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 textbook is beneficial to the students because______.
选项 A、it stores the fixed material on different digital machines
B、it tests the students to make them more confident
C、it automatically presents movies based on the students’ preference
D、it automatically matches learning material to students’ needs
答案D
解析 推理判断题。本题考查个性化教材对学生有益的原因。原文第四段第二句提到，存储于一系列数字化设备上的教材将自动进行调整。紧接着具体解释了当学生学习某一课题时，个性化教材如何根据学生需求自动跟进，由此可推知，D)“它可以自动将学习材料和学生的需求相匹配”是对第四段介绍的个性化教材优点的概括，故为答案。A)“它在不同的数字化机器上存储固定的材料”与第四段第一句的信息相矛盾，它所存储的是不同进度的材料，故排除；B)“它测试学生以使他们更加自信”与第四段第三句的信息不符，测试学生的目的是评估学生是否掌握了某一部分知识，而非使学生更加自信，故排除；C)“它会根据学生的喜好自动呈现电影”是对第四段第一句相关信息偷换概念，依据用户的喜好和浏览历史，为用户挑选不同的电影是Netflix网络服务平台的优势，故排除。
