17.Research shows that humans ______ from selfish to unselfish behavior when they are watched.( 。
A.tellB.switchC.rangeD.distinguish

分析 研究表明,在被注視的過(guò)程中,人類從自私轉(zhuǎn)向無(wú)私的行為.

解答 答案B.
考查動(dòng)詞詞義辨析.tell"區(qū)別";switch"改變";range"排序";distinguish"辨別".根據(jù)句意:研究表明,在被注視的過(guò)程中,人類從自私轉(zhuǎn)向無(wú)私的行為.所以答案選B.

點(diǎn)評(píng) 本題考查動(dòng)詞的詞義.動(dòng)詞詞義題一直都是高考考查的一個(gè)熱點(diǎn),它注重考查考生結(jié)合語(yǔ)境準(zhǔn)確選用詞語(yǔ)和正確時(shí)態(tài)語(yǔ)態(tài)的能力和.由于英語(yǔ)詞匯豐富,且用法多變,考生掌握起來(lái)有較大難度,因此在平時(shí)應(yīng)注意詞匯的積累,理解詞語(yǔ)的含義及其常見的習(xí)慣搭配,再聯(lián)系句子所表述的意義和語(yǔ)境,選出正確的答案.

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.

29.As to energy use,the new research from UKERC stresses the importance of
B.
A.zero carbon homes                 
B.the behaviour of building users
C.sustainable building design        
D.the reduction of carbon emissions
30.The underlined word"which"in Paragraph 2refers to"D".
A.the waysB.their homes   C.developments D.existing efforts
31.What are Katy Janda's words mainly about?A
A.The importance of changing building users'habits.
B.The necessity of making a careful building design.
C.The variety of consumption patterns of building users.
D.The role of technology in improving energy efficiency.
32.The information gap in energy useA.
A.can be bridged by feedback facilities
B.a(chǎn)ffects the study on energy monitors
C.brings about problems for smart meters
D.will be caused by building users'old habits.

9.Nikenson's dad died when he was 3,and his mom often couldn't afford his school fees,so he got kicked out of school sometimes.But Nikenson would steal back onto the school grounds and stand outside the open classroom windows to listen,day after day.He studied on his own,keeping pace so that when his mom earned a few dollars,he could enter class again.
Against all difficulties,Nikenson graduated from high school this year,first in his class,with straight A's,and was elected class president.Nikenson is a reminder of the basic saying of life today:gift is universal,but opportunity is not.
Fortunately,with the help of some American people,Nikenson is now receiving a university education.He's benefiting from a program started by Bohan,a young American who was teaching in a Haitian high school.Bohan asked his family and friends to help other Haitians go to college.The program grew and became the Haitian Education and Leadership Program,or HELP,sending hundreds of young men and women to Haitian universities.
"Education works,"Bohan said simply."Good education works for everybody,everywhere.It worked for you,for me,and it works for Haitians.""Over time,I've concluded that education may be the single best way to help people help themselves,whether in America or abroad.Yet,as a nation,we don't put enough money in education.So,in this holiday season,I'd suggest a moment to raise a glass and celebrate those who spread the gift of education."
One clever new high school graduate,Elice,was working as a worker in a village and earning just﹩50a month.HELP sent him to college to study industrial engineering,and he just graduated and found a job at a European company as an engineer for﹩1,500a month.
"The only difference is his access to education,"said Bohan.

21.Why was Nikenson not allowed to enter class sometimes?C
A.Because his father died at an early age.
B.Because he often stole something in the school.
C.Because his family was too poor to afford school fees.
D.Because he liked standing outside the open classroom windows.
22.The underlined sentence in the second paragraph probably meansA.
A.chances are also important to gifted people
B.wise people can succeed in everything they do
C.gift is more necessary than opportunity
D.in life people with gift don't need opportunity
23.What's the purpose of Bohan starting HELP?D
A.To collect money for poor Americans.
B.To build more high schools in Haiti.
C.To send poor American students to study abroad.
D.To help Haitians receive a university education.
24.According to the passage,Bohan thinksB.
A.everyone should work for good education
B.education can make a big difference in life
C.more people will spread the gift of education soon
D.Elice ought to be one of the HELP's members.
