2．The behaviour of a building's users may be at least as important as its design when it comes to energy use，according to new research from the UK Energy Research Centre （UKERC）．The UK promises to reduce its carbon emissions （排放）by 80percent by 2050，part of which will be achieved by all new homes being zero carbon by 2016．But this report shows that sustainable building design on its own-though extremely important-is not enough to achieve such reductions：the behaviour of the people using the building has to change too．
The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency （效率），which instead focus on architectural and technological developments．
"Technology is going to assist but it is not going to do everything，"explains Katy Janda，a UKERC senior researcher，"consumption patterns of building users can defeat the most careful design．"In other words，old habits die hard，even in the best designed eco home．
Another part of the problem is information．Households and bill payers don't have the knowledge they need to change their energy use habits．Without specific information，it's hard to estimate the costs and benefits of making different choices．Feedback （反饋） facilities，like smart meters and energy monitors，could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use； some studies have shown that households can achieve up to 15percent energy savings using smart meters．
Social science research has added a further dimension （方面），suggesting that individuals'behaviour in the home can be personal and cannot be predicted-whether people throw open their windows rather than turn down the thermostat （恒溫器），for example．
Janda argues that education is the key．She calls for a focused programme to teach people about buildings and their own behaviour in them．

分析 本文是一篇科教類閱讀，主要講述了英國承諾，到2050年，英國的二氧化碳的排放減少80%．英國能源研究中心的研究發(fā)現(xiàn)，可持續(xù)發(fā)展建筑物的設(shè)計很重要，而改變其使用者的習(xí)慣也很重要．
解答 29．B．細(xì)節(jié)理解題．根據(jù)文章第一段首句The behaviour of a building's users may be at least as important as its design when it comes to energy use，according to new research from the UK Energy Research Centre （UKERC）．可知根據(jù)英國能源研究中心的研究，建筑物使用者的行為也許至少和它的設(shè)計一樣重要．故B正確．
30．D．詞義推測題．此題考查which引導(dǎo)的非限定性定語從句，which指代的是先行詞existing efforts現(xiàn)有的努力．故D正確．
31．A．細(xì)節(jié)理解題．根據(jù)文章第三段Katy Janda 的話consumption patterns of building users can defeat the most careful design．及In other words，old habits die hard，even in the best-designed eco-home．可知建造使用者改變習(xí)慣的重要性．故A正確．
32．A．細(xì)節(jié)理解題．根據(jù)文章第四段Feedback （反饋） facilities，like smart meters and energy monitors，could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use可知反饋設(shè)備能夠縮短信息差距．故A正確．
點評 本文是一篇科教類閱讀，題目涉及多道細(xì)節(jié)理解題，詞義猜測題．做題時學(xué)生應(yīng)仔細(xì)閱讀原文，把握文章主要內(nèi)容，聯(lián)系文章上下文內(nèi)容并結(jié)合所給選項含義，從中選出正確答案，一定要做到有理有據(jù)，切忌胡亂猜測
