问题     For years, high school students have received identical textbooks as their classmates. Even as students have different learning styles and abilities, they are force-fed the same materials. " Imagine a digital textbook where because I’m a different person and learn differently, my book is different than your book," said Richard Baraniuk, founder of OpenStax.
    OpenStax will spend two years developing the personalized books and then test them on Houston-area students. The books will also go through a review and evaluation process similar to traditional textbooks. Baraniuk expects 60 people to review each book before publication to ensure its quality.
    The idea is to make learning easier, so students can go on to more successful careers and lives. Baraniuk isn’t just reproducing physical textbooks on digital devices, a mistake e-book publishers have made. He’s seriously rethinking that the educational experience should be in a world of digital tools. To do this means involving individuals with skills traditionally left out of the textbook business. Baraniuk is currently hiring cognitive scientists and machine learning experts. Baraniuk wants to use the tactics(策略)of Google, Netflix and Amazon to deliver a personalized experience. These Web services all rely on complex algorithms(算法)to automatically adjust their offerings for customers.
    Just as Netflix recommends different movies based on your preferences and viewing history, a textbook might present materials at a different pace. The textbook—which will be stored on a range of digital devices—will automatically adjust itself thanks to machine learning. As a student learns about a topic, he or she could be interrupted by brief quizzes that evaluate whether he or she masters the area. Depending on how the student does, the subject could be reinforced with more material. Or a teacher could be automatically e-mailed that the student is struggling with a certain concept and could use some one-on-one attention.
    This personalized learning experience is possible thanks to the wealth of data a digital textbook can track. This data can be used to better track students’ progress during a course. Parents and teachers can monitor a student’s development and provide in time more proper assistance. With personalized learning methods, our students’ talents will be better developed.
What does Richard Baraniuk mean by "the educational experience should be in a world of digital tools"(line 3, Para. 3)?
选项 A、Education should employ the machine to improve learning.
B、Education should involve traditional textbooks in the digital world.
C、Education should include obtaining skills by the use of machine learning.
D、Education should reproduce traditional textbooks on the Web services.
答案C
解析 语义理解题。本题考查理查德·巴拉尼克所说的话的含义。原文第三段第四句和第五句提到，这样做意味着牵涉到传统教材行业遗漏的个人技能。巴拉尼克目前正在招聘认知科学家和机器学习专家。由此可知，教育应该包括技能的习得，而这可以借助于机器学习来完成，故答案为C)。A)“教育应该使用机器来改善学习”是对原文machine learning这一概念的曲解，机器学习是属于人工智能的，它借助的是计算机，而不是笼统的机器的概念，故排除；B)“教育应该将传统教材融人到数字化世界”，是对第三段第四句关键词的曲解，原文强调的是技能而不是传统教材本身，故排除；D)“教育应该在网络服务平台上复制传统教材”，由第三段第二句可知，这不是巴拉尼克研发个性化教材的做法，他认为不应该仅仅在数字化工具上复制传统教材的电子版本，故排除。
