2．American high school students are terrible writers，and one education reform group thinks it  has an answer：robots．Or，more accurately，robot-readers-computers programmed to scan  student essays andspit out a grade．
      Mark Shermis，professor of the College of Education at the University of Akron，is helping  to hold a contest，set up by the William and Flora Hewlett Foundation （ WFHF），that promises  $ IOO，OOO in prize money to programmers who write the best automated grading software．"If  you're a high school teacher and you give a writing task，you're walking home with 150 essays，"Shermis  said．"You're going to need some help．"
      Automated essay grading was first proposed in the 1960s，but computers back then were  not up to the task．In the late 1990s，as technology improved，several textbook and testing  companies jumped into the field．Today，computers are used to grade essays on South Dakota's  student writing assessments and a handful of other exams，including the TOEFL test of English fluency，taken by foreign students．
     The Hewlett contest aims to show that computers can grade as well as English teachers-only much more quickly and without all that depressing red ink．Automated essay scoring is"objective，"Shermis said．"And it can be done immediately．If students finish an essay at l0 pm，they get a result at  10：0l pm．"
     Take，for instance，the  Intelligent  Essay  Assessor，a  web-based  tool  marketed  by  Pearson Education，Inc．Within seconds it can analyze an essay for spelling，grammar，organization，and help students to make revisions．The program scans for key words and analyzes semantic  （語義 的） patterns，and Pearson claims that it can understand the meaning of text much the same as a human reader．

46．The text is written to introduceA．
A．robot-readers B．education reform in America
C．Hewlett contest                         
D．William and Flora Hewlett Foundation
47．What does the underlined phrase"spit out"in Paragraph I probably mean？A

D．Check．
48．From Paragraph 3，we know that in the 1960sD
A．computers were not easy to get
B．a(chǎn)utomated grading software was popular
C．people refused automated essay grading
D．computers couldn't grade essays automatically
49．What does Paragraph 4 focus on？B
A．The prize of Hewlett contest．
B．The advantages of automated essay scoring．
C．The application of automated essay scoring．
D．Teachers'opinions about Hewlett contest．
50．The Intelligent Essay Assessor canC．

分析 文章主要介紹了 robot-readers 這一項發(fā)明，包括它的起源、應(yīng)用和功能等．

解答 46：答案 A 主旨大意題．文章主要介紹了 robot-readers 這一項發(fā)明，包括它的起源、應(yīng)用和功能等，所以A項正確．其他三項均非文章主要內(nèi)容，故正確答案為A．
47：答案 A 推理判斷題題．劃線詞所在句"Or，more accurately，robot-readers-computers programmed to scan student essays and spit out a grade．"句意為"或者更確切地說，robot-readers 是瀏覽學生作文并 _____ 分數(shù)的被程序化的電腦"；由第四段最后一句"If students finish an essay at 10 pm，they get a result at 10：01 pm．"可推知，robot-readers 可以給出分數(shù)，因此"spit out"在此意為"給出"，所以A項正確．B項"組織"，C項"分析"，D項"檢查"，均不符合文意，故正確答案為A．
48：答案 D 細節(jié)理解題．由第三段第一句"Automated essay grading was first proposed in the 1960s，but computers back then were not up to the task．"可知，automated essay grading 在二十世紀六十年代就被提出了，但是那時的電腦還不能勝任這項工作．故正確答案為D．
49：答案 B 主旨大意題．第四段大意為：automated essay scoring 可以和英語老師打分一樣好，比英語老師快很多并且沒有那些令人沮喪的紅色筆跡，automated essay scoring 非�？陀^且迅速．由此可知本段主要講 automated essay scoring 的優(yōu)點，故正確答案為B．
50：答案 C 細節(jié)理解題．由文章最后一句"…it can understand the meaning of text much the same as a human reader．"可知，the Intelligent Essay Assessor 可以和人類一樣讀懂文章意思，故正確答案為C．

點評 閱讀理解題主要考查考生對書面語篇的整體領(lǐng)悟能力和接受及處理具體信息的能力．試題的取材，密切聯(lián)系當前我國和世界經(jīng)濟、科技等方面的變化，有關(guān)數(shù)據(jù)的來源真實可信．因此科普知識類文章是每年的必考題．分析歷年的科普類文章我們不難發(fā)現(xiàn)以下特點：
1、文章邏輯性強，條理清楚，語法結(jié)構(gòu)簡單，用語通俗．
2、文章內(nèi)容注重科技領(lǐng)域的新發(fā)現(xiàn)．內(nèi)容新穎，從而使文章顯得陌生，內(nèi)容抽象復雜．
3、命題方面注意對具體細節(jié)的準確理解和以之為依據(jù)的推理判斷．
4、以人們的日常行為或飲食健康入手，探討利弊，詮釋過程，闡述概念．

10．The security industry exists to provide and ensure safety of the population．Teams of developers are constantly working on new devices to better protect not only the people but also their properties．Regular existing technologies such as GPS trackers are also being improved and used in innovative ways to prevent various criminal activities．
Named after Natalia Estemirova，a human rights activist who was kidnapped from her home and murdered within 24 hours，the Natalia Project is a bracelet （手鐲）handed out by the Civil Rights Defenders in hopes of preventing similar tragedies in the future．After all，a majority of human rights activists are situated in constant danger as they fight for freedom and equality．The chunky bracelet was able to produce satisfactory results．Once triggered（觸發(fā)），the bracelets will issue a real-time GPS location of the victim to the Civil Rights Defenders'headquarters．Nearby contacts will also be alerted so immediate action can be taken to rescue the victim．What's most unique about this bracelet is that it will also send an alert to social media platforms such as Twitter and Facebook to notify the public of the attack being placed on the victim．
These bracelets will first be distributed to a small group as funding is still a problem．The first five bracelets were distributed by the human rights organization on Defender's Day in Stockholm，Sweden，on Apr.5，2013．"We would like all human rights defenders at risk to have this alarm，but it costs a lot both for the alarm itself and to build an organization to respond to the alarms and to train the wearers of the alarm．Building a security program around each individual，matched to the specific needs of that person is a complex process．Needless to say，it takes a lot of time and effort to get an alarm up and running to ensure maximum protection for 365 days a year．"
Though the Civil Rights Defenders is an independent non-governmental expert organization，they do receive the support for their hard work through the Swedish Development Cooperation Agency．The potential for this bracelet to prevent kidnapping of regular children and citizens，if made available to the public，will also be endless．
（Note：Answer the questions or complete the statements in NO MORE THAN TWELVE WORDS）
78．What happened to Natalia Estemirova？She was kidnapped and murdered within 24 hours．
79．The Natalia Project aims to ensurethe security/safety of human rights activists．
80．How does the bracelet enable the Civil Rights Defenders'headquarters to take action？By issuing a real-time GPS location of the victim
81．Besides the alarm itself，the cost of the project also includesbuilding an organization to respond to the alarm and training the wearers．．

17．It is well-known that twins are closer to each other than most brothers and sisters----after all，they probably spend more time with each other．Parents of twins often notice that they develop special ways of communicating：they invent their own words and one can often finish the other's sentence．In exceptional circumstances，this closeness becomes more extreme：they invent a whole language of their own，as in the case of Grace and Virginia Kennedy from Georgia in the USA，who communicated so successfully in their own special language that they did not speak any English at all until after they started school．
However，these special relationships are the result of lives spent almost entirely in each other's company．What happens when twins do not grow up together，when they are separated at birth for some reason？Are they just like any other strangers，or are there still special similarities between them？Professor Tom Bouchard，of the University of Minnesota，set out to find the answer to this question．He traced sixteen pairs of twins，who were adopted by different families when they were babies，and often brought up in very different circumstances．Each twin was then interviewed about every small detail of their life．
The results of this research make a surprising reading．Many of the twins were found to have the same hobbies，many have suffered the same illnesses，and some have even had the same type of accident at the same point in their lives．One pair of middle-aged women arrived for their first meeting in similar dresses，another pair were wearing similar jewellery．The most incredible similarities are to be found in the case of Jim Springer and Jim Lewis from Ohio in the USA．The story of the'Jim Twins'made headline news across USA．Born to an immigrant woman in 1939，and adopted by different families at birth，both babies were named Jim by their new parents．
But what can be the explanation for these remarkable similarities？Is it all pure coincidence，or is the explanation in some way genetic？Research into the lives of twins is forcing some experts to admit that our personalities may be at least partly due to'nature'．On the other hand，analysts are also anxious to emphasise that incredible coincidences do happen all the time，not just in the lives of twins．
73．The case of Grace and Virginia Kennedy （Para.1）is to show thatA．
A．twins communicate with each other in an unusual way
B．twins are more likely to suffer from speaking problems
C．most twins have exceptional abilities to invent a new language
D．twins won't have an effective communication until they go to school
74．The purpose of Tom Bouchard's study is to findC．
A．what will happen if twins spend lives entirely in the same company
B．why the 16 pairs of twins have been adopted by different families
C．whether separated growing up has effect on twins'special similarities
D．when the special similarities come into being during their growing up
75．What does the word"reading"in Paragraph 3 most probably mean？B
A．Book．B．Interpretation．C．Literature．D．Measurement．
76．According to Tom Bouchard's research，the special similarities between twinsD
A．depend on what the twins enjoy and suffer from
B．can not be proved or accepted by all the experts
C．result from the twins'growing up and development
D．a(chǎn)re not closely linked with where the twins are raised
77．What can be learned from the last paragraph？C
A．Incredible coincidences happen to twins all the time．
B．Nature is the only way to explain the similarities between twins．
C．The differences between twins are to some extent the results of genes．
D．Similarities shows the close relationship between two strange persons．

7．Hi guys!I'm Lucy the Ladybird and while I'm very much of a lady，I'm not actually a bird but a glowing red beetle（甲蟲） with decorative black spots．
    I'm a friendly little bug，to be honest，and simply like to be close with my pals as long as they handle me very gently．I don't bite humans but I do sink my teeth into mean beasts like aphids （蚜蟲） which，unlike me，are very harmful to all the plants．I milk the aphids just like people do with cows and I milk them dry of all the sap （汁） they have got from your poor plants．I'm a real gardeners'friend and love helping out around the place by pollinating flowers，tidying up plants'fallen leaves and helping to turn them into nice rich fertilizer to feed everything both above and below the soil，and naturally，being so attractive to look at，we are perfect living garden decorations．
   One thing I can not tolerate is all that poisonous pollution from vehicles，garbage burning and other un-environmentally friendly acts that occur in the cities every single minute of the day and night．Pollution of any kind really chokes me to death，so these days，I only live in clean countryside areas，particularly cool ones where it rains and everything grows fresh and green from spring right through to autumn．In winter，when the weather is too cold for me to bear，then I find a nice place to sleep until the snow has gone and I can come back out to play．
   Oh!I almost forgot to tell you that although I am not a bird I do have wings and can fly for short distances．So if you pick me up and let me run up and down your hands and arms，then please don't frighten me by screaming if I suddenly secede to take off!
21．What threatens Lucy the Ladybird most？C
A．Heavy rains．B．Cold weather．C．Air pollution．D．Aphids．

B．It does harm to all growing plants．
C．It lives on the liquid of plants
D．It can fly a long distance．
