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.
In which aspect have e-book publishers done incorrectly?
选项 A、They have only put emphasis on learning experience.
B、They have made it difficult to have access to an e-book.
C、They have made it rather boring and inconvenient to learn.
D、They have just produced an electronic copy of print textbooks.
答案D
解析 事实细节题。本题考查电子书出版商所犯的错误。定位句提到，只在数字化设备上复制纸质课本，这是电子书出版商所犯的一个错误，D)项是该句的同义转述，故为答案。A)“他们只看重学习经验”、B)“他们使得电子书的使用相当困难”和C)“他们使得学习相当枯燥和不便”，原文均未提及，故排除。
