问题 Online services work by providing users with ______.
How can the users of terminals without processing capability acquire the necessary information?
选项 A、They can simply use a keyboard or a mouse.
B、They should use a modem to maintain the host system.
C、They should connect their computer to a satellite system.
D、They can access its base through the programs on the system.
答案D
解析 本题为细节题。根据文章第一段第二句话"Users of so-called“dumb”terminals(i．e．those without processing capability)simply access information base via programs stored on the system．”可知，“聋哑”终端，也就是不具有信息处理能力的终端，其使用者可以通过储存在系统内的程序来利用信息库。因此答案为D。
