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 |
There are many ways to find a job. It can be as easy as walking into a neighborhood store to look at its announcement board. Local stores often have areas where people can put small signs telling what kind of service they need or can provide. Such services include caring for children or cleaning houses.
Or, job searchers can look in the newspaper. Local new
spapers have employment announcements placed by companies seeking workers.
Another popular tool for finding jobs is the Internet. For example, people in four hundred and fifty cities around the
world can use the Craigslist Web site to buy objects, meet people or find a job. Craigslist says that it receives two million new job listings each month.
Another useful way to find a job is through a college or university. For example, students at the University of Texas in Austin can go to the Career Exploration Center to get help in finding a job. Of course, looking for a job requires knowing what kind of work you want to do. For example, there is a book called “What Color is Your Parachute ?” by Richard Bolles. This book has been helping people choose a career since it was first published in nineteen seventy.
Some experts also help people find jobs. Susan W. Miller owns a company called California Career Services in Los Angeles. She says her company helps people find jobs by first helping them understand their strengths, goals and interests. Then she provides them with methods and resources to help them find the right job.What is the passage mainly about?

People smile at times. However, the meaning of a smile in different cultures may be different. Depending on different cultures, smiling can express joy and amusement, but it can also show embarrassment.
People in the United States smile a lot. Every one smiles at each other in order to show they are open and friendly. However，in China, smiling is not only an expression of happiness, but also a way to avoid being embarrassed. Chinese people like smiling when they are embarrassed in order to avoid embarrassment. Smiling is a kind of good will but not sneer（嘲笑）. For example: When a child falls off from a bike, the adults in China may smile, which is a kind of gentle encouragement and not a kind of impolite laugh.
When a person from the United States might blush（脸红）with embarrassment or become offensive(冒犯的), a Chinese might blush with smile. To avoid serious misunderstanding, people who engage in intercultural communication should be able to understand the meaning of smiling properly. We can use smile to express all of the following feelings except _________,
| A．joy and happiness | B．amusement | C．embarrassment | D．fear |

Knowing about yourself not only means finding out what you’re good at and what you like，but also means discovering what you’re not good at and what you don’t like．Both help you to see your aim in life．
Although most students would be unhappy if they failed a very difficult physics examination，they have in fact learned a lot about themselves．They know that they should not become engineers or physical scientists．So failing can help a student to live a happier life if he learns something from it．They may then decide on their aims and choose the work they like and are fit for．
It is impossible to decide whether you like something until you have tried it．If you decide to play the piano，you need to take more than one lesson before knowing whether you are really interested in it or able to do well．It is not enough if you want to be a great pianist．You also have to like the hard practice and long training．If you enjoy being a great pianist but hate the work，forget it．
It’s a good plan to try as many ideas as possible when you are young．Then you will find out what your true interests are．If you say you really know yourself，．
