Question

15．Not only fashion and music are making a return-houses built in 1970s have proven to be better at cutting energy waste than those built today．The"tea cosy （茶壺套）"design，created in the mid-1970s and built in the early 1980s for low-income people，could provide a blueprint for meeting the Government aims of producing less CO₂ from homes．
The 200 houses were designed to provide low-energy housing，and depend on an inner concrete （水泥） structure that holds in heat，protected by highly insulated （隔熱的） setting which produces a"tea cosy"effect．The ordinary-looking houses also depend on more windows on south-facing sides，with northerly facing doors protected by porches （門廊）．
A study found the houses are 50 percent more energy efficient than the average home and use a quarter of the average energy for space heating．According to researchers，they use less than two-thirds of the power of homes built to meet 2010 building demands．And they will still be 25 percent more efficient than houses built to even more strict proposed demands for 2013．The design is one of the few that will be able to meet 2016 demands for zero-carbon homes．
They were in the beginning fixed with just one or two gas heaters per home，although most now have central heating，depending on the heat from the sun and high insulation to keep steady temperatures inside the house．To be comfortable，they only need to use heating for three to four months a year，compared with seven months for UK home on average，and can be lived with no heating at all．
With many house builders at present worrying that new homes are going to be much more expensive to build in order to meet the Government's ambitious targets，the"tea cosy"model meets this need perfectly．
19．The underlined word"blueprint"is closest in meaning toB．

A．a(chǎn)nalyzing data

21．According to the passage，"tea cosy"houses are better atA．
A．saving heat for energy efficiency
B．producing solar energy at home
C．designing and building materials
D．saving building materials and energy．

Answer 1

分析 本文描述了20世紀(jì)70年代的茶壺蓋房屋設(shè)計(jì)更能滿足現(xiàn)在高標(biāo)準(zhǔn)嚴(yán)要求的建房，而且通過比較可以看出這些茶壺蓋房屋設(shè)計(jì)更節(jié)能減排和環(huán)保．

解答 19．B 詞義猜測(cè)題 根據(jù)第一段的意思茶壺蓋房屋設(shè)計(jì)能為滿足政府減排的目的提供一個(gè)藍(lán)本，接下來(lái)一段描述茶壺蓋房屋設(shè)計(jì)用于當(dāng)前房屋的設(shè)計(jì)模式，故劃線單詞的意思是模型，故答案為B
20．D 細(xì)節(jié)理解題 根據(jù)第三段通過比較說明按照茶壺蓋模式設(shè)計(jì)的房屋比一般的房屋，2010年建房標(biāo)準(zhǔn)及更嚴(yán)格的2013建房標(biāo)準(zhǔn)的房屋更節(jié)能，故第三段是通過比較展開敘述的，故選D
21．A 推理判斷題 根據(jù)文章第三段的比較和第四段的描述可以看出茶壺蓋房屋設(shè)計(jì)的房子擅長(zhǎng)節(jié)能，故A正確．

點(diǎn)評(píng) 閱讀理解題測(cè)試考生在閱讀基礎(chǔ)上的邏輯推理能力，要求考生根據(jù)文章所述事件的邏輯關(guān)系，對(duì)未說明的趨勢(shì)或結(jié)局作出合理的推斷；或根據(jù)作者所闡述的觀點(diǎn)理論，對(duì)文章未涉及的現(xiàn)象、事例給以解釋．考生首先要仔細(xì)閱讀短文，完整了解信息，準(zhǔn)確把握作者觀點(diǎn)．
