题目解答
答案
A. Because students can communicate with teachers, professors or other students in class.
解析
考查要点：本题考查对“e-learning（电子学习）”互动性的理解，需要结合选项判断作者认为e-learning互动的核心原因。
解题思路：
- 明确“interactive（互动）”的定义：互动强调双向或多向的交流与反馈，而非单向的信息接收。
- 对比选项：
- 选项A提到“交流”，直接对应互动的核心特征。
- 选项B强调时间灵活性，与互动无关。
- 选项C描述单向的视频观看，属于传统单向教学形式。
- 关键结论：只有选项A体现了互动的本质。
选项分析
选项A
“Because students can communicate with teachers, professors or other students in class.”
- 核心词：“communicate（交流）”直接对应“interactive（互动）”。
- 逻辑：e-learning通过在线平台（如讨论区、视频会议）实现学生与教师、学生之间的实时或非实时交流，这是互动的关键表现。
选项B
“Because students can do homework any time.”
- 问题：此选项强调“时间灵活”，但完成作业是单向行为（学生→系统），缺乏互动。
- 排除理由：灵活性是e-learning的优点，但与“互动性”无关。
选项C
“Because students can watch their teachers give lectures on video tapes.”
- 问题：观看录播视频是单向的信息接收（教师→学生），没有反馈或互动环节。
- 排除理由：这与传统电视教学类似，属于单向传播，无法体现互动性。
最终结论：只有选项A明确体现了“互动”的核心特征。
