问题     Given the advantage of electronic money, you might think that we should move quickly to the cashless society in which all payments are made electronically【C1】______, a true cashless society is probably not around the corner. Indeed, predictions have been【C2】______for two decades but have not yet come to fruition. For example, Business Week predicted in 1975 that electronic means of payment would soon "revolutionize the very【C3】______of money itself," only to【C4】______itself several years later. Why has the movement to a cashless society been so【C5】______in coming?
    Although electronic means of payment may be more efficient than a payments system based on paper, several factors work【C6】______the disappearance of the paper system. First, it is very【C7】______to set up the computer, card reader, and telecommunications networks necessary to make electronic money the【C8】______form of payment. Second, paper checks have the advantage that they【C9】______receipts, something that many consumers are unwilling to【C10】______. Third, the use of paper checks gives consumers several days of "float" — it takes several days【C11】______a check is cashed and funds are【C12】______from the issuer’s account, which means that the writer of the check can earn interest on the funds in the meantime.【C13】______electronic payments are immediate; they eliminate the float for the consumer.
    Fourth, electronic means of payment may【C14】______security and privacy concerns. We often hear media reports that an unauthorized hacker has been able to access a computer database and to alter information【C15】______there. The fact that this is not an【C16】______occurrence means that dishonest persons might be able to access bank accounts in electronic payments systems and【C17】______from someone else’s accounts. The【C18】______of this type of fraud is no easy task, and a new field of computer science is developing to【C19】______security issues. A further concern is that the use of electronic means of payment leaves an electronic【C20】______that contains a large amount of personal data. There are concerns that government, employers, and marketers might be able to access these data, thereby violating our privacy. [br] 【C16】
选项 A、unsafe
B、unnatural
C、uncommon
D、unclear
答案 C
解析 本题是对语义及形容词的综合考查(unsafe不安全的；unnatural不自然的：uncommon不普遍的；unclear不清楚的)。上文讲到有不法分子会侵入计算机数据库更改信息。本句进行阐述，并总结这种情况是比较普遍的，此处用了双重否定(not uncommon)。双重否定是两个表示否定意义的形式(比如否定前缀、否定后缀、否定副词等)同时使用，表示肯定的含义。
