A new study has found that it may be possible to train people to be more intelligent, increasing the brainpower they had at birth.
Until now,it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience—what psychologists call fluid intelligence—is innate and cannot be taught(though people can raise their grades on tests of it by practicing).
But in the new study,researchers describe a method for improving this skill,along with experiments to prove it works.
The key, researchers found, was carefully structured training in working memory—the kind that allows memorization of a telephone number just long enough to dial it.This type of memory is closely related to fluid intelligence,so the researchers reasoned that improving it might lead to improvements in fluid intelligence.
First they measured fluid intelligence of volunteers using standard tests.Then they trained each in a complicated memory task—the child’s card game,in which they had to recall a card they saw and heard.During the course, they needed to ignore irrelevant items, monitor ongoing performance,manage two tasks at the same time and connect related items to one another in space and time.
The four groups experienced a half-hour of training daily for 8, 12, 17 and 19 days, respectively.To make sure they were not just improving their test-taking skills,the researchers compared them with control groups that took the tests without the training.
The results, published Monday in The Proceedings of the National Academy of Sciences,were striking.Improvement in the trained groups was a lot greater.Moreover,the longer they trained, the higher their scores were.All performers,from the weakest to the strongest,showed significant improvement.
“Our results show you can increase your intelligence with proper training.” said Dr Jaeggi, a co-author of the paper.“No one knows how long the gains will last after training stops,” he added, “and the experiment’s design did not allow the researchers to determine whether more training would continue to produce further gains.

Do you want to live with a strong sense of peacefulness,happiness,goodness,and selfrespect?The collection of happiness actions broadly categorized (把……歸類) as “honor” help you create this life of good feelings.
Here’s an example to show how honorable actions create happiness.
Say a store clerk fails to charge us for an item.If we keep silent,and profit from the clerk’s mistake,we would drive home with a sense of sneaky (暗中的) excitement.Later we might tell our family or friends about our good fortune.On the other hand,if we tell the clerk about the uncharged item,the clerk would be grateful and thank us for our honesty.We would leave the store with a quiet sense of honor that we might never share with another soul.
Then,what is it to do with our sense of happiness?
In the first case,where we don’t tell the clerk,a couple of things would happen.Deep down inside we would know ourselves as a type of thief.In the process,we would lose some peace of mind and selfrespect.We would also demonstrate that we cannot be trusted,since we advertise our dishonor by telling our family and friends.We damage our own reputations by telling others.In contrast,bringing_the_error_to_the__clerk’s__attention causes different things to happen.Immediately the clerk knows us to be honorable.Upon leaving the store,we feel honorable and our selfrespect is increased.Whenever we take honorable actions we gain the deep internal rewards of goodness and a sense of nobility.
There is a beautiful positive cycle that is created by living a life of honorable actions.Honorable thoughts lead to honorable actions.Honorable actions lead us to a happier existence.And it’s easy to think and act honorably again when we’re happy.While the positive cycle can be difficult to start,once it’s started,it’s easy to continue.Keeping on doing good deeds brings us peace of mind,which is important for our happiness.
【小題1】According to the passage,the positive action in the example contributes to our________.
A.selfrespect | B.financial rewards |
C.a(chǎn)dvertising ability | D.friendly relationship |
A.lying | B.stealing |
C.cheating | D.a(chǎn)dvertising |
A.telling the truth to the clerk |
B.offering advice to the clerk |
C.a(chǎn)sking the clerk to be more attentive |
D.reminding the clerk of the charged items |
A.We’ll be very excited. |
B.We’ll feel unfortunate. |
C.We’ll have a sense of honor. |
D.We’ll feel sorry for the clerk. |
A.How to Live Truthfully |
B.Importance of Peacefulness |

When I started my career in management, I was really green, but I always tried to stay positive on the job. I was working for a new company that was having a difficult time with its customers. Actually, at one point my General Manager told me he liked me and suggested I should start looking for a new job as we were about to lose our only order. Every day we faced people leaving the company, customers complaining, and upper management preparing to close the place.

The young man arrived on the Massachusetts beach early carrying a radio, a shovel(鐵鍬), and a strange set of tools: a brick layer’s trowel, a palette knife, spatulas, spoons, and a spray bottle.
He walked down near the water — the tide(潮水) was out — and switched on the radio to listen to soft rock. Then he shoveled wet sand into a pile nearly four feet high and as many feet across. Then he created a square shape.
After that, he set to work with palette knife, spatulas, and spoons. He shaped a splendid tower, topped walls, fashioned beautiful bay windows, and carved (雕刻)out a big front gate.
The man knew his sand. He smoothly finished some surfaces and carved artistic designs on others. As the shapes began to dry, he gently kept them slightly wet with water from the spray bottle, in case they might break in the wind.
All this took hours. People gathered. At last he stood back, obviously satisfied with a castle worthy of the Austrian countryside or Disneyland.
Then he gathered his tools and radio and moved them up to drier sand. He had known for a while what many in the crowd still ignored: the tide was coming in. Not only had he practiced his art with confidence and style, he also had done so against a powerful, irresistible(不可抵抗的) deadline.
As the crowd looked on, water came at the base of the castle. In minutes it was surrounded. Then the rising flood began to eat into the base, walls fell, the tower fell, and finally the gate fell. More minutes passed, and small waves erased bay windows — soon no more than a small part was left.
Many in the crowd looked terribly sad; some voiced fear and discouragement. But the man remained calm. He had, after all, had a wonderful day, making beauty out of nothing, and watching it return to nothing as time and tide moved on.
【小題1】In this passage, why did the young man start early in the day?
A.He needed the sun to help dry the sand. |
B.It gave plenty of time for the crowd to gather. |
C.He knew the tide was out on this particular morning. |
D.It was easier to begin his work with only a few people around. |
A.It is time to begin working. |
B.It is the end of a day’s work. |
C.It is the busiest time of the day. |
D.It is time for lookers-on to leave. |
A.They were disappointed to see the art ruined. |
B.They tried their best to save the sand castle. |
C.They were nervous about their own belongings. |
D.They helped the artist finish the castle. |
A.payment for his work |
B.personal satisfaction |
C.popularity as an artist |
D.a(chǎn)ttention from the crowd |

We all know what it is like to be unable to turn your head because of a cold in the muscles of your neck, or because an unexpected twist has made your neck ache. The slightest move makes you jump with pain. Nothing could be worse than a pain in the neck.
That is why we use the phrase to describe some people who give you the same feeling. We have all met such people.
One is the man who always seems to be clapping his hands—often at the wrong time—during a performance in the theater. He keeps you from hearing the actors.
Even worse are those who can never arrive before the curtain goes up and the play begins. They come hurrying down to your row of seats. You are comfortably settled down, with your hat and heavy coat in your lap. You must stand up to let them pass. You are proud of yourself-control after they have settled into their seats…Well, what now…God, one of them is up again. He forgot to go to the men’s room, and once more you have to stand up, hanging on to your hat and coat to let him pass. Now, that is “a pain in the neck”.
Another, well—known to us all, is the person sitting behind you in the movies. His mouth is full of popcorn ; he is chewing loudly, or talking between bites to friends next to him. None of them remain still. Up and down, back and forth, they go—for another bag of popcorn, or something to drink.
Then, there is the man sitting next to you at lunch, smoking. He wants you to enjoy it too, and blows smoke across your food into your mouth.
We must not forget the man who comes into a bus or subway and sits down next to you, just as close as you will let him. You are reading the newspaper and he gets closer so that he can read the paper with you. He may even turn the paper to the next page before you are ready for it.
We also call such a person a “rubber neck”, always getting close to where it does not belong, like neighbors who watch all your visitors. They enjoy learning about your personal business. People have a strong dislike for “rubber necks”. They hate being watched secretly.
【小題1】Where can you find this passage?
A.In a medicine dictionary. | B. in a kids’ story book. |
C.In a social science book. | D.In a science textbook. |
A.disturbed. | B.bored. | C.ignored. | D.relaxed. |
A.says bad words behind people. |
B.quarrels face to face with neighbors. |
C.bargains with salespeople over the price |
D.a(chǎn)sks about other people’s business |
A.Someone who often claps at the wrong time during a performance. |
B.Someone who feels ache in his neck due to a cold in the muscles. |
C.Someone who sits next to you smoking, which you never enjoy. |
D.Someone who keeps eating or talking all through the movies. |
A.To tell people what might be bad manners in public. |
B.To criticize (批評(píng)) the people who might be a “pain in the neck” |
C.To show anger to those who are described as a “pain in the neck”. |
D.To tell people how to stop the pain in the neck. |

Interactive Home-security Systems
Tarik Celebi, who lives in San Francisco suburb, takes his home-security system with him to work, to dinner, just about anywhere.By his cell phone, he "arms" his home-security alarm from his car before he leaves for work.During his workday, he gets e-mail alerts every time his front door opens, even though he's miles away.If the door opens at an unusual time -say midday when no one should be coming or going - he can order a 30-second video clip(片段) from the camera that watches the door.If it's just his mother-in-law getting a package delivery, no worries.
Celebi is one of the first users of the latest interactive home-security systems.In addition to sounding alarms when the house is broken into and notifying homeowners or police, as traditional systems do, the interactive systems give users new ways to remotely control their systems and their home environment.Different from traditional home-security alarms, which homeowners typically have to press buttons on a keypad to turn on before they leave their homes, the interactive systems enable consumers to arm and disarm systems from smart phones, iPads and PCs, no matter where they are.
Most traditional systems are set up to sound an alarm if doors or windows are opened. The interactive systems give homeowners more options.For example, users can elect when they want to be notified.They might want an e-mail or a text every time a door is opened, or only during the hours of 3 to 4 p.m., when kids come home from school.Like Celebi, they can add cameras and get video clips when doors open.That could be helpful in making sure kids aren't bringing friends home when they're not supposed to.
Nationwide, about 20% of homes have.traditional home-security systems.About half stop using them because they tire of the trouble.Being able to arm systems even while dashing to the subway or while at work will increase their usage of the new interactive systems.Although the new functions add costs to home security, the interactive-systems are believed to push home-security systems' usage rates closer to 30%, which would be a big movement for an industry that's been largely stuck at 20% for the past decade."We all know it's going to get bigger, though we don't know how long it's going to take," Eric Taylor, an officer from San Francisco Security Department says.
【小題1】What may Celebi first do if his front door opens at a wrong time when he is away?
A.Inform the police. | B.Call his mother-in-law. |
C.Arm the security alarm. | D.Observe through video. |
A.improve his home environment remotely |
B.lock his house's door while he is miles away |
C.operate the home-security systems at any place |
D.sound the alarm and inform the police at the same time |
A.They are cheaper. |
B.They are easier to set up. |
C.They can give quicker reaction. |
D.They have more ways to inform the users. |
A.The importance of security industry. |
B.The functions of the interactive alarms. |
C.The popularity of home-security systems. |

Make the most of college
Dear Daughter,
As we drove off from Columbia, I wanted to write a letter to you to tell you all that is on my mind.
First, I want to tell you how proud we are. Getting into Columbia is a real testament of what a great well-rounded student you are. You should be as proud of yourself as we are.
Your college years will be the most important of your life. It is in college that you will discover what learning is about. This will be the period where you go from teacher-taught to master-inspired, after which you must become self-learner. So do take each subject seriously, and even if what you learn isn’t critical for your life, the learning skills you acquire will be something you will cherish forever.
Follow your passion in college. Take courses you think you will enjoy. Don’t be trapped by what others think or say, but make up your own mind.
Most importantly, make friends and be happy. College friends are often the best in life. Pick a few friends and become really close to them – pick the ones who are genuine to you. Don’t worry about their hobbies, grades, looks or even personalities.
Start planning early – what would you like to do? Where would you like to live? What would you like to learn? I think your plan to study fashion is good, and you should decide where you want to be, and get onto the right courses.
Whether it is summer-planning, or coursework planning, or picking a major, or managing your time, you should take control of your life. I will always be there for you, but the time has come for you to be in the driver’s seat – this is your life, and you need to be in control. Being in control feels great. Try it, and you’ll love it!
College is the four years where you have:
The greatest amount of free time
the first chance to be independent
the most flexibility(靈活性) to change
the lowest risk for making mistakes
So please treasure your college years – make the best of your free time, become an independent thinker in control of your destiny, be bold to experiment, learn and grow through your successes and challenges.
May your years at Columbia be the happiest of your life, and may you blossom into just what you dream to be.
Love,
Dad (&Mom)

Picture a library without books? Well, I can’t. Ever since I was little I would go to the library and take out numerous books. From picture books to beginning chapter books to YA books, books have always been a part of my life. Unlike many people today, I don't own a Kindle or a Nook or any type of e-reader. I prefer the old-fashioned book. There is something about holding a book and being able to turn the pages that I find comforting. In today's 21st century, books may become obsolete. For me that's something I find scary.
I am a fan of the old TV science-fiction series Twilight Zone. One episode(一段情節(jié))is about a librarian who has become obsolete. Though this episode aired in 1961, the writer of the series, Rod Serling was exactly on point when it came to predicting the future.
In fact, in San Antonio, Texas the first-ever bookless library in the country opened. The library is full of iMacs, tablets and iPads which cost a huge $2. 3 million. The library offers around 10,000 e-books. So the question is, is this what the future will soon be? Mary Graham, vice president of South Carolina's Charleston Metro Chamber of Commerce states, "This is the future…If you're going to be building new library facilities, this is what you need to be doing."
It is our generation that will be the guinea pigs(試驗(yàn)品)of increasing technology like this. Is this a good or bad thing? Well, digital libraries may help the environment by not using paper; however, I feel like something will always be lacking with a digital book. A digital library is just the beginning.
With all of this new technology, people seem to be more absorbed in their own world. One of my biggest complaints is when I am with my friends and they can't seem to get off their smart phone and talk to me. To make plans with a friend and then have them stuck on their phone the whole time is extremely rude. Not only is it disrespectful, but it reflects the direction of where human interactions are heading. Though social media is great, it also is addicting and has negative effects.
Often when I go on Facebook it just makes me feel worse about myself. I'll see many of my 800 Facebook friends showing off their newest accomplishment or acceptance to college. Additionally, our society is becoming increasingly lazy. For instance, instead of doing mental math, people use their phone to solve 89 + 74. It is simple tasks like these that are allowing people to lack important educational and social skills.
It is up to us to find a balance between technology and human values and interactions. With new technology being created every day, we need to learn how to use it alongside our great minds. After all, inventions are supposed to benefit society not harm it. In the day of technology, who knows what's next?
【小題1】The underlined word "obsolete" (Paragraph l)is closest in meaning to .
A.outdated | B.complex | C.expensive | D.meaningless |
A.The episode still enjoys great popularity nowadays. |
B.Rod Serling liked making predictions about the future. |
C.The situation of books today is similar to what Rod Serling predicted in the episode. |
D.The episode airing in 1961 was the most entertaining of the TV science-fiction series. |
A.It is the first-ever library in America. |
B.It is of no practical use although it costs so much. |
C.It holds an exhibition of much electronic equipment. |
D.People can read e-books there with the help of the new facilities. |
A.Great as social media is, it does have some negative effects. |
B.With the increasing use of social media, something will actually be lost. |
C.Through social media, people can develop educational and social skills around. |
D.As a result of social media, people may communicate less with the people around. |
A.Optimistic | B.Skeptical | C.Supportive | D.Objective |
