【文章內(nèi)容簡介】 wable energy sources. The history of the use of different energy sources. □ How energy is obtained from various sources. 3) I would write: (1) The definition of the renewable energy. (2) The classification of the renewable energy. (3) The advantages and the disadvantages of various types of renewable energy sources. 2. 1) The signing of the Kyoto Treaty. 2) It converts the sun’s rays into energy. 3) The main demerit is that it is limited. 4) Sailors, farmers and architects. 5) The main advantage is that this doesn’t produce any byproducts that can be harmful to the environment. 6) Because the Earth’s crust continuously decays, replenishing the heat. 7) They use the force of the water to push the turbine which in turn powers a generator thus generating electricity. 8) It poses a problem for fish and aquatic plants on both sides of the dam. 9) They contain no petroleum, and they are nontoxic and biodegradable.10) The Environmental Protection Agency. 3. 1) j. evolution 2) s. solar 3) a. architect 4) l. geothermal 5) p. preserve 6) b. biodegradable 7) r. radioactive 8) f. crusade 9) h. distribute 10) q. radiant 11) i. domestic 12) t. validation 13) k. generator 14) d. capture 15) g. definitely 16) n. install 17) e. consumption 18) m. harness 19) o. internal 20) c. blade Reading 3 Types of Pollution 5. 1) voluntary 2) construction 3) contamination 4) eruption 5) regulation 6) deforestation 7) yield 8) irrigation 9) confine 10) sewage 11) hazardous 12) residential 13) vapor 14) decay 15) erosion 16) disrupt 17) particulate 18) underground 19) concentration 20) bat 6.

ParagraphsMain ideas(_t_) Para. Yy. Definition of soil pollution.(_r_) Para. Zz. Sources of air pollution.7. Paragraphs(Marked I, or E or F)StatementsPara. Z1) A knowledge of different pollution types enables a person to change his lifestyle.E2) Thermal pollution is caused by too much heat which creates unfavorable effects over a long time.Para. D3) If the air is filled with a high concentration of pollutants, it would lead to obvious problems.Para. L4) Noise pollution may lead to deafness or interrupt the normal life of wild animals.Para. E5) Water pollution may result in an insufficient supply of drinkable water.F6) Since visual pollution causes few immediate health effects, it is not serious at all.Para. H7) Soil pollution may be both intended and unintended.E8) Over smoking and drinking belongs to personal pollution.8. My summary is: Even if solar energy is limited, it enjoys a long history and has been advancing constantly, thus enabling us to convert heat into electricity, which can be stored, ready for use. Task 4 Writing an Essay of Classification Reading 4 Types of Sustainability 1. PartsParagraphsMain ideasSupporting detailsIAClassification of sustainability: human, economic, social, and environmental.It is vital to understand the differences of each in terms of its nature and requirements.IIBDefinition of human sustainability: good productive health and safe childbearing. Elements involved: For parents: caring for their children, giving them access to proper education, and promoting their health and wellbeing. For children: having enough skills and knowledge. CDefinition of economic sustainability: having a set amount of capital for a certain period.Explanation ( relation between preservation and consumption): We must preserve all our sources as we consume them.DWhy social capital is important: It is through munities and civil societies that humankind can easily and inexpensively work together.Explanation (how to achieve it): Through proper maintenance of and adherence to laws, rules, and values that societies have developed for the mon good, social sustainability can be achieved.E—FWhy environmental sustainability is important: It involves natural resources that human beings need for economic or manufactured capital.Elements involved: Natural resources: Materials taken from nature are used for solutions that address human needs. Waste emissions: They must be at volumes that nature can handle.5. 1) Declarative sentences are mostly employed in academic writing, despite the occasional utilizations of interrogative sentences. 2) To support the truths, reliable evidence is quoted by scholars in all disciplines. 3) Much importance should be attached to the prehension of the difference between education and training. 4) A person who exposes himself to the sunlight for excessive time is susceptible to malignant melano
