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.

If You Make a Mistake, Don’t Worry!
Yeah, you’ll want to forget about them, but mistakes can be useful. Making a mistake doesn’t mean it’s the end of the world. In real life you have to grow and mature, and with that comes some growing pains.
You know you should have studied hard but you went out with some friends instead. You know you should have put the money into the bank for a rainy day instead of spending it on all kinds of things you didn’t need.
It’s the growing pains called mistakes that most people make when they are growing up. Face them. You are going to make them. Learn from them. All of the people you wish to copy, such as all the experts in your business field, have made mistakes. They’ll continue to make mistakes for all their successes.
One of the major differences between people like them and the vast majority（大多数）of others is that they don’t let their mistakes stop them. Instead, they use their mistakes as learning tools.
At the very least, when you make a mistake, you’ll know what not to do. And you can help others by warning them of the mistakes you’ve made. Don’t let mistakes stop you from doing anything. Learn from them, don’t hide in a closet. Facing up to your mistakes now and later will mature.
What mistakes are you making right now? Take a look at anything you might be doing wrong. Take a step back and evaluate your situation, then fix whatever needs to be corrected. Then move forward.
Always remember your mistakes to remind yourself of what not to do for the future.
63. Why does the writer say mistakes can be useful?
A. Because you can get some growing pains.
B. Because experts also make mistakes.
C. Because you can mature by facing and learning from mistakes.
D. Because next time you know that money shouldn’t be wasted.
64. Which statement is true according to the writer?
A. Before you make any mistake, you had better lock the closet in your room.
B. Keep your mistakes in mind in order not to make the same mistakes again in the future.
C. Don’t go out with some of your friends any more.
D. Forget your mistakes and move forward.
65. When we make any mistake next time, we should do the followings except _       __.
A. Think about the reason why we make the mistake.
B. Try to correct the mistake.
C. Tell others not to make the same mistake as you do.
D. Be careful not to do anything.
66. From the text, we can infer that __     ___.
A. facing mistakes, some people lose heart
B. mistakes can be useful
C. mistakes can be called growing pains
D. Put away money when it is rainy

B
“Can I see my baby?” asked the happy new mother. The bundle (婴儿包) was placed in her arms and when she moved the fold of cloth to look upon his tiny face, she gasped—the baby had been born without ears. Time, however, proved that the baby’s hearing was perfect except his appearance.
One day when he rushed home from school and threw himself into his mother’s arms, he cried out bitterly, “A boy, a big boy … called me—a f-…freak.” She sighed, knowing that his life was to be endless of heartbreaks.
He grew up, handsome for his misfortune. A favorite with his fellow students, he might have been class president, but for that. He developed a gift for literature and music.
The boy’s father had a talk with the family doctor. Could nothing be done? “I believe we could graft(移植) on a pair of outer ears, if they could be donated (捐献),” the doctor decided. So the search began for a person who would make such a sacrifice for a young man. Two years went by. Then, “You’re going to the hospital, son. Mother and I have someone who will donate the ears you need. But it’s a secret.” said the father.
The operation was a brilliant success. His talents blossomed into genius. School and college became a series of successes. Later he married and entered the diplomatic(外交) service. “But I must know!” he urged his father. “Who gave so much for me? I could never do enough for him.”
“I do not believe you could,” said the father, “but the agreement was that you are not to know … not yet.” The years kept the secret, but the day did come … one of the darkest days that ever pass through a son. He stood with his father over his mother’s casket(灵柩). Slowly and tenderly, the father stretched forth a hand and raised the thick, reddish-brown hair to let out the secret.
59.The story is mainly about _______.
A．how a boy had new ears through an operation
B．what a devoted parent privately did for the child
C．how a disabled boy turned into a useful person
D．why a donator made a sacrifice to a bright boy
60.From the first paragraph we know that the mother _______.
A．was determined to donate her ears to perfect her son
B．kept her husband unknown about the baby’s situation
C．felt shocked and disappointed to see her new baby
D．complained of her bad luck to have a disabled child
61.What can be inferred from the passage?
A．The agreement was between the donator and the family.
B．The boy was so popular that he was made class president.
C．Finally the boy came to know who the donator was.
D．The mother donated her ears to her son after she died.
62.What moral lesson can we draw from this reading?
A．Real love lies in what is done unknown rather than what is done known.
B．It is up to parents to help their children heart and soul.
C．True beauty lies only in the heart not in appearance.
D．It is a virtue for young generations to learn to be grateful.
