Some wonderfully creative uses of X-rays have been in the world of art.But the most impressive one is to uncover what has been covered up.Details unfolded by an X-ray of a painting can ' t be seen any other way.For example, in the past, paintings were often repaired if small pieces of paint fell off the canvas (帆布). These repairs cannot be seen just by looking at the painting.It takes an X-ray to discover where the repairs have been made.
An X-ray of a painting is one of the best ways to tell if it was created by a famous painter or if it is a forgery(贗品).If there is a question as to whether an old master has painted a certain painting or not, X-rays are made and compared to those of paintings that are known to be original.If the brushstrokes (筆跡) , for example, are shown to be totally different than in other work done by a certain artist, then the painting is proved to be a fake copy.
Since modern paints are usually made from different materials than paints of hundreds of years ago, the image they leave on an X-ray film looks different.This is another way X-rays can be used to spot a forgery.A modem artist will try to make a forgery look hundreds of years old by painting dirty varnish on it or by using artificial means to get the varnish to look cracked.To the naked eye the forgery may look old, but when a careful study of the X-ray image is made, the deception is obvious.
It was common many years ago for an artist to finish a painting, decide it wasn't any good, and paint a completely different picture on top of it.Or artists would paint over others' work —it was their version of recycling.Taking an X-ray is the only way to find out if there is a picture underneath the picture you see with your eyes.Sometimes museums will be more interested in the painting beneath than the one on top, and will restore the older one by having the top layer painstakingly removed.

Some people have very good memory(記憶力) and they can easily remember quite long texts. There are other people who can only remember things when they have said them again and again. The famous English writer Charles Dickens said that he could walk down any long street in London and then tell you the name of every shop he had passed. Many great men of the world have a wonderful memory.
A good memory is greatly helpful in learning a language. Everybody learns his own language by remembering what he hears when he is a small child, and some children, like the boys and girls who live abroad(國(guó)外) with their parents, seem to learn two languages almost as easily as one. In school it is not so easy to learn a second language because the students have so little time for it, and they are very busy with other subjects too.
A man’s mind is like a camera, but it takes photos not only of what we see but also of what we feel, hear, smell and taste. When we take a real photo with a camera, Some people have very good memory(記憶力) and they can easily remember quite long texts.In the same way, there is much work to be done before we can keep a picture forever(永遠(yuǎn)) in our minds.
Memory is a diary, and we all carry it about us. We keep things we have experienced (經(jīng)歷)in this diary.
小題1:Which of the following is true?
A.Charles Dickens had a good memory because he was a famous writer.
B.People without a good memory cannot be great men of the world.

Going to school from 8 am until 5 pm may sound terrible,but Sydney Shaw,a seventh grader at the Alain Locke Charter Academy on Chicago's West Side,has come to like it—as well as the extra 20 or so days that she's in class every year.“I'm sure every kid at this school says bad things about the schedule sometimes,”says Sydney, who was at school on Columbus Day, when most Chicago schools had a holiday.“But we all know it's for our benefit.”
Finding ways to give kids more classroom time,through longer hours,a longer school year,or both,is getting more attention.“If you want to look at schools where the achievement gap is narrowing, they're saying they couldn't do it without the added time,”says Jennifer Davis.“Even when you get good teachers into schools,you also need more time.”
According to studies, low-income students fall back more than two months in their reading skills over summer vacations.“It's over the summer months that poor kids fall behind,”says Karl Alexander,a sociologist.“If you have parents who themselves didn't succeed at school and aren't highly educated,kids aren't going to get those skills at home.”
Schools are asked to take a full year to plan how to best use the extra time—a process involving teachers,principals,students and parents.They are given outside support to help them base their plans on the best available analyses of student needs.It's still early,but officials are already seeing stronger test scores and a narrowing achievement gap.
But some critics are worried.“We risk producing something that's very expensive and time-consuming, and that will give educators a lot of trouble,”says Frederick Hess.“Before we spend all that extra money,I'd much rather see if we can figure out how to get 50 percent more instructional time out of the current school day.”
小題1:From the first paragraph,we learn that      
A.the longer schedule is harmful to kid's health
B.a(chǎn)ll Chicago students had a holiday on Columbus Day
C.Sydney Shaw supports the added time
D.few kids are bored with the lack of holidays
小題2:Low-income students fall behind in summer because      
A.no good teachers are willing to teach them
B.they can't get help from their parents
C.their parents are unwilling to hire private teachers
D.they themselves have no desire to learn
小題3:Some people are worried about adding school hours mainly because      
A.it will have a bad effect on the kids’ futures
B.the current school day has been too busy
C.no one supports the idea
D.it will be costly and time-consuming
小題4:The text is mainly about      
A.whether a longer school day will help narrow the achievement gap

We lived in a very quiet neighborhood. One evening I heard a loud crash in the street. Earlier that evening my wife had asked me to go to the store to get some soft drinks. It seemed like this would be a good time to let my teenage daughter Holly practice her driving, so I sent her to the store in my truck.
At dinner my son talked about how much he liked my truck. I enjoyed having it, but I said: "Guy, my heart is not set on that truck. I like it but it is just metal and won’t last forever. Never set your heart on anything that won’t last."
After hearing the loud noise, the whole family ran outside. My son shouted: "Dad! Dad, Holly crashed your truck."
My heart sank and my mind was flooded with conflicting thoughts. Was anyone hurt? Who else was involved? As I ran to the door, I heard a voice in my heart say: "Here is a chance to show Holly what you really love. She’ll never forget it."
The accident had occurred in my own driveway. Holly had crashed my truck into our other vehicle, the family van (搬運(yùn)車(chē)). In her inexperience, she had confused the brakes and the gas pedal. Holly was unhurt physically, but when I reached her, she was crying and saying: "Oh, Dad, I’m sorry. I know how much you love this truck." I held her in my arms as she cried.
Later that week a friend stopped by and asked what had happened to my truck. I told her the whole story. Her eyes moistened (濕潤(rùn)) and she said: "That happened to me when I was a girl. I borrowed my dad’s car and ran into a log that had fallen across the road. I ruined the car. When I got home my Dad knocked me to the ground and began to kick me."
Over 40 years later, she still felt the pain of that night.
I remember how sad Holly was and how I comforted her. One day, when Holly thinks back on her life, I want her to know what really matters in my life.
小題1:How did the crash happen?
A.The van was parked in the wrong place that evening.
B.Holly stepped on the gas pedal instead of the brakes.
C.The brakes of the truck didn’t work properly.
D.Holly was too careless and young to drive a truck.
小題2:Why didn’t the writer punish Holly?
A.He was so rich that he didn’t care about losing one truck.
B.He thought there was no point punishing her after the accident.
C.He believed the truck was made of metal and of poor quality.
D.He wanted Holly to know he loved her more than any possessions.
小題3:What does the underlined sentence mean?
A.She still suffered physical pain.
B.She felt guilty of damaging the car.
C.It left a deep wound on her soul.
D.She was not forgiven by her Dad.
小題4:Which of the following would be the best title for the passage?
A.What really matters?
B.Better to forgive and forget
C.Who is to blame?

Sometimes educators need to be reminded that their job is important and they are very much appreciated. Here are some movies that inspire us and make educators feel proud to be in the field of education where they really do have an impact.
The Miracle Worker
The ultimate teaching miracle, Anne Bancroft is awesome as Annie Sullivan who uses ‘tough love' to get through to the deaf and blind Helen Keller played by Patty Duke. Very few people can watch the famous ‘water' scene without experiencing a feeling of victory and relief. Excellent portrayal of the importance of perseverance. Both Bancroft and Duke won an Academy Award for their performances.
The Karate Kid
While not normally thought of as a ‘classroom' movie, The Karate Kid has much to say to teachers: Sometimes we have to have our students do things that they will not understand until much later; Basic skills are most important; Honor and integrity are central to character; Students need to see us beam with excitement over their achievements. A fun, nostalgic and inspiring movie to relish.
To Sir With Love
Produced in 1967, this film with Sidney Poitier as a novice teacher has a lot to teach us today. Poitier takes a teaching position in the rough part of London in order to pay his bills. Realizing that his students need to be taught important life lessons more than the curriculum he has been handed to teach them, he throws out the lesson plans and makes a real impact on their personal lives.
Mr. Holland's Opus
This memorable movie gives all teachers hope that they truly have an impact on their students. Richard Dreyfuss is wonderful as a musician/composer who must take a teaching job to support his family. In the end, Dreyfuss' character realizes that he has had as much if not more of an impact from his teaching ashe would have as a composer.
小題1:The four films above are specially intended for_______.

It's not just adults who have a thing or two to discuss with other people, babies too have their own social lives and enjoy group interaction, according to a world-first study.
The breakthrough study conducted by psychologist Professor Ben Bradley, at Charles Sturt University, could completely transform the way child-care centers are set up. In their study, the researchers examined groups of nine-month-old babies in new South Wales and Britain.
And they came across astonishing results—it was found that infants had “social brains” and focused not just on their mothers but on social 1ife in groups as well,
“They communicate with more than one baby at once,and show jealousy and generousness,”said Professor Bradley.
He added,“They develop their own meanings through group interaction,they notice if a group member is behaving differently and they take on roles,such as leaders and followers.”
“A baby who has a depressed mother tends to be withdrawn(內(nèi)向的),but put that same baby in a group of its peers(同齡人)and they behave and interact like any other baby.”
It was the first all-baby group study ever to be conducted.“Most studies of babies concentrate on the infant-mother relationship,assuming that is the single foundation for mental health.but babies are constantly involved with groups of people other than their mothers:fathers,siblings,grandparents and those taking care.Therefore。the ‘mother-baby approach’ needs to be combined with a‘ group approach’.”said Bradley.
Phoebe Christison ,a child-care worker at Camperdown Sunshine Bubs in Sydney’s inner west.said she often noticed what appeared.to be emotional attachments developed between toddlers
She said,“Joel(10 months)and Isabella (11months)always like to hold hands when they sit in their high chairs and eat.And babies definitely show jealousy.They push and touch each other,and copy what the other is doing.”
小題1:A baby who has a depressed mother ____  .
A.tends to be a follower
B.a(chǎn)lso enjoys group interaction
C.has poor social ability
D.pays more attention to its mother
小題2:What can be inferred from the result of this study?
A.Babies are affected by groups more than by their mothers.
B.There’s no need of child-care centers at a11.
C. Adults should include babies when having social activities.
D.The normal infant-mother bond alone isn’t enough for the good mental health for babies.
小題3:The underlined word “toddlers” in Para.8 can be replaced by_________
A.a(chǎn)dultsB.infantsC.peersD.groups
小題4:The example given in the last paragraph proves that a baby________ .
A.is born to be friendly to other babies
B.has interest in peers as well as in its mother
C.may have emotional attachments to another baby
D.shows jealousy and generousness as an adult

Most of us seem to reach our peak of alertness (警覺(jué)) around noon. Soon after that, alertness declines, and sleepiness may set in by mid-afternoon.
Your short-term memory is best during the morning—in fact, about 15 percent more efficient than at any other time of day. So, students, take notice: when you are faced with a morning exam, it really does pay to review your notes right before the test is given.
However, long-term memory is different. Afternoon is the best time for learning materials that you want to recall days, weeks or months later. Politicians, business executives or others who must learn speeches would be smart to do their memorizing during that time of day. You should try to do most of your studying in the afternoon, rather than late at night. Many students believe they memorize better while burning the midnight oil because their short-term recall is better during the early hours of the morning than in the afternoon. But short-term memory won’t help them much several days later, when they face the exam.
By contrast, we tend to do best on tasks related to the process of knowing, understanding, and learning numbers during the morning hours.
What about sports? During afternoon and early evening, you’re able to react the quickest to an outside stimulus—like a baseball speeding toward you. Studies have also shown that late in the day, when your body temperature is peaking, you will consider PE easier and less tiring—whether it actually is or not. That means you are more likely to work harder during a late afternoon or early evening workout, and therefore benefit more from it.  
In fact, all of your senses—taste, sight, hearing, touch and smell—may be at their keenest during late afternoon and early evening. That could be why dinner usually tastes better to us than breakfast.
While all of us follow the same general pattern of ups and downs, the exact timing varies from person to person. It all depends on how your “biological” day is structured. Each of us can increase our knowledge about our individual rhythms. Learn how to listen to the inner beats of your body; let them set the pace of your day. You will live a healthier and happier life.
小題1:What does the underlined “it really does pay” mean?
A.It will cost a lot.B.It requires price.
C.It is very painful. D.It is worthwhile.
小題2:If there is an English exam two weeks later, you should go over English ____________ for days before that.
A.in the afternoonB.in the late evening
C.in the early morningD.right before the exam
小題3:From the passage, it can be inferred that ______________.
A.we eat more food at noon
B.we feel most tired if we exercise in the evening
C.it is a good choice to study math in the morning
D.we feel most sleepy before noon
小題4:Which would be the best title for the passage?

Steve, a twelve-year-old boy with alcoholic parents, was about to be lost forever, by the U.S. education system. Remarkably, he could read, yet, in spite of his reading skills, Steve was failing. He had been failing since first grade, as he was passed on from grade to grade. Steve was a big boy, looking more like a teenager than a twelve year old, yet, Steve went unnoticed... until Miss White.
Miss White was a smiling, young, beautiful redhead, and Steve was in love! For the first time in his young life, he couldn’t take his eyes off his teacher; yet, still he failed. He never did his homework, and he was always in trouble with Miss White. His heart would break under her sharp words, and when he was punished for failing to turn in his homework, he felt just miserable! Still, he did not study.
In the middle of the first semester of school, the entire seventh grade was tested for basic skills. Steve hurried through his tests, and continued to dream of other things, as the day wore on. His heart was not in school, but in the woods, where he often escaped alone, trying to shut out the sights, sounds and smells of his alcoholic home. No one checked on him to see if he was safe. No one knew he was gone, because no one was sober(清醒的) enough to care. Oddly, Steve never missed a day of school.
One day, Miss White’s impatient voice broke into his daydreams. “Steve!!” Startled, he turned to look at her.
“Pay attention!”
Steve locked his gaze on Miss White with adolescent adoration (青春期的愛(ài)慕), as she began to go over the test results for the seventh grade.
“You all did pretty well,” she told the class, “except for one boy, and it breaks my heart to tell you this, but...” She hesitated, pinning Steve to his seat with a sharp stare, her eyes searching his face.
“...The smartest boy in the seventh grade is failing my class!”
She just stared at Steve, as the class spun around for a good look. Steve dropped his eyes and carefully examined his fingertips.
 After that, it was war!! Steve still wouldn’t do his homework. Even as the punishments became more severe, he remained stubborn.
“Just try it! ONE WEEK!” He was unmoved.
“You’re smart enough! You’ll see a change!” Nothing fazed him.
“Give yourself a chance! Don’t give up on your life!” Nothing.
“Steve! Please! I care about you!”
Wow! Suddenly, Steve got it!! Someone cared about him? Someone, totally unattainable and perfect, CARED ABOUT HIM??!!
Steve went home from school, thoughtful, that afternoon. Walking into the house, he took one look around. Both parents were passed out, in various stages of undress, and the stench(惡臭) was overpowering! He, quickly, gathered up his camping gear, a jar of peanut butter, a loaf of bread, a bottle of water, and this time...his schoolbooks. Grim faced and determined, he headed for the woods.
The following Monday he arrived at school on time, and he waited for Miss White to enter the classroom. She walked in, all sparkle and smiles! God, she was beautiful! He yearned for her smile to turn on him. It did not.
Miss White, immediately, gave a quiz on the weekend homework. Steve hurried through the test, and was the first to hand in his paper. With a look of surprise, Miss White took his paper. Obviously puzzled, she began to look it over. Steve walked back to his desk, his heart pounding within his chest. As he sat down, he couldn’t resist another look at the lovely woman.
Miss White’s face was in total shock! She glanced up at Steve, then down, then up. Suddenly, her face broke into a radiant smile. The smartest boy in the seventh grade had just passed his first test!
From that moment nothing was the same for Steve. Life at home remained the same, but life still changed. He discovered that not only could he learn, but he was good at it!
He discovered that he could understand and retain knowledge, and that he could translate the things he learned into his own life. Steve began to excel! And he continued this course throughout his school life.
After high-school Steve enlisted in the Navy, and he had a successful military career. During that time, he met the love of his life, he raised a family, and he graduated from college Magna Cum Laude. During his Naval career, he inspired many young people, who without him, might not have believed in themselves. Steve began a second career after the Navy, and he continues to inspire others, as an adjunct professor(副教授) in a nearby college。
Miss White left a great legacy. She saved one boy who has changed many lives. I know, because I am the love of his life.
You see, it’s simple, really. A change took place within the heart of one boy, all because of one teacher, who cared.
小題1:What does the underlined sentence in the first paragraph mean?
A.Steve would give up schooling forever.
B.Steve was at a loss about improving his study.
C.Being unhappy both in school and at home, Steve intended to end his own life.
D.Due to his poor study, Steve was about to be expelled from his school.
小題2:What made Steve change greatly all of a sudden?
A.Miss White’s encouragementB.Miss White’s praise
C.knowing Miss White concerned himD.Miss White’s persuasion
小題3:What might be the best title for this passage?
