问题 远程教育(distance education)与传统教育相比有两大区别，即远程教育具有灵活性和开放性，不受时空和学习进度的限制。教师在一处授课，而学生在另一处学习，打破了时空限制。授课可以实时或非实时进行，正如五花八门的课程一样，远程教育的模式也是多种多样的。一般而言，远程教育有三种基本的传播模式：电视现场直播，完整的或经过压缩的信息传播以及基于计算机的教学。当然，也可以综合应用这些模式。例如：以播放录像带为主的课程可以经由卫星或万维网播放。
选项
答案There are two key differences between distance education and traditional education. Distance education possesses flexibility and openness, irrespective of time, space, or the pace of learning. Here an instructor teaches, and somewhere else a student learns, breaking barriers of time and space. Instruction may take place in real time or on a time-delayed basis. Distance education modes are as varied as the courses themselves. Generally speaking, there are three basic modes of transmission in distance education; live TV broadcasts, transmission of complete or compressed information and computer-based instruction. Of course, all these modes can also be used in combination. For instance, broadcasts via satellite or the World Wide Web can be added in courses conducted primarily with videotapes.
