14. Translate into Russian in writing:

Energy is the capacity for doing work. The various forms of energy, interconvertible by suitable means, include potential, kinetic, electrical, heat, chemical, nuclear, and radiant energy. Interconversion between these forms of energy occurs only in the presence of matter.

In the absence of matter energy can only exist in the form of radiant energy.

 

 

Test

Choose the correct form:

1. The aluminium plant is a (consumer, consumption) of the (local, locally) generated electric power.

2. The (new, newly) built shops are (importance, important) for the future of the power plant.

3. Nuclear energy is energy released during a nuclear (reactor, reaction) as a result of (convertible, conversion) of mass into energy.

4. Uranium is a (comparison, comparable, comparatively) rare element.

5. The most (importance, important) problems in (atom, atomic) power (generator, generation) are connected with the reactor. Reactor (technologist, technology) is still in (progressive, progress). The light-water reactor types seem most (usefulness, usefully, useful).

Конверсия

В отличие от русского языка, в английском языке одно и то же слово может выступать в предложении в качестве разных частей речи. Так, в данных ниже предложениях слово water является существительным (1), глаголом (2), играет роль прилагательного (определения) (3), является частью сложного слова (4).

1. Water is necessary for life. -Воданеобходимадляжизни.

2. Water the flower-bed, please. -Полей(те),пожалуйста, клумбу.

3. Water mills served a source of energy. -Водяные мельницы служили источником энергии.

4. water-supplysystem- система водоснабжения

water-proofwatch- водонепроницаемые часы

Значения подобных слов и их перевод на русский язык зависят от того, каким членом предложения они являются. Они могут быть подлежащим, сказуемым (или его частью), определением, обстоятельством. Функцию слова помогает определить твердый порядок слов в английском предложении и контекст.
