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.

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 Foundation,an organisation aiming at getting rid of homelessness. She began to 45 “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 “MakeChange” month. More recently, the foundation began another 47 calledNational 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.

The girls on the Wesleyan Academy softball were waiting for their 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 teammate Paris White play. The two 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 a sudden heart failure. Without immediate medical care, Paris would die. “Does anyone 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 and takes oxygen to organs. Without oxygen the brain is damaging quickly.Amazingly, Taylor had just taken a CPR course the day before. Still, she hesitated. She didn’t think she knew it well enough. 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 teammates calm down. One girl called 911. Two more ran to get the school nurse, who brought a 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. “Most people don’t survive this. My team saved my life.” Experts say Paris is right: For a sudden heart failure, the single best chance for survival is having someone nearby step 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 more confident in my actions now,” Taylor says. “I know I can act under pressure ina scary situation.”56.What happened to Paris on a March day?A.She caught a bad cold.B. She had a sudden heart problem.C.She was knocked down by a ball.D.She shivered terribly during practice57.Why does Paris say she was lucky?A.She made a worthy friend.B. She recovered from shock.C. She received immediate CPR.D.She came back on the softball team.58.Which of the following words can best describe Taylor?A.Enthusiastic and kind.B.Courageous and calm.C.Cooperative and generous.D.Ambitious and professional.BInspiring young minds!TOKNOW Magazine is a big hit in the world of children’s publishing, bringing a unique combination of challenging ideas and good fun to young fans every month.Sounds too good to be true?Take a look online—evidence shows that thousands of teachers and parents know a good thing when they see it and recommend TOKNOW to their friends.Happy Birthday All Year!What could be more fun than a gift that keeps coming through the letterbox every month?

But the disease is making a comeback, caused by a growing anti-vaccine movement and misinformation that is spreading quickly. Already this year, 115 measles cases have been reported in the USA, compared with 189 for all of last year.The numbers might sound small, but they are the leading edge of a dangerous trend. When vaccination rates are very high, as they 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 those who can’t be vaccinated for medical reasons, babies too young to get vaccinated and people on whom the vaccine doesn’t work.But herd immunity works only when nearly the whole 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 small neighborhoods around the country from Orange County, California, where 22measles cases were reported this month, to Brooklyn, N.Y., where a 17-year-old caused an outbreak last year.The resistance to vaccine has continued for decades, and it is driven by a real but very small risk. Those who refuse to take that risk selfishly make others suffer.Making things worse are state laws that make it too easy to opt out(决定不参加) of what are supposed to be required vaccines for all children entering kindergarten. Seventeen states allow parents to get an exemption(豁免), sometimes just by signing a paper saying they personally object to a vaccine.Now, several states are moving to tighten laws by adding new regulations for opting out. But no one does enough to limit exemptions.Parents ought to be able to opt out only for limited medical or religious reasons. But personal opinions? Not good enough.Everyone enjoys the life-saving benefits vaccines provide, but they’ll exist only as long as everyone shares in the risks.63.The first two paragraphs suggest that ____________.A.a small number of measles cases can start a dangerous trendB.the outbreak of measles attracts the public attentionC.anti-vaccine movement has its medical reasonsD.information about measles spreads quickly64.Herd immunity works well when ____________.A.exemptions are allowed B.several vaccines are used togetherC.the whole neighborhood is involved in D.new regulations are added to the state laws 65.What is the main 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 the purpose 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 in medical treatment.DHollywood’s theory that machines with evil(邪恶) minds will drive armies of killer robots is just silly. The real problem relates to the possibility that artificial intelligence(AI) may become extremely good at achieving something other than what we really want. In 1960 a well-known mathematician Norbert Wiener, who founded the field of cybernetics(控制论), put it this way: “If we use, to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere(干预), we had better be quite sure that the purpose which we really desire.”A machine with a specific purpose has another quality, one that we usually associate with living things: a wish top reserve its own existence. For the machine, this quality is not in-born, nor is it something introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead. So if we send out a robot with the single instruction of fetching coffee, it will have a strong desire to secure success by disabling its own off switch or even killing 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, super intelligent machines whose objectives conflict with our own, with the real world as the chessboard.The possibility of entering into and losing such a match should concentrating the minds of computer scientists. Some researchers argue that we can seal the machines inside a kind of firewall,using them to answer difficult questions but never allowing them to affect the real world. Unfortunately, that plan seems unlikely to work: we have yet to invent a firewall that is secure against ordinary humans, let alone super intelligent machines.Solving the safety problem well enough to move forward in AI seems to be possible but not easy. There are probably decades in which to plan for the arrival of super intelligent machines. But the problem should not be dismissed out of hand, as it has been by some AI researchers.
