8、 【 C20】 Part A Directions: Read the following texts and answer the questions which accompany them by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1. 20 Officials in Tampa Florida, got a surprise recently when a local firm building the states first ethanol * -production factory put in a r
9、equest for 400, 000 gallons a day of city water. The request by US Envirofuels would make the facility one of the citys top ten water consumers overnight, and the company plans to double its size. Florida is suffering from a prolonged drought. Rivers and lakes are at record lows and residents wonder
10、 where the extra water will come from. They are not alone. A backlash against the federally financed biofuels boom is growing around the country, and “water could be the Achilles heel“ of ethanol, said a report by the Minneapolis-based Institute for Agriculture and Trade Policy. The number of ethano
11、l factories has almost tripled in the past eight years from 50 to about 140. A further 60 or so are under construction. In 2007, President George Bush signed legislation requiring a fivefold increase in biofuels production, to 36 billion gallons by 2022. This is controversial for several reasons. Th
12、ere are doubts about how green ethanol really is(some say the production process uses almost as much energy as it produces). Some argue that using farmland for ethanol pushes up food prices internationally(world wheat prices rose 25% recently, perhaps as a side-effect of Americas ethanol programme).
13、 But one of the least-known but biggest worries is ethanols extravagant use of water. A typical ethanol factory producing 50 m gallons of biofuels a year needs about 500 gallons of water a minute. Most of that goes into the boiling and cooling process, which is similar to making beer. Some water is
14、lost through evaporation in the cooling tower and in waste discharge. All this is putting a heavy burden on aquifers in some corn-growing areas. Residents went to court in Missouri to halt a $ 165 m facility being built by Gulf stream Bioflex Energy LLC which was projected to draw 1. 3 m gallons of
15、water every day from the Ozark aquifer. Projects are being challenged in Minnesota, Iowa, Nebraska, Kansas and in central Illinois, where eight ethanol facilities are situated over the Mahomet aquifer. Demand for corn is such that more land is also being ploughed up in drier regions of the Great Pla
16、ins states to the west of the corn belt, where irrigation is required, increasing water demand further. The good news is that ethanol plants are becoming more efficient. They now use about half as much water per gallon of ethanol as they did a decade ago. New technology might be able to halve the am
17、ount of water again, says Mike Fatigati, vice president of Delta-T Corp, a Virginia company which has designed a system that does not discharge any waste water. But others are sceptical. “There are things you can close loop(i. e. recycle efficiently)and things you cant, “ says Paul Greene, a senior
18、director for biofuels with Siemens Water Technologies, designers of the water-purification technology used in ethanol factories. Perhaps ethanol just isnt as bio-friendly as it looks. * ethanol = alcohol fuel 21 US Envirofuels ( A) is a local company which plans to double its size. ( B) is one of Ta
19、mpas top ten water consumers. ( C) is responsible for Tampas water shortage. ( D) is going to become the largest fuel supplier in Tampa. 22 What does the word “backlash“(line 1, para. 2)mean? ( A) A quick backward movement. ( B) A strong backup action. ( C) A powerful counterattack. ( D) A strong ne
20、gative reaction. 23 What have most people failed to realize about biofuels? ( A) The huge consumption of wheat. ( B) The huge consumption of water. ( C) The amount of waste discharged. ( D) The amount of energy consumed. 24 Which of the following statements is true? ( A) A biofuel factory in Missour
21、i was demanded to reduce its water use. ( B) A big biofuel factory is under construction in Missouri. ( C) The ethanol plants face the challenge of farmland shortage. ( D) The ethanol plants are challenged to move to other regions. 25 What is the authors attitude towards biofuels? ( A) Optimistic. (
22、 B) Neutral. ( C) Encouraging. ( D) Doubtful. 25 In popular discussions of emissions-rights trading systems, it is common to mistake the smokestacks for the trees. For example, the wealthy oil enclave of Abu Dhabi brags that it has planted more than 130 million trees each of which does its duty in a
23、bsorbing carbon dioxide from the atmosphere. However, this artificial forest in the desert also consumes huge quantities of irrigation water produced, or recycled, from expensive desalination plants. The trees may allow its leaders to wear a halo at international meetings, but the rude fact is that
24、they are an energy-intensive beauty strip, like most of so-called green capitalism. And, while were at it, lets just ask: What if the buying and selling of carbon credits and pollution offsets fails to reduce global warming? What exactly will motivate governments and global industries then to join h
