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. Its flexible frame holds both a camera and a【C4】______screen, and makes it easy for users to take photos, send【C5】______and search for things online. Glass may fail, but a wider revolution is under way. In Russia, where insurance【C6】______is common, at least 1 million cars already have cameras with them that film the road ahead. Police forces in America are starting to【C7】______officers with video cameras, pinned to their uniforms, which record their interactions with the public. Widespread recording can already do a lot of good. Car-cams can help resolve insurance claims and encourage people to drive better. Police-cams can discourage criminals from making groundless complaints【C8】______police officers and officers from【C9】______the suspects. Optimists see broader benefits【C10】______Plenty of people carry activity trackers to【C11】______their exercise or sleep patterns; cameras could do the job more effectively, perhaps also【C12】______their wearers' diets. "Personal black boxes" might be able to transmit pictures【C13】______their owner falls victim to an accident or crime. Not everybody will be【C14】______by these prospects. A perfect digital memory would probably be a pain, preserving unhappy events as well as【C15】______ones Suspicious spouses and employers might feel【C16】______review it. 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.

单选题
【C2】
【正确答案】
B
【答案解析】解析：本句提到个人成为拍照的主力军，其中一个因素是and后面提到的存储数据的成本骤降(the cost of storing data decreases rapidly)，因此空格处填入的单词应是个人成为拍照主力军的另一因素。B项shrink意为“缩小”，指照相机体积变小，方便人们携带。
【答案解析】解析：本句提到至少100万辆车上安装了摄像头以摄录前方道路。为什么这么多的车辆装上了摄像头?结合主语insurance及下一段第二句提及的行车记录仪有助于解决保险索赔(Car-cams can help resolve insurance claims)，说明人们想应对一个经常出现的保险问题。A项fraud“欺骗，诈骗”与insurance搭配指“保险诈骗”。
【答案解析】解析：上文提到警用摄像头能record their interactions with the public，因此可推测其作用是正面的，有助于保护警察及公众的利益。本句提到罪犯进行无端控诉(making groundless complaints)，由此可推测police officers(警员)是控诉的对象，A项against和complaint搭配后表示“对……进行控诉”，表示对象。
【答案解析】解析：上段提到Optimists see broader benefits，本句的主语not everybody对此提出相反的态度，下句提到一台完美的数字储存器也很可能会带来烦恼(would probably be a pain)，可以推断并不是每个人都对此感到高兴。原文已有否定not everybody．因此空格处所填单词应是褒义词，B项thrilled“激动的”符合语义。
