2．Global Positioning Systems（全球定位系統(tǒng)） are now a part of everyday driving in many countries．These satellite-based systems provide turn-by-turn directions to help people get to where they want to go．However，they can also cause a lot of problems，send you to the wrong place or leave you completely lost．Many times，the driver is to blame．Sometimes a GPS error is responsible．Most often，says Barry Brown，it is a combination of the two．
Barry Brown is with the Mobile Life Centre in Stockholm，Sweden．He told us about an incident involving a friend who had flown to an airport in the eastern United States．There he borrowed a GPS-equipped car to use during his stay．Mr．Brown says，"They just plugged in an address and then set off to their destination．And，then it wasn't until they were driving for thirty minutes that they realized they actually put in a destination back on the West Coast where they lived．They actually put their home address in．So again，the GPS is kind of'garbage in garbage out'．"
Mr．Brown says this is a common human error，but what makes the problem worse has to do with some of the shortcomings，or failures，of GPS equipment．He says，"One problem with a lot of the GPS units is they have a very small screen and they just tell you the next turn．Because they just give you the next turn，sometimes that means that it is not really giving you the overview that you would need to know that it's going to the wrong place．"
Mr．Brown says，"One of the things that struck us，perhaps the most important thing was that you have to know what you're doing when you use a GPS．There are these new skills that people have developed．There are these new competencies（資格） that you need to have to be able to use a GPS because they sometimes go wrong．This goes against a common belief that GPS systems are for passive drivers who lack navigational skills．"
Barry Brown says to make GPS systems better we need a better understanding of how drivers，passengers and GPS systems work together．

41．According to Barry Brow，in most cases，C are blame for the problems．
A．human errors
B．GPS errors
C．errors caused by both drivers and GPS
D．errors caused by putting in a wrong address
42．The example of Barry Brown's friend is used to show thatD．
A．GPS is nothing but garbage
B．GPS is still not accurate enough
C．it is difficult for drivers to use GPS equipment．
D．sometimes drivers are responsible for the problem
43．It can be inferred from the second paragraph thatC．
A．It's impossible to drive from the east to the west in the US．
B．Barry Brown's friend went to Stockholm，Sweden by plane．
C．Given wrong instructions，the GPS will produce wrong results．
D．GPS systems are for passive drivers who lack navigational skills．
44．Which of the followings is one of the shortcomings of GPS equipment？A
A．It tells the driver to turn once at a time．
B．It gives the driver the overview．
C．Its screen is too small to be seen clearly．
D．It is only suitable for passive drivers．
45．What's the main idea of the text？B
A．GPS systems need to be improved．
B．Driving with GPS can be difficult to navigate．
C．Drivers should understand how GPS systems work．
D．Drivers should learn to use GPS systems correctly．

10．I like watching butterflies．Sometimes I think I'm the only girl who notices these quiet but beautiful things．But if it hadn't been for a crowded restaurant，I wouldn't have ever noticed Valeri．
Valeri was a new student．She walked to class with her books against her chest and her head down．She talked only when the teacher asked her a question．After a month at our school，she hadn't made any friend．
One day at lunch，most tables being full，I had nowhere to sit．Valeri sat alone，book in hand．I walked over to her，"Is that a good book？"Valeri gave a small nod and went back to reading．"What's it about？"I asked．After seconds of silence，she looked at me，her eyes shining，"Well，it's about a dragon!This boy，Eragon，finds this dragon egg when he goes playing one day．He thinks it's a rock!The egg hatches（孵化）and Eragon hides the dragon from his cousin and uncle until it gets too big．"
Two weeks later，I was sitting in the auditorium（禮堂）enjoying the talent show．Then a shy girl walked on stage．I recognized her immediately．Valeri held a violin in one hand and a bow in the other．She started to play．The notes formed a soft，sweet tune．The auditorium fell completely silent until we realized the music was finished．I smiled to myself．Valeri wasn't just"a quiet girl"．She knew about wonderful books and could play the violin like nothing I'd ever heard．Like a butterfly，she was beautiful and amazing when you looked closely．

21．The author went to sit beside Valeri becauseC．
A．Valeri invited her to sit there       B．Valeri's book drew her attention

A．Eragon'father   B．Eragon
C．Eragon's cousin D．Eragon's uncle
23．Butterflies are mentioned in the text to showC．
A．the beauty of butterflies  B．the author's interest
C．the character of Valeri    D．the qualities of friends

7．The day when the jobs were handed out was one of the most exciting moments for all the children in the class．It took place during the first week of the term．Every kid was given a job for which they would be responsible for the rest of that school year．
Some jobs were more interesting than others，and the children were eager to be given one of the best ones．When giving them out，the teacher took into account which pupils had been most responsible during the previous year．During the previous year Rita had carried out the teacher's instructions perfectly．All the children knew Rita would be given the best job．
But there was a big surprise．Each child received a normal job．But Rita's job was very different．She was given a little box containing some sand and one ant．Though the teacher insisted that this ant was very special，Rita felt disappointed．Most of her classmates felt sorry for her．Even her father became very angry with the teacher and he encouraged Rita to pay no attention to this insignificant pet．However，Rita preferred to show the teacher her error by doing something special with that job of little interest．
Rita started investigating all about her little ant and gave the ant the best food，and it grew quite a bit bigger．
One day，a man，who looked very important，came into their classroom and declared，"Your class has been chosen to accompany me，this summer，on a journey to the tropical rain forest，where we will investigate all kinds of insects．Among all the schools of this region，your class has best cared for the little ant．"
That day the school was filled with joy and celebration．Everyone thanked Rita for having been so patient and responsible．And many children learnt that to be given the most important task you have to know how to be responsible even in what are the smallest tasks．

26．What did the teacher base his decision on when giving out jobs to the children？C
A．Their characters and interests．
B．Their class performance during the previous year．
C．Their working performance during the previous year．
D．Their ability of managing their accounts during the previous year．
27．What does the underlined sentence mean？D
A．Each child got an important job．
B．Each child got an interesting job．
C．The perfect student got the job of everyone's preference．
D．The most responsible student got the job of least interest．
28．What is Rita's attitude to her father's suggestion？A
A．Negative．  B．Uncertain．  C．Totally positive．  D．Acceptive．
29．We can infer that the man who made the declaration is aC．
A．hunter       B．director     C．biologist       D．principal
30．What would be the best title for the passage？B

14．Well，parents，surprise!Lots of us are using Twitter and Facebook to thumb rides，and not just to school．It's awkward to be refused when you call a friend and ask for a ride．But with Twitter，you just look for other people heading the same way．
    It may sound risky，so many teens stay within their own social circles to find rides，and don't branch out beyond friends when asking on Twitter just like me，but to some young people，especially those taking longer trips，stranger danger is less of a concern．
"I think the digital connection of young people is really key，because younger generations grew up sharing things on line，sharing files，photos，music，etc，so they've been very used to sharing，"said Juliet Schor，a sociology professor at Boston College．
    The sharing economy got big during the recession （經(jīng)濟(jì)衰退），allowing people to access more goods，services using technology and even to share costs．And that technology，for me，is what the car was for my mom，a gateway to more freedom，like what my friend Earl says，"The symbol of freedom isn't the car any more because there's technology out there connecting you to a car．"
According to the researchers at the University of Michigan，30 years ago，eight in ten American 18-year-olds had a driver's license compared to six in ten today．So it's not that surprising that on my 16th birthday I wasn't rushing to get a license but an iPhone．
"Driving，for young people，does mean they have to disconnect from their technology，and that's a negative．So if they could sit in the passage side and still be connected，that's going to be a plus．"Schor continued．
To me，another plus is that ridesharing represents something，something much bigger than trying to save money．I see it as evidence that people still depend on each other．My generation shares their cars and apartments the way neighbors used to share cups of sugar．For the system to work，some of us still need our own cars．But until I get my own version of the silver Super Beetle，you can find me on Twitter．

29．The American teens like me，prefer to possess an iPhone as a birthday gift becauseC．
A．it is most fashionable and cool              
B．they are bored with driving cars
C．they are fond of being connected             
D．it is much cheaper than a car
30．We can learn from the text thatB．
A．Twitter is a website for teens to make friends and achieve goals
B．ridesharing can be seen as a sign that people still count on each other
C．driving cars for teens means a plus and connecting with technology
D．having a car and cost-sharing symbolize more freedom for the author's mother
31．Professor Juliet would agree thatD．
A．young people will sit waiting to be contacted by reading a passage
B．sharing economy is bound to be responsible for the recession
C．young people tend to share a car with strangers by means of Twitter
D．being connected via technology comes first for young people
32．The best title for the passage is probablyC
A．Twitter，an Awesome Website             
B．Cars or iPhone
C．Teens Use Twitter to Thumb Rides        
D．Cool Teens on the Go．

12．Wrting artieles about films for The Front Page was my first proper job．Before then I had done bits of reviewing---novels for other newspapers，films for a magazine and anything I was asked to do for the radio．That was how I met Tom Seaton，the first arts editor of The Front Page，who had also written for television．He hired me，but Tom was not primarily a journalist，or he would certainly have been more careful in choosing his staff．
         At first，his idea was that a team of critics should take care of the art forms that didn't require specialized knowledge：books，TV，theatre，film and radio．There would be a weekly lunch at which we would make our choices from the artistic material that Tom had decided we should cover，though there would also be guests to make the atmosphere sociable．
         It all felt like a bit of dream at that time：a new newspaper and I was one of the team．It seemed so unlikely that a paper could be introduced into a crowded market．It seemed just as likely that a millionaire wanted to help me personally，and was pretending to employ me．Such was my lack of self-confidence．
         Tom's original scheme for a team of critics for the arts never took off．It was a good idea，but we didn't get together as planned and so everything was done by phone．It turned out，too，that the general public out there preferred to associate a reviewer with a single subject area，and so I chose film．Without Tom's initial push，though，we would hardly have come up with the present arrangement，by which I write an extended weekly piece，usually on one film．
         The space I am given allows me to broaden my argument---or forces me，in an uninteresting week，to make something out of nothing．But what is my role in the public arena？I assume that people choose what films to go to on the basis of the stars，the publicity or the director．So if a film review isn't really a consumer guide，what is it？I certainly don't feel I have a responsibility to be‘right'about a movie．Nor do I think there should be a certain number of‘great'and‘bad'films each year．All I have to do is put forward an argument．I'm not a judge，and nor would I want to be．
67．What do we learn about Tom Seaton from the first paragraph？B
A．He encouraged Mark to become a writer．
B．He had worked in various areas of the media．
C．He met Mark when working for television．
D．He prefers to employ people that he knows．
68．The weekly lunches were planned in order toC．
A．help the writers get to know each other
B．provide an informal information session
C．distribute the work that had to be done
D．entertain important visitors from the arts
69．What does the author mean when he says that Tom's plan‘never took off'in Paragraph 4？D
A．It was unpopular．
B．It wasted too much time．
C．It wasn't planned properly．
D．It wasn't put into practice．
70．Which of the following best describes what Mark says about his work？C
A．His success varies from year to year．
B．He prefers to write about films he likes．
C．He can freely express his opinion．
D．He writes according to accepted rules．
