    The strong fear of high school math is lost here among the blue light of computer screens and the sounds of typing keyboard．
    A fanfare （喇叭声） plays from a speaker as a student passes a chapter test．Nearby another student is watching a video lecture．Another works out a math problem in her notebook before clicking on a multiple-choice answer on her screen．
    Their teacher at Agoura High School, US, Russell Stephans, sits at the back of the room, watching as scores pop up in real time on his computer grade sheet．One student has passed a level, the data shows; another is retaking a quiz．
    "Whoever thought this up makes life so much easier," Stephans says．
    This textbook-free classroom is by no means the norm（常态）, but it may be someday．Slowly, but in increasing numbers, schools across the US are replacing the heavy and expensive textbook with its lighter and cheaper cousin: the digital textbook．
    A digital textbook can be downloaded, projected and printed, and can range from simple text to a course filled with multimedia and links to Internet content．Some versions （版本） must be purchased; others are "open source" —free and available online to anyone．
    Some praise the technology as a way to save schools' money, replace outdated books and better engage students．Others say most schools don't have the resources to join in, or they question the quality of open-source content．
    Paper books still hold the highest percentage of the US textbook market, with digital textbooks making up less than 5 percent, according to analyst Kathy Mickey of Simba Information, a market research group．
    But that is changing, as grade schools follow the lead of US universities and schools in other countries, including South Korea and Turkey．
    California made the largest embrace （拥抱） of digital textbooks this summer when it approved 10 free high school math and science titles developed by college professors．The state left the choice to use them up to individual schools．
    "The textbooks are outdated, as far as I'm concerned, and there's no reason why our schools should have our students pull around these old-fashioned and heavy and expensive books," Governor Arnold Schwarzenegger said this summer．
    But some disagree with the idea that digital textbooks will improve education quality．
    "Keep in mind that with open-source materials, you have to ask: 'Where are they coming from?'" said Jay Diskey, executive director of the Association of American Publishers' school division．"Is it a trusted source? Is it based on real research?"
    Diskey said traditional textbooks offer a comprehensive course, while some open-source texts provide only bits and pieces．"There can be quite a difference of content and accuracy," he said．"In many cases, you get what you pay for．"
    【小题1】The writer's purpose in writing the passage is to  ____    .

    A．explain how to use digital textbooks
    B．predict the future of paper textbooks
    C．describe the current use of digital textbooks and present arguments about it
    D．explain the difference between paper textbooks and digital ones
    【小题2】What is Schwarzenegger's opinion of traditional textbooks?
    A．He is against getting rid of them．
    B．He wants to have them replaced with digital ones．
    C．Soon they will no longer be used．
    D．He believes that they are to blame for the poor quality of education in California
    【小题3】Diskey holds the view that      .
    A．the government shouldn't strengthen the use of open-source digital texts
    B．digital textbooks make up for the shortcomings of traditional textbooks．
    C．paper textbooks and digital ones both have advantages
    D．traditional textbooks have more reliable content
    【小题4】According to the text, which of the following is TRUE?
    A．Math is easier with the use of computers．
    B．It is believed that digital books will replace traditional ones．
    C．Textbook-free classes are the main form of teaching in the US schools．
    D．Not all people are in favor of replacing paper textbooks with digital ones．

    In a recent announcement, Harvard and the Massachusetts Institute of Technology（MIT）said that they have joined forces to offer free online courses in an effort to attract millions of online learners worldwide.
    Beginning this fall, a number of courses developed by teachers at both universities will be offered online through a new $60 million program, known as edX. “Anyone with an Internet connection anywhere in the world can use our online courses,” Harvard President Drew Faust said during a meeting to announce the plan.
    MIT has offered a program called OpenCourseWare for ten years that makes materials from more than 2,000 classes free online. It has been used by more than 100 million people. In December, the school announced it also would begin offering a special certificate, known as MITx, for people who complete certain online courses. Harvard has long offered courses to a wider population through a similar program.
    The MITx will serve as the foundation for the new learning platform.
    MIT President Susan Hockfield said more than 120,000 people signed up for the first MITx course. She said Harvard and MIT hope other universities will join them in offering courses on the open-source edX platform.
    “Fasten your seatbelts,” Hockfield said.
    Other universities, including Stanford, Yale and Carnegie-Mellon, have been experimenting with teaching to a global population online.
    The Harvard-MIT program will be monitored by a not-for-profit（非盈利的）organization based in Cambridge, to be owned equally by the two universities. Both MIT and Harvard have provided $30 million to start the program. They also plan to use the edX platform to research how students learn and which teaching methods and tools are most successful.
    【小题1】According to this text, edX is _______.

    A．a part of the free MIT OpenCourseWare
    B．a free computer program by MIT and Harvard
    C．a Harvard-MIT platform of free online courses
    D．a free program online for universities worldwide
    【小题2】What is said about online education in the text?
    A．Universities have been trying online courses.
    B．About 2,000 online courses have been offered.
    C．Over 100 million people have finished courses online.
    D．Stanford and Yale together have courses similar to edX.
    【小题3】The underlined part in the text probably means “        ”.
    A．Get ready for the difficulties
    B．Get ready for this educational change
    C．Get prepared to complete the online courses
    D．Get prepared to make materials for the edX courses
    【小题4】What can be said about MITx according to the text?
    A．It is first offered as part of the edX learning program.
    B．It is another free MIT-Harvard online learning program.
    C．It is a standard to recognize online learners’ achievement.
    D．It is a new kind of free online course of Harvard and MIT.

    For many blind people, computers are inaccessible. It can cost $1,000 to purchase “screen reader” software, but two blind computer programmers from Australia have solved this problem.
    Queensland University of Technology (QUT) graduate James Teh and business partner Michael Curran developed a free, open-source program, called NVDA, which provides a voice to read the words on a computer screen as the cursor(光标) moves over them. NVDA won the blind inventors an award in the grand final program of the ABC’s New Inventors, which aired on September 23. They took home the award for an invention that “might make a real difference to people’s lives or the environment.”
    “A sighted person takes for granted that they can sit down at any computer and use it,” Mr Teh said. “We really are in the information age — everything is online these days. So access to computers for the blind is very important, which is why we wanted our software to be free.”
    Mr Teh, who majored in software engineering at QUT, said blind students typically didn’t have the money to purchase “screen reader” technology, at the time in their life when they most needed it. Now NVDA could be downloaded on to anyone’s personal computer free of charge.
    “It can also be copied to a USB stick, which can be used on any PC at school or university, with no installation required,” he said.
    Mr Teh and Mr Curran have drawn on their own experience as blind computer users to develop a product which has some unique features. For example, as the mouse moves up and down the screen, a sound becomes higher and lower to let you know where the cursor is located.
    NVDA has been translated into 27 languages, thanks to volunteer translators. To date, there have been over 50,000 downloads.
    Mr Teh and Mr Curran have been working on the project since 2006. They worked on their product without any pay for two years. When Mozilla offered some funding in 2008, Mr Teh was able to quit his day job and work full-time developing NVDA.
    【小题1】NVDA won an award in the program of the ABC’s New Inventors because it _____.

    A．causes no harm to the environmentB．influences people’ s lives
    C．is aiming at blind peopleD．is easy to use
    【小题2】Why did James Teh and Michael Curran want their software to be free?
    A．They got funding from Mozilla.
    B．They belonged to a volunteer group.
    C．They wanted to help the blind.
    D．They wanted people to give up “screen reader” software.
    【小题3】What do we know about Teh and Curran?
    A．They are studying at QUT.B．They are good at translating.
    C．They know how the blind feel.D．They began to develop NVDA in 2008.
