Johann Gutenberg, who worked as a goldsmith (金匠), took what had already been discovered, and created a small invention that changed history. He created a machine that allowed him to move small blocks of letters in such a way that written material could be printed and mass-produced. Few people could read before Guttenberg made the invention, but once books became less expensive, more Europeans could read and write.
Block printing existed long before Gutenberg. The Chinese had been using wood blocks to print books as early as 868, but a new set of woodcuts (木刻印版) had to be made for each book. Producing one book was not easy; producing all kinds of books was more difficult.
Writing ink dates from about 2500 BC in Egypt and China. Gutenberg used an oil-based printing ink that would last longer than other inks used in his time. We don’t know much about Gutenberg because he was not famous during his lifetime. He was born in Germany about 1400. In 1448, Gutenberg developed signatures for each number, letter, and punctuation mark (标点符号). He then built the molds (模型) to hold the signatures in place. Gutenberg published the first mass-produced book: a 1,282 page Bible. To this day, more copies of the Bible have been printed than any other book.
Copies of Gutenberg’s invention spread throughout Europe, but the German goldsmith did not get rich from his invention. Some officials denounced the invention of printing because they feared that it would spread bad ideas. By 1500 there were 1,700 printing presses in Europe. The presses had already produced about 20 million volumes (册) of 40,000 different books.What happened after Johann Gutenberg’s invention?

If you are sitting down listening to what I’m going to say, stand up. Move your legs. Touch your toes, if you can. Do anything but sit.
If you cut down on the time you spend sitting, you might live longer. New research shows that sitting less than three hours a day might extend your life by two years.
Just the opposite, says Peter Katzmarzyk. He is a scientist at the University of Louisiana in the southern United States. He says that sitting is ubiquitous in our lives. "We sit while we're eating; we sit in the car; we sit while we watch TV. Many of us sit for many hours at work. " But, he adds, that does not make sitting good for us. The human body is designed to move. But modern lifestyles and office jobs rarely give us the chance to move around.
Exercise is important. So is not sitting.
"We can't throw away physical activity. It's extremely important. We have 60 years of research showing us that. Even if you exercise for 30 minutes a day, what goes on in the other 23-and-a-half hours a day is also very important."
Mr. Katzmarzyk and his co-workers are part of a new generation of researchers studying how sitting all day affects length of life. This is a relatively new area of study—studies that have assessed the relationship between sitting and mortality(死亡) or television viewing and mortality.
Making uses of the few studies available to them, they found that cutting television time to less than two hours a day could add one-point four years to life.
New desk designs are helping
Change is already coming to some offices, especially in the design of desks. A "standing desk" lets people stand while they work. Another new design is called the "treadmill desk." A treadmill is an exercise machine that lets you walk in one place. That's one of the strategies that many companies are using now. Some companies may equip their employees with a "standing desk" or a "treadmill desk". Other companies may not buy one for everybody, but they'll have a bank of these desks where people can go for an hour a day and answer their emails or talk on the phone. Even some U.S. schools are beginning to experiment with such desks to keep children moving.
Mr. Katzmarzyk says studying this problem has inspired his team to make a few changes in their own lives. "As a university professor, you know, it is a very sedentary occupation. We're chained to a desk in terms of writing papers and doing research. We really try to limit the amount of time we spend doing that."
Suggestions for sitting less
If you work in office job or have a sedentary job, Mr. Katzmarzyk and his team suggest a few simple changes:
get up from your desk as often as you can take walks at lunch time walk to your colleagues’ offices and talk directly instead of emailing them All these activities may help you live longer.What might be the best title for the passage?
| A．Take exercise, keep fit. |
| B．Change more, achieve greater. |
| C．Talk directly, improve relationship. |
| D．Sit less, live longer. |
The word “ubiquitous ” (in Para. 3) means “_______”.
| A．common | B．normal |
| C．individual | D．specific |
Mr Katzmarzyk holds the view that _______.
| A．the study doesn’t benefit him at all |
| B．it’s unnecessary to limit television time |
| C．emailing colleagues is better than a face-to-face talk |
| D．those taking exercises 30 minutes a day still can’t sit long |
The passage is most likely to be _______.
| A．a medical research | B．a book review |
| C．a health report | D．a sports feature |
The first day of school always goes wrong. For many students in the United States, however, this year it was even more so. It was all due to one extra school policy – they are now required to follow a new standardized dress code.
According to the handbooks of all high schools in Allentown, Pennsylvania, students must wear short- or long-sleeve polo shirts and khaki (卡其色) or black pants. Skinny jeans, leggings and open-toe shoes are not allowed.
Allentown schools are not alone. At Edgewater High School in Florida, shirts must have collars or sleeves, and pants must not sag (下垂) and reach at least mid-thigh (大腿中部). No see-through shirts or T- shirts with references to sex on them are allowed.
Overall, more than half of US public schools now enforce dress codes, according to the National Center for Education Statistics. About 57 percent of schools now have a “strict dress code”, up from more than 47 percent a decade earlier, USA Today said.
Among young people, there are mixed emotions. Some don’t mind wearing similar clothes every day while others aren’t happy. Despite dress codes in many school districts, some students still come to school – even on their first day – in skirts that are too short, necklines that are too low and sagging pants that don’t stay up on their hips.
But there are punishments. If they are out of dress code, students can be removed from the classroom until they fix the problem. In Florida, wearing sagging pants is illegal for youths according to a state law issued in 2011. Breaking the rule results in not being able to do after-school activities, and even being forbidden to attend class.
Some US schools go further and require students to wear uniforms. Many say that they simplify their jobs, saving teachers from having to punish students for wearing skirts or shorts that are too short, for instance. They can also prevent feelings of competition and envy among students.
“It takes away the daily fashion show and helps level the playing field a little bit with the haves and have-nots,” longtime school safety consultant Ken Trump told USA Today.
Critics of uniforms say they rob students of individuality. But for some people, that’s a lazy argument.
“Clothing isn’t the only form of self-expression. Students should know that it’s what they do that counts,” commented a parent named Beth Kassab in The Orlando Sentinel in Florida.According to the new standardized dress code, students in the US are allowed to wear.
| A．knee-length pants | B．shirts without sleeves |
| C．transparent T-shirts | D．jeans sticking to skin |
What is the main idea of Para 5?
| A．What the new dress code is. |
| B．How students dressed themselves. |
| C．What punishments students may receive. |
| D．How students responded to the code. |
Students in some US schools are required to wear uniforms Not to.
| A．pay less attention to their appearance |
| B．prevent comparison among students |
| C．bring out the best in students |
| D．spare teachers from punishing students for their improper dress |
What do Beth Kassab’s words imply?
| A．Uniforms limit the individuality of students. |
| B．Students should pay more attention to their behavior. |
| C．Clothing is of no importance to students. |
| D．Students should concentrate more on their study. |
Night after night, she came to tuck me in(掖好被子), even long after my childhood years. Following her longstanding custom, she'd lean down and push my long hair out of the way, then kiss my forehead.
I don't remember when it first started annoying me — her hands pushing my hair that way. But it did annoy me, for they felt work-worn and rough against my young skin. Finally, one night, I shouted at her: "Don't do that anymore — your hands are too rough!" She didn't say anything in reply. But never again did my mother close out my day with that familiar expression of her love. Lying awake long afterward, my words rang in my mind. But pride overwhelmed my conscience, and I didn't tell her I was sorry.
Time after time, with the passing years, my thoughts returned to that night. I missed my mother's hands, missed her goodnight kiss upon my forehead. Sometimes the incident seemed very close, sometimes far away. But always it appeared in the back of my mind.
Well, the years have passed, and I'm not a little girl any more. Mom is in her mid-seventies, and those hands I once thought to be so rough are still doing things for me and my family. She's been our doctor, reaching for medicine to calm a young girl's stomach or ease the pain of a boy's injured knee. She cooks the best fried chicken in the world…gets stains out of blue jeans like I never could…and still insists on dishing out ice cream at any hour of the day or night.
Through the years, my mother's hands have put in countless hours of toil, and most of hers were before automatic washers!
Now, my own children are grown and gone. Mom no longer has Dad, and on special occasions, I find myself drawn next door to spend the night with her. So it was that late on Thanksgiving Eve, as I drifted into sleep in the bedroom of my youth, a familiar hand hesitantly stole across my face to brush the hair from my forehead. Then a kiss, ever so gently, touched my brow.
In my memory, for the thousandth time, I recalled the night my surly young voice complained: “Don't do that any more —your hands are too rough!” Catching Mom's hand in hand, I blurted out how sorry I was for that night. I thought she'd remember, as I did. But Mom didn't know what I was talking about. She had forgotten —and forgiven —long ago.
That night, I fell asleep with a new appreciation for my gentle mother and her caring hands. And the guilt I had carried around for so long was nowhere to be found.Why was the author annoyed with her mother?

Eating at a slow speed may help reduce hunger, the U.S. researchers said on Monday. Previous research suggests that the ability to control energy intake may be affected by the speed at which we eat, and a high eating rate may damage the relationship between the sensory signals and processes that control how much we eat.
In order to learn more about the link between eating speed and energy intake, researchers examined how eating speed affects calories consumed during a meal in both normal-weight subjects as well as overweight or obese subjects.
In the new study, a group of normal-weight subjects and a group of overweight or obese subjects were asked to consume two meals in a controlled environment. All subjects ate one meal slowly, took small bites, chewed thoroughly, and paused and put the spoon down between bites, and are a second meal quickly, took large bites, chewed quickly, and did not pause and put the spoon down.
At the conclusion of the study, the researchers found only normal-weight subjects had a statistically significant reduction in caloric consumption by eating slowly. “A lack of statistical significance in the overweight and obese group may be partly due to the fact that they consumed less food during both eating conditions compared to the normal-weight subjects,” Professor Meena Shah said, “it is possible that the overweight and obese subjects felt more self-conscious, and thus ate less during the study.”
Despite the differences in caloric consumption between the normal-weight and overweight and obese subjects, the study found some similarities. Both groups felt less hungry later on after the slow meal than after the fast meal, which indicates that greater hunger suppression（抑制）among both groups could be expected from a meal consumed more slowly. Also, both the normal-weight and overweight or obese groups consumed more water during the slow meal. “The higher water intake during the slow eating condition may have affected food consumption,” said Shah. According to Shah, slowing the speed of eating may help suppress hunger levels and “may even improve the enjoyment of a meal”.
The findings were published in the Journal of the Academy of Nutrition and Dietetics.What does the previous study have in common with the new one?
| A．There is a link between eating speed and energy intake. |
| B．Eating at a slow speed may help feel hungry. |
| C．Eating too fast may impair your stomach. |
| D．Eating rate may affect processes controlling how much we eat. |
What should the subjects do during the research?
| A．Both groups could totally eat the meals at any speed as they liked. |
| B．Both groups had to consume one meal in controlled eating conditions. |
| C．Both groups were asked to eat one meal slowly while the other quickly. |
| D．One group should eat slowly while the other one quickly. |
What caused the lack of statistically significant reduction in the overweight and obese group?
| A．They were told not to eat a lot. |
| B．In the study they had no appetite to eat. |
| C．They lost consciousness in the study. |
| D．They ate less food on purpose. |
What is the passage mainly about?
| A．New research findings about how to control eating rate. |
| B．A study about the link between eating speed and energy intake. |
| C．One may feel less hungry later on after the slow meal than after the fast meal. |
| D．Water intake may have affected food consumption. |
“I say, I’m pleased to see you,” said the little man standing by the letter-box.
“Oh, hello,” I said, remembering he was a new neighbor. “Simpson, isn’t it?”
“Yes, that’s right.” He seemed quite pleased by my ready recognition.
“I wonder if you could lend me some money,” he continued. “My wife gave me a letter to post, and I’ve just noticed it isn’t stamped.”
“yes, they never are,” I said, sympathetically（同情地）.
“It must go tonight—it really must! I’d get stamps out of the machine,” explained Simpson,” Only I find I have no small change about me.”
“I’m sorry, but I’m afraid I haven’t either,” I said.
“Oh, dear, dear,” he said.
“Yes, well,” I said, intending to move off. But he looked so unhappy standing there with the blue unstamped envelope that I really hadn’t the heart to desert him.
So I took him to my house and found some pennies and gave them to him, who, in the most business like way, made a note of the loan in his pocket-book, and left. But soon he turned up again.
“I’m sorry I am a stranger round here and —well, I’m rather lost…”
It took me several minutes to explain to him where the post office was. In the end I felt as lost as Simpson and had to accompany him to the post office, but, only to find the automatic stamp-machine was empty!
“Oh!” Simpson was so desperate that he dropped the letter on the ground and when he picked it up there was a large black spot on its face.
“Dear me,” he said, “My wife told me to post it tonight. I’d better post it, if you know what I mean.”
I did know. Or, at least, I knew Mrs Simpson.
Then I got a good idea, “Post the letter unstamped—let the other man pay double postage on it in the morning. ” And he had to agree.
Finishing off our job, I took him home.
“I’m so grateful to you, really,” he said when we reached his home. “That letter—it’s only an invitation to dinner to Mr… Dear me!”
“Why, what’s the matter?”
“Nothing. Just something I’ve remembered.”
“What?”
But he didn’t tell me. He just opened his eyes and his mouth at me like a wounded gold- fish, murmured（低声说话）a “Good-night”, and went inside.
All the way home I was wondering what it was that he had remembered.
But I stopped wondering the next morning, when I had to pay the postman double postage for a blue envelope with a large black spot on its face.Simpson was very happy when the writer greeted him because ____.
| A．they were good friends |
| B．he had a very important letter to post |
| C．he saw somebody he could turn to at last |
| D．he didn’t expect the writer to recognize him instantly |
In the writer’s view, ____.
| A．the consequence would be very severe if Simpson didn’t obey his wife |
| B．wives never gave their husbands money to post a letter |
| C．it bothered him to lead Simpson to the post office |
| D．he was as foolish as Simpson |
What did Simpson suddenly remember when they got his home?
| A．His wife was waiting for him to return. |
| B．The letter was only an invitation to dinner. |
| C．The letter was just addressed to the writer. |
| D．It’s unfair for the other man to pay for the letter. |
How would the writer describe Simpson?
| A．Stupid and careless. | B．Careless but warm-hearted. |
| C．Optimistic and kind. | D．Cautious but stubborn. |
