3 1. Exercise A:Finding out facts Exercise B:Checking facts and ideas Exercise C: Making deductions Exercise D: Word meaning in context Exercise E: Word meaning in context Exercise F: Filling in information Exercise G: Preposition practice

4 1. Exercise A:Finding out facts Answer the questions: 1. What is the main attribute of solar radiation? How does the text characterize solar collectors and why? 2. How is solar radiation related to local atmosphere? 3. Why are hourly radiation values preferred to average monthly information? 2. Exercise B:Checking facts and ideas Check if the following statements are True or False. If they are false, justify and give the right answer. 1. Sufficient sun availability entails abundance and guaranteed performance of a solar thermal system. 2. Path length varies thus influencing solar radiation. 3. Turning the collector so that it continuously faces the sun provides the ultimate solution in collecting the maximum solar radiation. 4. The need for solar radiation and heat is conversely proportional to the actual sunlight. 5. Since solar collectors remain dormant for one-third to two-thirds of the day the system cost reduces. 6. Elaboration of the data offered by hourly radiation values contribute to an accurate system design. 3. Exercise C: Making deductions Finish up the incomplete sentences with information from the text: 1. If solar radiation wasn't characterized by its variability,. 2. Ordinary pollution is so influential. 3. The only availability of solar radiation data.. 4

5 4. Exercise D: Word meaning in context Find words from the text that have the same meaning as the following: 1. affluent, bountiful: route, drive: possible, probable:.. 4. hibernated, asleep:. 5. notably, significantly:.. 6. that can be valued:. 7. Correspondingly:. 8. Acquire: 9. leaning:. 10. precisely: describe roughly:. 5. Exercise E: Word meaning in context Give the opposites for the following words: 1. variability: 2. continuously: 3. increasing: 4. ordinary: 5. generally: 6. Exercise F: Filling in information Complete the following text with the words given, using the right forms for the verbs: utilization; require, compare, tidal, alternative, resources, add, options, renewable, relative. It is useful to.(1) the various. (2) energy sources in terms of the amount of energy available for. (3) and by the degree of sophistication in technology. (4) for their exploitation. In terms of the amount available, the solar energy and nuclear energy. (5) are very large. (6), with the solar option having the. (7) advantage of being. (8). The energy available from oil shale is also quite large. (9) to these sources, the energy available from tar-sands,. (10) and wave energy and geothermal energy is very small. [...] Adopted from Solar Energy, by S. P. Sukhtme 5

6 7. Exercise G: Preposition practice Complete the rest of the text above with the prepositions missing: [...] In terms. (1 ) the sophistication needed, both the possibilities. (2) the nuclear energy option, namely the breeder reactor and nuclear fusion, call. (3) a very light degree of technological sophistication contrast(4), the technologies involved. (5) the exploitation of tar-sands, oil shale, tidal energy and thermal energy arc simpler. The solar energy option is somewhat difficult to classify. Some solar technologies are quite involved. These include the development of photovoltaic cells and applications like the generation of power in space and. (6) earth using the central tower concept. (7)the other hand, many solar technologies like water heading, air heating and drying of products, are simple and can be readily adopted. 6
