19.Переведите текст. В каждом предложении найдите сказуемое, определите его время и залог.
Chemistry is the science of substances — of their structure, their properties and their reactions that change them into other substances. This is a very large field of study because the number of different kinds of substances is very great, and each kind has its own characteristic qualities. Chemistry occupies a central position among the basic sciences. It is closely connected with physics and biology. It plays an important part in the development of geology and physiology, and enters every industry as well as medicine and agriculture.
The early chemists studied two types of matter: inorganic and organic. But the materials which are provided by nature cannot satisfy modern science and technology now and man is turning more and more the help of chemistry.
In present-day organic chemistry new compounds are being synthesized daily. With its plastics, synthetic fibres and other artificial materials organic chemistry is the chemistry of modem times. Inorganic chemistry quite a different thing, it was studied long ago and is as old as the Old World.
Chemical science is successfully solving many complex problems and its rapid development will be raising the living standard of people.

TEXT В. PHOTOGRAPHIC MATERIALS INSENSITIVE ТО LIGHT
В настоящее время много серебра обрабатывается, чтобы произвести светочувствительные материалы. Много серебра входит в электрическую разработку и электронику. Много экспертов в мире ищут замены для серебра. Недавно группа исследователей из Белоруссии развила фотографические материалы, чувствительные к ультрафиолетовому излучению, которые не содержат серебра.
У этих материалов под названием Foban и Fotban есть большая власть решения. Каждый квадратный микрон содержит больше чем 600 светочувствительных пятнышек. Они - хорошие замены для фото материалов, которые обычно используются в процессах, где высокая светочувствительность не важна. Foban очень превосходит содержащие серебро материалы. Это произведено из полимера, который способен, чтобы сформировать изображения, если они выставлены ультрафиолетовому radiatoin. Материалы Foban могут быть сохранены в течение фактически неограниченного времени. Газета Foban и фильм могут быть произведены на оборудовании в полном свете.
Каково различие между Фобэном и Фотбэном? Они - почти то же самое. Письмо "t" в Фотбэне показывает, что имеет некоторое отношение к текстилю, в то время как Foban используется в фильмах и газете. Фотбэн может быть легко окрашен во многих цветах и не поднимает статическое электричество.
23. Закончите предложения в соответствии с содержанием текста:
7. Foban and Fotban are produced from...
a) silver; b) photo materials; c) polymer materials.
8. Foban and Fotban...
8. have absolutely different properties;
9. are nearly the same.
9. Foban and Fotban are used in processes where...
4. high light sensitivity is not important;
5. high light sensitivity is very important.
*24. В соответствии с содержанием текста выберите характеристики, относящиеся к:
1) Fobana) can be produced in full light;
2) Fotbanb) is used in textiles;
3) Fobanand Fotban c) is used in films and paper;
d) can be stored for unlimited time;
e) are good substitutes for photo materials;
f) can be easily dyed in any colour;
