问题     California has a new program called the Digital Textbook Initiative. "Starting this fall with high school math and science, we will be the first state in the nation — the first state in the nation — to provide schools with a state-approved list of digital textbooks." That was Governor Arnold Schwarzenegger in June, talking about his effort to get schools to use materials available free online. He listed reasons why he thinks digital textbooks make sense.
    California approves traditional textbooks in six-year cycles. Digital ones can offer the latest information. They lighten the load of school bags. They save paper and trees, and make learning more fun and interactive. And above all, he said, they help schools with their finances.
    The state has had to make severe cuts in school spending because of deep financial problems. More than six million students attend California public schools.
    Earlier this year, California invited content developers to offer digital math and science materials for high schools. These had to meet at least ninety percent of the state’s learning requirements. Specially trained teachers examined 16 textbooks and approved ten of them.
    Six of the ten were published by the CK12 Foundation. Co-founder Neeru Khosla says the nonprofit group had been developing digital science and math books for about two years. The foundation paid teachers and other education professionals to write and edit them. The money came from a group financed by the Khosla family. The AMAR Foundation also supports projects in India.
    California cannot require schools to use the digital textbooks. Individual school districts will have to decide for themselves.
    Susan Martimo, a California Department of Education official, says she does not expect widespread use right away. Her best guess is that some schools with a lot of technology will be the first to use them, but only in addition to their traditional books.
    School administrators point out that the texts may be free online, but students need a way to access them. Not everyone has a computer or electronic reader. Schools could print out copies, but that would not help the environment. Also, there is the cost to train teachers to use digital textbooks effectively.
What can be inferred from the last paragraph?
选项 A、Schools are reluctant to print out copies.
B、The use of digital textbooks is not really free.
C、Students need to pay for computers.
D、Training teachers to use the textbooks is not efficient.
答案B
解析 末段提到，网上的书可能是免费的，但学生需要一种方式来使用它们。并不是每个学生都有电脑或电子阅读器，言外之意就是学生为了使用电子教科书可能得花钱买电脑或电子阅读器。末句提到，培训教师有效地使用数字教科书也得花钱。结合这两点可推断出，数字教科书的使用并不是真正免费的，故答案为[B]。[A]是针对末段第三句进行的错误推断。[C]是针对末段第二句设的干扰项。[D]是针对末段末句设的干扰项。
