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.

63. According to the passage, the advantage of the new scanning software is that ______.

A. there is no need to scan every page

B. it can work much more effectively

C. no manpower is needed in operating the scanner

D. it can make the scanning process more interesting

64. According to Ishikawa, the scanner works by_____.

A. changing the shape of the images B. reducing the size of the images

C. reconstructing the original page D. scanning several pages at the same time

65. What is Ishikawa’s attitude towards the development of the scanning system?

A. Optimistic. B. Uncertain. C. Disapproving. D. Cautious.

66. What does the underlined sentence mean?

A. People will get any book they like more easily.

B. Publishers will refuse to comment on the new software.

C. Publishers will probably not welcome the new software.

D. People won’t need to buy books any more with an iPhone.

Telecommuting(远程办公) will have major effects on the worlds of work and family life. However, its biggest effect will be in the area of individual freedom, responsibility and time management.

Work and workplaces will change greatly. Offices may become smaller, as fewer desks are needed. There will be greater need for high-speed Internet connections to link the office and the home, and even homes to other homes, as other employees also begin working at home. Hours spent in traffic jams, and fights for parking should diminish, as workers travel less.

Family life will also change. Both husbands and wives will be able to arrange their work around family commitments such as taking children to school, cooking, spare time activities, and so on. However, households(家人) will also have to set aside areas for work-particularly if more than one person is telecommuting.

However, although the ideas of more time at home and less time traveling are attractive, there are some drawbacks to telecommuting. People may feel that they cannot escape from work, work longer hours, or become less social. The quality of work may suffer because of fewer face-to-face interactions with other employees, and there may be delays if other workers are not immediately available. Telecommuters may also feel isolated. A major change will be in the way people think about work as a place or an institution. Instead, they will focus on the task or the product. Workers may feel less loyal to a company.

In conclusion, the effects are difficult to predict because they depend on the extent to which telecommuting becomes popular. At the same time, however, telecommuting could be the start of a major societal shift, possibly as big as the Industrial Revolution which created our present ideas of work.

64. This passage was mainly written to tell us _____.

A. about the advantages of telecommuting

B. how telecommuting will change the world

C. that telecommuting will affect family life D. how to telecommute in the future

65. What is Paragraph 4 mainly about?

A. The disadvantages of telecommuting. B. Setting aside areas for work.

C. The future of telecommuting. D. The employees’ focus on work.

66. With telecommuting in the future, which of the following will be reduced?

A. Working hours and family time. B. Face-to-face communication.

C. Spare time and individual freedom. D. Spending time with friends.

67. What can we infer from the passage?

A. Telecommuting will change the world completely.

B. There will be no traffic jams because of telecommuting.

C. Work efficiency will increase through telecommuting.

D. Telecommuting workers will likely change their jobs.

If you are a recent social science graduate who has had to listen to jokes about unemployment from your computer major classmates, you may have had the last laugh. There are many advantages for the social science major because this high-tech “Information Age” demands people who are flexible and who have good communication skills.

There are many social science majors in large companies who fill important positions. For example, a number of research studies found that social science majors had achieved greater managerial success than those who had technical training or pre-professional courses. Studies show that social science majors are most suited for change, which is the leading feature (特点) of the kind of high speed, high-pressure, high-tech world we now live in.

Social science majors are not only experiencing success in their long-term company jobs, but they are also finding jobs more easily. A study showed that many companies had filled a large percentage of their entry-level positions with social science graduates. The study also showed that the most sought-after quality in a person who was looking for a job was communication skills, noted as “very important” by 92 percent of the companies. Social science majors have these skills, often without knowing how important they are. It is probably due to these skills that they have been offered a wide variety of positions.

Finally, although some social science majors may still find it more difficult than their technically trained classmates to land the first job, recent graduates report that they don’t regret their choice of study.

1. By saying that “you may have had the last laugh” in the first paragraph, the author means that you may have _______.

A. earned as much as computer majors B. stopped joking about computer majors

C. shared the jokes with computer majors D. found jobs more easily than computer majors

2. Compared with graduates of other subjects, social science graduates ______.

A. are likely to give others pressure B. are equally good at computer skills

C. are better able to deal with difficulties D. are ready to change when situations change

3. Which of the following is true about the communication skill?

A. Social science majors do not know they have had these skills.

B. Many companies prefer to employ those with good communication skills.

C. These skills have been considered very important by social science majors.

D. Computer majors have been offered a wide variety of positions because of these skills.

4 According to the text, what has made it easy for social science graduates to find jobs?

A. Part-time work experience. B. Skills in expressing themselves.

C. Willingness to take low-paid jobs. D. Readiness to gain high-tech knowledge.

5. The underlined word “land” in the last paragraph probably means _______.

A. successfully get B. lose regretfully C. immediately start D. keep for some time
