问题 Information highway means people can______.
Users can chat on net anywhere because of______.
选项 A、a social and commercial environment
B、high speed networking and computing
C、three rapidly evolving technologies
D、simultaneous use of voice, video, image and data
答案B
解析 由题干中的anywhere与原文定位句中location-independent相对应，可定位到原文首段末尾A location-independent user environment，which uses high speed networking and computing for multimedia communications．[精析] 逻辑推理题。题干问的是使用者可以随时随地通过网络交谈的原因。联系上下文，可知uses high speed networking and computing for multimedia communications为原因所在。B)表述与之相符，故为正确答案。[排除干扰] A)、C)和D)均在原文出现，但是联系原文可推知它们并非题干所问的直接原因，都是间接原因，不全面也不完整，故均排除。
