Today, when a fire breaks out, you can be sure a citizen with a cell-phone camera has posted it to Facebook or Twitter, or sent it to the media. But up to now, that citizen has not been able to easily send images and details of what is happening to the people who need it most: police, firefighters and building-security people who must respond, and whose ability to help is often measured in minutes, if not seconds.
That's about to change. A one-year old company called Elerts has developed a system that's designed to mobile and social technologies to speed the flow of information between citizens and emergency workers in time of danger. The system involves free mobile applications—iPhone and iPad app（應(yīng)用軟件）is available now—that eyewitnesses can use to report incidents and get public-safety warnings. And Elerts is offering a management console（控制臺）for security firms and universities to receive the reports and distribute warnings and instructions, like a map with the best evacuation route（疏散路線）.
The service is the brainchild of Chris Russo, deputy fire chief in the coastal town of Hull, Mass. As mobile communications sped up, he grew increasingly frustrated by his inability to communicate effectively with colleagues and the public, particularly with people who are at the scene and might be able to provide help.
"Remembering situations when communications failed puts a pit in my stomach," Mr. Russo says. Last summer, he was in a search at a beach for a missing boy, who went into a bathhouse but didn't come out. First responders feared an abduction （綁架） on the beach or shark attack. The child's mother, who didn't speak English well, was so sad that she couldn't remember what color shorts he had on. Mr. Russo had no photo of the child, and no ability to turn to beachgoers.
Two long hours later, the boy was spotted by a low-flying helicopter lost and alone on the beach crying—a lucky break. "If 5 percent of beachgoers had an app to receive a message and send in sightings of a lost boy, the happy ending might have come much sooner," Mr. Russo said.
小題1:What is the passage mainly about?
A．A moving story of Chris Russo．B．An app for reporting emergency．
C．A cell-phone instant service．D．An app for firm management．
小題2:What does the underlined part in Paragraph 4 most probably mean?
A．Makes me feel frustrated．B．Causes a stomachache．

小題3:We can infer from the passage that emergency workers ____．
A．have to carry out rescue work in minutes
B．must send images and details immediately
C．need images and detailed information badly
D．have to turn to Facebook and Twitter for details
小題4:The author takes Chris Russo's experience as an example to ____．
A．a(chǎn)dvertise his creativity in communication
B．show readers the working principle of the new system
C．make the passage more interesting to read
D．inform readers how Russo got the idea of the service

(2013·高考福建卷，B)Your glasses may someday replace your smartphone，and some New Yorkers are ready for the switch.Some in the city can’t wait to try them on and use the maps and GPS that the futuristic eyewear is likely to include.
“ I’d use it if I were hanging out with friends at 3 a．m.and going to the bar and wanted to see what was open，”said Walter Choo,40，of Fort Greene.
The smartphone­like glasses will likely come out this year and cost between $250 and $600，the Times said，possibly including a variation of augmented(增強(qiáng)的) reality，a technology already available on smartphones and tablets (平板電腦) that overlays information onto the screen about one’s surroundings.So，for example，if you were walking down a street，indicators would pop_up showing you the nearest coffee shop or directions could be plotted out and come into view right on the sidewalk in front of you.
“As far as a mainstream consumer product，this just isn’t something anybody needs，”said Sam Biddle，who writes for Gizmodo.com.“ We’re accustomed to having one thing in our pocket to do all these things，”he added，“and the average consumer isn’t gonna be able to afford another device (裝置) that’s hundreds and hundreds of dollars.”
9to5Google publisher Seth Weintraub，who has been reporting on the smartphone­like glasses since late last year，said he is confident that this type of wearable device will eventually be as common as smartphones.
“It’s just like smartphones 10 years ago，”Weintraub said.“A few people started getting emails on their phones，and people thought that was crazy.Same kind of thing.We see people bending their heads to look at their smartphones，and it’s unnatural，”he said.“ There’s gonna be improvements to that，and this a step there.”
小題1:One of the possible functions of the smartphone­like glasses is to ________.
A．program the opening hours of a bar
B．supply you with a picture of the future
C．provide information about your surroundings
D．update the maps and GPS in your smartphones
小題2:The underlined phrase“pop up”in the third paragraph probably means“ ________”．
A．develop rapidly
B．get round quickly
C．a(chǎn)ppear immediately
D．go over automatically
小題3:According to Sam Biddle，the smartphone­like glasses are ________.
A．necessary for teenagers
B．a(chǎn)ttractive to New Yorkers
C．a(chǎn)vailable to people worldwide
D．expensive for average consumers
小題4:We can learn from the last two paragraphs that the smartphone­like glasses ________.
A．may have a potential market
B．a(chǎn)re as common as smartphones
C．a(chǎn)re popular among young adults

In the past, going to a piano teacher was the most popular way to learn how to play the piano. You could get one-to-one teaching and have the opportunity to learn as much as the teacher knew. If you didn’t have private lessons, you could still learn the piano, but you would have to teach yourself. This was easy for some, but very difficult for most. However, with technology developing today, there is at last another way that you can take piano lessons. You can take an online course.
An online course is much cheaper than a private lesson. If a private lesson costs 30-40 dollars per week, just think about how quickly that adds up. You can take a whole online course in piano for just a fraction(小部分) of the money that you would spend on weeks of private lessons. Also, private lessons are usually only one hour per week. So you would have to wait for your next lesson to continue your learning. However, online piano courses are quite different.
With an online piano course, you can work at your own pace. You can also take as many lessons per week as you want, or go back and listen to your last lesson if you have forgotten anything. Most adults who want to learn how to play the piano enjoy being able to go back and listen to the lessons again.
Of course if you need someone to sit beside you and offer you immediate feedback(反饋) as you are playing, you might not get that from an online piano course. However, the lessons online can be viewed（觀看） at any time, or as often as you’d like, which means that you can get your own type of feedback from an online piano course.
小題1:This passage mainly tells us ______.
A．the disadvantages of the traditional ways of learning to play the piano
B．the differences between traditional piano courses and online courses
C．why people prefer online piano courses to traditional piano courses
D．the advantages of learning to play the piano through an online course
小題2:What does the underlined sentence in Paragraph 2 want to tell us?
A．That private piano lessons shouldn’t be that expensive.
B．That taking private piano lessons really costs a lot.
C．That not everyone can afford to take piano lessons.
D．That the price for private piano lessons has increased greatly.
小題3:How did the writer make his points clear?
A．By giving detailed data.
B．By giving many examples
C．By writing about his own experiences
D．By comparing with the old ways.

Popeye the Sailor first became a popular cartoon in the 1930s. the sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.
Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.
People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.
Today, we know that the little iron in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.
It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.
小題1:A good title for this reading passage is______.
A．Popeye the Sailor
B．The Truth About Spinach
C．A Mistake with Numbers
D．Folic Acid Makes You Strong
小題2:Why did many people eat spinach after they saw Popeye the Sailor?
A．People liked folic acid.
B．They thought Popeye was funny.
C．Spinach had a lot of iron.
D．They thought spinach made them strong.
小題3:A research group told people that spinach______.
A．made Popeye strong
B．was a green vegetable
C．had less iron than other green vegetables
D．had more iron than other green vegetables
小題4:The reading passage says that perhaps Popeye got his strength from______.

Science Daily—Kids may roll their eyes when their mothers asks them about their school day, but answering her may actually help them learn. New research from Vanderbilt University reveals that children learn the solution to a problem best when they explain it to their mom.
“We knew that children learn well with their moms or with a peer, but we did not know if that was because they were getting feedback and help,” Bethany Rittle-Johnson, the study’s lead author and assistant professor of psychology at Vanderbilt’s Peabody College of education and human development, said. “In this study, we just had the children’s mothers listen, without providing any assistance. We’ve found that by simply listening, a mother helps her child learn.”
Rittle-Johnson believes the new finding can help parents better assist their children with their schoolwork, even when they are not sure of the answer themselves. Although the researchers used children and their mothers in the study, they believe the same results will hold true whether the person is the child’s father, grandparent, or other familiar persons.
“The basic idea is that it is really effective to try to get kids to explain things themselves instead of just telling them the answer,” she said. “Explaining their reasoning, to a parent or perhaps to other people they know, will help them understand the problem and apply what they have learned to other situations. We saw that this simple act of listening by mom made a difference in the quality of the child’s explanations and how well they could solve more difficult problems later on.
小題1:According to the passage, a mom had better ________.
A．give a kid some help when he is explaining his problem
B．just listen while a kid is explaining his problem
C．work together with a kid toward the solution to a problem
D．leave a kid alone when he meets a problem at school
小題2: If she wants to help a child with his schoolwork, a mom ________.
A．should know the answer to a problem first
B．should pay attention to the child’s feedback.
C．may not know the answer herself
D．should not interrupt the child
小題3:Who will be the least help to a kid when he is explaining, according to Rittle-Johnson?
A．The kid’s mom.
B．The kid’s grandmother.
C．A peer.
D．A relative the kid doesn’t know.
小題4:Which of the following best gives the main idea of the passage?
A．Children learn better when their mom is hearing their explaining.
B．Children learn better if they find the solution to a problem themselves.
C．Parents should not provide any assistance to their children’s schoolwork.
D．A mom should listen more to their children when they have problems at school.

Make Up Your Mind to Succeed
Kind-hearted parents have unknowingly left their children defenseless against failure．The generation (age) born between 1980 and 2001 grew up playing sports where scores (marks) and performance (show) were played down because “everyone's winner.” And their report cards sounded more positive than ever before．As a result, Stanford University professor Carol Dweck, PhD, calls them “the overpraised generation.”
Dweck has been studying how people deal with failure for 40 years．Her research has led her to find out two clearly different mind-sets that have a great effect on how we react to it．Here's how they work:
　　A fixed mind-set is grounded in the belief that talent is genetic – you're a born artist, point guard, or numbers person．The fixed mind-set believes it's sure to succeed without much effort and regards failure as personal shame．When things get difficult, it's quick to blame (liability), lie, and even stay away from future difficulties.
　 On the other hand, a growth mind-set believes that no talent is entirely heaven-sent and that effort and learning make everything possible．Because the ego (自尊) isn't on the line as much, the growth mind-set sees failure as a chance rather than shame．When faced with a difficulty, it's quick to rethink, change and try again．In fact, it enjoys this experience.
　　We are all born with growth mind-sets．(Otherwise, we wouldn't be able to live in the world.) But parents, teachers, and instructors often push us into fixed mind-sets by encouraging certain actions and misdirecting praise．Dweck's book, Mind-set: The New Psychology of Success, and online instructional program explain this in depth．But she says there are many little things you can start doing today to make sure that your children, grandchildren and even you are never defeated by failure.
小題1:What does the author think about the present generation?
A．They don't do well at school.
B．They are often misunderstood.
C．They are eager to win in sports
D．They are given too much praise.
小題2:A fixed mind-set person is probably one who ___ .
A．doesn't want to work hard
B．cares a lot about personal safety
C．cannot share his ideas with others
D．can succeed with the help of teachers
小題3:What does the growth mind-set believe?
A．Admitting failure is shameful.
B．Talent comes with one's birth.
C．Getting over difficulties is enjoyable.
D．Scores should be highly valued.

Bottled water has become the choice for people who are healthy and thirsty. Bottled water is all over the world. But some say the planet’s health, and people’s health may be suffering from it.
The idea that bottled water is safer for humans may not be true. The Natural Resources Defense Council of America said, “There is no promise that because water comes out of a bottle, it is cleaner or safer than water from the tap.” Another New York City-based action group added that some bottled water is “really just tap water in a bottle—sometimes more clean, sometimes not.”

It is not proven that bottled water is better than tap water. Nick Reeves from the Chartered Institution of Water and Environmental Management said, “The high mineral content (含量) of some bottled water makes them not good for feeding babies and young children.” Also, most bottled water doesn’t have fluoride (氟化物), which can make teeth stronger. Kids are drinking more bottled water and less fluoridated tap water, and some say that’s behind the recent rise in bad teeth.
Storing is another problem. Placed near heat, the plastic bottles can produce bad chemicals (化學(xué)物質(zhì)) into the water.
According to the Environmental Protection Agency, some 2.7 million tons of plastic are used worldwide to bottle water each year. The plastic can take between 400 and 1,000 years to break down.
In terms of energy use, plastic bottles are also not cheap. One report said that if water and soft drink bottlers had used 10 percent recycled materials in their plastic bottles, they would have saved about 72 million gallons of gas.
So, if you are worried about the effect of bottled water on the Earth, you can take the following steps.
● Drink from your tap. Unless your government warns against this, it should be fine.
● Get a container (容器). Carry your tap water in a steel or a lined drinking container, and clean it between uses.
● Keep it cool. Don’t drink from a bottle that has been sitting in the sun, don’t store it near chemicals, and don’t reuse plastic bottles.
● Choose glass containers over plastic if possible. When finished, recycle!
小題1:What is the main idea of the article?
A．Drinking tap water is the only choice for people.
B．Glass containers are better than plastic bottles.
C．Plastic bottles are harmful to the environment.
D．Bottled water may not be as good as we think.
小題2:What can we learn about plastic bottles from the article?
A．They break down in less than 300 years.B．They can be used for many other things.
C．They are a risk to the environment.D．They are cheap to make.
小題3:According to the article, we can know that bottled water is __________.
A．no problem for the environmentB．more expensive than tap water
C．a(chǎn)lways safer than tap waterD．better for babies
小題4:Which of the following about tap water is NOT mentioned in the article?
A．There are a lot of problems storing tap water.
B．Bottled water can be just tap water in a bottle.
C．It may be better for your teeth.
D．It may contain fluoride.

What if I took that big jump on my bike?What’s the worst thing that could happen if I go out at midnight?Should try smoking?The teen years can play out like a choose-your-own-adventure novel.
Teenagers must act on an endless parade of choices.Some choices.including smoking.Come with serious consequences.As a result, adolescents often find themselves trapped between their impulsive tendencies（-Just try it!)and their newfound ability to make well-informed and logical choices（-Wait, maybe that’s not such a good idea!）.
So what makes the teenager’s brain so complex? What drives adolescents-more than any other age group-to sometimes make rash or questionable decisions?

Experts Experts believe that this tendency marks a necessary period in teen development.The process helps prepare teenagers to confront the world on their own. It is something all humans have evolved to experience-yes, teens everywhere go through this exploratory period.Nor is it unique to people:Even laboratory mice experience a similar stage during their development.
For example，laboratory experiments show that young mice stay close by their mothers for safety. As mice grow．their behavior does too．“When they reach puberty，they’re like，‘I’m gonna start checking out how this environment looks without my mom，…explains Beatriz Luna,of the University of Pittsburgh．
As a developmental cognitive neuroscientist，Luna studies those changes that occur in the brain as children develop into adults．She and other researchers are showing how the teen experience can lead to powerful advantages later in life．Take mice again：Young mice that explore most tend to live longest——that is，unless a cat eats them，Luna adds．
