3.Waste to Energy-JUST BURN IT!WHY BURN WASTE?
Waste-to-energy plants generate (产生) enough electricity to supply 2.4million households in the US.But,providing electricity is not the major advantage of waste-to-energy plants.In fact,it costs more to generate electricity at a waste-to-energy plant than it does at a coal,nuclear,or hydropower plant.
The major advantage of burning waste is that it considerably reduces the amount of trash going to landfills.The average American produces more than 1,600pounds of waste a year.If all this waste were landfilled,it would take more than two cubic yards of landfill space.That's the volume of a box three feet long,three feet wide,and six feet high.If that waste were burned,the ashes would fit into a box three feet long,three feet wide,but only nine inches high!
Some communities in the Northeast may be running out of land for new landfills.And,since most people don't want landfills in their backyards,it has become more difficult to obtain permits to build new landfills.Taking the country as a whole,the United States has plenty of open space,of course,but it is expensive to transport garbage a long distance to put it into a landfill.
TO BURN OR NOT TO BURN?
Some people are concerned that burning garbage may harm the environment.Like coal plants,waste-to-energy plants produce air pollution when the fuel is burned to produce steam or electricity.Burning garbage releases the chemicals and substances found in the waste.Some chemicals can be a threat to people,the environment,or both,if they are not properly controlled.
Some critics of waste-to-energy plants are afraid that burning waste will hamper (妨碍,阻碍) recycling programs.If everyone sends their trash to a waste-to-energy plant,they say,there will be little motive to recycle.Several states have considered or are considering banning waste-to-energy plants unless recycling programs are in place.Massachusetts,New Jersey,and New York City have delayed new waste-to-energy plants,hoping to increase the level of recycling first.
So,what's the real story?Can recycling and burning waste coexist?At first glance,recycling and waste-to-energy seem to be at odds (不一致),but they can actually complement (弥补) each other.That's because it makes good sense to recycle some materials,and better sense to burn others.
Let's look at aluminum,for example.Aluminum mineral is so expensive to mine that recycling aluminum more than pays for itself.Burning it produces no energy.So clearly,aluminum is valuable to recycle and not useful to burn.
Paper,on the other hand,can either be burned or recycled-it all depends on the price the used paper will bring.
Plastics are another matter.Because plastics are made from petroleum and natural gas,they are excellent sources of energy for waste-to-energy plants.This is especially true since plastics are not as easy to recycle as steel,aluminum,or paper.Plastics almost always have to be hand sorted and making a product from recycled plastics may cost more than making it from new materials.
To burn or not to burn is not really the question.We should use both recycling and waste-to-energy as alternatives to landfilling.
Waste to Energy-JUST BURN IT!
WHY BURN WASTE? | Advantages of waste to Energy | ◆Though at a high (71)cost,waste-to-energy plants can produce enough electricity for 2.4million US households. ◆Burning waste can (72)reduce/prevent/stop a considerable amount of trash going to landfills. |
(73)Difficulties for landfilling | ◆Some communities (74)lack land for new landfills. ◆Most people refuse to build landfills around. ◆Building landfills in far-away areas will increase the cost of (75)transporting garbage. | |
TO BURN OR NOT TO BURN? | (76)Concerns/Worries about burning garbage | ◆Burning garbage releases chemicals,which,if not properly controlled,can be (77)harmful/dangerous to people and the environment. ◆Burning garbage will hamper recycling programs. |
Coexistence of recycling and burning waste | Recycling and waste-to-energy can go well with each other in that some materials like aluminum are fit to recycle,while others like plastics are fit to (78)burn. | |
(79)Conclusion | Whether to burn or not to burn,we should (80)replace landfilling with both recycling and waste-to-energy to deal with garbage. |
分析 本文主要讲述垃圾的合理利用-循环利用和制造能源.
解答 71.cost 72.reduce/prevent/stop 73.Difficulties 74.lack 75.transporting
76.Concerns/Worries 77.harmful/dangerous 78.burn 79.Conclusion 80.replace
71.cost 根据文章第一段In fact,it costs more to generate electricity at a waste-to-energy plant than it does at a coal,nuclear,or hydropower plant.可知发电的成本比较大.
72.reduce/prevent/stop 根据文章第二段The major advantage of burning waste is that it considerably reduces the amount of trash going to landfills. 可知燃烧垃圾可以减少垃圾堆成山.
73.Difficulties 根据文章第三段 Some communities in the Northeast may be running out of land for new landfills.可知一些社区会把土地转变成垃圾填埋场,垃圾填埋场很多困难.
74.lack根据文章第三段,it has become more difficult to obtain permits to build new landfills. 可知获得允许去建造新的垃圾填埋场很困难,也就是说缺少垃圾填埋场.
75.transporting 根据文章第三段it is expensive to transport garbage a long distance to put it into a landfill.可知把垃圾运到距离较远的地方填埋代价较大.
76.Concerns/Worries 根据文章第四段Some people are concerned that burning garbage may harm the environment. 可知一些人关心,燃烧垃圾会影响环境.
77.harmful/dangerous根据文章第四段Some chemicals can be a threat to people,the environment,or both,if they are not properly controlled.可知燃烧垃圾会释放化学物质,对人们和环境都是有害的.
78.burn 根据文章倒数第二段This is especially true since plastics are not as easy to recycle as steel,aluminum,or paper 可知塑料不像钢铁和铝一样可以循环利用,因此只能燃烧.
79.Conclusion 根据文章最后一段We should use both recycling and waste-to-energy as alternatives to landfilling.可知文章最后一段对文章进行了总结.
80.replace根据文章最后一段We should use both recycling and waste-to-energy as alternatives to landfilling.可知我们可以使用循环利用和制造能源去代替掩埋.
