Look at these incomplete sentences from the conversation between Susan and Nick and try to remember who said each one. Write S for Susan and N for Nick. Then listen to the complete sentences and fill in the missing words.
1. On water? Well, I’m working on it right now. …….. ……… …….. ……… the most essential facts.
2. You know what? There’ s something that might be of interest. It’s from a ….. ….. ……
3. Mind you, it’s about …. ….
4. But how does it happens? First, it …. …. ….., lakes, rivers, soil and plants.
5. Wait a tick. Did you say …. …. ….?
6. That’s right. And …. …. …. and ice into the atmosphere.
7. Second. The sun supplies the energy needed for …. …. …..
8. Well. Water then returns to the Earth as …. …. …..
9. You see, you may also write as … … …. if you like.
10. What about energy release by …., ….. and ….?
11. 9 Listen to the dialogue for the third time if necessary and answer the following questions.
1. What article is Nick writing?
2. What information does Susan give to Nick?
3. What are the forms of water that Susan names?
4. What figures does Susan cite?
5. When will Nick’s article go to press?
12. Discussion- You have to give a lecture on “Hydrologic cycle”. Use the keys and diagram.
Keys:
1. Atmospheric water in circulation
2. Formation of storm clouds
3. Precipitation (snow, rain, hail, etc.)
4. Evaporation of precipitation in transit and moisture diffusion
5. Net precipitation on Earth surface
6. Snow storage and melt
7. Infiltration
8. Deep percolation
9. Ground –water flow and storage
10. Overland flow and depression
11. Evaporation of intercepted and surface water
12. Evapotranspiration
13. Surface storage in lakes and reservoirs
14. Evaporation from lake surfaces
15. Surface streams
16. Evaporation from streams
17. Ground-water exchange from channel storage (base flow and return)
18. Ground-water exchange from channel storage (base flow and return)
19. Ground-water flow to ocean
20. Ground-water flow to ocean
21. Storage in the ocean
22. Evaporation from ocean surfaces

13. Now look at the keys for 45 seconds, try to remember the terms. Close your course book and write down the words. Be honest! The person who has more words is the winner.
14. Look at the schematic illustration of the hydrologic cycle for 30 seconds and then try to draw it. Afterwards ask your partner to describe it.

15. Work in groups and discuss your opinions. Can your group reach an agreement? Read the quotation of the famous hydrogeologist B.L.Lichkov and share your ideas.
“The circulation of natural water on the planet, although not as yet completely understood, must be recognized by all as critically significant for hydrogeology, and for the land areas; the primary significance must be given to their moisture content. Thus, a new hydrogeology must be constructed on three principles – the unity of water, its circulation, and the moisture content of the land. In a word, the circulation of water is one of the cornerstones of modern hydrogeology”
(B.L.Lichkiov)
STAGE 1 – group work responding to problem discussion. During these stage, each group will discuss the problem separately.
STAGE 2 – sharing ideas of response to the problem. One person from each group should move to another; so that each group has a member with different information. Now the members of each new group share their ideas.
STAGE 3 – now each of you should jot down all the information you remember.
§ Jig-saw plan (1-2 minute) short one-point talk
§ Multi-point conversation (5 minutes)
16. Now prepare a presentation “The Hydrological Cycle” for the Student Science Conference. The following plan and phrases will help you.
Plan
1. Plan and carry out your presentation.
2. Define the subject of your presentation.
3. Think of the introduction of your presentation.
4. Try to anticipate questions during the preparation of your presentation.
