37、appens more than 100 times.While Venice is slowly sinking into the mud on which it stands，Tuvalus rising sea level is caused by global warming.The average global temperature has increased by almost 0.5 centigrade degrees over the past century，scientists expect it to rise by extra 1.3 degrees over th

38、e next 100 years.Warmer weather makes glaciers(冰川) melt，adding more water to the ocean.The warmer temperatures also make water expand，so it takes up more space，causing the sea level to rise.The sea level has risen 10.25cm in the last 100 years.The main cause of global warming is human pollution.Thro

39、ugh burning coal，oil and gas，people have been increasing the greenhouse gases in the atmosphere，such as CO2.This adds to the power of the greenhouse effect，making the planet even warmer.Many scientists believe that，if the warming is not stopped，there will be huge climate changes.The sea level could

40、rise by one meter this century.Should this come true，the sea will swallow up millions of homes and the world will be flooded with “climate refugees” looking for somewhere to live.語篇解讀本文介紹一個因為海平面上升而處在危險中的國家，從而引出全球變暖的問題，并陳述了全球變暖的原因，旨在引起人們的關注。5We can infer from the second paragraph that .ATuvalu is in

41、danger of being swallowed up by the seaBall Tuvalus islands are about five meters above the sea levelCdrinking water in Tuvalu has been destroyedDTuvalu is often flooded by storms and waves答案A解析推理判斷題。根據(jù)第二段的內容可知，在圖瓦盧，海水已經(jīng)進入飲用水供應系統(tǒng)，并且淹沒了一些植物，故選項A(圖瓦盧處在被海水淹沒的危險中)正確。6The author uses Tuvalu and Venice as

42、 examples in order to explain .Athey are the first places sinking into the seaBthey are both sinking into the mud where they standCthey will disappear in the futureDtheir trouble is caused by global warming答案D解析細節(jié)理解題。根據(jù)第三段最后一句可知，文章列舉這兩個例子是為了說明他們的問題都是由全球變暖造成的。故選D。7What does the underlined phrase “cli

43、mate refugees” mean?APeople who are forced away from their homeland by climate.BClimate changes.CRare animals.DClimate effect.答案A解析詞義猜測題。根據(jù)最后一段所表達的意思：如果上述情況成為現(xiàn)實的話，海面會淹沒數(shù)百萬的家，整個世界都是在尋找地方住的“climate refugees”，故“climate refugees”的意思是“由于氣候變化被迫離開家園的人”。故選A。8Which of the following is NOT true according to t

44、he passage?ATuvalus nine little islands are less than five meters above the sea level.BThe average global temperature has risen by 13 centigrade degrees over the past 100 years.CThe warmer temperature causes the sea level to rise.DThere will be huge climate changes unless the warming is stopped.答案B解

45、析細節(jié)理解題。根據(jù)第四段可知，在過去的一百年，全球的平均氣溫幾乎增加了0.5攝氏度，而不是B項中的13攝氏度，故選B。CChicken feathers are useful，and not just to chickens.Some go into pillows，coats and other products.But countless chicken feathers go to waste.In the United States，billions of chickens are produced yearly.Most of their feathers are thrown aw

46、ay.But instead of ending up in landfills(廢物埋填地)，some feathers could find a future in plastics.Scientists in the Washington area have been working with keratin，the main substance(物質) in chicken feathers.One of the products they have developed is a flowerpot which may look like other flowerpots，but th

47、e container breaks down in the earth within one to five years.And as it breaks down，it releases nitrogen(氮) into the soil.The environmentally friendly flowerpot is the work of two researchers Walter Schmidt and Masud Huda.Walter Schmidt has been working to find uses for chicken feathers since the 19

48、90s.Progress in 2002 showed that plastic made from feathers could be formed like other plastics.He says feathers are much stronger and last longer than another plant material，cellulose(纖維素)“Feathers are about eight times as strong as cellulose.By design，feathers are strong and durable(耐用的)” Walter S

49、chmidt also points out that traditional flowerpots can last much longer.But he wonders if there is really a need.He says most flowerpots are never reused.“Why would you want a plastic that you use for a year to last for two hundred years？It makes no sense.You want to match the product with the use，”

50、 he says.Walter Schmidt and Masud Huda are now adding another chicken product to their flowerpotschicken waste.The waste will add more nutrients to the soil as the pot breaks down.The scientists say they hope their flowerpots will be on the market in a year or two.語篇解讀兩位科學家從雞毛里面提取了一種物質，將其制成花盆。這種花盆一到

51、五年內可以分解，釋放出氮。這樣不僅不會破壞環(huán)境，反而對環(huán)境有好處。9What is this passage mainly about?AA new kind of flowerpot will be on the market.BScientists find new uses for chicken feathers.CChicken feathers are not only useful to chickens.DBillions of chickens are produced yearly in the US.答案B解析主旨大意題。通讀全文可知，文章主要是講兩位科學家從雞毛里面提取

52、了一種物質，將其制成花盆，使雞毛有了新的用處。故選B。10From Paragraph 2 we know that .Athe US produces the most chickens around the worldBall chicken feathers will be made into plastics in the futureCchicken feathers will no longer be taken to landfills quite soonDmost chicken feathers are not made use of in the US at presen

53、t答案D解析細節(jié)理解題。根據(jù)第二段中的“Most of their feathers are thrown away.”可知，目前在美國，大部分雞毛都沒有加以利用。11Which of the following is the main feature of the new flowerpot?AIt looks quite different.BIt can be used for years.CIt is environmentally friendly.DIt is made from waste.答案C解析細節(jié)理解題。通讀全文可知，這種新型花盆最大的特征是環(huán)保。第四段中的“The en

54、vironmentally friendly flowerpot”也是提示。故選C。12Walter Schmidt most probably thinks .Apeople should reuse the same flowerpotBit is unnecessary for a flowerpot to last longCnowadays most products dont match their useDpeople prefer to buy flowerpots which last long答案B解析推理判斷題。根據(jù)倒數(shù)第二段中的“Walter Schmidt also

55、points out that traditional flowerpots can last much longer.But he wonders if there is really a need.He says most flowerpots are never reused.”可推斷，Walter Schmidt認為花盆沒必要能用很多年。.七選五To meet the global climate crisis that is approaching，big lifestyle changes are required of those of us.The good news is t

56、hat our way of life can remain meaningful and worthy as our consumption becomes sustainable. 1 Eat less meat and move toward a plantbased diet.This is one of the most effective things we can do because the food we now produce and consume is destroying the very ecosystems that we depend upon for survival.Here are some of the grim facts.The US.uses about onehalf of its land for agricu
