High Speed Book Scanner
Simply turning pages of a book quickly may not seem like the best way to scan it. A Japanese research group at Tokyo University has created new software that allows hundreds of pages to be scanned within minutes. Scanning text is normally a boring process with each page having to be inserted into a scanner, but the team led by Professor Masatoshi Ishikawa uses a high speed camera that takes 500 pictures a second to scan pages as they are turned by workers.
Normal scanners can only scan the information that is actually before them on the page. This high speed book scanner uses a camera that captures pages at 1000fps as they are turned. A system built in allows it to automatically correct any changes to the text due to the page bending as well as light differences due to shadows. “It takes a shot of the shape, then it calculates the shape and uses those calculations to film the scanning,” Ishikawa said, explaining the system used to reconstruct the original page.
The current system is able to scan an average 250-page book in a little over 60 seconds using basic computer hardware. While it now requires extra time to process the scanned images (影像), the researchers hope to eventually make the technology both faster and much smaller. “In the more distant future, once it becomes possible to put all of this processing on one chip (芯片) and then put that in an iPad or iPod, one could scan just using that chip. At that point, it becomes possible to scan something quickly to save for later reading,” Ishikawa said.
Being able to scan books with an iPhone may be further off, but Ishikawa says that a commercial version of the large-scale computer based scanning system could be available in two or three years. While the technology has the potential to take paper books into the digital age, it remains to be how publishers will react to people scanning their books while just turning pages quickly.

When I was going home to India last year, I called up my mother to ask if she wanted anything from china,
When India had not opened up its markers to the world, I carried suitcase loads of dark glasses and jeans. Thankfully, we can get all these anywhere in India now,
Still ,her answer surprised me: “Green tea,”
As long as I can remember she didn’t even drink Indian tea.
I dutifully bought a big packet of Longjing and headed home to hear the story. My mother and her brother, both regular newspaper readers, believed that Chinese green tea was the wonder drug for all illnesses

But it’s a two-way street, I just heard about a thousand Shenzhen office workers who have gone to Rangalore to train in software. Meanwhile, all the IT majors are setting up a strong presence in China,
No wonder that trade, which was only in the millions just ten years ago, is expected to his about us$15 billion for last year and us$20 billion by 2008, a goal set by both governments,
No wonder, my colleague wrote some weeks ago about this being the Sino-Indian(中印)century as the two countries started on January I the Sino-Indian Friendship Year,

If you thought sports stars Yao Ming
and Liu Xiang or Internet entrepreneurs Zhang Chaoyang and Ding Lei would automatically be on the list of the” Men of Our Time”,then you could be behind the times.
The surprise in the list of 10 men released by the All-China Women’s Federation yesterday is that it contains no celebrities- and the guiding factors seem to be care and sympathy for the opposite sex.
In fact,Liu and Yao,as well as actor Pu Cunxin—the image ambassador for China’s anti-HIV,AIDS campaign—appeared in a booklet given out at the contest’s launch ceremony in January.The federation wouldn’t say why they are not in the final list.
The winners,with an average age of 47.5,were selected by women officials and journalists of the nine women’s newspapers in China,whose standard was men promoting equality between the sexes.
Li Zhong hua, a 46-year—old air force officer who test-flies planes,said he thought he was chosen because” he takes good care of his family,and is a gentleman”.
”Gentlemen get more respect in our society.They should be like those in the movie Titanic,who let women and children lave first in life rafts。”he told China Daily.
Shi Hua shan,a 48-year-old policeman in Gui xi of Jiangxi Province,said that he became a”man in the eyes of women” because” women love stories of heroes saving beauties".
His team has re
scued more than 180 women who were taken away by force and sold as wives in the mountain regions of Fujian Province.
Some other” Men of Our Time” are:
Lang Jinghe,67,gynecologist at the Peking Union Medical College Hospital in Beijing,who has made breakthroughs in ovarian cancer;
Ma Li,33,official in Xuzhou of Jiangsu Province,whose shelter has helped 196 victims of domestic violence;Li Mingshull,43,lawyer in Beijing,who is active in campaigns against family violence;Liu Ri,51,a mine worker in Lu’an of Shanxi Province,who took care of his paralyzed
parents·in-law for 23 years with his wife.

Televisions, stereos, telephones, and computers have changed the way we spend our time and what we know about the world. Some of the changes brought about by these material possessions have improved our way of life, but others have made it worse. Our young teenagers turn on the television, play the stereo, play games on the computer, talk on the telephone, and eat all the same time. This drives me right up the wall to instant insanity(精神失常).
However, teens of today place too great an importance on material property. They spend an average of several hours a day watching television, listening to stereos, playing on the computer, playing video games, and talking on the telephone. Families no longer watch television together and there is great lack of communication. Materialism is evident when an otherwise intelligent teenager drives their parents crazy, and into debt, when misusing communication equipment. Teens judge and admire other teens for what they own and have, rather than for what they are or what they can do. They no longer care about values, like honesty, integrity(正直), freedom, talent, quality and other values and morals.
However, good or bad, communication devices are here to stay. It is up to us, as parents, to stop our beloved teenagers from misusing and abusing our communication equipment and devices. We need to avoid the problems they present and to make the most of their opportunities they possess and hold for us all.
【小题1】The writer’s attitude toward the modern material possessions is generally _____.
| A.positive | B.negative | C.neutral | D.indifferent |
| A.their own health | B.their own study |
| C.their own morality | D.their neighbors’ life |
| A.teens’ too much free time | B.parents’ non-interference |
| C.inadequate school education | D.material property |
| A.all the modern material possession | B.eating while talking on the phone |
| C.the decline in teens’ morality | D.all the communication equipment |

The climate of any place is the kind of weather. It usually has over a long period of time. The houses we live in, the clothes we wear, the foods we eat depend on the climate of the place where we live.
Climate is pattern that is not nearly as simple as we think, and it is affected by many factors. The distance to the North or South Pole or to the equator really matters a lot. If you live near either of the poles, you live in a cold climate, for the place where you live does not get as much or as direct sunshine as a place farther away from the poles. In places close to the equator, the climate is very hot, for they are the parts where the sun shines almost straight down.
Whether rain or snow falls makes a great difference to the climate. In hot, dry deserts, little rain falls, but in a hot rain forest, the amount of rainfalls is far larger than that in a desert, for there is a heavy rain almost every day, even several times per day. Though a rainforest and a desert may be the same distance from the equator, their climates are rather different from each other.
How much rain or snow falls are considered by some to be determined by the winds, the surrounding mountains and the currents(水流) in nearby seas and so on. In short, it is a very complex natural phenomenon.
