1. прочтите и переведите письменно на язык следующий текст. the greenhouse effect much is written about the tendency of the earth's temperature to rise and the "greenhouse effect" that would begin to alter the earth's climate by the end of the 1990s. in faсt, the science of the phenomenon is more interesting than frightening. "the greenhouse effect” results when co2 and certain other gases in the atmosphere allow the sun's ultraviolet rays to penetrate and warm the earth but then absorb the infrared energy the earth radiates back into space – much as glass in a greenhouse effect does – forming a kind of "thermal blanket" around the planet. burning huge amounts of fossil fields, which release co2 into the atmosphere, man has raised the co2 level from 280 to 340 parts per million since 1860 and continued use of coal and other fossil fuels is expected to double the concentration of the co2 by the year 2050, elevating, the earth's temperature by 3 to 9 degrees fahrenheit. the greenhouse effect will mean much more than hotter summers and milder winters. it may alter rainfall, affect crop yields and eventually, as glaciers begin to melt raise the level of the sea. the temperature change is reported to be greater in the polar regions than near the equator. in general, it is said that snowfall will begin later, the growing season will lengthen and higher latitudes will get less rain. if we can't prevent the greenhouse effect, we can prepare for it. suggestions include breeding plants that need lees water, improving irrigation systems and many others. however, not all experts are convinced that the heat is coming. some think that the use of primary energy sources such as coal could decline 60 per cent by 2050 and, perhaps, if the rate of fossil – fuel use is going down, the amount of co2 is getting less every year. 2. переведите вопросы на язык и ответьте на них. 1. what is the "greenhouse effect"? 2. what happens in polar regions? 3. what is the role of fossil-fuels in the “greenhouse effect"? 3. переведите предложения на язык, используя текст. 1. давайте изучим явление, которое называется “парниковым эффектом".. 2. мы должны быть готовы к тому, что температура земли может измениться 3. говорят, что "парниковый эффект” может изменить климат земли.
