Hannah Taylor is a schoolgirl form Manitoba,Canada.One day, when she was five years old,she was walking with her mother in downtown Winnipeg.They saw a man 36 out of a garbage can.She asked her mother why he did that and her mother said that the man was homeless and hungry.Hannah was very 37 .She couldn't understand why some people had to live their without shelter or enough food.Hannah started to think about how she could 38 ,but,of course,there is not a lot one five-year-old can do to solve(解决)the problem of homelessness.
Later ,when Hannah attended school, she saw another homeless person. It was a woman, 39 an old shopping trolley（购物车）which was piled with 40 . It seemed that everything the woman owned was in them. This made Hannah very sad, and even more 41 to do something.She had been talking to her mother about the lives of homeless people 42 they first saw the homeless man. Her mother told her that if she did something to change the problem that made her sad, she wouldn’ t 43 as bad.
Hannah began to speak out about the homelessness in Manitoba and then in other provinces.She hoped to 44 her message of hope and awareness.She started the Ladybug Foudation ,an organization aiming at getting rid of bomekssacss. She began to “Big Bosses” lunches, where she would try to persuade local business Leaders to 46 to the cause.She also organized a fundraising(募捐)drive in “Ladybug Jars” to collect everyone`s spare change during “Make Change” month. More recently, the foundation began another 47 called National Red Scarf Day-a day when people donate $20 and wear red scarves in support of Canada`s 48 and homeless.
There is an emergency shelter in Winnipeg called “Hannah`s Place”,something that Hannah is very 49 of. Hannah`s Place is divided into several areas,providing shelter for people when it is so cold that 50 outdoors can mean death.In the more than five years since Hannah began her activities,she hasreceived a lot of 51 .
For example, she received the 2007 BRICKAward recognizing the 52 of young people to change the world. But 53 all this, Hannah still has the 54 life of a Winnipeg schoolgirl, except thatshe pays regular visits to homeless people.
Hannah is one ofmany examples of young people who are making a 55 in the world.You can,too!

It was a cold March day in High Point,North Carolina. The girls on the Wesleyan Academy softball were waiting fortheir next turns at bat during practice, stamping their feet to stay warm,Eighth-grader Taylor Bisbee shivered(发抖) a little as she watched her zxxk teammate Paris White play. Thetwo didn’t know each other well —Taylor had just moved to town a month or so before.
Suddenly, Paris fell to the ground,“Paris’s eye rolled back,” Taylor says. “She started shaking. I knew it was an emergency.”
It certainly was, Paris had suffered asudden heart failure. Without immediate medical care, Paris would die. “Doesanyone know CPR?”
CPR is a life-saving technique. To do CPR,you press on the sick person’s chest so that blood moves through the body andtakes oxygen to organs. Without oxygen the brain is damaging quickly.
Amazingly, Taylor had just taken a CPRcourse the day before. Still, she hesitated. She didn’t think she knew it wellenough. But when no one else came forward, Taylor ran to Paris and began doingCPR, “It was scary. I knew it was the difference between life and death,” saysTaylor.
Taylor’s swift action helped her teammatescalm down. One girl called 911. Two more ran to get the school nurse, who broughta defibrillator, an electronic devices(器械) that can shock the heart back into work. Luck stayed with them:Paris’ heartbeat returned.
“I know I was really lucky,” Paris say now. “Mostpeople don’t survive this. My team saved my life”
Experts say Paris is right: For a suddenheart failure, the single best chance for survival is having someone nearbystep in and do CPR quickly.
Today, Paris is back on the softball team.Taylor will apply to college soon. She wants to be a nurse. “I feel moreconfident in my actions now,” Taylor says. “I know I can act under pressure ina scary situation.”
(56)What happenedto Paris on a Marh day?A.She caught a bad cold.B. She had a sudden heartproblem.C.She was knocked down by a ball.D.She shivered terribly during practice
(57)Why does Parissay she was lucky?A.She made a worthy friend.B. She recovered from shock.C. Shereceived immediate CPR.D.She came back on the softball team.

Measles(麻疹), which once killed 450 children each year and disabled even more,was nearly wiped out in the United States 14 years ago by the universal use ofthe MMR vaccine(疫苗). But thedisease is making a comeback, caused by a growing anti-vaccine movement andmisinformation that is spreading quickly. Already this year, 115 measles caseshave been reported in the USA, compared with 189 for all of last year.
The numbers might sound small, but they arethe leading edge of a dangerous trend. When vaccination rates are very high, asthey still are in the nation as a whole, everyone is protected. This is called“herd immunity”, which protects the people who get hurt easily, including thosewho zxxk can’t be vaccinated for medical reasons, babies too young to getvaccinated and people on whom the vaccine doesn’t work.
But herd immunity works only when nearly thewhole herd joins in. When some refuse vaccination and seek a free ride,immunity breaks down and everyone is in even bigger danger.
That’s exactly what is happening in smallneighborhoods around the country from Orange County, California, where 22measles cases were reported this month, to Brooklyn, N.Y., where a 17-year-oldcaused an outbreak last year.
The resistance to vaccine has continued fordecades, and it is driven by a real but very small risk. Those who refuse totake that risk selfishly make others suffer.
Making things worse are state laws that makeit too easy to opt out(决定不参加) of what are supposed to be required vaccines for all childrenentering kindergarten. Seventeen states allow parents to get an exemption（豁免), sometimes just by signing apaper saying they personally object to a vaccine.
Now, several states are moving to tightenlaws by adding new regulations for opting out. But no one does enough to limitexemptions.
Parents ought to be able to opt out only forlimited medical or religious reasons. But personal opinions? Not good enough.Everyone enjoys the life-saving benefits vaccines provide, but they’ll existonly as long as everyone shares in the risks.
(63)The first twoparagraphs suggest that ____________.A．a small number of measles cases can start a dangerous trendB．the outbreak of measles attractsthe public attention C．anti-vaccine movement has its medical reasonsD．information about measles spreadsquickly
(64)Herd immunityworks well when ____________.A．exemptions are allowedB．several vaccines are used togetherC．the whole neighborhood is involved in D．new regulations are added to thestate laws
(65)What is themain reason for the comeback of measles?A．The overuse of vaccine.B．The lack of medical care.C．The features of measles itself.D．The vaccine opt-outs of some people.
(66)What is thepurpose of the passage?A．To introduce the idea of exemption.B．To discuss methods to cure measles.C．To stress the importance of vaccination. D．To appeal for equal rights inmedical treatment.
Hollywood’s theory that machines with evil(邪恶) minds will drive armies ofkiller robots is just silly. The real problem relates to the possibility thatartificial intelligence(AI) may become extremely good at achieving somethingother than what we really want. In 1960 a well-known mathematician NorbertWiener, who founded the field of cybernetics（控制论）, put it this way: “If we use, to achieve our purposes, a mechanicalagency with whose operation we cannot effectively interfere(干预), we had better be quite surethat the purpose which we really desire.”
A machine with a specific purpose hasanother quality, one that we usually associate with living things: a wish topreserve its own existence. For the machine, this quality is not in-born, noris it something introduced by humans; it is a logical consequence of the simplefact that the machine cannot achieve its original purpose if it is dead. So ifwe send out a robot with the single instruction of fetching coffee, it willhave a strong desire to secure success by disabling its own off switch or evenkilling anyone who might interfere with its task. If we are not careful, then,we could face a kind of global chess match against very determined, superintelligent machines whose objectives conflict with our own, with the realworld as the chessboard.
The possibility of entering into and losingsuch a match should concentrating the minds of computer scientists. Someresearchers argue that we can seal the machines inside a kind of firewall,using them to answer difficult questions but never allowing them to affect thereal world. Unfortunately, that plan seems unlikely to work: we have yet toinvent a firewall that is secure against ordinary humans, let alone superintelligent machines.
Solving the safety problem well enough tomove forward in AI seems to be possible but not easy. There are probablydecades in which to plan for the arrival of super intelligent machines. But theproblem should not be dismissed out of hand, as it has been by some AIresearchers. Some argue that humans and machines can coexist as long as theywork in teams—yet that isnot possible unless machines share the goals of humans. Others say we can just “switchthem off” as if super intelligent machines are too stupid to think of that possibility.Still others think that super intelligent AI will never happen. On September11, 1933, famous physicist Ernest Rutherford stated, with confidence, “Anyonewho expects a source of power in the transformation of these atoms is talkingmoonshine.” However, on September 12, 1933, physicist Leo Szilard invented theneutron-induced(中子诱导) nuclearchain reaction.
(67).Paragraph 1mainly tells us that artificial intelligence may .A. run out of human controlB.satisfy human’s real desiresC. command armies of killer robotsD. work fasterthan a mathematician
(68).Machines withspecific purposes are associated with living things partly because they mightbe able to .A. preventthemselves from being destroyedB achieve their original goals independentlyC.do anything successfully with given ordersD. beat humans in international chessmatches
(69)According tosome researchers, we can use firewalls to .A. help super intelligentmachines work betterB. be secure against evil human beingsC. keep machines frombeing harmedD. avoid robots’ affecting the world
(70)What does theauthor think of the safety problem of super intelligent machines?A. It willdisappear with the development of AI.B. It will get worse with humaninterference.C. It will be solved but with difficulty.D.It will stay for adecade.

Every animal sleeps,but the reason for thishas remained foggy.When lab rats are not allowed to sleep,they die within amonth. 71
One idea is that sleep helps us strengthennew memories. 72 We know that,while awake,fresh memories are recorded by reinforeing (加强)connections between braincells,but the memory processes that takeplace while we sleep have been unclear.
Support is growing for a theory thatsleep evolved so that connections between neurons(神经元)in the brain can be weakenedovernight,making room for fresh memories to from the next day. 73
Now we have the most direct evidence yet that he is right. 74 Thesynapses in the mice taken at the end ofa period of sleep were 18 per cent smaller than those taken beforesleep,showing that the connections between neurons weaken while sleeping.
If Tononi`s theory isright,it would explain why,when we miss a night`s,we find it harder the nextday to concentrate and learn new information-our brains may have smaller roomfor new experences.
Their research also suggests how we may build lasting memories overtime even though the synapscs become thinner.The team discovered that somesynapses seem to be protected and stayed the same size. 75 “You keep what matters,”Tononi says.A. Weshould also try to sleep well the night before.B. Ti’s as if the brain is preservingits most important memories.C. Similarly, when people go for a few days withoutsleeping, they get sick.D. The processes take place to stop our brains becomingloaded with memories.E. That’s why students do better in tests if they get achance to sleep after learning.F. “Sleep is the price we pay for learning,”says Giulio Tononi, who developed the idea.G. Tononi’s team measured the sizeof these connections, or synapses, in the brains of 12 mice.
