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.
【C6】
选项 A、for
B、against
C、with
D、on
答案B
解析 本填空选择一个介词，此介词与动词work构成动词词组作谓语，主语线索是several factors，宾语线索是the disappearance of the paper system。本句子之前出现了一个让步(转折)关系的句子，即Although electronic money might be more convenient and may be more efficient than a payments system based on paper(尽管电子货币可能比基于纸的支付系统更为方便和有效率)，这说明本句子要表达与其相反的意思，四个选项中最合理的是B项against，代入句中的意思就是“几个因素(several factors)对抗(work against)纸质系统的消亡(the disappearance of the paper system)，而这正好与前一句构成让步转折的关系，也与整篇文章的中心主线一致。A项for所构成的work for和D项on所构成的work on表达的意思是“致力于，为了”，这个意思完全错误，与文章主线也相违背，予以排除。C项with所构成的work with表示“与……一起工作”，与本题意无关。
