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.
【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。
