13．Imagine a town with crosswalks but no pedestrians，cars and trucks but no drivers．Welcome to Mcity，a fake（假的）"city"built by researchers who are testing out the driverless cars of the future．
The controlled test environment，which opened today （July 20，2015）at the University of Michigan in Ann Arbor，covers 32acres （the size of about 24football fields） and contains all the trappings of a real suburb or small city．There is an entire network of roads lined with sidewalks，streetlights，stop signs and traffic signals．There's even a"downtown"area complete with fake buildings and outdoor dining areas．
The idea behind Mcity is simple：test out new driverless car innovations（创新） in a human-free environment before these technologies are unleashed（投放） in the real world．
"Mcity is a safe，controlled，and realistic environment where we are going to figure out how the incredible（难以置信的） potential（可能性） of connected and automated vehicles can be realized quickly，efficiently（有效地） and safely，"Peter Sweatman，director of the Mobility Transformation Center at U-M，said in a statement．
The roads of Mcity are built to stand up to"strict，repeatable"testing，according to MTC officials．While Mcity drivers don't have to compete with real pedestrians，there will be one mechanical foot-traveler （a robot-like machine named Sebastian） that steps out into traffic to see whether the automated cars can hit the brakes in time．The fake city also features a traffic circle，a bridge，a tunnel，some unpaved（未铺砌的） roads，and even a four-lane（四车道的） highway with entrance and exit ramps（坡道），according to a report by Bloomberg Business．
In addition to evaluating fully automated，or driverless cars，the researchers also hope to test out so-called connected vehicles within Mcity's limits．Connected cars can either communicate with one another （vehicle-to-vehicle control，or V2V） or with pieces of equipment，such as traffic lights，that are located near roadways （vehicle-to-infrastructure基础设施 control，or V2I）．
Even the smallest details of Mcity have been planned out in advance to copy the conditions that connected and automated vehicles could face in the real world．For example，there are street signs covered up with graffiti（涂鸦），and faded yellow and white lane markings line the streets．
Mcity is just one part of a much larger project that MTC and its partner organizations are establishing in an effort to get a whole fleet（车队） of connected and driverless cars on the road in Ann Arbor by 2021．In addition to the fake city，MTC is also continuing to launch connected and semi-autonomous（半自动） cars on real roadways．Eventually，the University of Michigan and the Michigan Department of Transportation said they hope to put 20，000connected cars on the roads of southern Michigan．

12．The Link between Fitness and Career Success
It's no mystery to successful people that there is direct link between sound health & fitness and success in their career and personal lives．Successful persons likely show up at the health club consistently，work with a personal trainer，or get up a few minutes early for a heart elevating（增进的） jog．Successful people like to jump start their day with plenty of energy and the feel-good endorphins（内啡肽） that exercise offers．Recent studies prove the direct link between fitness and success．
Better ability to focus，improved confidence and enhanced（增强的） ability to follow through were directly attributed（归属于） to improved fitness levels according to a 2007University of Georgia study．Further，a leading manager search company surveyed more than 1，300managers．When asked to describe their viewpoints of weight and work，75% said good physical fitness is"important for career success at the manager level．"17%，by contrast，said staying in shape is"a nice goal，but secondary（次要的） to good fitness．"
The CEO of that manager search firm said，"Good physical fitness is important to success as a manager in today's work world．''When asked about obesity（肥胖），75% of managers said that being overweight is a"serious career impediment（妨碍）"．Do these responses reflect our obsession with weight loss and mirror the constant reports of skinny（极瘦的） images in popular culture？Probably not．Rather，there is a very strong link between improved fitness and increased productivity，enhanced ability to solve problems，superior energy，not to mention reduced stress and tiredness，all leading to better job performance．It goes well beyond looking good．Fit people tend to have better eating habits and miss fewer days at work due to a higher resistance（抵抗） to illness．And with competition continually increasing in every industry，companies are now rewarding employees and managers who miss less work and produce more．
A study by Jim McKenna，a British researcher，showed that after exercising participants returned to work more tolerant of themselves and more forgiving of their colleagues．The study concluded that"work performance was consistently higher，time management skills improved，as did mental sharpness"．
All it takes is investing 3-4sessions a week，30-45minutes each，to experience these benefits．Combine strength training and cardiovascular（心血管的） exercise，along with sound nutrition to speed up your mental sharpness，enhance your productivity，improve your mood and better manage stress．As your fitness level increases，likely your position on the ladder of success will too!

A．have higher resistance to illness B．get more energy and endorphins
C．lose weight more easily D．care more about their fitness
65．What does the underlined word"obsession"in Paragraph 4mean？A

A．there is no link between fitness and success
B．good physical fitness is critical for career success
C．mental sharpness，productivity and mood can be improved
D．people tend to be more tolerant and forgiving after exercising．

11．Could eating fast food be bad for more than just your health？New research has found proof that eating foods high in sugar and fat could also be bad for your IQ．
Researchers from the United Kingdom and Canada looked at what children ate when compared to their IQ levels．The researcher used surveys to ask parents how often their children ate junk food．The parents were surveyed when the children were aged 3，then followed up 5years later to see how the diet affected the growing children's IQ．They found that those who ate more junk food had lower IQ levels than those who ate a more nutritious diet．
"This suggests that any cognitive（认知的） effects relating to eating habits early in childhood may well continue to exist in later childhood，despite any later changes （including improvements） to dietary intake，"the authors wrote．
The researchers found that dietary habits between the ages of 4and 7did not have as much of an effect as what children ate at age 3did．This may be because the brain grows the quickest during the first three years of life，and thus is more easily affected by things such as diet．
"A possible explanation for this is that the brain grows at its fastest rate during the first three years of life．Studies have shown that head growth during this time is associated with cognitive outcome，and it is possible that good nutrition during this early period may encourage brain growth，"the researchers wrote．
The researchers point out that they have found an association between food and IQ，but not a direct cause or effect．Other factors could have played a role in determining a child's IQ．Parenting，genetics，and even family income are all factors that determine how intelligent a child will be．
Despite this，nutritionists tell us that what children eat can affect how healthy they are，how much rest they get，how smart they are during school．All of these things could change a child's test on IQ level．It is not clear whether food affects IQ directly or indirectly．
More research is needed to determine if there is a direct effect between what a child eats and how intelligent they are．However，the study does suggest that there may be more reasons than just physical health to make sure a child gets a healthy diet．

10．Ulrich's friend Anna was missing at school．His mother said that perhaps she had gone into hiding．That was the hope anyway-that the family had left on their own and had not been sent on one of the prison trains to Germany or Poland．So many people in his city had disappeared since the Nazis came to Amsterdam in 1940．The streets，once crowded with busy shoppers，were now filled with tanks and soldiers．
No one felt safe，except maybe the collaborators（通敌者）．Who were they？Who would betray their friends and let their neighbors be arrested？Ulrich remembered his friend Anna：her father had a small business right down the road from his house．Her sister，Margot，was in the upper school，where Ulrich's sister was in her class．
When he walked to or from school，Ulrich studied the faces of the people on the street．Some looked concerned and cast their eyes downward as they walked，trying not to be noticed．His own parents had that look，like ghosts walking and wondering what had happened to them．The ones that bothered him were those who smiled，who acted like nothing was wrong．"Were they blind？"he wondered．Worse were those who moved into the houses and took the businesses of their missing neighbors．They seemed too assured，too content．They may be Dutch，Ulrich thought，but they are the enemy，too．They were the ones who made the occupation easy．He hoped that when the war was over，the rightful owners would come back and toss them out on their ears．
School was not the same either．It was more than the missing students，though that was the biggest part of it．The teachers，who once seemed to know everything，were different，too．They seemed afraid to teach history，afraid that the authorities would not like what they said．They jumped when a student dropped a book．It was as if they all had to hold their breath．
It was nearly spring．Already tulips（郁金香）were fighting their way out of the cold ground．How many more winters，springs，summers，and falls would go by until they were free？Ulrich waited，and hoped that his friend Anna would soon come home．
