14．Dozens of Chicago teenagers on Monday told a small group of elected officials about their need for summer jobs to save for college，pay for food and，in some cases，avoid homelessness．
This summer，Illinois is facing the loss of 18，000jobs for teenagers．The loss comes as teen unemployment in the state has reached a record-high rate of 27.5percent．
Experts say that the slow recovery and the high unemployment rate have forced older workers to take positions for younger workers．
Jim Zeckhauser，the manager of a Chicago social service agency for troubled teens，said he used to be able to place dozens of teens in jobs before the financial crisis．This year，he has been able to place only about seven of the 34teenagers he guides in summer jobs．"It's a struggle to find firms，"he said．
Brent Weiss，owner of Uncle Dan's，an outdoor-gear retailer with locations in Chicago，Evanston and Highland Park，said he is more selective about the workers that he hires，acknowledging that he is more likely to hire college students than teens，and like many other small business he is doing more with fewer workers．
Chicago-area small business say they are taking a wait-and-see approach to expanding their businesses and hiring more workers．They blame increasing gasoline prices and a lack of consumer confidence．
Nationwide，teens ago 16to 19have seen the biggest drop in employment during the past decade．In 2010，the employment rate for that age group was 26percent，the lowest since World war II，according to a report by the Center for Labor Market Studies at Northeastern University In 2000，employment rate for the same group was 45percent．
If the trend continues，only one in four teenagers will hold a job this summer，according to the report．Many of the unemployed will likely be black males living in low-income communities．

29．According to the passage，why do some Chicago teenagers want to take a job？D
A．To know more about the society．

C．To buy some new clothes．
D．To support their education．

Who could have imagined that a treadmill（跑步机）on wheels would one day become a thing？!？Lopifit is an unusual means of transportation that allows you to power an electric bicycle by walking on a treadmill．
Lopifit founder Bruin Bergmeester says it all started when he asked himself the question"How can I use a treadmill outdoors？"He finally came up with a new design，adding an electric motor，and the Lopifit was born．It's similar to an electric bicycle in that the motor only works when the rider puts power in as well．The Lopifit senses when you walk on the treadmill and uses the motor to turn a drive chain at the back of the treadmill，helping you reach a top speed of 17miles per hour．
To use the Lopifit，simply turn on the battery（电池）and use your foot to slide the treadmill backwards and start the motor．Then get on and enjoy the ride!If you need speed，just walk on the treadmill，and if you want to coast（惯性滑行），all you have to do is stay still and admire the view．To stop，you have two hand breaks．
The Lopifit first hit the streets in 2014and，unsurprisingly，became a hit overnight．That was actually quite challenging for the company，because it started getting calls for orders，but it was nowhere near ready for mass production．The unique treadmill bicycle could be bought this year，and Lopifit is struggling to keep up with demand，although the price is up to $2，115．
Some people consider this means of transportation stupid and unnecessary，although there is a very loyal fan-base of so-called Lopifitters．They simply believe that if you're going to walk，you might as well do it the old-fashioned way．
But the Lopifit does have the special advantage of helping you"walk"really fast without much effort，or walking at cycling speed，if you will．

24．Lopifit is an electric bicycle whichC．
A．can be powered by the drive chain
B．can work without an electric motor
C．works when you walk on the treadmill
D．stops when you slide the treadmill forward
25．What is Paragraph 3 mainly about？D
A．The design of a Lopifit．
B．The function of a Lopifit．
C．The structure of a Lopifit．
D．The operation of a Lopifit．
26．What is probably the author's attitude towards Lopifit？A
A．Confident．B．Concerned．C．Curious．D．Doubtful．

11．When you need to see a doctor，surely you will want to see a good one．But there is one important thing you may never have thought about：Has your doctor rested enough？
Doctors in our country often have to work 34 hours or longer without sleep．Most of them work 104hours a week，and some even 150．（There are only 168 hours a week!）One report said that a doctor who works such long hours cannot think more clearly than a drunk driver．Another found that doctors who sleep 5.8fewer hours than the week before might make 22% more serious mistakes．Surely no one wants to get in a car that is driven by a drunk driver．So，how safe would you feel when you are under the care of a tired doctor？
Sadly this problem has been around for a long time．There are no laws about it yet and hospital bosses don't look like they care either．And that is why we doctors are asking you to join us on the street this Sunday．Fight together with us on the street so we can fight better for your life in the hospital．

27．What is the purpose of the text？B

4．During the weekend I traveled by the air for the first time in my life．I usual travel by train or bus．It's both cheaper and safe．But to fly in the sky was something new to me．At the end I felt a little nervous．But very soon I became exciting when I found me high up in the sky among the clouds．I also found that mountains，fields，river and so on were interestingly small．I enjoy the frightening and comfortable journey very much．After all，it is more interesting take a plane than to take a car．

5．Concussions（脑震荡） are brain injuries that occur when a person receives a blow to the head，face，or neck．Although most people may feel dizzy，sick and sleepy at first，these symptoms often disappear after a few days．The long-term effects of concussions，however，are less understood and far more severe．Recent studies suggest that people who suffer multiple concussions are at a significant risk for developing chronic traumatic encephalopathy （CTE），a brain disorder that causes a variety of dangerous mental and emotional problems to arise weeks，months，or even years after the initial injury．These psychological problems can include depression，anxiety，memory loss，inability to concentrate，and physical aggression．The majority of people who develop these problems are athletes who participate in popular high-impact sports，especially football．Although both new sports regulations and improvements in helmet technology can help protect players，the media and fans alike bear some of the responsibility for reducing the incidence of these destructive injuries．
Improvements in diagnostic technology have provided a lot of evidence to link severe-and often fatal-psychological disorders to the head injuries players receive on the field．In response to the growing understanding of this danger，the National Football League （NFL） has revised its safety regulations．Players who have suffered a head injury on the field must give a"concussion sideline assessment"-a series of mental and physical fitness tests-before being allowed back to the game．In an effort to reduce the amount of head and neck injuries on the field，NFL officials have begun enforcing stricter penalty calls for helmet-to-helmet contact，leading with the head，and hitting a defenseless player．Furthermore，as of 2010，if a player's helmet is accidentally pulled off his head during a game，the ball is immediately whistled dead．There is hope that these new regulations，coupled with advances in helmet design，will reduce the number of concussions players suffer，thus controlling the number of CTE cases．
Efforts by the NFL and other professional sports leagues are certainly praiseworthy； indeed，we should commend every attempt to protect the mental and physical health of players．However，new regulations at the professional level cannot protect amateur players，especially young people．With appropriate equipment and form，tackling （擒抱） need not be dangerous．Proper tackling form-using the arms and shoulders to aim for a player's midsection（中间部分） rather than leading with the top of the head-should be taught at an early age．Youth，high school，and college leagues should also adopt safety rules even stricter than the NFL's．Furthermore，at an early age，athletes should be educated about the serious dangers of head injuries．
Perhaps the most important factor in reducing the number of brain injuries，however，lies not with the players，the coaches，or the administrators，but with the media and fans．Sports media producers have been used to showing the most aggressive tackles and the most intense plays．NFL broadcasts often replay especially violent collisions，while the commentators admire the physical ability of the players involved．Some sports programs even feature the countdowns of the hardest hit．When the media focuses on such dangerous behavior，professionals are rewarded for injuring each other on the field，and amateurs become more likely to try to imitate their favorite NFL athlete．Announcers，commentator，television producers，and sportswriters should engage in a collective effort to stop glorifying violent plays．In turn，fans should stop expecting their favorite players to put their lives online for the purposes of entertainment．Players must stop being encouraged to trade their careers，health，happiness，and their lives for the sake of a game．

63．According to the passage，the author believes thatB．
A．NFL officials have not completely carried out safety regulations
B．sports fans and the media share some of the blame for athletes'injuries
C．parents should warn their young children about the danger of playing football

A．There is a close link between CTE and head injuries．
B．NFL officials have done a lot to address the problem of CTE．
C．Safety regulations should be strictly observed by football players．
D．Concussion sidelines assessments play an important role in protecting players．

A．inexpert
B．aggressive
C．enthusiastic
D．strong
66．The author's tone in the passage can best be described asC．
