 Videoconferencing is nothing more than a television set or PC monitor with a camera Through the videocenferencing, not only your voice but also your face, the surroundings and any other graphic and phisical C)images can be captured and transmitted through the communication system with or without wires. Of course, when you go into the details, the technology involved is very I)advanced and the subject matter littered with jargon.(“会遇到很多的专门术语”,这说明the technology是很专业,很深奥,很先进的)

   Such as ISDN (Integrated Services Digital Network), POTS (Plain Old Telephone Service) or the L)concepts behind bandwidth, latency and isochrony which are used to explain how videoconferencing works. (which从句的先行词是第5小题要填的词,which are used to explain how videoconferencing works“用于解释视频会议工作原理的......”)

  Good people communication is O)important in any business, and the more interaction you can achieve, the more likely it is that your G)decisions will be the right ones. Videoconferencing not only allows you to speak to people in different locations, but also note E)facial expressions and gestures that let you know what the other person is really thinking. Meetings are made more B)effective by sharing documents and computer applications that a simple telephone cannot F)manage.N)increasingly, organizations are discovering the competitive advantages and the power of videoconferencing. With advances in performance, economical pricing, the ability to J)integrate essential meeting tools and connectivity to global telephone networks and standardized videoconferencing protocols, videoconferencing is now a practical reality for any organization. (最后一段说明电视会议有很多优点,可以“具备与基本会议工具较强的兼容能力”等,来说明电视会议已经成为a particial reality“一个实用的现实工具”)
