    6．Thanks to this new hands free suitcase，carrying around heavy luggage may soon become a thing of the past．Designed by Israeli company NUA Robotics，this"smart"suitcase can follow you everywhere you go．
    The carry-on suitcase，currently a prototype（雏形），connects to a smartphone app via  bluetooth．It has a built-in camera sensor that can"see"you and follow you around on flat surfaces like airport floors．It comes with an anti-theft alarm to prevent someone carrying it away when you're not looking，and it has a backup battery（备用电池） that you can use to charge（充电） all your devices．
    "It can follow and carry things for people around while communicating with their smartphone，and avoiding obstacles，"explained Alex Libman，founder of NUA Robotics．"We're combining sensor network，computer vision，and robotics．So if you download our app，press the‘follow me'button，the luggage recognizes its user and knows to follow and communicate．"
    NUA is still testing the device and trying improve features like speed and customization（客户定制），but they hope to make the suitcase available to customers in a year's time．If it proves successful，they want to use the Bluetooth pairing technology to automate（使自动化） lots of other devices，like shopping carts at the supermarket．These devices are especially meant to be useful to the physically disabled and elderly．"Any object can be smart and robotic，"Libman told Mashable．"We want to bring robots into everyday life．"
    The Israeli tech company made it clear that the finished product will look just like a regular suitcase．They're planning to partner with a carry-on luggage maker，since the device that makes it"smart"weighs just 2.5pounds and can be fixed on old-fashion luggage．
    With NUA'S smart suitcase，carrying around heavy luggage isn't a burden．But how their invention will handle tough obstacles like stairs？It will be interesting to wait．
    25．According to the passage the"smart"suitcaseC．
    A．can go everywhere it would like to go
    B．is on sale now in the market
    C．can make our hands free during traveling 
    D．was designed by Alex Libman
    26．If you want to use this free hand suitcase，you mustA．
    A．download the app    
    B．avoid obstacles
    C．look at it all the time 
    D．carry a camera
    27．What can we learn about NUA？C
    A．It was a company which was founded by Mashable．
    B．It has improved the features of the device up to now．
    C．It wants to bring more smart and robotic devices into daily life．
    D．It will make the suitcase available to customers in a month．

    16．WASHINGTON   The head of the World Bank says for the first time in human history，it is possible to end poverty around the world．Jim Yong Kim told a Washington audience Tuesday，he wants to make ending world poverty by 2030a top goal for the bank and governments around the world．
    World Bank President Jim YongKim says that the problems of poverty，hunger and inequality are wide，urgent and a matter of survival of millions．
    "We know that despite the great successes of the last decade，there are still about 1.3billion people living in extreme poverty，870million who go hungry every day，and 6.9million children under five dying every year，"he said．
    But Kim told a Washington audience that the previous successful efforts to cut the number of people living in extreme poverty by half give them hope．
    "We are at an auspicious moment in history，when the successes of past decades and an increasingly favourable economic outlook combine to give developing countries a chance--for the first time ever--to end extreme poverty within a generation，"he said in a speech at Georgetown University．"Our duty now must be to ensure that these favourable circumstances are matched with deliberate decisions to realize this historic opportunity．"
    Kim says success will require increasing the speed of economic growth，particularly in South Africa and South Asia．
    But he warned that civil unrest（动乱）could happen if economic growth does not help people at all income levels，and also include women and youth．
    Kim says that the World Bank and other development agencies will have more resources to get this job done right．"Meeting this 2030goal will take extraordinary effort，"he said．
    However，Kim warned that all the progress in fighting poverty could be destroyed by climate disasters unless the nations of the world do more to prevent climate change．

    21．In the opinion of Jim Yong Kim，world povertyD．
    A．is not quite hard to end by 2030            
    B．exists only in Africa and Asia
    C．will be sure to disappear by 2030           
    D．is difficult but hopeful to end by 2030
    22．The underlined word"auspicious"in Paragraph 5most probably means"D"．
    A．unforgettable           B．urgent       
    C．disappearing            D．important
    23．What's the passage mainly about？B
    A．The key of ending world poverty is preventing climate change

    17．In 1943，when I was 4，my parents moved from Coeur d'Alene，Idaho，to Fairbanks，Alaska，where adventure was never very far away．
    We arrived in the summer，just in time to enjoy the midnight sun．All that sunlight was fantastic for Mom's vegetable garden．Working in the garden at midnight tended to throw her timing off，so she didn't care much about my bedtime．
    Dad was a Railway Express agent and Mom was his clerk．That left me in a mess．I usually managed to find some trouble to get into．Once I had a little fire going in the dirt basement of a hotel．I had tried to light a barrel （桶） of paint but couldn't really get a good fire going．The smoke got pretty bad，though，and when I made my exit，a crowd and the police were there to greet me．The policemen took my matches and drove me home．
    Mom and Dad were occupied/busy in the garden and Dad told the police to keep me，and they did!I had a tour of the prison before Mom rescued me.1 hadn't turned 5 yet．
    As I entered kindergarten，the serious cold began to set in．Would it surprise you to know that I soon left part of my tongue on a metal handrail（栏杆） at school？
    As for Leonhard Seppala，famous as a dog sledder （驾雪橇者），I think I knew him well because I was taken for a ride with his white dog team one Sunday．At the time I didn't realize what a superstar he was，but I do remember the ride well．I was wrapped heavily and well sheltered （保护） from the freezing and blowing weather．
    In 1950，we moved back to Coeur d'Alene，but we got one more Alaskan adventure when Leonhard invited us eight years later by paying a visit to Idaho to attend a gathering of former neighbors of Alaska．
    25．What can be inferred about the author's family？D
    A．His father was a cruel man．
    B．His parents didn't love him．
    C．His mother didn't have any jobs．
    D．His parents used to be very busy．
    26．What happened when the author was 4？D
    A．He learned to smoke．
    B．He was locked in a basement．
    C．He was arrested（拘捕） by the police．
    D．He nearly caused a fire accident．
    27．Which of the following is true？A
    A．Leonhard was good at driving dog sleds．
    B．The author spent his whole childhood in Alaska．
    C．Leonhard often visited the author's family after 1950．
    D．The author suffered a lot while taking the dog sled in Alaska．

    B．To look back on his childhood with adventures．
    C．To express how much he misses Leonhard．
    D．To show off his pride in making trouble．

    14．Etymology，the study of words and word roots，may sound like the kind of thing done by boring librarians in small，dusty rooms．Yet etymologists actually have a uniquely interesting job．They are in many ways just like archaeologists （考古学家） digging up the physical history of people and events．The special aspect of etymology is that it digs up history，so to speak，through the words and phrases that are left behind．
    The English language，in particular，is a great field to explore history through words．As a language，English has an extraordinary number of words．This is partly due to its ability to adapt foreign words so readily．For example，"English"words such as kindergarten （from German），croissant （from French），and cheetah （from Hindi） have become part of the language with little or no change from their original sounds and spellings．So English-language etymologists have a vast world of words to explore．
    Another enjoyable thing about etymology for most word experts is solving word mysteries （谜）．No，etymologists do not go around solving murders，like the great detective Sherlock Holmes．What these word experts solve are mysterious origins of some of our most common words．
    One of the biggest questions English language experts have pursued is how English came to have the phrase OK．Though it is one of the most commonly used expressions，its exact beginning is a puzzle even to this day．Even its spelling is not entirely consistent--unless you spell it Okay，it is hard even to call it a word．
    Etymologists have been able to narrow OK's origin down to a likely，although not certain，source （来源）．It became widely used around the time of Martin Van Buren's run for president in 1840．His nickname was Old Kinderhook．What troubles word experts about this explanation is that the phrase appeared in some newspapers before Van Buren became well known．It is likely that Van Buren could be called its primary source．Etymologists will doubtlessly keep searching for the original source．However，it is clear that OK's popularity and reputation have topped those of the American president to whom it has been most clearly linked．
    21．The author mentions the words like"croissant"in Paragraph 2 to showC
    A．words have changed a lot in the two languages
    B．what English-language etymologists are exploring now
    C．English has absorbed many words from other foreign languages
    D．the English vocabulary is difficult to the non-English-speaking people
    22．The underlined word"pursued"in Paragraph 4 meansB．
    A．looked upon     
    B．dug up    
    C．put in        
    D．set down
    23．We can learn from the passage that etymologistsA．
    A．discover the possible origin of words 
    B．help detectives to solve mysterious murders
    C．write interesting stories for some newspapers
    D．explore the English language as well as the recent events
    24．What most probably is the major purpose of the passage？C
    A．To present the history of English words．
    B．To explain what an etymologist does for his job．
    C．To introduce the pleasure of the study of words and word roots．
    D．To teach readers how to tell English words from non-English words•

    1．One morning，my husband Jerry went back to the kitchen as he just finished loading his car．"I guess filling my thermos（保温瓶） is all that I have left to do，and then I'm off．"Down the drain（下水道） went the hot water that had been warming his thermos．
    With a nostalgic（怀旧的） look on his face，he softly said："Anytime I fill my thermos I think of your mom．"The tone in his voice was so tender（温柔的） as he spoke of my mother，who is sadly no longer with us．
    "Oh honey，I know she's watching and listening right now with a big smile on her face，"I responded，tears in my eyes．
    One morning years ago when we were leaving，mother watched as Jerry was to fill his thermos．Mom then casually said，‘Jerry，if you filled your thermos with hot water and let it sit a while，your coffee would stay hot for longer then．"With her simple suggestion，his face showed that he was shocked by his own lack of common sense．Well，of course it would!
    He poured out the small amount of coffee already in the thermos and refilled it with boiling hot water．Then he poured the water and refilled it with hot coffee．Mom smiled as Jerry did so．
    Words of wisdom from a loving mother-in-law made an impact（影响） that will never be forgotten．She never dreamed her words would be a treasured and everlasting memory in the heart of her son-in-law．
    The lasting memories don't necessarily come from major moments in life．Memories are often made during those small，ordinary times．Life is about small moments we share with friends and loved ones．
    1．Which word best describes the author's feeling in Paragraph 3？D
    A．Concerned         
    B．Confused         
    C．Interested         
    D．Touched
    2．The underlined part"don't necessarily"is similar in meaning toB．
    A．out of the question                      
    B．possibly but uncertainly
    C．certainly and absolutely                  
    D．without any doubt
    3．The message that the story intends to convey（传达） isA．
    A．that lasting memories come from small things
    B．how valuable a mother's advice is to her children．
    C．what a wise woman the mother is to her son-in-law
    D．why we should respect our parents and listen to them．

    （36）C．But it never lets you know，because，you keep it busy thinking about your friends or favorite stars．So it silently serves your needs and never lets itself grow．When mind loses its freedom to grow，creativity sets a full stop．This might be the reason why we all sometimes think"What happens next？"，"Why can't I think？"

    This is nothing but creativity．（39）E Within no time you can start talking with your friends in English or any other language and never run out of the right words．
    So guys，do give food for your thoughts by reading，reading and more reading．（40）A．Go and get a book!
    A．Now what are you waiting for？

    1．In many parts of the world，cars play an important role in daily life and many societies would not exist without them．（71）E But this is the prediction made by a team of transport researchers who are taken seriously，not only by government but also by car manufacturers．
        The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program．（72）AThat will mean much saving，no accidents and better use of roads．The super-intelligent car in the future will drive itself．（73）CInstead，we will have a choice of cars and change them as frequently as we change our clothing．
         According to Dr．David Davis，who leads the research team，these predictions are based on the rising cost of the car culture，which had blocked up our cities，polluted our air，and caused more deaths than both world wars put together．
        Davis says．ears will be fitted with some intelligent devices（装置）to regulate（调节）the distance between one car and another．（74）GComputers are much safer drivers than people，so cars in a road train will be able to drive much closer together than cars driven by people． 
        By 2010，Dr．David Davis believes，car technology will give motorists a clear view of the road，whatever the weather conditions，by projecting an image of the road ahead on to the car's windscreen．（75）DCars will be connected by an electronic tow bar to the car in front to form"road-trains"．"The front vehicle in such a train bums the normal amount．"says Davis．"but all the others in the train would bum about ten percent of the normal amount，and so produce about ten percent of the pollution．"

    A．The team there believes that by 2030 all cars will be computerized．
    B．They believe that cars will become more important in 20 years．
    C．And it will not be owned by one individual．
    D．And by 2030，cars will travel in line，linked to each other electronically．
    E．So the idea that in 20 years'time，no one will own cars may be hard to believe．
    F．Every driver will use less fuel in the car he owns．
    G．The car will automatically speed up，or slow down，to match the speed of the car in front．
