2．Law enforcement agencies across the United States are using cameras to take pictures of automobile license plates．The idea is to build a computerized collection of information detailing the daily travel of millions of Americans．
      Detective Mohammed Tabibi uses a license plate reader，also known as a LPR to look for stolen vehicles．"It has somewhat paid．We have caught some people involved in some serious crimes because of the LPR，"said Tabibi．
      The use of LPRs is growing across the United States．Some are fixed to poles along Roadsides，others are placed in law-enforcement vehicles．Privacy groups are concerned about the growing use of these devices．Jay Stanley is with the American Civil Liberties Union  （ ACLU）．"What they  are  also doing  is  storing everybody's time，place，and  location．And  many police departments are holding that information indefinitely．You know in our society，the government doesn't follow you and invade your privacy and track you unless it has a specific  reason that you are involved in wrongdoing，"said Stanley．
      Kevin Rearden served as Captain of the Arlington county Police，who also headed the county's Homeland Security Department before he retired．He said county policy called for the  LPR information to be kept for six months．"We originally had a two-month period，and the  detectives requested the chief extend it to six months because they found in so many investigations，keeping it for two months wasn't long enough，"said Rearden，"but other law  enforcement agencies that use the information may store it for unlimited periods of time．"
     Supporters of privacy rights say they have no problem with police departments taking pictures of license plates to investigate crimes．But Jay Stanley says they're against storing the  information for long periods of time．
     However，Captain Rearden disagrees，"They  keep saying the word'tracking'．I would be  lucky if I could find you in a few places in Arlington at a particular time．By no stretch of the  imagination would I be able to track you．"

57．The function of a LPR itself is toB

分析 目前在美國一些執(zhí)法機(jī)構(gòu)使用車牌識別器來追蹤罪犯，然而這種儀器能記錄上百萬美國人的日常出行，它的使用引發(fā)了人們對隱私問題的擔(dān)憂和爭議．

解答 56．A．主旨大意題．閱讀全文可知，車牌識別器能記錄上百萬美國人的日常出行，它的使用引發(fā)了人們對隱私問題的擔(dān)憂，是有爭議的，這是文章所傳達(dá)的主要內(nèi)容．故選A．
57．B．細(xì)節(jié)理解題．根據(jù)第一段中的"Law enforcement agencies across the United States are using cameras to take pictures of automobile license plates"可知，車牌識別器的基本功能是拍照．故選B
58．B．細(xì)節(jié)理解題．根據(jù)第三段中Jay Stanley的話可知，他們存有每個(gè)人出行的時(shí)間、地點(diǎn)和位置，而且很多警署無限期地保存這些信息．而在美國，除非行為不當(dāng)，政府是不會監(jiān)視你，侵犯你的隱私或?qū)δ氵M(jìn)行跟蹤的，所以Jay Stanley認(rèn)為使用車牌識別器可能會侵犯個(gè)人隱私．故選B．
59．A．細(xì)節(jié)理解題．根據(jù)第四段中的"We originally had a two-month period，and the detectives requested the chief extend it to six months"可知，最初信息被保存兩個(gè)月，后來延長至六個(gè)月．故選A．
60．A．細(xì)節(jié)理解題．根據(jù)最后一段中Captain Rearden的話可知，刻意在警局服務(wù)器上搜索某人，并不能對其進(jìn)行跟蹤．如果能在某個(gè)特定時(shí)間，在某些地方找到某人的蹤跡，那是因?yàn)檫\(yùn)氣好．所以Captain Rearden認(rèn)為跟蹤幾乎是不可能的．故選A．

點(diǎn)評 本篇文章主要是細(xì)節(jié)理解方面的題型，需要考生通過跳讀迅速找到對應(yīng)的句子進(jìn)行詳細(xì)理解，句子的理解可以結(jié)合上下文意思，通過邏輯推理得到．

13．The revised edition of the Dictionary of Modern Standard Chinese has just been released，with more than 100new terms added to it．The new terms include weixin，or WeChat etc．There are also some older words recently used again and repurposed for contemporary（當(dāng)代的） use，such as tuhao．Commonly used in the 1930s to refer to local persons who are rich but cruel，tuhao today laughs at a new privileged class that has appeared in China：people who are"extremely wealthy but lacking in education or values．"
But why did weixin and tuhao make the cut，while other popular terms were shut out？Not admitted to the new edition were such words as diaosi，shengnü，and baifumei．
Li Xingjian，the chief editor of the dictionary，said about 30language experts worked for more than three years to select the new terms．They took into account three main considerations：whether the term has entered public topic，whether the use of the term has become stable and whether the term meets a minimum level of tastefulness．
"We considered and discussed a huge list，"Mr．Li said．"A term like diaosi is not very tasteful，and it's unlikely to be used for much longer．And shengnü，we thought it wasn't that significant．It's used a lot by young people online，but otherwise people don't really use it．"
"On the other hand，tuhao has always been around．It has a mocking（嘲弄的） meaning，but it's not necessarily negative，"he said．"We think it'll stay around for a while，because in real life there really are these kinds of people and therefore a need to describe them．"
The Dictionary of Modern Standard Chinese，first published in 2004，is appreciated especially by scholars and those interested in contemporary usage．But it is not the first reference dictionary in China．That honor still goes to the New China Character Dictionary and the Contemporary Chinese Dictionary．Every five years，the Dictionary of Modern Standard Chinese is revised，with outdated words dropped to make room for new ones．

66．What does the underlined words phrase"make the cut"in Paragraph 2mean？A
A．Select．
B．Exclude．
C．Replace．
D．Explain．
67．How many aspects were taken into consideration to choose the new terms for the dictionary？B
A.2．
B.3．
C.4．
D.5．
68．Why was shengnü not chosen into the new Dictionary of Modern Standard Chinese？D
A．Because it is never used in their daily life．
B．Because it is not popular on the Internet these days．
C．Because it is neither tasteful nor likely to endure long．
D．Because it is not so important and is mainly used online by young people．
69．Which is NOT True according to the passage？B
A．The Dictionary of Modern Standard Chinese was first published in 2004．
B．The Dictionary of Modern Standard Chinese is the first reference dictionary．
C．The term tuhao will exist for some time．
D．About 30language experts worked for over three years to choose the new terms．
70．What is the main idea of the passage？C
A．Every five years，the Dictionary of Modern Standard Chinese is revised．
B．People think differently about the newly chosen terms．
C．Many new terms were chosen into the Dictionary of Modern Standard Chinese．
D．The language experts think highly of newly chosen terms．

10．Businesses are witnessing a difficult time，which has in turn produced influence on consumers'desire to go green．However，shoppers are still laying stress on environmental concerns．
Two thirds of customers say that environmental considerations inform their purchases to the same degree as they did a year ago，while more than a quarter say that they are now even better aware of the environmental effect on what they buy．
This may help to influence how shops store goods on their shelves．And the companies should still make efforts to become more environmentally friendly．Two out of three people think it is important to buy from environmentally responsible companies，with about one in seven saying that they had even decided to take their custom elsewhere if they felt a company's environmental reputation was not good enough．
Harry Morrison，chief executive of the Carbon Trust，sympathizes："I understand this situation where survival is very important now．But from environmental considerations，the clock is ticking-we don't have much time．In addition，cutting carbon emission （排放） has an immediate effect as costs drop and a medium-term benefit for the brand．"
Larger companies have an extra motivation to look at reducing their carbon footprint，as new rules next year will require businesses to buy carbon allowances to make up for their emissions．Those that have taken early action will have a head start．More than two thirds of consumers are not clear about which companies are environmentally responsible．This suggests that firms that are able to convey clearly their message to the public will be in a pole position to attract shoppers．
The Carbon Trust believes that it can help by informing customers about the good work companies are doing．"When companies are granted the standard，they can use a logo in all their marketing，which makes it clear that they are working towards cutting emissions，"Mr．Morrison said．
（Note：Answer the questions or complete the statements in NO MORE THAN 12WORDS．）

78．According to the passage，what is likely to influence shops on what to sell？Customers'environmental concerns
79．A company may lose its regular customers unlessit is environmentally responsible．
80．According to Harry Morrison，businesses will benefit fromcutting carbon emission．
81．According to the last two paragraphs，companies can gain advantages byinforming customers about what they are doing towards cutting emissions．

14．Since IQ testing began a century ago，women have been as much as five points behind，leading psychologists to suggest genetic differences between the male and the female．
That gap has been narrowing in recent years and this year women have moved ahead．
The finding has been made by James Flynn，a world-famous expert on IQ tests．"In the last 100 years，the IQ scores of both men and women have risen but women's have risen faster，"said Flynn．"This is a result of modernity．The complex modern world is making our brains adapt and raising our IQs．"
One possible explanation is that women's lives have become more demanding as they multitask between raising a family and doing a job．Another might be that women have a slightly higher potential intelligence than men and are only now realizing it．
Flynn also made the great discovery that scores in western countries increased by roughly three points a decade，which means people today get 30 more points than those living 100 years ago and that IQs can be improved．
Flynn conducted new IQ tests in western European countries，America，Canada，New Zealand，Argentina and Estonia，which showed that the gap between men and women had become very small．In New Zealand，Estonia and Argentina，women scored slightly higher than men．
Maybe because of this，many women have exchanged the role with their husband in family life．Helena Jamieson，33，works a full-time job and her husband，Luke，37，is a stay-at-home father．Helena said，"I'm definitely the more intellectual person in the relationship and I'm at work full-time rising up the career ladder while he is raising our daughter．"
She added，"In the past，men would look down on me，thinking that I was a woman and not as smart as them．But today，things have changed．I think women probably always know secretly deep down that they are the more intelligent ones-but as the gentler sex，we were just quiet about it in the past and let men believe that they ruled the world．"
33．In the psychologists'view，what led to women getting lower scores than men in IQ tests？B
A．Family genes
B．Genetic differences．
C．Educational levels
D．Job positions．
34．Helena's words in the last paragraph show thatA．
A．women may have been thinking they are smarter
B．men have the right to continue ruling the world
C．things have changed and men have got less clever
D．women were looked down upon，for they were quiet
35．The main idea of the passage is thatD．
A．wives now serve as breadwinners while husbands raise children
B．people today are much smarter than those living 100 years ago
C．in western countries，women scored higher than men in IQ tests
D．women's IQ has risen faster and has even gone beyond men's．

11．Teachers say the digital age has had a good influence-and a not-so-good influence-on this generation of American teenagers．More than 2，000 teachers took an online survey．Three-quarters of the teachers said the Internet and digital search tools have had a"mostly positive"effect on their students'research habits and skills．But 64 percent said the technologies"do more to distract（使------分心） students than to help them academically．"And 87 percent agreed that these technologies are creating an"easily distracted generation with short attention spans．"
The Pew Internet Project did the survey with the National Writing Project．Judy Buchanan is the vice director of the National Writing Project and a co-author of the report．Ms．Buchanan says digital research tools are helping students learn more and faster．"Teachers really favor these tools because they are ways to make some of the learning exciting and engaging．Young people favor these tools．The goal is to really help them become creators of meaningful content，and not just sort of consumers．"
But one problem the survey found is that many students lack digital literacy．They trust too muck of the information they find on the Internet．Judy says these students haven't developed the skills to determine the quality of online information．"It's something that really has to be taught and paid attention to．Because in a world in which things happen quickly，you do need to step back，reflect and analyze the information you have．"
Another problem is blamed on something that might not seem like a problem at all：being able to quickly find information online．Teachers say the result is a reduction in the desire and ability of their students to work hard to find answers．They say students are overly dependent on search engines and do not make enough use of printed books or research libraries．
Many teachers are also concerned that the Internet makes it easy for students to copy work done by others instead of using their own abilities．
32．The text mainly tells usD．
A．a(chǎn)ll the students use digital tools
B．the Internet is playing a key role
C．teachers encourage using digital tools
D．digital tools bring about benefits and problems
33．Which of the following best shows the structure of the text？A

34．The underlined sentence in the third paragraph probably meansD
A．students do not have the right digital tools
B．students do not always have access to the Internet
C．students haven't the ability to adjust themselves
D．students can't judge online information properly
35．Some students don't tend to work hard becauseA
A．they can get answers on the Internet quickly
B．printed books and libraries around aren't enough
C．the Internet can't make students concentrate
D．they can copy each others'work without being punished．
