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.
Personalized learning experience may become possible owing to________.
选项 A、a great many digital equipments
B、the students’ continuous progress
C、a great amount of digital information
D、parents’ and teachers’ constant watch
答案C
解析 本题考查个性化学习体验成为可能的原因。根据第五段第一句．这是因为数字化教材可以追踪大量的数据。根据常识可推知，这些数据是数字化信息的范畴，故答案为C。A“大量的数字化设备”只是硬件设施，只有当它们能够提供电子数据时才对个性化学习体验有用，故排除；B“学生不断的进步”是个性化学习体验带来的结果，并非这种学习体验成为可能的原因，故排除；D“家长和老师不断的关注”也是由于大量的数字化数据才得以实现，故排除。
