Unit 8 Focus on Global WarmingKey to the ExercisesText comprehensionI.AII.1. T;2. T;3. F;4. F;5. F.III.1. Paragraph2. Because global warming may be the single largest threat to our planet（the earth）. Low-lying nations could be awash in seawater, rain and drought patterns across the world could change, hurricanes could become more frequent, and El Ninos could become more intense.2. Paragraph3. Our factories, power plants, and cars burn coal and gasoline and spit out carbon dioxide, produce methane by allowing our trash to decompose in landfills and by breeding large herds of methane-belching cattle, and release nitrogen oxide by using nitrogen-based fertilizers.3. Paragraph4. The increased concentrations of greenhouse gases prevent additional thermal radiation from leaving the Earth, so cause the global warming.4. Paragraph 7. A slight increase in heat and rain in equatorial regions would increase vector-borne diseases such as malaria; more intense rains and hurricanes could cause more severe flooding and more deaths in coastal regions and along riverbeds; even a moderate rise in sea level could threaten the low-lying islands; hotter summers could lead to more cases of heatstroke, hospital admissions and deaths among vulnerable people with heart problems or respiratory problems.5. Paragraph 8 and 10. We can curb our consumption of fossil fuels and use technologies to reduce the emission of heat-trapping gases like carbon dioxide, methane, and nitrous oxides, and protect the forests in the world, and we can also advocate policies that will combat global warming over the long term, things like clean cars, environmentally responsible renewable energy technologies, and stopping the clear-cutting of valuable forests.IV.1. Global warming will probably be the most serious threat to our Earth, if we do not take into account of some other possible disasters, such as another world war, collision of our Earth with some small orbiting planet, or spread of incurable diseases.2. In terms of human health, the people of the poorer countries will suffer most, because their countries do not have money to protect them when climate changes.Structural analysisSub-ideas in the second part:1) the causes of the rising concentration of greenhouse gases in the atmosphere (Paragraphs 3 and 4)2) the effect of such concentration on climate change (Paragraphs 5 and 6)3) the potential threat of global warming to human health and survival (Paragraph 7)VocabularyI.

A Fable For TomorrowThere was once a town In the heart of America where all life seemed to live in harmony with its surroundings. The town lay in the midst of a checkerboard of prosperous farms, with fields of grain and hillsides of orchards where, in spring, white clouds of bloom drifted above the green fields. In autumn, oak and maple and birch set up a blaze of colour that flamed and flickered across a backdrop of pines. Then foxes barked in the hills and deer silently crossed the field, half hidden in the mists of the autumn mornings.明天的寓言从前在美国中心有一个小镇，那里的万物看上去都与其四周的环境融洽相处。

小镇的四周是像棋盘交错的兴旺的农庄，还有一块块的田地和一座座遍布山坡的果园。

春天来了，白色的鲜花云彩般地漂浮在绿色的田野上；秋天到了，橡树、枫树和桦树色彩斑斓，在一片松树林间火焰般地燃烧与跳跃。

小山上狐狸吠叫，田野间小鹿静静地跃过，所有的一切都在秋天清晨的薄雾中半隐半现。

Along the roads, laurel, viburnum and alder, great ferns and wild flowers, delighted the traveler’s eye through much of the year. Even in winter the roadsides were places of beauty, where countless birds came to feed on the berries and on the seed heads of the dried weeds rising above the snow. The countryside was, in fact, famous for the abundance and variety of its bird life, and when the flood of migrants was pouring through in spring and autumn people travelled from great distances to observe them. Others came to fish the streams, which flowed clear and cold out of the hills and contained shady pools where trout lay. So it had been from the days many years ago when the first settlers raised their houses, sank their wells and built their barns.在路的两旁，一年中许多时候，月桂树、荚莲、桤木、蕨类植物和各样的野花都能让过往的行人赏心悦目。

The magazine wanted to show some of the heroic work of the firefighters as they battled the blaze.When the photographer arrived, he realized that the smoke was so thick that it would make it impossible for him to photograph anything from ground level.He requested permission to rent a plane and take photos from the air. His request was approved, and arrangements were made. He was told to report to a nearby airport, where a plane would be waiting for him.He arrived at the airport and saw a plane warming up near the gate.He jumped in with his bag and shouted, “Let’s go!”The pilot swung the little plane into the wind, and within minutes they were in the air.The photographer said, “Fly over the park and make two or three low passes so I can take some pictures.”“Why?” asked the pilot.“Because I am a photographer,”he responded, “and photographers take photographs.”The pilot was silent for a moment; finally he stammered, “Y ou mean you’re not the flight instructor?”__T__ 1. The photographer was sent to cover the fires at Y ellowstone National Park. __F__ 2. When he arrived there, the photographer did not know what to do because the smoke was so thick.__ T__ 3. The photographer went to a nearby airport to rent a plane to take photos from the air.___F__ 4. The photographer jumped into the plane and flew it over the park.__ T__ 5. The photographer acted like a flight instructor while taking photos over the park.8. Directions: Listen to the following talk and fill in the blanks with the missingwords. The talk is given twice.In trying to explain the existence of the complicated body structures we see in living things around us, a theory of evolution (进化) has been developed.While most scientists accept this theory, many people do not. They feel it goes against what is written in the Bible (圣经).This theory is that all the plants and animals in the world today have developed in a natural way from earlier forms that were simpler. These earlier forms developed from still simpler ancestors (祖先), and so on back through millions of years to the very beginning when life was in its simplest form,merely a tiny mass of jellylike (胶状的) protoplasm (原生质).In trying to prove that evolution did take place, scientists depend on three chief “signs.”One of these is the study of fossil (化石) remains of animals and plants of past ages. Some of these fossils seem to trace the step of evolution at work. Fossil remains of primitive (原始的) men have been found that go back toa time 1,000,000 years ago. Fossils of certain crablike (似蟹的) animals go backnearly 500,000,000 years. These fossils show that fish developed in the waters of the earth before amphibians (两栖动物), amphibians before reptiles (爬行动物), reptiles before birds, and so on. Scientists believe this proves life has progressed from one form to another .9. Directions: Listen to the talk again and then answer the following questions orally.1.Why do complicated body structures exist according toscientists?Because of evolution.2. Why is the theory of evolution acceptable to most scientists?Because it proves that all the plants and animals in the world today have developed in a natural way from earlier forms that were simpler.3. Why do scientists study fossil remains?Because they can prove that evolution did take place.4. What do these fossils show?That fish developed in the waters of the earth before amphibians, amphibians before reptiles, reptiles before birds, and so on.5. What is the theory of evolution?A theory that proves that life has progressed from one form to another.10. Directions: Have a discussion on the topic given below.It is more important to raise questions than to answer them.。
