问题     Given the advantages of electronic money, you might think that we would 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 of such a society 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 might be more convenient and 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【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 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 on buying habits. There are concerns that government, employers, and marketers might be able to access these data, thereby violating on our privacy.
【C16】
选项 A、unsafe
B、unnatural
C、uncommon
D、unclear
答案C
解析 本填空考查形容词，被修饰成分是occurrence(发生的时间)，主语this指代的是上文所讲的“黑客侵入数据库修改存储信息”的事情。根据文章的基本主旨，本句子仍然是在说明电子支付的缺陷。因此可以判断本填空所选择的形容词表示的是对电子支付的不利条件，最佳答案应该是C项uncommon(不常见的)，这样本句的意思就是“黑客侵入数据库修改存储信息并不是不常见的事情(即很常见)”，最符合文章主旨和题意。如果选择A项unsafe(不安全的)，则本句的意思是“黑客侵入数据库修改存储信息并不是不安全的事情(即很安全)”，不能体现出电子支付的缺陷，故排除。B项unnatural(非自然的)和D项unclear(不清楚的)不贴近题意。
