Companies will have to pay increasingly higher prices for the right to emit greenhouse gases. How will this affect the average citizen’s wallet To measure the impact of the 80 per cent target on the UK population, New Scientist approached Cambridge Econometrics, a firm known for its modelling of the European economy. The firm used historic economic data to predict the impact of emissions reductions on prices in over 40 categories of goods and services. It compared the impact of the 80 per cent cut with a baseline situation in which the government takes no action other than the limited emissions restrictions already in place as a result of the (京都议定书). Most of the price increases are a consequence of rising energy costs, in part because coal and gas are re-placed by more expensive low-carbon sources. The price of electricity is projected to be 15 per cent higher in 2050 compared with the baseline. In today’s prices, that would add around ￡5 onto typical monthly household electricity bills. It will also result in higher prices elsewhere, as every industrial sector uses electricity. But electricity and other forms of energy make up only a small part of the price of most goods. Other factors-raw materials, labour and taxes-are far more important. The energy that goes into producing food, alcoholic drinks and tobacco, for example, makes up just 2 per cent of the consumer price. For motor vehicle purchases and hotel stays, the figure is 1 per cent. Only for energy-intensive industries does the contribution climb above 3 per cent. As a result, most products cost just a few per cent more by 2050. At current prices, going low-carbon is forecast to add around 5 pence to the price of a slice of bread or a pint of beer. The price of household appliances such as washing machines rises by a few pounds. There is one major exception to the pattern. Airlines do not currently have a low-carbon alternative to jet fuel. Unless one is found, they will bear the full burden of carbon pricing, and average fares will rise by at least 140 per cent--raising the cost of a typical London to New York return trip from around ￡350 to ￡840. Achieving the overall picture of low prices does require government action. The model forecasts that by 2050 natural gas and petrol will cost 160 per cent and 32 per cent more respectively. To avoid large price rises in home heating and road transport while still hitting the 80 per cent target, the Cambridge researchers had to build two major policies into their analysis. They assumed that future governments will provide grants to help switch all domestic heating and cooking to electricity, and invest in the basic facilities needed for electric cars to almost completely replace petroleum-fuelled vehicles. Both policies have been discussed in recent UK government strategy documents, though the detail of how they would be implemented still needs further discussion. Firm policies must follow if ambitious emissions cuts are going to be made, says Chris Thoung of Cambridge Econometrics. So is tackling climate change going to be easier than expected, in terms of consumer costs While the Cam-bridge Econometrics model is widely respected and regularly used by the UK government’s climate change advisers, any attempt to forecast four decades ahead can be diverted from its intended course by unforeseen events. That leads some economists to question the model’s results. For example, companies could move to countries with less strict carbon regulations, points out Richard Tol of the Economic and Social Research Institute in Dublin, Ireland. Incomes in the UK would fall, making goods relatively more expensive. Tol also questions whether it is reasonable to use historical prices as a basis for projecting beyond 2020. Despite this, the Cambridge Econometrics results, together with other recent studies, do provide a useful guide for governments, says Michael Grubb of the University of Cambridge. They suggest that the overall challenge is conquerable, even if many of the details will only become clear in years to come.According to the modellers, emission cuts won’t change the lifestyle, provided that______. A．the price of food and drink remains stableB．appropriate policies are carried outC．electricity and pettol costs don’t riseD．the public has a strong faith in it

题目解答
答案
B
解析
考查要点：本题主要考查学生对文章主旨的理解，以及根据上下文逻辑关系推断条件句的能力。关键在于识别文章中提到的实现减排目标而不改变生活方式的必要条件。
解题核心思路：
- 定位关键句：题目问及“减排不改变生活方式的条件”，需回到原文中寻找直接关联的条件描述。
- 排除干扰项：需区分“结果”与“条件”，例如文中提到的“食品价格涨幅小”是结果而非条件。
- 锁定政策作用：文章多次强调政府政策（如补贴、投资）对缓解成本上升的作用，这是解题的核心线索。
关键逻辑梳理：
- 文章核心观点：减排会导致能源成本上升，但通过政府政策干预（如补贴、投资），可将商品价格涨幅控制在较低水平，从而避免生活方式改变。
- 政策作用：
- 补贴转向用电：政府提供资金帮助家庭改用电力取暖和烹饪。
- 发展电动车：投资基础设施以推广电动车，减少石油依赖。
- 选项分析：
- B选项直接对应文中“with the right policies in place”（政策到位），是实现目标的必要条件。
- 其他选项或为结果（如A）、矛盾（如C）或未提及（如D）。
