VI. Read and translate word combinations consisting of two or more components. See model. Read and translate the sentences from the text containing these word combinations.

a) Model: energy usage использование энергии

material body, pulley system, energy sources

b) Model: used technology – использованная технология

above-mentioned example, limited application, raised position

VII. Answer the following questions.

  1. What does the term “energy” mean?

  2. What is a physical sense of energy?

  3. Who mentioned the idea of energy for the first time?

  4. How did Galileo describe it?

  5. Are there various types of energy?

  6. Is potential energy the energy of motion?

  7. Can one form of energy be transformed into another?

  8. Is the energy of falling water employed to drive turbines?

  9. Does a generator produce mechanical energy?

  10. For what purpose do people apply the sources of energy?

  11. Why are the energy sources decreasing?

  12. Is the Sun an unlimited source of energy?

  13. Did scientists turn solar energy into electric one?

  14. Can we employ solar energy directly?

VIII. Are the sentences True or False? Correct the false sentences.

  1. We possess the unlimited sources of energy, and among them solar energy plays an important role in modern civilization.

  2. Galileo proved with the help of pulley system, that energy expended is equal to work done.

  3. Waterfall demonstrates us that one form of energy can be reversed into another, namely, potential energy can be transformed into kinetic.

  4. Every kind of energy is applied to generate the electric current.

  5. Any modern enterprise can avoid using electrical energy, because there are many new technologies which allow employing solar energy in big quantities.

IX. Look through the text again. Give the main points of each passage of the text. Use: “deals with” + word combinations given below.

Model: The first (second, third, fourth…) passage of the text deals

with… .

disadvantages of solar energy usage, changing potential energy into kinetic, the term applied to energy and physical sense of it, possibilities of solar energy, various forms of energy, increasing need of energy
