Задание3 Выписать междометия .
Междометия в произведении А.С.Пушкина «Дубровский».
-Здорово, как бишь тебя зовут, - сказал Троекуров.
-Эх, барин, слышали так и мы.
-Ах, батюшка Владимир Андреевич, - отвечал старик, задыхаясь.
-Ах, Владимир Андреевич, это вы, - отвечал Архип пошепту.
-Господь помилуй и спаси!
-Ахти, - жалобно закричала Егоровна.
-Молчи! - сказал Дубровский.
-Эге! – прервал Кирилла Петрович.
-Эк, беда, ты, мусье, по-русски еще не выучился.
-Эх, братец, - прервал Кирилла Петрович.
-Здравствуй, Саша, - сказала она.
-Гей, привести сюда мальчишку пойманного.
-Слава Богу, это исправник.
-Слава Богу, ваше превосходство.

Read the text about materials for construction. Write out the materials, determine their types and complete the table with their physical and mechanical properties.

Modern Building Materials.

Some of the most important building materials are: timber, brick, stone, concrete, metal, plastics and glass.
Timber is provided by different kinds of trees. Timbers used for building purposes are divided into two groups called softwoods and hardwoods. Timber is at present not so much used in building con-struction, as in railway engineering, in mining and in the chemical industry where it provides a number of valuable materials.
However, timber is still employed as a building material in the form of boards. For the interior of buildings plywood and veneer serve a number of purposes.
A brick is best described as a "building unit". It may be made of clay by moulding and baking in kilns, of concrete, of mortar or of a composition of sawdust and other materials.
There exists variety of bricks for different purposes: ordinary, hollow or porous, lightweight, multicolour bricks for decorative pur¬poses, etc. Bricks are usually laid in place with the help of mortar.
Metals: Aluminium, principally in the form of various alloys, is highly valued for its durability and especially for its light weight, while brass is frequently used for decorative purposes in facing.
Steel finds its use in corrugated sheets for roofing, for girders, frames, etc. Various shapes are employed in construction.
Plastics are artificial materials used in construction work for a vast number of purposes. Nowadays plastics, which are artificial materials, can be applied to almost every branch of building, from the laying of foundation to the final coat of paint. Plastics have some good ad¬vantages as they are lighter than metals, not subject to corrosion, and they can be easier machined. Besides, they are inflammable, they can take any colour and pattern, and they are good electrical insulators. More over, they possess a high resistance to chemical action.
A lot of decorative plastics, now available, have brought about a revolution in interior and exterior design. But plastics are used now not only for decoration. These materials are sufficiently rigid to stand on their own without any support. They can be worked with ordinary builders' tools.
Laminate is a strong material manufactured from many layers of paper or textile impregnated with thermosetting resins. This sandwich is then pressed and subjected to heat. Laminate has been developed for both inside and outside use. It resists severe weather condi¬tions for more than ten years without serious deformation. As a struc¬tural material it is recommended for exterior work. Being used for surfacing, laminate gives the tough surface.
Foamed glass is a high–porosity heat insulating material, avail¬able in block made of fine–ground glass and a frothing agent.
Foamed glass is widely used in prefabricated house building, to ensure heat insulation of exterior wall panels, and in industrial con¬struction.
Foamed glass has a high mechanical strength, is distinguished by moisture, vapour and gas. It is non-inflammable, offers resistance to frost, possesses a high sound adsorption, and it is easily sewn and nailed.
Structural foamed glass blocks designed to fill ceilings, and for making interior partitions in buildings and rooms, to ensure heat and sound insulation.
