less than 1 per cent) are often added to a pure metal. This is called alloying (легирование) and it changes the grain structure and properties of metals.

All metals can be formed by drawing, rolling, hammering and extrusion, but some require hot-working. Metals are subject to metal fatigue and to creep (the slow increase in length under stress) causing deformation and failure. Both effects are taken into account by engineers when designing, for example, airplanes, gas-turbines, and pressure vessels for high-temperature chemical processes. Metals can be worked using machine-tools such as lathe, milling machine, shaper and grinder.

The ways of working a metal depend on its properties. Many metals can be melted and cast in moulds, but special conditions are required for metals that react with air.

Срочно!Помогите пожалуйста!!! нужен перевод 1 и 3 абзацы ( не по переводчику) . + ответить на вопросы. PUBLIC BEHAVIOR IN THE UNITED

KINGDOM

1. Britons, and the English in particular, are notoriously undemonstrative. The “stuff upper lip” is not just the stuff of fiction and emotional displays, positive or negative, are generally frowned upon. Gestures such as backslapping and hugging are discouraged and a wide distance should be maintained between participants in a conversation. Maintaining eye contact may be necessary when you are trying to emphasize important points but you must avoid any temptation to “eye-ball”. Talking loudly is unacceptable and shouting is beyond the pale. Some old-fashioned interlocutors may not hear you if you have your hands in your pockets. The British do not gesticulate frantically.

2. Introductions can be tricky. Ideally the British prefer third-party introductions but in certain situations, like a drinks party, it may not always be possible and, though awkward, you may just have to go ahead and introduce yourself. Firm handshakes are the norm as part of a formal introduction but may not be expected at subsequent meetings or on social occasions; a gentleman should always wait for a woman to proffer her hand before squeezing it gently. The continental habit of exchanging kisses has gained currency especially amongst the young and the affected but is not recommended for visitors – even the natives are unsure of the correct procedure.

3. “How do you do?” is a greeting not a question. It is used when people are introduced for the first time only and the correct response is to repeat “How do you do?” which is a more or less sincere enquiry as to your well-being.

4. This emotional detachment or even apparent indifference also explains the British abhorrence of Americanisms such as “Have a nice day”. The objection lies not in the sentiment itself but in the lack of sincerity that is implied to the stand-offish British mentality.

5. If the British use few words, it is because they prefer to mean those they do use. They are polite and courteous for the most part. They expect to be treated with respect, in turn for which they will treat you with respect, so: – if there is a queue, go to the back of the line and wait patiently; - do not use the “V” – sign (raising the index and middle fingers) unless you are sure which is the Churchillian version signifying peace or victory (palm outwards); the use of the alternative version (palm inwards) is less common nowadays but is still vulgar and offensive.

6. A service charge of 10-15 % is almost always included in hotel and restaurant bills and you should be wary of establishments that leave the credit card slip open for you to include an additional contribution (if you wish to reward exceptional service give cash directly to the staff). Do not tip bar staff in pubs where there is no table service. Otherwise taxi drivers (especially in London), hairdressers, porters, etc. will expect 10-15 % or a couple of pounds, whichever is the greater.

Ответить на вопросы по тексту THE SYSTEM OF LAW IN OUR COUNTRY Law is а system of rules established by the

state.

The main aim of law is to consolidate and safeguard the social and state system and its economic foundation.

The system of law in our country consists of different branches of law.

Constitutional law is a leading branch of the whole system of law. Its principal source is the country’s Constitution. It deals with social structure, the state system, organization of state power and the legal status of citizens.
Administrative law is closely connected with constitutional law but it deals with legal forms of concrete executive and administrative activity of the government and ministries.

Financial law regulates the budget, taxation, state credits and other spheres of financial activity.

Civil law is connected with relations in the economic sphere of social life, with relations involving property, its distribution and exchange. The right в property is the central institution of civil law.

The rules of labour law include the legislation on the labour of industrial and office workers and matters arising from labour relations.

Criminal law defines the general principles of criminal responsibility, individual types of crimes and punishment applied to criminals. Criminal law takes the form of а criminal code consisting of а general and special part.

OFFICE AUTOMATION
1. Office automation refers to the varied computer machinery and software used to digitally create, collect, store, manipulate, and relay office information needed for accomplishing basic tasks. Raw data storage, electronic transfer, and the management of electronic business information comprise the basic activities of an office automation system. Office automation helps in optimizing or automating existing office procedures.
2. The backbone of office automation is a LAN , which allows users to transmit data, mail and even voice across the network. All office functions, including dictation, typing, filing, copying, fax, Telex, microfilm and records management, telephone and telephone switchboard operations, fall into this category. As office methods evolved to take full advantage of new technologies, there was a corresponding increase in innovations tailor-made to optimize office processes. Office automation was a popular term in the 1970s and 1980s as the desktop computer exploded onto the scene.
3. Advantages are:
1. Office automation can get many tasks accomplished faster.
2. It eliminates the need for a large staff.
3. Less storage is required to store data.
4. Multiple people can update data simultaneously in the event of changes in schedule.
