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.
【C20】
选项 A、chunk
B、chip
C、path
D、trail
答案D
解析 本填空所选择的名词是动词leaves的宾语，而做出leaves动作的主语是use of electronic means of payment(使用电子支付方式)，本句仍然是在谈论电子支付的风险。本名词之后有定语从句that contains a large amount of personal data on buying habits(包含大量关于购买习惯的个人信息)，四个名词中最合理的是D项trail(踪迹，痕迹)，即包含大量关于购买习惯的个人信息的电子痕迹。A项chunk(大部分，厚块)和B项chip(芯片)明显不合理，因为使用电子支付方式是不会留下电子厚块或电子芯片的。而C项path(道路)无法直接被electronic修饰。
