Digital textbooks are changing the way many students learn. All the Fairfax County Public Schools have begun using online course material for their middle- and high-school students. This school year, the schools changed from books to digital textbooks for social studies in its middle and high schools. The change came after digital books were used in 15 schools last year. "Our students come to us technologically ready to use resources from a variety of different places," says Assistant Superintendent Peter Noonan. "The world is changing consistently. The online textbooks can change right along with the events that are happening." There’s an important financial benefit as well. "Usually it is between $50 and $70 to buy a textbook for each student," Noonan says, "which adds up to roughly $8 million for all of our students. We actually have bought all of the online textbooks for our students for just under $6 million."
1. What is happening to the schools in Fairfax County this school year?
2. How much money have schools saved with digital textbooks?
选项 A、$1 million.
B、$2 million.
C、$3 million.
D、$4 million.
答案B
解析 细节推断题。由“Usually it is between $50 and $70 to buy a textbook for each student,”Noonan says，“which adds up to roughly $8 million for all of our students．We actually have bought all of the online textbooks for our students for just under $6 million．”可知，每个学生电子课本的费用在50-70美元之间，所有学生的电子课本总费用将近800万美元。但实际上，为所有学生买电子课本的费用不到600万美元。也就是说电子课本比纸质课本要节省200多万美元，故选B。
