问题 The basic delivery system for the distance-education mega-universities is television, supplemented by other technologies or even some online instruction in more developed countries. Some distance-education systems use two-way interactive video connections to particular locations where students gather; others supplement with the Internet, and still others deliver only by Internet. With video-and-audio-streaming now available, the Internet appears to be the technology of choice for systems where students have access to computers. Of course, these technologies merely add to the radio-delivered courses that have been offered for years in many countries around the world.

选项

答案大型远程教育学校的基本传输系统是电视，并辅以其他技术，更发达的国家则会辅以在线教学。一些远程教育系统使用双向交互式视频连接到学生聚集的另一端；另一些则辅以互联网，也有一些只通过互联网进行教学。随着视频和音频流媒体技术的普及，互联网似乎成为学生使用计算机系统的首选技术。当然，这些技术仅仅是在世界上许多国家多年来提供的无线电授课方式的基础上增加的。
