问题 Online services work by providing users with ______.
If you copy the online information onto your PC device, you will ______ .
选项 A、save the time of connecting to the online system
B、reduce the risk of losing information
C、pay just local telephone charges
D、get local information only
答案A
解析 本题为细节题。根据文章第二段最后一句话"Some online systems allow users to copy large volumes of information onto a local memory storage device，which also reduces the time the user is connected to the online system．”可知，通过把大量信息复制到本地的PC机，可以缩减网络连接的时间。因此答案为A。
