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, 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 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.

1. According to the passage, the advantage of the new scanning software is that ___.
A.there is no need to scan every page
B.no manpower is needed in operating the scanner
C.it can work much more effectively
D.it can make the scanning process more interesting
2. According to Ishikawa, the scanner works by ___________.
A.changing the shape of the images
B.reducing the size of the images
C.scanning several pages at the same time
D.reconstructing the original page
3. What is Ishikawa’s attitude towards the development of the scanning system?
A.Disapproving.B.Optimistic.
C.Uncertain.D.Cautious.
4. What does the underlined sentence mean?
A.Publishers will probably not welcome the new software.
B.Publishers will refuse to comment on the new software.
C.People will get any book they like more easily.
D.People won’t need to buy books any more with an iPhone.

文章大意:本文为应用文。文章是一篇书评,主要介绍了刘慈溪的作品《三体》的故事梗概、取得的成就及写作特点等。

【推荐1】How would human beings react if we found out we’re not alone in the universe? What if we knew an alien civilization was to invade (入侵) Earth? What would we do?

These are the questions asked in The Three-Body Problem. When a secret military project sends signals into space to get in touch with aliens, an alien civilization in face of destruction receives the signals and plans to invade Earth. Meanwhile, on Earth, people begin to separate into different groups: those who welcome aliens and those who want to fight against them.

The novel was written by Chinese author Liu Cixin and published in 2008. Translated into English in 2014 and almost 20 languages since, it was called an absolute “must-read in any language” by Booklist magazine. Liu has won several awards for it and in 2015, he became the first Asian to win the Hugo Award for Best Novel, the highest award in science fiction.

Just from the title, one could imagine that the text might be heavy with physics terms (术语). But as US writer Jason Heller said: “Indeed this science fiction is full of lengthy passages explaining technical terms. But Liu Cixin supports all of that burning-brain theory with empathetic (感同身受的) characters and thrilling story plots.”

At the very heart of science fiction — and what makes it truly appealing to readers — is the concept of an uncertain future. This allows the author to push the boundaries of readers’ imaginations. Liu fully uses this approach to keep readers anxiously turning the page. While reading, they ask themselves, “What would I do?”

In an interview with The New York Times, Liu said, “China is on the path of rapid modernization and progress, kind of like the US during the golden age of science fiction in the 1930s to the 1960s. The future in the people’s eyes is full of attractions and hope, but also threats and challenges. That makes for very fertile soil.”

1. Why does the author ask the 3 questions in Paragraph 1?
A.To warn us of the crisis Earth is faced with.
B.To introduce the novel The Three-Body Problem.
C.To show the author’s worries about Earth.
D.To remind us to watch out for alien civilizations.
2. What can we know about the novel according to the passage?
A.It is about a fight between aliens and an army on Earth.
B.It was translated into many languages once published.
C.It has gained worldwide recognition and great success.
D.It targets the readers with a good knowledge of physics.
3. What does the underlined part in Paragraph 5 refer to?
A.Explaining very difficult physics terms.
B.Exploring the boundaries of readers’ imaginations.
C.Applying the concept of an uncertain future.
D.Encouraging readers to ask themselves questions.
4. What does Liu mean in the last paragraph?
A.China is now in the golden age of science fiction.
B.The USA authors can’t create science fiction now.
C.Now Chinese people are confused about the future.
D.China’s progress mainly depends on fertile soil.

文章大意:本文是一篇应用文。托马斯·杰斐逊是美国历史上最著名的人物之一,他是美国第三任总统,也是《独立宣言》的作者。他的一生鼓舞人心,但同时又与他的言论和生活方式有些矛盾,因此他成为了许多作家著书的主题。文章介绍了三本与托马斯·杰斐逊有关的著作。

【推荐2】One of the most well-known figures of American history, Thomas Jefferson was the third President of the United States and the author of the Declaration of Independence. His life was an inspiring one and at the same time a little bit contradictory to his statements and way of living life, and thus he has formed the subject of a lot of authors’ books.

Jefferson and his time

   

This is a Biography of the life of Jefferson published in 6 volumes over a very long period of 34 years staring from 1948 till 1982.


Read it For:

It is an entire collection introducing all aspects of Jefferson’s life in great details from his childhood till his last days. For history enthusiasts, this is a wonderful book that will give you insight into the life of one of the most memorable American leaders.


Don’t Read it For:

This series is a biography and strictly a work of non-fiction. It is reading about the life of a person and might get boring for some.

American Sphinx

   

An interesting yet strange book, this piece of writing is not an attempt to shed light on the life of Jefferson but rather an attempt to understand his mind. Jefferson was one who spoke something but did the complete opposite of it.


Read it For:
This book tries to analyze Jefferson’s life but does not do it in a way that criticizes him or idolizes him. This National Award winning book perfectly balances the act of examining someone’s acts and general behavior and trying to figure out the reason behind his contradictory statements and acts.
Don’t Read it For:

If you are searching for a book about Jefferson’s life, this is not for you. It covers a few events of his life, not his entire life.

This Political Biography by Meacham takes you on a journey into the world that Jefferson lived in and saw it through his eyes. It shows how Jefferson formed the world around him and handled situations and people to shape the American political system as it is today.

The Art of Power

   

Read it For:

The depth with which this book is written is commendable. It is noted that the work done by Meacham in this book puts you inside Jefferson’s head and makes you understand what it would be like to be Jefferson.


Don’t Read it For:

While this book shows the genius of Jefferson, it can come off as bias, showing Jefferson in a very positive light and his opponents in a very negative light.

【推荐3】Today we’ll talk about reading. When we read a text, our eyes move across a page in short, quick movements. We recognize words usually when our eyes still fixate(停留, 凝视). Each time they fixate, we see a group of words. This is known as the recognition span or the visual span(视幅). The length of time for which the eyes stop varies from person to person. It also varies within any parson according to his purpose in reading and his familiarity with the text. In addition, it can be affected by such factors as lighting and tiredness.
Unfortunately, in the past, many reading improvement courses have concentrated too much on how our eyes move across the page. As a result of this misleading emphasis(强调)on the purely visual aspects of reading, many exercises have been designed to train the eyes to see more words at one fixation. For example, in some exercises, words are flashed on to a screen for a tenth of a second. One of the exercises has required students to fix their eyes on some central point, taking in the words on either side. Such word patterns are often formed in the shape of pyramids(金字塔), so the reader takes in more and more words at each successive(连续的)fixation. All these exercises are very clever, but it’ s one thing to improve a person’s ability to see words and quite another thing to improve his ability to read a text efficiently. Reading requires the ability to understand the relationship between words. Consequently, for these reasons, many experts have now begun to question the usefulness of eye training, especially since any approach which trains a person to read isolated(孤立的)words and phrases would seem unlikely to help him in reading a continuous text.
1. The time of the recognition span can be affected by the following factors except _______.
A.1ighting and tiredness
B.the length of a group of words
C.one’s purpose in reading
D.one’s familiarity with the text
2. The author may believe that reading ______________.
A.requires a reader to take in more words at each fixation
B.requires a reader to see words more quickly
C.demands a deeply-participating mind
D.demands more eyes than mind
3. What does the author mean by the underlined sentence in the second paragraph?
A.The ability to see words is not needed for an efficient reading.
B.The reading exercises mentioned are useless for reading.
C.The reading exercises mentioned can’t help improve reading.
D.The reading exercises mentioned have done a great job so far.
4. Which of the following is NOT true? _______________.
A.The visual span is a word or a group of words we see each time
B.Many experts began to question the efficiency of eye training
C.The emphasis on the purely visual aspects is misleading
D.The eye training will help readers in reading a continuous text
5. The tune of the author in writing this text is _________________.
A.criticalB.neutral
C.supportiveD.optimistic
