为了应对全球变暖，需要节能减排，各行各业都有潜力可挖。在啤酒行业，全球最大的啤酒公司也研究出了生产啤酒时节约能源和水的方法。
A greener way to make beer

Bubbles are said to be crucial in determining the taste of a beer. Traditionally, gas bubbles in the early stages of brewing are generated through the natural cooking process, requiring bountiful（大量的） levels of water and heat.
bubble /ˈbʌb(ə)l/ n. 气泡
crucial /ˈkruːʃ(ə)l/ adj. 至关重要的
determine /dɪˈtɜːmɪn/ v. 决定
traditionally /trəˈdɪʃ(ə)n(ə)li/ adv. 传统上（由traditional加后缀-ly变成副词）
gas /ɡæs/ n. 气体
stage /steɪdʒ/ n. 阶段
brew /bruː/ v. 酿制（啤酒）
generate /ˈdʒenəreɪt/ v. 产生、生成
process /ˈprəʊses/ n. 过程、工艺流程
level /ˈlev(ə)l/ n. 数量
The Belgium-based company AB InBev, which is the world's largest brewer, says it has developed a technique to generate the gas bubbles that remove unwanted aromas from the mix of grain and water, known as the wort, without resorting to the traditional method of boiling it.
Belgium /ˈbeldʒəm/ n. 比利时
-based /beɪst/ 后缀，意思是“以…为总部的”
AB InBev 百威英博（百威啤酒就是该公司旗下的品牌）
brewer /ˈbruːə(r)/ n. 啤酒酿造者、啤酒公司
technique /tekˈniːk/ n. 工艺、技术
unwanted /ʌnˈwɒntɪd/ adj. 不需要的（由want的过去分词加上表示否定的前缀un-）
aroma /əˈrəʊmə/ n. 香味
resort /rɪˈzɔːt/ to （在没有其他办法时）诉诸于
traditional /trəˈdɪʃ(ə)n(ə)l/ adj. 传统的（由tradition加后缀-al变成形容词）
The company conducted four years of tests at an experimental brewery in Leuven, east of Brussels, and then on a larger scale in plants in the UK and elsewhere in Belgium. The method it has developed does not detract from the taste of the finished drink, it says, while using less heat and water.
conduct /kənˈdʌkt/ v. 做、实施
experimental /ɪkˌsperɪˈment(ə)l/ adj. 试验性的（由experiment加后缀-al变成形容词）
brewery /ˈbrʊəri/ n. 啤酒厂
Brussels /ˈbrʌs(ə)lz/ n. 布鲁塞尔（比利时首都）
scale /skeɪl/ n. 规模
plant /plɑːnt/ n. 工厂
elsewhere /elsˈweə(r)/ pron. 其他地方
detract /dɪˈtrækt/ from 减损、使逊色
The new method involves heating the brew to below boiling point and then blowing nitrogen（氮气） or CO2 into the tank to create bubbles without changing the taste. The company claims that because the beer is brewed at a lower temperature in the early phase, it can also stay fresh for longer. The bubbles found in the finished product are still to be produced in the normal way, typically by the yeast's digestion of sugars or by pressurisation（受到压力） in the kegging（装桶） process.
brew /bruː/ n. 啤酒
tank /tæŋk/ n. 水箱、液罐
claim /kleɪm/ v. 声称
phase /feɪz/ n. 阶段
typically /ˈtɪpɪk(ə)li/ adv. 典型地、常常（由typical加后缀-ly变成副词）
yeast /jiːst/ n. 酵母菌
digestion /daɪˈdʒestʃ(ə)n/ n. 消化
David De Schutter, the company's research director for Europe, said: "Boiling and these gas bubbles are the sacred formula in the brewing process. Each brewer goes through a boiling process. Our innovation is to heat everything up to just below boiling point, which provides 80% energy savings at this point in time. There is a lot less steam released, which allows you to spend less on water. In our case, we managed to go from 5% evaporated water to less than 1%."
sacred /ˈseɪkrɪd/ adj. 神圣的、不可违背的
formula /ˈfɔːmjulə/ n. 标准做法、准则
innovation /ˌɪnəˈveɪʃ(ə)n/ n. 创新
steam /stiːm/ n. 水蒸汽
release /rɪˈliːs/ v. 释放
manage /ˈmænɪdʒ/ v. 做成某事
evaporate /ɪˈvæp(ə)reɪt/ v. 蒸发、挥发
AB InBev claims that when it has adopted the technique in all its breweries around the world it will reduce its global CO2 emissions by 5% a year, equivalent to the energy consumption of 120,000 families.
adopt /əˈdɒpt/ v. 采纳、采用
global /ˈɡləʊb(ə)l/ adj. 全球的
emission /ɪˈmɪʃ(ə)n/ n. 排放、排放量
equivalent /ɪˈkwɪv(ə)l(ə)nt/ adj. 相等的
consumption /kənˈsʌmpʃ(ə)n/ n. 消耗量、使用量
Studies suggest there will be 80% less evaporation as a result of a 0.5% reduction in water consumption, said to be "the equivalent of 1,200 Olympic swimming pools".
suggest /səˈdʒest/ v. 表明evaporation /ɪˌvæpəˈreɪʃ(ə)n/ n. 蒸发、气化
as a result of = because of
reduction /rɪˈdʌkʃ(ə)n/ n. 减少、降低
equivalent /ɪˈkwɪv(ə)l(ə)nt/ n. 等价物、等量物
Olympic /əˈlɪmpɪk/ adj. 奥运的
The company, which hopes all its breweries will adopt the technique within 10 years, is offering to share the patented technology free of charge with smaller brewers. A fee would be charged to the company's larger rivals in the market. AB InBev has vowed to invest the money in further research to reduce its ecological footprint.
patent /ˈpeɪt(ə)nt/ v. 获得专利
free of charge 免费
rival /ˈraɪv(ə)l/ n. 竞争对手
vow /vaʊ/ v. 发誓
invest /ɪnˈvest/ v. 投资
ecological /ˌiːkəˈlɒdʒɪk(ə)l/ adj. 生态的
footprint /ˈfʊtprɪnt/ n. 脚印、印记（由foot和print组成；ecological footprint指在生态方面的影响）
