阅读理解 High Speed Book ScannerSimply 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.1.According to the passage, the advantage of the new scanning software is that ______.A.there is no need to scan every pageB.it can work much more effectivelyC.no manpower is needed in operating the scannerD.it can make the scanning process more interesting2.According to Ishikawa, the scanner works by_____.A.changing the shape of the imagesB.reducing the size of the imagesC.reconstructing the original pageD.scanning several pages at the same time3.What is Ishikawa’s attitude towards the development of the scanning system?A.Optimistic.B.Uncertain.C.Disapproving.D.Cautious.4.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.

BCAC解析文章介绍了一种非常先进的扫描仪。1.B 根据文章第二段内容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.可知这种扫描仪更高效。故B正确。2.C 细节题。根据第二段最后一行explaining the system used to reconstruct the original page.可知C正确。3.A 猜测态度题。根据文章内容可知他对于这种机器很乐观。4.C 猜测句意题。这里是指还要出版商对于这种机器的态度，可能出版商对于这种机器吃反对态度，因为扫描书本以后就成了电子版本，可能会影响到他们的印刷版的书本的销售。

就是这个解释
