1.D 2.B 3.C 【解析】 Like many other people, I love my smartphone, which keeps me connected with the larger world. I also love my laptop, because it holds all of my writing and thoughts. However, I know there are times when I need to move away from these devices and truly communicate with others. On occasion, I teach a course called History Matters to a group of higher education managers. My goals for the class include a full discussion of historical themes and ideas. Because I want students to thoroughly study the materials and exchange their ideas with each other in the classroom, I have a rule — no laptop, iPads, phones, etc. When students were told my rule in advance of the class, some of them were not happy. Most students assume that my reasons for this rule include unpleasant experiences in the past with students misusing technology. There’s a bit of truth to that. Some students assume that I am anti-technology. There’s no truth in that at all. The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversations and truly engage complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas. I want students to dig deep within themselves for inspiration and ideas. I’ve been teaching my history class in this way for many years and the evaluations reflect student satisfaction with the environment that I create. Students realize that with deep conversation and challenge, they learn at a level that helps them keep the course materials beyond the classroom. Questions: Why were some of the students in the history class unhappy? What can be learned from this passage? What can be inferred from the passage about the use of technology in classrooms? 1.此题为听力题，解析略。 2.此题为听力题，解析略。 3.此题为听力题，解析略。
