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?
If you have ever thought that the choices teenagers make are all about exploring and pushing limits, you are on to something. 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．

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．
C．Arouses my interest．D．Leaves a hole in my stomach．
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．advertise 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

I am a strong believer that if a child is raised with approval (準允), he learns to love himself and will be successful in his own way. Several weeks ago, I was doing homework with my son in the third grade and he kept standing up from his chair to go over the math lines. I kept asking him to sit down, telling him that he would concentrate better. He sat but seconds later, as if he didn’t even notice he was doing it, he got up again. I was getting frustrated (受挫), but then it hit me. I started noticing his answers were much quicker and accurate when he stood up. Could he be more absorbed while standing up?
This made me start questioning myself and what I had been raised to believe. I was raised to believe that a quiet, calm child was a sure way to success. This child would have the willpower to study hard, get good grades and become someone important in life.
Now those same people perhaps come to realize that their kids are born with their own sets of DNA and personality qualities, and all you can do is loving and accepting them. As parents, throughout their growing years and beyond that, we need to be our kids’ best cheerleaders, guiding them and helping them find their way.
I have stopped asking my son to sit down and concentrate. Obviously, he is concentrating just in his own way and not mine. We need to learn to accept our kids’ ways of doing things. Some way may have worked for me but doesn’t mean we need to carry it through generations. There is nothing sweeter than being personal and unique (獨特的). It makes us free and happy and that’s just the way I want my kids to live their own life. 
小題1:Time and again the author got his son seated in order to make him ______.
A．work fastB．go politeC．stay relaxedD．keep attentive
小題2:The underlined “it” (in the first paragraph) probably refers to ______.
A．his son’s doing better while standing up
B．his failure in keeping his son under control
C．his own experience as a school boy
D．his disappointment with his active child
小題3:By this passage, the author attempts to tell other parents to ______.
A．correct their kids’ manners from the early ages
B．respect and trust their kids’ ways of behaviors
C．develop a good relationship with their children
D．guarantee their children’s freedom at home
小題4:Which of the following would be the best title of the passage?
A．Parental help with teens’ study
B．Adult influence on teen growth
C．Kids’ success in their own styles
D．Friendship between generations

About ten men in every hundred suffer from color blindness in some way. Women are luckier, only about one in two hundred if affected in this matter. Perhaps, after all, it is safer to be driven by a woman.
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person can’t tell the differences between blue and green. In rare cases an unlucky man sees everything in shades of green--- a strange world in deed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions very small things called “cones”. These help us see in a bright day and tell the differences between colors. There are also millions of “rods”, but these are used for seeing when it is nearly dark. They show us shapes(形狀) but not color. Some insects have favorite colors. Mosquitoes like blue but do not like yellow. A red light will not attract insects but a blue lamp will. In similar way human being also have favorite colors. Yet we are lucky. With the aid of cones in our eyes we can see many beautiful colors by day and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
小題1:The passage is mainly about ______.
A．color and its surprising effects on drivers
B．women being luckier than man in that fewer of them are color blind
C．danger caused by color blindness
D．color blindness and how our eyes tell different colors and shapes
小題2:According to the passage, with the help of “cones” we can _____.
A．tell different colorsB．see in weak light
C．tell different shapesD．tell orange from yellow
小題3:Why do some people say it is safer to be driven by women?
A．Women are more careful.
B．There are fewer color blind women.
C．Women are fonder of driving than men.
D．Women are weaker but quicker in thinking.
小題4:Which of the following statements about color blind people is true?
A．Not all of them have the same problem in recognizing colors.
B．None of them can see deep red but all can tell blue from green.
C．None of them can tell blue from green but all can see deep red.
D．All of them are lucky enough to see everything in shades of green.

400-year-old plants from the Little Ice Age were brought back to life, which could help us understand how the Earth will deal with climate change.
Moss(蘚類植物) found buried beneath the Teardrop glacier(冰川) on Ellesmere Island in Canada has been brought back to life. Findings suggest that these plants could help repopulate regions exposed by melting ice caps. Plants that were buried beneath thick ice in Canada more than 400 years ago and were thought to have frozen to death have been brought back to life by Canadian scientists.
Samples of the moss plant, covered by the glacier during the Little Ice Age of 1550 to 1850 AD, were replanted in a lab at the University of Alberta and grew new stems(莖). Researchers now think these findings can give indication as to how regions can recover as the ice covering them melts.
Biologist Dr. Catherine La Farge and her team at the University of Alberta were exploring the region around the Teardrop glacier on Ellesmere Island. Ice on Ellesmere Island region has been melting at around four meters each year for the past nine years. This means that many areas of land that were previously covered by ice have since been exposed. Many ecosystems that were thought to have been destroyed during the Little Ice Age between 1550 and 1850 AD can now be studied, including many species that have never been studied before.
While examining an exposed area of land, La Farge and her team discovered a small area of moss called Aulacomnium turgidum. It is a type of bryophyte(苔蘚類植物) plant that mainly grows across Canada, the US and the Highlands of Scotland.
Dr La Farge noticed that the moss had small patches of green stems, suggesting it is either growing again or can be encouraged to repopulate. Dr La Farge told the BBC, “When we looked at the samples in detail and brought them to the lab, I could see some of the stems actually had new growth of green branches, suggesting that these plants are growing again, and that blew my mind. When we think of thick areas of ice covering the landscape, we’ve always thought that plants have to come from refugia(瀕絕生物保護區(qū)), never considering that land plants come from underneath a glacier. It’s a whole world of what’s coming out from underneath the glacier that really needs to be studied. The ice is disappearing pretty fast. We really have not examined all the biological systems that exist in the world; we don’t know it all.”
Dr La Farge took samples of the moss and, using carbon-dating techniques, discovered that the plants date back to the Little Ice Age. Dr La Farge’s team took the samples, planted them in dishes full of nutrient-rich potting soil and fed them with water.
The samples were from four separate species including Aulacomnium turgidum, Distichium capillaceum, Encalypta procera and Syntrichia ruralis. The moss plants found by Dr La Farge are types of bryophytes. Bryophytes can survive long winters and regrow when the weather gets warmer.
However, Dr La Farge was surprised that the plants buried under ice have survived into the twenty-first century. Her findings appear in proceedings（論文集）of the National Academy of Sciences.
小題1:Dr La Farge’s research is of great importance to ________.
A．knowing what the plants during the Little Ice Age were like
B．understanding how ecosystems recover from glaciers.
C．regrowing many species that have been destroyed before.
D．figuring out the effects of melting ice caps on moss.
小題2:The underlined part “blew my mind” in Paragraph 6 can best be replaced by “________”.
A．surprised meB．greatly frightened me
C．put my doubt out of my mindD．was exactly what I had in my mind
小題3:According to the passage, Aulacomnium turgidum ________.
A．lives better in small groups
B．is very active in hot weather
C．is strong enough to survive coldness
D．is chosen from Canadian refugia
小題4:Which of the following would be the best title for the passage?
A．Bryophyte ecology is greatly affected by climate change.
B．400-year-old moss’s survival is a mystery to solve.
C．Moss in ancient times was discovered in Canada.
D．400-year-old plants were brought back to life.

My house is made of wood, glass and stone. It is also made of software.
If you come to visit, you'll probably be surprised when you come in: Someone will give you an electronic PIN to wear. The PIN tells the house who you are and where you are. The house uses this information to give you what you need. When it's dark outside, the PIN turns on the lights near you, and then turns them off as you walk away from them. Music moves with you, too. If the house knows your favorite music, it plays it for you. The music seems to be everywhere, but in fact other people in the house hear different music or no music. If you get a telephone call, only the nearest telephone rings.
Of course, you are also able to want something. There is a home control console (控制臺) which is a small machine that turns things on and off around you.
The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you the key to my car, you can use my car. The car works for you because you have the key. My house works for you because you wear the PIN or hold the console.
I believe that in ten years from now, most new houses will have the systems that I've put in my house. The systems will probably be even bigger and better than the ones I've got.
I like to try new ideas. I know that some of my ideas will work better than others'. But I hope that one day I will stop thinking of these systems as new, and ask myself instead, ”How did I live without them?”
小題1:The writer’s house is made of the following EXCEPT_________.
A．bamboo B．woodC．glassD．software
小題2:What is the writer most likely to be according to the passage?
A．An IT expert.B．A famous doctor.

A few degrees can make a big difference when it comes to food storage. Foods can go bad if they get too warm. But for many of the world’s poor, finding a good way to keep food cool is difficult. Refrigerators are costly and they need electricity.
Yet spoiled food not only creates health risks but also economic losses. Farmers lose money when they have to throw away products that they cannot sell quickly.
But in nineteen ninety-five a teacher in northern Nigeria named Mohammed Bah Abba found a solution. He developed the “Pot-in-Pot Preservation/Cooling System.” It uses two round containers made of clay. A smaller pot is placed inside a larger one. The space between the two pots is filled with wet sand. The inner pot can be filled with fruit, vegetables or drinks. A wet cloth covers the whole cooling system.
Food stored in the smaller pot is kept from spoiling through a simple evaporation(蒸發(fā)) process. Water in the sand between the two pots evaporates through the surface of the larger pot, where drier outside air is moving.
The evaporation process creates a drop in temperature of several degrees. This cools the inner pot and helps keep food safe from harmful bacteria. Some foods can be kept fresh this way for several weeks.
People throughout Nigeria began using the invention. And it became popular with farmers in other African countries. Mohammed Bah Abba personally financed the first five thousand pot-in-pot systems for his own community and five villages nearby.
In two thousand, the Rolex Watch Company of Switzerland honored him with the Rolex Award for Enterprise. This award recognizes people trying to develop projects aimed at improving human knowledge and well-being. A committee considers projects in science and medicine, technology, exploration and discovery, the environment and cultural history. Winners receive financial assistance to help develop and extend their projects.
小題1:Which is the best title of the passage?
A．A Few Degrees can Make a Big Difference for Storage
B． A Cool Way to Keep Food from Spoiling
C． Spoiled Food Creates Health Risks and Economic Losses
D． The Evaporation Process Creates a Drop in Temperature
小題2:What does the third paragraph mainly talk about?
A．the structure of the invention
B．the usage of the invention
C．the cost of the invention
D．the inspiration of the invention
小題3:What is it that essentially keeps the food in the container from spoiling?
A．the wet cloth covering the cooling system.
B．the moving drier air outside the container
C．the wet sand between the containers
D．a drop in temperature by evaporation
小題4:According to the passage, where can we possibly see the invention?
A．rich and advanced families
B．scientific experiment laboratory
C．poor and underdeveloped area
D．supermarket needing to store goods
小題5:We can know from the passage that Mohammed Bah Abba ____________.

There are various aspects that go into making a successful school, and success can be measured in various ways. Often, the teachers are praised for a school’s success and blamed for its failure. Yet, in order for a school to be effective, it must be a place where teaching and learning can easily take place, and that requires the hard work of more than just educators. Students must take learning into their own hands and feel as if what they are doing is as important as it actually is. This can only be done with the cooperation of every adult that is involved in the students’ life. Some of these individuals often go unnoticed, yet the role they play in the students’ lives is immeasurable.
In the school, administrative assistants greet students at the start of the day and answer a large quantity of questions. When an assistant remembers a student’s name or even something special about that student, it communicates to him that he is cared for. The assistant can also give that extra encouragement for a student to make better choices, especially when they are visiting the principal’s office.
Meanwhile, though cafeteria workers have a short space of time to interact with students, they can make a big difference as well. Beyond meeting nutritional needs, cafeteria workers may also on occasion meet the emotional needs of the students they serve. Students benefit from positive interaction with adults, and cafeteria workers may give that extra bit of encouragement that a child needs.
Custodians (管理員) are usually underappreciated for what they offer to schools. They have to be knowledgeable about everything from cleaning to fixing the most intricate (復雜的) tools. They get to school early in the morning before teachers arrive and lock up late at night after the last student has left from the after-school event. They also make sure teachers are equipped with the necessary items and prepare the rooms so that they are ready for learning. A great custodian also gives that kind word or extra smile to that student who needs it most.
小題1:The purpose of the passage is to _______.
A．emphasize the role teachers play in a school
B．highlight the contributions of other staff at school besides teachers.
C．tell us who make the greatest contributions to a school
D．explain what contributes to the success of a student
小題2:If an assistant remembers a student’s name, the student will feel that _________.
A．he is paid particular attention toB．he is special
C．he has done something wrongD．he has made progress in study
小題3:Which of the following is TRUE about cafeteria workers?
A．It’s enough for them to cook for the students.
B．It’s hard for them to interact with the students.
C．They have the most interaction with students at school.
D．They can also meet the emotional needs of the students.
小題4:How does the author feel about the staff mentioned in the text?
A．Disappointed.B．Dissatisfied.C．Appreciative.D．Doubtful.

Not long ago, many people believed that babies only wanted food and to be kept warm and dry. Some people thought babies were not able to learn things until they were five or six months old.
Yet doctors in the United States say babies begin learning on their first day of life. The Eunice Kennedy Shriver National Institute of Child Health and Human Development is a federal government agency. Its goal is to determine which experiences can influence healthy development in people.
Researchers at the institute note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other people.
The researchers say this ability to learn exists in a baby even before birth. They say newborn babies can recognize and understand sounds they heard while they were still developing inside their mothers.
Another study has suggested that low birth weight babies with no evidence of disability may be more likely than other children to have physical and mental problems.
American researchers studied almost five hundred boys and girls. They were born in, or admitted to, one of three hospitals in New Jersey between 1984 and 1987. At birth, each child weighed fewer than two thousand grams.
The boys and girls had an average age of sixteen at the time of the study. They were asked to complete intelligence and motor skill tests in their homes. Their test results were compared with those of other children their age.
小題1:According to the passage, some people used to think that babies began to learn _________.
A．on their first day of lifeB．even before they were born
C．before five or six months oldD．at or after five or six months old
小題2:Babies learn to connect and communicate with other people through_____________.
A．smilesB．criesC．facial expressionsD．body language
小題3:The Eunice Kennedy Shriver National Institute of Child Health and Human Development tries to find out ________.
A．what affects people’s healthy development
B．what influences babies’ learning ability
C．how to cure some children’s health problems
D．how to develop children’s learning ability
小題4:What will be mentioned in the following passage?
A．The evaluation method of the tests.
B．The cause of low birth weight babies.
C．The result of the intelligence and motor skill tests.
D．The evidence proving babies began to learn before birth.
