8．Following news of the potential for life on the recently-discovered TRAPPIST-1system，there may be another competitor ready to take its place．
With the help of the Cassini spacecraft，NASA （National Aeronautics and Space Administration） scientists have picked up the first evidence that chemical reactions are taking place deep below the surface of Enceladus，Saturn's （土星的） sixth-largest moon．This means that there could be life in Enceladus'warm underground seas．
An early study found that liquid oceans exist miles below Enceladus'surface．But to reveal what is happening down there，scientists must rely on the plumes（股）of water that spray（喷射）through cracks in Enceladus'icy surface．In October 2015，NASA sent Cassini into a deep dive into one of the plumes．
Cassini's findings，published on April 13in the journal Science，showed that hydrogen（氢） not only exists on Enceladus，but is also responsible for a chemical reaction between hot rocks and water in the ocean beneath its surface．
This same process on Earth provides energy for entire ecosystems around volcanic vents（火山口）．There，tiny creatures are able to survive without sunlight，using hydrogen and carbon dioxide as fuel in a process known as"methanogenesis（甲烷生成）"．
The discovery of this chemical energy source on Enceladus means it could be a very good candidate to host life．
"Confirmation（确认） that the chemical energy for life exists within the ocean of a small moon of Saturn is an important milestone （里程碑） in our search for habitable （可居住的） worlds beyond Earth，"Linda Spilker，Cassini project scientist at NASA，told the Daily Mail．
Alien life was once only thought possible on habitable planets within the"Goldilocks zone"-far enough from our sun not to be a fireball，but not so far as to be freezing．
Research on Enceladus is still in its early stages，but the recent findings have important meanings for future exploration．
"At present，we know of only one genesis （诞生） of life，the one that led to us，"David Rothery，professor of planetary geosciences （行星与地球科学） from the Open University in the UK，told The Telegraph．
"If we knew that life had started independently in two places in our solar system，then we could be pretty confident that life also got started on some of the tens of billions of planets and moons around other stars in our galaxy，"he said．

24．What is the article mainly about？B
A．The connection between the TRAPPIST-1system and Enceladus．
B．The potential for life on Saturn's moon，Enceladus．
C．The chemical energy source on Enceladus．
D．Scientists'constant search for life in the solar system．
25．Scientists assume that there could be life on Enceladus becauseC．
A．there is evidence of a warm ocean under Enceladus'surface
B．hot rocks and water have been discovered on Enceladus
C．hydrogen discovered on Enceladus could be a chemical energy source
D．the entire ecosystems of Enceladus are somewhat similar to those of Earth
26．According to David Rothery，the recent findings on Enceladus could mean thatD．
A．there is only one genesis of life in our galaxy
B．there could be many habitable planets，but all in the"Goldilocks zone"
C．it won't be long before scientists find a habitable planet beyond Earth
D．alien life could exist on some other planets if it existed on Enceladus．

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．

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

7．Despite being used by 1.34 billion people each year，traveling on the Tube in London can actually be quite lonely．
One citizen，however，is trying to change this．"You get on the Tube and it's completely silent and it's weird（怪异的），"says Jonathan Dunne，who has started a worldwide dialogue after giving out badges （徽章） with the words"Tube chat？"last month，encouraging passengers in London to get talking to one another．"I handed out 500 badges during rush hour in a city of 8million，expecting most of them to be thrown away，but after about 24 hours it completely snowballed，"he says．Dunne and his"Tube chat"campaign have since been reported by media across the world，seeing TV interviews in Sweden，Brazil and the UK，as well as countless website，newspaper and magazine appearances．
Although Dunne says he's received mostly positive feedback，not everyone agrees with his idea．Londoner Brian Wilson responded with a campaign of his own，handing out 500 badges with the words"Don't even think about it"on them．Michael Robinson，24，a student from London，agrees．"Being on the Tube is the only peace and quiet some people get on their journeys to and from work．It doesn't need to be spoiled by people coming up and chatting to you，"he says．
"People assume that I just walk up and talk to strangers，which I don't，but it's been a great way to meet people you would never have normally spoken to，"Dunne says．
So if you ever end up using public transport in the West，why not say hello to the person next to you？Just make sure to check for a badge first．
