New research shows that the healthy brain may hold memories which we don’t even remember. In The Journal of Neuroscience, experts report that the brain might hold more memories than people realize, but that restoring those memories can be tricky.
Memory Check
First, participants saw a list of 120 real words mixed with 80 nonsense words. Next, they saw another word list and tried to remember which words had been on the first list. Meanwhile, their brains were scanned with functional magnetic resonance(核磁共振) imaging.
While participants reviewed the second word list, their brain scans showed more activity in a certain brain area -- the posterior（后部的） median temporal lobe(脑叶) -- when they saw words that had been on the first word list.
But participants didn’t always remember that they’d seen those words before. Sometimes, they goofed and said they hadn’t seen those words before. In other words, the posterior median temporal lobe was more sensitive to memory than participants’ consciousness, the researchers note.
“Album”of Memories
Another part of the median temporal lobe also attracted the scientists’ attention. The anterior（前面的）median temporal lobe showed more activity when participants thought they were seeing a new word, the study shows.
So, why did participants sometimes mess up their memory recall? It might be that two parts of their brain -- the posterior and anterior median temporal lobes -- might be dueling(决斗) for the upper hand in deciding what actually happened in the past, the study notes.
In other words, memories might have a photo album in the brain, but sometimes we forget what’s on all of the photo album’s pages.A person sometimes has difficulty recalling because .
| A．he is unconscious when he gets his memories |
| B．he forgets what is on the pages of the photo album |
| C．there are two parts in his brain dueling for the upper advantage |
| D．the anterior median temporal lobe is more active than the posterior |
According to the passage the researchers are .
| A．studying how a person remembers things |
| B．studying a magazine The Journal of Neuroscience |
| C．examining posterior and anterior median temporal lobes |
| D．doing experiments to find out what disturbs a person’s memory |
What did the experts discover when the participants saw the words on the first word list appear on the second word list?
| A．The instrument worked faster. |
| B．The participants were more conscious. |
| C．The posterior median temporal lobe was more active. |
| D．The anterior median temporal lobe was more active. |
The underlined wordgoofedin the fourth paragraph means .
| A．made a mess of | B．made an answer for |
| C．made out of | D．made the best of |
Do you sometimes argue about what seems to you to be a simple fact? Do you argue whether it’s cold outdoors or whether the car in front of you is going faster than the speed limit?
If you get into such arguments, try to think about the story about the six blind men and the elephant. The first blind man who felt the elephant’s trunk said it was like a snake. The second who felt the elephant’s side said it was like a wall, while the third said it was like a spear as he touched the animal’s tusk. The fourth, who took hold of the elephant’s tail insisted that it was like a rope. The fifth man said it looked like a tree as he put his arms around one of the elephant’s legs. The sixth, who was tall and got hold of theelephant’s ears, said it was like a huge fan.
Each man’s idea of the animal came from his own experience. So if someone disagrees with you about a “simple fact”, it’s often because his experience in the matter is different from yours.
To see how hard it is for even one person to make up his mind about a “simple fact”, try this simple experiment. Get three large bowls. Put ice water in one. Put hot water in the second. Put lukewarm water in the third. Now put your left hand in the ice water. Put your right hand in the hot water. After thirty seconds, put both hands in the lukewarm water. Your right hand will tell you the water is cold. Your left hand will tell you it’s hot.What makes people think about simple facts differently?
| A．The fact that simple facts differ from one another. |
| B．The fact that people have different experience in the same simple fact. |
| C．The fact that people often disagree with one another. |
| D．The fact that it’s hard to make up one’s mind about simple facts. |
The writer’s advice is that ________.
| A．we should never think about simple facts |
| B．we should never judge something with a one-sided view |
| C．we should not agree about simple facts |
| D．we must learn from the six blind men |
What’s the main idea of this passage?
| A．People often judge something according to their own experience. |
| B．People often agree about simple facts. |
| C．It’s hard for a person to make up his mind about a simple fact. |
| D．Don’t care too much about simple facts. |
Education is not an end, but a means to an end. In other words, we do not educate children only for the purpose of educating them. Our purpose is to fit them for life.
In some modern countries it has for some time been fashionable to think that by free education for all-whether rich or poor, clever or stupid-one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degrees refuse to do what they think to be "low" work, and, in fact, work with hands is thought to be dirty and shameful in such countries. But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a profess-or, we can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases in our towns.
In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in such a way that, firstly, each of us can do whatever work suited to his brains and ability and, secondly, that we can realize that all jobs are necessary to society, and that is very bad to be ashamed of one's work. Only such a type of education can be considered valuable to society.From the passage we can conclude that______.
| A．education can settle all of the world's problems |
| B．free education for all probably leads to a perfect world |
| C．free education won't help to solve social problems |
| D．all the social problems can't be solved by education |
The writer wants to prove that _____.
| A．our society needs all kinds of jobs |
| B．our society needs free education for all |
| C．a farmer is more important than a professor |
| D．people with university degrees refuse to do what they think to be "low" work |
According to the passage _____.
| A．work with hands is dirty and shameful |
| B．work with hands is low work |
| C．work with hands is the most important |
| D．we can't regard work with hands as low work |
The purpose of education is _____.
| A．to choose a system of education |
| B．to prepare children mainly for their future work |
| C．to let everyone receive education fit for him |
| D．to build a perfect world |
The passage tells us about _____.
system of education
B. means of education
C. value of education
D. type of education
We often find that weekends and holidays feel so short while classes and work feel so long. In reality, though, we know that this is not true. But we still wonder where that strange feeling comes from.
In fact, this is one of the ways that we're tricked by time, according to the website All That Is Interesting. The website lists several wrong impressions we often have about time. Let's have a look.
First of all, emotions affect our time-keeping abilities: Negative emotions, especially anxiety and boredom, make time seem longer because they make us concentrate more on the passage of time. However, when we are enjoying ourselves, we pay more attention to what we are doing and are likely to lose track of(失去对…的意识) time.
Here is another example. In 2007, a group of scientists carried out a test. In the test, people fell 50 meters into a safety net and were then asked about their experience. Although the experience took shorter than 3 seconds, the people thought it was much longer than it actually was.
This is because of the way our bodies reply to danger, according to the scientists. Our bodies produce a chemical called adrenaline(肾上腺素) when we are faced with danger. It allows us to concentrate better so that we can stay alive. As a result, we are able to remember far more details over a short period of time, which makes it seem like time is going more slowly.
Another occasion when we make mistakes about time is when we take afternoon naps(午觉). Have you ever had trouble telling what time it is after a long nap? That's because the best amount of time for a nap is 20 minutes. After 20 minutes, you enter a new stage of sleep called slow-wave sleep. If you wake up mid-way in this stage, it will take a while before you can correctly perceive(感知) time again.
Yes, time can be mysterious and there is no way to control it So, perhaps the best thing to do is to make good use of every minute. How many examples of being tricked by time are mentioned in the article?
| A．Two | B．Three | C．Four | D．Five |
When people feel that an experience is longer than it really is, _________.
| A．a chemical called adrenaline is playing a role |
| B．they are concentrating on what they are doing |
| C．they are responding faster to the changes around them |
| D．they could be facing danger or feeling bored |
According to the passage, in which situation do we make mistakes about time?
| A．We have a math test when we fall down from a high place. |
| B．We have trouble telling what time it is after a 20 minutes’ nap. |
| C．We have many problems left in the test paper, but the time is up. |
| D．We go to school on the school bus as usual on weekdays. |
What is the article mainly about?
| A．How emotions affect time keeping abilities. |
| B．Tests which scientists carried out about time. |
| C．The best amount of time for an afternoon nap. |
| D．Mistakes that people make in their understandings of time. |

The Hunan Satellite TV(HNTV) show “Where are we going, Dad?” is a big hit. Many famous stars brought their children to a strange village alone, and they had to spend 72 hours with their children there. The program fully showed us a modern version of the “how to be a good father”. As the young parents today are too busy to take care of their children, this new form of “Lost on the way” played by nanny Daddy and cute kids triggered（触发）a lot of people’s emotional resonance（共鸣）. Both the kids and their parents will find that their hearts are being drawn closer. But this kind of feeling has just proved that there is a big spiritual barrier between the modern parents and children.
The TV shows like “Children are hard to support!”, “Where are we going, Dad?”, “hot mom” and “cute kids” are becoming more and more popular. All of these show the new parents’ confusion in children’s education and the appeal for the balance between career and family.
In real life, on the one hand the young parents feel helpless because they are too busy to accompany their children under the pressures of work and life; on the other hand they continue to do so. The data collected by HNTV shows that nearly two-thirds of their audience are female, among whom 36% are aged from 25 to 34.We can imagine such a scene that one evening a young mother is watching the show with her young children, while her husband is still at work or trapped in socializing, or maybe is just playing computer games in the bedroom. The story of a child without the company of father is still going on. In fact, it is sometimes the same to mothers. In a modern family, it is often the old who take the responsibility of raising a child. The participation of mother in the children’s education is also very low.
It is just this kind of confusion where the parents have gone in the modern family education, and where the parents will guide their children to go that “Where are we going，Dad?” shows us. If a child wants to grow up healthily and safely into a modern citizen with independent personality and free spirit, it is very important for him or her to follow the parents who serve as their first teacher. Maybe this is the real reason why such kind of TV programs could get hot. The truth is that children will go where their parents go; and society will go where the children go. In raising a child in modern society, parents should ________.
| A．play computer games with their children |
| B．keep their children at home to avoid socializing |
| C．balance well between family and career |
| D．break down the barrier between children and teachers |
Which of the following can be inferred in the passage?
| A．Parents shouldn’t entirely leave the education of children to the old. |
| B．36% of the audience of the program are female aged from 25-34. |
| C．The program shows us the confusion where the parents and children will go to play. |
| D．In a modern family it is often mothers who are responsible for raising a child. |
Which one is the best title of the passage?
| A．Confusion Behind “Where are we going, dad?” |
| B．Modern Education is Important |
| C．Nanny Daddy and Cute Kids |
| D．New problems in Modern Children’s Education |
What attitude towards modern family education does the author express in the second paragraph?
| A．Proud. | B．Worried. |
| C．Optimistic. | D．Indifferent. |
