5．See a cellphone cover that you like on Taobao?Forget about placing an order.paying the bill online——青夏教育精英家教网—

5．See a cellphone cover that you like on Taobao？Forget about placing an order，paying the bill online and waiting for days for it to be delivered to you．In the near future，you'll be able to get it in minutes just by hitting"print"on your computer．You might find it hard to believe that you could actually"print"an object like you would a picture．But it is not that hard to understand how it would work．Just as a traditional printer sprays ink onto paper line by line，modern 3D printers spread material onto a surface layer by layer，from the bottom to the top，gradually building up a shape．Instead of ink，the materials the 3D printer uses are mainly plastic，resin and certain metals．The thinner each layer is-from a millimetre to less than the width of a hair-the smoother and finer the object will be．This may sound like a completely new technology，but the truth is that 3D printing has been around since the late 1980s．Back then，it was barely affordable for most people，so few knew about it．Last year，though，saw a big change in the 3D printing industry-printers became much cheaper．For example，10years ago a desktop 3D printer might have cost￡20，000，while now they cost only about￡1，000，according to the BBC．Taken out of the factory and introduced to more diverse and common uses，3D printing can create just about anything you can think of-flutes，bikinis，jewelry，aircraft parts and even human organs．In fact，scientists from Cornell University in New York have just made an artificial ear using a 3D printer，according to Science Daily．The fake ear looks and acts exactly like a natural one．However，as 3D printing becomes more common，it may bring about certain problems-such as piracy．"Once you can download a coffee maker，or print out a new set of kitchen utensils on your personal 3D printer，who will visit a retail store again？"an expert in 3D printing told Forbes News．Even more frightening，what if anyone in the world could use a 3D printer to print out a fully functioning gun？

4．EDGEWOOD-Every morning at Dixie Heights High school，customers pour into a special experiment：the district's first coffee shop run mostly by students with special learning needs．
Well before classes start，students and teachers order Lattes，Cappuccinos and Hot Chocolates．Then，during the first period，teachers call in orders on their room phones，and students make deliveries．By closing time at 9：20a．m．，the shop usually sells 90drinks．"Whoever made the chi tea，Ms．Schatzman says it was good，"Christy McKinley，a second year student，announced recently，after hanging up with the teacher．
The shop is called the Dixie PIT，which stands for Power in Transition．Although some of the students are not disabled，many are，and the PIT helps them prepare for life after high school．They learn not only how to run a coffee shop but also how to deal with their affairs．They keep a timecard and receive paychecks，which they keep in check registers．
Special-education teachers Kim Chevalier and Sue Casey introduced the Dixie PIT from a similar program at Kennesaw Mountain High School in Georgia．Not that it was easy．Chevalier's first problem to overcome was product-related．Should schools be selling coffee？What about sugar content？Kenton County Food Service Director Ginger Gray helped．She made sure all the drinks，which use non-fat milk，fell within nutrition guidelines．

3．Daydreaming was viewed as a waste of time．Or it was considered an unhealthy escape from real life and its duties．Daydreaming has always had a bad reputation，but now scientific research has showed that daydreaming may actually improve your mental health and creativity．It can even help you achieve your desired goals．
Now some people are taking a fresh look at daydreaming．Some think it may be a very healthy thing to do．Researchers are finding daydreaming，they tell us，is a good means of relaxation．But its benefits go beyond this．A number of psychologists have conducted experiments and have reached some surprising conclusions．
Dr．Joan T．Freyberg has concluded that daydreaming contributes to intellectual growth．It also improves concentration，attention span，and the ability to get along with others，she says．In an experiment with school children？the same researcher found that daydreaming led the children to pay more attention to details．They had more happy feelings．They worked together better．Another researcher reported that daydreaming seemed to produce improved self-control and creative abilities．
But that's only part of the story．The most remarkable thing about daydreaming may be its usefulness in shaping our future lives as we want them to be．Industrialist Henry J．Kaiser believed that much of his success was due to the positive use of daydreaming．He maintained that"you can imagine your future．"Florence Nightingale dreamed of becoming a nurse．The young Thomas Edison pictured himself as an inventor．For these famous achievers，it appears that their daydreams came true．
Of course daydreaming is no substitute（代替者）for hard work．You have to work hard to develop skills．Daydreaming alone can't turn you into your heart's desire．But in，combination with the more usual methods of self-development，it might make a critical difference．And who knows：You might see your own daydreams come true．

2．Although most hitchhikers（搭便车的人）are people，passers-by tend to ignore them because they are cautious about giving rides to strangers．But what will they do if they come across a hitchhiking robot？Will they take it to its destination or will they just leave the helpless machine by the wayside？
That is the answer Canadian professors，David Harris Smith and Frauke Zeller，who study  the relationship between humans and technology，are seeking for after they came up with the idea of building a hitchhiking robot．
HitchBOT is built with cheap household items．Thanks to a PC tablet，GPS tracker and camera，hitchBOT not only can send its thoughts and pictures to the general public，but also can answer general questions and keep drivers entertained with small talks．The smart robot is even able to quote（引用）interesting facts about the areas it has passed through．
Not surprisingly，many people are doubtful about hitchBOT's ability．Most people think the cute robot will be damaged by someone．Actually，they are all wrong．The robot hitchhiked all the way from Halifax，Nova Scotia，to Victoria，British Columbia，a distance of 3，700miles．It was first picked up on July 27th by an elderly couple．It not only reached its destination on August 21st，but also had some amazing adventures along the way．It visited national parks，went fishing，went camping，and even attended a wedding where it experienced its first dance and interrupted the bride's speech．
In addition to helping it get to its destination，its Canadian fans have gone out to ensure its safety-from coveting the robot with a plastic cape（披肩）to help keep it dry to ensuring that it stays healthy with motor oil．

24．Why is the hitchhiking robot built？B
A．To help passers-by reach their destinations．
B．To find out how people might react to it．

A．talking with the driver
B．dancing with people
C．sending its thoughts and pictures
D．answering any question raised
26．How long did it take the hitchBOT to reach its destination？A
A．Nearly a month．
B．Over one month．
C．Two months．
D．One week．
27．What can we learn about the hitchBOT？C
A．It was ignored by an elderly couple．
B．It didn't meet with any danger along the way．
C．It experienced a long and amazing journey．
D．It will be put into the market quickly．

1．It was Sunday morning．I heard loud noises of moving furniture in the next room．I could almost feel the excitement of John who was soon going to get a room of his own．I knew how much he longed for his right to privacy when he was sharing a room with his younger brother，Robot．He said，"Mum，Can I have a room of my own？I could use Jeff's．He won't mind．"
It was true that Jeff had graduated from college and flown from the nest．But would he mind？The room was the place where I told him a thousand stories and we had a thousand talks．As close as we were，though，the time came when Jeff needed a door between us．His life was spreading into areas that had less to do with family．I no longer could-or-should know everything about him．
It turned out that getting Jeff's permission was easy．He said，"Of course，Mum，it would be selfish of me to hold on to it．"Then his voice softened，"Mum，I won't be living at home again-you know that．"Behind his glasses，his eyes were lit with all the love．There were no doors closed here-they had all opened up again．
As John and I were cleaning the room，I fixed my eyes on Jeff's things around me and could almost touch the little boy I knew was gone forever．I looked at the room and，in my heart，I let it go．To hold on would be，as Jeff said，selfish．Now it was time for John，shouldering through the door，his eyes bright with promise of independence，to disappear behind the door．It was time for letting go to happen again．

20．Innocent Fast Food Restaurant
A study by academics from the University of California and Northwestern University claimed that"the causal link between the consumption of restaurant foods and obesity （肥胖） is minimal at best．"
It argued that a tax on high-calorie （卡路里） food，（33）whichwas proposed by many health campaigners in the US and Britain，might therefore not be an effective way for governments to deal with the problem．
It analyzed data on calorie intake around the country，which （34）had been collected（collect） before under the leadership of the US Department of Agriculture．The study found that people living closer （35）torestaurants were not significantly more likely to be obese than people living further away，（36）indicating（indicate） that easy access to restaurants had little effect．
It also showed that while restaurant meals typically held more calories than home-produced food，many customers often make up for this by eating （37）less（little） throughout the rest of the day．
"Obese people who ate at restaurants，"the study indicated，"also eat more when they eat at home．"
The US government estimates （38）thatabout one in three Americans，or 100 million in total，are obese．Last month it was predicted that 75 percent of Americans would be overweight in 2020．
The problem is thought to cost Americans between 150billionand170 billion in annual medical costs．
"While taxing restaurant meals might means （39）changing（change） where these consumers eat，"the study's authors，Michael Anderson and David Matsa，wrote，"our study results suggest that a tax （40）wouldbe unlikely to affect their potential tendency to overeat．"

19．When I agreed to stage-managed my school's production of Guys and Dolls，I had no idea of（61）what a stage manager actually did．Still，I （62）decided（decide） that it would be a（n）（63）interesting （interest）experience，and a way to get involved with theater．Besides，if there was already a director and some technicians to build the sets and run lights，how much could there be （64）left（leave）for a stage manager to do？I figured that I would spend a lot of time（65）on rehearsals（彩排）and scripts（剧本）．
I was discouraged by the first rehearsal．I discovered that it was my （66）responsibility（responsible） to make sure that all of the cast actors were present，had scripts，and gave （67）me（I） their schedules before leaving the room．It was not an easy thing．I found that it was impossible （68）to get（get） all twenty-five cast members together for a group scene，since actors kept （69）calling（call）me with emergency appointments，and last-minute family gatherings．
Finally，it was the opening night．I sat to the side of the stage，（70）with my script open on a music stand in front of me．The lights came up，the show began，and I knew that it had all been worthwhile．

18．Home on the Way
People need homes：children assume their parents'place as home； boarders call school"home"on weekdays； married couples work together （33）to build （build） new homes； and travelers …have no place to call"home"，at least for a few nights．
So how （34）about people who have to travel for extended periods of time？Don't they have the right to have a home？Of course they do．
Some regular travelers take their own belongings：like bed sheets，toothbrushes and family photos to make them feel like home （35）no matter where they are； some stay for long periods in the same hotel and as a result become very familiar with service and attendants； others （36）may simply put some flowers by the hotel window to make things more homely．Furthermore，driving a camping car during one's travels and sleeping in the vehicle at night is just like （37）what is generally thought of as"home"--only mobile!
And how about maintaining relationships while in transit？Some keep contact with their friends via internet； some send letters and postcards，or even photos；（38）others may just call and say hi，just to let their friends know that they're still alive and well．People find ways to keep in touch．（39）Making （make） friends on the way helps travelers feel more or less at home．Backpackers in youth hostels may become very good friends，even closer than siblings．
Nowadays，fewer people are working in their local towns，so how do they develop a sense of belonging？Whenever we step out of our local boundaries，there is always another"home"waiting to be found．Wherever we are，with just a little bit of effort and imagination，we can make （40）the place where we stay"home"．

17．One morning，I was waiting at the bus stop，worried about（61）being（be） late for school．
There were many people（62）who/that were waiting at the bus stop，and some of them looked very anxious and （63）disappointed（disappoint）．when the bus finally came，we all hurried on board．I got a place next（64）to the window，so I had a good view of the sidewalk．A boy on a bike（65）caught（catch）my attention．He was riding beside the bus and waving his arms．I heard a passenger behind me shouting to the driver，but he didn't want （66）to stop（stop） until we reached the next stop．Still，the boy kept（67）riding （ride）．He was carrying something over his shoulder and shouting．Finally，when we came to the next stop，the boy ran up the door of the bus．I heard an excited conversation．Then the driver stood up and asked，（68）didanyone lose a suitcase at the last stop？"A woman on the bus shouted，"Oh，dear!It's（69）me/mine（I）"．She pushed her way to the driver and took the suitcase thankfully．Five others on the bus began talking about what the boy had done and the crowd of strangers （70）suddenly（sudden） became friendly to one another．

16．The practice of students endlessly copying letters and sentences from a blackboard is a thing of the past．With the coming of new technologies like computers and smartphones，writing by hand has become something of a nostalgic （怀旧的） skill．However，while today's educators are using more and more technology in their teaching，many believe basic handwriting skills are still necessary for students to be successful-both in school and in life．
Virginia Berninger，professor of educational psychology at the University of Washington，says it's important to continue teaching handwriting and help children acquire the skill of writing by hand．
Berninger and her colleagues conducted a study that looked at the ability of students to complete various writing tasks-both on a computer and by hand．The study，published in 2015，found that when writing with a pen and paper，participants wrote longer essays and more complete sentences and had a faster word production rate．
In a more recent study，Berninger looked at what role spelling plays in a student's writing skills and found that how well children spell is tied to how well they can write．"Spelling makes some of the thinking parts of the brain active，which helps us access our vocabulary，word meaning and concepts．It is allowing our written language to connect with ideas．"Berninger said．
Spelling helps students translate ideas into words in their mind first and then to transcribe （转换）"those words in the mind into written symbols on paper or keyboard and screen，"the study said．Seeing the words in the"mind's eye"helps children not only to turn their ideas into words，says Berninger，but also to spot （发现） spelling mistakes when they write the words down and to correct them over time．
"In our computer age，some people believe that we don't have to teach spelling because we have spell checks，"she said．"But until a child has a functional spelling ability of about a fifth grade level，they won't have the knowledge to choose the correct spelling among the options given by the computer．"
