20．A refrigerator of the future that tells you what to cook with your leftovers and automatically re-orders fresh food is being designed m the UK．The self-cleaning"refrigerator of the future"will automatically place supermarket home delivery orders when required and move food near its use by date to the front of the shelves．
         Researchers hope the fridge could clean itself，cut down on wasted food and offer up recipes，which could be tailored to different countries，cuisines and seasons （调味品）．With the British spending 36 million hours on extra-hour work every year，leaving little time for housework，the refrigerator could help save time during busy modern-day lives．These new developments are oh the way thanks to combined efforts between scientists at the University of Central Lancashire and online supermarket Ocado．
         The planned new qualities include the ability for refrigerators to scan their shelves to see what is in store and use this information to both plan meals and automatically place a supermarket food order．
         The smart fridge will use"nano-articulated（纳米） technology"shelf surfaces，smooth to the touch．The shelf surfaces will have millions of independently controlled micro-tiles （小瓷格） which will move products which soon need to be eaten to the front of the refrigerator．Ultrasound-scanning technology built into the door will allow the refrigerator to"look through"the food on a plate before and after mealtime，meaning it can assess what type and amount of food is wasted．
         Dr Simon Somerville，an expert from the University of Central Lancashire，said．"Cookbooks are lists of food items．For this purpose the most available information that the refrigerator will have is a set of arrangements that allow a set number of ingredients（佐料） to produce a large number of quite different dishes．The key concept in the successful accomplishment of this process is accurate list tracking （跟踪）．"
71．The smart fridge can do the following exceptB．
A．offering up recipes for dishes
B．making the food in it cleaner
C．placing a supermarket food order automatically
D．moving food near its use by date to the front of the shelves
72．The underlined phrase"be tailored to"in Paragraph 2 is similar to"A"．
A．be adapted to     B．be similar to        C．be attached to       D．be unique to
73．"Ultrasound-scanning technology"mentioned in Paragraph 4 is used toA
A．assess the type and amount of the food wasted
B．show the amount of food in store
C．look for food in the refrigerator
D．decorate the refrigerator door
74．According to the last paragraph，we can conclude thatC．
A．the refrigerator can cook different dishes
B．Dr Simon Somerville are strongly against the refrigerator
C．the success of the process lies in the accurate list tracking
D．a well-designed cookbook is included in the refrigerator
75．The passage is probably from aB        
A．book review      B．science report     C．newspaper ad        D．fiction story．

10．All around the world，more and more people are donating their time to take part in online volunteering projects．What motivates them to help strangers without expectation of money or even thanks？
Radha Taralekar helped teach Imelda how to protect herself from HIV，though the two have never met，and neither knows the other's name．From her home Mumbai，the young woman took several weeks to write a guide especially for Imelda-who lost her children to HIV/Aids in Uganda．Taralekar received no payment for the job．Taralekar is one of a number of talented people who regularly donate their time online．But what is driving them to help total strangers，while asking for nothing in return？For Taralekar，the project gave her the chance to use her professional experience．"I want to serve people with my medical knowledge，"she says．
For some，the inspiration to volunteer online was far more personal．After losing his wife to cancer，Tony Selman spent many hours online helping Cancer Research to collect data on the disease．"Seeing how painful she was when my wife was dying，I determined to help scientists find a cure for cancer，"he says．
Interests and hobbies are also one of the factors．In 2011Sam Luk，a designer，joined other online volunteers to try to help the police solve a murder case．Twelve years earlier the body of Ricky McCormick had been found killed in a field in St Louis，Missouri-the only clues being two encoded （被译成密码的） letters found in his pockets．Unable to decipher （破译） the codes，the police posted them online，calling for volunteers to help them make sense of the messages．"I'm interested in patterns and I love Sherlock Holmes，"says Luk．He spent hours every week trying to decrypt the notes，but the case remains unsolved to this day．
For writer Clay Shirky，some large online volunteering projects benefit millions of people，giving him a sense of achievement and generosity．He helps write Wikipedia，the world's biggest encyclopedia （百科全书），which is written entirely by people willing to donate their professional knowledge without any reward．
68．Which of the following is the best title？D
A．What caused Taralekar to help Imelda？
B．What motivates people to help others？
C．Where can we find volunteers online？
D．Why do people help strangers online？
69．We can infer that Radha Taralekar is aA．
A．doctor         B．designer      C．writer    D．policeman
70．Sam Luk volunteered to help the police out ofB．
A．his duty of work                     B．interests and hobbies
C．money rewards                        D．a sense of achievement
71．Which of the following shows the structure of the passage？D
CP：Central Point   P：Point   Sp：Subpoint（次要点）  C：Conclusion
11．The Christmas season is often considered the season of giving．Many of us spend a lot of effort and money in an attempt to give our friends and loved ones the best possible gift．But what is the best gift you could possibly give？
Imagine that your bank gave you an account with $86，400every morning of every day．You could use this amount of money for anything you want．But at the end of every day，the bank tells you that money in the account can only be used within that day．How would you choose to spend this money？
This is the attitude we should take towards the time．Time can never get back．It is the only resource that no one can get more than another person．
Around the holiday season，we find ourselves very busy．It is a point in the year where how you spend your time is crucial．Spending this valuable time to help another human being in need is one of the greatest gifts we can give．We never know when even giving a short amount of time to help or listen to a stranger，could make the rest of their day much more pleasant．
However，the saying that money is time is one of the truest statements ever made．By the act of donating money to a non profit organization which helps-for example，you are allowing that single mother to spend more time looking after her children，instead of being forced to spend time looking for a temporary second job．By donating some money，you have helped someone else use their time for a better cause．
One organization I personally would encourage you to consider spending your time and/or money would be Eva Initiatives，an organization created for the homeless．I have volunteered there twice．It was a very positive experience，and being able to learn more about who lived there really gave me a perspective on the real struggles of the people around us．

33．What is the function of the first paragraph？B
A．To imply choosing the proper gifts for others．
B．To introduce the theme of the passage．
C．To arouse attention from the readers．
D．To show giving gifts is a common practice．
34．What can we conclude from the 2nd and 3rd paragraphs？A
A．Lost time never returns．
B．Time is sure to tell the truth．
C．Time tries friends as fire tries gold．
D．Time can create great wonders．
35．What do you think of the author in the passage？A
A．Warm-hearted．
B．Responsible．
C．Encouraging．
D．Strong-minded．
8．We human beings need to stay in touch with nature-many studies show how much better people feel when in sight to trees．Yet even more importantly，nature itself needs us to stay in touch．Many politicians and scientists have told us that we can"conquer（征服）"nature，but in reality nature will always be beyond our control-we do have the power to destroy it．The fate of all the animals and their habitats depends largely on our attitude towards them．Whether or not we ourselves survive depends on how well we look after the rest．For our sake as well as theirs，we need to consider it seriously．
But how can we give a damn if we spend our lives indoors？Born South London at the end of the Second World War，at least I knew what a sparrow was （they're rare now） and you couldn't put a spade into our tiny garden without cutting a worm in half．We knew，too，that milk comes from cows and that old men can grow amazing carrots on poor land．Ultra-urban （极度城市化）we may have been，but at least we were in touch．
Now we have a generation who frankly are not．So how can they care if the countryside is sold off to the highest bidders，and used to park helicopters，and our crops come courtesy of Monsanto and our livestock lives in factories？They will know no other way．
But if we settle for the ultra-urban life，if we allow all wilderness to be compromised and hand our farming over to industrial chemists then，quite simply，the world will fall apart-as it is doing already．We have to rethink what agriculture is really for，and why，and why conservation matters-to us，as well as to other creatures．Changes of strategy begin with attitude and attitude begins with awareness．

66．Which of the following opinions will the author be for？C
A．Technology will help humans control nature completely．
B．Conquering nature is the pltinote of human socicty．
C．Humans have to find a way to live in harmony with nature．
D．We will lose control of nature with the development of society．
67．The second paragraph is intended to tell us that city people in the pastA．
A．were in close touch with nature
B．managed to survive in the war
C．killed the worms in the earth cruelly
D．had a healthier diet than us
68．The new generation show no concem about the ultra-urban pattern just becauseC．
A．modern agriculture don't need hard work
B．high profits can be made by selling city land
C．they are completely cut off from nature
D．livestock living in factories is cheaper and tastier
69．From the passage we guess that Monsanto is likely to beD．
A．a chemical fertilizer plant
B．a scientist good at farming
C．a construction corporation
D．a big agricultural company
70．Towards the end of the passage，the author reminds us toB．
A．move to the countryside
B．reflect on our past b behaviors
C．leave space for wild animals
D．turn farms into big factories．
15．Just as the world's most respected scientific bodies have confirmed that the world is getting hotter，they have also stated that there is strong evidence that humans are driving the warming．Countless recent reports from the world's leading scientific bodies have said the same thing．For example，a 2010summary of climate science by the Royal Society stated that："There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity．"
The idea that humans could change the planet's climate may be counter-intuitive（与直觉不符的），but the basic science is well understood．Each year，human activity causes billions of tons of greenhouse gases to be released（释放）into the atmosphere．As scientists have known for years，these gases hold heat that would otherwise escape to space，wrapping the planet in an invisible blanket．
Of course，the planet's climate has always been changing thanks to"natural"factors（因素） such as changes in solar or volcanic（火山的）activity，or cycles relating the Earth's going around the sun．According to the scientific literature，however，the warming recorded to date matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere-not the warming we would expect from other possible causes．
Even if scientists did discover another reasonable explanation for the warming observed so far，that would beg a difficult question．As Robert Henson puts it in The Rough Guide to Climate Change："If some newly discovered factor can account for the climate change，then why aren't carbon dioxide（二氧化碳）and the other greenhouse gases producing the warming that basic physics tells us they should be？"
The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two  identical Earths-one with human influence and one without．That obviously isn't possible，and so most scientists are careful not to state human influence as an absolute certainty．

72．In most scientists'opinion，the global warming is mainly caused byD．
A．solar activity
B．volcanic activity
C．the Earth's going around the sun
D．human activity
73．The text is developed byC．
A．giving typical examples
B．following the order of space
C．analyzing a theory and arguing it
D．comparing and finding differences
74．The underline word"identical"meansB．
A．totally different
B．exactly the same
C．extremely important
D．relatively independent
75．Which of the following can be the best title？C
A．Are All the Scientists Really Scientific？
B．Where Is Global Warming Leading Us to？
C．Are Humans Definitely Causing Global Warming？
D．What's Relation of Global Warming and Greenhouse Gases？
5．They may be just passing your office，computer bag slung （悬挂） over one shoulder．Or they may be sitting in a car outside it，causally tapping away at a laptop．They look like innocent passers-by．In fact，they are stealing your corporate secrets．
Drive-by hacking is the trendy term given to the practice of breaking into wireless computer networks from outside the buildings that house them．A recent study in the UK，sponsored by RSA Data Security，found that two-thirds of organizations with wireless networks were risking their data in this way．Security experts patrolled （巡逻） several streets in the City of London seeking evidence of wireless networks in operation．
Of 124 that they identified，83 were sending data without encrypting（加密） them．Such data could readily be picked up by a passer-by armed only with a portable computer，a wireless modem and a few pieces of software that can be freely downloaded from the Internet．
The data could include sensitive company documents containing valuable information．Or they could be e-mail identities and passwords that could be used by hackers to log into corporate networks as if they were legal users．
Most companies using wireless networking technology do not take even the simplest of measures to protect their data．Nearly all wireless network technology comes with some basic security features that need only to be activated （激活） in order to give a minimum level of security，for example，by encrypting the data being passed over the network．
Raymon Kruck，business development manager at Check Point Software，a security technology specialist，believes this could be partly a psychological problem．People see the solid walls of their building as safeguards and forget that wireless networks can extend up to 200 meters beyond physical walls．
Companies without any security at all on their wireless networks make it ridiculously easy for hackers to break in．Switching on the security that comes with the network technology should be automatic．Then there are other basic steps a company can take，says Mr．Kruck，such as changing the passwords on the network from the default （默认） setting．
Companies can also install firewalls，which form a barrier between the internal network and the public Internet．They should also check their computer records regularly to spot any abnormal activity，which might betray the presence of a hacker．
41．According to the study sponsored by RSA Data Security，two thirds of the subjectsC．
A．had most of their company data stolen   
B．depended on wireless computer networks
C．were exposed to drive-by hacking       
D．were unaware of the risk of wireless hacking
42．Whichof the following is NOT considered in the study？A
A．The number of computer hacking incidents．
B．The number of wireless computer networks identified．
C．The way in which data are sent and received．
D．The way in which data are hacked and stolen．
43．Most wireless network technology has．A
A．data encryption program    
B．password security programs
C．illegal-user detection        
D．firewall
44．Raymond Kruck most probably agrees that wireless network security involvesB
A．wireless signal administration  
B．changes in user's awareness
C．users'psychological health     
D．stronger physical walls
45．The passage is lost likely to be seen in aD
A．book review    B．science fiction   C．textbook   D．computer magazine．

以下是这些报道的简要内容介绍，请配对它们的标题．
46．Where did this most popular day for couples come from？And how does it come into beings，year after year？Noel Lenski，professor of the University of Colorado，said the lovers'holiday traces its roots to raucous annual Roman festivals held every year on February 15and remained wildly popular well into the fifth century A．D．C
47．The first Earth Day in 1970was a raucous，radical teach-in that helped spur clean-air，clean-water，and endangered species legislation in the United States．Now，40years later，Earth Day is every day，as the saying goes．The thing is，it's also everyday-environmentalism has become a routine with greenness as much a marketing tactic as a moral pursuit．F
48．Some 242million turkeys were raised in the U．S．in 2010for slaughter，according to the U．S．Department of Agriculture's National Agricultural Statistics Service．Last year's birds were worth about U．S．﹩3.6billion．Before the big dinner，debunk the myths，we need to know that the first"real"U．S．Thanksgiving wasn't until the 1800s and get to the roots of Thanksgiving 2010．D
49．Father's Day traditionally takes a backseat to Mother's Day，and，for the most part，dads are cool with that，experts say．Nevertheless，as traditional roles around the house gradually change，fathers are gaining more attention on their special day，at least as measured in the monetary value of gifts estimated to be given on June 19，2011，when the holiday will be celebrated in dozens of countries．A
50．Cookouts，fireworks，and，of course，a chance to wish Uncle Sam a big"happy birthday"-the day means summer in full swing across the United States and beyond．Besides the founders of the US，Fireworks，first authorized by Congress in 1777，are another legacy．More than 14，000fireworks displays light up U．S．skies each year．E．
9．Expressions about water are almost as common as water itself．
The expression to be in hot water is a very old expression．Hot water was used five hundred years ago to mean being in trouble．One story says it got that meaning from the custom of throwing extremely hot water down on enemies attacking a castle．
That no longer happens．But we still get in hot water．When we are in hot water，we are in trouble．It can be any kind of trouble---serious or not so serious．A person who breaks a law can be in hot water with the police．A young boy can be in hot water with his mother，if he walks in the house with dirty shoes．
Being in deep water is almost the same as being in hot water．When you are in deep water，you are in a difficult position．
To keep your head above water is a colorful expression that means staying out of debt．A company seeks to keep its head above water during economic hard times．A man who loses his job tries to keep his head above water until he finds a new job．
Water over the dam is another expression about a past event．It is something that is finished．It cannot be changed．The expression comes from the idea that water that has flowed over a dam cannot be brought back again．
Another common expression to hold water，is about the strength or weakness of an idea or opinion that you may be arguing about．It probably comes from a way of testing the condition of a container．If it can hold water，it is strong and has no holes in it．If your argument can hold water，it is strong and does not have any holes．
Throwing cold water also is an expression that deals with ideas or suggestions．It means to not like an idea．For example，you want to buy a new car because the old one has some problems．But your wife throws cold water on the idea，because she says a new car costs too much．

59．If Robert says he is in deep water，we may guessB．
A．he is swimming under the water
B．he faces a difficult choice
C．he is tired of changing shoes
D．he nearly breaks a law
60．What can you infer from the passage？C
A．"To be in hot water"can only be used to mention serious trouble．
B．"Water over the dam"is an expression about a future event．
C．Water could be used in the war in the past．
D．All of the expressions using water have unpleasant meanings．
61．If your argument doesn't hold water，then it isB．
A．convincing   B．weak   C．logical  D．disappointing
62．This passage is written mainly to tell usC．
A．the use of water
B．how to use some expressions of water
C．expressions about water and their meanings
