5. Exercise 3. Read and learn.

6. Hiking in the Mountains

7. Mike: My steps become lighter because I hear the music of running water. Let's stand and look at the stream.

8. Jane: Why only look? I'm thirsty (хочу пить) and nothing tastes so good as cool mountain water.

9. M.: But passing the same water through the pores of the skin does the body fifteen times as much good as it does when you drink it. Put your hands and arms into the deepest place and keep them for a while and you'll feel so wonderful.

10. J.: I can't stop drinking. Look at the clear, smooth surface of the stream. Water is beautiful.

11. M.: And perhaps, the most beautiful thing about it is its use. It helps all living things in one way or another.

12. J.: I know that my own body is eighty-five per cent water.

13. M.: Yes, and this water keeps you going in spite of the weather.

14. J.: How does it do this?

15. M.: By circulation it keeps your body at the same temperature all the time.

16. J.: I've read that water has the most interesting properties of all liquids. It is the slowest to cool and the slowest to heat.

17. M.: In winter the water in your body keeps you warm by circulat­ing evenly to all parts. In the heat of summer it passes off through the million of pores of your skin. This keeps you cool and takes away toxic material at the same time.

18. 183

5. J.: I think the great supply of water in the body is one of the na­ture's great provisions.

6. M.: Sure, especially taking into consideration (принимать во внимание) that the human being can live only within the nar­row range (диапазон) in body temperature of a very few de­grees Fahrenheit. Have you had enough water?

7. J.: Yes, I have. Usually I drink at least six glassfuls of water daily.

8. Exercise 4. Speak about:

1. An advanced manned submersible.

2. Practical applications of manned submersibles.

5. Use exercises 1, 2 and the following words and word combinations for your topic: to realize a dream, underwater exploration, to penetrate, a submersible vehi­cle, to descend to a depth up to, to perform tasks, collecting samples of minerals and marine life, to work for nine hours, to join efforts.

6. Exercise 5. Comment on the following statement.

7. Scientists cannot afford (позволить себе) to be interested in things not connected with their subject.

8. One point of view: There is no alternative to narrow (узкий) specialization, ev­erybody has a limited amount of time, it is unrealistic to expect a scientist to be in­terested in other fields than his own, a person who is interested in many things is sure to become a dilettante.

9. A contrary point of view : It is impossible to understand a particular science in complete isolation, the scientist should not be treated as a machine for solving spe­cialized problems, a narrow specialist may tend to become a narrow -minded per­son, really great scientists have always had wide interests.

10. What do you think about it? Why?

11. Exercise 6. A. Read and say what you think about tea and what it does for you.

12. Tea

13. The English know how to make tea and what it does for you. Seven cups of it wake you up in the morning; nine cups will put you to sleep at night.

14. If you are hot, tea will cool you off, and if you are cold, it will warm you up.

15. If you take it in the middle of the morning, it will stimulate you for further work; if you drink it in the afternoon, it will relax you for further thought. Then, of course, you drink lots of it in off hours (свободное время).

16. The test of good tea is simple. If a spoon stands in it, then it is strong enough.
