2．"Eat local．"It's one way to reduce human effect on the planet．Eating local means to try to buy and consume（消耗） foods that are grown in places close to home．However，most of the food sold at supermarkets is not locally grown or produced．Trucks and planes deliver these foods from hundreds or thousands of miles away．During the transportation，greenhouse gases are produced，causing global warming．So the shorter the distance your foods must travel，the less the harm is done to the environment．
But how do you get local food if you live in a large city，hundreds of miles away from farms？Environmental health scientist Dickson Despommier and his students came up with the idea of a"vertical（垂直的） farm"．
A vertical farm is a glasswalled structure that could be built as tall as a skyscraper（摩天大樓）．Since the garden is built upwards，rather than outwards，it requires much less space than an ordinary farm．The world is quickly running out of room for ordinary farming．Vertical farms could be a key to this situation．Despommier imagines a 30story building with a greenhouse on every floor．The walls of the building would be clear，to allow crops to get as much sunlight as possible．Depending on a city's water resources，Despommier thinks hydroponic（水培） farming is another method for the vertical farm which needs no soil to grow plants．
Despommier says the hydroponic greenhouses would use a system that would use a city's waste water and fill it with nutrition to make the crops grow．If this method works，it would provide food to a city and save millions of tons of water．
The idea of a vertical farm has attracted the attention of government officials around the world．Scott Stringer，a government official from New York City，thinks the city is suitable for the vertical farming．"Obviously we don't have much land left for us，"Stringer said，"But the sky is the limit in Manhattan．"
Despommier admits that there is still a lot of work to do to make vertical farms a reality．"But I think vertical farming is an idea that can work in a big way．"he says．
8．Why are people advised to eat local？C
A．Because it means convenience to people．
B．Because it can help people save a lot of money．
C．Because it is environmentally friendly．
D．Because local food has more nutrition．
9．Which is one of the vertical farm's benefits when compared with ordinary farming？B
A．It produces healthier food．
B．It needs less space of the city．
C．It consumes more energy of the city．
D．It does less harm to the cities．
10．From Stringer'words we can conclude thatD．
A．Manhattan has a great potential（潛力） for development
B．there is a limit for using empty land in Manhattan
C．the height of buildings in Manhattan is limited
D．people can make full use of vertical space of Manhattan
11．What can we infer about the vertical farming in the passage？B
A．It has solved the problem of the food shortage in a big way．
B．In a vertical farm，soil may not be needed to grow plants．
C．It is a 30story building with a greenhouse on every floor．
D．Crops are mainly grown in the rainwater in a vertical farm．

17．Electrical devices（儀器）could soon use power made by human energy．Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking，British scientist Max Donelan and other scientists in Canada and the United States developed the device．
The device connects to a person's knee．As the person walks，the device captures energy each time the person slows down．To do this，the device helps with the slowing down movement of the leg，the movements of the walking person push parts of a small machine that produces electricity．Using the device，an adult walking quickly could produce thirteen watts of electricity in just a minute．Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes．
There are several possible uses for the device．Developers say it could help people who work in areas without electricity to operate small computers．The device could also he used in hospitals to operate heart pacemakers，it could even be used to assist in the movement of robotic arms and legs．
The experimental version of the device weighs about one and a half kilograms，but it is too costly for most people to buy，but the researchers hope to make a lighter，less costly version，An improved version should be ready in one year．
The developers hope the device will one day help developing countries； nearly twenty five prcent of people around the world live without electric power．
A similar product was invented in 2005by Larry Rome of the University of Pennsylvania，He created a bag carried on a person's back that also produces power from walking．The knee device does not produce as much electricity as the bag，but the bag requires the walker to carry a load of twenty to thirty kilograms．
32．The second paragraph mainly talks aboutB
A．who developed the device
B．how the device works
C．several possible uses for the devices
D．how much electricity the device can produce
33．What is the disadvantage of the experimental version of the device？C
A．It is too heavy for the walker to bear
B．It is too complex for people to use
C．It is too expensive for most people to afford              
D．It will slow down one's walking speed
34．Compared with the device designed by Larry Rome，this new deviceA
A．produces power without adding more loads to the walker
B．can produce more power in a much shorter time
C．needs to be equipped with a battery        
D．can help the walker walk faster
35．What would be the best title for the passage？C
A．First device powered by walking will soon be on the market
B．Advanced technology brings in a new way to operate heart pacemakers
C．Device gives new meaning to the idea of power walking
D Human energy will become a main source of electricity．

7．One day when I was 12，my mother gave me an order：I was to walk to the public library，and borrow at least one book for the summer．This was one more weapon for her to defeat my strange problem-inability to read．
In the library，I found my way into the"Children's Room．"I sat down on the floor and pulled a few books off the shelf at random．The cover of a book caught my eye．It presented a picture of a beagle．I had recently had a beagle，the first and only animal companion I ever had as a child．He was my secret sharer，but one morning，he was gone，given away to someone who had the space and the money to care for him．I never forgot my beagle．
There on the book's cover was a beagle which looked like my dog．I ran my fingers over the picture of the dog on the cover．My eyes ran across the title，Amos，the Beagle with a Plan．Unknowingly，I had read the title．Without opening the book，I borrowed it from the library for the summer．
Under the shade of a bush，I started to read about Amos．I read very，very slowly with difficulty．Though pages were turned slowly，I got the main idea of the story about a dog who，like mine，had been separated from his family and who finally found his way back home．That dog was my dog，and I was the little boy in the book．At the end of the story，my mind continued the final scene of reunion，on and on，until my own lost dog and I were，in my mind，running together．
My mother's call returned me to the real world．I suddenly realized something：I had read a book，and I had loved reading that book．Everyone knew I could not read．But I had read it．Books could be incredibly wonderful and I was going to read them．
I never told my mother about my amazing experience that summer，but she saw a slow but remarkable improvement in my classroom performance during the next year．And years later，she was proud that her son had read thousands of books，was awarded a PhD in literature，and authored his own books，articles，poetry and fiction．The power of the words has held．
24．The author's mother told him to borrow a book in order toC．
A．encourage him to do more walking    
B．let him spend a meaningful summer
C．help cure him of his reading problem    
D．make him learn more about weapons
25．The book caught the author's eye becauseB．
A．it contained pretty pictures of animals    
B．it reminded him of his own dog
C．he found its title easy to understand      
D．he liked children's stories very much
26．What can be inferred from the last paragraph？A
A．The author has become a successful writer．
B．The author's mother read the same book．
C．The author's mother rewarded him with books．
D．The author has had happy summers ever since．
27．Which one could be the best title of the passage？A
A．The Charm of a Book
B．Mum's Strict Order
C．Reunion with My Beagle
D．My Passion for Reading．

18．For those who are tired doing the laundry，Samsung has found an answer：a washing machine that can tell you when your laundry is done via a smartphone app．
Strange though it may seem-"my wife already does that"was a common response among attendees viewing the device when it was introduced at the Consumer Electronics Show （CES） this week-Samsung is just one of many appliance makers racing to install （安裝） a large number of internet-connected features in machines in an effort to make them"smart"．
Last year，it was a refrigerator that tweeted．This year，it's Wi-Fi-enabled laundry machines and fridges that can tell you when your groceries are going bad．
The washers and dryers，available starting in the spring，connect to any smartphone through a downloadable application．The phone can then be used as a remote control，so the machines can be turned on and off while their owner is at work or on the bus．
Samsung says it's not just something new-the app connection actually has some practical uses．
"If you started to dry clothes in the morning and forgot to take them out，you can go to your phone and restart your dryer for the time when come home，so your clothes are refreshed and ready to go，"said spokesperson Amy Schmidt．
The company also says that with electricity price varying depending on the time of day，more control over when the machines are used can help save money．
Perhaps，but what they will probably really accomplish is what all good technologies do-enable laziness．Rather than getting up to check on whether the laundry is done，users will instead monitor it on their phones while watching TV．

33．What can be inferred from the common response of the attendees at the CES？C
A．The machine will be a big success．
B．their wives like doing the laundry．
C．The machine is unrelated to their life．
D．This kind of technology is familiar to them．
34．What can we learn about the new laundry machines？B
A．They can tell you when your clothes need washing
B．They can be controlled with a smartphone
C．They are difficult to operate
D．They are sold at a low price
35．What is the main idea of the last paragraph？C
A．The laundry should be frequently checked
B．Lazy people like using such machines
C．Good technologies also cause problems
D．Television may help do the laundry．
