问题     Nowadays, amateur photography has become a troubling issue. Citizens of rich countries have got used to being watched by closed-circuit cameras that【C1】______roads and cities. But as cameras【C2】______and the cost of storing data decreases rapidly, it is individuals who are taking the pictures.
    Some 10,000 people are already testing a【C3】______of Google Glass. It aims to reproduce all the functions of a smartphone in a device placed on a person’s nose.

    The bigger worry is for those in front of the cameras, not【C17】______them. The web is filled with sneaky photos of women,【C18】______in public places. Wearable cameras will make such furtive photography easier. The combination of cameras everywhere—in bars, on streets, in offices, on people’s heads—is a powerful and【C19】______one. We may not be far from a world【C20】______which your movements could be tracked all the time.
