单选题

From the passage we can learn that ______.

A students with iPads have less discussion in class

B students get more fun from learning with iPads

C iPads help students save time waiting for buses

D iPads prevent students from cheating in exams

解析：
本题是细节题。第二段提到“students now have much more time for discussion”，与 A项意思相反。第四段提到“The class has become much more interesting and creative（课堂变得更有意思，也更有创造力）”，B项符合。第五段提到“I can listen to my language material or watch teaching videos on the bus”，即学生可以节省时间，在等车时继续学习，C项表述不当。D项并未提及。答案为B项。
